1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

2. The nurse is preparing to administer the 0800 dose of 20 units of Humulin R to an 8-year-old girl diagnosed with Type 1 diabetes. The mother comments that her daughter is a very picky eater and many times does not eat meals. Which intervention should the nurse implement first?

Correct answer: B

Rationale: The correct answer is to ask the girl if she will be eating her breakfast this morning. This is important to determine if the child will be consuming food, which is crucial information before administering insulin. If the child does not plan to eat, administering the full dose of insulin may lead to hypoglycemia. Choice A is incorrect as administering the insulin without knowing if the child will eat can be dangerous. Choice C is not the first intervention because the immediate concern is the child's meal intake. Choice D, while important, is not the first step in this situation.

3. A male client is admitted to the mental health unit because he experiences panic attacks when driving on the freeway. To attempt to desensitize this fear, what action should the nurse encourage the client to implement?

Correct answer: B

Rationale: Visualization techniques, such as visualizing himself driving each route to the freeway, are commonly used in desensitization therapy to help clients gradually overcome their fears. Watching videos of others driving or taking medication do not actively involve the client in facing their fear, which is essential in desensitization therapy. Getting in the car with a support person during rush hour may exacerbate the client's anxiety rather than help in desensitization.

4. When caring for a laboring client whose contractions are occurring every 2 to 3 min, the nurse should document that the pump is infusing how many ml/hr?

Correct answer: A

Rationale: To calculate the infusion rate, we first need to determine the frequency of contractions per hour. If contractions are occurring every 2 to 3 minutes, this corresponds to 20 to 30 contractions in an hour (60 minutes). The average is 25 contractions in an hour. The pump should be infusing 1 ml for each contraction, so the infusion rate should be 25 ml/hr. Therefore, the correct answer is 42 ml/hr. Choices B, C, and D are incorrect as they do not align with the calculation based on the given data.

5. A client who is 32-weeks pregnant is diagnosed with partial placenta previa. Which instruction should the nurse include in this client’s teaching plan?

Correct answer: C

Rationale: Refraining from sexual intercourse helps prevent complications with partial placenta previa.
