What temperature should the lotion be for a back massage?

Correct Answer: A

Rationale: The correct temperature for lotion in a back massage should be warm. Warm lotion helps to relax muscles, improve circulation, and enhance the overall massage experience. Hot lotion can potentially burn the skin, while cold or icy lotion can be uncomfortable and ineffective in promoting relaxation. Warm lotion allows for easier application and absorption into the skin, aiding in the smoothness of the massage strokes and maximizing the therapeutic benefits. Therefore, choice A is the most suitable option for a back massage.

Correct Answer: C

Rationale: The correct answer is C because the length of time the reagent strip is left dipped in urine affects the accuracy of the test results. Allowing the strip to stay in the urine for too long or too short a time can lead to incorrect readings. Option A is incorrect as it does not impact the testing process. Option B is also incorrect as expired strips may give inaccurate results. Option D is incorrect as the color of the urine does not determine the accuracy of the test, but rather the duration of exposure to the reagent strip.

Correct Answer: C

Rationale: The correct answer is C: Candida albicans. This fungus is the most common cause of yeast infections in the vaginal area. Candida albicans is a type of fungus that naturally resides in the body, but can overgrow in certain conditions, leading to an infection. Staphylococcus (choice A) and Streptococcus (choice D) are bacteria, not fungi, and are not typically associated with yeast infections. Pseudomonas (choice B) is also a bacterium and not the causative agent of yeast infections. Therefore, based on the nature of yeast infections and the known causative agent, Candida albicans is the correct choice.

Correct Answer: C

Rationale: The correct answer is C: Control pH levels. Blood helps maintain a stable pH level in the body by acting as a buffer system to prevent drastic changes in acidity or alkalinity. This is crucial for proper function of enzymes and other biochemical processes. Incorrect choices: A: Remove oxygen from the cells - This is incorrect as blood carries oxygen to cells, not removes it. B: Control blood vessel size - While blood vessels can regulate their size, it is not the primary function of blood. D: Increase body temperature - Blood does contribute to temperature regulation through circulation, but its primary role is not to increase body temperature.

Correct Answer: A

Rationale: The correct answer is A: Cartilage. Cartilage is the protective substance that covers the ends of bones. It acts as a cushion between bones, reducing friction and preventing wear and tear. Collagen is a protein found in connective tissues but is not the primary substance covering bone ends. Hormones and minerals do not directly protect the ends of bones.
