Which of the following best describes what hormones and hemoglobin are made with?

Lipids

Glucose

Proteins

Carbohydrates

Answer and Explanation

The Correct Answer is C

A. Lipids: Some hormones (e.g., steroid hormones like estrogen and testosterone) are lipid-based, but not all. Hemoglobin is a protein, not a lipid.

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 A

Explanation

A. Low oxygen level: Cyanosis (bluish discoloration) and pallor (pale skin) suggest inadequate oxygenation of the blood, which can be due to respiratory or circulatory issues.

B. Liver disease: Liver disease is more commonly associated with jaundice (yellow discoloration) rather than cyanosis or pallor.

C. Skin cancer: Skin cancer often presents as abnormal moles, sores, or lesions rather than generalized cyanosis or pallor.

D. High blood sugar: High blood sugar (hyperglycemia) does not directly cause cyanosis or pallor; it may lead to dry skin and poor wound healing.

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.
