Instructions

Work through each question carefully to choose the best answer, and submit the quiz to view your results. After completing the quiz, read through the answer explanations to review the reasoning behind both correct and incorrect options.

1

Which of the following is a primary indication for femoral central venous catheterization?

Administration of oral medications in a fasting patient
Short-term hydration in mild dehydration
Infusion of vasoactive drugs requiring central access
Venous sampling in a stable outpatient

2

A patient in hemorrhagic shock has a healing surgical wound and signs of local infection in the right groin. What is the best decision regarding femoral line insertion?

Proceed with careful femoral access on the right to save time
Delay access until infection has fully resolved
Choose the left femoral site if it is clean and infection-free
Insert through the same groin after swabbing with antiseptic

3

Which of the following statements best reflects clear and patient-centered communication when obtaining consent?

“We’ll insert a line for treatment; it’s standard, nothing to worry about.”
“We’ll place a line in your groin to help deliver important medications safely, and I’ll explain what to expect.”
“This is a routine hospital procedure and usually goes fine.”
“You’ll need to sign consent before we begin, but it won’t take long.”

4

A patient in the ICU needs reliable access for routine medication infusions. The operator selects a triple-lumen central venous catheter from the emergency resuscitation kit. What aspect of this choice is most concerning?

The femoral site is unsuitable for any central venous procedure
The number of lumens makes the catheter prone to blockage
The catheter may be larger than necessary for the patient’s treatment needs
The operator should have used a subclavian approach instead

5

A patient with severe trauma requires rapid fluid resuscitation. Peripheral access attempts have failed, and there is no groin infection or thrombosis. What is the most appropriate next step?

Proceed with femoral central line insertion to secure access
Wait for imaging before deciding on femoral insertion
Insert a jugular line immediately without assessing landmarks
Delay central access and continue attempting peripheral lines
