_____ help(s) the body grow new tissue and enable(s) tissue repair.

Correct Answer: A

Rationale: Proteins are the correct answer because they are essential for tissue growth and repair. Proteins provide the building blocks (amino acids) necessary for cell regeneration and repair processes. Fats primarily serve as an energy source, carbohydrates are mainly for energy production, and while water is crucial for overall bodily functions, it does not directly facilitate tissue growth and repair like proteins do.

Correct Answer: A

Rationale: Correct Answer: A Rationale: Wiping from front to back prevents the spread of bacteria from the anal area to the vaginal area, reducing the risk of urinary tract infections. It is important to maintain proper hygiene to prevent infections in the perineal area. Summary of Incorrect Choices: B: Wiping from back to front can introduce bacteria from the anal area to the vaginal area, increasing the risk of infections. C: Wiping the anal area first can transfer bacteria to the vaginal area, leading to infections. D: Using the same area of the washcloth for each stroke can spread bacteria and increase the risk of cross-contamination.

Correct Answer: A

Rationale: The correct answer is A: First-degree (superficial) burn. This type of burn affects only the epidermis, causing redness and pain. The epidermis is the outer layer of the skin, so a burn that affects only this layer is classified as a first-degree burn. Choices B, C, and D are incorrect because they describe burns that penetrate deeper layers of the skin. Second-degree burns (B) involve the epidermis and part of the dermis, causing blisters and more severe pain. Third-degree burns (C) damage all layers of the skin and may result in numbness due to nerve damage. Scalds (D) refer to burns caused by hot liquids or steam, but the severity of the burn depends on the depth of tissue damage, not just the cause.

Correct Answer: D

Rationale: The correct answer is D because range of motion exercises help improve muscle tone, strength, and flexibility in patients with congestive heart failure. This can help prevent muscle wasting and improve overall physical function. Choice A is incorrect as high-sodium diet can worsen fluid retention and exacerbate heart failure symptoms. Choice B is incorrect as medications causing a decrease in urinary output can lead to fluid retention and worsen heart failure. Choice C is incorrect as forcing fluids can increase fluid overload in patients with heart failure, putting extra strain on the heart.

Correct Answer: C

Rationale: The correct answer is C: Elevate an extremity that is in a cast. Elevating the extremity helps reduce swelling and promote circulation. This is important for proper healing and preventing complications. Keeping the cast wet or damp (A) can lead to skin irritation and infection. Using a sharp object to remove items in the cast (B) can cause injury. Washing a cast with warm water and soap (D) can weaken the cast material and compromise its integrity.
