ATI Pharmacology Proctored Exam 2019
1. A healthcare professional in an emergency unit is reviewing the medical record of a client who is being evaluated for angle-closure glaucoma. Which of the following findings is indicative of this condition?
- A. Insidious onset of painless loss of vision
- B. Gradual reduction in peripheral vision
- C. Severe pain around the eyes
- D. Intraocular pressure 12 mm Hg
Correct answer: C
Rationale: Severe pain around the eyes that radiates over the face is a classic symptom of acute angle-closure glaucoma. This intense pain is often associated with other symptoms such as blurred vision, halos around lights, redness in the eye, and sometimes nausea and vomiting. Immediate medical attention is required to prevent permanent vision loss. Choices A, B, and D are incorrect. Insidious onset of painless loss of vision is more indicative of conditions like macular degeneration. Gradual reduction in peripheral vision is commonly seen in conditions like open-angle glaucoma. An intraocular pressure of 12 mm Hg is within the normal range and is not typical of angle-closure glaucoma.
2. When teaching a client with a new prescription for Simvastatin, which instruction should be included?
- A. Take this medication with food.
- B. Avoid drinking grapefruit juice.
- C. Take this medication in the morning.
- D. Increase your intake of potassium-rich foods.
Correct answer: B
Rationale: The correct instruction for a client with a new prescription for Simvastatin is to avoid drinking grapefruit juice. Grapefruit juice can inhibit the metabolism of Simvastatin, leading to increased blood levels of the drug and a higher risk of adverse effects such as muscle pain and liver damage. It is important to educate the client about this potential interaction to ensure the safe and effective use of the medication. Choices A, C, and D are incorrect because taking Simvastatin with food or in the morning and increasing potassium-rich foods intake are not specifically related to the safe use of Simvastatin. Avoiding grapefruit juice is crucial to prevent drug interactions.
3. A client has been on levothyroxine therapy for several months. Which of the following findings indicates a therapeutic response to the medication?
- A. Decrease in level of thyroxine (T4)
- B. Increase in weight
- C. Increase in hours of sleep per night
- D. Decrease in level of thyroid stimulating hormone (TSH)
Correct answer: D
Rationale: A therapeutic response to levothyroxine is indicated by a decrease in the level of TSH. This decrease signifies that the body requires less stimulation to produce thyroid hormone, reflecting a normalization of thyroid function due to the medication's effectiveness. Choices A, B, and C are incorrect as an increase in T4 levels, weight gain, and increased sleep hours are not indicative of a therapeutic response to levothyroxine therapy.
4. A client is taking Furosemide for heart failure. Which of the following findings is a priority to report to the provider?
- A. Weight loss of 1 kg in 24 hours
- B. Blood pressure of 104/60 mm Hg
- C. Potassium level of 3.5 mEq/L
- D. Urine output of 200 mL in 8 hours
Correct answer: D
Rationale: A urine output of 200 mL in 8 hours indicates decreased kidney function and potential worsening heart failure. This finding should be reported promptly to the provider for further evaluation and management to prevent complications. Weight loss, while significant, may be expected with diuretic use. A blood pressure of 104/60 mm Hg is within normal range and can be managed. A potassium level of 3.5 mEq/L is slightly low but not an immediate concern.
5. Why has an ACE inhibitor been prescribed following an MI?
- A. “This medication will lower your potassium level.â€
- B. “ACE inhibitors have been found to reduce mortality following MI.â€
- C. “ACE inhibitors are always prescribed with a beta blocker and calcium channel blocker following an MI.â€
- D. “This medication will treat your hypotension.â€
Correct answer: B
Rationale: Following a myocardial infarction (MI), ACE inhibitors are commonly prescribed due to their proven benefit in reducing mortality and improving outcomes post-MI. These medications help by decreasing the workload of the heart, preventing remodeling of the heart chambers, and improving survival rates. While ACE inhibitors may have effects on potassium levels, the primary reason for their prescription post-MI is their mortality-reducing properties.
