Nursing Elites

1. A client receiving heparin therapy experiences a drop in platelet count. What is the nurse's priority action?

• A. Continue to monitor the platelet count.
• B. Discontinue the heparin infusion.
• C. Administer platelet transfusion.
• D. Notify the healthcare provider immediately.

Correct answer: D

Rationale: The correct answer is D: Notify the healthcare provider immediately. A drop in platelet count during heparin therapy may indicate heparin-induced thrombocytopenia (HIT), a serious condition that increases the risk of clot formation. Immediate discontinuation of heparin is necessary to prevent further complications. Administering platelet transfusion without addressing the underlying cause can be harmful. Continuing to monitor the platelet count without taking immediate action can lead to delayed intervention. Notifying the healthcare provider promptly allows for assessment and initiation of alternative anticoagulation therapy to manage the client's condition effectively.

2. The healthcare provider prescribes an IV infusion of isoproterenol in D5W at 300 mcg/hour. How many ml/hour should the nurse set the pump to?

• A. 100 ml/hour
• B. 75 ml/hour
• C. 60 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct infusion rate, convert 300 mcg/hour to mg/hour (300 mcg = 0.3 mg). Since the IV solution is 1 mg in 250 ml, the rate is calculated as 0.3 mg/hour = 75 ml/hour. Therefore, the nurse should set the pump to 75 ml/hour. Choice A (100 ml/hour) is incorrect as it does not reflect the accurate calculation. Choice C (60 ml/hour) is incorrect as it is lower than the correct rate. Choice D (125 ml/hour) is incorrect as it is higher than the correct rate.

3. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

4. The nurse is providing teaching to a client with gastroesophageal reflux disease (GERD). Which instruction should the nurse include?

• A. Eat large meals to decrease acid production
• B. Avoid lying down immediately after eating
• C. Limit fluid intake with meals
• D. Drink carbonated beverages to aid digestion

Correct answer: B

Rationale: The correct instruction for a client with GERD is to avoid lying down immediately after eating. This helps prevent stomach acid from flowing back into the esophagus, which can worsen symptoms. Eating large meals can actually increase acid production and exacerbate GERD. Limiting fluid intake with meals may be beneficial for some individuals, but it is not a key instruction for managing GERD. Drinking carbonated beverages can trigger reflux symptoms and should be avoided by individuals with GERD.

5. A client who had a subtotal parathyroidectomy two days ago is now preparing for discharge. Which assessment finding requires immediate provider notification?

• A. Afebrile with a normal pulse.
• B. No bowel movement since surgery.
• C. No appetite for breakfast.
• D. A positive Chvostek's sign.

Correct answer: D

Rationale: A positive Chvostek's sign suggests hypocalcemia, which is a post-parathyroidectomy complication and requires prompt treatment. The other options are less urgent: being afebrile with a normal pulse is expected, no bowel movement since surgery can be managed with interventions like early ambulation and stool softeners, and no appetite for breakfast is common postoperatively and can be addressed without immediate provider notification.
