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. A client with diabetes mellitus reports feeling dizzy and has a blood glucose level of 50 mg/dl. What action should the nurse take first?

Correct answer: B

Rationale: Providing 15 grams of carbohydrate is the initial action to treat hypoglycemia. When a client with diabetes mellitus experiences symptoms of hypoglycemia, such as dizziness and with a blood glucose level of 50 mg/dl, the immediate priority is to raise their blood sugar levels quickly. Administering carbohydrates, such as fruit juice or glucose tablets, is the recommended first step to reverse hypoglycemia. Administering glucagon intramuscularly is usually reserved for severe hypoglycemia when the client is unconscious or unable to swallow. Checking the client's blood pressure is important but not the primary intervention for hypoglycemia. Notifying the healthcare provider can be done after the immediate management of hypoglycemia.

3. While teaching a group of adults about health promotion activities, a nurse identifies a behavior that poses the most significant risk factor for the development of skin cancer. Which behavior should the nurse address?

Correct answer: B

Rationale: Using tanning beds is the most significant risk factor for developing skin cancer. Ultraviolet (UV) radiation from tanning beds damages the skin and increases the risk of skin cancer. Consuming a high-fat diet, smoking cigarettes, and drinking alcohol are unhealthy behaviors but are not directly linked to the development of skin cancer like UV exposure from tanning beds.

4. When performing an admission assessment of a client diagnosed with a brain tumor, which question is most important for the nurse to ask the client?

Correct answer: D

Rationale: The correct answer is D. When assessing a client diagnosed with a brain tumor, asking about seizures is crucial because they can be a common symptom associated with brain tumors. Seizures in this context could provide valuable information regarding the progression and impact of the brain tumor on the client's neurological status. Choices A, B, and C are important questions in a general assessment, but when specifically focusing on a client with a brain tumor, inquiring about seizures takes priority due to its direct relevance to the condition.

5. A client is leaving the hospital against medical advice (AMA) and voluntarily signs the AMA form. Which nursing action is essential prior to the client leaving?

Correct answer: A

Rationale: Removing the client's peripheral IV access is essential before the client leaves against medical advice to prevent complications such as infection, thrombosis, or bleeding. Administering pain relief medication (choice B) can be important but not essential at this point. Obtaining neurological vital signs (choice C) is not specifically required before the client leaves. Providing the client with the hospital's phone number (choice D) may be helpful but is not as essential as ensuring the safe removal of IV access.
