ATI Proctored Pharmacology Test
1. Which of the following drugs has a therapeutic effect that increases cardiac output and slows heart rate?
- A. Heparin
- B. Alprazolam
- C. Digoxin
- D. Levothyroxine
Correct answer: C
Rationale: Digoxin is the correct answer. It is a medication known for its positive inotropic effects, which increase cardiac output, and negative chronotropic effects, which slow the heart rate. These effects are achieved by inhibiting the sodium-potassium ATPase pump in myocardial cells. Therefore, Digoxin is commonly prescribed to manage conditions like heart failure and atrial fibrillation, where enhancing cardiac output and reducing heart rate are beneficial. Choices A, B, and D are incorrect because Heparin is an anticoagulant, Alprazolam is a benzodiazepine used for anxiety disorders, and Levothyroxine is a thyroid hormone replacement drug, none of which have the specified therapeutic effects on cardiac function.
2. A healthcare professional is caring for a client who is receiving treatment with carboplatin. Which of the following findings should the healthcare professional monitor?
- A. Hyperglycemia
- B. Ototoxicity
- C. Hypertension
- D. Bradycardia
Correct answer: B
Rationale: The healthcare professional should monitor the client for ototoxicity when receiving carboplatin. Ototoxicity is a known serious adverse effect associated with this medication, characterized by damage to the inner ear structures leading to hearing loss or balance issues. Monitoring for hearing changes and balance problems is crucial to detect ototoxicity early and prevent further complications. Hyperglycemia, hypertension, and bradycardia are not typically associated with carboplatin therapy.
3. A nurse is caring for a client in an outpatient facility who has been taking Acarbose for type 2 Diabetes Mellitus. Which of the following laboratory tests should the nurse plan to monitor?
- A. WBC
- B. Serum potassium
- C. Platelet count
- D. Liver function test
Correct answer: D
Rationale: The correct answer is D, Liver function test. Acarbose can cause liver toxicity when taken long-term. Monitoring liver function tests periodically is essential to assess for any potential liver damage. Choices A, B, and C are incorrect because Acarbose does not directly impact white blood cell count, serum potassium levels, or platelet count.
4. A client with cirrhosis is about to receive a dose of lactulose. The client questions the need for the medication, stating they are not constipated. The nurse should explain that lactulose is used in cirrhosis to reduce levels of which component in the bloodstream?
- A. Glucose
- B. Ammonia
- C. Potassium
- D. Bicarbonate
Correct answer: B
Rationale: Lactulose is administered to clients with cirrhosis to lower blood ammonia levels, thus aiding in the prevention of hepatic encephalopathy. Elevated ammonia levels in cirrhosis can lead to cognitive impairment and hepatic encephalopathy. Therefore, the correct answer is B (Ammonia). Glucose (Choice A) is not the component targeted by lactulose in cirrhosis. Potassium (Choice C) and Bicarbonate (Choice D) are not directly affected by lactulose administration in cirrhosis.
5. While reviewing a client's medical history, a healthcare professional notes a prescription for Digoxin. Which of the following findings is a manifestation of Digoxin toxicity?
- A. Elevated blood pressure
- B. Bradycardia
- C. Yellow-tinged vision
- D. Ringing in the ears
Correct answer: C
Rationale: Yellow-tinged vision is a visual disturbance associated with Digoxin toxicity, often accompanied by other symptoms like nausea, vomiting, and confusion. Bradycardia is a common therapeutic effect of Digoxin, while elevated blood pressure and ringing in the ears are not typically associated with Digoxin toxicity. Therefore, the correct answer is yellow-tinged vision as a manifestation of Digoxin toxicity.
