Correct Answer: A

Rationale: An elevated antinuclear antibody (AN
A) titer is a hallmark finding in systemic lupus erythematosus, present in over 95% of clients, indicating autoimmune activity.
Choice B is incorrect because the erythrocyte sedimentation rate (ESR) is typically elevated in SLE due to inflammation, not decreased.
Choice C is incorrect because complement levels (C3, C4) are often decreased in SLE due to immune complex formation, not normal.
Choice D is incorrect because rheumatoid factor may be positive in some SLE clients, but it is not specific to SLE and is more associated with rheumatoid arthritis.

Correct Answer: C

Rationale: Rapid speech is typical in a manic episode of bipolar disorder. Hypersomnia, weight gain, and flat affect are more associated with depression.

Correct Answer: A

Rationale: A respiratory rate of 10/min is below the normal range (12-20/min) and indicates potential magnesium sulfate toxicity, which can lead to respiratory depression or arrest. This finding should be reported immediately to the provider, and the infusion may need to be stopped.
Choice B is wrong because a blood pressure of 150/90 mm Hg, while elevated, is not unexpected in preeclampsia and does not indicate immediate toxicity; it should be monitored, but it is not the priority.
Choice C is wrong because a urine output of 40 mL/hr is within the acceptable range (at least 30 mL/hr) for a client receiving magnesium sulfate and does not indicate renal compromise.
Choice D is wrong because deep tendon reflexes of 2+ are normal and do not suggest magnesium toxicity, which would present with absent or diminished reflexes.

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: 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.
