Correct Answer: B

Rationale: The correct answer is B: 'Avoid smoking and open flames near oxygen.' This information is crucial to prevent fire hazards when using home oxygen therapy. Smoking and open flames near oxygen can lead to serious accidents. Choice A is incorrect because increasing the oxygen flow rate during activity without healthcare provider guidance can be dangerous. Choice C is incorrect as oxygen tanks should be stored in a well-ventilated area, not necessarily warm and dry. Choice D is incorrect as oxygen should not be turned off and on by the client, as it can affect the therapy's effectiveness and cause safety issues.

Correct Answer: B

Rationale: The correct answer is B: Decrease in elasticity. As individuals age, their skin tends to lose elasticity, becoming less flexible. This results in wrinkles and sagging skin. Option A, increase in oil production, is not typically an expected integumentary change in older adults. Option C, increase in pigmentation, may occur due to sun exposure or age spots but is not a universal change. Option D, decrease in moisture levels, is not a primary integumentary change associated with aging.

Correct Answer: D

Rationale: The correct answer is D: Chronic conditions. Chronic conditions, such as diabetes or immune suppression, can compromise the immune system, making individuals more susceptible to infections. Frequent handwashing (Choice A) is actually a protective measure against infections. Increased mobility (Choice B) and high blood pressure (Choice C) are not directly associated with an increased risk for infections.

Correct Answer: B

Rationale: The correct answer is B: Increased hematocrit. Increased hematocrit indicates hemoconcentration, which is a sign of fluid volume deficit. When there is a decrease in fluid volume in the body, the blood becomes more concentrated, leading to an increase in hematocrit levels. Choices A, C, and D are incorrect because decreased BUN levels, increased white blood cell count, and decreased hematocrit are not indicative of fluid volume deficit.

Correct Answer: C

Rationale: The correct instruction for a client using a metered-dose inhaler (MDI) is to hold the inhaler 1-2 inches from the mouth. This distance allows for the proper delivery of the medication into the lungs. Choice A is incorrect because the duration of inhalation can vary depending on the medication, and 1 second may not be adequate. Choice B is incorrect as shaking the inhaler vigorously is not necessary for all MDIs and can lead to inaccurate dosing. Choice D is incorrect as the client should hold their breath for about 10 seconds after inhalation to allow the medication to deposit in the lungs.
