1. Which is the most frequently used test for measuring visual acuity?

Correct answer: A

Rationale: The Snellen letter chart is the most commonly used test for measuring visual acuity, particularly in school-age children and adults.

2. The clinic nurse is assessing a child with a heavy ascariasis lumbricoides (common roundworm) infection. Which assessment findings should the nurse expect?

Correct answer: D

Rationale: A heavy roundworm infection can cause anemia, anorexia, irritability, and an enlarged abdomen due to the worms’ effects on nutrient absorption and intestinal function.

3. The nurse is testing an infant's visual acuity. By which age should the infant be able to fix on and follow a target?

Correct answer: C

Rationale: By 3 to 4 months of age, an infant should be able to fix on and follow a target, indicating proper visual development.

4. What is the first step in managing a child with anaphylaxis?

Correct answer: C

Rationale: The correct answer is to administer epinephrine. Administering epinephrine is the crucial first step in managing anaphylaxis as it helps reverse the severe allergic reaction by constricting blood vessels and relaxing airway muscles, preventing a life-threatening situation. Antihistamines (Choice A) are not the first-line treatment for anaphylaxis and should not delay the administration of epinephrine. Establishing IV access (Choice B) may be necessary but is not the initial step in managing anaphylaxis. Monitoring vital signs (Choice D) is important but should not take precedence over administering epinephrine in the acute management of anaphylaxis.

5. Which parameter correlates best with measurements of total muscle mass?

Correct answer: D

Rationale: Upper arm circumference correlates best with total muscle mass because it includes both muscle and fat components, making it a reliable indicator of muscle mass.
