HESI Pharmacology Practice Exam

Correct Answer: C

Rationale: Heparin is an anticoagulant, so the primary potential complication is bleeding. The healthcare provider should monitor the client for signs of bleeding, such as bruising, hematuria, and gastrointestinal bleeding. Hypertension, tachycardia, and hyperkalemia are not direct complications of heparin therapy.

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.

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: A

Rationale: When mixing regular insulin with another insulin preparation, it is crucial to withdraw the regular insulin first to prevent contamination. NPH insulin should be drawn after the regular insulin to maintain the integrity of each insulin type. Therefore, if the client withdraws the NPH insulin first, it indicates the need for further teaching.

Correct Answer: D

Rationale: Crackles on auscultation of the lungs would indicate a toxic effect related to daunorubicin, known to cause cardiotoxicity. Cardiotoxicity can manifest as heart failure, abnormal ECG findings, or cardiomyopathy. It is crucial for the nurse to monitor for signs of cardiotoxicity to ensure timely intervention and prevent further complications.
