Nursing Elites

1. The nurse is assessing the thorax and lungs of a client who is experiencing respiratory difficulty. Which finding is most indicative of respiratory distress?

• A. Contractions of the sternocleidomastoid muscle.
• B. Respiratory rate of 20 breaths/min
• C. Downward movement of diaphragm with inspiration
• D. A pulse oximetry reading of SpO2 95%

Correct answer: A

Rationale: The correct answer is A: Contractions of the sternocleidomastoid muscle. Contractions of the sternocleidomastoid muscle suggest that the client is using accessory muscles to breathe, which is a clear sign of respiratory distress. This finding indicates that the client is working harder to breathe, typically seen in conditions like asthma, COPD, or respiratory failure. Choices B, C, and D are not the most indicative of respiratory distress. A respiratory rate of 20 breaths/min falls within the normal range. Downward movement of the diaphragm with inspiration is a normal finding indicating effective diaphragmatic breathing. A pulse oximetry reading of SpO2 95% is within the normal range and does not necessarily indicate respiratory distress.

2. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which clinical finding is most concerning?

• A. Peaked T waves on the ECG
• B. Bradycardia
• C. Muscle weakness
• D. Decreased deep tendon reflexes

Correct answer: A

Rationale: Peaked T waves on the ECG are the most concerning finding in a client with hyperkalemia. Hyperkalemia can lead to serious cardiac complications, including arrhythmias and cardiac arrest. Peaked T waves are a classic ECG finding associated with hyperkalemia and indicate the need for immediate intervention. Bradycardia, muscle weakness, and decreased deep tendon reflexes can also be seen in hyperkalemia, but the presence of peaked T waves signifies a higher risk of cardiac events, making it the most concerning finding in this scenario.

3. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding requires immediate intervention?

• A. Serum glucose of 300 mg/dL
• B. Serum potassium of 5.5 mEq/L
• C. Serum bicarbonate of 18 mEq/L
• D. Positive urine ketones

Correct answer: C

Rationale: A serum bicarbonate level of 18 mEq/L indicates metabolic acidosis in a client with DKA, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis, which is reflected by a low serum bicarbonate level. Correcting the low serum bicarbonate is crucial to normalize the metabolic acidosis and improve the client's condition. While elevated serum glucose (choice A) and urine ketones (choice D) are characteristic of DKA, addressing the metabolic acidosis takes precedence. Serum potassium (choice B) levels may also need monitoring and management, but correcting the acidosis is the priority to prevent complications like cardiovascular collapse.

4. A client with a history of type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which intervention is most important?

• A. Administer intravenous fluids as prescribed.
• B. Administer insulin as prescribed.
• C. Monitor the client's urine output.
• D. Check the client's blood glucose level.

Correct answer: B

Rationale: Administering insulin is the most important intervention in managing diabetic ketoacidosis. Insulin helps to reduce blood glucose levels and correct metabolic acidosis, which are critical in the treatment of DKA. While administering intravenous fluids is essential to manage dehydration, insulin takes precedence in treating the underlying cause of DKA. Monitoring urine output is important for assessing renal function but is not the primary intervention in managing DKA. Checking the client's blood glucose level is necessary, but administering insulin to reduce high blood glucose levels is the key priority in treating DKA.

5. A client with a history of myocardial infarction is admitted with chest pain. Which laboratory value should the nurse monitor closely?

• A. White blood cell count
• B. Serum creatinine
• C. Troponin level
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C: Troponin level. Troponin levels should be closely monitored in a client with chest pain and a history of myocardial infarction to assess for ongoing myocardial injury. Troponin is a specific marker for myocardial damage. Monitoring white blood cell count (choice A) is not directly related to myocardial infarction. Serum creatinine (choice B) is more indicative of renal function rather than cardiac status. Hemoglobin level (choice D) is important but does not directly reflect ongoing myocardial injury.
