Correct Answer: A

Rationale: Crepitus (grating or crunching sound) with joint movement is a common finding in osteoarthritis due to cartilage degeneration and bone-on-bone contact.
Choice B is incorrect because osteoarthritis typically causes asymmetrical joint swelling, unlike rheumatoid arthritis, which is symmetrical.
Choice C is incorrect because morning stiffness in osteoarthritis is brief (less than 30 minutes), unlike rheumatoid arthritis, where it lasts longer (e.g., 2 hours).
Choice D is incorrect because fever is not a feature of osteoarthritis unless there is an infection or another condition.

Correct Answer: A

Rationale: Monitoring for signs of serotonin syndrome (e.g., agitation, tremors, hyperthermia) is critical with fluoxetine, an SSRI, as it increases serotonin levels, and overdose or drug interactions can cause this life-threatening condition.
Choice B is incorrect because fluoxetine is typically taken in the morning, as it can cause insomnia if taken at bedtime.
Choice C is incorrect because fluoxetine is more likely to cause weight loss or be weight-neutral in bulimia, not weight gain.
Choice D is incorrect because fluoxetine should not be discontinued abruptly, even if binge eating stops, as this can cause withdrawal symptoms or relapse; it requires provider guidance.

Correct Answer: C

Rationale: Crackles in bilateral lung bases indicate fluid accumulation or infection in the lungs, a concerning finding in pneumonia that may suggest worsening condition or complications like pulmonary edema, requiring immediate reporting.
Choice A is incorrect because an oxygen saturation of 92% is borderline but not immediately alarming in pneumonia, especially if the client is receiving oxygen; it should be monitored.
Choice B is incorrect because a respiratory rate of 24/min is slightly elevated but expected in pneumonia and not the priority to report.
Choice D is incorrect because a temperature of 37.8°C is a low-grade fever, common in pneumonia, and does not require immediate reporting unless persistent or accompanied by other symptoms.

Correct Answer: D

Rationale: A spinal cord injury at the C5 level typically preserves the function of the diaphragm (innervated by C3-C5) and shoulder muscles (deltoid and rotator cuff, innervated by C5), allowing the client to shrug shoulders.
Choice A is incorrect because a C5 injury affects the lower extremities, causing paraplegia or quadriplegia, depending on the extent.
Choice B is incorrect because, while respiratory function is partially preserved (diaphragm intact), the client may still have impaired accessory muscle function, leading to reduced respiratory capacity.
Choice C is incorrect because sensation loss typically occurs below the level of injury (below C5), not necessarily below the clavicles, and may vary in completeness.

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.
