Correct Answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. This medication helps dilate the blood vessels, reducing the workload of the heart and improving blood flow to the heart muscle, which is crucial in the management of acute coronary syndrome. Checking cardiac enzymes (choice B) is important for diagnosing a heart attack but is not the priority over providing immediate relief to the patient's chest pain. Administering aspirin (choice C) is also important in acute coronary syndrome to prevent further clot formation, but it is not the priority action for immediate pain relief. Obtaining IV access (choice D) is necessary for administering medications or fluids; however, in this scenario, providing sublingual nitroglycerin for prompt pain relief takes precedence.

Correct Answer: A

Rationale: The correct answer is to monitor serum albumin levels. In patients with diabetes insipidus, monitoring serum albumin levels is essential to assess for dehydration and nutritional deficits. Choices B, C, and D are not directly related to managing diabetes insipidus. Restricting protein intake, encouraging fluid intake, and teaching the patient to avoid alcohol are interventions that may be relevant for other medical conditions but are not specific to addressing the needs of a patient with diabetes insipidus.

Correct Answer: A

Rationale: When caring for a patient with an air leak in the chest tube system, the nurse should tighten the connections of the chest tube system. This action can help resolve the air leak by ensuring there are no loose connections or leaks in the system. Continuing to monitor the patient (Choice B) is important, but addressing the air leak is a priority. Replacing the chest tube system (Choice C) may not be necessary if tightening the connections resolves the issue. Clamping the chest tube (Choice D) is not appropriate as it can lead to tension pneumothorax.

Correct Answer: A

Rationale: The correct answer is A: Albuterol via nebulizer. Albuterol is a rapid-acting bronchodilator that helps relieve wheezing by opening up the airways. During an allergic reaction causing wheezing, prompt relief is crucial, making Albuterol the first-line treatment. Choice B, Cromolyn via nebulizer, is used more for preventing asthma symptoms rather than providing immediate relief. Choice C, Aminophylline IV, is a bronchodilator with a slower onset of action compared to Albuterol. Choice D, Methylprednisolone IV, is a corticosteroid used to reduce inflammation and is not the first-line treatment for acute wheezing in an allergic reaction.

Correct Answer: A

Rationale: The correct recommendation for a patient with GERD is to avoid mint and spicy foods. Mint and spicy foods can aggravate GERD symptoms by relaxing the lower esophageal sphincter and increasing stomach acid production, leading to acid reflux. Choices B, C, and D are incorrect. Eating large meals before bedtime can worsen GERD symptoms as lying down can promote acid reflux. Consuming liquids with meals can also exacerbate GERD by increasing stomach distension and pressure on the lower esophageal sphincter. Eating three large meals per day can overload the stomach and trigger acid reflux episodes in patients with GERD.
