Correct Answer: D

Rationale: The correct answer is D. For organ donation to be legally valid, the donor must sign consent documents in the presence of a witness. Choice A is incorrect because while discussing with family is important, it is not a legal requirement for organ donation. Choice B is incorrect as the organ donation process involves various steps and procedures that cannot begin immediately. Choice C is incorrect because organ donation typically requires consent and cooperation from the family if the donor is unable to provide consent.

Correct Answer: B

Rationale: The nurse's priority action should be to withhold the medication until the trough level is obtained. This is crucial to ensure accurate dosing based on the patient's levels. Administering the medication before the peak level is obtained (choice A) can lead to incorrect dosing. Administering the medication based on the previous trough level (choice C) may not reflect the current levels accurately. Ensuring that the medication is administered within 2 hours of the peak level (choice D) is not necessary for obtaining accurate peak and trough levels.

Correct Answer: B

Rationale: Emptying the colostomy bag when it is half full is the most important nursing action when caring for a patient with a colostomy. This practice helps prevent leakage, reduces the risk of skin irritation, and promotes patient comfort. Monitoring for signs of infection (Choice A) is essential but not as crucial as maintaining proper colostomy care. Encouraging the patient to eat smaller, more frequent meals (Choice C) can be beneficial for colostomy patients but is not as critical as ensuring timely emptying of the colostomy bag. Applying a skin barrier to prevent irritation (Choice D) is important, but ensuring timely emptying of the colostomy bag takes precedence in preventing complications associated with a colostomy.

Correct Answer: B

Rationale: The correct first step for the nurse to take in this situation is to ask the colleague if they intend to report the error. It is important to address the error promptly and directly with the colleague involved to ensure that the appropriate actions are taken to correct the mistake and prevent harm to the client. Completing an incident report, calling the healthcare provider, or notifying the supervisor can be done after discussing the error with the colleague. Immediate communication with the colleague directly involved in the error is crucial to address the situation effectively.

Correct Answer: B

Rationale: When a nurse observes a colleague behaving strangely, the best course of action is to report the behavior to the supervisor. Unusual behavior by a healthcare professional could compromise patient safety and should be addressed promptly. Ignoring the behavior (Choice A) could potentially lead to negative outcomes for patients. Asking the colleague directly (Choice C) may not be appropriate if the behavior poses a risk. Discussing the behavior with other colleagues (Choice D) may not directly address the issue and could lead to gossip rather than a resolution.
