Which of the following is true of mechanical lifts?

Correct Answer: A

Rationale: The correct answer is A: Mechanical lifts help prevent injury to the body. This is true because mechanical lifts are designed to assist in lifting and transferring residents safely, reducing the risk of injury to both the resident and the caregiver. Mechanical lifts provide proper support and reduce strain on the caregiver's body. Explanation for other choices: B: It is safer for an NA to lift a resident without the help of a mechanical lift - This is incorrect because manual lifting without a mechanical lift increases the risk of injury to both the caregiver and the resident. C: There is only one kind of mechanical lift - This is incorrect as there are various types of mechanical lifts available, each designed for specific needs and situations. D: When using a mechanical lift - This choice is incomplete and does not provide a clear statement, making it incorrect.

Correct Answer: D

Rationale: The correct answer is D: Water. Water is essential for various bodily functions such as maintaining temperature, transporting nutrients, eliminating waste, and lubricating joints. Without water, humans can survive only a few days. Proteins, fats, and carbohydrates are important nutrients, but water is the most essential for life due to its critical roles in maintaining overall health and survival.

Correct Answer: A

Rationale: The correct answer is A because encouraging a resident to drink every time she sees him helps ensure regular fluid intake, preventing dehydration. This approach promotes hydration without overwhelming the resident with excessive fluids. Choice B is incorrect as insisting on a specific type of drink may not suit the resident's preferences. Choice C is incorrect as withholding fluids can lead to dehydration. Choice D is incorrect as leaving a carton of milk does not actively encourage the resident to drink and may not suit their preferences or dietary restrictions.

Correct Answer: C

Rationale: The correct answer is C: Women have a shorter urethra. This anatomical difference in women makes them more prone to urinary tract infections (UTIs) as bacteria have easier access to the bladder. The shorter urethra allows bacteria to travel up to the bladder more quickly. Choice A is incorrect as gonads are not related to UTIs. Choice B is incorrect as kidney function is not a direct cause of UTIs. Choice D is incorrect as urinary incontinence is a separate condition and not a direct reason for increased UTI risk in women.

Correct Answer: D

Rationale: The correct answer is D because as we age, the skin undergoes natural changes such as thinning and becoming more fragile. This is due to a decrease in collagen production and a reduction in the skin's ability to retain moisture. Thinning skin makes the elderly more susceptible to injuries and skin tears. A: Amount of fat and collagen increases - This is incorrect as aging leads to a decrease in collagen production and loss of fat in the skin. B: Pressure injuries occur - While pressure injuries can be common in older adults, it is not a normal age-related change of the integumentary system. C: Hair thickens - Hair thinning or loss is more common with age, not thickening. In summary, the normal age-related change of the integumentary system is skin becoming thinner and more fragile due to decreased collagen and moisture retention.
