Nursing Elites

1. As a result of opioid administration, a child's respirations are slow and shallow. Which should the nurse anticipate when assessing the child's arterial blood gas?

• A. Increased PCO2 and respiratory acidosis
• B. Decreased PCO2 and respiratory alkalosis
• C. Low pH and low PCO2
• D. High pH and high PCO2

Correct answer: A

Rationale: When a child's respirations are slow and shallow due to opioid administration, it results in hypoventilation. This leads to retaining carbon dioxide, indicated by an increased PCO2 level on arterial blood gas analysis, and subsequently causes respiratory acidosis due to the buildup of CO2 in the blood. Therefore, choice A, 'Increased PCO2 and respiratory acidosis,' is the correct answer. Choices B, C, and D are incorrect because slow and shallow respirations would not lead to decreased PCO2 or respiratory alkalosis (choice B), low pH and low PCO2 (choice C), or high pH and high PCO2 (choice D).

2. The nurse provides discharge instructions to a patient prescribed verapamil SR 120mg PO daily for HTN. Which statement by the patient indicates understanding of the medication?

• A. �I will take the medication with grapefruit juice each morning.�
• B. �I should expect occasional loose stools from this medication�
• C. �I�ll need to reduce the amount of fiber in my diet�
• D. �I must swallow the pill whole.�

Correct answer: D

Rationale: �SR� indicates that the drug is sustained release; therefore, the patient must swallow the pill intact, without chewing or crushing, which would result in a bolus effect. Grapefruit juice should be avoided, because it can inhibit intestinal and hepatic metabolism of the drug, thereby raising the drug level. Constipation, not loose stools, is a common side effect. Increasing fluids and dietary fiber can help prevent this adverse effect.

3. 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.

4. 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.

5. 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.
