A nurse is educating a client at the end of her second trimester about car safety.
Which statement by the client indicates a correct understanding of the nurse's education?

Choice A rationale

Methotrexate is used for treating ectopic pregnancies and certain cancers, but it is not an antidote for Magnesium Sulfate toxicity.

Choice B rationale

Labetalol is a beta-blocker used for hypertension management in pregnancy, not for reversing Magnesium Sulfate toxicity.

Choice C rationale

Nifedipine is a calcium channel blocker used to manage high blood pressure and preterm labor, not for counteracting Magnesium Sulfate toxicity.

Choice D rationale

Calcium gluconate is the specific antidote for Magnesium Sulfate toxicity, effectively reversing its effects.

Given the symptoms and physical examination findings, the nurse should anticipate a provider prescription for Acyclovir as evidenced by the presence of vesicles and pustules.

The case presented shows several key indicators that point toward a diagnosis of genital herpes, which is caused by the herpes simplex virus (HSV).

1. Presence of vesicles and pustules: The small, pinpoint open vesicles and pustules on the labia majora, along with clear drainage, are classic signs of genital herpes.
2. Erythema and tenderness: The redness (erythema) and tenderness of the perineal area further support this diagnosis.
3. Systemic symptoms: The client reports muscle aches and chills, which are common systemic symptoms of a viral infection like herpes.
4. Denies dysuria and other severe symptoms: The absence of symptoms like dysuria and acute distress is consistent with the presentation of genital herpes during the vesicle stage.

Acyclovir is an antiviral medication commonly prescribed for the treatment of herpes simplex infections. It helps to reduce the severity and duration of symptoms. Hence, the nurse should anticipate a prescription for Acyclovir based on the clinical presentation and findings.
