21. a nurse is reviewing a clients prescriptions. the nurse should contact the provider to clarify which of the following prescriptions?: carvedilol 6.25 mg twice daily. Hold for apical pulse less than 50/min.

1.          Final answer:

It is prudent for the nurse to seek clarification on the prescription for regular insulin 5 units subcutaneous due to potential ambiguities in insulin type and patient-specific blood glucose monitoring protocols.

2.          Explanation:

The question refers to the identification of a prescription that may require clarification by a healthcare provider. When reviewing prescriptions, nurses must be aware of indications, dosages, and potential contraindications or requirements for monitoring. The medications listed such as Atorvastatin (a statin), Carvedilol (a beta-blocker), and Captopril (an ACE inhibitor) are all commonly used in clinical practice with well-established dosing and monitoring parameters. Regular insulin is also commonly prescribed, but the prescription provided is potentially ambiguous, as it does not specify the type of regular insulin (e.g., short-acting) or the patient's blood glucose monitoring and adjustment protocols. Therefore, the nurse should contact the provider to clarify the prescription for regular insulin 5 units subcutaneous – such as verifying the type of insulin, if it is indeed short-acting, confirming patient-specific instructions for blood glucose monitoring, and understanding sliding scale adjustments if applicable.
