A nurse is assessing a client who has hypermagnesemia. Which of the following medications should the nurse prepare to administer?
Flumazenil
Acetylcysteine
Calcium gluconate
Protamine sulfate
The Correct Answer is C
Choice A rationale: Flumazenil is a benzodiazepine receptor antagonist used for benzodiazepine overdose, not hypermagnesemia.
Choice B rationale: Acetylcysteine is used in acetaminophen overdose, not for hypermagnesemia.
Choice C rationale: Calcium gluconate is often used to counteract the effects of hypermagnesemia by antagonizing the actions of excess magnesium.
Choice D rationale: Protamine sulfate is used to reverse the effects of heparin, not for hypermagnesemia.

Correct Answer is A
Explanation
Choice A rationale: Citalopram is a selective serotonin reuptake inhibitor (SSRI) that increases the level of serotonin in the brain. Serotonin syndrome is a rare but serious adverse effect of SSRIs that can cause confusion, agitation, tremors, seizures, and coma. The nurse should report this finding to the provider immediately, as it can be life-threatening.
Choice B rationale: Insomnia can occur as an adverse effect of citalopram but might not be as immediately concerning as confusion.
Choice C rationale: Bruxism (teeth grinding) can be a side effect of citalopram but might not pose an immediate risk compared to confusion.
Choice D rationale: Weight loss, while a potential side effect, might not be as urgent or immediately concerning as confusion.
Correct Answer is D
Explanation
Choice A rationale: Exophthalmos (bulging eyes) is a characteristic feature of Graves' disease and might not directly relate to the need for a lower medication dose.
Choice B rationale: Weight loss is a symptom of hyperthyroidism and might not directly indicate the need for a lower methimazole dose.
Choice C rationale: Diaphoresis (excessive sweating) can be a symptom of hyperthyroidism but might not solely indicate the need for a lower methimazole dose.
Choice D rationale: Bradycardia (abnormally slow heart rate) might indicate excessive suppression of thyroid function caused by an excessive dose of methimazole in a client with Graves' disease, warranting a lower medication dose.
