Nursing Elites

1. The client with chronic obstructive pulmonary disease (COPD) is receiving supplemental oxygen. Which laboratory value is most concerning?

• A. Serum sodium of 135 mEq/L
• B. Serum potassium of 4.0 mEq/L
• C. Serum bicarbonate of 18 mEq/L
• D. Serum glucose of 300 mg/dl

Correct answer: C

Rationale: A serum bicarbonate level of 18 mEq/L is concerning in a client with COPD receiving supplemental oxygen as it indicates metabolic acidosis, which can occur due to the body compensating for chronic respiratory acidosis. This condition requires immediate intervention to restore the acid-base balance. Choice A, serum sodium of 135 mEq/L, is within normal range (135-145 mEq/L) and not directly related to COPD or oxygen therapy. Choice B, serum potassium of 4.0 mEq/L, falls within the normal range (3.5-5.0 mEq/L) and is not typically affected by COPD or oxygen therapy. Choice D, serum glucose of 300 mg/dl, though elevated, is not directly related to COPD or oxygen therapy and would require management but is not the most concerning value in this scenario.

2. A nurse is preparing to administer a dose of digoxin (Lanoxin) to a client with heart failure. Which assessment finding requires immediate intervention?

• A. Apical pulse of 58 beats per minute
• B. Blood pressure of 110/70 mmHg
• C. Presence of a new murmur
• D. Respiratory rate of 18 breaths per minute

Correct answer: A

Rationale: An apical pulse of 58 beats per minute is concerning when administering digoxin because digoxin can further lower the heart rate, leading to bradycardia or heart block. Immediate intervention is required to prevent potential complications. A blood pressure of 110/70 mmHg is within normal range and does not require immediate intervention in this context. The presence of a new murmur may indicate valvular issues but does not directly relate to the administration of digoxin. A respiratory rate of 18 breaths per minute is also within normal limits and is not a priority concern when administering digoxin.

3. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?

• A. 50 ml/hour
• B. 25 ml/hour
• C. 75 ml/hour
• D. 100 ml/hour

Correct answer: C

Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.

4. The nurse is caring for a client with diabetic ketoacidosis (DKA). Which intervention is most important?

• A. Administer insulin as prescribed.
• B. Monitor the client's urine output.
• C. Assess the client's level of consciousness.
• D. Obtain an arterial blood gas (ABG) sample.

Correct answer: A

Rationale: Administering insulin is the most crucial intervention in managing diabetic ketoacidosis. Insulin helps reduce blood glucose levels and correct metabolic acidosis, which are the primary issues in DKA. Monitoring urine output (Choice B) is important but not as critical as administering insulin. Assessing the client's level of consciousness (Choice C) is essential but does not directly address the underlying cause of DKA. Obtaining an arterial blood gas sample (Choice D) can provide valuable information but is not as urgent as administering insulin to address the immediate metabolic imbalance.

5. 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.
