1. Which drug is the antidote for Alprazolam?
- A. Physostigmine
- B. Protamine sulfate
- C. Flumazenil
- D. Acetylcysteine
Correct answer: C
Rationale: Flumazenil is the specific antidote used to reverse the effects of Alprazolam. Alprazolam is a benzodiazepine, and Flumazenil is a benzodiazepine receptor antagonist that works by competitively inhibiting the actions of benzodiazepines at the receptor site, effectively reversing their sedative and other effects. Physostigmine is not used as an antidote for benzodiazepine overdose and can have significant side effects. Protamine sulfate is used to reverse the effects of heparin, not benzodiazepines like Alprazolam. Acetylcysteine is used as an antidote for acetaminophen overdose, not benzodiazepines like Alprazolam.
2. What is the expected outcome of Valproate therapy?
- A. Decreased fever
- B. Decreased sense of anxiety
- C. Decreased blood pressure
- D. Decreased seizure activity
Correct answer: D
Rationale: The correct answer is D: Decreased seizure activity. Valproate is commonly used in the treatment of epilepsy to help control and reduce seizure frequency. Choices A, B, and C are incorrect because Valproate is not primarily used to treat fever, anxiety, or blood pressure issues.
3. A client has a new prescription for hydrochlorothiazide to treat hypertension. Which of the following instructions should be included?
- A. Take the medication in the morning.
- B. Increase intake of potassium-rich foods.
- C. Avoid sun exposure while taking this medication.
- D. Limit fluid intake to 1 liter per day.
Correct answer: B
Rationale: The correct instruction that should be included for a client prescribed hydrochlorothiazide is to increase the intake of potassium-rich foods. Hydrochlorothiazide, being a diuretic, can lead to hypokalemia by enhancing potassium excretion. Increasing consumption of potassium-rich foods like bananas or oranges can help prevent hypokalemia and maintain electrolyte balance. Choices A, C, and D are incorrect. Taking the medication in the morning is not a specific instruction related to hydrochlorothiazide. Avoiding sun exposure is more relevant for photosensitive medications, not hydrochlorothiazide. Limiting fluid intake to 1 liter per day is not necessary unless specifically advised by a healthcare provider.
4. During discharge instructions, a client with a new prescription for Phenytoin should be advised to take which of the following actions?
- A. Brush and floss your teeth regularly.
- B. Avoid drinking grapefruit juice.
- C. Take this medication on an empty stomach.
- D. Increase your intake of calcium-rich foods.
Correct answer: A
Rationale: The correct instruction for a client with a new prescription for Phenytoin is to brush and floss their teeth regularly. Phenytoin is known to cause gingival hyperplasia, a condition that affects the gums. By maintaining good oral hygiene practices such as regular brushing and flossing, the client can help minimize the risk of developing this side effect. Choices B, C, and D are incorrect. Avoiding grapefruit juice is more relevant for medications affected by grapefruit juice metabolism, taking medication on an empty stomach is not specifically indicated for Phenytoin, and increasing calcium-rich foods is not directly related to the side effects or administration of Phenytoin.
5. A hospitalized client receiving IV heparin for a deep-vein thrombosis begins vomiting blood. After the heparin has been stopped, which of the following medications should the nurse prepare to administer?
- A. Vitamin K1
- B. Atropine
- C. Protamine
- D. Calcium gluconate
Correct answer: C
Rationale: In this scenario, the client is experiencing a serious complication of heparin therapy, likely due to heparin-induced thrombocytopenia. Protamine is the antidote for heparin and can reverse its anticoagulant effects. It is essential to administer protamine promptly to counteract the effects of heparin and manage the bleeding. Vitamin K1 is used to reverse the effects of warfarin, not heparin. Atropine is used to treat bradycardia or some types of poisoning. Calcium gluconate is used to manage hyperkalemia or calcium channel blocker toxicity, not to reverse heparin's effects.
