ATI Pharmacology Proctored Exam 2023 Quizlet
1. 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.
2. 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.
3. A client has a fungal infection and a new prescription for amphotericin B. Which of the following laboratory values should the nurse report to the provider before initiating the medication?
- A. Sodium 140 mEq/L
- B. Potassium 4.5 mEq/L
- C. BUN 55 mg/dL
- D. Glucose 120 mg/dL
Correct answer: C
Rationale: An elevated BUN level of 55 mg/dL should be reported before starting amphotericin B due to its nephrotoxic effects. Amphotericin B can cause kidney damage, and an elevated BUN indicates impaired kidney function, increasing the risk of further renal damage with this medication. Sodium, potassium, and glucose levels are not directly associated with the nephrotoxic effects of amphotericin B, making choices A, B, and D incorrect.
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. Which of the following is classified as a class IA Sodium Channel blocker?
- A. Quinidine
- B. Disopyramide
- C. Aminodarone
- D. Propafenone
Correct answer: A
Rationale: Quinidine is classified as a class IA sodium channel blocker. Class IA antiarrhythmics, like quinidine, work by blocking sodium channels and delaying repolarization. Propafenone, mentioned in the original rationale, is actually a class IC antiarrhythmic agent, not a class IA sodium channel blocker.
