An oral thermometer is usually color-coded

Correct Answer: A

Rationale: The correct answer is A. An oral thermometer is usually color-coded with green or blue to indicate that it is intended for oral use. This color-coding helps prevent using the thermometer in the wrong way, such as using it rectally instead of orally. Red or orange (choice B) is commonly used for rectal thermometers, while black or white (choice C) and white or gray (choice D) are not typically associated with oral thermometers. Therefore, the correct answer is A as it aligns with industry standards and best practices for oral thermometer color-coding.

Correct Answer: A

Rationale: The correct answer is A because normal stool should be brown in color due to the breakdown of bile pigments. It should also be soft, indicating a healthy level of moisture and fiber content. Black stool (choice B) can indicate bleeding in the upper digestive tract. Brown and loose stool (choice C) can indicate a lack of proper digestion or absorption. Red and formed stool (choice D) can indicate bleeding in the lower digestive tract. Therefore, choice A is the best representation of normal, healthy stool characteristics.

Correct Answer: A

Rationale: The correct answer is A: Straight catheter. A straight catheter is inserted into the bladder to drain urine and then removed immediately after, making it suitable for intermittent catheterization. Indwelling catheters (B) are left in place for continuous drainage. Condom catheters (C) are external devices for males. Texas catheters (D) are also external devices. The key is the need to insert and remove the catheter each time, which aligns with the purpose of a straight catheter.

Correct Answer: A

Rationale: The correct answer is A: The groin. Fungal infections commonly occur in warm, moist areas of the body, making the groin a common site due to the skin folds and sweat. Fungi thrive in these conditions. The head, arms, and cheeks are less favorable environments for fungal growth compared to the groin. Fungal infections on the head are less common due to the lack of moisture, while the arms and cheeks are typically exposed to air and have drier skin, making them less susceptible to fungal infections.

Correct Answer: C

Rationale: The correct answer is C because the respiratory system supplies oxygen to body cells. This process occurs through breathing, where oxygen is inhaled into the lungs and then transferred to the bloodstream to be delivered to cells for energy production. Option A is incorrect as regulating body temperature is primarily controlled by the skin and sweat glands. Option B is incorrect as pumping blood throughout the body is the function of the circulatory system. Option D is incorrect as giving the body shape and structure is the function of the skeletal system.
