Q

True or False:
Sublingual and Buccal administration drugs have to consider the First-Pass effect when considering dosage.

A

False:
Sublingual and Buccal ARE Enteral administration methods, but they are dissolved and absorbed into the blood stream in the mouth. Because of this they bypass the first-pass effect

26
Q

What is the First-Pass effect?

An inactivation of a drug by being processed in the liver.

27
Q

True or False: Installations and Irrigations are subcategories of the Topical route of drug administration

30
Q

A drug that is applied to the mucosa of the respiratory tract is labeled as what subcategory of the Topical route?

A

An Inhalant/Inhalation

31
Q

True or False:
Topicals are absorbed slowly, which leads to fewer side effects.

A

True:
Topicals are absorbed slowly

32
Q

Do Transdermal patches bypass the First-Pass effect? Why or why not?

A

Yes, because they are absorbed into the dermis and circulate into the blood. They are not metabolized by the liver.

33
Q

What does a Clonidine patch do?

A

A Clonidine patch lowers a patient’s blood pressure.

34
Q

A patient has gotten into a car crash and is brought into the E.R. The Nurse notices that the patient has a Clonidine patch? How should the nurse handle the Clonidine patch?

A

Remove the patch.
Clonidine patches lower a patient’s blood pressure. The Patient was just in a car crash, and we don’t want their Bp getting any lower.

35
Q

Where in the body is an Opthalmic administration given?

A

The eyes

36
Q

When giving a single medication via the Opthalmic route, how long should you wait in-between eye drops?
What about for two separate medications?

A

-For single Medications: 2 min between drops

Otic is into the ear.

38
Q

To shrink swollen mucous membranes inside of the nose

39
Q

Following the primary reason for Nasal administration (shrink swollen mucous membranes), what is another reason one might administer a Nasal medication?

44
Q

What technique does the Parenteral administration route require use of?

A

The Aseptic Technique

45
Q
