Nursing Elites

1. After the administration of t-PA, what should the nurse do?

• A. Observe the client for chest pain.
• B. Monitor for fever.
• C. Review the 12-lead electrocardiogram (ECG).
• D. Auscultate breath sounds.

Correct answer: A

Rationale: After the administration of t-PA, the nurse should observe the client for chest pain. Chest pain post t-PA administration could indicate reocclusion of the coronary artery, a serious complication that requires immediate intervention. Monitoring for fever (choice B) is not specifically associated with t-PA administration. While reviewing the 12-lead ECG (choice C) is important for assessing cardiac function, it may not be the immediate priority right after t-PA administration. Auscultating breath sounds (choice D) is important for assessing respiratory status but is not the most crucial assessment following t-PA administration.

2. A client with chronic renal failure is being treated with sodium polystyrene sulfonate (Kayexalate). The nurse should monitor the client for which of the following?

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

Correct answer: C

Rationale: The correct answer is C: Hyperkalemia. Sodium polystyrene sulfonate (Kayexalate) is used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the large intestine, which is then eliminated through the feces. Therefore, the nurse should monitor the client for changes in potassium levels to ensure the effectiveness of the treatment. Choices A, B, and D are incorrect because sodium polystyrene sulfonate (Kayexalate) is not associated with causing hyponatremia, hypokalemia, or hypocalcemia.

3. A client has lost a significant amount of blood due to complications during surgery. What parameter does the nurse recognize as the earliest indication of new decreases in fluid volume?

• A. Pulse rate
• B. Blood pressure
• C. Pulmonary artery systolic pressure
• D. Pulmonary artery end-diastolic pressure

Correct answer: A

Rationale: The earliest indication of new decreases in fluid volume is often recognized by an increase in pulse rate. Cardiac output is influenced by circulating blood volume, heart pumping action, and vascular tone. As fluid volume decreases, the body compensates by increasing the pulse rate. The formula for cardiac output is pulse rate multiplied by stroke volume. An elevated pulse rate helps maintain blood pressure with minor volume depletion. Pulmonary artery systolic pressure and pulmonary artery end-diastolic pressure, obtained through a pulmonary artery catheter, provide insights into pulmonary artery and left ventricle pressures at the end of diastole. These parameters are not the earliest indicators of new decreases in fluid volume compared to pulse rate.

4. 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.

5. A healthcare professional is reviewing laboratory results for a client who is at risk for nephrotoxicity due to medications. Which of the following serum creatinine results does the healthcare professional document as normal?

• A. 0.2 mg/dL
• B. 1.0 mg/dL
• C. 2.8 mg/dL
• D. 3.9 mg/dL

Correct answer: B

Rationale: The normal serum creatinine level typically ranges from 0.6 to 1.3 mg/dL. A result of 1.0 mg/dL falls within this normal range. A serum creatinine level of 0.2 mg/dL is abnormally low and may indicate decreased muscle mass or malnutrition. On the other hand, results of 2.8 mg/dL and 3.9 mg/dL are elevated, signifying impaired kidney function and potential nephrotoxicity from medications.
