Nursing Elites

1. 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.

2. A nurse in a pediatric clinic is teaching a newly hired nurse about the varicella roster. Which of the following information should the nurse include?

• A. Children who have varicella are contagious until vesicles are crusted
• B. Children who have varicella should receive the herpes zoster vaccination
• C. Children who have varicella should be placed in droplet precautions
• D. Children who have varicella are contagious 4 days before the first vesicle eruption

Correct answer: A

Rationale: The correct answer is A. Children with varicella are contagious until the vesicles crust over, which is important for preventing transmission. Choice B is incorrect as varicella and herpes zoster are caused by different viruses, so the varicella vaccine is given to prevent varicella, not herpes zoster. Choice C is incorrect because varicella is primarily spread through respiratory secretions, so airborne precautions are recommended, not droplet precautions. Choice D is incorrect as children with varicella are contagious even before the first vesicle eruption, not just 4 days before.

3. A client is being assessed in the PACU. Which of the following findings indicates decreased cardiac output?

• A. Shivering
• B. Oliguria
• C. Bradypnea
• D. Constricted pupils

Correct answer: B

Rationale: Oliguria is a sign of decreased cardiac output. Decreased cardiac output can lead to poor renal perfusion, resulting in decreased urine output (oliguria). This requires immediate intervention to improve cardiac function and perfusion. Shivering (Choice A) is a response to cold stress and does not directly indicate decreased cardiac output. Bradypnea (Choice C) refers to abnormally slow breathing rate and is more indicative of respiratory issues rather than decreased cardiac output. Constricted pupils (Choice D) are associated with the parasympathetic nervous system response and not directly related to cardiac output.

4. A nurse is reviewing the medical record of a client who has chronic kidney disease. The client's potassium level is 6.5 mEq/L. Which of the following actions should the nurse take?

• A. Administer sodium bicarbonate
• B. Administer sodium polystyrene sulfonate
• C. Administer calcium gluconate
• D. Administer calcium carbonate

Correct answer: B

Rationale: The correct answer is B: Administer sodium polystyrene sulfonate. Sodium polystyrene sulfonate is used to treat hyperkalemia by promoting the excretion of potassium. Choice A, administering sodium bicarbonate, is incorrect as it is not used to treat hyperkalemia. Choice C, administering calcium gluconate, is incorrect as it is used to treat hypocalcemia, not hyperkalemia. Choice D, administering calcium carbonate, is incorrect as it is used to treat conditions like osteoporosis and indigestion, not hyperkalemia.

5. A nurse is planning care for a client who has pneumonia. Which of the following interventions should the nurse include to promote airway clearance?

• A. Encourage the client to increase fluid intake.
• B. Suction the client every 2 hours.
• C. Perform chest physiotherapy every 8 hours.
• D. Administer oxygen via nasal cannula.

Correct answer: A

Rationale: Encouraging the client to increase fluid intake is essential to promote airway clearance in pneumonia. Adequate hydration helps to thin respiratory secretions, making them easier to expectorate. Suctioning every 2 hours may be too frequent and can lead to airway trauma and irritation. Chest physiotherapy is not typically indicated for pneumonia unless there are specific complications. Administering oxygen via nasal cannula may be necessary to maintain oxygen saturation but does not directly promote airway clearance.
