Nursing Elites

1. A nurse is caring for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?

• A. Glomerular filtration rate of 14 mL/min
• B. BUN 16 mg/dL
• C. Serum magnesium 1.8 mg/dL
• D. Serum phosphorus 4.0 mg/dL

Correct answer: A

Rationale: A glomerular filtration rate (GFR) of 14 mL/min is significantly low, indicating poor kidney function and the need for hemodialysis to remove waste products effectively. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and electrolyte balance but are not direct indicators for the initiation of hemodialysis. BUN (blood urea nitrogen) reflects the kidney's ability to filter waste products, serum magnesium levels are important for muscle and nerve function, and serum phosphorus levels are vital for bone health.

2. What is the priority nursing intervention for a patient with a stage 3 pressure ulcer?

• A. Apply hydrocolloid dressing
• B. Provide wound debridement
• C. Change the dressing daily
• D. Elevate the affected area

Correct answer: A

Rationale: The correct answer is to apply a hydrocolloid dressing. Stage 3 pressure ulcers are characterized by full-thickness skin loss involving damage to or necrosis of subcutaneous tissue, which requires a moist environment for healing. Hydrocolloid dressings help maintain a moist wound environment, promote healing, and provide protection. Providing wound debridement may be necessary but is not the priority intervention at this stage. Changing the dressing daily is important for wound care but not the priority over creating an optimal healing environment. Elevating the affected area can help with circulation and reduce swelling, but it is not the priority intervention for a stage 3 pressure ulcer.

3. A client with chronic kidney disease is being taught about dietary modifications by a nurse. Which of the following foods should the nurse instruct the client to avoid?

• A. Grilled chicken.
• B. Fresh fruit.
• C. White bread.
• D. Cheddar cheese.

Correct answer: D

Rationale: Cheddar cheese is high in phosphorus, which should be avoided by clients with chronic kidney disease. Fresh fruit is generally a healthy choice unless the client needs to limit potassium intake. Grilled chicken is a good protein source for clients with chronic kidney disease. White bread is low in phosphorus and can be included in the diet of clients with kidney disease unless they need to watch their carbohydrate intake.

4. A nurse is reviewing the medical record of a client who is at 30 weeks of gestation and has preeclampsia. Which of the following findings should the nurse report to the provider?

• A. Blood pressure 140/90 mm Hg
• B. 1+ pitting edema in the lower extremities
• C. Weight gain of 2.3 kg (5 lb) in 1 week
• D. Mild headache

Correct answer: C

Rationale: A weight gain of 2.3 kg (5 lb) in 1 week can indicate worsening preeclampsia due to fluid retention, which can lead to serious complications. This finding should be reported promptly to the provider for further assessment and intervention. Blood pressure of 140/90 mm Hg is high but may not be an immediate concern for a client with preeclampsia at 30 weeks. 1+ pitting edema in the lower extremities is common in pregnancy, especially in the third trimester, and may not be a significant finding in isolation. A mild headache can be a common symptom in pregnancy and may not be indicative of worsening preeclampsia unless accompanied by other concerning signs.

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

• A. Serum potassium
• B. Platelets
• C. aPTT
• D. INR

Correct answer: C

Rationale: The correct answer is C: aPTT. Monitoring the activated partial thromboplastin time (aPTT) is crucial when a client is receiving heparin therapy. The aPTT reflects the clotting time and helps assess the effectiveness of heparin in preventing clot formation. Keeping the aPTT within the therapeutic range ensures that the medication is working optimally. Choices A, B, and D are incorrect because serum potassium, platelets, and INR are not direct indicators of heparin's effectiveness or therapeutic range.
