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.

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.
In which of these patients would rectal temperatures be measured?
- A. Older adult
- B. Critically ill patient
- C. School-age child
- D. Patient receiving oxygen via nasal cannula
Correct Answer: B
Rationale: Rectal temperature measurement is preferred in situations where other routes are impractical or when the most accurate measure is necessary, such as in critically ill patients. The rectal route may be chosen due to its reliability in such cases. For older adults, school-age children, and patients receiving oxygen via nasal cannula, rectal temperature measurement is not typically indicated. Other routes like oral, tympanic, or axillary measurements are more commonly used in these populations due to comfort, convenience, and non-invasive nature.
While measuring a patient's blood pressure, which factor influences a patient's blood pressure?
- A. Pulse rate
- B. Pulse pressure
- C. Vascular output
- D. Peripheral vascular resistance
Correct Answer: D
Rationale: When measuring a patient's blood pressure, it is important to consider various factors that influence blood pressure. Peripheral vascular resistance plays a crucial role in regulating blood pressure. The level of blood pressure is affected by factors such as cardiac output, peripheral vascular resistance, volume of circulating blood, viscosity, and elasticity of the vessel walls. Pulse rate (Choice A) refers to the number of heartbeats per minute and is not a primary factor influencing blood pressure. Pulse pressure (Choice B) is the difference between systolic and diastolic blood pressure and does not directly impact blood pressure regulation. Vascular output (Choice C) is not a recognized term in blood pressure regulation and is not a primary factor affecting blood pressure.
The nurse is assessing an 80-year-old male patient. Which assessment finding would be considered normal?
- A. Decrease in body weight from his younger years
- B. Decrease in deposits of fat in the cheeks and forearms
- C. Presence of kyphosis and flexion in bilateral knees and hips
- D. Change in overall body proportion, including a longer trunk and shorter extremities
Correct Answer: C
Rationale: In an 80-year-old male patient, the presence of kyphosis (rounded upper back) and flexion in bilateral knees and hips are considered normal age-related changes. These postural changes are commonly seen in older adults due to structural changes in the spine and joints. Option A is incorrect as aging individuals typically experience a decrease in body weight, not an increase. Option B is also incorrect as there is usually a decrease in subcutaneous fat from the face and periphery, rather than an increase in fat deposits in specific areas. Option D is incorrect because the change in overall body proportion with aging usually involves a shorter trunk and relatively longer extremities, not the other way around. This is because long bones do not shorten with age, leading to this characteristic change in body proportions.
A 60-year-old patient has been treated for pneumonia for the past 6 weeks. The patient is seen today in the clinic for an unexplained weight loss of 10 pounds over the last 6 weeks. Which is an appropriate rationale for this patient's weight loss?
- A. Chronic diseases such as hypertension do not usually cause weight loss.
- B. Weight loss is more likely due to underlying medical conditions than unhealthy eating habits.
- C. Unexplained weight loss often accompanies short-term illnesses.
- D. Weight loss is not typically caused by mental health dysfunctions.
Correct Answer: C
Rationale: Unexplained weight loss in a patient with pneumonia could indicate an underlying short-term illness or a chronic condition like endocrine disease, malignancy, depression, anorexia nervosa, or bulimia. Hypertension is not commonly associated with weight loss; it usually leads to weight gain due to fluid retention. Unhealthy eating habits are less likely to explain significant unexplained weight loss over a short period. Mental health dysfunctions can affect appetite but are not typically primary causes of significant unexplained weight loss.
