ATI Pharmacology Proctored Exam 2023
1. A client is taking Sucralfate PO for Peptic Ulcer Disease and has a new prescription for phenytoin to control seizures. Which of the following instructions should the nurse include?
- A. Take an antacid with the sucralfate.
- B. Take sucralfate with a glass of milk.
- C. Allow a 2-hour interval between these medications.
- D. Chew the sucralfate thoroughly before swallowing.
Correct answer: C
Rationale: Sucralfate can interfere with the absorption of phenytoin. To prevent this interaction, the client should allow a 2-hour interval between taking sucralfate and phenytoin. This timing helps to ensure adequate absorption and effectiveness of both medications without compromising therapeutic outcomes. Choices A, B, and D are incorrect because taking an antacid with sucralfate, taking sucralfate with a glass of milk, and chewing sucralfate thoroughly before swallowing do not address the need for a 2-hour interval between these medications to prevent interference with phenytoin absorption.
2. What does it mean when a medication has a half-life?
- A. It only lasts for 30 minutes after the medication is given
- B. How long it takes for half of the dose to be eliminated from the bloodstream
- C. It is the peak of how effective the medicine is
- D. Drug is greatly reduced before it reaches the systemic circulation
Correct answer: B
Rationale: When a medication has a half-life, it refers to the time it takes for half of the dose to be eliminated from the bloodstream. This parameter is crucial in understanding the duration of action and dosing intervals for medications in clinical practice. Choice A is incorrect as the half-life is not about how long the medication lasts but about elimination from the body. Choice C is incorrect because the half-life is not about the peak effectiveness of the medicine. Choice D is incorrect as it does not accurately define the concept of half-life.
3. A patient states he experiences anxiety and has panic attacks at least once a week. What might be helpful for this patient?
- A. Phenytoin (Dilantin)
- B. Lithium
- C. Alprazolam (Xanax)
- D. Spironolactone
Correct answer: C
Rationale: Alprazolam (Xanax) is a medication commonly prescribed to treat anxiety disorders and panic attacks. It belongs to the class of medications known as benzodiazepines, which work by enhancing the effects of gamma-aminobutyric acid (GABA) in the brain to produce a calming effect. Phenytoin is an antiepileptic drug, not typically used for anxiety or panic attacks. Lithium is primarily used to treat bipolar disorder, not anxiety. Spironolactone is a diuretic primarily used to treat conditions like high blood pressure and heart failure, not anxiety or panic attacks.
4. A nurse is teaching a client who has a new prescription for Spironolactone. Which of the following adverse effects should the nurse instruct the client to monitor?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Hypocalcemia
- D. Hyponatremia
Correct answer: A
Rationale: Spironolactone is a potassium-sparing diuretic, so the nurse should monitor the client for hyperkalemia, which can cause muscle weakness and cardiac dysrhythmias.
5. A client has a new prescription for Valsartan, and a nurse is providing discharge teaching. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Avoid potassium-rich foods.
- C. Expect to feel drowsy.
- D. Monitor your blood pressure daily.
Correct answer: D
Rationale: Monitoring blood pressure daily is crucial for clients taking Valsartan, an angiotensin II receptor blocker, to ensure effective management of hypertension. Valsartan helps lower blood pressure by relaxing blood vessels, and regular monitoring helps track the medication's effectiveness and any potential side effects. Choices A, B, and C are incorrect because Valsartan does not need to be taken with food, avoiding potassium-rich foods is not specifically required for this medication, and feeling drowsy is not a common side effect of Valsartan.
