ATI Pharmacology Proctored Exam 2023 Quizlet
1. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:
- A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
- B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
- C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
- D. To lower blood glucose by stimulating the release of insulin
Correct answer: A
Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.
2. Which of the following conditions are not treated with Barbiturates?
- A. Seizures
- B. Hypotension
- C. Insomnia
- D. Anxiety
Correct answer: B
Rationale: Hypotension is not treated with barbiturates. Barbiturates are primarily used for treating seizures, insomnia, and anxiety, but they are not indicated for the treatment of hypotension.
3. A client is being educated by a healthcare provider about Terbutaline. Which of the following statements by the client indicates understanding of the teaching?
- A. This medication will stop my contractions.
- B. This medication will prevent vaginal bleeding.
- C. This medication will promote blood flow to my baby.
- D. This medication will increase my prostaglandin production.
Correct answer: A
Rationale: The correct answer is A. Terbutaline works by blocking beta2-adrenergic receptors, leading to uterine smooth muscle relaxation and stopping contractions. It is commonly used to delay preterm labor. Choice B is incorrect because Terbutaline is not used to prevent vaginal bleeding. Choice C is incorrect because Terbutaline's primary action is not related to promoting blood flow to the baby. Choice D is incorrect because Terbutaline does not increase prostaglandin production; instead, it works by blocking beta2-adrenergic receptors.
4. A client has a new prescription for Efavirenz, an NNRTI. Which of the following instructions should the nurse include?
- A. Take this medication at bedtime to prevent drowsiness.
- B. Take this medication with a glass of milk.
- C. Take this medication with a glass of juice.
- D. Take this medication at the same time every day.
Correct answer: A
Rationale: The correct instruction is to take Efavirenz at bedtime to prevent drowsiness and manage central nervous system side effects like dizziness and vivid dreams. While it is important to take the medication at the same time daily for consistent blood levels, the emphasis should be on bedtime to minimize the impact of these side effects. Choices B and C suggesting taking the medication with milk or juice are incorrect and not relevant to optimizing Efavirenz therapy.
5. A nurse is teaching a client who has a new prescription for Atenolol. Which of the following adverse effects should the nurse instruct the client to monitor?
- A. Tachycardia
- B. Hypoglycemia
- C. Bradycardia
- D. Hypertension
Correct answer: C
Rationale: Atenolol is a beta-blocker that can cause bradycardia as an adverse effect. The client should monitor their pulse regularly and report any significant decreases.
