Daily Quad Quiz 3

A physical therapist assistant is treating a patient diagnosed with leukemia who is currently receiving chemotherapy. The patient has been referred to physical therapy to improve their functional mobility and endurance. Which activity would be the LEAST desirable to accomplish the stated goal?

• Yoga

• Bike riding

• Jump roping

• Swimming

Answer explanation

atients with leukemia are at risk for osteonecrosis, which can occur at the hips, knees, and ankles. Patients may or may not present with symptoms related to osteonecrosis and therefore therapists must be aware of potential risk factors. High-impact activities such as jumping rope should be avoided as an intervention to improve endurance since these types of activities place the patient at risk for further injury.

A physical therapist assistant observes a patient utilize a suspensory strategy to regain their balance. Which active movement would be MOST characteristic of this postural strategy?

• Trunk extension

• Hip extension

• Knee flexion

• Ankle plantar flexion

Answer explanation

The suspensory strategy is used to lower the center of gravity during standing or ambulation in order to improve balance and stability. Examples of this strategy include knee flexion, crouching or squatting. This strategy is often used when both mobility and stability are required during a task (e.g., surfing).

Knee flexion is often the immediate action utilized in standing to lower the center of gravity following a significant perturbation. This action often provides the individual with the ability to regain their balance.

A physical therapist assistant performs a gross range of motion screening and determines a patient has excessive medial rotation and limited lateral rotation of the hip. Which alignment of the hip would be the MOST consistent with the identified findings?

• 10 degrees of anteversion

• 18 degrees of anteversion

• 5 degrees of retroversion

• 8 degrees of retroversion

Answer explanation

Femoral anteversion or forward torsion of the femoral neck is measured by the angle of the femoral neck in relation to the femoral condyles. The mean angle of anteversion in an adult is 8-15 degrees.

The amount of femoral anteversion present can be quantified using Craig's test.

8 degrees of anteversion is considered to be excessive and therefore would make the patient more likely to exhibit excessive medial rotation and limited lateral rotation of the hip.

A physical therapist assistant performs gait training with a patient outdoors to simulate the uneven terrain that the patient will encounter upon discharge. The assistant monitors the patient closely due to extreme heat and humidity. What is the PRIMARY mode of heat loss during exercise?

• Convection

• Conduction

• Evaporation

• Radiation

A physical therapist assistant observes the standing posture of a patient from a lateral view. If the patient has normal postural alignment, which of the following anatomical reference points would be MOST appropriate for where the plumb line would fall?

• Posterior to the lobe of the ear

• Slightly anterior to the center of the hip joint

• Slightly anterior to a midline through the knee

• Slightly posterior to the lateral malleolus
