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

• A. Height
• B. Weight
• C. Skinfold thickness
• D. Upper arm circumference

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. Which clinical manifestations should the nurse anticipate when assessing a child for hypoglycemia?

• A. Lethargy
• B. Thirst
• C. Nausea and vomiting
• D. Shaky feeling and dizziness

Correct answer: D

Rationale: The correct answer is D: 'Shaky feeling and dizziness.' Hypoglycemia in children often presents with symptoms like shakiness, dizziness, sweating, hunger, and irritability. These symptoms occur because the brain and body are deprived of the glucose they need to function properly. Choices A, B, and C are incorrect because lethargy, thirst, nausea, and vomiting are not typically primary manifestations of hypoglycemia in children.

3. When teaching a mother how to administer eye drops, where should the nurse tell her to place them?

• A. At the lacrimal duct
• B. On the sclera while the child looks to the outside
• C. In the conjunctival sac when the lower eyelid is pulled down
• D. Carefully under the eyelid while it is gently pulled upward

Correct answer: C

Rationale: Eye drops should be placed in the conjunctival sac, which allows the medication to be absorbed properly without causing irritation. Placing drops directly on the sclera or near the lacrimal duct is less effective and can cause discomfort.

4. A 13-year-old boy comes to the school nurse complaining of sudden and severe scrotal pain. He denies any trauma to the scrotum. What is the most appropriate nursing action?

• A. Refer him for immediate medical evaluation
• B. Administer analgesics and recommend scrotal support.
• C. Apply an ice bag and observe for increasing pain.
• D. Reassure the adolescent that occasional pain is common with the changes of puberty.

Correct answer: A

Rationale: Sudden and severe scrotal pain in an adolescent male is a medical emergency and may indicate testicular torsion, which requires immediate evaluation and intervention to prevent testicular loss.

5. A child has a central venous access device for intravenous (IV) fluid administration. A blood sample is needed for a complete blood count, hemogram, and electrolytes. What is the appropriate procedure to implement for this blood sample?

• A. Perform a new venipuncture to obtain the blood sample.
• B. Interrupt the IV fluid and withdraw the blood sample needed.
• C. Withdraw a blood sample equal to the amount of fluid in the device, discard, and then withdraw the sample needed.
• D. Flush the line and central venous device with saline and then aspirate the required amount of blood for the sample.

Correct answer: C

Rationale: Withdrawing and discarding a sample equal to the amount of fluid in the device ensures that the blood drawn is not diluted by the IV fluids, providing accurate lab results.
