Correct Answer: A

Rationale: The correct action to take first when observing blue fingers in a client with wrist restraints is to loosen the right wrist restraint. Blue fingers indicate compromised circulation, and loosening the restraint can help restore blood flow to the area. Applying a pulse oximeter (Choice B) or palpating the right radial pulse (Choice D) may be necessary following the loosening of the restraint to assess the client's oxygen saturation and pulse. Comparing hand color bilaterally (Choice C) is important but not the immediate action needed when a circulation issue is noted in one hand.

Correct Answer: A

Rationale: Having the client demonstrate the procedure is the most appropriate action to evaluate understanding within the psychomotor domain of learning. This allows the instructor to assess the client's ability to perform the skill, which is a key aspect of this domain. Choice B, explaining the procedure again, focuses on the cognitive domain rather than the psychomotor domain. Choice C, asking the client to describe the procedure, pertains more to the verbal or cognitive domain of learning. Choice D, observing the client watching a video on the procedure, does not directly assess the client's ability to perform the skill in the psychomotor domain.

Correct Answer: D

Rationale: Information about transmission-based precautions is essential for infection control and continuity of care.

Correct Answer: A

Rationale: The correct answer is to wear a gown when caring for the client. Shigellosis is highly contagious, and contact precautions are essential to prevent the spread of infection. Wearing gloves alone may not provide adequate protection as the client's diarrhea can contain infectious pathogens that can easily spread. Standard precautions include hand hygiene, but specific precautions for shigellosis require wearing a gown to protect against contact with infectious material. Wearing a mask and face shield are not necessary for shigellosis, as the primary mode of transmission is through the fecal-oral route, and these precautions are not indicated for this type of transmission.

Correct Answer: A

Rationale: The correct statement for the nurse to make to the client is to 'Donate autologous blood before the surgery.' Autologous blood donation involves collecting and storing the client's own blood for potential use during surgery, which significantly reduces the risk of transfusion-related infections. This option directly addresses the client's concern about infection risk. Requesting a specific blood type from a donor (Choice B) is not as effective in reducing infection risk compared to autologous blood donation. Using blood from a family member (Choice C) carries the risk of transfusion reactions and infections due to compatibility issues. Accepting allogeneic blood without concerns (Choice D) does not address the client's specific concern about infection risk and is not the most appropriate option in this situation.
