Nursing Elites

1. The nurse is caring for a client with chronic heart failure who is receiving digoxin therapy. The nurse reviews the client's lab results and notes that the serum potassium level is 3.0 mEq/L. What action should the nurse take next?

• A. Administer a potassium supplement
• B. Notify the healthcare provider
• C. Hold the next dose of digoxin
• D. Increase dietary potassium intake

Correct answer: C

Rationale: In clients receiving digoxin therapy, low potassium levels can increase the risk of digoxin toxicity. Therefore, when the nurse notes a serum potassium level of 3.0 mEq/L, it is crucial to hold the next dose of digoxin. Notifying the healthcare provider is essential to ensure appropriate interventions, such as potassium supplementation, can be implemented. Administering a potassium supplement without healthcare provider guidance may lead to rapid potassium level changes and potential adverse effects. Increasing dietary potassium intake alone may not promptly address the low serum potassium level in this acute situation.

2. A client with type 1 diabetes mellitus is admitted to the emergency department with confusion, sweating, and a blood sugar level of 45 mg/dL. What is the nurse's priority action?

• A. Administer 50% dextrose IV push
• B. Provide a carbohydrate snack
• C. Check the client's urine for ketones
• D. Start an insulin drip

Correct answer: A

Rationale: A blood sugar level of 45 mg/dL indicates severe hypoglycemia, which can lead to life-threatening complications if not treated immediately. The priority is to administer IV dextrose to rapidly increase the blood sugar level. Administering 50% dextrose IV push will provide a quick source of glucose to raise the blood sugar. Providing a carbohydrate snack is not the immediate priority in this critical situation. Checking the client's urine for ketones is important in diabetic ketoacidosis, not for hypoglycemia. Starting an insulin drip would further lower the blood sugar and worsen the client's condition.

3. The nurse is taking the blood pressure measurement of a client with Parkinson's disease. Which information in the client's admission assessment is relevant to the nurse's plan for taking the blood pressure reading?

• A. Frequent syncope
• B. Muscle rigidity
• C. Gait instability
• D. Fine motor tremors

Correct answer: A

Rationale: The correct answer is A: 'Frequent syncope.' Orthostatic hypotension, common in Parkinson's disease, often causes syncope (fainting) when blood pressure drops upon standing. This information is critical for planning safe blood pressure measurements, ensuring readings are taken in both lying and standing positions to assess for sudden drops in pressure. Muscle rigidity, tremors, or gait instability are important symptoms in Parkinson's disease but are not directly related to blood pressure assessment.

4. A client is admitted with an epidural hematoma after a skateboarding accident. How should the nurse differentiate the vascular source of intracranial bleeding?

• A. Monitor for clear fluid leakage from the nose.
• B. Assess for rapid onset of decreased level of consciousness.
• C. Check for bruising around the head and neck.
• D. Assess for changes in pupil size and reactivity.

Correct answer: B

Rationale: An epidural hematoma is characterized by a rapid onset of symptoms, including decreased level of consciousness, due to arterial bleeding, which differentiates it from other types of intracranial hemorrhage. Monitoring for clear fluid leakage from the nose (choice A) is more indicative of a basilar skull fracture and cerebrospinal fluid leak. Checking for bruising around the head and neck (choice C) is more suggestive of soft tissue injuries or facial fractures. Assessing for changes in pupil size and reactivity (choice D) is essential in evaluating traumatic brain injuries, but it is not specific to differentiating the vascular source of intracranial bleeding in an epidural hematoma.

5. A nurse from the maternity unit is floated to the critical care unit because of staff shortage on the evening shift. Which client would be appropriate to assign to this nurse?

• A. A client with a Dopamine drip IV with vital signs monitored every 5 minutes
• B. A client with a myocardial infarction that is free from pain and dysrhythmias
• C. A client with a tracheotomy of 24 hours in some respiratory distress
• D. A client with a pacemaker inserted this morning with intermittent capture

Correct answer: B

Rationale: In this scenario, it is more appropriate to assign a stable client, such as the one with a myocardial infarction who is free from pain and dysrhythmias, to a nurse who lacks specialized critical care experience. This client's condition is relatively stable and does not require immediate critical interventions. Choices A, C, and D involve clients with more complex and critical conditions that would be better managed by a nurse with specialized critical care training. Choice A involves a client on a Dopamine drip with frequent vital sign monitoring, Choice C has a client with a tracheotomy in respiratory distress, and Choice D describes a client with a pacemaker experiencing intermittent capture, all of which require a higher level of critical care expertise.
