1. A healthcare provider is providing discharge instructions to a client who has a new prescription for Warfarin. Which of the following foods should the provider instruct the client to avoid?

A. Broccoli
B. Bananas
C. Chicken
D. Potatoes

Correct answer: A

Rationale: Clients taking Warfarin should avoid foods high in vitamin K, such as broccoli, as they can interfere with the effectiveness of the medication. Vitamin K can counteract the anticoagulant effects of Warfarin, potentially leading to blood clotting issues. Broccoli is rich in vitamin K, so its consumption should be consistent to avoid fluctuations in the medication's effectiveness. Bananas, chicken, and potatoes are not known to significantly interact with Warfarin and do not pose a risk of affecting its anticoagulant properties.

2. What is the antidote for Heparin?

A. Protamine sulfate
B. Vitamin K
C. Naloxone
D. Toradol

Correct answer: A

Rationale: The correct answer is A: Protamine sulfate. Heparin is an anticoagulant that prevents blood clotting. Protamine sulfate is the antidote for Heparin as it binds to heparin, neutralizing its anticoagulant effects. Vitamin K is not the antidote for Heparin; it is used to reverse the effects of warfarin, another anticoagulant. Naloxone is an opioid antagonist for opioids, and Toradol is a nonsteroidal anti-inflammatory drug (NSAID) for pain relief. Therefore, the correct antidote for Heparin is Protamine sulfate.

3. Which of the following is not a side effect of the cholinoreceptor blocker (Atropine)?

A. Increased pulse
B. Diarrhea
C. Constipation
D. Mydriasis

Correct answer: B

Rationale: Atropine, an anticholinergic drug, commonly causes side effects like increased pulse, mydriasis (dilated pupils), and constipation due to its inhibitory effect on the parasympathetic nervous system. Diarrhea is not typically a side effect of Atropine, making it the correct answer.

4. A client with type 2 Diabetes Mellitus is starting Repaglinide. Which statement by the client indicates understanding of the administration of this medication?

A. I'll take this medicine with my meals.
B. I'll take this medicine 30 minutes before I eat.
C. I'll take this medicine just before I go to bed.
D. I'll take this medicine as soon as I wake up in the morning.

Correct answer: B

Rationale: The correct answer is B. Repaglinide causes a rapid, short-lived release of insulin. To ensure the insulin is available when food is digested, the client should take this medication 30 minutes before each meal. This timing aligns the medication with the expected postprandial rise in blood glucose levels, optimizing its effectiveness in controlling blood sugar levels. Choices A, C, and D are incorrect because taking Repaglinide with meals, just before bed, or as soon as waking up does not align with the medication's mechanism of action and timing needed for optimal effectiveness.

5. Which of the following conditions is not treated with Methotrexate?

A. Sarcomas
B. Leukemias
C. Ectopic pregnancy
D. Rheumatic fever

Correct answer: D

Rationale: The correct answer is D. Methotrexate is not typically used to treat rheumatic fever, which is more commonly managed with antibiotics to eradicate the underlying infection. Methotrexate is commonly used in the treatment of conditions like sarcomas, leukemias, and ectopic pregnancies due to its anti-inflammatory and anti-cancer properties.
