Correct Answer: C

Rationale: The correct information that the nurse should include in the teaching about a CPAP device is that it delivers a preset amount of airway pressure throughout the breathing cycle. This consistent positive airway pressure helps keep the airway open during both inspiration and expiration. Choice A is incorrect as CPAP does not deliver pressure only at the beginning of each breath. Choice B is incorrect because CPAP provides a constant level of pressure without continuous adjustments throughout the cycle. Choice D is incorrect as CPAP does not provide positive pressure at the end of each breath; instead, it maintains a continuous positive pressure.

Correct Answer: A

Rationale: In the scenario of a client experiencing prolonged seizures, such as status epilepticus, the priority is to administer a benzodiazepine to stop the seizure activity. Diazepam is the medication of choice for this situation due to its rapid onset of action and effectiveness in terminating seizures quickly. Lorazepam, although another benzodiazepine, is typically given through routes other than oral (PO) administration in emergency situations. Diltiazem is a calcium channel blocker used for cardiac conditions, not for seizure management. Clonazepam is a benzodiazepine, but it is usually not the first choice in the acute management of status epilepticus.

Correct Answer: B

Rationale: The correct answer is B: 'Consume high-calorie, high-protein foods.' Clients with COPD often have increased energy needs due to the work of breathing. Consuming high-calorie, high-protein foods can help provide the necessary energy and prevent weight loss. Choice A is incorrect because eating three large meals daily may lead to increased shortness of breath due to a full stomach. Choice C is incorrect because limiting caffeinated drinks is important, but the recommendation should focus on reducing intake, not specifying a number. Choice D is incorrect because drinking fluids during mealtime can lead to early satiety, making it difficult for the client to consume enough calories.

Correct Answer: D

Rationale: The nurse should encourage the client to attend a support group for individuals with burn injuries. Support groups can provide emotional support, promote acceptance of altered appearance, and help the client cope with the changes. Choice A is incorrect because it may not address the client's emotional needs. Choice B is incorrect as suggesting a timeline for cosmetic surgery may not be appropriate without considering the client's physical and emotional readiness. Choice C is incorrect as reconstructive surgery may not completely restore the client's previous appearance and may set unrealistic expectations.

Correct Answer: A

Rationale: A sodium level of 122 mEq/L indicates hyponatremia, which is characterized by decreased deep tendon reflexes. Hyponatremia leads to neurological symptoms such as altered reflexes. Choices B, C, and D are not typically associated with hyponatremia. Positive Trousseau's sign is related to hypocalcemia, hypoactive bowel sounds can be seen in paralytic ileus or decreased peristalsis, and sticky mucous membranes are not specific findings related to sodium imbalances.
