HESI Pharmacology Practice Exam Questions
Question 1 of 5
A client is learning how to mix regular insulin and NPH insulin in the same syringe. Which action, if performed by the client, indicates the need for further teaching?
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.
Question 2 of 5
Before initiating a client with tuberculosis on anti-tuberculosis therapy with isoniazid (INH), a nurse ensures that which of the following baseline studies has been completed?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
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.
Question 4 of 5
When administering hydrochlorothiazide (HydroDIURIL) to a client, the nurse should be aware of which of the following concerns?
Correct Answer: C
Rationale: The correct answer is C. Hydrochlorothiazide is a thiazide diuretic, which can lead to hypokalemia, hyperglycemia, hypercalcemia, hyperlipidemia, and hyperuricemia. It is a sulfa-based medication, so individuals with a sulfa allergy are at risk for an allergic reaction when taking hydrochlorothiazide.
Question 5 of 5
Nalidixic acid (NegGram) is prescribed for a client with a urinary tract infection. On review of the client's record, the nurse notes that the client is taking warfarin sodium (Coumadin) daily. Which prescription should the nurse anticipate for this client?
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.
