1. 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.

2. When a patient with a history of chronic obstructive pulmonary disease (COPD) is prescribed ipratropium, the nurse should monitor for potential side effects. The correct answer is dry mouth. Ipratropium can cause dry mouth as a common side effect due to its anticholinergic effects. This side effect can impact the patient's oral health and comfort, requiring close monitoring and appropriate interventions.

A. Dry mouth
B. Tachycardia
C. Insomnia
D. Increased appetite

Correct answer: A

Rationale: Ipratropium is an anticholinergic medication commonly used in COPD. One of the most common side effects of anticholinergics is dry mouth due to the inhibition of salivary gland function. Tachycardia (Choice B) is not a typical side effect of ipratropium. Insomnia (Choice C) is also not a common side effect of this medication. Increased appetite (Choice D) is not associated with ipratropium use. Therefore, the correct side effect to monitor for in a patient prescribed ipratropium is dry mouth.

3. A client with osteoporosis is prescribed alendronate. The practical nurse (PN) should reinforce which instruction regarding the administration of this medication?

A. Take the medication with a full glass of water before breakfast.
B. Take the medication immediately after a meal.
C. Lie down for 30 minutes after taking the medication.
D. Crush the medication and mix it with food.

Correct answer: A

Rationale: The correct instruction for administering alendronate is to take the medication with a full glass of water before breakfast. This timing is crucial to ensure proper absorption in the body and reduce the risk of esophageal irritation. Taking it immediately after a meal or lying down for 30 minutes after may affect absorption and increase the risk of adverse effects. It should not be crushed or mixed with food to maintain its effectiveness.

4. A client with diabetes mellitus type 2 is prescribed glipizide. 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 hypoglycemia to the healthcare provider.

Correct answer: A

Rationale: The correct instruction for a client prescribed glipizide, a sulfonylurea used to lower blood sugar levels, is to take the medication with meals. Taking it with meals helps to minimize the risk of hypoglycemia by ensuring a more balanced effect on blood glucose levels throughout the day. It is important for the client to follow this instruction to maintain stable blood sugar levels and reduce the likelihood of experiencing low blood sugar (hypoglycemia) episodes. Choice B is incorrect because there are no specific contraindications between glipizide and alcohol. Choice C is incorrect as glipizide should not be taken on an empty stomach. Choice D is incorrect as while it is important to report signs of hypoglycemia, the primary focus should be on preventing hypoglycemia by taking the medication with meals.

5. When a client with hypertension is prescribed losartan, what potential side effect should the nurse monitor for?

A. Hyperkalemia
B. Dry cough
C. Bradycardia
D. Headache

Correct answer: B

Rationale: The correct answer is B: Dry cough. Losartan, an angiotensin II receptor blocker, can lead to a dry cough as a potential side effect. This occurs due to the drug's effect on the bradykinin pathway in the lungs. Monitoring for a dry cough is essential as it may indicate the need for further evaluation or medication adjustment to manage this adverse reaction.
