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 helps distribute their weight evenly, preventing the wheelchair from tipping forward. This ensures stability and reduces the risk of falls or accidents. Choice A is incorrect because going down a ramp forward could lead to loss of control. Choice B is wrong as leaving the wheels unlocked is unsafe and may cause the wheelchair to move unexpectedly. Choice C is irrelevant to the guideline for wheelchair safety.

Correct Answer: B

Rationale: The correct answer is B, reduced physical activity affects appetite. As people age, their metabolism slows down and they tend to become less active, leading to a decrease in appetite. This can result in the elderly not consuming enough nutrients, causing nutritional problems. A is incorrect because increased appetite is not a common issue for the elderly. C is incorrect because special diets for the elderly are designed to meet specific nutritional needs, not overwhelm them with too many choices. D is incorrect because the nutritional requirements and challenges for the elderly are different due to factors such as reduced absorption and changing dietary needs.

Correct Answer: D

Rationale: To convert ounces to milliliters, we need to know that 1 ounce is approximately 29.5735 mL. So, 4 ounces x 29.5735 mL = 118.294 mL. Rounded to the nearest whole number, the resident consumed 120 mL. Choice A is incorrect as it miscalculates the conversion. Choice B is incorrect as it is too low. Choice C is incorrect as it overestimates the amount consumed.

Correct Answer: C

Rationale: Rationale for correct answer (C): A lack of privacy and stress can affect urination as it can lead to inhibition of the relaxation response needed for the bladder to empty fully. Privacy and relaxation are crucial for efficient urination. Stress can also trigger the fight-or-flight response, causing the bladder muscles to contract and prevent proper voiding. Hence, C is the correct statement. Summary of why other choices are incorrect: A: Indwelling catheters can affect muscle tone as they may lead to muscle atrophy and loss of muscle tone in the pelvic floor. B: Fluids high in sodium may actually decrease urinary output due to increased retention of water in the body. D: The bladder's capacity decreases with age, leading to more frequent urination rather than less.

Correct Answer: C

Rationale: The correct answer is C: Skin. The skin is the largest organ in the human body by surface area. It covers the entire body and serves as a protective barrier against external elements. The heart (A), lungs (B), and kidneys (D) are all vital organs but are smaller in size compared to the skin. The heart is responsible for pumping blood, the lungs for oxygen exchange, and the kidneys for filtering waste products from the blood. However, in terms of sheer surface area and coverage, the skin is the largest organ.
