Nasal Anatomy & Physiology Quiz

What is the primary function of the nasal mucosa in drug delivery?

• Secretes digestive enzymes

• Traps oxygen molecules

• Aids in drug absorption due to rich blood supply

• Produces insulin

Which of the following structures produces mucus for nasal hydration?

• Nasolacrimal duct

• Olfactory bulb

• Paranasal sinuses

• Pituitary gland

The nasal cavity warms and humidifies the air due to:

• Enzyme production

• Rich vascularization

• Sweat glands

• Adrenal function

The ciliated epithelium and goblet cells in the nose primarily help with:

• Absorbing nutrients

• Degrading drugs

• Filtering dust and microbes

• Activating olfactory nerves

Nasal administration offers the following advantage EXCEPT:

• Rapid onset

• Protection against microbial infections

• Avoidance of first-pass metabolism

• Needle-free convenience

Which condition is most suitable for nasal antihistamines?

• Allergic rhinitis

• Hypertension

• Diabetes

• Tuberculosis

Decongestants should not be used for more than 3 days to avoid:

• Liver toxicity

• Rebound congestion

• Hypoglycemia

• Hypertension

One systemic condition that may benefit from nasal administration is:

• Constipation

• Asthma

• Eczema

• Arthritis

Which of the following is NOT an advantage of nasal drug delivery?

• Rapid local effect

• Systemic absorption

• High-dose tolerance

• Needle-free administration

Why are lower drug doses often effective via nasal administration?

• Poor blood supply

• High pH environment

• Direct delivery to target site

• Enhanced hepatic metabolism
