Nursing Elites

1. Why is the specific gravity for infants lower than for older children?

• A. Infants have a greater body surface area.
• B. Infants have a higher basal metabolic rate.
• C. Infants have a greater percentage of body weight that is water.
• D. Infants' kidneys are less able to concentrate urine.

Correct answer: D

Rationale: The correct answer is D because infants' kidneys are less developed compared to older children, making them less efficient at concentrating urine. This results in a lower specific gravity in infants. The other choices do not directly explain why the specific gravity is lower in infants.

2. Which assessment finding, after the dialysate is drained during peritoneal dialysis for a child experiencing acute renal failure, would warrant further action by the nurse?

• A. The dialysate is clear upon return.
• B. The volume of drained dialysate is less than the volume infused.
• C. The child is restless and eager to play.
• D. The child's vital signs remain consistent with those noted during infusion.

Correct answer: B

Rationale: A lower volume of drained dialysate compared to the volume infused suggests a possible obstruction or malfunction in the dialysis process. This finding could compromise the effectiveness of the treatment and needs prompt assessment and intervention by the nurse to ensure the child's safety and well-being. Choices A, C, and D are not indicative of complications during peritoneal dialysis. The clarity of the dialysate, the child's behavior, and the consistency of vital signs are not alarming findings that would require immediate action by the nurse.

3. During a vaso-occlusive crisis in sickle cell anemia, what action is crucial for a nurse to take?

• A. Administer meperidine for pain.
• B. Apply cold compresses to the child's joints.
• C. Limit the child's fluid intake.
• D. Maintain bed rest for the child.

Correct answer: D

Rationale: During a vaso-occlusive crisis in sickle cell anemia, maintaining bed rest is crucial to reduce oxygen consumption and alleviate pain. Movement can worsen the crisis by increasing sickling of red blood cells, leading to further tissue damage and pain. Bed rest helps to improve blood flow, reduce pain, and promote healing. Administering meperidine for pain (Choice A) is not recommended due to the risk of normeperidine accumulation and potential neurotoxicity. Applying cold compresses (Choice B) may cause vasoconstriction, worsening the vaso-occlusive crisis. Limiting fluid intake (Choice C) is not appropriate as adequate hydration is essential to prevent dehydration and maintain blood flow.

4. What is the goal of pharmacologic therapy in the treatment of Parkinson�s disease?

• A. To increase the amount of acetylcholine at the pre-synaptic neurons
• B. To reduce the amount of dopamine available in the substantia nigra
• C. To balance cholinergic and dopaminergic activity in the brain
• D. To block dopamine receptors in pre-synaptic and post-synaptic neurons

Correct answer: C

Rationale: Parkinson�s disease results from a decrease in dopaminergic (inhibitory) activity, leaving an imbalance with too much cholinergic (excitatory) activity. With an increase in dopamine, the neurotransmitter activity becomes more balanced, and symptoms are controlled.

5. A nurse is providing teaching to the guardian of an infant about home safety. Which of the following statements by the guardian indicates an understanding of the teaching?

• A. I will place my baby on her stomach to sleep
• B. I will put a small pillow in my baby's crib
• C. I will keep my baby's crib away from the radiator
• D. I will use a drop-side crib for my baby

Correct answer: C

Rationale: The nurse should instruct the guardian to keep the baby�s crib away from the radiator to prevent burns.
