Basic Principles of Long-Term Patient Care Developing a Therapeutic Community Questions
Question 1 of 5
If a resident consumes ½ cup of a fluid how many milliliters (mL) has he consumed?
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.
Question 2 of 5
A yeast infection is a type of vaginitis that is caused by a fungus known as
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.
Question 3 of 5
One function of the blood is to
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.
Question 4 of 5
What is the protective substance that covers the ends of bones?
Correct Answer: A
Rationale: The correct answer is A: Cartilage. Cartilage is the protective substance that covers the ends of bones, providing cushioning and reducing friction during movement. It also helps in absorbing shock and maintaining joint flexibility. Collagen (B) is a protein found in connective tissues but not the primary substance covering bone ends. Hormones (C) are signaling molecules that regulate various bodily functions, not related to bone protection. Minera (D) is a misspelling and not a relevant substance for bone protection.
Question 5 of 5
Thyroid hormones primarily regulate the following:
Correct Answer: D
Rationale: The correct answer is D: Metabolism and growth. Thyroid hormones, such as T3 and T4, play a crucial role in regulating metabolism by influencing the body's energy production and consumption. They also help in the growth and development of various tissues and organs. This is supported by scientific research and physiological understanding. Explanation for other choices: A: Heart rate and respiration - While thyroid hormones can indirectly influence heart rate and respiration through their effects on metabolism, they are not the primary regulators of these functions. B: Bile production and potassium - Thyroid hormones do not have a direct role in regulating bile production or potassium levels in the body. C: Kidney and liver function - While thyroid hormones can affect kidney and liver function to some extent, their primary role lies in metabolism and growth regulation.
