PT (prothrombin time)

Get a hint
Hint

time it takes for a blood sample to coagulate after thromboplastin and calcium are added; detects clotting abnormalities of the extrinsic pathway

indicates the likelihood of a patient to have a bleeding or clotting problem during or after surgery

Normal values are between 10-13 seconds

measures the time it takes a clot to form and is also used to evaluate the effects of heparin therapy.

PT (prothrombin time)

time it takes for a blood sample to coagulate after thromboplastin and calcium are added; detects clotting abnormalities of the extrinsic pathway

indicates the likelihood of a patient to have a bleeding or clotting problem during or after surgery

Normal values are between 10-13 seconds

New cards

PTT (parietal thromboplastin time)

measures the time it takes a clot to form and is also used to evaluate the effects of heparin therapy.

3
New cards

INR (international normalized rate)

method developed to standardize PT results among laboratories by accounting for the different thromboplastin reagents used to determine PT

4
New cards

What is the best approach for a thoracentesis?

subcostal; reduces the risk of a pneumothorax

5
New cards

What is the most common indication for a biopsy?

to confirm if a mass is malignant.

6
New cards

advantages of using ultrasound for biopsy?

main advantage: continuous real-time visualization of the needle

biopsy malignant or benign masses

drain various fluid collections (cysts, joint effusions, ascites, pleural fluid)

mark spots for fluid taps to be performed without direct sono guidance

7
New cards

contraindications / risks of having a procedure:

uncorrectable bleeding disorder, lack of a safe needle pathway, uncooperative patient ( risk of complication for pt and sonographer/ sonologist by needle stick)

8
New cards

PSA (prostate specific antigen)

evaluate the prostate for cancer

9
New cards

AFP (alpha- fetoprotein)

elevation could indicate a liver lesion

10
New cards

needle type used for paracentesis

centesis catheter

ascites

11
New cards

What is administered after a significant amount of fluid is removed by paracentesis?

Albumin

and patient may need a platelet transfusion

12
New cards

What instances would you use a core biopsy?

to remove larger core tissue samples for histologic analysis.

also called a biopsy gun.

13
New cards

FNA (fine needle aspiration)

thin-gauge needles to obtain cells from within the mass.

performed using a 20-25 gauge needle.

14
New cards

2 advantages of having a cytopathology team

increases the number of successful biopsies

helps to minimize the number of passes

reduces overall procedure time

15
New cards

what does the cytopathologist determine:

looks at the slides to determine if the material is diagnostic

16
New cards

What is a time out?

the national patient safety standards mandate that a “time-out” be performed before beginning any procedure.

pt recites full name and reason they are there. pt ID or history number is confirmed along with type and location of procedure. must be documented and may be a part of the consent form or filled out in the pt electronic record.

17
New cards

types of transducers

linear, curved linear, phased array

linear: surface

curved linear: deeper

phased: limited FOV

18
New cards

Local anesthetic needle gauge

25 gauge needle

19
New cards

Post op complications:

postprocedural pain or discomfort

vasovagal reaction

hematoma

bleeding

seeding of the needle track

serious complications: hemorrhage, pneumothorax, pancreatitis, infection, death.

20
New cards

What is the spleen a high risk for?

Hemorrhage

21
New cards

what does the diaphragm separate?

the chest cavity from the abdominal cavity
