Extract:
Question 1 of 5
The nurse is caring for a client with a complete heart block. The nurse should question which of the following orders?
Correct Answer: A
Rationale: Lidocaine suppresses ventricular activity, which could worsen complete heart block by reducing the ventricular escape rhythm. Options B, C, and D are appropriate: atropine increases heart rate, pacemakers treat persistent bradycardia, and isoproterenol supports severe bradycardia.
Question 2 of 5
The nurse is caring for a client with a history of chronic obstructive pulmonary disease (COPD).
Correct Answer: B
Rationale: Chronic COPD causes CO2 retention, leading to a compensated respiratory acidosis with low pH (7.32), high PaCO2 (50 mmHg), and low PaO2 (70 mmHg) due to impaired gas exchange. Normal or acute values are incorrect.
Question 3 of 5
The nurse is caring for a client with a history of atrial fibrillation who is receiving digoxin (Lanoxin) 0.125 mg PO daily. Which of the following laboratory results would be of GREATest concern to the nurse?
Correct Answer: A
Rationale: Hypokalemia (potassium 3.0 mEq/L) increases the risk of digoxin toxicity, which can cause life-threatening arrhythmias in atrial fibrillation. Options B, C, and D are normal: sodium 140 mEq/L, magnesium 2.0 mEq/L, and calcium 9.0 mg/dL do not affect digoxin.
Question 4 of 5
Which of the following infants is in need of additional growth assessment?
Correct Answer: B
Rationale: Baby B has gained only 1 oz. in 2 weeks, indicating poor growth (normal is 0.5-1 oz./day). Others show appropriate weight gain.
Question 5 of 5
A client is receiving an intravenous (IV) infusion for pain control. When caring for this client, which one of these actions can the RN safely assign to an unlicensed assistive personnel (UAP)?
Correct Answer: D
Rationale: When directing the UAP, communicate clearly and specifically what the task is and what should be reported to the nurse. Implementation of routine tasks should be delegated since they do not require independent judgment.
