Lack of sleep can cause

Correct Answer: D

Rationale: The correct answer is D: Increased irritability. Lack of sleep disrupts mood regulation and can lead to increased irritability due to heightened emotional reactivity and decreased tolerance for stressors. This is supported by research showing that sleep deprivation negatively impacts emotional regulation. The other choices are incorrect because lack of sleep actually causes decreased mental function, slower reaction time, and weakened immune system function.

Correct Answer: A

Rationale: The correct answer is A: Muscle aches. Fever often causes muscle aches due to the body's inflammatory response to infection. This is a common symptom as elevated body temperature can lead to muscle discomfort. Sleepiness (B) is a possible symptom but not as specific to fever. Slow movements (C) are not directly caused by fever. Nausea (D) can be a symptom of fever, but muscle aches are more commonly associated with it.

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: The correct answer is A: Skin that appears tight, smooth, and shiny. Fluid overload leads to increased fluid accumulation in the body, resulting in edema. This excess fluid can cause the skin to appear tight, smooth, and shiny due to swelling. B: Weight loss is not a symptom of fluid overload, as it is typically associated with fluid deficit or dehydration. C: Increased urine output is a symptom of fluid excess, not fluid overload. In fluid overload, the body struggles to eliminate the excess fluid, leading to edema and decreased urine output. D: Decreased heart rate is not a direct symptom of fluid overload. In fact, fluid overload can strain the heart, leading to an increased heart rate as the heart works harder to pump the excess fluid.

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.
