Question 1
Which statement describes the associative stage of motor learning?
Correct Answer:
Fine-Tuning Of Skills, Making Them Consistent, Efficient, Increasing Speed, And Problem-Solving.
Explanation:
In motor learning, the associative stage is when practice has moved you beyond rough trial-and-error and you start refining the movement. Movements become smoother and more consistent, you perform them more efficiently, and you can often increase speed while still solving small problems in how you execute the skill. This refinement and problem-solving focus is exactly what the statement describes. By contrast, becoming automatic happens in the later autonomous stage, where the skill can be performed with minimal conscious thought. Needing to think about the movement characterizes the cognitive stage, and distractions hindering progress is a general factor that can affect any stage, not a defining feature of this middle phase.
Question 2
Balance is greatest when the body's center of mass is maintained over base of support. Which option correctly completes this statement?
Correct Answer:
Base of support
Explanation:
Balance hinges on where the body's center of mass is in relation to the base of support. When the vertical line through the center of mass falls inside the base of support—the area bounded by the parts of the body in contact with the ground—the gravitational moment tends to keep you upright and small muscle adjustments can maintain stability. If that line shifts toward or beyond the edge, tipping occurs and you must react, often by shifting weight or taking a step. The base of support is simply the region on the ground covered by your contact points. So balance is greatest when the center of mass is over the base of support.
Question 3
During healing, which contraction type should generally be avoided until there are no adverse tissue effects?
Correct Answer:
Eccentric contractions
Explanation:
Eccentric contractions should be avoided early in healing because they place high tensile forces on repair tissue as the muscle lengthens under load. This increased mechanical demand can exceed the tissue’s limited tolerance during the inflammatory and proliferative phases, leading to pain, swelling, microtrauma, or a delay in healing. Keep loading light and controlled until there are no adverse tissue effects and the tissue’s tolerance has improved; only then can structured eccentric work be introduced to promote remodeling. Concentric contractions and broader isotonic or higher-load approaches are generally safer to initiate earlier, with eccentric work reserved for later stages when the tissue can handle it.
Question 4
Taking equal to or more than how many medications increases fall risk?
Correct Answer:
4
Explanation:
Polypharmacy raises fall risk because the chance of adverse drug effects, drug interactions, and sedating or blood pressure–altering effects grows as more medicines are taken. Reaching four medications often marks a tipping point where these cumulative effects become noticeable, increasing dizziness, orthostatic hypotension, confusion, or slowed reaction time—all factors that can lead to a fall. So four or more medications is a threshold where the risk is meaningfully higher than with fewer medications. In practice, review and simplify medications when possible, especially avoiding combinations with strong sedative or hypotensive effects, to reduce fall risk.
Question 5
Phasic, fast-twitch muscle fibers correspond to which type?
Correct Answer:
Type II
Explanation:
Phasic, fast-twitch fibers are built for rapid, powerful contractions and fatigue quickly. This maps to the fast-twitch category, known as Type II. Type I fibers are slow-twitch and support sustained, endurance activities. Within the fast-twitch group are IIa and IIx, with IIa being fast-oxidative-glycolytic (somewhat more fatigue-resistant) and IIx being fast-glycolytic (fatigue the quickest). So, the best match for phasic, fast-twitch is Type II, since it covers the fast-twitch fiber family.
