Nursing Elites

1. The nurse is preparing a 50 ml dose of 50% dextrose IV for a client with insulin shock. What is the most immediate intervention by the nurse?

• A. Dilute the dextrose in one liter of 0.9% Normal Saline solution.
• B. Mix the dextrose in a 50 ml piggyback for a total volume of 100 ml.
• C. Push the undiluted dextrose slowly through the current IV infusion.
• D. Ask the pharmacist to add the dextrose to a TPN solution.

Correct answer: C

Rationale: The correct immediate intervention by the nurse in this situation is to push the undiluted 50% dextrose slowly through the current IV infusion. This is because in cases of insulin shock, where the client has dangerously low blood sugar levels, administering 50% dextrose directly into the bloodstream helps rapidly increase blood glucose levels. Choice A is incorrect because diluting the dextrose in one liter of normal saline would delay the administration of glucose, which is needed urgently. Choice B is incorrect as mixing the dextrose in a piggyback solution would also delay the administration of the concentrated dextrose. Choice D is incorrect because adding dextrose to a TPN solution is not the immediate intervention needed to address the low blood sugar levels in a client experiencing insulin shock.

2. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.

3. The nurse is assessing a client with chronic heart failure who is receiving furosemide (Lasix). Which assessment finding is most concerning?

• A. Heart rate of 60 beats per minute
• B. Blood pressure of 110/70 mmHg
• C. Elevated liver enzymes
• D. Elevated blood glucose level

Correct answer: C

Rationale: Elevated liver enzymes are most concerning in a client with chronic heart failure as they may indicate liver congestion or worsening heart failure, requiring immediate intervention. Elevated liver enzymes can be a sign of hepatotoxicity or liver damage, which could be a result of furosemide (Lasix) use. Monitoring liver function is crucial in patients taking furosemide due to the risk of hepatotoxicity. A heart rate of 60 beats per minute and a blood pressure of 110/70 mmHg are within normal ranges for a client with chronic heart failure. An elevated blood glucose level may be expected due to the effects of furosemide but is not as immediately concerning as elevated liver enzymes.

4. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which intervention should the nurse implement first?

• A. Administer a bronchodilator as prescribed.
• B. Assess the client's respiratory rate.
• C. Assess the client's oxygen saturation.
• D. Elevate the head of the bed.

Correct answer: C

Rationale: Assessing the client's oxygen saturation is crucial in a client with COPD receiving supplemental oxygen to ensure adequate oxygenation. This assessment helps determine if the current oxygen therapy is effective or if adjustments are necessary. While administering a bronchodilator is important in managing COPD, assessing oxygen saturation takes precedence to address the client's immediate oxygen needs. Assessing the respiratory rate is also important but evaluating oxygen saturation provides more direct information about the client's oxygen status. Elevating the head of the bed can improve ventilation but is not the priority when assessing oxygen saturation in a client with COPD receiving supplemental oxygen.

5. A client with a spinal cord injury is admitted to the ICU. Which nursing intervention is most important to include in this client's plan of care?

• A. Monitor for signs of autonomic dysreflexia.
• B. Implement measures to prevent pressure ulcers.
• C. Perform passive range of motion exercises.
• D. Ensure that the client is turned every two hours.

Correct answer: A

Rationale: The correct answer is A: Monitor for signs of autonomic dysreflexia. Autonomic dysreflexia is a life-threatening condition that can occur in clients with spinal cord injuries, especially those with injuries above the T6 level. It is characterized by a sudden onset of excessively high blood pressure, pounding headache, profuse sweating, and flushing above the level of injury. Failure to recognize and treat autonomic dysreflexia promptly can lead to seizures, stroke, or even death. Therefore, monitoring for signs of autonomic dysreflexia is crucial in clients with spinal cord injuries. Choices B, C, and D are important interventions too, but in the context of a spinal cord injury, monitoring for autonomic dysreflexia takes priority due to its potentially life-threatening nature.
