Nursing Elites

1. In the newborn nursery, the nurse admits a baby from labor and delivery who is suspected of having a congenital heart disease. Which finding helps to confirm this diagnosis?

• A. Pink lips and tongue with cyanotic hands and feet
• B. Respiration rate of 40 and heart rate of 144
• C. Centralized cyanosis and tachycardia when crying
• D. Desquamation from areas of cracked, parchment-like skin

Correct answer: C

Rationale: Centralized cyanosis and tachycardia are classic signs of congenital heart disease. Choice A is incorrect because cyanosis in the hands and feet is not specific to congenital heart disease. Choice B is incorrect as the vital signs provided are not specific indicators of congenital heart disease. Choice D is unrelated to the typical signs of congenital heart disease.

2. When evaluating the preoperative teaching of a client scheduled for arthroscopic anterior cruciate ligament repair, which statement by the client indicates that the teaching was effective?

• A. I will use crutches to keep my weight off my knee
• B. I will stay home until a wheelchair is delivered
• C. I can use the trapeze bar and side rails on the bed to help me turn regularly
• D. I can put my full weight on my foot starting the day after surgery

Correct answer: A

Rationale: The correct answer is A. Using crutches indicates an understanding of weight-bearing restrictions post-surgery. Choice B is incorrect because waiting for a wheelchair is not related to postoperative mobility instructions. Choice C is incorrect as turning in bed using the trapeze bar and side rails does not address weight-bearing restrictions. Choice D is incorrect because putting full weight on the foot immediately after surgery contradicts the need to keep weight off the knee.

3. A nurse is assessing the learning needs of a client who is diagnosed with Addison's disease. Which statement indicates that the client needs further teaching?

• A. I should take my medications daily to replace necessary hormones
• B. I need to eat a diet high in protein and carbohydrates
• C. I should avoid drinking fluids with caffeine
• D. I should notify my healthcare provider if I start feeling dizzy

Correct answer: B

Rationale: The correct answer is B. A diet high in protein and carbohydrates is not specifically required for Addison's disease. The focus should be on maintaining a balanced diet that is rich in fruits, vegetables, whole grains, and adequate protein sources. Choice A is correct as adherence to medication therapy is crucial in managing Addison's disease. Choice C is correct as caffeine can exacerbate symptoms of Addison's disease. Choice D is correct as dizziness can be a sign of adrenal crisis in Addison's disease, and prompt notification of healthcare providers is essential.

4. The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?

• A. Blood glucose of 140 mg/dL
• B. White blood cell count of 8000/mm³
• C. Serum potassium of 3.8 mEq/L
• D. Serum calcium of 7.8 mg/dL

Correct answer: D

Rationale: The correct answer is D. A serum calcium level of 7.8 mg/dL requires immediate intervention due to the risk of hypocalcemia. Hypocalcemia can lead to serious complications such as tetany, seizures, and cardiac arrhythmias. The other laboratory findings are within normal limits or slightly elevated, which do not pose an immediate threat to the client's health in this scenario.

5. The nurse is caring for a client who is receiving a continuous intravenous infusion of heparin. Which laboratory value should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Partial thromboplastin time (PTT)
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.
