Correct Answer: B

Rationale: When caring for a client experiencing delirium, it is essential to identify the underlying causative condition or illness. Delirium can be caused by various factors such as infections, medication side effects, dehydration, or underlying health conditions. By identifying the root cause, appropriate treatment can be provided. Controlling behavioral symptoms with low-dose psychotropics (Choice A) may be considered in some cases but is not the primary essential step. Manipulating the environment to increase orientation (Choice C) can help manage symptoms but does not address the underlying cause. Decreasing or discontinuing all previously prescribed medications (Choice D) should only be done under medical supervision, as some medications may be necessary for the client's well-being.

Correct Answer: A

Rationale: The correct answer is to maintain a patent airway and monitor for infection. These are crucial nursing interventions for patients with tracheostomies to ensure adequate oxygenation and prevent complications. Suctioning airway secretions and providing humidified oxygen can be part of the care plan but are not as essential as maintaining a patent airway. Educating the patient on self-care and tracheostomy cleaning is important for long-term management but is not as immediate as ensuring a patent airway and monitoring for infection. Changing tracheostomy ties daily is a specific task related to tracheostomy care but is not as critical as ensuring the airway is clear and infection-free.

Correct Answer: D

Rationale: In a situation where a verbal prescription for restraints is obtained for a client experiencing acute mania, the nurse should document the client's condition every 15 minutes. This frequent documentation allows for accurate monitoring of the client's condition, ensuring safety and compliance. Requesting a renewal of the prescription every 8 hours (Choice A) is not necessary as the focus should be on monitoring the client's condition. Checking the client's peripheral pulse rate every 30 minutes (Choice B) is not directly related to the need for restraints in this scenario. Obtaining a prescription for restraint within 4 hours (Choice C) is not a priority when a verbal prescription is already obtained and immediate action is needed for the client's safety.

Correct Answer: C

Rationale: When dealing with a physically assaultive client, the initial priority is to focus on restoring the client's self-control and preventing further escalation. Restricting the client to the room (choice A) may escalate the situation and is not the initial priority. Placing the client under one-to-one supervision (choice B) is important but comes after ensuring the client's self-control. Clearing the immediate area of other clients (choice D) is essential for safety but is not the initial priority when compared to restoring the client's self-control.

Correct Answer: A

Rationale: The correct answer is to instruct the older adult client to eat a light snack before bedtime. This is beneficial as it helps prevent hunger, which can disrupt sleep. Choice B is incorrect as staying in bed for a prolonged time if unable to fall asleep can lead to frustration and worsen insomnia. Choice C is incorrect as taking a 1-hour nap during the day can interfere with the ability to fall asleep at night. Choice D is incorrect as performing exercises prior to bedtime can increase alertness and make it harder to fall asleep.
