1. 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.

2. The child is admitted to the hospital unit newly diagnosed with retinoblastoma. Which clinical manifestation does the nurse anticipate upon assessment?

Correct answer: A

Rationale: The correct answer is A: A white reflex. The 'white reflex' or leukocoria is a common sign of retinoblastoma. It occurs when the light reflects off the tumor in the eye, giving the pupil a white appearance instead of the normal red reflex. Blue-tinged sclerae (choice B) and yellow-tinged sclerae (choice D) are not typical manifestations of retinoblastoma. A red reflex (choice C) is the normal reflection seen in the eye when light is shone on it and is not associated with retinoblastoma.

3. A mother has just given birth to a newborn with a cleft lip. Sensing that something is wrong, she starts to cry and asks the nurse, "What is wrong with my baby?" What is the most appropriate nursing action?

Correct answer: A

Rationale: Encouraging the mother to express her feelings allows her to process the situation and prepares her for receiving further information in a supportive environment.

4. A child with acetylsalicylic acid (aspirin) poisoning is being admitted to the emergency department. What early clinical manifestation does the nurse expect to assess on this child?

Correct answer: D

Rationale: Early signs of aspirin poisoning include hyperventilation due to the stimulation of the respiratory center and the resultant respiratory alkalosis. Hematemesis, hematochezia, and hyperglycemia can occur later in the poisoning process or may not be directly related to aspirin toxicity.

5. A nurse is evaluating the effectiveness of teaching regarding care of a child with minimal change nephrotic syndrome (MCNS) that is in remission after administration of prednisone. The nurse realizes further teaching is required if the parents state what?

Correct answer: D

Rationale: Children with MCNS in remission can usually return to school. Home schooling may be necessary only if there are complications. The other options show an understanding of proper care during remission.
