1. A client is prescribed an antacid for the treatment of peptic ulcer disease. What is the action of this medication that is effective in treating the client's ulcer?
- A. Decrease in the production of gastric secretions
- B. Production of an adherent barrier over the ulcer
- C. Maintenance of a gastric pH of 3.5 or above
- D. Decrease in the gastric motor activity
Correct answer: C
Rationale: The correct answer is C. Antacids work by neutralizing gastric acids and maintaining a gastric pH of 3.5 or above. This pH level is crucial to prevent the activation of pepsinogen, a precursor to pepsin, which can further damage the ulcer. Choice A is incorrect because antacids do not directly decrease the production of gastric secretions; they neutralize existing acid. Choice B is incorrect as antacids do not form a physical barrier over the ulcer but rather neutralize the acid around it. Choice D is also incorrect as antacids do not affect gastric motor activity but focus on reducing acidity in the stomach.
2. A client diagnosed with a sinus infection is prescribed ampicillin sodium. The practical nurse (PN) should instruct the client to notify the healthcare provider immediately if which symptom occurs?
- A. Rash
- B. Nausea
- C. Headache
- D. Dizziness
Correct answer: A
Rationale: The correct answer is A - Rash. Rash is the most common adverse side effect of all generations of penicillin, indicating an allergy to the medication. An allergic reaction could lead to anaphylactic shock, a severe and potentially life-threatening emergency. It is crucial for the client to inform the healthcare provider promptly if a rash develops after taking ampicillin sodium.
3. A client with chronic heart failure is prescribed spironolactone. The nurse should monitor for which potential side effect?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hypernatremia
- D. Hyponatremia
Correct answer: A
Rationale: The correct answer is A: Hyperkalemia. Spironolactone is a potassium-sparing diuretic that can lead to an excess of potassium in the body, resulting in hyperkalemia. This side effect is important to monitor in clients taking spironolactone, especially those with chronic heart failure, as hyperkalemia can lead to serious cardiac complications.
4. A client with a diagnosis of generalized anxiety disorder is prescribed lorazepam. The client should be informed that this medication may have which potential side effect?
- A. Drowsiness
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Drowsiness. Lorazepam, a medication commonly used to treat anxiety disorders, can lead to drowsiness as a common side effect. It is important for clients to be aware of this potential effect, and they should be advised to avoid activities like driving until they understand how the medication affects them. Dry mouth, nausea, and headache are possible side effects of other medications but are less commonly associated with lorazepam.
5. What is important information to provide to a young adult female client planning to become pregnant?
- A. Discontinue this medication one month before.
- B. Breastfeeding is not recommended while.
- C. Baseline liver function results must be obtained.
- D. Do not take multiple vitamins that contradict.
Correct answer: A
Rationale: It is crucial to advise the client to discontinue medication one month before planning to become pregnant to prevent potential harm to the fetus. This precaution is essential as certain medications can have adverse effects on the developing baby. By stopping the medication ahead of time, the client can reduce the risk of any complications during pregnancy.
