ATI Pharmacology Proctored Exam
1. A client is withdrawing from alcohol and has a new prescription for Propranolol. Which of the following information should be included in the teaching?
- A. Increases the risk for seizure activity.
- B. Provides a form of aversion therapy.
- C. Decreases cravings.
- D. Results in mild hypertension.
Correct answer: C
Rationale: The correct answer is C: 'Decreases cravings.' Propranolol is commonly used as an adjunct medication during alcohol withdrawal to help reduce cravings for alcohol. It does not increase the risk for seizure activity, provide aversion therapy, or result in mild hypertension. By decreasing cravings, Propranolol can support the client in managing alcohol withdrawal symptoms and promoting abstinence. Therefore, it is important to educate the client on how Propranolol can help them cope with alcohol cravings effectively.
2. Which of the following drugs is associated with Stevens-Johnson syndrome?
- A. Valproic acid
- B. Quinidine
- C. Isoniazid
- D. Ethosuximide
Correct answer: D
Rationale: Stevens-Johnson syndrome is a severe skin reaction that can be associated with Ethosuximide.
3. A client has a new prescription for Warfarin. Which of the following statements by the client indicates a need for further teaching?
- A. I will avoid eating large amounts of green leafy vegetables.
- B. I will take my medication at the same time every day.
- C. I will increase my intake of foods high in potassium.
- D. I will report any signs of bleeding to my provider.
Correct answer: C
Rationale: The correct answer is C because Warfarin interacts with vitamin K, not potassium. Therefore, the client needs to be cautious with foods high in vitamin K, such as green leafy vegetables, rather than foods high in potassium. Choices A, B, and D are correct statements regarding Warfarin therapy and do not indicate a need for further teaching.
4. A healthcare provider is reviewing the medical history of a client who is scheduled for surgery and takes Warfarin daily. Which of the following laboratory results should the healthcare provider monitor?
- A. Potassium level
- B. INR
- C. BUN
- D. Platelet count
Correct answer: B
Rationale: The INR (International Normalized Ratio) is the most important lab value to monitor in a client taking warfarin. Warfarin is an anticoagulant, and the INR reflects the effectiveness of anticoagulation therapy. Monitoring the INR helps ensure the client is within the therapeutic range to prevent both clotting and bleeding complications.
5. Which drug undergoes extensive first-pass hepatic metabolism?
- A. Heparin
- B. Insulin
- C. Propranolol
- D. Nitroglycerin
Correct answer: C
Rationale: Propranolol undergoes extensive first-pass hepatic metabolism in the liver. When administered orally, propranolol is extensively metabolized by the liver before reaching systemic circulation, leading to reduced bioavailability. This process is known as first-pass hepatic metabolism, which significantly affects the drug's effectiveness and necessitates higher oral doses compared to other routes of administration. Heparin (Choice A) is not metabolized by the liver but excreted unchanged by the kidneys. Insulin (Choice B) is a peptide hormone that is not subject to significant first-pass metabolism. Nitroglycerin (Choice D) is primarily metabolized in the blood and tissues, bypassing significant first-pass metabolism in the liver.
