Correct Answer: D

Rationale: The correct answer is 'Migraines.' Migraines are not a symptom typically associated with hyperkalemia. In acute hyperkalemia, one would not expect to see migraines. Symptoms of hyperkalemia often include muscle weakness, paresthesias, and cardiac manifestations such as bradycardia or even cardiac arrest. Therefore, choices A, B, and C are more commonly associated with acute hyperkalemia compared to migraines, making it the correct choice.

Correct Answer: D

Rationale: In a patient with pulmonary edema following a myocardial infarction, the nurse should expect symptoms such as air hunger, anxiety, and agitation. Air hunger refers to the feeling of needing to breathe more deeply or more often. Other symptoms of pulmonary edema can include coughing up blood or bloody froth, orthopnea (difficulty breathing when lying down), and paroxysmal nocturnal dyspnea (sudden awakening with shortness of breath). Slow, deep respirations (Choice A) are not typical in pulmonary edema; these patients often exhibit rapid, shallow breathing due to the difficulty in oxygen exchange. Stridor (Choice B) is a high-pitched breathing sound often associated with upper airway obstruction, not typically seen in pulmonary edema. Bradycardia (Choice C), a slow heart rate, is not a characteristic symptom of pulmonary edema, which is more likely to be associated with tachycardia due to the body's compensatory response to hypoxia and increased workload on the heart.

Correct Answer: D

Rationale: Nitro-Dur patch is not associated with photosensitive reactions. It is used to prevent chest pain or angina, and common side effects include headache, lightheadedness, nausea, and flushing. Choices A, B, and C are known to cause photosensitive reactions. Ciprofloxacin (Cipro), Sulfonamides, and Norfloxacin (Noroxin) are drugs that are commonly associated with photosensitivity reactions. Patients taking these medications should be advised to avoid direct sunlight and use sun protection to prevent skin reactions.

Correct Answer: A

Rationale: The correct answer is 'Increased appetite.' In cases of acute meningitis, loss of appetite would be expected rather than an increase. Meningitis is often caused by an infectious agent that colonizes or infects various sites in the body, leading to systemic symptoms. Common symptoms of acute meningitis include fever, vomiting, and poor tolerance of light due to meningeal irritation. The inflammatory response in the meninges can result in symptoms like photophobia. Increased appetite is not typically associated with acute meningitis. Therefore, choice A is the least likely symptom to be observed in a patient with acute meningitis. Choices B, C, and D are symptoms commonly seen in acute meningitis due to the inflammatory process affecting the central nervous system and meninges.

Correct Answer: B

Rationale: While all statements by the client require attention, the most critical one that demands immediate action is option B. Clients who have undergone hip or knee surgery are at an increased risk of postoperative pulmonary embolism. Sudden dyspnea and tachycardia are hallmark signs of this condition. Without appropriate prophylaxis such as anticoagulant therapy, deep vein thrombosis (DVT) can develop within 7 to 14 days after surgery, potentially leading to pulmonary embolism. It is crucial for the nurse to recognize signs of DVT, which include pain, tenderness, skin discoloration, swelling, or tightness in the affected leg. Signs of pulmonary embolism include sudden onset dyspnea, tachycardia, confusion, and pleuritic chest pain. Option B indicates a potentially life-threatening situation that requires immediate intervention to prevent serious complications.
