Correct Answer: C

Rationale: Monitoring for muscle weakness, which may indicate hypokalemia, is critical, as furosemide is a loop diuretic that can cause potassium loss, increasing the risk of arrhythmias in heart failure clients.
Choice A is wrong because clients with heart failure should limit sodium intake to reduce fluid retention, not increase it, to prevent exacerbation of heart failure.
Choice B is wrong because taking furosemide at bedtime is not advised; it should be taken in the morning to avoid nocturia and disrupted sleep due to its diuretic effect.
Choice D is wrong because increasing fluid intake is not recommended for heart failure clients, as it can worsen fluid overload; fluid intake should be guided by the provider based on the client's condition.

Correct Answer: A

Rationale: Flashbacks of the traumatic event are a hallmark symptom of PTSD, where clients vividly re-experience the trauma, leading to significant distress.
Choice B is incorrect because euphoria is not associated with PTSD; clients typically experience anxiety, depression, or hypervigilance.
Choice C is incorrect because PTSD often causes insomnia or nightmares, not an increased need for sleep.
Choice D is incorrect because weight gain is not a primary feature; weight changes may occur secondary to depression or medication side effects.

Correct Answer: B

Rationale: Full-thickness tissue loss with visible muscle is characteristic of a stage 3 or 4 pressure ulcer, indicating severe tissue damage common in advanced pressure ulcers.
Choice A is incorrect because erythema and intact skin describe a stage 1 pressure ulcer, not a fully developed one.
Choice C is incorrect because blanchable redness over a bony prominence indicates tissue at risk but not yet a pressure ulcer.
Choice D is incorrect because eschar may be present in unstageable pressure ulcers, but full-thickness loss with visible muscle is a more specific finding for stage 3 or 4.

Correct Answer: C

Rationale:
Choice A is wrong because it is not a typical symptom of bacterial pneumonia. Drooling can be caused by other conditions, such as sore throat, dental problems, or neurological disorders.
Choice B is wrong because it is not a symptom of bacterial pneumonia either. Tinnitus is a ringing or buzzing sound in the ears that can be caused by exposure to loud noise, ear infections, or other ear problems. Malaise is a general feeling of discomfort, weakness, or illness that can be a sign of infection. According to the health search result from Focus Medica, bacterial pneumonia is an infection of the air sacs in one or both lungs that causes symptoms such as cough with phlegm, fever, chills, and difficulty breathing. Malaise is one of the symptoms that may follow these signs of infection.
Choice D is wrong because it is not specific to bacterial pneumonia. Rhinorrhea is a runny nose that can be caused by many factors, such as allergies, colds, or sinus infections. Rhinorrhea can sometimes occur with viral pneumonia, but not usually with bacterial pneumonia.

Correct Answer: C

Rationale: Monitoring for dizziness or drowsiness is important with buspirone, a non-benzodiazepine anxiolytic, as these are common side effects that may affect safety or require dose adjustment.
Choice A is incorrect because buspirone is taken regularly (2-3 times daily), not as needed, to achieve steady-state anxiety control.
Choice B is incorrect because buspirone takes 2-4 weeks to provide significant anxiety relief, not immediate relief.
Choice D is incorrect because buspirone should not be discontinued abruptly, even if symptoms resolve, to avoid withdrawal or relapse; it requires provider guidance.
