C. Routine replacement of central lines every 72 hours
s
D. Chlorhexidine skin antisepsis
am
E. Using sterile technique for dressing changes
Answers: A. Hand hygiene, B. Daily assessment, D. Chlorhexidine, E. Sterile technique
Rationale: Evidence-based prevention includes hand hygiene, chlorhexidine, sterile technique, and removing
unnecessary lines. Routine replacement is not recommended.

Which are appropriate RN responsibilities when caring for a patient with a PICC line?
Select all that apply.
se
☐ Verify tip placement before use
☐ Use sterile technique for dressing changes
ur
☐ Flush with appropriate solution per policy
☐ Allow blood pressure measurements on the PICC arm
☐ Assess for signs of infection
N
Answers: ☑ Verify placement before use, ☑ Use sterile technique for dressing changes, ☑ Flush with appropriate
solution per policy ☑ .Assess for signs of infection
Rationale: Blood pressure should not be taken on the PICC arm due to risk of occlusion or damage.
Which catheter is best for long-term therapy with lower infection risk?
A. Nontunneled catheter
B. PICC
C. Tunneled catheter
,D. Peripheral IV
Answer: C
Rationale: Tunneled catheters (e.g., Hickman, Groshong) are designed for long- term use and have lower infection risk
due to the subcutaneous tunnel.
Which patient would most benefit from a trialysis catheter?
A. Patient requiring long-term antibiotic therapy
B. Patient requiring hemodialysis and IV medication administration
C. Patient needing intermittent chemotherapy
26
D. Patient requiring peripheral parenteral nutrition
Answer: B
20
Rationale: A trialysis catheter has multiple lumens, allowing simultaneous hemodialysis and medication/fluids, making
it ideal for acute renal failure patients.
s
Which sign suggests catheter migration?
am
A. Blood return present
B. External catheter length increased
C. Dry dressing
D. No pain at site
Ex
Answer: B
Rationale: Increased external length indicates movement of the catheter.
s
Which instructions should the nurse include when teaching a patient about home CVAD care?
rt
Select all that apply.
pe
☐ Wash hands before handling the line
☐ Check site daily
☐ Use scissors near tubing
Ex
☐ Keep emergency contact numbers
☐ Avoid submerging the site in water
se
Answers: ☑ Hand hygiene, ☑ Daily checks, ☑ Emergency contacts, ☑ Avoid
submersion

N
, Which statements by a patient with an implanted port (port- Answers: ☑Chemo use, ☑ No daily dressing when not accessed, ☑ Trained staff
a-cath) indicate understanding of care? only, ☑ Under skin
Select all that apply. Rationale: Implanted ports are subcutaneous, accessed with a non-coring needle,and
require trained personnel.
☐"The port can be used for chemotherapy."
☐ "I don't need daily dressing changes when it's not
accessed."
☐"Only trained staff should access the port."
☐ "I can access it myself at home."
☐"It is completely under my skin."

Which finding requires immediate nursing action in a Answer: C
patient with a central line?
Rationale: Sudden dyspnea may indicate air embolism, a life-threatening
complication.
20
A.Mild discomfort at insertion site
B. Slight redness after insertion
C. Sudden shortness of breath
D. Dry dressing
s

C. Swan-Ganz catheter
D.Port-a-cath
se
Which patients are appropriate candidates for a PICC line? Answers: ☑ Long-term antibiotics, ☑ Chemo, ☑ TPN, ☑ Frequent blood draws
ur
Select all that apply. Rationale: PICCs are ideal for long-term therapy, not emergencies.
☐Long-term IV antibiotics
N
☐Vesicant chemotherapy
