Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value is most concerning?

• A. Serum potassium of 6.5 mEq/L
• B. Serum bicarbonate of 18 mEq/L
• C. Serum glucose of 350 mg/dl
• D. Serum sodium of 135 mEq/L

Correct answer: A

Rationale: A serum potassium level of 6.5 mEq/L is concerning in a client with COPD exacerbation as it may lead to life-threatening arrhythmias, requiring immediate intervention. Hyperkalemia can cause cardiac arrhythmias, which pose a significant risk to the patient's life. Options B, C, and D are not typically associated with immediate life-threatening risks in the context of a COPD exacerbation.

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. During the initial newborn assessment, the nurse finds that a newborn's heart rate is irregular. Which intervention should the nurse implement?

• A. Notify the pediatrician immediately.
• B. Teach the parents about congenital heart defects.
• C. Document the finding in the infant's record.
• D. Apply oxygen via nasal cannula at 3 L/min.

Correct answer: C

Rationale: The correct intervention when a nurse finds an irregular heart rate in a newborn is to document the finding in the infant's record. An irregular heart rate is a common occurrence in newborns and does not necessarily require immediate medical intervention. Notifying the pediatrician immediately is unnecessary unless there are other concerning symptoms. Teaching the parents about congenital heart defects is not the priority in this situation. Applying oxygen via nasal cannula at 3 L/min is not indicated for an irregular heart rate without further assessment or medical indication.

4. A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which assessment finding is most concerning?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 24 breaths per minute
• C. Use of accessory muscles
• D. Inspiratory crackles

Correct answer: C

Rationale: The correct answer is C. Use of accessory muscles is the most concerning finding in a client with COPD experiencing an exacerbation. This indicates increased work of breathing and can be a sign of respiratory failure, requiring immediate intervention. Oxygen saturation of 90% is low but not as concerning as the increased work of breathing. A respiratory rate of 24 breaths per minute can be within normal limits. Inspiratory crackles may be present in COPD due to airway inflammation but are not as concerning as the use of accessory muscles.

5. After multiple attempts to stop drinking, an adult male is admitted to the medical intensive care unit (MICU) with delirium tremens. He is tachycardic, diaphoretic, restless, and disoriented. Which finding indicates a life-threatening condition?

• A. Widening QRS complexes and flat T waves
• B. Tachycardia and elevated blood pressure
• C. Restlessness and anxiety
• D. Diaphoresis and dehydration

Correct answer: A

Rationale: The correct answer is A: Widening QRS complexes and flat T waves. In the context of an adult male with delirium tremens and symptoms like tachycardia, diaphoresis, restlessness, and disorientation, the presence of widening QRS complexes and flat T waves on an ECG suggests severe electrolyte imbalance, particularly hypokalemia. This severe electrolyte imbalance can lead to life-threatening arrhythmias such as ventricular tachycardia or fibrillation. Tachycardia and elevated blood pressure (choice B) can be expected in delirium tremens but do not directly indicate a life-threatening condition as widening QRS complexes and flat T waves do. Restlessness and anxiety (choice C) are common symptoms of delirium tremens but do not specifically signify a life-threatening condition. Diaphoresis and dehydration (choice D) are also common in delirium tremens but do not directly point towards a life-threatening electrolyte imbalance as widening QRS complexes and flat T waves do.
