Correct Answer: A

Rationale: Assessing skin turgor by gently pinching the skin on the forearm is a reliable method to check for dehydration in elderly patients. When the skin is slow to return to its original position, it indicates dehydration. While assessing for dry mucous membranes is also important, checking skin turgor is a more direct method for dehydration assessment. Checking for orthostatic hypotension is more related to circulation status than dehydration. Measuring daily weights is helpful to monitor fluid balance but may not be as immediate or direct in detecting dehydration in elderly patients.

Correct Answer: D

Rationale: In the preoperative phase, determining what the client knows about the surgery is the priority. This action helps address misconceptions, provide necessary information, and ensure the client's understanding and cooperation. Choices A, B, and C are important aspects of preoperative care but assessing the client's knowledge about the surgery takes precedence to alleviate fears, enhance communication, and optimize outcomes.

Correct Answer: C

Rationale: The correct answer is C: Low chairs without armrests. This observation should be addressed by the nurse to promote a safe environment for the older adult client. Low chairs without armrests increase the risk of falls as they can be challenging for older adults to sit down on or get up from. Addressing this issue can help prevent falls and promote safety. Choices A, B, and D are not as crucial for promoting a safe environment compared to the risk posed by low chairs without armrests.

Correct Answer: C

Rationale: The correct precaution for a nurse caring for a client with shigella-induced diarrhea is to wash hands before and after client care. Shigella is a highly contagious bacterium that spreads through contaminated food, water, or contact with infected individuals. While wearing gloves is important when directly handling bodily fluids, hand hygiene is crucial in preventing the transmission of the infection. Wearing a mask or using an N95 respirator is not necessary for preventing the spread of shigella, as it primarily spreads through the fecal-oral route rather than through respiratory droplets.
