What assessment finding indicates to the nurse that timolol (Timoptic) has been effective?

A) The patient's blood pressure increases.
B) The patient's intraocular pressure is reduced.
C) The patient's pulse is reduced.
D) The patient's angina is reduced.

Question 2

Several processes enable a drug to reach a specific concentration in the body. Together they are called dynamic equilibrium. What are these processes? (Select all that apply.)

A) Distribution to the active site
B) Biotransformation
C) Absorption from the muscle
D) Excretion
E) Interaction with other drugs

Answer to Question 1

B
Feedback:
Timolol and carteolol are available in an ophthalmic form of the drug for reduction of intraocular pressure in patients with open-angle glaucoma. A decrease in intraocular pressure would indicate it has been effective. Timolol can also be used to treat hypertension but an increase in blood pressure would indicate the drug was not effective. Reduced pulse rate and reduced angina would not be related to this drug, especially if it was given in ophthalmic form when very little of the drug is absorbed systemically.

Answer to Question 2

A, B, D
Feedback:
The actual concentration that a drug reaches in the body results from a dynamic equilibrium involving several processes: Absorption from the site of entry (can be from the muscle, the gastrointestinal (GI) tract if taken orally, of the subcutaneous tissue if given by that route); Distribution to the active site; biotransformation (metabolism) in the liver; excretion from the body. Interaction with other drugs is not part of the dynamic equilibrium.
