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

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. During the Emergent phase of a burn, the most fatal electrolyte imbalance in a burned client is:

Correct answer: A

Rationale: During the Emergent phase of burns, the most fatal electrolyte imbalance is Hypokalemia. This is due to the shift of potassium from the intracellular space to the extracellular space, leading to low potassium levels in the blood. Choices B, C, and D are incorrect because Hyperkalemia, Hypernatremia, and Hyponatremia are not typically associated with the Emergent phase of burns and do not pose the same level of risk as Hypokalemia in this context.

3. The nurse is assessing a client with a new diagnosis of Listeria food poisoning. What action should the nurse take first?

Correct answer: D

Rationale: The correct first action for the nurse to take when assessing a client with a new diagnosis of Listeria food poisoning is to inquire if the client has consumed any unpasteurized products. This is crucial because Listeria contamination is often associated with unpasteurized dairy products and undercooked meats. Educating the client on safe food practices (Choice A) is important but not the priority at this initial assessment stage. Starting a traceback to identify the source of the outbreak (Choice B) and reporting the case to the county board of health (Choice C) are necessary actions but should come after gathering information directly from the client regarding potential exposure to high-risk foods.

4. Water loss can occur from each, except one. Which is the exception?

Correct answer: D

Rationale: The correct answer is D, Perspiration. Water loss can occur through respiration inflammation, strenuous exercise, and diarrhea. Perspiration, also known as sweating, is a mechanism by which the body regulates temperature and eliminates some waste products, but it is not a cause of water loss. The body loses water through sweating, but this loss is mainly for cooling purposes, and it is not a primary mechanism for water loss like respiration, exercise, or diarrhea.

5. Which nutrient is most important for wound healing in a patient post-surgery?

Correct answer: B

Rationale: Protein is essential for tissue repair and wound healing.
