A nurse is providing teaching to a client following surgery to repair a detached retina of the left eye. Which of the following instructions should the nurse include in the teaching?

Rationale:
A. "Your child can return to school 24 hours after beginning antibiotics.": Varicella (chickenpox) is a viral infection, so antibiotics are not effective unless there is a secondary bacterial infection.

B. "Your child can return to school once the fever has subsided.": Although the fever may resolve, the child remains contagious until all lesions have crusted over, so returning at this stage risks spreading infection.

C. "Your child can return to school after a negative titer result.": Titer testing is used to assess immunity, not for determining when an active infection is no longer contagious.

D. "Your child can return to school once the lesions have crusted over.": This is the correct statement because a child with varicella is contagious until all vesicular lesions have dried and crusted, usually about 5–7 days after onset.

Rationale for Correct Choices:

• Serotonin syndrome: The client’s symptoms recent SSRI dose increase indicate possible serotonin toxicity. Serotonin syndrome occurs when excessive serotonin accumulates in the body, typically following dose escalation or interaction between serotonergic medications. It is a medical emergency that can progress to seizures or death if not promptly identified and treated.

• Adverse effects of paroxetine: The increase in paroxetine dosage one week prior likely triggered excessive serotonergic activity. Paroxetine, an SSRI, elevates serotonin levels, and dose escalation can precipitate serotonin syndrome.

Rationale for Incorrect Choices:

• Generalized anxiety disorder: Although the client has a history of anxiety, the acute onset of fever, disorientation, and autonomic instability points to a physiological reaction rather than worsening anxiety. Anxiety may cause restlessness but does not produce hyperthermia or confusion.

• Neuroleptic malignant syndrome: This condition is associated with antipsychotic drugs, not SSRIs like paroxetine. While both syndromes can present with fever and altered mental status, the client’s medication profile and timing support serotonin toxicity instead.

• Feelings of hopelessness: Although ongoing hopelessness is part of the client’s depression, it does not explain the acute physical manifestations. Emotional symptoms may persist with depression, but fever and disorientation indicate a pharmacologic rather than psychological cause.

• Anxiety: Anxiety alone cannot account for the client’s fever, disorientation, or abdominal pain. These findings suggest a systemic reaction consistent with serotonin excess, not a purely psychological state.
