1. 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.
2. When teaching a client with a new prescription for furosemide, which instruction should the nurse include?
- A. Take this medication in the morning.
- B. Avoid foods high in potassium.
- C. Take this medication on an empty stomach.
- D. Limit fluid intake to 1 liter per day.
Correct answer: A
Rationale: The correct instruction for furosemide, a diuretic, is to take it in the morning to prevent nocturia. Taking it in the morning helps to prevent frequent urination during the night, allowing the client to have uninterrupted sleep. This timing also coincides with the body's natural diuretic response, which is typically more active during the day. Choices B, C, and D are incorrect because furosemide does not require avoiding foods high in potassium, taking it on an empty stomach, or limiting fluid intake to 1 liter per day.
3. A healthcare provider is planning care for a client with brain cancer experiencing headaches. Which of the following adjuvant medications is indicated for this client?
- A. Dexamethasone
- B. Methylphenidate
- C. Hydroxyzine
- D. Amitriptyline
Correct answer: A
Rationale: Dexamethasone, a glucocorticoid, is indicated for clients with brain cancer experiencing headaches as it decreases inflammation and swelling. It is commonly used to reduce cerebral edema and relieve pressure caused by the tumor. Methylphenidate (Choice B) is a central nervous system stimulant used in conditions like ADHD and narcolepsy, not for brain cancer headaches. Hydroxyzine (Choice C) is an antihistamine used for anxiety and allergic conditions, not indicated for brain cancer headaches. Amitriptyline (Choice D) is a tricyclic antidepressant used for depression, neuropathic pain, and migraine prophylaxis, but not typically indicated for brain cancer headaches.
4. Hydrochlorothiazide is classified as a
- A. Anti-inflammatory
- B. Antiarrhythmic
- C. Diuretic
- D. Antifungal
Correct answer: C
Rationale: Hydrochlorothiazide is classified as a diuretic. Diuretics are medications that help the body get rid of excess salt and water by increasing urine production, reducing fluid retention, and lowering blood pressure. Option A, Anti-inflammatory, is incorrect because hydrochlorothiazide does not primarily reduce inflammation. Option B, Antiarrhythmic, is incorrect because hydrochlorothiazide is not used to correct heart rhythm irregularities. Option D, Antifungal, is incorrect because hydrochlorothiazide is not used to treat fungal infections.
5. Which of the following drugs has a therapeutic effect that prevents thromboembolic events?
- A. Warfarin
- B. Amlodipine
- C. Nitroglycerin
- D. Clopidogrel
Correct answer: A
Rationale: The correct answer is Warfarin. Warfarin is an anticoagulant medication that helps prevent thromboembolic events by inhibiting the formation of blood clots. It is commonly used to reduce the risk of strokes or heart attacks in patients at risk for thrombosis.
