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. When the nurse enters the room to change the dressing of a male client with cancer, he asks, 'Have you ever been with someone when they died?' What is the nurse's best response to him?

Correct answer: A

Rationale: The correct response is to acknowledge the client's question and open the door for further discussion by asking if they have questions about dying. This approach allows the nurse to address the client's concerns and fears, promoting open communication and providing emotional support. Choices B and C do not encourage further dialogue about the client's feelings and concerns regarding death. Choice D briefly acknowledges the question but does not actively invite the client to express their thoughts and emotions regarding dying.

3. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 4 liters per minute via nasal cannula. The client becomes lethargic and confused. What action should the nurse take first?

Correct answer: A

Rationale: In this scenario, the priority action for the nurse is to decrease the oxygen flow rate. Clients with COPD are sensitive to high levels of oxygen and can develop oxygen toxicity, leading to symptoms like lethargy and confusion. Decreasing the oxygen flow rate helps prevent this complication. Increasing the oxygen flow rate would worsen the client's condition. Encouraging coughing and deep breathing may not address the immediate issue of oxygen toxicity. While monitoring the client's oxygen saturation level is important, taking action to address the oxygen toxicity by decreasing the flow rate is the priority in this situation.

4. A 9-year-old received a short arm cast for a right radius. To relieve itching under the child's cast, which instructions should the nurse provide to the parents?

Correct answer: A

Rationale: The correct answer is A: 'Blow cool air from a hairdryer under the cast.' Blowing cool air can help relieve itching without damaging the cast or causing injury. Choice B, twisting the cast back and forth, can lead to discomfort, skin irritation, or even injury. Choice C, shaking powder into the cast, can create a mess, increase the risk of skin issues, and interfere with proper healing. Choice D, pushing a pencil under the cast edge, is dangerous as it can cause injury to the child's skin or the underlying tissues. Therefore, the safest and most effective option to relieve itching under the cast is to blow cool air from a hair dryer.

5. A client with a C-6 spinal injury changes to a breathing pattern of shallow respirations and dyspnea twelve hours after the causative incident. The nurse should notify the healthcare provider and implement which intervention?

Correct answer: B

Rationale: In a client with a C-6 spinal injury exhibiting shallow respirations and dyspnea, these signs could indicate respiratory compromise and potential respiratory failure. Intubation with an endotracheal tube may be necessary to secure the airway and support adequate oxygenation. Placing the client in reverse Trendelenburg position, administering pain medication, or instructing on deep breathing exercises would not directly address the urgency of the respiratory distress in this situation, making them incorrect choices.
