Nursing Elites

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. In kidney disease, which mineral should a patient limit intake of?

• A. Calcium
• B. Magnesium
• C. Phosphorus
• D. Potassium

Correct answer: C

Rationale: In kidney disease, patients are advised to limit the intake of phosphorus. High levels of phosphorus can be problematic as the kidneys may not be able to effectively filter it out, leading to bone health issues. Calcium (Choice A) is important for bone health, but its restriction is not typically necessary in kidney disease. Magnesium (Choice B) and potassium (Choice D) restrictions may be required in certain cases of kidney disease, but phosphorus is the mineral most commonly limited due to its impact on bone health.

3. List 2 Dispensable amino acids

• A. Alanine
• B. Serine
• C. Glycine
• D. Proline

Correct answer: A

Rationale: Dispensable amino acids, such as alanine and serine, can be synthesized by the body and are not required to be obtained from the diet.

4. A client with cirrhosis and ascites is being cared for by a nurse. Which of the following interventions should the nurse include in the plan of care?

• A. Decrease the client's fluid intake.
• B. Increase the client's saturated fat intake.
• C. Increase the client's sodium intake.
• D. Decrease the client's carbohydrate intake.

Correct answer: D

Rationale: In a client with cirrhosis and ascites, decreasing carbohydrate intake is essential as it helps reduce the production of ascitic fluid. Excess carbohydrates can lead to fluid retention. Choices A, B, and C are incorrect. Decreasing fluid intake can worsen dehydration, increasing saturated fat intake is not recommended due to its impact on liver health, and increasing sodium intake can worsen fluid retention and exacerbate ascites in these clients.

5. A nurse is providing preventative information to a group of parents with toddlers about choking. Which food item should the nurse recommend for this age group?

• A. Banana slices
• B. Popcorn
• C. Hot dogs
• D. Carrot sticks

Correct answer: A

Rationale: Banana slices are the most suitable food option for toddlers to prevent choking. Toddlers are at a higher risk of choking due to their small airways and developing chewing abilities. Banana slices are soft, easy to chew, and less likely to cause choking compared to other options. Popcorn and hot dogs are common choking hazards for young children due to their shape and texture. While carrot sticks may be a healthy choice, they can also pose a choking risk due to their hardness and shape. Therefore, recommending banana slices to parents of toddlers is the safest choice to prevent choking incidents, making choice 'A' the correct answer. Choices 'B', 'C', and 'D' are incorrect because they can potentially cause choking in toddlers.
