Question 1 of 5
Which of these specific measurements is the best index of a child's general health?
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.
Question 2 of 5
A child is admitted to the hospital several days after stepping on a sharp object that punctured her athletic shoe and entered the flesh of her foot. The physician is concerned about osteomyelitis and has ordered parenteral antibiotics. Which of the following actions is done immediately before the antibiotic is started?
Correct Answer: B
Rationale: Before starting antibiotics, a blood culture should be drawn to identify the causative organism. This step is crucial as antibiotics may interfere with the identification process. Drawing a complete blood count with differential or writing admission orders are important steps in patient care but are not as critical as obtaining a blood culture to guide appropriate antibiotic therapy. The arrival of the parents is not directly related to the immediate action required before starting antibiotics in this scenario.

Question 4 of 5
Why should a palpated pressure be performed before auscultating blood pressure?
Correct Answer: B
Rationale: Performing a palpated pressure before auscultating blood pressure helps in detecting the presence of an auscultatory gap. An auscultatory gap is a period during blood pressure measurement when Korotkoff sounds temporarily disappear before reappearing. Inflation of the cuff 20 to 30 mm Hg beyond the point where a palpated pulse disappears helps in identifying this gap. This technique ensures accurate blood pressure measurement by preventing the underestimation of blood pressure values. The other options are incorrect because palpating the pressure is not primarily done to hear Korotkoff sounds more clearly, avoid missing falsely elevated blood pressure, or readily identify a specific phase of Korotkoff sounds.
Question 5 of 5
A patient is seen in the clinic for reports of "fainting episodes that started last week."? How would the nurse proceed with the examination?
Correct Answer: C
Rationale: When a patient reports fainting episodes, it is crucial to assess for orthostatic hypotension. If the nurse suspects volume depletion, the patient has hypertension, is on antihypertensive medications, or has a history of fainting or syncope, blood pressure readings should be taken in three positions: lying, sitting, and standing. This assessment helps detect orthostatic hypotension, which can provide valuable information about the patient's condition. Taking blood pressure readings in multiple positions allows for a comprehensive evaluation of possible postural changes in blood pressure.
Choices A, B, and D are incorrect because they do not cover the necessary positions to assess for orthostatic hypotension effectively.
