Correct Answer: D

Rationale: The client's report of pain in a missing limb is consistent with phantom limb pain, which can be distressing. Encouraging the client to discuss his feelings helps address the emotional and psychological aspects of the amputation and supports his overall recovery. Teaching distraction techniques (choice A) may provide temporary relief but does not address the underlying emotional distress. Providing a soft blanket (choice B) is not the priority when dealing with phantom limb pain. Administering pain medication (choice C) may not effectively manage phantom limb pain as it is more related to central nervous system changes rather than tissue damage.

Correct Answer: A

Rationale: In this scenario, the priority action for the nurse is to administer oxygen and elevate the head of the bed. These interventions help relieve dyspnea and chest pain, which can be indicative of a pulmonary embolism or other complications during heparin therapy. Administering nitroglycerin (Choice B) is not the initial priority in this situation as the client's symptoms are not suggestive of angina. Assessing for bleeding (Choice C) is important but not the first action needed to address chest pain and dyspnea. Administering albuterol (Choice D) is not indicated unless there are specific respiratory issues requiring it, which are not described in the scenario.

Correct Answer: B

Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.

Correct Answer: C

Rationale: When a client with rheumatoid arthritis is taking NSAIDs, the nurse should monitor serum creatinine levels. NSAIDs can potentially cause kidney damage, so monitoring creatinine levels helps assess for renal impairment. While monitoring hemoglobin, potassium, and white blood cell count may also be relevant in some cases, serum creatinine is the priority due to the risk of renal complications associated with NSAID use.

Correct Answer: D

Rationale: In this scenario, the patient's periorbital bruising and bloody drainage from both ears suggest a severe head injury. Projectile vomiting is a red flag symptom that may indicate increased intracranial pressure, which requires immediate attention to prevent further neurological deterioration. Rebound abdominal tenderness (choice A) typically indicates peritonitis and is not directly related to the primary head injury. Diminished breath sounds bilaterally (choice B) suggest a pneumothorax or hemothorax, which are important but not as immediately life-threatening in this context. Rib pain with deep inspiration (choice C) is concerning for rib fractures or pulmonary contusion, which are also important but do not take precedence over addressing the potential increased intracranial pressure.
