Nursing Elites

1. The nurse is caring for a client with a history of myocardial infarction who is experiencing chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: Corrected Rationale: An electrocardiogram (ECG) should be performed first to assess for cardiac ischemia in a client with a history of myocardial infarction and chest pain. An ECG provides immediate information about the heart's electrical activity, helping to identify changes indicative of cardiac ischemia or infarction. Chest X-ray (Choice B) is not the initial diagnostic test for assessing chest pain related to myocardial infarction. Arterial blood gases (Choice C) are used to assess oxygenation and acid-base balance but are not the primary diagnostic test for myocardial infarction. An echocardiogram (Choice D) may provide valuable information about cardiac structure and function, but it is not the first-line diagnostic test for acute chest pain in a client with a history of myocardial infarction.

2. Following a gunshot wound to the abdomen, a young adult male had an emergency bowel resection and received multiple blood products. His current blood pressure is 78/52 mm Hg, and he is being mechanically ventilated. His oxygen saturation is 87%. Laboratory values indicate hemoglobin of 7 g/dL, platelets of 20,000/mm³, and white blood cells of 2,000/mm³. Which intervention should the nurse implement first?

• A. Transfuse packed red blood cells.
• B. Obtain blood and sputum cultures.
• C. Infuse 1000 ml of normal saline.
• D. Titrate oxygen to keep O2 saturation above 90%.

Correct answer: A

Rationale: The correct answer is to transfuse packed red blood cells first. The client's low hemoglobin level of 7 g/dL indicates severe anemia, which requires immediate transfusion to increase oxygen-carrying capacity. While obtaining blood and sputum cultures (Choice B) is important to identify potential infections, addressing the critical issue of anemia takes precedence. Infusing normal saline (Choice C) may help with volume status but does not address the primary concern of low hemoglobin. Titration of oxygen (Choice D) is crucial, but transfusion to improve oxygen-carrying capacity should be the priority in this scenario.

3. The nurse is assessing a 1-year-old child with bronchiolitis caused by respiratory syncytial virus (RSV). Which assessment finding requires immediate intervention?

• A. Wheezing heard on expiration
• B. Oxygen saturation of 90%
• C. Respiratory rate of 40 breaths per minute
• D. Nasal flaring with sternal retractions

Correct answer: D

Rationale: Nasal flaring with sternal retractions indicates severe respiratory distress in a 1-year-old with bronchiolitis, requiring immediate intervention. Nasal flaring and sternal retractions are signs of increased work of breathing and decreased air movement, indicating the child is struggling to breathe. Wheezing on expiration (Choice A) is common in bronchiolitis but may not require immediate intervention. An oxygen saturation of 90% (Choice B) is low but may not be the most critical finding in this case. A respiratory rate of 40 breaths per minute (Choice C) is elevated but alone may not indicate the need for immediate intervention as much as nasal flaring and sternal retractions.

4. The nurse is caring for a client with chronic heart failure who is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?

• A. Serum potassium of 3.0 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 1.8 mg/dL
• D. Blood glucose of 200 mg/dL

Correct answer: A

Rationale: A serum potassium level of 3.0 mEq/L is most concerning in a client receiving furosemide as it indicates hypokalemia, which requires immediate intervention. Hypokalemia can lead to serious cardiac arrhythmias, which can be life-threatening. Serum sodium of 135 mEq/L and serum creatinine of 1.8 mg/dL are within normal ranges and do not require immediate intervention in this case. Blood glucose of 200 mg/dL is elevated but does not pose an immediate threat to the client's life in the context of heart failure and furosemide therapy.

5. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be closely monitored?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum calcium level

Correct answer: A

Rationale: The correct answer is A: Serum potassium level. When a client with chronic kidney disease is receiving erythropoietin therapy, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant in assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical in this scenario.
