Which of the following is a function of the respiratory system?

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.

Correct Answer: B

Rationale: The correct answer is B because taking the resident to a private area addresses the behavior discreetly, respecting the resident's dignity and privacy. It allows for a calm and appropriate response without causing embarrassment. Letting other residents know (A) violates the resident's privacy. Informing others negatively about the resident (C) is disrespectful and unprofessional. Reprimanding loudly (D) may escalate the situation and be humiliating for the resident.

Correct Answer: A

Rationale: The BRAT diet consists of bananas, rice, applesauce, and toast, which are low-fiber, binding foods helpful in easing digestion during diarrhea. Bananas are rich in potassium and easy to digest, rice helps firm up stools, applesauce is gentle on the stomach, and toast provides bland carbohydrates. This diet helps alleviate diarrhea symptoms by providing easily digestible and soothing foods. Choices B, C, and D are incorrect as the BRAT diet is not designed for weight gain, weight loss, or managing numbness and tingling symptoms.

Correct Answer: C

Rationale: The correct answer is C: Following instructions for intake and output measurement carefully. This is crucial for monitoring fluid balance in dialysis patients. Tight sleeves (A) can restrict blood flow, checking blood pressure on the access arm (B) can cause inaccurate readings, and encouraging pressure on the access arm (D) can harm the dialysis access site. Monitoring intake and output ensures proper fluid management and helps prevent complications.

Correct Answer: C

Rationale: The correct answer is C: Eating and drinking. Activities of daily living (ADLs) refer to basic self-care tasks essential for daily functioning. Eating and drinking are fundamental ADLs necessary for survival. Mending torn clothing (A) is not an ADL as it is not essential for basic functioning. Removing soiled bed linens (B) is considered an instrumental activity of daily living (IADL) rather than a basic ADL. Emptying the trash (D) is also an IADL and not directly related to personal care.
