After assessing a client's muscle functionality, the nurse assigns a Lovett scale grade of F. Which statement best describes the muscle functionality?

• A. Full Range of Motion with Gravity
• B. No Contraction
• C. Movement with Gravity Eliminated
• D. Full Strength Against Resistance

Answer: (A)

The main idea is how the Lovett scale describes muscle strength based on range of motion and the effect of gravity. An F grade means the muscle can move through its full range of motion while gravity acts on the limb, indicating normal strength for that action. This is the best match because it describes full ROM with gravity present, which is what the grade conveys. In contrast, no contraction means there’s no movement at all; movement only when gravity is eliminated indicates a weaker grade; and full strength against resistance describes the highest level of strength beyond what’s needed for ordinary movement with gravity. So the statement that fits the grade is having a full range of motion against gravity.
