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 client prescribed Warfarin is receiving discharge instructions from a nurse. Which of the following herbal supplements should the nurse instruct the client to avoid?
- A. St. John's wort
- B. Echinacea
- C. Garlic
- D. Ginseng
Correct answer: A
Rationale: St. John's wort can reduce the effectiveness of Warfarin by interacting with its metabolism pathways, potentially leading to decreased anticoagulant effects. Therefore, clients on Warfarin therapy should avoid St. John's wort. While echinacea, garlic, and ginseng are also herbal supplements that can interact with Warfarin, St. John's wort is particularly known for its significant impact on Warfarin metabolism. Echinacea may increase the risk of bleeding when taken with Warfarin, garlic may potentiate the anticoagulant effects of Warfarin, and ginseng may also increase the risk of bleeding. However, St. John's wort is the most crucial to avoid due to its significant impact on Warfarin metabolism.
3. When providing teaching to a client starting therapy with trastuzumab, which finding should the nurse instruct the client to report?
- A. Dyspnea
- B. Constipation
- C. Tinnitus
- D. Dry mouth
Correct answer: A
Rationale: The correct answer is A: Dyspnea. The nurse should instruct the client to report dyspnea because it can indicate pulmonary toxicity, a serious adverse effect of trastuzumab. Monitoring and early reporting of respiratory symptoms like dyspnea are essential to prevent further complications and ensure timely intervention. Choices B, C, and D are incorrect because constipation, tinnitus, and dry mouth are not typically associated with trastuzumab therapy and are not priority symptoms that require immediate reporting for this specific medication.
4. A child with Cystic Fibrosis has a new prescription for Acetylcysteine. Which of the following information should the nurse include in the instructions?
- A. Expect this medication to suppress your cough.
- B. Expect this medication to smell like rotten eggs.
- C. Expect this medication to cause euphoria.
- D. Expect this medication to turn your urine orange.
Correct answer: B
Rationale: The correct answer is B: 'Expect this medication to smell like rotten eggs.' Acetylcysteine contains sulfur, which gives it a characteristic rotten-egg odor. This smell is normal and expected when using this medication. Choices A, C, and D are incorrect. Acetylcysteine is not used to suppress cough, cause euphoria, or turn urine orange.
5. A client with HIV-1 infection is prescribed zidovudine as part of antiretroviral therapy. The nurse should monitor the client for which of the following adverse effects of this medication?
- A. Cardiac dysrhythmia
- B. Metabolic alkalosis
- C. Renal failure
- D. Aplastic anemia
Correct answer: D
Rationale: Corrected Rationale: Zidovudine is associated with the development of aplastic anemia, a serious adverse effect characterized by bone marrow suppression. Regular monitoring is essential to detect this side effect early and prevent complications. Cardiac dysrhythmia, metabolic alkalosis, and renal failure are not commonly associated with zidovudine use, making them incorrect choices for adverse effects of this medication.
