ATI Pharmacology Proctored Exam
1. A client has a new prescription for Digoxin to treat heart failure. Which of the following instructions should the nurse include in the teaching?
- A. Contact provider if heart rate is less than 60/min.
- B. Check pulse rate for 30 seconds and multiply the result by 2.
- C. Increase intake of sodium.
- D. Take with food if nausea occurs.
Correct answer: A
Rationale: The correct instruction for a client prescribed Digoxin for heart failure is to contact the provider if the heart rate is less than 60/min. Digoxin can affect heart rate, and a heart rate below 60/min may indicate toxicity, requiring prompt medical attention. Checking the pulse rate accurately and seeking medical advice are essential components of safe medication management. Choices B, C, and D are incorrect. Choice B is related to checking the pulse rate but does not address the critical action of contacting the provider if it is below 60/min. Increasing intake of sodium (Choice C) is inappropriate as high sodium levels can worsen heart failure. Taking Digoxin with food if nausea occurs (Choice D) does not address a critical aspect of Digoxin administration related to heart rate monitoring.
2. When teaching a client with a new prescription for Amiodarone, which instruction should the nurse include?
- A. Take this medication with meals.
- B. Avoid drinking grapefruit juice.
- C. Take this medication at bedtime.
- D. Increase your intake of sodium-rich foods.
Correct answer: B
Rationale: The correct instruction is to avoid drinking grapefruit juice when taking Amiodarone. Grapefruit juice can inhibit the metabolism of Amiodarone, leading to increased blood levels of the drug and potentially causing adverse effects like cardiac toxicity. Choices A, C, and D are incorrect because taking Amiodarone with meals, at bedtime, or increasing sodium-rich foods intake are not relevant instructions for this medication.
3. A client has a new prescription for Furosemide. Which of the following adverse effects should the nurse monitor?
- A. Hyperkalemia
- B. Hyponatremia
- C. Hypernatremia
- D. Hypercalcemia
Correct answer: B
Rationale: The correct answer is B: Hyponatremia. Furosemide, a diuretic, commonly causes hyponatremia (low sodium levels) as it increases the excretion of sodium. The nurse needs to monitor the client for signs of hyponatremia, such as confusion, weakness, and muscle cramps, by checking electrolyte levels regularly. Choices A, C, and D are incorrect because hyperkalemia (choice A), hypernatremia (choice C), and hypercalcemia (choice D) are not typically associated with Furosemide use.
4. A client in a long-term care facility has Hypothyroidism and a new prescription for Levothyroxine. Which of the following dosage schedules should the nurse expect for this client?
- A. The client will start at a high dose, and the dose will be tapered as needed.
- B. The client will remain on the initial dosage during the course of treatment.
- C. The client's dosage will be adjusted daily based on blood levels.
- D. The client will start on a low dose, which will be gradually increased.
Correct answer: D
Rationale: The nurse should expect that levothyroxine will be started at a low dose and gradually increased over several weeks. This cautious approach is crucial, especially in older adult clients, to prevent toxicity and ensure optimal therapeutic outcomes for managing hypothyroidism. Choice A is incorrect because starting at a high dose and tapering as needed is not the standard approach for levothyroxine. Choice B is incorrect because the initial dosage is typically adjusted to reach the optimal therapeutic dose. Choice C is incorrect as adjusting the dosage daily based on blood levels is not necessary for levothyroxine, as it has a long half-life and requires time to reach a steady state.
5. A healthcare professional in a provider's office is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?
- A. Calcium 9.2 mg/dL
- B. Calcium 10.3 mg/dL
- C. Potassium 3.4 mEq/L
- D. Potassium 4.8 mEq/L
Correct answer: C
Rationale: The correct answer is C: Potassium 3.4 mEq/L. Potassium 3.4 mEq/L is below the expected reference range and puts a client at risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, especially in older clients taking Digoxin, as potassium plays a crucial role in the heart's electrical activity. Choices A and B are related to calcium levels, which do not directly increase the risk of Digoxin toxicity. Choice D, Potassium 4.8 mEq/L, is within the expected reference range and would not increase the risk of Digoxin toxicity.
