Nursing Elites

1. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?

• A. Serum creatine kinase (CK)
• B. Serum troponin
• C. Serum myoglobin
• D. C-reactive protein (CRP)

Correct answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

2. A client with end-stage renal disease (ESRD) is receiving hemodialysis. Which laboratory value should the nurse monitor closely?

• A. Serum calcium level of 9 mg/dl
• B. Serum potassium level of 4.5 mEq/L
• C. Serum creatinine level of 2.0 mg/dl
• D. Serum sodium level of 138 mEq/L

Correct answer: C

Rationale: The correct answer is C: Serum creatinine level of 2.0 mg/dl. In a client with ESRD receiving hemodialysis, serum creatinine should be closely monitored. Elevated creatinine levels indicate impaired kidney function. Monitoring serum calcium levels (Choice A), serum potassium levels (Choice B), and serum sodium levels (Choice D) is also important in clients with ESRD, but the most crucial indicator of kidney function in this case is serum creatinine.

3. The practical nurse (PN) is assigned to work with three registered nurses (RNs) who are caring for neurologically compromised clients. The client with which change in status is best to assign to the PN?

• A. Diabetic ketoacidosis with a Glasgow Coma Scale score change from 10 to 7.
• B. Myxedema coma with a blood pressure change from 80/50 to 70/40.
• C. Viral meningitis with a temperature change from 101°F to 102°F.
• D. Subdural hematoma with a blood pressure change from 150/80 to 170/60.

Correct answer: C

Rationale: The client with viral meningitis and a temperature change is the most stable and appropriate for assignment to the PN. A change in temperature from 101°F to 102°F is not as critical as changes in Glasgow Coma Scale score, blood pressure, or wider blood pressure variations. The other clients require more complex monitoring and intervention due to their critical changes in status.

4. The nurse enters a client's room to administer scheduled daily medications and observes the client leaning forward and using pursed lip breathing. Which action is most important for the nurse to implement first?

• A. Evaluate the oxygen saturation.
• B. Administer a bronchodilator.
• C. Assist the client to sit upright.
• D. Encourage slow, deep breathing.

Correct answer: A

Rationale: In this scenario, the nurse should first evaluate the oxygen saturation. This action is crucial as it provides immediate information on the client's respiratory status. Assessing the oxygen saturation can help determine the adequacy of oxygenation and guide further interventions. Administering a bronchodilator (Choice B) may be necessary based on assessment findings, but it should not be the first action without knowing the oxygen saturation level. While assisting the client to sit upright (Choice C) is generally beneficial for respiratory function, in this case, assessing oxygen saturation takes precedence. Encouraging slow, deep breathing (Choice D) can be helpful, but it is secondary to evaluating the oxygen saturation in this situation.

5. The nurse is caring for a client with acute respiratory distress syndrome (ARDS) who is receiving mechanical ventilation. Which assessment finding requires immediate intervention?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 28 breaths per minute
• C. Tidal volume of 300 ml
• D. Blood pressure of 110/70 mmHg

Correct answer: C

Rationale: The correct answer is C. A tidal volume of 300 ml is concerning in a client with ARDS on mechanical ventilation because it indicates hypoventilation, which can lead to inadequate gas exchange and worsening respiratory status. This finding requires immediate intervention to optimize ventilation and oxygenation. Options A, B, and D are not as critical in this scenario. An oxygen saturation of 90% may be acceptable depending on the client's baseline condition and the target range set by the healthcare provider. A respiratory rate of 28 breaths per minute is slightly elevated but may not be immediately alarming. A blood pressure of 110/70 mmHg is within normal limits and does not require urgent intervention.
