1. A client has a new prescription for Propranolol. Which of the following statements should the nurse include in teaching the client?
- A. You may experience a rapid heart rate while taking this medication.
- B. Take the medication with food.
- C. Avoid sudden changes in position.
- D. Increase your intake of high-sodium foods.
Correct answer: C
Rationale: The correct statement to include when teaching a client about Propranolol is to avoid sudden changes in position. Propranolol, a beta-blocker, can lead to dizziness and lightheadedness, particularly when changing positions. Therefore, clients should be advised to change positions slowly to prevent falls and related injuries. Choice A is incorrect because Propranolol actually helps lower heart rate and blood pressure. Choice B is not a specific requirement for taking Propranolol. Choice D is also incorrect as increasing high-sodium foods is not recommended with Propranolol which can affect blood pressure control.
2. A client has a new prescription for radioactive iodine to treat Hyperthyroidism. Which of the following instructions should the nurse include?
- A. Expect a metallic taste in the mouth.
- B. Avoid contact with pregnant women for 1 week.
- C. Administer iodine solution using a straw.
- D. Take thyroid replacement medication for 3 weeks after treatment.
Correct answer: B
Rationale: When a client undergoes radioactive iodine treatment for hyperthyroidism, they can emit radiation for a short time. To prevent radiation exposure to others, especially pregnant women, infants, and small children, clients should avoid close contact for about 1 week following therapy. This precaution is essential to protect vulnerable individuals from potential harm. Choice A is incorrect because a metallic taste in the mouth is not a common side effect of radioactive iodine treatment. Choice C is incorrect because administering iodine solution using a straw is not a standard practice in this treatment. Choice D is incorrect because taking thyroid replacement medication for 3 weeks after treatment is not a typical instruction associated with radioactive iodine therapy for hyperthyroidism.
3. A client is receiving Morphine IV for pain management. Which of the following actions should the nurse take to monitor for adverse effects?
- A. Monitor the client's respiratory rate every 15 minutes.
- B. Monitor the client's blood pressure every 30 minutes.
- C. Monitor the client's oxygen saturation every hour.
- D. Monitor the client's heart rate every 5 minutes.
Correct answer: A
Rationale: The correct action for the nurse to monitor for adverse effects of Morphine IV is to check the client's respiratory rate every 15 minutes. Respiratory depression is a potentially life-threatening adverse effect of Morphine. Monitoring the respiratory rate frequently allows for early detection and intervention if needed. Monitoring blood pressure, oxygen saturation, or heart rate alone may not provide early signs of respiratory depression, which is a critical adverse effect of Morphine IV.
4. Which of the following is a potassium-sparing diuretic?
- A. Furosemide
- B. Spironolactone
- C. Hydrochlorothiazide
- D. Bumetanide
Correct answer: B
Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion. This mechanism makes it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis. Choices A, C, and D are not potassium-sparing diuretics. Furosemide, hydrochlorothiazide, and bumetanide are loop diuretics and thiazide diuretics, respectively, which promote the excretion of potassium.
5. What is the primary action of warfarin as an anticoagulant?
- A. Prevents the formation of blood clots
- B. Dissolves existing blood clots
- C. Dilates coronary arteries
- D. Treats rhythm disturbances
Correct answer: A
Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.
