Correct Answer: C

Rationale:
Choice A is wrong because checking a STAT cardiac troponin is not the first priority. Cardiac troponin is a biomarker that indicates myocardial injury, but it may not rise until several hours after the onset of chest pain.
Therefore, it is not useful for immediate diagnosis or treatment of acute coronary syndrome.
Choice B is wrong because requesting a prescription for a beta-blocker is not the first priority. Beta-blockers are medications that can lower blood pressure and heart rate, and reduce the oxygen demand of the heart. They can prevent or reduce the recurrence of chest pain and complications of acute coronary syndrome, but they are not indicated for immediate relief of chest pain. Nitroglycerin is a vasodilator that can relieve chest pain caused by myocardial ischemia. The nurse should administer it as soon as possible to improve blood flow to the heart and reduce the risk of myocardial infarction. The nurse should also monitor the client's blood pressure and heart rate after giving nitroglycerin, as it can cause hypotension and reflex tachycardia.
Choice D is wrong because administering oxygen is not the first priority. Oxygen therapy can increase the oxygen supply to the heart and reduce ischemia, but it is not necessary for all clients with chest pain. Oxygen therapy should be based on the client's oxygen saturation level and clinical condition. If the client's oxygen saturation is normal or high, oxygen therapy may not be beneficial and may even be harmful.

Correct Answer: B

Rationale: Monitoring for nausea or dizziness is important with pramipexole, a dopamine agonist, as these are common side effects that may affect safety or require dose adjustment in restless legs syndrome treatment.
Choice A is incorrect because pramipexole is typically taken in the evening or a few hours before bedtime, as symptoms worsen at night.
Choice C is incorrect because pramipexole may take days to weeks to relieve symptoms, not immediately.
Choice D is incorrect because pramipexole should not be discontinued abruptly, even if symptoms resolve, to avoid withdrawal or symptom recurrence; it requires provider guidance.

Correct Answer: B

Rationale: Avoiding direct sunlight is critical while taking ciprofloxacin, a fluoroquinolone, as it can cause photosensitivity, leading to severe sunburn or rash.
Choice A is incorrect because dairy products can reduce ciprofloxacin absorption by binding to the drug; it should be taken 2 hours before or 6 hours after dairy.
Choice C is incorrect because ciprofloxacin tablets should not be crushed, as this can alter their release mechanism; a liquid form is available if swallowing is difficult.
Choice D is incorrect because antacids (containing calcium, magnesium, or aluminum) can decrease ciprofloxacin absorption and should be avoided within 2 hours of the dose.

Correct Answer: D

Rationale: While scheduling nursing staff training for infection control procedures is important, it should not be the first action taken. Before implementing training, it is crucial to identify the factors contributing to the increased infection rates to ensure that the training addresses the specific issues at hand. Meeting with providers to discuss measures to decrease the infections is a necessary step, but it should not be the first action. Providers need to be informed about the situation, but their input will be more valuable once the precipitating factors have been identified. Revising the current policy for catheter care may be necessary, but it should not be the first action. Policies should be based on evidence-based practices and tailored to address the specific issues identified through the investigation. As a charge nurse concerned about a recent increase in facility-acquired catheter infections, the first step should be to identify possible precipitating factors related to the infections. This involves conducting a thorough investigation to determine the root causes of the increased infection rates. By identifying the underlying factors, the nurse can then develop targeted interventions to address the specific issues and prevent further infections.

Correct Answer: A

Rationale: Taking doxycycline with a full glass of water prevents esophageal irritation. Antacids reduce absorption, grapefruit juice is unrelated, and tooth discoloration is a risk in children.
