Nursing Elites

1. The nurse is aware that norepinephrine is secreted by which endocrine gland?

• A. The pancreas
• B. The adrenal cortex
• C. The adrenal medulla
• D. The anterior pituitary gland

Correct answer: C

Rationale: The correct answer is C: The adrenal medulla. Norepinephrine is secreted by the adrenal medulla and is involved in the body's 'fight or flight' response. The pancreas (choice A) secretes insulin and glucagon, not norepinephrine. The adrenal cortex (choice B) secretes hormones like cortisol and aldosterone, but not norepinephrine. The anterior pituitary gland (choice D) secretes various hormones like growth hormone and thyroid-stimulating hormone, but not norepinephrine.

2. The nurse is teaching basic cardiopulmonary resuscitation (CPR) to individuals in the community. What is the correct order of basic CPR steps?

• A. Ensure the scene is safe, assess responsiveness, call for help, begin chest compressions, give two rescue breaths
• B. Give two rescue breaths
• C. Look, listen, and feel for breathing
• D. Begin chest compressions

Correct answer: A

Rationale: The correct order of basic CPR steps is as follows: first, ensure the scene is safe to approach, then assess the individual's responsiveness. After confirming the need for help, start chest compressions, then provide two rescue breaths. Option B, 'Give two rescue breaths,' is incorrect as chest compressions should be initiated before giving rescue breaths. Option C, 'Look, listen, and feel for breathing,' is also incorrect as immediate chest compressions are crucial in CPR. Option D, 'Begin chest compressions,' is partially correct but misses the crucial initial steps of ensuring scene safety and assessing responsiveness.

3. The client diagnosed with thalassemia, a hereditary anemia, is to receive a transfusion of packed RBCs. The cross-match reveals the presence of antibodies that cannot be cross-matched. Which precaution should the nurse implement when initiating the transfusion?

• A. Start the transfusion at 10-15 mL per hour for 15-30 minutes
• B. Re-crossmatch the blood until the antibodies are identified
• C. Have the client sign a permit to receive uncrossmatched blood
• D. Have the unlicensed nursing assistant stay with the client

Correct answer: A

Rationale: Starting the transfusion slowly at 10-15 mL per hour for 15-30 minutes is essential when the cross-match reveals the presence of antibodies that cannot be cross-matched. This precaution allows the nurse to monitor for any adverse reactions due to the antibodies. Re-crossmatching the blood until the antibodies are identified (choice B) may delay the transfusion process and put the client at risk. Having the client sign a permit to receive uncrossmatched blood (choice C) is not a standard practice and does not address the immediate need for precautions during transfusion. Having the unlicensed nursing assistant stay with the client (choice D) is unrelated to the safe initiation of the transfusion and is not a precaution specific to managing antibodies in blood products.

4. Which vitamin deficiency is commonly associated with prolonged antibiotic use?

• A. Vitamin A
• B. Vitamin B6
• C. Vitamin C
• D. Vitamin K

Correct answer: D

Rationale: The correct answer is Vitamin K. Prolonged antibiotic use can disrupt the gut flora, which is responsible for synthesizing Vitamin K. This disruption can lead to a Vitamin K deficiency and an increased risk of bleeding. Vitamin A, B6, and C deficiencies are not typically associated with prolonged antibiotic use.

5. The nurse is caring for a client on strict bed rest. Which intervention is the priority when caring for this client?

• A. Encourage the client to drink liquids
• B. Perform active range of motion exercises
• C. Elevate the head of the bed to 45 degrees
• D. Provide a high-fiber diet to the client

Correct answer: B

Rationale: Performing active range of motion exercises is the priority intervention for a client on strict bed rest. These exercises help prevent complications such as thromboembolism and muscle atrophy by promoting circulation and maintaining muscle strength. Encouraging liquids, elevating the head of the bed, and providing a high-fiber diet are important interventions but not the priority when compared to preventing serious complications associated with immobility.
