It protects the bacteria from antibiotic and immunologic destruction.
Glycocalyx neutralizes the antibiotic rendering it ineffective.
It competes with the antibiotic for binding sites on the microbe.
Glycocalyx provides nutrients for microbial growth.
They don’t frighten children.
Use of the arms is not restricted.
They cannot be dislodged.
They are difficult to see.
The chemotherapy can be rapidly completed allowing the stomatitis and diarrhea to resolve.
Crystalloid can be administered to prevent dehydration.
Concentrated hyperalimentation fluid can be administered through the CVAD.
The chemotherapy dose can be reduced.
Have an increased risk of infiltration.
Only work a short while because the small bore clots off.
Are beneficial to patient care but are prohibitively expensive.
Allow different medications or solutions to be administered simultaneously.
Lipid residue may accumulate in the CVAD and occlude the catheter.
If the catheter clogs. there is no treatment other than removal and replacement.
Lipids are necessary only in the most extreme cases to prevent essential fatty acid (EFA) deficiency.
Fat emulsions are very caustic.
“You are correct. It is a minor procedure performed on the unit and does not necessitate surgical attire.”
“To decrease the risk of infection. the doctor inserting the PICC will wear a cap. mask. and sterile gown and gloves.”
“It depends on the doctor’s preference.”
“Most doctors only wear sterile gloves. not a cap. mask. or sterile gown.”
“You will have general anesthesia so you won’t feel anything.”
“It will be inserted rapidly. and any discomfort is fleeting.”
“The insertion site will be anesthetized. Threading the catheter through the vein is not painful.”
“You will receive sedation prior to the procedure.”
It is dependent on the patient’s weight and height.
Air entering the patient through a CVAD will follow circulation to the lungs where it will be absorbed and cause no problems.
It is dependent on comorbidities such as asthma or chronic obstructive lung disease.
The sample will be withdrawn into a syringe attached to the portacath needle and then placed into a vacutainer.
Portacath devices are not used to obtain blood samples because of the risk of clot formation.
The vacutainer will be attached to the portacath needle to obtain a direct sample.
Any needle and syringe may be utilized to obtain the sample.
Increases the patient’s comfort level.
Decreases the risk of infection.
Prevents the patient’s clothes from having contact with the catheter
Makes the catheter less visible to other people.
