While testing muscle strength "movement but not against gravity" is given:

Appeared in: IGNOU PB Bsc Nsg.Entrance-2026

Explanation

  • The Medical Research Council (MRC) scale is a standard tool for grading muscle power on a 0-5 scale.
  • A score of Grade 2 signifies that the muscle can perform a full range of motion, but only when the force of gravity is removed or neutralized.
  • The phrase 'movement but not against gravity' directly corresponds to the definition of Grade 2 muscle strength, which is also described as 'movement with gravity eliminated'.

Why Other Options Were Wrong

  • Option A: Grade 1 indicates only a flicker or trace of muscle contraction is visible or palpable, with no actual movement at the joint.
  • Option C: Grade 3 indicates the muscle is strong enough to move the limb against the force of gravity through the full range of motion, but not against any additional resistance.
  • Option D: Grade 4 indicates movement against gravity plus some or moderate resistance. This is a higher level of function than described.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Interpretation of the Medical Research Council (MRC) scale for muscle strength as background academic context rather than a clinical decision trigger.
  • Accurate muscle strength assessment is crucial for diagnosing neurological conditions, tracking disease progression (like in Guillain-Barré syndrome or muscular dystrophy), and evaluating recovery after injury or stroke.
  • Nurses frequently use this scale to monitor a patient's functional status, communicate changes to the healthcare team, and plan appropriate mobility assistance and safety precautions (e.g., fall risk).
  • What if? If the patient could only produce a flicker of contraction in their quadriceps muscle but could not move their leg at all, the grade would be 1, not 2. This would indicate a more severe weakness and might necessitate different interventions, such as passive range-of-motion exercises to prevent contractures.
How to Approach the Question
  • First, identify the key descriptive phrase in the question: 'movement but not against gravity'.
  • Recall the standard scale used for muscle strength testing, which is the Medical Research Council (MRC) scale, graded from 0 to 5.
  • Mentally review the definitions for each grade on the MRC scale.
  • Match the key phrase 'movement but not against gravity' to its corresponding grade. This is the definition for Grade 2 (also described as 'movement with gravity eliminated').
  • Select the option that corresponds to Grade 2.
Concept Tested & Keywords
