Hypotension
Nausea
Dysphagia
Confusion
The Correct Answer is D
A: Hypotension is not an early sign of hypoxemia. It can occur in severe cases but is not typically an initial indicator.
B: Nausea is not a common sign of hypoxemia. It may occur due to other factors but is not directly related to low oxygen levels.
C: Dysphagia, or difficulty swallowing, is not a sign of hypoxemia. It is related to swallowing disorders rather than oxygen levels.
D: Confusion is an early sign of hypoxemia. Low oxygen levels can affect brain function, leading to confusion and other cognitive changes.

Correct Answer is B
Explanation
A: Obtaining a chest x-ray is important for diagnosing potential complications but is not the immediate first action to improve oxygen saturation.
B: Raising the head of the bed helps improve lung expansion and oxygenation. It is a quick and effective first step to increase oxygen saturation.
C: Administering a prescribed analgesic can help with pain management but does not directly address the low oxygen saturation.
D: Administering oxygen at 2 L/min is important but should follow the initial step of raising the head of the bed to optimize breathing.
Correct Answer is C
Explanation
The correct answer is C.
A: Consulting a dietitian is a beneficial order for a patient with a pressure ulcer. Proper nutrition, especially adequate protein intake, is crucial for wound healing. A dietitian can help ensure the patient receives the necessary nutrients to support tissue repair and recovery.
B: Applying a hydrogel dressing is appropriate for a clean, granulating Stage II pressure ulcer. Hydrogel dressings maintain a moist wound environment, which promotes healing and provides pain relief. They are suitable for wounds with minimal to moderate exudate.
C: Cleaning the wound with hydrogen peroxide is not recommended for a healing pressure ulcer. Hydrogen peroxide can damage healthy granulating tissue and delay the healing process. It is better to use saline or a wound cleanser that does not harm the new tissue.
D: Using a low-air-loss therapy unit is beneficial for patients with pressure ulcers. These units help reduce pressure on the skin, improve circulation, and prevent further skin breakdown. They are an effective part of pressure ulcer management.
