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. Mang Carlos has a standing DNR order. He then suddenly stopped breathing and you are at his bedside. You would:

• A. Give extraordinary measures to save Mang Carlos
• B. Stay with Mang Carlos and Do nothing
• C. Call the physician
• D. Activate Code Blue

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.

3. Which set of guidelines is intended to assess nutrient adequacy or plan intake of a population group, not individuals?

• A. RDA
• B. EAR
• C. DRA
• D. UL

Correct answer: B

Rationale: The Estimated Average Requirement (EAR) is the correct choice because it is specifically designed to assess the nutrient adequacy of population groups, not individuals. The Recommended Dietary Allowance (RDA) (choice A) is the average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%-98%) healthy individuals in a particular life stage and gender group. The Dietary Reference Intake (DRI) (choice C) includes the EAR, RDA, Adequate Intake (AI), and UL, making it a broader set of nutrient reference values. The Tolerable Upper Intake Level (UL) (choice D) is the highest average daily nutrient intake level that is likely to pose no risk of adverse health effects to almost all individuals in the general population.

4. A nurse is planning care for a client who reports increasing difficulty swallowing food. Which of the following interventions should the nurse plan to take?

• A. Turn on the client’s television during meals.
• B. Place the client into a semi-reclining position for meals.
• C. Encourage the client to rest prior to mealtimes.
• D. Encourage the client to use a straw when drinking liquids.

Correct answer: C

Rationale: The correct answer is to encourage the client to rest prior to mealtimes. This intervention can help reduce fatigue and improve the ability to swallow. Turning on the client’s television during meals (choice A) may distract the client but does not directly address the swallowing issue. Placing the client into a semi-reclining position for meals (choice B) can help with swallowing difficulties, but resting before meals is more beneficial. Encouraging the client to use a straw when drinking liquids (choice D) is not the priority intervention for swallowing difficulties in this scenario.

5. In any event of an adverse hemolytic reaction during blood transfusion, Nursing intervention should focus on:

• A. Slow the infusion, Call the physician and assess the patient
• B. Stop the infusion, Assess the client, Send the remaining blood to the laboratory and call the physician
• C. Stop the infusion, Call the physician and assess the client
• D. Slow the confusion and keep a patent IV line open for administration of medication

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.
