RPHS CERTIFICATION AND
PRACTICE EXAM QUESTIONS AND
ANSWERS. VERIFIED 2026.
What is the most ergonomic position for a sonographer to be in: - ANS Sitting w elbow close
to the body and wrist in a neutral position
This position will help to decrease muscle fatigue and injury.
When lifting heavy objects: - ANS Keep your back straight and lift w your knees
What document should be available to all office staff that details hazardous materials: -
ANS MSDS
The MSDS should be in a location for al employees to access. This binder should not be
confused w the Exposure Control Plan
An informed consent should: - ANS Detail all risks, benefits and alternatives
Medical records should be maintained: - ANS In accordance w State and Federal guidelines
1 @COPYRIGHT 2025/2026 ALLRIGHTS RESERVED.
,If specific Medicare guidelines are not listed, default to state or federal guidelines
What is the greatest risk to a patient if the txd probe is cracked: - ANS Electrical shock
What is the minimum PPE (personal protective equipment) indicated for a patient w an active
weeping ulcer: - ANS Non-sterile gloves
What is the BEST way to clean a txd probe: - ANS Antibacterial solution
Hazards associated w ultrasound include: - ANS Electrical
Fire
Bio-effects
The calf muscle pump is responsible for ejecting what percentage of lower extremity venous
volume: - ANS 60%
Ankle flexion helps to: - ANS Activate the calf muscle pump
Weight bearing motions will empty the foot. Ankle flexions will activate the calf muscle pump
Primary dysfunction of the calf muscle pump is most likely related to: - ANS Muscle wasting
Stremmer's sign is used to dx: - ANS Lymphedema
Stremmer's sign is a thickened fold of skin at the base of the 2nd toe or second finger that can
be gently pinched and lifted. The presence of this sign is most often an early dx indication of
primary lymphedema; however, it can also develop later in secondary lymphedema

,What is the normal ratio of sclerosant to air for creation of foam ST: - ANS 1:4
Most practitioners will use an air to sclerosant ratio of anywhere between 3:1 and 5:1
A perforating vein is responsible for connecting: - ANS GSV to posterior tibial vein
A perforator vessel is responsible for communication between the superficial and deep venous
systems. Tributaries communicate w in the same system
How long is the ClosureFast catheter's heating element: - ANS 7 cm
There is a 3 mm heating tip now available
How hot does the ClosureFast catheter become: - ANS 120 ° C
How long is each cycle of the ClosureFast treatment: - ANS 20 seconds
How long would it take to treat a 28 cm vein length w ClosureFast? - ANS 80 seconds
How much distance is needed between the heating element and skin to avoid thermal
complications during EVTA? - ANS 1 cm
Having less than 1 cm buffer zone increases the risk of thermal burn to the cutaneous tissues
What stocking has the highest resting pressure: - ANS Long stretch
3 @COPYRIGHT 2025/2026 ALLRIGHTS RESERVED.
, Which stocking has the highest working pressure: - ANS No stretch
NO stretch garments have the highest working pressure as the garment will not stretch against
expansion of the lower extremity muscle during contraction
Which stocking has the highest pressures while walking: - ANS No stretch
NO stretch garments have the highest working pressure as the garment will not stretch against
expansion of the lower extremity muscle during contraction
How should a patient be positioned for SSV ablation: - ANS Prone
Which of the following would be a contraindication to compression stockings: - ANS ABI <0.5
What are the contraindications to stocking wear: - ANS Severe CHF
Septic Phlebitis
ABI <0.5
How much distance is required between the catheter tip and the SFJ: - ANS 2 cm
The catheter tip should also be distal to the superficial inferior epigastric vein. Pay close
attention to how the question is asked
What is the best way to localize the catheter tip of a laser fiber: - ANS PW ultrasound
