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 ["A","C","D","E","F","G"]
Explanation
The correct answers are Choices A, C, D, E, F, and G.
Choice A rationale: Antihypertensive medication is indicated due to sustained elevated BP (≥160/110 mm Hg), which increases risk for stroke, placental abruption, and eclampsia. Prompt control reduces maternal and fetal morbidity.
Choice B rationale: Routine vaginal exams are contraindicated unless signs of labor are present. Frequent exams increase infection risk and are not part of standard care for hypertensive or preeclamptic clients.
Choice C rationale: A low-stimulation environment (dim lights, quiet room) reduces CNS irritability and seizure risk in preeclampsia. It supports neuroprotection and aligns with seizure precaution protocols.
Choice D rationale: Betamethasone promotes fetal lung maturity in preterm gestation when delivery is likely. It reduces neonatal respiratory distress syndrome and improves outcomes in hypertensive pregnancies.
Choice E rationale: A 24-hour urine specimen quantifies proteinuria, essential for diagnosing preeclampsia severity. Protein 3+ on dipstick warrants confirmation via timed collection for accurate staging.
Choice F rationale: Hourly intake and output monitoring detects fluid shifts, renal compromise, and early signs of pulmonary edema. It’s critical in hypertensive disorders to guide fluid management.
Choice G rationale: Bed rest minimizes physical stress, stabilizes BP, and reduces risk of placental disruption. Left lateral positioning enhances uteroplacental perfusion and supports fetal oxygenation.
Correct Answer is B
Explanation
The correct answer is Choice B.
Choice A rationale: Maintaining bed elevation at 20 degrees is not recommended. The recommended bed elevation for patients receiving enteral tube feedings is at least 30 to 45 degrees.This is to prevent aspiration of the feeding solution into the lungs.
Choice B rationale: Flushing the tubing with 30 mL of water every 4 hours is a recommended practice.This helps to maintain the patency of the feeding tube and prevent clogging.
Choice C rationale: Checking for gastric residual every 12 hours is not sufficient.For patients receiving continuous tube feedings, gastric residual volume (GRV) should be monitored every 4 hours.This helps to assess tolerance to the feeding and prevent complications such as aspiration.
Choice D rationale: Placing enough formula in the container to last 18 hours is not recommended.For an open system, the formula should be replaced every 4 hours to prevent bacterial growth.
