Extract:
Question 1 of 5
A nurse is caring for a client who has a central venous catheter and reports hearing a gurgling sound on the side of the catheter insertion. Which of the following complications should the nurse suspect?
Correct Answer: A
Rationale: A gurgling sound suggests partial catheter dislodgment, allowing air entry or fluid leakage, which requires immediate intervention to prevent complications like air embolism.
Question 2 of 5
A nurse is caring for a client who has heart failure and a prescription for digoxin 125 mcg PO daily. Available is digoxin PO 0.25 mg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate: 125 mcg = 0.125 mg; 0.125 mg ÷ 0.25 mg/tablet = 0.5 tablets, ensuring the correct digoxin dose.
