Answer and Explanation

The Correct Answer is D

B: A simple face mask provides a higher concentration of oxygen than a nasal cannula but may not deliver a high enough concentration for a client experiencing severe respiratory distress.
C: A Venturi mask can provide a precise and adjustable concentration of oxygen but may not deliver the highest concentration needed in this scenario.
D: A nonrebreather mask can deliver the highest concentration of oxygen (up to 100%) and is the most appropriate choice for a client experiencing severe difficulty breathing.

C. Increased metabolic rate occurs with age, and increasing body temperature: This statement is incorrect. In general, metabolic rate tends to decrease with age, which can contribute to decreased heat production in older adults.
D. Sweat gland activity is increased with age: This statement is incorrect. Sweat gland activity tends to decrease with age, leading to decreased sweating and potential challenges in cooling the body during hot conditions.
