A nurse is planning care for a child during admission to the facility.

Which of the following actions should the nurse take first?

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.

Choice A rationale:

Recent myocardial infarction is not a contraindication for warfarin administration. Warfarin is often prescribed for patients with a history of myocardial infarction to prevent clot formation and reduce the risk of stroke.

Choice B rationale:

Recent eye surgery is a contraindication for the administration of warfarin. Warfarin can increase the risk of bleeding, which is particularly concerning after eye surgery due to the delicate nature of ocular tissues. Using anticoagulants in this scenario can lead to severe complications, including vision loss.

Choice C rationale:

Thrombophlebitis, inflammation of a vein with clot formation, is not a contraindication for warfarin administration. In fact, anticoagulants like warfarin are commonly prescribed to prevent the extension of clots and reduce the risk of complications associated with thrombophlebitis.

Choice D rationale:

Breast cancer is not a direct contraindication for warfarin administration. However, the decision to use anticoagulants in patients with a history of breast cancer should be made carefully, considering individual factors such as the stage of cancer, ongoing treatment, and overall risk of thromboembolic events.
