Nursing Elites

1. Alteplase recombinant, or tissue plasminogen activator (t-PA), a thrombolytic enzyme, is administered during the first 6 hours after onset of myocardial infarction (MI) to:

• A. Control chest pain.
• B. Reduce coronary artery vasospasm.
• C. Control the arrhythmias associated with MI.
• D. Revascularize the blocked coronary artery.

Correct answer: D

Rationale: Alteplase recombinant, or t-PA, is a thrombolytic enzyme used to dissolve clots and revascularize the blocked coronary artery in patients experiencing a myocardial infarction (MI). Administering t-PA within the first 6 hours of MI onset is crucial to restore blood flow to the affected area and minimize cardiac tissue damage. Therefore, the correct answer is to revascularize the blocked coronary artery. Choices A, B, and C are incorrect because while controlling chest pain, reducing coronary artery vasospasm, and managing arrhythmias are important goals in managing MI, the primary purpose of administering t-PA within the first 6 hours is to restore blood flow by dissolving clots and revascularizing the blocked coronary artery.

2. Which electrolyte imbalance is most likely to be seen in a patient with chronic kidney disease?

• A. Hypernatremia.
• B. Hyperkalemia.
• C. Hypocalcemia.
• D. Hypokalemia.

Correct answer: B

Rationale: In chronic kidney disease, hyperkalemia is the most common electrolyte imbalance due to the kidneys' reduced ability to excrete potassium. This impaired kidney function leads to potassium retention in the body, resulting in elevated serum potassium levels. Hypernatremia (increased sodium levels) is less likely in chronic kidney disease as the kidneys typically still function to regulate sodium levels. Hypocalcemia (low calcium levels) is not a prominent electrolyte imbalance in chronic kidney disease unless there are additional factors involved. Hypokalemia (low potassium levels) is less common in chronic kidney disease, as the primary issue is usually potassium retention rather than deficiency.

3. A client with acute kidney injury has a blood pressure of 76/55 mm Hg. The health care provider ordered 1000 mL of normal saline to be infused over 1 hour to maintain perfusion. The client is starting to develop shortness of breath. What is the nurse’s priority action?

• A. Calculate the mean arterial pressure (MAP).
• B. Ask for insertion of a pulmonary artery catheter.
• C. Take the client’s pulse.
• D. Slow down the normal saline infusion.

Correct answer: D

Rationale: The nurse should recognize that the client may be developing fluid overload and respiratory distress due to the rapid normal saline infusion. The priority action is to slow down the infusion to prevent worsening respiratory distress and potential fluid overload. While calculating the mean arterial pressure (MAP) is important to assess perfusion, addressing the immediate respiratory distress takes precedence. Inserting a pulmonary artery catheter would provide detailed hemodynamic information but is not the initial step in managing acute respiratory distress. Monitoring vital signs, including the client's pulse, is crucial after adjusting the intravenous infusion to ensure a safe response to the intervention.

4. The nurse is caring for a patient who is receiving isotonic intravenous (IV) fluids at an infusion rate of 125 mL/hour. The nurse performs an assessment and notes a heart rate of 102 beats per minute, a blood pressure of 160/85 mm Hg, and crackles auscultated in both lungs. Which action will the nurse take?

• A. Decrease the IV fluid rate and notify the provider.
• B. Increase the IV fluid rate and notify the provider.
• C. Request an order for a colloidal IV solution.
• D. Request an order for a hypertonic IV solution.

Correct answer: A

Rationale: The patient is showing signs of fluid volume excess, indicated by crackles in both lungs, increased heart rate, and elevated blood pressure. To address this, the nurse should decrease the IV fluid rate and notify the provider. Increasing the IV fluid rate would worsen fluid overload. Requesting colloidal or hypertonic IV solutions would exacerbate the issue by pulling more fluids into the intravascular space, leading to further volume overload.

5. What types of medications should the healthcare provider expect to administer to a client during an acute respiratory distress episode?

• A. Vasodilators and hormones.
• B. Analgesics and sedatives.
• C. Anticoagulants and expectorants.
• D. Bronchodilators and steroids.

Correct answer: D

Rationale: During an acute respiratory distress episode, the priority is to widen air passages, increase air space, and reduce alveolar membrane inflammation. Therefore, the client would likely require bronchodilators to open up the airways and steroids to reduce inflammation. Vasodilators and hormones (Choice A) are not typically indicated in this situation. Analgesics and sedatives (Choice B) may be used for pain management and anxiety but are not primary treatments for respiratory distress. Anticoagulants and expectorants (Choice C) are not the main medications used during an acute respiratory distress episode and may not address the immediate needs of the client.
