When taking blood pressures on a variety of people at a health fair, what should the nurse keep in mind?
- A. After menopause, blood pressure readings in women are usually higher 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 are usually higher than those of people who are at a normal weight.
- D. A teenager's blood pressure reading may be lower than that of an adult.
Correct Answer: B
Rationale: When assessing blood pressures, it is important to consider that the blood pressure of African-American adults is typically higher than that of non-Hispanic White adults of the same age. This is significant as Black individuals in the United States have a higher prevalence of hypertension compared to other groups. Blood pressure readings in women are generally higher than in men after menopause. Additionally, blood pressure measurements in overweight individuals are typically higher than those in individuals of normal weight. While teenagers may have lower blood pressure readings than adults, it is crucial to recognize the trend of a gradual rise in blood pressure throughout childhood and into adulthood. Therefore, the correct choice is B. Choices A, C, and D are incorrect as they do not reflect the typical blood pressure differences observed in various populations.

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.
Correct Answer: B
Rationale: The nurse auscultates an apical rate, not a radial pulse, with infants and toddlers. The pulse should be
counted by listening 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 normally more diaphragmatic than thoracic. The nurse should auscultate
an apical heart rate, not palpate a radial pulse, with infants and toddlers.
A second-year nursing student has just suffered a needlestick while working with a patient that is positive for AIDS. Which of the following is the most significant action that the nursing student should take?
- A. Immediately see a social worker
- B. Start prophylactic AZT treatment
- C. Start prophylactic Pentamidine treatment
- D. Seek counseling
Correct Answer: B
Rationale: Starting prophylactic AZT treatment is the most critical intervention in this scenario. Azidothymidine (AZT) is an antiretroviral medication used to prevent and treat HIV/AIDS by reducing the replication of the virus. Post-exposure prophylaxis (PEP) for HIV involves taking medication to suppress the virus and prevent infection after exposure. PEP should be initiated within 72 hours of potential HIV exposure to be effective. Seeking treatment quickly is crucial to enhance its effectiveness. Seeing a social worker (Choice A) may be helpful for emotional support but is not the immediate priority. Pentamidine treatment (Choice C) is not indicated for post-exposure prophylaxis for HIV. Seeking counseling (Choice D) is important for the nursing student's emotional well-being but does not address the urgent need for post-exposure prophylaxis to prevent HIV transmission.
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. 200/92
- B. 200/100
- C. 100/200/92
- D. 200/100/92
Correct Answer: A
Rationale: When auscultating blood pressure, it is crucial to note the points at which Korotkoff sounds change. In adults, the last audible sound indicates the diastolic pressure. In this case, the Korotkoff sounds muffle at 100 mm Hg and disappear at 92 mm Hg. Therefore, the blood pressure should be recorded as systolic/diastolic, which is 200/92. Choices B, C, and D are incorrect because they do not reflect the correct points where the Korotkoff sounds change during blood pressure measurement.
What is the correct action regarding thigh pressure when comparing it to arm pressure in an adolescent with high blood pressure?
- A. The popliteal artery should be auscultated to obtain thigh pressure.
- B. The best position to measure thigh pressure is the prone position.
- C. If the blood pressure in the arm is high in an adolescent, then it should be compared with the thigh pressure.
- D. Thigh pressure is generally higher than arm pressure due to the proximity to the heart and the size of the popliteal vessels.
Correct Answer: C
Rationale: When blood pressure measured in the arm is significantly elevated, especially in adolescents and young adults, it is crucial to compare it with thigh pressure to assess for coarctation of the aorta. The popliteal artery, not the femoral artery, should be auscultated for the thigh pressure reading as the femoral artery is closer to the placement of the blood pressure cuff. Generally, thigh pressure is higher than arm pressure; however, if there is coarctation of the artery, arm pressures can be higher than thigh pressures. The preferred position for measuring thigh pressure is the prone position, not supine, with the knee slightly bent to facilitate accurate readings.
Which of these specific measurements is the best index of a child's general health?
- A. Body mass index
- B. Height and weight
- C. Head circumference
- D. Chest circumference
Correct Answer: B
Rationale: Height and weight are the most accurate measurements to assess a child's general health. These measurements reflect the physical growth and development of the child, indicating overall health status. Choices C and D, head circumference and chest circumference, are important measurements for specific assessments but do not provide as comprehensive an overview of general health as height and weight. Body mass index (BMI) is a calculation based on height and weight, making height and weight more direct and primary indicators of a child's health compared to BMI.
