Pharmacology HESI 2023 Quizlet
1. The nurse is studying antacids that contain magnesium and calcium for the pharmacology exam. The student nurse remembers that these antacids should be used with caution in patients with which condition?
- A. Hypertension
- B. Renal failure
- C. Heart failure
- D. Peptic ulcer disease
Correct answer: B
Rationale: Magnesium and calcium can accumulate in patients with renal failure, leading to toxicity.
2. How does omeprazole work in treating a peptic ulcer?
- A. Increasing the production of gastric acid
- B. Neutralizing stomach acid
- C. Coating the stomach lining
- D. Reducing gastric acid secretion
Correct answer: D
Rationale: Omeprazole is a proton pump inhibitor that works by reducing gastric acid secretion. By inhibiting the enzyme responsible for pumping acid into the stomach, omeprazole helps decrease the acidity level in the stomach, providing relief from peptic ulcers. Option A is incorrect because omeprazole does not increase gastric acid production; instead, it decreases it. Option B is incorrect as omeprazole does not neutralize existing stomach acid but rather reduces its secretion. Option C is incorrect as omeprazole does not coat the stomach lining but acts on reducing acid secretion.
3. A client with diabetes mellitus type 2 is prescribed metformin. What instruction should the nurse include in the client's teaching plan?
- A. Take this medication with meals.
- B. Avoid alcohol while taking this medication.
- C. Take this medication on an empty stomach.
- D. Report any signs of lactic acidosis to the healthcare provider.
Correct answer: A
Rationale: The correct instruction for a client prescribed metformin is to take the medication with meals. Taking metformin with meals helps to minimize gastrointestinal side effects, which are common with this medication. Choice B, avoiding alcohol, is a good practice due to the increased risk of lactic acidosis when alcohol is consumed with metformin; however, it is not the priority teaching point in this scenario. Taking metformin on an empty stomach (Choice C) is incorrect because it can increase the risk of gastrointestinal side effects. Reporting signs of lactic acidosis (Choice D) is important, but it is more related to monitoring for adverse effects rather than a primary teaching point for administration.
4. A client with severe depression is prescribed sertraline. Which statement by the client indicates the need for further teaching?
- A. I can stop taking this medication once I feel better.
- B. It may take 1 to 4 weeks to notice improvement in symptoms.
- C. I should avoid alcohol while taking this medication.
- D. I should take this medication in the morning with food.
Correct answer: A
Rationale: The correct answer is A. Clients should not stop taking sertraline abruptly once they feel better without consulting their healthcare provider. It is important to complete the full course of treatment as prescribed to prevent a relapse of symptoms. Stopping the medication suddenly can lead to withdrawal symptoms and may worsen the condition. Choice B is correct because sertraline may take 1 to 4 weeks to show noticeable improvement in symptoms. Choice C is correct as alcohol should be avoided while taking sertraline due to the increased risk of side effects. Choice D is also correct as taking sertraline in the morning with food can help reduce gastrointestinal side effects.
5. What information should the practical nurse provide to a female client who started taking an oral sulfonamide for a urinary tract infection the previous day and reports slight anorexia, while also experiencing urinary frequency?
- A. Take the medication with an antacid instead of cranberry juice to reduce the anorexia.
- B. Continue to take the medication with a sip of cranberry juice, restricting fluids until the frequency is controlled.
- C. Continue to drink cranberry juice, but take the medicine on an empty stomach with a full glass of water.
- D. Take the medication with a spoonful of ice cream or applesauce and avoid drinking cranberry juice.
Correct answer: C
Rationale: The practical nurse should advise the client to take sulfonamides with a full glass of water to help prevent crystalluria. It is essential to take the medication on an empty stomach, ideally 1 hour before eating or 2 hours after eating to maximize its absorption and effectiveness. Continuing to drink cranberry juice is beneficial, but it is important to take the medicine separately to enhance its therapeutic action.
