A nurse is instructing a group of clients about nutrition. The nurse should include that which of the following is a trigger for the formation of vitamin D in the body?

Exposure to sunlight

Vitamin A depletion

Weight-bearing exercise

Calcium

Answer and Explanation

The Correct Answer is A

A.   Vitamin D is synthesized in the skin in response to exposure to ultraviolet B (UVB) rays from sunlight. When the skin is exposed to sunlight, specifically UVB rays, a chemical reaction occurs that converts 7- dehydrocholesterol (a substance found in the skin) into vitamin D3 (cholecalciferol). This form of vitamin D is then converted into its active form in the liver and kidneys.
B.   This is not related to the formation of vitamin D. While vitamin A is important for overall health and vision, it does not play a role in the synthesis of vitamin D. Vitamin D formation is independent of vitamin A levels in the body.
C.   This is not a direct trigger for vitamin D formation. While weight-bearing exercise is important for bone health and can improve overall musculoskeletal function, it does not influence the production of vitamin D in the body. The synthesis of vitamin D is primarily influenced by exposure to sunlight.
D.   Calcium does not trigger vitamin D formation. While calcium and vitamin D are closely related, with vitamin D being essential for optimal calcium absorption, the presence of calcium does not affect the synthesis of vitamin D. Instead, calcium levels influence how much vitamin D is needed to ensure proper calcium absorption.

Correct Answer is C

Explanation

A. This device is used to prevent hip rotation and adduction. It is placed along the lateral side of the client's hips to keep the hips in a neutral position, preventing external rotation and adduction. It does not specifically address plantar flexion contractures of the feet.
B. This device is used primarily to reduce pressure and prevent heel ulcers, not to prevent plantar flexion contractures. Sheepskin pads provide cushioning to prevent pressure sores, but they do not help in maintaining the proper position of the feet to prevent contractures.
C. This is the appropriate device for preventing plantar flexion contractures. A footboard is placed at the end of the bed to keep the feet in a dorsiflexed position, preventing them from curling downward. It helps maintain the feet in a neutral or slightly dorsiflexed position, thus preventing plantar flexion contractures.
D. This device is used to maintain the hips in an abducted position, typically following hip surgery. It prevents the legs from coming together and helps with hip alignment but does not address the issue of plantar flexion contractures.

A. Scrambled eggs B. Cottage cheese C. Piece of wheat toast D. Sliced banana

Correct Answer is C

Explanation

A. Scrambled eggs are soft, moist, and easy to chew and swallow, making them suitable for a mechanically altered diet.
B. Cottage cheese is soft and moist, which makes it easy to swallow and suitable for clients on a mechanically altered diet.
C. A piece of wheat toast is hard and dry, and it requires significant chewing. It is not suitable for a mechanically altered diet because it can pose a choking hazard and is difficult to swallow for individuals with chewing or swallowing difficulties.
D. Sliced banana is soft and moist, which makes it easy to chew and swallow. It is appropriate for a mechanically altered diet.
