Heparin sodium is prescribed for the client. The nurse expects that the healthcare provider will prescribe which of the following to monitor for a therapeutic effect of the medication?

Correct Answer: D

Rationale: The activated partial thromboplastin time (aPTT) is used to monitor the therapeutic effect of heparin sodium. Heparin affects the intrinsic pathway of coagulation, and monitoring aPTT helps ensure the medication is within the therapeutic range to prevent clot formation. Hematocrit and hemoglobin levels assess red blood cell concentrations, while prothrombin time (PT) is used to monitor the therapeutic effect of warfarin sodium, a different anticoagulant that affects the extrinsic pathway of coagulation.

Correct Answer: B

Rationale: Nalidixic acid can intensify the effects of oral anticoagulants by displacing these agents from binding sites on plasma proteins. When an oral anticoagulant, like warfarin sodium (Coumadin), is combined with nalidixic acid, a decrease in the anticoagulant dosage may be necessary to avoid excessive anticoagulation and potential bleeding risks.

Correct Answer: B

Rationale: Bethanechol chloride (Urecholine) should not be administered to clients with urinary strictures as it can contract the bladder and increase pressure within the urinary tract. In individuals with urinary strictures, this elevated pressure may lead to bladder rupture. Therefore, caution is advised when considering the use of Bethanechol chloride in clients with urinary strictures to prevent potential complications.

Correct Answer: A

Rationale: Bethanechol chloride (Urecholine) stimulates muscarinic receptors, which can lead to bradycardia as an adverse effect. Monitoring for bradycardia is crucial when administering this medication. Constipation, hypertension, and dry mouth are not typically associated with the effects of bethanechol chloride.
