What is the main function of proteins in the body?

Correct Answer: A

Rationale: The main function of proteins in the body is to provide structural components like muscles, skin, and bones. Proteins are essential for growth, repair, and maintenance of body tissues. While proteins play a role in various physiological functions, their primary function is not to assist in the absorption of vitamins (Choice B), help with the transport of nutrients in the blood (Choice C), or maintain fluid balance (Choice D).

Correct Answer: B

Rationale: The correct answer is to assess bowel sounds and pain location. In a child with suspected appendicitis, focusing on bowel sounds and pain location, particularly in the lower right quadrant, is crucial. This assessment helps to identify symptoms commonly associated with appendicitis. Assessing the level of consciousness (Choice A) is important in other conditions such as head injuries or neurological issues. Skin color and temperature (Choice C) are more indicative of circulatory or skin-related problems. Heart rate and blood pressure (Choice D) are vital signs that are essential to assess in various conditions but are not specific to suspected appendicitis.

Correct Answer: B

Rationale: Dry mouth and lips are common signs of dehydration in infants. When an infant is dehydrated, the body conserves water, resulting in less urine production and concentrated urine. This leads to decreased frequency of urination rather than frequent urination, making choice A incorrect. Choice C, increased appetite, is not typically associated with dehydration in infants but rather with normal growth and development. Normal skin turgor, as mentioned in choice D, is a sign of hydration and not dehydration, making it an incorrect choice. Therefore, the correct answer is B, dry mouth and lips, which indicate a need for fluid replacement.

Correct Answer: B

Rationale: Increasing fluid intake and rest is a primary intervention for a child with a suspected respiratory infection because it helps support the body's recovery and maintains hydration levels. Antiviral medications (Choice A) are only used for specific viral infections and are not routinely recommended for suspected respiratory infections. Restricting physical activity (Choice C) may be necessary in certain cases to prevent overexertion, but it is not a primary intervention. Providing high-dose vitamin supplements (Choice D) may support the immune system in general but is not a primary intervention for a suspected respiratory infection.

Correct Answer: A

Rationale: Administering a bronchodilator is an essential part of caring for a child with asthma during an acute episode because it helps to open airways and relieve acute asthma symptoms effectively. Providing high doses of steroids (Choice B) is typically done in severe cases or when other treatments fail. Increasing fluid intake (Choice C) can be beneficial to prevent dehydration, but it is not the primary intervention during an acute asthma episode. Restricting all physical activity (Choice D) is not recommended as some physical activity may help improve lung function and overall well-being.
