A nurse is providing health education about the way the normal intraocular pressure (IOP) is maintained. The nurse should explain that normal IOP results from which of the following?

A) Consistent production and resorption of tears
B) Consistent feedback from baroreceptors located throughout the retina
C) A balance between production and drainage of aqueous humor
D) Two-way interaction between the medulla oblongata and the eye

Question 2

A female patient has been diagnosed with tuberculosis and begun multiple-drug therapy. The woman has asked the nurse why it is necessary for her to take several different drugs instead of one single drug.

How should the nurse best respond to the patient's question? A) Multiple drugs are used because doctors aren't sure which drug will kill a particular TB strain.
B) The use of multiple drugs prevents the development of drug-resistant TB.
C) Multiple drugs are prescribed because the final testing results for TB can take up to 3 months.
D) Multiple drugs are used in order to speed up the course of treatment.

Answer to Question 1

C
Feedback:
Normally, production and drainage of aqueous humor are approximately equal, and the intraocular pressure (IOP) is normal. IOP is not dependent of tear production, baroreceptors in the eye, or stimulation from the medulla.

Answer to Question 2

B
Feedback:
Use of multiple drugs to treat TB is necessary to prevent the development of drug-resistant TB. This approach to treatment is not necessitated by delays in testing, questionable diagnostic results, or the need to hasten the course of treatment.
