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. Which is the best description of a full-liquid diet?

• A. Most suitable for individuals with an ileostomy
• B. Suitable for individuals with lactose intolerance
• C. Contains low saturated fat and high fiber
• D. Provides adequate nutrients and is easily digested

Correct answer: D

Rationale: The correct answer is D because a full-liquid diet is designed to provide adequate nutrients while being easily digested. Choices A and B are incorrect because a full-liquid diet is not specifically tailored for individuals with an ileostomy or lactose intolerance. Choice C is also incorrect as it describes characteristics that are not defining features of a full-liquid diet.

3. What activities best describe the work of the placenta during pregnancy?

• A. surrounding and cushioning the fetus
• B. combining maternal and fetal blood stores to exchange nutrients
• C. producing hormones that maintain the pregnancy
• D. absorbing vitamins and minerals that can be transferred to the fetus

Correct answer: C

Rationale: The placenta plays a crucial role in producing hormones that are necessary for maintaining pregnancy, supporting fetal development, and preparing the mother's body for childbirth. Choices A, B, and D are incorrect because the placenta's primary function is not to surround and cushion the fetus, combine blood stores for nutrient exchange, or absorb vitamins and minerals. While the placenta does facilitate the exchange of nutrients and oxygen between the mother and fetus, its hormone production is the most critical function during pregnancy.

4. A patient tells the nurse “I am depressed to talk to you, leave me alone” Which of the following response by the nurse is most therapeutic?

• A. I’ll be back in an hour
• B. Why are you so depressed?
• C. I’ll seat with you for a moment
• D. Call me when you feel like talking to me

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

5. What is a major goal for home care nurses?

• A. Restoring maximum health function.
• B. Promoting the health of populations.
• C. Minimizing the progress of disease.
• D. Maintaining the health of populations.

Correct answer: A

Rationale: A major goal for home care nurses is restoring maximum health function. This involves helping patients achieve their highest level of health and independence, focusing on individualized care plans tailored to each patient's needs. Choice B, promoting the health of populations, is more aligned with public health nursing rather than home care nursing. Choice C, minimizing the progress of disease, is important but not as comprehensive as restoring maximum health function. Choice D, maintaining the health of populations, is more about preventive care at a population level rather than the individualized care provided by home care nurses.
