HESI Practice Test Pharmacology

Correct Answer: B

Rationale: In this scenario, the nurse should contact the pharmacy to obtain the correct heparin formulation as the prescription calls for heparin 1,000 units IV STAT. Low molecular weight heparin is not the same as unfractionated heparin, and therefore, the nurse should not administer the available low molecular weight heparin without first obtaining the correct medication. Diluting the available heparin, calculating an equivalent dose, or changing the route of administration would not address the discrepancy between the prescribed heparin and the available low molecular weight heparin.

Correct Answer: A

Rationale: The correct answer is A: Dry cough. Lisinopril, an ACE inhibitor, is known to cause a persistent dry cough as a common side effect. Monitoring for this adverse effect is crucial because it may lead to non-adherence to the medication. Hyperkalemia (choice B) is a potential side effect of potassium-sparing diuretics, not ACE inhibitors like lisinopril. Hypernatremia (choice C) refers to elevated sodium levels and is not a common side effect of lisinopril. Hyponatremia (choice D) is a condition characterized by low sodium levels and is not a typical side effect of lisinopril. Therefore, the nurse should focus on assessing the client for a dry cough when taking lisinopril.

Correct Answer: A

Rationale: The practical nurse should explain to the client that glipizide is not an oral form of insulin but an oral hypoglycemic agent. Glipizide works by enhancing pancreatic production of insulin when some beta cell function is present. It is not a replacement for insulin but helps the body produce more insulin. Therefore, it can be used when there is still some beta cell function present, unlike insulin which is used when there is a deficiency of endogenous insulin production.

Correct Answer: D

Rationale: Levodopa-carbidopa is a medication commonly used in the treatment of Parkinson's disease (PD). It can cause side effects such as hypotension with sudden position changes. To assist the client in managing this side effect, the physical therapy assistant can help avoid sudden position changes. Additionally, if insomnia occurs, adjusting the timing of the last dose earlier in the day can be beneficial. It is important to note that drowsiness can also be a side effect of the medication and should be reported to the nurse. Foods high in Vitamin B6 can interfere with the absorption of levodopa-carbidopa; hence, it is advisable to avoid increasing the consumption of such foods. Lastly, it is crucial to remind the team that while this medication helps alleviate symptoms like tremors, it may not relieve all symptoms of PD comprehensively.

Correct Answer: B

Rationale: When a client is prescribed hydrochlorothiazide, the nurse should monitor for hypokalemia as a potential side effect. Hydrochlorothiazide is a diuretic that can lead to potassium loss, hence monitoring potassium levels is crucial to prevent complications related to hypokalemia.
