Nursing Elites

1. A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?

• A. Administer IV calcium gluconate.
• B. Administer sodium polystyrene sulfonate (Kayexalate).
• C. Administer insulin with dextrose.
• D. Restrict potassium intake in the client's diet.

Correct answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

2. A client is receiving continuous intravenous heparin for a deep vein thrombosis. Which laboratory result should the nurse monitor to ensure therapeutic heparin levels?

• A. International normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Hemoglobin
• D. Platelet count

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is the most accurate measure of heparin's therapeutic effect. Heparin increases the time it takes for blood to clot, and the aPTT helps determine whether the dose is within the desired range for anticoagulation therapy. Monitoring the INR, hemoglobin, or platelet count is not specific to assessing therapeutic heparin levels and may not reflect the anticoagulant effect of heparin.

3. A client presents to the emergency department with a severe exacerbation of asthma. The nurse notes that the client is using accessory muscles to breathe and has an oxygen saturation of 86%. Which intervention should the nurse implement first?

• A. Place the client in a high-Fowler's position
• B. Obtain a peak flow reading
• C. Administer a bronchodilator
• D. Administer oxygen therapy

Correct answer: D

Rationale: The first priority in an acute asthma exacerbation is to administer oxygen to improve the client's oxygen saturation. In this scenario, the client has a low oxygen saturation level of 86%, indicating hypoxemia, which can be life-threatening. Administering oxygen therapy will help improve oxygenation and support vital organ function. Once the oxygen levels are stabilized, further interventions such as bronchodilators can be implemented. Placing the client in a high-Fowler's position may also be beneficial, but ensuring adequate oxygenation takes precedence in this critical situation. Obtaining a peak flow reading is important for asthma management but is not the first intervention needed in a client with severe hypoxemia.

4. A 4-year-old has been hospitalized for 24 hours with skeletal traction for treatment of a fracture of the right femur. The nurse finds that the child is now crying and the right foot is pale with the absence of a pulse. What should the nurse do first?

• A. Notify the healthcare provider
• B. Readjust the traction
• C. Administer the ordered PRN medication
• D. Reassess the foot in fifteen minutes

Correct answer: A

Rationale: A pale foot with no pulse suggests a compromised blood supply, indicating a potential vascular emergency. The nurse's immediate priority is to notify the healthcare provider to address the situation promptly. Readjusting the traction, administering PRN medication, or waiting to reassess the foot later could lead to serious complications due to the compromised blood supply, making choices B, C, and D incorrect in this critical situation.

5. While changing a client's chest tube dressing, the nurse notes a cracking sensation when gentle pressure is applied to the skin at the insertion site. What is the best action for the nurse to take?

• A. Apply a pressure dressing around the chest tube site.
• B. Administer an oral antihistamine.
• C. Assess for allergies to topical cleaning agents.
• D. Measure the area of swelling and crackling.

Correct answer: D

Rationale: When a nurse observes crepitus around a chest tube site, it could indicate subcutaneous emphysema, a potentially serious condition where air gets trapped under the skin. Measuring the area of swelling and crackling is important as it helps monitor the progression of subcutaneous emphysema. Applying a pressure dressing (choice A) might not address the underlying cause and could potentially worsen the condition. Administering an oral antihistamine (choice B) is not indicated for crepitus at a chest tube site. Assessing for allergies to topical cleaning agents (choice C) is important but not the immediate priority when crepitus is observed.
