Correct Answer: C

Rationale: Choice C is the correct answer. When performing a sterile dressing change, it is essential to use clean gloves to remove soiled dressings and sterile gloves and supplies for applying the new dressing. This helps maintain aseptic technique and reduce the risk of introducing pathogens to the wound. Choices A, B, and D involve incorrect use of sterile and clean supplies, which can compromise the sterility of the procedure and increase the risk of infection.

Correct Answer: B

Rationale: The most important action to ensure patient safety when administering a blood transfusion is to verify the patient's identity with two identifiers before starting the transfusion. This step is crucial to prevent transfusion errors, such as giving the blood to the wrong patient. Checking vital signs, ensuring timely administration, and confirming informed consent are also important aspects of blood transfusion safety but verifying the patient's identity is the highest priority to prevent errors.

Correct Answer: B

Rationale: When a client expresses doubts about a procedure after signing the consent form, it is crucial to stop the surgery and consult with the surgeon. This is important to ensure that the client's concerns are addressed, and there is a clear understanding of the procedure. Reassuring the client and proceeding with the surgery (choice A) may violate the client's autonomy and right to informed consent. Proceeding with the surgery but documenting the concerns (choice C) is not sufficient as the client's doubts should be resolved before proceeding. Postponing the surgery until further clarification is provided (choice D) may be necessary, but the immediate step should be to consult with the surgeon to address the client's concerns.

Correct Answer: A

Rationale: The most appropriate assessment question in this scenario is asking the patient, 'What activities, if any, has your pain prevented you from doing?' This question helps the healthcare provider understand how pain is impacting the patient's daily activities and mobility, providing valuable insight into the limitations caused by the pain. Choice B focuses on pain medication effectiveness, which is not directly related to mobility assessment. Choice C aims at pain intensity assessment but does not directly address mobility issues. Choice D suggests a solution rather than gathering information about the current impact of pain on mobility.

Correct Answer: B

Rationale: The correct answer is B. Placing a gait belt around the patient for support is the safest option when assisting a patient to stand from a sitting position. This belt provides stability and support, reducing the risk of falls or injuries during the transfer. Choices A, C, and D are incorrect. Allowing the patient to pull up on the nurse's arm (Choice A) may lead to instability and compromise safety. Having the patient push off the chair with their hands (Choice C) might not provide sufficient support, especially for patients who require assistance. Asking the patient to lift themselves up without support (Choice D) can be dangerous and increase the risk of falls.
