1. A client has a prescription for Bethanechol to treat urinary retention. Which of the following findings is a manifestation of muscarinic stimulation?
- A. Dry mouth
- B. Hypertension
- C. Excessive perspiration
- D. Fecal impaction
Correct answer: C
Rationale: The correct answer is C: Excessive perspiration. Bethanechol is a muscarinic agonist that stimulates muscarinic receptors. Activation of muscarinic receptors can lead to excessive perspiration (diaphoresis) due to increased cholinergic activity, affecting sweat glands. Dry mouth, hypertension, and fecal impaction are not typically associated with muscarinic stimulation. Dry mouth is more commonly associated with anticholinergic medications, hypertension can be a result of alpha-adrenergic stimulation, and fecal impaction is not a direct effect of muscarinic receptor activation.
2. During a unit of whole blood transfusion, a client develops a cough, shortness of breath, elevated blood pressure, and distended neck veins. The healthcare professional should anticipate a prescription for which of the following medications?
- A. Epinephrine
- B. Lorazepam
- C. Furosemide
- D. Diphenhydramine
Correct answer: C
Rationale: In the scenario described, the client is exhibiting signs of fluid overload, which can occur during blood transfusion. Furosemide, a loop diuretic, is commonly prescribed in such situations to help relieve manifestations of circulatory overload by promoting diuresis and reducing fluid volume. Therefore, the correct choice is C - Furosemide. Epinephrine (Choice A) is not indicated for fluid overload but for severe allergic reactions. Lorazepam (Choice B) is a benzodiazepine used for anxiety or sedation, not for fluid overload. Diphenhydramine (Choice D) is an antihistamine often used for allergic reactions, not for fluid overload.
3. A client has a new prescription for Levothyroxine. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Take this medication at bedtime.
- C. Take this medication on an empty stomach.
- D. Take this medication with antacids.
Correct answer: C
Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption. By taking Levothyroxine on an empty stomach, the client ensures optimal absorption and effectiveness of the medication.
4. A client is starting a new prescription for enalapril. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Rise slowly from a sitting position.
- C. Avoid salt substitutes.
- D. Avoid exposure to sunlight.
Correct answer: C
Rationale: The correct instruction for a client starting enalapril is to avoid salt substitutes. Salt substitutes may contain potassium, which could lead to elevated potassium levels when combined with enalapril, increasing the risk of hyperkalemia. Choices A, B, and D are incorrect because there is no specific need to take enalapril with food, rise slowly from a sitting position, or avoid exposure to sunlight when taking this medication.
5. When teaching a client with a new prescription for Lithium, which instruction should the nurse include?
- A. Restrict fluid intake to 1,000 mL per day.
- B. Maintain a consistent sodium intake.
- C. Take the medication at bedtime.
- D. Expect to have frequent headaches.
Correct answer: B
Rationale: Maintaining a consistent sodium intake is crucial when taking Lithium to help regulate lithium levels in the body and prevent toxicity. Sodium levels can impact the effectiveness and safety of Lithium therapy. Restricting fluid intake to 1,000 mL per day (Choice A) is not appropriate and could lead to dehydration. Taking the medication at bedtime (Choice C) may vary depending on the individual's schedule but is not a critical instruction. Expecting to have frequent headaches (Choice D) is not a common side effect of Lithium.
