Nursing Elites

1. 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.

2. Kimberly is having a checkup before starting kindergarten. The nurse asks her to do the “finger-to-nose test.” What is the purpose of this test?

• A. Deep tendon reflexes
• B. Cerebellar function
• C. Sensory discrimination
• D. Ability to follow directions

Correct answer: B

Rationale: The finger-to-nose test assesses cerebellar function, which is responsible for balance and coordination. The test evaluates how well the cerebellum controls motor functions and coordination. Choice A, deep tendon reflexes, is incorrect because this test does not assess reflexes but rather cerebellar function. Choice C, sensory discrimination, is incorrect as this test focuses on motor function rather than sensory abilities. Choice D, ability to follow directions, is incorrect since the test primarily assesses motor coordination and not cognitive skills related to following instructions.

3. What is the first sign of puberty in boys?

• A. Enlargement of testes
• B. Decreased levels of testosterone
• C. Voice deepening
• D. Pubic hair

Correct answer: A

Rationale: The first sign of puberty in boys is typically the enlargement of the testes. This is due to the increase in production of testosterone, which leads to physical changes such as growth of the testes. Choice B, decreased levels of testosterone, is incorrect as puberty is marked by an increase in testosterone levels. Choice C, voice deepening, and choice D, pubic hair growth, usually occur later in the puberty process compared to testicular enlargement, making them incorrect answers.

4. What is an important intervention in providing a neutral thermal environment for an LBW infant in an incubator?

• A. Use wool blankets.
• B. Avoid using disposable diapers.
• C. Prevent heat loss.
• D. Closely monitor both incubator and rectal temperatures.

Correct answer: C

Rationale: Preventing heat loss in a low birth weight (LBW) infant is crucial in maintaining a neutral thermal environment. The use of cotton blankets is recommended over wool blankets. Avoiding disposable diapers is not directly related to maintaining a neutral thermal environment. While monitoring temperatures is important, the key intervention is preventing heat loss to ensure the infant's survival.

5. Examination of the abdomen is performed correctly by the nurse in which order?

• A. Inspection, palpation, percussion, and auscultation
• B. Inspection, percussion, auscultation, and palpation
• C. Palpation, percussion, auscultation, and inspection
• D. Inspection, auscultation, percussion, and palpation

Correct answer: D

Rationale: The correct order for abdominal examination is inspection, auscult
