1. A client with type 2 diabetes is prescribed metformin. What instruction should the practical nurse (PN) include in the client's teaching plan?
- A. Take the medication with meals to decrease gastrointestinal upset.
- B. Take the medication with a full glass of water.
- C. Avoid alcohol while taking the medication.
- D. Take the medication with meals to increase absorption.
Correct answer: B
Rationale: The correct instruction for a client prescribed metformin is to take the medication with a full glass of water. This helps ensure proper ingestion and absorption of the medication. While taking metformin with meals can help reduce gastrointestinal side effects, the primary focus should be on adequate hydration and absorption by taking it with water. Avoiding alcohol while taking metformin is also important as alcohol can increase the risk of lactic acidosis when combined with metformin. Taking the medication with meals to increase absorption is incorrect as metformin should be taken with food to reduce gastrointestinal upset, not to increase absorption.
2. A client with chronic heart failure is prescribed furosemide. The nurse should monitor the client for which potential adverse effect?
- A. Increased blood glucose levels
- B. Electrolyte imbalance
- C. Dehydration
- D. Weight gain
Correct answer: C
Rationale: When a client with chronic heart failure is prescribed furosemide, a diuretic, the nurse should be vigilant for potential adverse effects. Furosemide can lead to excessive fluid loss, resulting in dehydration. Dehydration is a significant concern as it can exacerbate heart failure symptoms. Additionally, furosemide can cause electrolyte imbalances, particularly affecting potassium and sodium levels. Monitoring for signs of dehydration and electrolyte disturbances is crucial to prevent complications and ensure the client's safety and well-being. Increased blood glucose levels and weight gain are not commonly associated with furosemide use in heart failure patients, making choices A and D incorrect.
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. A client with chronic kidney disease is prescribed darbepoetin alfa. The nurse should monitor for which potential side effect?
- A. Hypertension
- B. Hypotension
- C. Hyperkalemia
- D. Hyperglycemia
Correct answer: A
Rationale: The correct answer is A: Hypertension. Darbepoetin alfa, used to treat anemia in chronic kidney disease, can lead to hypertension as a side effect. This medication stimulates red blood cell production, which can increase blood pressure. Monitoring blood pressure regularly is crucial to detect and manage this potential adverse effect. Choices B, C, and D are incorrect because hypotension, hyperkalemia, and hyperglycemia are not commonly associated with darbepoetin alfa therapy in chronic kidney disease.
5. A client who is prescribed sildenafil for pulmonary hypertension calls the clinic for advice. Which condition should the practical nurse notify the health care provider immediately and instruct the client to stop taking the medication?
- A. The client is experiencing vision and hearing loss.
- B. The client has an erection lasting longer than 4 hours.
- C. The client is complaining of nasal congestion.
- D. The client is complaining of feeling flushed.
Correct answer: A
Rationale: The correct answer is A. If a client prescribed sildenafil for pulmonary hypertension experiences vision and/or hearing loss or an erection lasting more than 4 hours, the practical nurse should instruct the client to discontinue the medication immediately and notify the health care provider. These symptoms could indicate serious side effects that require prompt medical attention to prevent complications. Choices B, C, and D are incorrect because an erection lasting more than 2 hours (not 4 hours as stated in choice B) is a critical adverse effect that warrants immediate medical attention. Nasal congestion (choice C) and feeling flushed (choice D) are common side effects of sildenafil and typically do not necessitate immediate discontinuation of the medication or emergency intervention.
