Pharmacology HESI 55 Questions 2023 - Nurselytic

Correct Answer: A

Rationale: The correct answer is A. Ranitidine is prescribed with long-term steroids to reduce the risk of ulcers associated with steroid therapy. Although steroids can increase the risk of ulcers due to their effect on the gastrointestinal system, ranitidine works by reducing stomach acid production, thus helping to prevent ulcer formation.

Choices B, C, and D are incorrect as ranitidine is not given to decrease the risk of infection, reduce blood sugar elevations, or reduce sodium retention associated with steroid usage.

Correct Answer: A

Rationale: The correct answer is A: Cough. Lisinopril is known to cause a persistent dry cough as a side effect. It is essential for the nurse to monitor the client for this adverse reaction as it may lead to discontinuation of the medication. Dizziness, hyperkalemia, and hyponatremia are not typically associated with lisinopril use.

Correct Answer: B

Rationale:
To accurately determine peak and trough levels of vancomycin, blood should be drawn two hours after the completion of the IV dose and 30 minutes before the next dose. This timing allows for appropriate assessment of the drug levels in the body, ensuring accurate monitoring of therapeutic and toxic concentrations.

Correct Answer: B

Rationale: The correct instruction that the practical nurse (PN) should reinforce with a client prescribed nitrate isosorbide dinitrate is to avoid getting up quickly and to rise slowly. Nitrates can cause orthostatic hypotension, a sudden drop in blood pressure when changing positions. By rising slowly, the client can prevent the occurrence of orthostatic hypotension and its associated symptoms.

Correct Answer: C

Rationale: Muscle cramps are a common side effect of furosemide due to its impact on electrolyte levels, especially potassium. Furosemide is a loop diuretic that can lead to potassium depletion, resulting in muscle cramps as one of the manifestations of electrolyte imbalances.
