CAT Special Populations & Adaptations 2

Question 1

Which exercise modification is most appropriate for a pregnant client in her third trimester performing aerobics?

Accepted Answer

Avoid supine positions and reduce intensity to RPE 12-14

Answer

In the third trimester, supine positions risk supine hypotensive syndrome, and intensity should stay moderate (RPE 12-14) per ACOG guidelines.

Question 2

A client with osteoporosis wants to join an aerobics class. Which activity poses the HIGHEST fracture risk?

Accepted Answer

High-impact jumping and twisting movements

Answer

High-impact jumping combined with twisting places compressive and rotational forces on already fragile bones, significantly elevating fracture risk.

Question 3

When working with a client who has type 2 diabetes, the instructor should advise checking blood glucose before exercise if levels are:

Accepted Answer

Below 100 mg/dL or above 300 mg/dL

Answer

Exercise is generally contraindicated when blood glucose is below 100 mg/dL (hypoglycemia risk) or above 300 mg/dL (hyperglycemia/ketoacidosis risk).

Question 4

Which RPE range is generally recommended for older adults (65+) during moderate aerobic exercise?

Accepted Answer

11-14 on the Borg 6-20 scale

Answer

An RPE of 11-14 corresponds to light-to-moderate intensity, which is appropriate and safe for most older adult participants.

Question 5

A participant with multiple sclerosis (MS) reports heat sensitivity. The BEST aerobic adaptation is:

Accepted Answer

Exercising in a cool environment and using cooling towels

Answer

Uhthoff's phenomenon in MS causes temporary neurological symptom worsening with heat, so a cool environment minimizes this risk.
