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. A client has a new prescription for allopurinol. Which of the following instructions should the nurse include?
- A. Drink 2 liters of water daily.
- B. Avoid taking the medication on an empty stomach.
- C. Limit vitamin C intake while taking this medication.
- D. Take an iron supplement while on this medication.
Correct answer: A
Rationale: The correct instruction for a client prescribed allopurinol is to drink 2 liters of water daily. This helps reduce the risk of kidney stones, a potential side effect of allopurinol use. Adequate hydration is essential to prevent kidney stone formation and maintain kidney function while taking this medication.
3. What is the correct definition of drug absorption?
- A. Movement of a drug from the site of administration to various tissues of the body
- B. Describes the absorption, distribution, metabolism, and excretion of drugs
- C. These types of drugs can be taken over the counter
- D. This addresses how various drugs affect different forms of the body
Correct answer: A
Rationale: The correct definition of drug absorption is the movement of a drug from the site of administration into various tissues of the body. It is the process by which a drug is taken up and enters the systemic circulation. Choice B describes the pharmacokinetics of drugs, including absorption, distribution, metabolism, and excretion, but it is not a specific definition of drug absorption. Choice C is unrelated to drug absorption, as it refers to over-the-counter drugs. Choice D is too vague and does not specifically address the process of drug absorption.
4. A client has a new prescription for Spironolactone. Which of the following instructions should be provided?
- A. Take the medication with food.
- B. Avoid potassium-rich foods.
- C. Increase your intake of sodium.
- D. Monitor your blood pressure daily.
Correct answer: B
Rationale: The correct answer is to 'Avoid potassium-rich foods.' Spironolactone is a potassium-sparing diuretic, and consuming foods high in potassium can lead to hyperkalemia, a potential side effect of the medication. Therefore, the client should be advised to avoid potassium-rich foods to prevent complications. Choices A, C, and D are incorrect. Taking Spironolactone with food is not necessary for its effectiveness. Increasing sodium intake is not typically recommended with Spironolactone therapy. While monitoring blood pressure is important, it is not specifically related to the use of Spironolactone.
5. A client has a new prescription for Sucralfate. Which of the following instructions should the nurse include?
- A. Take the medication on an empty stomach.
- B. Increase your intake of high-sodium foods.
- C. Take the medication with a full glass of milk.
- D. Expect your stools to be black and tarry.
Correct answer: A
Rationale: The correct instruction that the nurse should include for a client prescribed Sucralfate is to take the medication on an empty stomach. Sucralfate works by forming a protective barrier over ulcers, which is most effective when the stomach is empty. Taking it with food or other medications may decrease its effectiveness. Instructing the client to take Sucralfate on an empty stomach helps ensure optimal therapeutic benefits. Choices B, C, and D are incorrect because increasing high-sodium foods is not related to Sucralfate therapy, taking the medication with a full glass of milk is not recommended as it may decrease its effectiveness, and the presence of black and tarry stools is not an expected outcome of Sucralfate.
