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

Correct Answer: B

Rationale: The correct answer is B: Prevents the loss of too much water. The integumentary system includes the skin, which acts as a barrier to prevent excessive water loss from the body. This is essential for maintaining proper hydration levels and overall health. Choices A, C, and D are incorrect because regulating hormone levels, allowing body movement, and providing an environment for fetal development are functions of other body systems like the endocrine, muscular, and reproductive systems, respectively.

Correct Answer: A

Rationale: The correct answer is A: Dry. Keeping the area dry before applying a prosthesis is crucial to ensure proper adhesion. Moisture can interfere with the bonding process, leading to potential slippage or discomfort. Dampness can also promote bacterial growth and skin irritation. Choices B, C, and D are incorrect because dampness (B) can compromise adhesion, cold (C) can affect comfort and blood circulation, and warmth (D) can increase sweat production and hinder adhesion. Therefore, ensuring the area is thoroughly dry is essential for optimal prosthetic application.

Correct Answer: B

Rationale: The correct answer is B: Use touch and smiles. This is because non-verbal communication, such as touch and smiles, can help the resident feel understood and connected despite the loss of verbal skills. It shows empathy and can provide comfort. A: Assuming the resident cannot understand may lead to feelings of isolation and neglect. C: Asking questions may be frustrating for the resident and cause further distress. D: Not involving the resident in activities can worsen feelings of isolation and decrease quality of life.

Correct Answer: C

Rationale: The correct answer is C because the immune system's main function is to protect the body against foreign substances and pathogens. It does this by identifying and neutralizing harmful invaders to maintain the body's health. A, B, and D are incorrect because maintaining blood sugar levels is primarily regulated by the endocrine system, regulating hormone production is done by the endocrine system, and body temperature regulation is controlled by the nervous system and endocrine system, not the immune system.

Correct Answer: B

Rationale: The correct answer is B because the function of an artificial airway is to keep the airway open for the lungs to perform air exchange. This is crucial for maintaining oxygenation and ventilation in individuals who have difficulty breathing on their own. Choice A is incorrect because feeding tubes are used for feeding, not for maintaining airways. Choice C is incorrect as checking vital signs does not require an artificial airway. Choice D is incorrect as preparing for a medical test does not involve the use of an artificial airway.
