Jarvis: Physical Examination and Health Assessment, 8th Edition
MULTIPLE CHOICE
- The nurse should measure rectal temperatures in which of these patients? a. Older adult b. Comatose adult c. School-age child d. Patient receiving oxygen by nasal cannula ANS: B Rectal temperatures should be taken when the other routes are impractical, such as for comatose or confused people, for those in shock, or for those who cannot close the mouth because of breathing or oxygen tubes, a wired mandible, or other facial dysfunctions.

- The nurse is teaching a student nurse about the different types of thermometers. When teaching the student about the advantages of the tympanic membrane thermometer (TMT), which statement should the nurse include? a. “Measuring temperature using the TMT is inexpensive.” b. “The rapid measurement of the TMT is useful for uncooperative younger children.” c. “Using the TMT is the most accurate method for measuring body temperature in newborn infants.” d. “Studies strongly support the use of the TMT in children under the age 6 years.” ANS: B The TMT is useful for young children who may not cooperate for oral temperatures and fear rectal temperatures. However, the use of a TMT with newborn infants and young children is conflicting.

- When assessing an older adult, the nurse should recognize that which vital sign changes occur with aging? a. Increase in pulse rate b. Widened pulse pressure c. Increase in body temperature d. Decrease in diastolic blood pressure ANS: B With aging, the nurse keeps in mind that the systolic blood pressure increases, leading to widened pulse pressure. With many older people, both the systolic and diastolic pressures increase. The pulse rate and temperature do not increase with aging. H owever, both the systolic and diastolic pressures increase in many older adults.

- The nurse is examining a patient who is complaining of “feeling cold.” Which is a mechanism of heat loss in the body? a. Exercise b. Radiation c. Metabolism d. Food digestion ANS: B The body maintains a steady temperature through a thermostat or feedback mechanism, which is regulated in the hypothalamus of the brain. The hypothalamus regulates heat production from metabolism, exercise, food digestion, and external factors with heat loss through radiation, evaporation of sweat, convection, and conduction.

- When evaluating the temperature of older adults, the nurse should remember which aspect about an older adult’s body temperature? a. The body temperature of the older adult is lower than that of a younger adult. b. An older adult’s body temperature is approximately the same as that of a young child. c. Body temperature depends on the type of thermometer used. d. In the older adult, the body temperature varies widely because of less effective heat control mechanisms.
ANS: A In older adults, the body temperature is usually lower than in other age groups, with a mean temperature of 36° C.

- Which of these actions illustrates the correct technique the nurse should use when assessing oral temperature with a gla ss thermometer? a. Wait 30 minutes if the patient has ingested hot or iced liquids. b. Leave the thermometer in place for 3 to 4 minutes if the patient is afebrile. c. Shake the glass thermometer down to 37° C before taking the patient’s temperature. d. Place the thermometer in front of the tongue and ask the patient to close his or her lips. ANS: B The thermometer should be left in place 3 to 4 minutes if the person is afebrile and up to 8 minutes if the person is febrile. The nurse should wait 15 minutes if the person has just ingested hot or iced liquids and 2 minutes if he or she has just smoked. A glass thermometer should be shaken down to 35° C, not 37° C, before taking a patient’s temperature. The thermometer should be placed at the base of the tongue, not the front. The correct answer is to leave the thermometer in place for 3 to 4 minutes if the person is afebrile and up to 8 minutes if the person is febrile.

- What technique should the nurse use to accurately assess a rectal temperature in an adult? a. Use a lubricated blunt tip thermometer. b. Insert the thermometer 2 to 3 inches into the rectum. c. Leave the thermometer in place up to 8 minutes if the patient is febrile. d. Wait 2 to 3 minutes if the patient has recently smoked a cigarette.
ANS: A A lubricated rectal thermometer (with a short, blunt tip) is inserted only 2 to 3 cm (1 inch) into the adult rectum and left in place for 212 minutes. Cigarette smoking does not alter rectal temperatures.

- Which technique is correct when the nurse is assessing the radial pulse of a patient? a. Palpate for 1 minute, if the rhythm is irregular. b. Palpate for 15 seconds and multiply by 4, if the rhythm is regular. c. Palpate for 2 full minutes to detect any variation in amplitude. d. Palpate for 10 seconds and multiply by 6, if the rhythm is regular and the patient has no history of cardiac abnormalities. ANS: A Research suggests that the 30-second interval multiplied by 2 is a more accurate and efficient technique when heart rates are normal or rapid and when rhythms are regular, then the 15-seconds interval multiplied by 4 as any one beat error in counting results in an error of 4 beats/minute. If the rhythm is irregular, then the pulse is counted for 1 full minute.

- When assessing a patient’s pulse, the nurse should also notice which of these characteristics? a. Force b. Pallor c. Capillary refill time d. Timing in the cardiac cycle ANS: A The pulse is assessed for rate, rhythm, and force. Pallor, capillary refill time, and timing in the cardiac cycle are not things that should or can be assessed when assessing a patient’s pulse.

- A patient’s blood pressure is 118/82 mm Hg. He asks the nurse, “What do the numbers mean?” Which is the best reply by the nurse? a. “The numbers are within the normal range and are nothing to worry about.” b. “The bottom number is the diastolic pressure and reflects the stroke volume of the heart.” c. “The top number is the systolic blood pressure and reflects the pressure of the blood against the arteries when the heart contracts.” d. “The concept of blood pressure is difficult to understand. The primary thing to be concerned about is the top number, or the systolic blood pressure.”
ANS: C The systolic pressure is the maximum pressure felt on the artery during left ventricular contraction, or systole. The diastolic pressure is the elastic recoil, or resting, pressure that the blood constantly exerts in between each contraction. The n urse should answer the patient’s question and use terms he can understand. The nurse should answer the patient’s question in terms they can understand and not just say it is normal and there is nothing to worry about. The diastolic pressure is the pressure in the vessels when the heart is at rest, not the stroke volume.

- A nurse is helping at a health fair at a local mall. What should the nurse keep in mind when taking blood pressures on a variety of people? a. After menopause, blood pressure readings in women are usually lower than those taken in men. b. The blood pressure of an African-American adult is usually higher than that of a non-Hispanic White adult of the same age. c. Blood pressure measurements in people who are overweight should be the same as those of people who are at a normal weight. d. A teenager’s blood pressure reading will be lower than that of an adult. ANS: B In the United States, an African-American adult’s blood pressure is usually higher than that of a non-Hispanic White adult of the same age. After menopause, blood pressure in women is higher than in men; blood pressure measurements in people who are obese are usually higher than in those who are not overweight. Normally, a gradual rise occurs through childhood and into the adult years. After menopause, blood pressure in women is higher than in men; blood pressure measurements in people who are obese are usually higher than in those who are not overweight; and there is normally a gradual increase in blood pressure through childhood and into the adult years. The incidence of hypertension is twice as high in African-Americans as it is in non-Hispanic Whites.

- The nurse notices that a colleague is preparing to check the blood pressure of a patient who is obese by using a standar d-sized blood pressure cuff. How would this likely affect the blood pressure reading? a. Yield a falsely low blood pressure b. Yield a falsely high blood pressure c. Be the same, regardless of cuff size d. Vary as a result of the technique of the person performing the assessment ANS: B Using a cuff that is too narrow yields a falsely high blood pressure because it takes extra pressure to compress the artery.

- A student is late for his appointment and has rushed across campus to the health clinic. How should the nurse proceed? a. Allow 5 minutes for him to relax and rest before checking his vital signs. b. Check the blood pressure in both arms, expecting a difference in the readings because of his recent exercise. c. Immediately monitor his vital signs on his arrival at the clinic and then 5 minutes later, recording any differences. d. Check his blood pressure in the supine position, which will provide a more accurate reading and will allow him to relax at the same time.
ANS: A A comfortable, relaxed person yields a valid blood pressure. Many people are anxious at the beginning of an examination; the nurse should allow at least a 5-minute rest period before measuring blood pressure. Verifying the blood pressure in both arms only needs to be done once, usually with the first complete physical examination, but exercise should not cause a difference in the readings between arms. Checking the blood pressure in a supine position does not provide a more accurate reading.

- The nurse will perform a palpated pressure before auscultating blood pressure. What is the reason for this? a. More clearly hear the Korotkoff sounds. b. Detect the presence of an auscultatory gap. c. Avoid missing a falsely elevated blood pressure. d. More readily identify phase IV of the Korotkoff sounds.
ANS: B Inflation of the cuff 20 to 30 mm Hg beyond the point at which a palpated pulse disappears will avoid missing an auscultatory gap, which is a period when the Korotkoff sounds disappear during auscultation.

- The nurse is taking an initial blood pressure reading on a 72-year-old patient with documented hypertension. How should the nurse proceed? a. Cuff should be placed on the patient’s arm and inflated 30 mm Hg above the patient’s pulse rate. b. Cuff should be inflated to 200 mm Hg in an attempt to obtain the most accurate systolic reading. c. Cuff should be inflated 30 mm Hg above the point at which the palpated pulse disappears. d. After confirming the patient’s previous blood pressure readings, the cuff should be inflated 30 mm Hg above the highest systolic reading recorded.
ANS: C An auscultatory gap occurs in approximately 5% of the people, most often in those with hypertension caused by a noncompliant arterial system. To check for the presence of an auscultatory gap, the cuff should be inflated 20 to 30 mm Hg beyond the point at which the palpated pulse disappears.

- When auscultating the blood pressure of a 25-year-old patient, the nurse notices that the phase I Korotkoff sounds begin at 200 mm Hg. At 100 mm Hg, the Korotkoff sounds muffle. At 92 mm Hg, the Korotkoff sounds disappear. How should the nurse record this patient’s blood pressure? a. 200/ b. 200/ c. 100/200/ d. 200/100/ ANS: A In adults, the last audible sound best indicates the diastolic pressure. When a variance is greater than 10 to 12 mm Hg between phases IV and V, both phases should be recorded along with the systolic reading (e., 142/98/80).

- A 4-month-old child is at the clinic for a well-baby checkup and immunizations. Which of these actions is most appropriate when the nurse is assessing an infant’s vital signs? a. The infant’s radial pulse should be palpated, and the nurse should notice any fluctuations resulting from activity or exercise. b. The nurse should auscultate an apical rate for 1 minute and then assess for any normal irregularities, such as sinus dysrhythmia. c. The infant’s blood pressure should be assessed by using a stethoscope with a large diaphragm piece to hear the soft muffled Korotkoff sounds. d. The infant’s chest should be observed and the respiratory rate counted for 1 minute; the respiratory pattern may vary significantly.
ANS: B The nurse auscultates an apical rate, not a radial pulse, with infants and toddlers. The pulse should be counted by list ening to the heart for 1 full minute to account for normal irregularities, such as sinus dysrhythmia. Children younger than 3 years of age have such small arm vessels; consequently, hearing Korotkoff sounds with a stethoscope is difficult. The nurse should use either an electronic blood pressure device that uses oscillometry or a Doppler ultrasound device to amplify the sounds. An infant’s respiratory rate should be assessed by observing the infant’s abdomen, not chest, because an infant’s respirations are n ormally more diaphragmatic than thoracic. The nurse should auscultate an apical heart rate, not palpate a radial pulse, with infants and toddlers.

- The nurse is conducting a health fair for older adults. Which statement is true regarding vital sign measurements in aging adults? a. The pulse is more difficult to palpate because of the stiffness of the blood vessels. b. An increased respiratory rate and a shallower inspiratory phase are expected findings. c. A decreased pulse pressure occurs from changes in the systolic and diastolic blood pressures. d. Changes in the body’s temperature regulatory mechanism leave the older person more likely to develop a fever.
ANS: B Aging causes a decrease in vital capacity and decreased inspiratory reserve volume. The examiner may notice a shallower inspiratory phase and an increased respiratory rate. An increase in the rigidity of the arterial walls actually makes th e pulse easier to palpate. Pulse pressure is widened in older adults, and changes in the body temperature regulatory mechanism leave the older person less likely to have fever but at a greater risk for hypothermia. Pulse pressure is widened, rather than decreased , in older adults, and changes in the body temperature regulatory mechanism leave the older person less likely to have fever but at a greater risk for hypothermia. As people age there is a decrease in vital capacity and decreased inspiratory reserve volume. The examiner may notice a shallower inspiratory phase and an increased respiratory rate.

- The nurse is assessing children in a pediatric clinic. Which statement is true regarding the measurement of blood pressure in children? a. Blood pressure guidelines for children are based on age. b. Phase II Korotkoff sounds are the best indicator of systolic blood pressure in children. c. Using a Doppler device is recommended for accurate blood pressure measurements until adolescence. d. The disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children. ANS: D The disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children, as well as in adults. Blood pressure guidelines for children are based on more than just age, but also sex and height. Phase I Korotkoff, not Phase II, is the best indicator of systolic blood pressure. The true statement regarding the measurement of blood pressure in children is that the disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children, as well as in adults.

- What type of blood pressure measurement error is most likely to occur if the nurse does not check for the presence of an auscultatory gap? a. Diastolic blood pressure may not be heard. b. Diastolic blood pressure may be falsely low. c. Systolic blood pressure may be falsely low. d. Systolic blood pressure may be falsely high. ANS: C If an auscultatory gap is undetected, then a falsely low systolic or falsely high diastolic reading may result, which is common in patients with hypertension caused by a noncompliant arterial system.

- When considering the concepts r/t blood pressure, the nurse knows that the concept of mean arterial pressure (MAP) is best described by which statement? a. MAP is the pressure of the arterial pulse. b. MAP reflects the stroke volume of the heart. c. MAP is the pressure forcing blood into the tissues, averaged over the cardiac cycle. d. MAP is an average of the systolic and diastolic blood pressures and reflects tissue perfusion.
ANS: C MAP is the pressure that forces blood into the tissues, averaged over the cardiac cycle. Stroke volume is reflected by t he blood pressure. MAP is not an arithmetic average of systolic and diastolic pressures because diastole lasts longer; rather, it is a value closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it is the pressur e that forces blood into the tissues, averaged over the cardiac cycle.

- A 75-year-old man with a history of hypertension was recently changed to a new antihypertensive drug. He reports feeling dizzy at times. How should the nurse evaluate his blood pressure? a. Blood pressure and pulse should be recorded in the supine, sitting, and standing positions. b. The patient should be directed to walk around the room and his blood pressure assessed after this activity. c. Blood pressure and pulse are assessed at the beginning and at the end of the examination. d. Blood pressure is taken on the right arm and then 5 minutes later on the left arm.
ANS: A Orthostatic vital signs should be taken when the person is hypertensive or is taking antihypertensive medications, when the person reports fainting or syncope, or when volume depletion is suspected. The blood pressure and pulse readings are recorded in the supine, sitting, and standing positions.

- The nurse is counting an infant’s respirations. Which technique is correct? a. Watching the chest rise and fall b. Observing the movement of the abdomen c. Placing a hand across the infant’s chest d. Using a stethoscope to listen to the breath sounds
ANS: B Watching the abdomen for movement is the correct technique because the infant’s respirations are normally more diaphragmatic than thoracic. The other responses do not reflect correct techniques. To count the respirations of an infant the nurse s hould not observe or place a hand on the chest because infants’ respirations are more diaphragmatic than thoracic. The nurse should also not listen with a stethoscope to count respirations because that will influence the infant’s breathing. Instead, watching th e abdomen for movement is the correct technique to count an infant’s respirations because the infant’s respirations are normally more diaphragmatic than thoracic.

- When checking for proper blood pressure cuff size, which guideline is correct? a. The standard cuff size is appropriate for all sizes. b. The length of the rubber bladder should equal 80% of the arm circumference. c. The width of the rubber bladder should equal 80% of the arm circumference. d. The width of the rubber bladder should equal 40% of the arm circumference. ANS: D The width of the rubber bladder should equal 40% of the circumference of the person's arm. The length of the bladder should equal 80% of this circumference.
