HESI RN 301 Pharmacology Final Exam Questions
Extract:
Question 1 of 5
A male client tells the home health nurse that he has started taking magnesium hydroxide and aluminum hydroxide to treat occasional heartburn. It is most important for the nurse to review the client's medical history regarding the presence of which disorder?
Correct Answer: C
Rationale: Magnesium and aluminum hydroxide are excreted renally, and renal disease can lead to accumulation, causing toxicity. Diabetes, thrombosis, and bronchitis are less directly affected.
Question 2 of 5
The healthcare provider prescribes the antibiotic tetracycline HCl for an adult client that arrived at an outpatient clinic. Which instruction should the nurse include in the teaching plan for this client?
Correct Answer: A
Rationale: Tetracycline increases photosensitivity, requiring sun protection. Orange juice, milk, and antacids reduce absorption, and weekly serum levels aren’t typically needed.
Question 3 of 5
Prior to administering oral doses of calcitriol and calcium carbonate to a client with hypoparathyroidism, the nurse notes that the client's total calcium level is 14 mg/dl (3.5 mmol/l). Which action should the nurse implement?
Correct Answer: D
Rationale: A calcium level of 14 mg/dL indicates hypercalcemia, risking toxicity. Both calcitriol and calcium carbonate increase calcium levels, so holding both and contacting the provider is safest.
Question 4 of 5
The nurse is assessing the eyes of a client who just received mydriatic eye drops. Which physiological function of the eye will not respond during the therapeutic period after administration of the eye drops?
Correct Answer: B
Rationale: Mydriatic drops dilate pupils, inhibiting constriction during their effect. Accommodation, refraction, and convergence may be indirectly affected but remain functional.
Question 5 of 5
A client who is a vegetarian has a new prescription for warfarin. The client reports eating leafy green vegetables every day. How should the nurse respond?
Correct Answer: A
Rationale: Leafy greens, high in vitamin K, can reduce warfarin’s effectiveness. The provider needs to know to adjust dosing. Replacing greens, claiming enhanced efficacy, or encouraging unchanged habits are incorrect.
