Lipids

Glucose

Proteins

Carbohydrates

Answer and Explanation

The Correct Answer is C

B. Glucose: Glucose is a carbohydrate used for energy, not for building hormones or hemoglobin.

C. Proteins: Hormones (such as insulin and growth hormone) and hemoglobin (which carries oxygen in red blood cells) are protein-based molecules essential for bodily functions.

D. Carbohydrates: Carbohydrates provide energy but do not contribute to the structure of proteins like hormones and hemoglobin.

Correct Answer is D

Explanation

A. Unsaturated fats (HDL): High-density lipoprotein (HDL) is considered "good cholesterol" because it helps remove LDL cholesterol from the blood, reducing the risk of heart disease.

B. Omega-3 fatty acids: Omega-3 fatty acids are healthy fats that reduce inflammation and lower the risk of heart disease by improving heart health.

C. Omega-6 fatty acids: While excessive omega-6 intake may contribute to inflammation, they are not the primary contributors to plaque buildup in blood vessels like saturated fats (LDL).

D. Saturated fats (LDL): Saturated fats increase low-density lipoprotein (LDL), also known as "bad cholesterol," which contributes to plaque buildup in arteries and increases the risk of heart disease.

A. Sterile sheets pull water out of the burn site B. The loss of skin causes the loss of large amount of body fluid C. He is thirsty D. He has not had anything to drink since the accident

Correct Answer is B

Explanation

A. Sterile sheets pull water out of the burn site: Sterile sheets help maintain a clean environment but do not significantly draw fluids from the wound.

B. The loss of skin causes the loss of large amounts of body fluid: Third-degree burns destroy the skin barrier, leading to severe fluid loss due to increased capillary permeability, which results in fluid shifts and hypovolemic shock.

C. He is thirsty: While burn patients may feel thirsty due to dehydration, IV fluids are given to restore lost fluids, not just to satisfy thirst.

D. He has not had anything to drink since the accident: Oral hydration is not sufficient in severe burn cases due to the large fluid loss and the need for rapid replacement through IV fluids.
