An oral thermometer is usually color-coded

Correct Answer: A

Rationale: The correct answer is A: Green or blue. Oral thermometers are color-coded in green or blue to indicate that they are designed for oral use, making them easily distinguishable from other types of thermometers. Green or blue color-coding helps users quickly identify the appropriate thermometer for oral temperature readings. Incorrect choices: B: Red or orange - Red or orange color-coding is not typically used for oral thermometers. C: Black or white - Black or white color-coding is not commonly associated with oral thermometers. D: White or gray - White or gray color-coding is not standard for oral thermometers.

Correct Answer: A

Rationale: The correct answer is A: Brown and soft. Stool should normally be brown due to the breakdown of bile pigments. Soft consistency indicates adequate hydration and fiber intake. Black stool (choice B) may indicate upper gastrointestinal bleeding. Loose stool (choice C) may suggest diarrhea. Red stool (choice D) may indicate lower gastrointestinal bleeding. Therefore, choice A is correct as it aligns with the typical characteristics of healthy stool.

Correct Answer: A

Rationale: The correct answer is A: Straight. A straight catheter is inserted to drain urine from the bladder several times a day and is then removed after the urine is drained. This type of catheter is used for intermittent catheterization. Explanation: Straight catheters are designed for short-term use, allowing the bladder to empty completely during each catheterization. Summary: B: Indwelling catheters are left in the bladder for a longer period and do not need to be removed and reinserted each time. C: Condom catheters are external catheters used for males and do not involve insertion into the bladder. D: Texas catheters are not commonly used for intermittent catheterization.

Correct Answer: A

Rationale: The correct answer is A, the groin. Fungal infections commonly occur in warm, moist areas of the body, like the groin, due to the ideal environment for fungal growth. Fungi thrive in areas with limited airflow and increased moisture, making the groin a prime location. Fungal infections on the head, arms, or cheeks are less common because these areas are typically drier and less conducive to fungal growth. Thus, the groin is the most likely site for fungal infections to occur.

Correct Answer: C

Rationale: The correct answer is C: Supplies oxygen to body cells. The respiratory system functions to intake oxygen from the air and release carbon dioxide, ensuring cells have oxygen for energy production. This process occurs through breathing and gas exchange in the lungs. Choice A is incorrect as regulating body temperature is primarily the function of the skin and sweat glands. Choice B is incorrect as pumping blood throughout the body is the function of the circulatory system. Choice D is incorrect as providing the body with shape and structure is the role of the skeletal system.
