Question

what is the weight interval of the grooves on a standard physician office scale?

10 lbs
25 lbs
50 lbs
100 lbs

Explanation:

Identify the scale components

Using the Clinical Assessment and Weight Monitoring knowledge points, we analyze a standard physician office scale (triple-beam balance). The lower heavy beam has notched grooves where the large poise weight rests.

Determine the groove intervals

On a standard mechanical physician scale, the lower beam measures weight in large increments. These notched grooves are spaced at intervals of exactly \(50\text{ lbs}\).

Analyze the upper beam

The upper beam is used for fine-tuning the measurement. It has smaller, sliding increments typically marked in quarter-pound or single-pound divisions up to \(50\text{ lbs}\).

Match with options

The question asks for the interval of the grooves (notches) on the main beam. This corresponds to the \(50\text{ lbs}\) increments.

Answer:

• (A) 10 lbs
• (B) 25 lbs
• (C) 50 lbs (Correct answer)
• (D) 100 lbs
