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 healthcare professional is reviewing the lab findings of a client who has Clostridium Difficile. Which of the following findings should indicate to the healthcare professional that the client is experiencing Fluid Volume Deficit?

• A. Hct 53%
• B. Potassium 3.5
• C. Sodium 145
• D. HbA1c 5

Correct answer: A

Rationale: An elevated hematocrit level (Hct 53%) indicates hemoconcentration, a sign of fluid volume deficit. Hct measures the percentage of red blood cells in the blood and increases when there is a decrease in plasma volume, as seen in fluid volume deficit. Choices B, C, and D do not directly relate to fluid volume status. Potassium and sodium levels are more indicative of electrolyte imbalances, while HbA1c reflects average blood sugar levels over the past 2-3 months and is not specific to fluid volume status.

3. Which is NOT a prudent recommendation for a menopausal patient?

• A. Supplement calcium and vitamin D slightly beyond upper intake level
• B. Encourage lean protein and regular exercise
• C. Avoid alcohol if xerostomia is present
• D. Consumption of 90 mg daily of isoflavones in soy products helps to increase bone mass

Correct answer: A

Rationale: Excessive supplementation of calcium and vitamin D beyond the upper intake level is not recommended unless under medical supervision, as it can cause adverse health effects.

4. In consideration of the steps in applying the bag technique, which side of the paper lining of the CHN bag is considered clean to make a non-contaminated work area?

• A. The lower lip
• B. The outer surface
• C. The upper tip
• D. The inside surface

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. Each of the following is a fat-soluble vitamin except for one. Which is the exception?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin K

Correct answer: B

Rationale: The correct answer is B, Vitamin C. Vitamin C is a water-soluble vitamin, not fat-soluble. Fat-soluble vitamins are Vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver, unlike water-soluble vitamins which are not stored and are eliminated in urine, making them less likely to reach toxic levels.
