1. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?

• A. hemoglobin
• B. transferrin
• C. myoglobin
• D. hepcidin

Correct answer: A

Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.

2. A nurse is assessing the nutritional status of an infant who is 6 months old. The infant weighed 2.7 kg at birth. Which of the following indicates to the nurse that the infant is within the expected range?

• A. 5.5 kg
• B. 6.4 kg
• C. 4.5 kg
• D. 3.6 kg

Correct answer: B

Rationale: The correct answer is B, 6.4 kg. An infant's weight should approximately double by 6 months. In this case, starting from a birth weight of 2.7 kg, a weight of 6.4 kg at 6 months indicates normal growth. Choice A (5.5 kg) is below the expected range for a 6-month-old infant. Choices C (4.5 kg) and D (3.6 kg) are also below the expected weight gain, indicating inadequate growth.
