The circadian rhythm is

Correct Answer: C

Rationale: The circadian rhythm is the 24-hour biological cycle that regulates various physiological processes such as sleep-wake cycles, hormone production, and body temperature. It is synchronized with the day-night cycle. Choice A and B are incorrect as they focus solely on rest and sleep, not the full range of biological processes regulated by the circadian rhythm. Choice D is incorrect as it specifically refers to the day-night cycle, which is just one aspect of the circadian rhythm. The correct answer, C, encompasses the comprehensive definition of the circadian rhythm as a 24-hour biological cycle.

Correct Answer: A

Rationale: The correct answer is A because dressing the weak side first allows for easier movement and reduces strain on the weaker side. By starting with the weak side, it ensures better support and stability for the resident. Choice B is incorrect as it may cause imbalance. Choice C is incorrect as using the term "bad side" can be disempowering. Choice D is incorrect because the order of dressing can impact the resident's comfort and safety.

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.
