What is the recommended ratio of compression to ventilation during adult CPR performed by two healthcare providers?
Answer: 30:2
For two-rescuer adult CPR, the recommended compression-to-ventilation ratio is 30:2. This ratio ensures adequate blood flow while providing necessary oxygenation through ventilation.
An athletic trainer is designing a rehabilitation program for an athlete recovering from ACL reconstruction. During which phase should closed kinetic chain exercises be emphasized?
Answer: Intermediate rehabilitation (Week 6-12)
Closed kinetic chain exercises (squats, leg press, step-ups) are emphasized during the intermediate phase of ACL rehabilitation because they produce less anterior tibial shear force than open chain exercises while promoting functional strength.
Which taping technique is most commonly used to prevent recurrent lateral ankle sprains?
Answer: Closed basket weave with heel locks and figure-8s
The closed basket weave technique with heel locks and figure-8s is the standard prophylactic ankle taping method. It provides mechanical support against excessive inversion and eversion while allowing functional dorsiflexion and plantar flexion.
What is the recommended temperature range for a therapeutic whirlpool used for warm water immersion treatment?
Answer: 98-104 degrees F (37-40 degrees C)
The recommended warm whirlpool temperature is 98-104 degrees F (37-40 degrees C). This range provides therapeutic heating effects while minimizing the risk of burns. Higher temperatures are used for extremity immersion only.
An athlete sustains a Grade II MCL sprain. What is the expected timeline for return to full activity?
Answer: 4-8 weeks
A Grade II MCL sprain (partial tear) typically requires 4-8 weeks for return to full activity. This accounts for ligament healing, rehabilitation of strength and stability, and functional progression.
Which electrotherapy modality uses a continuous waveform to produce deep tissue heating through conversion of electrical energy?
Answer: Therapeutic ultrasound
Therapeutic ultrasound uses continuous high-frequency sound waves that are absorbed by tissues and converted to heat (thermal effect). The continuous mode produces the deep heating effects, while pulsed mode emphasizes non-thermal effects.
