ATI Pharmacology Proctored Exam
1. A healthcare professional is preparing to initiate IV therapy for an older adult client. Which of the following actions should the professional plan to take?
- A. Use a blood pressure cuff to distend the veins.
- B. Select the antecubital area to insert the IV catheter.
- C. Distend the veins by using a blood pressure cuff.
- D. Direct the client to lower his arm below his heart.
Correct answer: C
Rationale: The correct answer is C. The healthcare professional should distend the veins using a blood pressure cuff to make the veins more visible and accessible for IV catheter insertion. This technique helps reduce the risk of overfilling the vein, which can lead to complications such as hematoma formation. Choices A, B, and D are incorrect because while selecting the antecubital area is often appropriate for IV insertion in adults, the key action in this scenario is to distend the veins using a blood pressure cuff to facilitate the procedure.
2. When educating a client with a new prescription for Atorvastatin to treat Hyperlipidemia, which instruction should the nurse include?
- A. Take this medication in the morning.
- B. Avoid drinking grapefruit juice.
- C. Increase your intake of green, leafy vegetables.
- D. Expect your stools to turn clay-colored.
Correct answer: B
Rationale: The correct instruction for the nurse to include when educating a client with a new prescription for Atorvastatin to treat Hyperlipidemia is to avoid drinking grapefruit juice. Grapefruit juice can increase the blood levels of atorvastatin, leading to an elevated risk of serious side effects such as liver damage and muscle problems. It is essential for the client to be aware of this potential interaction and to follow the nurse's advice to avoid grapefruit juice while taking Atorvastatin. Choices A, C, and D are incorrect. Taking Atorvastatin in the morning is a common recommendation but not the priority over avoiding grapefruit juice. Increasing intake of green, leafy vegetables is generally a healthy dietary choice but is not specific to the medication. Expecting stools to turn clay-colored is not a common side effect of Atorvastatin.
3. The healthcare professional is preparing to administer atenolol (Tenormin) to a client with angina. Which vital sign would cause the healthcare professional to question administering this drug?
- A. Respirations 12 breaths per minute
- B. Pulse 52 beats per minute
- C. Blood pressure 134/72
- D. Oxygen saturation 95%
Correct answer: B
Rationale: Atenolol is a beta-blocker medication that can lower heart rate. A pulse of 52 beats per minute is relatively low and administering atenolol could further decrease the heart rate, potentially leading to bradycardia. Monitoring the pulse rate and holding the medication if the pulse is below the prescribed parameters is crucial to prevent adverse effects such as bradycardia and hypotension.
4. To which pharmacologic classification does the drug propranolol belong?
- A. Beta Blockers
- B. Cholinergics
- C. Immune globulins
- D. Barbiturates
Correct answer: A
Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.
5. When teaching a client with a new prescription for Warfarin, which herbal supplement should the nurse instruct the client to avoid?
- A. St. John's wort
- B. Echinacea
- C. Garlic
- D. Ginseng
Correct answer: A
Rationale: The correct answer is St. John's wort. St. John's wort can reduce the effectiveness of Warfarin by interacting with its metabolism, potentially leading to decreased anticoagulant effects. Therefore, the nurse should instruct the client to avoid using St. John's wort while taking Warfarin to prevent adverse drug interactions. Echinacea, garlic, and ginseng are not the correct answers in this case. While these herbal supplements may also interact with Warfarin and affect its efficacy, St. John's wort has a well-known interaction with Warfarin that can significantly impact its anticoagulant effects. Educating the client about the specific interaction between St. John's wort and Warfarin is crucial to ensure patient safety and the medication's therapeutic benefit.
