Handout
Name________________
Date ________________
Directions: Use this handout to test your understanding of the respiratory system’s
control of breathing. If the situation is closely related to the NEURAL factors affecting
respiration, write an “N” in the blank provided. If the situation is more closely related to
the CHEMICAL factors, write a “C” in the blank.

Donnie jumps in a pool of cold water and “gasps” for air.
Maria is “out of breath” after running up four flights of stairs.
Emanuel, a health care assistant, determines the respiratory rate of his
patient, Mr. Nguyen, to be 10 breaths per minute. Emanuel learns that his
patient is on Morphine for post-operative pain.

constantly sneezes.
Terrell has been taking diet pills and has experienced an increase in
respiratory rate.
Directions: Read each of the following questions. Use your own words to respond the
questions.

2.06 Prototype Assessment Items
Note: These items illustrate the types of items used in the item bank for this objective.
All items have been written to match the cognitive process of the understand verb in the
objective. Questions require students to interpret, summarize or explain safety
procedures. These exact questions will not be used on the secured test, but questions
in similar formats will be used.
These assessment items may be used as prototypes by teachers and students to
generate similar items to comprise formative assessments for you classroom. This
strategy is especially helpful during the field test year when classroom item banks are
not available. Results of formative assessment should be used to diagnose levels of
mastery, determine if re-teaching is needed, and guide further instruction.
