A nurse is reviewing the medical record of a client who has schizophrenia and is taking clozapine.
Which of the following findings should the nurse identify as a contraindication to the administration of clozapine?
Heart rate 58/min.
Fasting blood glucose 100 mg/dL.
WBC count 2,900/mm3.
Hgb 14 g/dL.
The Correct Answer is C
Choice A rationale:
Heart rate 58/min. Clozapine, an atypical antipsychotic medication, can cause bradycardia (slow heart rate) as a side effect. However, the heart rate of 58/min is within the normal range for adults, so it is not a contraindication for clozapine administration.
Choice B rationale:
Fasting blood glucose 100 mg/dL. A fasting blood glucose level of 100 mg/dL is within the normal range (70-99 mg/dL) for adults. It is not a contraindication for clozapine administration.
Choice C rationale:
WBC count 2,900/mm3. Clozapine can cause agranulocytosis, a severe reduction in white blood cell (WBC) count, which can lead to increased susceptibility to infections. A WBC count of 2,900/mm3 is significantly below the normal range (4,000-11,000/mm3) and is a contraindication for clozapine administration due to the risk of severe immunosuppression.
Choice D rationale:
Hgb 14 g/dL. Hemoglobin (Hgb) level of 14 g/dL is within the normal range for adult males (13.8-17.2 g/dL) and females (12.1-15.1 g/dL). It is not a contraindication for clozapine administration.

Correct Answer is D
Explanation
Choice A rationale:
Give the client protamine if signs of magnesium sulfate toxicity occur. Protamine is not the antidote for magnesium sulfate toxicity. Calcium gluconate or calcium chloride is used to counteract the effects of magnesium sulfate toxicity by antagonizing the action of magnesium on the neuromuscular junction and the heart.
Choice B rationale:
Monitor the FHR via Doppler every 30 min. While fetal heart rate (FHR) monitoring is important during magnesium sulfate infusion due to the risk of fetal distress, using Doppler every 30 minutes may not provide continuous and accurate monitoring. Continuous electronic fetal monitoring is the standard of care in this situation.
Choice C rationale:
Restrict the client's total fluid intake to 250 mL/hr. Magnesium sulfate is excreted by the kidneys, so maintaining adequate urine output is crucial to prevent magnesium toxicity. Restricting fluid intake to 250 mL/hr would likely reduce urine output, leading to an increased risk of magnesium sulfate accumulation in the body, which could be harmful.
Choice D rationale:
Measure the client's urine output every hour. Monitoring urine output is essential during magnesium sulfate infusion as it helps assess renal function and magnesium excretion. Adequate urine output (at least 30 mL/hr) is necessary to prevent magnesium toxicity. Therefore, measuring the client's urine output every hour is a critical nursing intervention to ensure the safety of the client.
Correct Answer is D
Explanation
Choice A rationale:
An altered level of consciousness is a common finding in clients with Alzheimer's disease. This may range from mild confusion to severe cognitive impairment. It is caused by the degeneration of brain cells and affects memory, thinking, and behavior.
Choice B rationale:
Rapid mood swings are not specific to Alzheimer's disease. While mood changes can occur, they are not typically characterized by rapid swings. Mood disturbances may include depression, apathy, or irritability, but these symptoms are not unique to Alzheimer's disease.
Choice C rationale:
Excessive motor activity is not a typical finding in clients with Alzheimer's disease. Instead, clients often experience a decline in motor skills and coordination as the disease progresses. Restlessness or agitation might occur, but excessive motor activity is not a characteristic feature.
Choice D rationale:
Failure to recognize familiar objects, people, or places is a common symptom of Alzheimer's disease. This is due to the damage and loss of nerve cells in the brain. As the disease advances, clients may have difficulty recognizing even close family members or their own reflection in the mirror.
