1. A client with a diagnosis of generalized anxiety disorder is prescribed fluvoxamine. The nurse should instruct the client that this medication may have which potential side effect?
- A. Drowsiness
- B. Dry mouth
- C. Insomnia
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Drowsiness. Fluvoxamine is known to cause drowsiness as a potential side effect. Patients should be advised to avoid activities like driving that require alertness until they understand how the medication affects them. Dry mouth, insomnia, and headache are potential side effects of other medications used for anxiety disorders but are not typically associated with fluvoxamine.
2. 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.
3. A client has been diagnosed with open-angle glaucoma. The healthcare provider prescribes pilocarpine 1% eye drops. The nurse explains that which action of this drug makes it a useful treatment for the client's condition?
- A. The ciliary muscle contracts, increasing the outflow of aqueous humor in the eye.
- B. Ciliary muscles are paralyzed to decrease accommodation.
- C. Bilateral mydriasis with cycloplegia is accomplished.
- D. The production of aqueous humor in the eyes is decreased.
Correct answer: A
Rationale: Pilocarpine, a cholinergic agent, stimulates the ciliary muscle to contract, which opens the trabecular meshwork and facilitates the outflow of aqueous humor, reducing intraocular pressure. This mechanism helps in managing open-angle glaucoma by improving drainage and lowering pressure within the eye. Choice A is correct because the contraction of the ciliary muscle increases the outflow of aqueous humor, aiding in the treatment of open-angle glaucoma. Choices B, C, and D are incorrect because they do not describe the mechanism of action of pilocarpine in treating glaucoma.
4. What class of laxative would the nurse recommend to a patient asking about the best way to prevent constipation?
- A. Stimulant laxatives
- B. Bulk-forming laxatives
- C. Emollient laxatives
- D. Hyperosmotic laxatives
Correct answer: B
Rationale: The correct answer is B: Bulk-forming laxatives. These laxatives are recommended to prevent constipation because they work by absorbing liquid in the intestines, forming a bulky, soft stool that is easier to pass. They are safe and considered the most natural option. Stimulant laxatives (choice A) work by promoting bowel movements through intestinal contractions and are more suitable for treating occasional constipation rather than preventing it. Emollient laxatives (choice C) soften the stool by increasing the incorporation of water into the feces and are more suitable for patients who need to avoid straining during defecation. Hyperosmotic laxatives (choice D) work by drawing water into the intestine through osmosis and are typically used for more severe cases of constipation, not for prevention.
5. A client is prescribed atorvastatin. The practical nurse should monitor the client for which potential adverse effect?
- A. Muscle pain and weakness
- B. Headache
- C. Hepatotoxicity
- D. Gastrointestinal bleeding
Correct answer: A
Rationale: The correct answer is A: Muscle pain and weakness. Atorvastatin is known to potentially cause muscle pain and weakness, which could indicate muscle damage or rhabdomyolysis. This adverse effect should be closely monitored by the practical nurse to ensure early detection and appropriate management. Choices B, C, and D are incorrect because they are not typically associated with atorvastatin use. Headache is a less common side effect, hepatotoxicity is rare but serious, and gastrointestinal bleeding is not a common adverse effect of atorvastatin.
