Four days after exposure to the coronavirus (COVID-19), a client has a negative COVID-19 test result.

Eight days after the negative test result, the client presents with fever, fatigue, and cough, and the nurse performs a second COVID-19 test.

Which action is most important for the nurse to take?

The correct answer is Choice C

Choice A rationale: This question prematurely assumes the client is experiencing command hallucinations, which are auditory hallucinations instructing the individual to perform specific actions, often dangerous. Scientifically, this bypasses the essential diagnostic step of characterizing the hallucination type. Without understanding onset, frequency, and context, asking about obedience risks escalating paranoia or defensiveness. Psychiatric assessment requires chronological and phenomenological data before evaluating risk. Prematurely probing intent may compromise rapport and hinder accurate clinical evaluation.

Choice B rationale: While substance-induced psychosis is a differential diagnosis, asking about hallucinogen use before establishing the nature and onset of symptoms may be perceived as accusatory. Scientifically, the DSM-5 criteria for substance-induced psychotic disorder require temporal correlation between substance use and symptom onset. Without knowing when the voices began, this question lacks diagnostic precision. A thorough psychiatric history must precede substance screening to avoid bias and ensure accurate etiological classification of hallucinations.

Choice C rationale: Establishing the onset of auditory hallucinations is foundational in psychiatric assessment. Scientifically, the timeline helps differentiate between transient, substance-induced, and chronic psychotic disorders such as schizophrenia. Early onset may suggest prodromal schizophrenia, while abrupt onset could indicate delirium or drug-induced psychosis. Understanding duration also informs risk stratification and treatment planning. This question respects clinical sequencing, allowing the nurse to gather essential data before exploring content, belief, or behavioral response to hallucinations.

Choice D rationale: Exploring the client’s belief about the reality of voices is part of assessing insight, but it should follow initial characterization of the hallucinations. Scientifically, insight evaluation helps determine the severity of psychosis and guides treatment adherence predictions. However, asking this prematurely may confuse or distress the client. Insight is typically assessed after establishing symptom chronology, frequency, and impact. Premature probing of belief risks misinterpretation and may hinder therapeutic engagement in early assessment stages.

Choice A rationale:

Diarrhea and flatulence are common side effects of statin medications like lovastatin but are typically not considered emergencies. They may be managed with dietary adjustments or over-the-counter remedies.

Choice B rationale:

Muscle pain, especially if severe, requires the most immediate follow-up by the nurse. Muscle pain can be a symptom of a rare but serious side effect called rhabdomyolysis, which can lead to muscle breakdown and potential kidney damage. Prompt assessment and intervention are necessary if severe muscle pain occurs.

Choice C rationale:

Altered taste is a side effect of lovastatin but is generally not considered a medical emergency. It may affect the client's quality of life but does not require immediate follow-up.

Choice D rationale:

Abdominal cramps may occur as a side effect of lovastatin, but they are not typically considered an emergency. Like choice A, abdominal cramps can often be managed with dietary adjustments or over-the-counter remedies.
