Nursing Elites

1. 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.

2. Following a child's return from exploratory surgery due to a gunshot wound to the abdomen, which nursing intervention should be excluded from the plan of care?

• A. Immediate initiation of oral feedings
• B. Assessment of the surgical site
• C. Administration of opioid narcotics for pain management
• D. Visitation at the bedside

Correct answer: A

Rationale: Immediate initiation of oral feedings should be excluded from the plan of care post-abdominal surgery due to the risk of bowel complications like paralytic ileus or anastomotic leak. Starting oral feedings immediately can increase these risks and hinder healing. It is crucial to wait until bowel function returns and the patient shows signs of tolerance before introducing oral feedings. Assessment of the surgical site is necessary to monitor for any signs of infection or complications. Administration of opioid narcotics for pain management is essential for ensuring the patient's comfort post-surgery. Visitation at the bedside provides emotional support and can aid in the patient's recovery. Therefore, the correct answer is to exclude immediate initiation of oral feedings.

3. The healthcare provider is caring for a 9-month-old infant who just returned from the postanesthesia care unit (PACU) after a shunt placement for hydrocephalus. Which healthcare provider prescription should the nurse question?

• A. Vital signs and neurologic checks hourly
• B. Small, frequent formula feedings
• C. Elevate the head of the bed
• D. Daily head circumference measurements

Correct answer: C

Rationale: Elevating the head of the bed in a child with hydrocephalus can potentially increase intracranial pressure. This can be counterproductive and may lead to complications after shunt placement surgery. Keeping the head of the bed flat or slightly elevated is often recommended to optimize cerebral perfusion and reduce the risk of increased intracranial pressure.

4. The nurse is expecting the admission of a child with severe isotonic dehydration. Which intravenous fluid prescription does the nurse anticipate for this child?

• A. 0.9% normal saline (NS)
• B. D5 0.2% (�) normal saline
• C. D5W
• D. Albumin

Correct answer: A

Rationale: Isotonic dehydration requires the administration of normal saline to restore fluid balance.

5. A patient in the emergency department reports taking sildenafil (Viagra) and nitroglycerin 1 hr before sexual activity. Which finding should the nurse immediately report to the physician?

• A. WBC of 3200 cells/mm³
• B. RR of 26 breaths/min
• C. Temp of 38°C
• D. BP of 70/50

Correct answer: D

Rationale: The correct answer is D: BP of 70/50. When sildenafil (Viagra) is taken with nitroglycerin, it can cause severe hypotension that is unresponsive to treatment. The combination of these medications can lead to a dangerous drop in blood pressure. It is crucial to immediately report hypotension in this scenario as it poses a significant risk to the patient's life. It is recommended to allow at least 24 hours to elapse between the last dose of sildenafil and nitroglycerin to prevent such adverse effects. The other vital signs and lab values may be abnormal but do not have the immediate life-threatening implications that severe hypotension does in this context.
