HESI Pharmacology Practice Exam

Correct Answer: C

Rationale: Naloxone hydrochloride is an antidote to opioids and may be administered to postoperative clients to address respiratory depression. This medication can also reverse the effects of analgesics, potentially leading to a sudden increase in pain. Therefore, the nurse must assess the client for any unexpected rise in pain levels after naloxone administration.

Correct Answer: C

Rationale: Furosemide (Lasix) is a diuretic that can lead to orthostatic hypotension, causing dizziness. Instructing the client to change positions slowly can help prevent this adverse effect. It is important for the client to consume foods rich in potassium to prevent hypokalemia. Taking furosemide in the morning helps reduce the need for frequent urination at night. Encouraging the client to maintain an adequate fluid intake is crucial to prevent dehydration while on this medication.

Correct Answer: B

Rationale: The nurse should instruct the client to report a pulse rate less than 60 beats per minute, as it could indicate digoxin toxicity. Consuming potassium-rich foods is encouraged due to the potential for furosemide (Lasix) to cause hypokalemia. The medications should be taken in the morning to prevent nocturia. Additionally, the client should weigh themselves daily to monitor for fluid retention, which is crucial in managing heart failure.

Correct Answer: C

Rationale: The nurse should instruct the client to apply the nitroglycerin (Nitro-Dur) transdermal patch at the same time each day to ensure consistent blood levels. It is essential to apply the patch to a hairless area of the skin for proper absorption. The patch can generally be left on during a shower. The patch is usually worn for 12-14 hours to allow for a nitrate-free period, which helps reduce tolerance to the medication.

Correct Answer: D

Rationale: The therapeutic effect of docusate sodium (Colace) is to soften stools and promote regular bowel movements, making option D the correct choice. Monitoring for regular bowel movements would indicate that the medication is working as intended by relieving or preventing constipation. Options A, B, and C are not directly related to the therapeutic effect of docusate sodium.
