Nursing Elites

1. 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.

2. A client's chest tube insertion site has crepitus (crackling sensation) upon palpation. What is the nurse's next step?

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

Correct answer: D

Rationale: The correct next step for the nurse is to measure the area of crepitus. Crepitus indicates subcutaneous emphysema, which is a serious condition requiring monitoring. Applying a pressure dressing (Choice A) could worsen the condition by trapping air under the skin. Administering an oral antihistamine (Choice B) is not indicated for crepitus. Assessing for allergies to cleaning agents (Choice C) is not the priority when dealing with crepitus and subcutaneous emphysema.

3. A client with a head injury reports severe nausea. What is the nurse's priority action?

• A. Administer anti-nausea medication as prescribed.
• B. Prepare the client for a CT scan.
• C. Elevate the head of the bed and provide an emesis basin.
• D. Notify the healthcare provider immediately.

Correct answer: D

Rationale: Severe nausea in a client with a head injury may be a sign of increased intracranial pressure. The nurse should notify the healthcare provider immediately to ensure timely intervention, as increased pressure can lead to further complications such as brain herniation. Administering anti-nausea medication or preparing for a CT scan may delay necessary treatment for the underlying cause of the nausea, which could be related to the head injury. Elevating the head of the bed and providing an emesis basin may help manage symptoms but should not be the priority over addressing the potential increase in intracranial pressure.

4. A male client with HIV on antiretroviral therapy complains of constant hunger and thirst while losing weight. What action should the nurse implement?

• A. Check the client's glucose level with a glucometer.
• B. Measure the client's weight accurately.
• C. Reassure the client that weight will stabilize as viral load decreases.
• D. Increase the dose of saquinavir.

Correct answer: A

Rationale: The correct action for the nurse to implement is to check the client's glucose level with a glucometer. Constant hunger and thirst along with weight loss can be indicative of hyperglycemia, a possible side effect of saquinavir. Monitoring the client's glucose levels is crucial in this situation. Measuring the client's weight accurately (Choice B) is important for monitoring purposes but does not address the immediate concern of hunger, thirst, and weight loss. Reassuring the client that weight will stabilize as viral load decreases (Choice C) is not appropriate in this scenario as the symptoms described need immediate attention. Increasing the dose of saquinavir (Choice D) without assessing the client's glucose level can worsen the hyperglycemia.

5. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.
