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?

Correct Answer: A

Rationale: A WBC count of 2,900/mm3 indicates leukopenia, which is a serious side effect of clozapine and contraindicates its use. Leukopenia is a significant concern with clozapine therapy due to the risk of agranulocytosis, a potentially life-threatening condition. Monitoring the WBC count is crucial to detect this adverse effect early. The other options (B, C, and D) are within normal ranges and not contraindications for administering clozapine.

Correct Answer: B

Rationale: The correct answer is to check the client's capillary blood glucose level every 4 hours. Clients receiving TPN are at risk for hyperglycemia, so regular monitoring of blood glucose levels is essential to detect and manage hyperglycemia promptly. Administering TPN through a peripheral IV catheter (Choice A) is incorrect as TPN should be given through a central venous catheter to prevent complications. Heating the TPN solution to room temperature (Choice C) is unnecessary and not a standard practice. Weighing the client every 3 days (Choice D) is important for monitoring fluid status but is not the priority action when caring for a client receiving TPN.

Correct Answer: C

Rationale: The correct answer is C: Hyponatremia. In SIADH, there is excessive release of antidiuretic hormone, causing water retention and dilutional hyponatremia. Polyuria (choice A) is increased urination, which is not a typical finding in SIADH. Dehydration (choice B) is the loss of body fluids, which is opposite to the fluid retention seen in SIADH. Hyperglycemia (choice D) is elevated blood sugar levels and is not directly related to SIADH.

Correct Answer: D

Rationale: The correct answer is D. A platelet count of 100,000/mm³ is low and increases the risk of bleeding during the bronchoscopy. This finding should be reported to the provider for further evaluation and possible intervention. Choices A, B, and C are not as critical in this situation. Anxiety about the procedure is common and can be managed with appropriate interventions. Not eating for 8 hours is a standard pre-procedure requirement to prevent aspiration during sedation. A reported allergy to shellfish is important to note but is not directly related to the risk of complications during a bronchoscopy.
