Correct Answer: B

Rationale: Repositioning the client every 2 hours is the most appropriate action to prevent further skin breakdown in a client with a pressure ulcer on the sacrum. This practice helps relieve pressure on the affected area, promoting circulation and reducing the risk of tissue damage. Applying a hydrocolloid dressing (Choice A) may be beneficial for wound healing but is not the initial preventive measure. Using a donut-shaped cushion (Choice C) can actually increase pressure on the sacrum and worsen the condition. Massaging the area around the ulcer (Choice D) can further damage delicate skin and tissues, leading to more harm instead of prevention.

Correct Answer: A

Rationale: The correct intervention for the nurse to implement in this scenario is to determine the client's sleep and activity pattern. By assessing the client's patterns, the nurse can identify factors contributing to the sleep issues and tailor appropriate interventions. Choice B is incorrect because prescribing medication without a comprehensive assessment is not the initial step. Choice C is unnecessary at this stage as the client's symptoms are likely related to stress rather than a neurological disorder. Choice D, while important, should come after understanding the client's sleep patterns to provide holistic care. Therefore, option A is the best choice to address the client's sleep difficulties and headaches effectively.

Correct Answer: B

Rationale: Irritation of nasal mucosa is a crucial finding that the nurse should report to the provider as it suggests potential complications with NG tube placement, such as improper positioning or mucosal damage. High potassium levels (Choice A) can be concerning but are not directly related to NG tube placement issues. Normal sodium levels (Choice C) and loose stools (Choice D) are common occurrences in clients receiving tube feedings and are not typically indicative of immediate complications that require urgent reporting.

Correct Answer: B

Rationale: Redirecting the client's attention is the appropriate nursing action in this scenario. When dealing with a confused client exhibiting grabbing behavior, redirection can help shift their focus to a more appropriate activity or object. Firmly telling the client not to grab may escalate the situation and create a confrontational environment, which is not recommended when caring for confused clients. The use of physical restraints should be a last resort and only implemented after all other strategies have been exhausted, as they can contribute to increased agitation and distress in older adults. Avoiding contact with the client is not a proactive approach to managing the behavior and may lead to feelings of neglect or abandonment in the client.

Correct Answer: A

Rationale: Collapsing the device when it is 1/2 to 2/3 full of air is the correct nursing action to ensure proper operation of a closed wound suction device (hemovac). This action maintains negative pressure, which is essential for proper suction and drainage of the wound. Emptying the device every 4 hours (Choice B) is not necessary as the focus should be on collapsing it appropriately. Replacing the device every 24 hours (Choice C) is not a standard practice unless indicated by the healthcare provider. Keeping the device above the level of the surgical site (Choice D) is not necessary for the device's proper operation; collapsing it to maintain negative pressure is the key action.
