A warning sign of dehydration is

Correct Answer: B

Rationale: Correct Answer: B Rationale: 1. Dehydration can lead to difficulty swallowing liquids due to decreased saliva production. 2. This symptom indicates a potential lack of hydration in the body. 3. Residents may avoid drinking due to swallowing issues, exacerbating dehydration. 4. Increased thirst and drinking at meals (choices A and C) are common responses to dehydration but do not necessarily indicate dehydration itself. 5. Increased urinary output (choice D) can be a sign of good hydration or other health conditions, not necessarily dehydration.

Correct Answer: B

Rationale: The correct answer is B: Prevents the loss of too much water. The integumentary system consists of the skin, hair, nails, and glands, which act as a barrier to prevent dehydration by retaining body fluids. It helps regulate body temperature, protects against pathogens, and provides sensory information. Choices A, C, and D do not directly relate to the primary function of the integumentary system, making them incorrect. A regulates hormones (endocrine system), C relates to the muscular system, and D involves the reproductive system.

Correct Answer: C

Rationale: The correct answer is C: Peripheral arterial disease (PAD). PAD is the most common type of PVD characterized by atherosclerosis in the arteries supplying the extremities. This leads to reduced blood flow, causing symptoms like leg pain, cramping, and impaired wound healing. Phlebitis (A) is inflammation of veins, not arteries. Myocardial infarction (MI) (B) and Coronary artery disease (CAD) (D) involve the heart's blood vessels, not peripheral arteries. Therefore, based on the symptoms and location of atherosclerosis, PAD is the most likely diagnosis.

Correct Answer: A

Rationale: The correct answer is A: Dry. Before applying a prosthesis, the area must be dry to ensure proper adhesion. Moisture can prevent the prosthesis from adhering effectively, leading to potential issues such as slippage or skin irritation. Options B, C, and D are incorrect because a damp, cold, or warm area can all contribute to poor adhesion and discomfort for the patient. Ensuring the area is dry is crucial for the successful application and longevity of the prosthesis.

Correct Answer: B

Rationale: The correct answer is B because using touch and smiles can help communicate non-verbally with a resident who has lost verbal skills due to Alzheimer's disease. Touch and smiles can convey empathy, comfort, and support, making the resident feel understood and cared for. This approach maintains a connection with the resident and can alleviate feelings of frustration or isolation. A: Assuming the resident cannot understand is incorrect as it may lead to neglecting their emotional needs. C: Asking the resident questions may cause confusion or frustration if they cannot respond verbally. D: Not involving the resident in activities can worsen feelings of isolation and decrease their quality of life.
