HESI Practice Test Pharmacology Questions
Question 1 of 5
A client prescribed glipizide asked why they had to take their insulin orally. How should the practical nurse respond?
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.
Question 2 of 5
While a client is receiving the medication haloperidol, which client data would indicate to the practical nurse that the medication is therapeutic?
Correct Answer: B
Rationale: When a client is taking haloperidol, a therapeutic response involves a decrease in symptoms such as paranoia, hallucinations, delusions, and emotional excitement. These improvements indicate that the medication is effectively managing the client's condition. Monitoring for a reduction in paranoid behaviors helps the practical nurse assess the medication's effectiveness in addressing the client's psychiatric symptoms.
Question 3 of 5
A client with bipolar disorder is taking lithium. Which client assessment data would indicate a potential adverse effect of lithium therapy?
Correct Answer: B
Rationale: When assessing a client taking lithium, dry mouth and increased thirst are indicators of potential adverse effects. Lithium can lead to nephrogenic diabetes insipidus, causing polyuria and subsequent increased thirst due to impaired water reabsorption in the kidneys. Tremors can also be a sign of lithium toxicity. Monitoring and recognizing these symptoms are crucial in managing lithium therapy and preventing further complications.
Question 4 of 5
A client is prescribed clopidogrel. The nurse should monitor for which potential side effect of this medication?
Correct Answer: C
Rationale: When a client is prescribed clopidogrel, the nurse should monitor for potential side effects related to bleeding due to its antiplatelet effect. Gastrointestinal bleeding is a severe side effect associated with clopidogrel use. Monitoring for signs of gastrointestinal bleeding, such as black, tarry stools or vomiting blood, is essential to prevent serious complications.
