Nursing Elites

1. A healthcare provider is reviewing laboratory results for a client who is receiving heparin therapy. Which of the following results indicates that the medication is effective?

• A. Platelets 250,000/mm³
• B. aPTT 60 seconds
• C. Hemoglobin 15 g/dL
• D. INR 1.5

Correct answer: B

Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.

2. A client is at risk for developing deep vein thrombosis (DVT). Which of the following actions should the nurse take?

• A. Encourage the client to remain on bed rest.
• B. Massage the client's legs every 4 hours.
• C. Apply sequential compression devices to the client's legs.
• D. Administer anticoagulants as prescribed.

Correct answer: C

Rationale: The correct action the nurse should take for a client at risk for developing DVT is to apply sequential compression devices to the client's legs. This intervention helps prevent venous stasis by promoting circulation and reducing the risk of DVT. Encouraging the client to remain on bed rest (Choice A) can actually increase the risk of DVT due to immobility. Massaging the client's legs every 4 hours (Choice B) can dislodge blood clots and is contraindicated in DVT prevention. While administering anticoagulants as prescribed (Choice D) is a treatment for DVT, it is not a preventive measure for a client at risk.

3. A nurse is providing teaching to a client who is experiencing preterm contractions and dehydration. Which statement should the nurse make?

• A. Dehydration is treated with calcium supplements.
• B. Dehydration can increase the risk of preterm labor.
• C. Dehydration is caused by decreased hemoglobin and hematocrit.
• D. Dehydration causes gastroesophageal reflux.

Correct answer: B

Rationale: The correct statement is B: 'Dehydration can increase the risk of preterm labor.' Dehydration can lead to increased uterine irritability, potentially causing preterm contractions and labor. Choice A is incorrect as dehydration is not treated with calcium supplements but rather with fluids. Choice C is incorrect as dehydration is not caused by decreased hemoglobin and hematocrit levels but rather by a lack of fluids. Choice D is incorrect as dehydration does not directly cause gastroesophageal reflux.

4. A nurse is caring for a client who has Crohn's disease. Which of the following findings should the nurse expect?

• A. Weight gain.
• B. Bloody stools.
• C. Urinary retention.
• D. Abdominal distention.

Correct answer: B

Rationale: The correct answer is B: Bloody stools. Bloody stools are a common symptom of Crohn's disease, characterized by inflammation of the digestive tract. Weight gain (choice A) is less likely due to malabsorption issues associated with Crohn's disease. Urinary retention (choice C) is not directly related to Crohn's disease. Abdominal distention (choice D) may occur in Crohn's disease but is not as specific a finding as bloody stools.

5. 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.
