Which of the following is a guideline for safely using a wheelchair?

Correct Answer: D

Rationale: The correct answer is D because positioning the resident's hips at the very back of the chair ensures stability and prevents the resident from sliding forward. This is crucial for maintaining proper posture and reducing the risk of falls. Choice A is incorrect because going down the ramp forward is unsafe. Choice B is incorrect since leaving the wheelchair wheels unlocked is dangerous. Choice C is irrelevant to wheelchair safety guidelines.

Correct Answer: B

Rationale: Step 1: Reduced physical activity in the elderly can lead to decreased appetite. Step 2: Decreased appetite can result in inadequate nutrient intake. Step 3: Inadequate nutrient intake can lead to various nutritional problems. Step 4: Therefore, reduced physical activity affecting appetite is one of the nutritional problems of the elderly. Summary: - Choice A is incorrect because increased appetite is not typically a common issue in the elderly. - Choice C is incorrect as having special diets doesn't necessarily lead to too many food choices. - Choice D is incorrect as nutritional needs and challenges often change with age, making elderly nutrition unique.

Correct Answer: D

Rationale: To convert ounces to milliliters, we know that 1 fluid ounce is approximately 29.5735 milliliters. Therefore, 4 ounces would be 4 x 29.5735 = 118.294 milliliters. Since we are asked for an approximation, the closest option is 120 mL (choice D). Choices A, B, and C are incorrect as they do not accurately represent the conversion from ounces to milliliters in this scenario.

Correct Answer: C

Rationale: The correct answer is C because privacy and stress can indeed affect urination. Privacy allows relaxation, which is essential for the bladder to empty properly. Stress can trigger the fight-or-flight response, leading to urinary retention or urgency. A: Indwelling catheters can impact muscle tone by causing the bladder muscles to weaken. B: Fluids high in sodium can actually decrease urinary output by increasing water retention. D: The bladder capacity decreases with age, leading to more frequent urination due to decreased elasticity.

Correct Answer: C

Rationale: The correct answer is C: Skin. The skin is the largest organ in the human body, covering an average of about 20 square feet. It serves as a protective barrier against external threats, regulates body temperature, and plays a role in sensation. The heart (A), lungs (B), and kidneys (D) are vital organs but do not surpass the skin in terms of size or surface area. Therefore, the skin is the correct choice for the largest organ in the human body.
