ATI Pharmacology Proctored Exam 2024
1. A staff educator is reviewing medication dosages and factors that influence medication metabolism with a group of nurses at an in-service presentation. Which of the following factors should the educator include as a reason to administer lower medication dosages? (Select all that apply.)
- A. Increased renal secretion
- B. Increased medication-metabolizing enzymes
- C. Liver failure
- D. Peripheral vascular disease
Correct answer: C
Rationale: Liver failure impairs metabolism, leading to increased medication concentrations. When liver function is compromised, lower dosages are necessary to prevent adverse effects. Increased renal secretion is not a reason for lower medication dosages, as it primarily affects excretion rather than metabolism. Increased medication-metabolizing enzymes would usually require higher dosages to achieve the desired effect. Peripheral vascular disease does not directly impact medication metabolism or dosage requirements.
2. A client is prescribed Lithium. Which of the following laboratory values should be monitored to assess for potential toxicity?
- A. Serum sodium
- B. Serum lithium
- C. Serum potassium
- D. Serum calcium
Correct answer: B
Rationale: When a client is prescribed Lithium, monitoring serum lithium levels is crucial to ensure they remain within the therapeutic range and to assess for potential toxicity. Monitoring serum lithium levels helps prevent adverse effects associated with lithium toxicity, such as nausea, vomiting, diarrhea, tremors, and confusion.
3. What is the primary use of lithium?
- A. Lower blood glucose
- B. Slow the heart rate
- C. Stabilize mood
- D. Heal ulcers
Correct answer: C
Rationale: The correct answer is C: Stabilize mood. Lithium is primarily used to stabilize mood, especially in conditions like bipolar disorder. It helps in reducing the frequency and severity of manic episodes, making it an essential medication for mood stabilization. Choices A, B, and D are incorrect as lithium is not used to lower blood glucose, slow the heart rate, or heal ulcers.
4. A client in a critical care unit is postoperative following a right pneumonectomy. After extubation from the ventilator, in which of the following positions should the client be placed?
- A. Prone
- B. On the nonoperative side
- C. Sims'
- D. Semi-Fowler's
Correct answer: D
Rationale: After a pneumonectomy, positioning the client in a semi-Fowler's position is crucial for optimal ventilation. This position helps improve lung expansion on the remaining side, facilitating better oxygenation and preventing complications like atelectasis. Placing the client prone, on the nonoperative side, or in Sims' position would not provide the same respiratory benefits post-pneumonectomy.
5. A client has a new prescription for Iron supplements. Which of the following instructions should be included?
- A. Take the medication with a glass of milk.
- B. Avoid taking the medication with orange juice.
- C. Increase fiber intake to prevent constipation.
- D. Expect stools to be bright red.
Correct answer: C
Rationale: The correct answer is C: 'Increase fiber intake to prevent constipation.' Iron supplements commonly cause constipation as a side effect. Increasing fiber intake can help alleviate this issue by promoting regular bowel movements and preventing constipation. Choice A is incorrect as iron absorption is hindered when taken with milk. Choice B is not directly related to iron supplements. Choice D is incorrect as iron supplements do not typically cause bright red stools.
