How often should residents in wheelchairs be repositioned?

Correct Answer: C

Rationale: The correct answer is C: At least every two hours. Repositioning residents in wheelchairs every two hours helps prevent pressure ulcers and discomfort. Repositioning every 15 minutes (A) may not be necessary unless prescribed by a healthcare provider for specific cases. Every hour (B) may be too frequent for some residents, leading to unnecessary disruptions. Repositioning every five minutes (D) is too frequent and can be impractical and disruptive. Regular repositioning promotes circulation and prevents skin breakdown without causing unnecessary discomfort.

Correct Answer: D

Rationale: The correct answer is D: Soy. Soy products are lactose-free and can be used as a substitute for dairy products in individuals who are lactose intolerant. Soy milk, tofu, and soy-based cheeses are good alternatives. Fiber (choice A) and protein (choice C) are not direct substitutes for dairy products. Salt (choice B) is not a suitable substitute for lactose intolerance. Soy is the best choice due to its lactose-free nature and ability to provide similar nutrients as dairy products.

Correct Answer: A

Rationale: The correct answer is A: Specific gravity test. This test measures the concentration of solutes in urine, indicating the urine density or concentration. Specific gravity test is used to assess the kidney's ability to concentrate urine. The other choices, pH test, glucose test, and occult blood test, do not directly measure urine density. pH test measures the acidity or alkalinity of urine, glucose test detects sugar levels, and occult blood test detects hidden blood in urine. These tests provide different information and are not specific to urine density.

Correct Answer: B

Rationale: The correct answer is B: Scabies. Scabies is a highly contagious skin infestation caused by a mite that burrows into the skin. It is primarily transmitted through direct person-to-person contact, such as skin-to-skin contact. Shingles (A) is caused by the varicella-zoster virus and is not transmitted through direct person-to-person contact. Skin cancer (C) is not contagious and is caused by genetic and environmental factors. Eczema (D) is a chronic skin condition that is not contagious and is influenced by genetics and environmental triggers.

Correct Answer: B

Rationale: The correct answer is B: Bronchiectasis. Bronchiectasis is a condition characterized by the permanent dilation of the bronchi due to chronic inflammation and damage to the airways. This leads to a build-up of mucus and recurrent infections. Bronchitis (choice A) is inflammation of the bronchial tubes but does not result in permanent dilation. Asthma (choice C) is a chronic respiratory condition characterized by airway inflammation and bronchoconstriction but does not involve permanent dilation. Pneumonia (choice D) is an infection of the lungs and does not cause permanent bronchial dilation.
