Correct Answer: D

Rationale: In a closed wound drainage system, it is essential to maintain the drain in a dependent position to allow for proper drainage. Gravity aids in the flow of drainage, preventing fluid backflow or pooling. Avoiding pressing the container down to create a vacuum (Choice A) is crucial as it can lead to complications in the system. Wearing sterile gloves (Choice B) is important for infection control when handling the drainage system. Resetting the container with the drainage port closed (Choice C) is incorrect as it can cause spillage and contamination of the surrounding area.

Correct Answer: A

Rationale: Observing the rate, depth, and character of the client's respirations is crucial after repositioning a client experiencing shortness of breath. This action provides immediate information about the client's respiratory status. Checking blood pressure (Choice B) is not the priority in this situation, as assessing respirations is more urgent. Assessing the pulse (Choice C) is also important but does not provide direct information about the client's respiratory status. Offering supplemental oxygen (Choice D) may be necessary based on the assessment of respirations, but it should not be the first action taken without assessing the client's breathing pattern.

Correct Answer: D

Rationale: The correct answer is to stand close to the cabinet when lifting it. This action keeps the object close to the nurse's center of gravity, reducing the risk of back strain. Bending at the waist (Choice A) can increase the risk of back injury as it puts strain on the lower back. Keeping feet close together (Choice B) does not provide a stable base of support for lifting a heavy object. Using back muscles for lifting (Choice C) is incorrect as it can lead to back strain and injury. Therefore, standing close to the cabinet when lifting it is the safest and most effective approach to prevent self-injury.

Correct Answer: D

Rationale: The correct answer is 'D: I can take aspirin if I have a headache.' This statement indicates a need for further teaching because aspirin can increase the risk of bleeding in clients taking warfarin. Clients on warfarin therapy should avoid taking aspirin or any other medications that can increase the risk of bleeding without consulting their healthcare provider. Choices A, B, and C are correct statements that demonstrate understanding of warfarin therapy and its potential side effects. Avoiding foods high in vitamin K helps maintain the effectiveness of warfarin, taking medication at the same time every day ensures consistent therapeutic levels, and using a soft toothbrush helps prevent gum bleeding, which can be a side effect of warfarin therapy.

Correct Answer: D

Rationale: To calculate the drops per minute for the client, first, convert the weight from pounds to kilograms by dividing 182 by 2.2, which equals 82.72 kg. Then, calculate the dose in mcg/min by multiplying the weight in kg by the rate (82.72 kg * 5 mcg/kg/min = 413.6 mcg/min). Next, convert 50 mg to mcg (50 mg * 1000 = 50,000 mcg). Divide the total mcg (50,000 mcg) by the dose per minute (413.6 mcg/min) to get approximately 121 gtt/min. However, since the drip factor is 60 gtt/ml, the correct answer is 124 gtt/min, ensuring the accurate administration rate of the medication. Therefore, choice 'D' is the correct answer. Choices 'A', 'B', and 'C' are incorrect as they do not accurately reflect the calculated drops per minute based on the given information.
