The nurse is instructing a patient who will take psyllium (Metamucil) to treat constipation.
What information will the nurse include when teaching this patient?
The need to monitor for systemic side effects.
The need to use the dry form of Metamucil to prevent cramping.
The importance of consuming adequate amounts of water.
The onset of action of 30 to 60 minutes after administration.
The Correct Answer is C
The correct answer is c. The importance of consuming adequate amounts of water.
Rationale for Choice A:
- Statement: The need to monitor for systemic side effects.
- Rationale: It's not accurate to prioritize monitoring for systemic side effects when teaching a patient about psyllium (Metamucil). Psyllium is a bulk-forming laxative that primarily acts within the gastrointestinal tract, and systemic side effects are rare. While it's essential to be aware of potential side effects, focusing on them during initial teaching might cause unnecessary anxiety.
Rationale for Choice B:
- Statement: The need to use the dry form of Metamucil to prevent cramping.
- Rationale: This statement is incorrect. It's generally recommended to mix psyllium with water or another liquid before ingestion. Consuming the dry form can increase the risk of choking and might not adequately hydrate stool.
Rationale for Choice C:
- Statement: The importance of consuming adequate amounts of water.
- Rationale: This is the most crucial information to emphasize when teaching about psyllium. Psyllium works by absorbing water and forming a bulky gel that softens stool and promotes bowel movements. Without sufficient water intake, psyllium can cause constipation to worsen or lead to intestinal obstruction.
Rationale for Choice D:
- Statement: The onset of action of 30 to 60 minutes after administration.
- Rationale: This statement is inaccurate. Psyllium is not a fast-acting laxative. It typically takes 12-72 hours to produce a bowel movement. Informing patients about the expected time frame for results is essential to manage expectations and prevent unnecessary medication overuse.

Correct Answer is A
Explanation
800 mg PO at bedtime is an appropriate dosage and frequency of cimetidine for the treatment of gastric ulcer. Cimetidine is a histamine H antagonist that reduces the secretion of gastric acid.
Choice B is wrong because 150 mg PO b.i.d. is too low of a dose for cimetidine. The usual adult dose for duodenal ulcer is 800 mg PO once a day at bedtime or 300 mg PO four times a day.
Choice C is wrong because 20 mg PO b.i.d. is not a valid dose for cimetidine.
The lowest available tablet strength is 100 mg.
Choice D is wrong because 300 mg PO at bedtime is also too low of a dose for cimetidine.
The usual adult dose for gastric ulcer is 800 mg PO once a day at bedtime or 300 mg PO four times a day.
Correct Answer is A
Explanation
The nurse should ask this question because the client is taking a chemical stimulant laxative, which can cause dehydration and electrolyte imbalance, especially in combination with medications for heart failure and osteoarthritis that may also affect fluid and electrolyte balance. The nurse should assess the client’s hydration status and risk of hypovolemia or hypotension.
Choice B. Timing of medication administration is wrong because it is not the priority question in this situation.
The nurse should ask this question later to determine if the client is taking the medications as prescribed and if there are any drug interactions or adverse effects.
Choice C. Previous effectiveness of laxatives is wrong because it is not relevant to the client’s current condition.
The nurse should ask this question later to evaluate the client’s bowel habits and history of constipation.
Choice D. The amount of fiber intake is wrong because it is not the priority question in this situation.
The nurse should ask this question later to educate the client about dietary measures to prevent constipation and promote bowel health.
