Which of the following is a helpful idea for dietary changes that may promote sleep?

Correct Answer: D

Rationale: The correct answer is D because eating meals earlier in the evening rather than just before bedtime allows for better digestion and prevents discomfort that may interfere with sleep. Eating heavy meals before bed can lead to indigestion and disrupt sleep. Fluid restrictions may cause dehydration, affecting sleep quality. Drinking soda before bedtime can lead to disturbances in sleep due to the caffeine and sugar content. By choosing option D, residents can optimize their digestion and promote better sleep quality.

Correct Answer: B

Rationale: The correct answer is B: 120 mL. To convert 1 cup to milliliters, we use the conversion factor 1 cup = 240 mL. Since the resident consumes ½ cup, we multiply 240 mL by 0.5 which equals 120 mL. The other choices are incorrect because they do not follow the correct conversion factor or mathematical calculation. Choice A (60 mL) would be the result if the resident consumed ¼ cup, choice C (30 mL) if he consumed 1/8 cup, and choice D (80 mL) is not a valid conversion based on the given information.

Correct Answer: C

Rationale: The correct answer is C: The length of time the reagent strip is left dipped in the urine. This is crucial because the reaction between the urine components and the reagent on the strip needs a specific amount of time to occur accurately. If the strip is not left in the urine for the correct duration, the results may be inaccurate. A: Touching the reagent bottle with the strip when reading is incorrect because it does not impact the accuracy of the test results. B: Using strips that have not expired is important, but not the most critical factor in the testing process. D: The color of the urine when testing it is also not as important as the duration of time the strip is dipped in the urine for accurate results.

Correct Answer: C

Rationale: The correct answer is C: Candida albicans. Candida albicans is a fungus known to cause yeast infections. It is a common cause of vaginal yeast infections. Staphylococcus (A) and Streptococcus (D) are bacteria, not fungi, and are not associated with yeast infections. Pseudomonas (B) is a type of bacteria commonly found in soil, water, and plants, but it is not the cause of yeast infections. Therefore, the correct answer is Candida albicans as it is the specific fungus responsible for yeast infections.

Correct Answer: C

Rationale: The correct answer is C: Control pH levels. Blood helps maintain the body's pH balance within a specific range, typically around 7.4, which is crucial for proper bodily functions. It does this by acting as a buffer, regulating the concentration of acids and bases in the body. In contrast, choice A is incorrect because blood actually transports oxygen to cells. Choice B is incorrect as blood vessel size is mainly controlled by the nervous system and hormones. Lastly, choice D is incorrect as blood does not directly regulate body temperature, which is primarily controlled by the hypothalamus in the brain.
