The medical term for the absence of breathing is

Correct Answer: B

Rationale: The correct answer is B: Apnea. "Apnea" means the temporary absence of breathing. "Dyspnea" (A) refers to difficult or labored breathing, "Eupnea" (C) means normal breathing, and "Orthopnea" (D) is difficulty breathing when lying down. Apnea specifically indicates the complete cessation of breathing, making it the correct term for the absence of breathing.

Correct Answer: D

Rationale: The correct answer is D because creating a sign to hang near the bed to alert all staff is essential to ensure proper handling and collection of the 24-hour urine specimen. This step helps prevent any errors or miscommunication among staff members regarding the urine collection process. Explanation: A: Using a specimen kit is important but not the most crucial task when collecting a 24-hour urine specimen. B: Cleaning the perineal area is not directly related to the collection of a 24-hour urine specimen. C: Using strainers to filter all urine is not necessary for a 24-hour urine collection and may not be practical in this context. In summary, option D is the correct choice as it directly addresses the need for clear communication and coordination among staff members during the urine collection process.

Correct Answer: C

Rationale: The correct answer is C: A draining wound. Sterile dressings are necessary for draining wounds to prevent infection and promote proper healing. Draining wounds have an increased risk of contamination, making the use of sterile dressings essential. Choice A, a paper cut, typically does not require a sterile dressing as it is a minor wound. Choice B, an intact wound, does not require a sterile dressing unless there is a risk of infection. Choice D, a clean dry wound, also does not require a sterile dressing as long as it remains clean and dry. In summary, choice C is correct because draining wounds require sterile dressings to prevent infection, while the other choices do not necessarily require sterile dressings unless there are specific risk factors present.

Correct Answer: D

Rationale: The correct answer is D: Alveoli. Alveoli are tiny grape-like sacs within the lungs where gas exchange occurs. Oxygen is taken in from the air and carbon dioxide is released. Atria (A) are chambers in the heart, not the lungs. Axilla (B) refers to the armpit area. Arteries (C) are blood vessels that carry oxygenated blood away from the heart, not within the lungs. So, the correct answer is D because alveoli are specifically responsible for gas exchange in the lungs.

Correct Answer: C

Rationale: The correct answer is C: Osteoporosis. Osteoporosis is a bone disorder characterized by weakened bones, making them more prone to fractures from simple movements. The decreased bone density in osteoporosis leads to increased fragility. Turning in bed or sitting down can apply stress to the bones, resulting in fractures. Osteoarthritis (A) is a joint disorder, not directly related to bone fragility. Bursitis (B) is inflammation of the bursae, not directly linked to fractures. Tuberculosis (D) is a bacterial infection, not associated with bone fragility.
