MULTIPLE CHOICE

 

1. Which is a serious adverse effect of decongestants?

A.	Hypotension
B.	Hypertension
C.	Orbital edema
D.	Facial flushing

 

 

ANS:   B

 

	Feedback
A	Alpha receptor stimulation does not cause hypotension.
B	Sympathomimetic decongestants cause stimulation of the alpha-adrenergic receptors that can increase blood pressure. Excessive use of decongestants when taking a beta-adrenergic blocking agent or monoamine oxidase inhibitor can cause significant hypertension.
C	Alpha receptor stimulation does not cause orbital edema.
D	Alpha receptor stimulation does not cause facial flushing.

2. The nurse is teaching a patient about the administration of antihistamines. The nurse will instruct the patient to take the medication at what time of day?

A.	PRN throughout the day
B.	After contact with an allergen
C.	45 minutes before exposure to an allergen
D.	Once nasal congestion begins

 

 

ANS:   C

 

	Feedback
A	PRN use of antihistamines is not the most effective administration.
B	Waiting until after contact with an allergen is not the most effective administration of antihistamines.
C	Allergies may be seasonal or perennial. People are commonly allergic to more than one antigen simultaneously, so seasons may overlap or occur more than once per year. Antihistamines do not prevent histamine release, but reduce the symptoms of an allergic reaction by competing with the histamines for receptor sites. Antihistamines are most effective when taken 45 to 60 minutes before anticipated exposure to the allergen or when symptoms first appear.
D	Waiting until nasal congestion begins is not the most effective administration of antihistamines.

3. What can result if a patient overuses topical decongestants?

A.	Hypertensive crisis
B.	Allergic reaction
C.	Secondary congestion
D.	Permanent olfactory damage

 

 

ANS:   C

 

	Feedback
A	Although decongestants can cause elevated blood pressure, they are not likely to cause hypertensive crisis.
B	Allergic reaction is unlikely with decongestants.
C	Overuse of topical decongestants may lead to a rebound or increase in nasal secretions causing a secondary congestion (known as rhinitis medicamentosa). This secondary congestion is thought to be caused by excessive vasoconstriction of blood vessels and direct irritation of the mucous membranes by the medication. As vasoconstriction wears off, the irritation triggers excessive blood flow to the passages, which in turn causes swelling and engorgement to reappear in greater intensity.
D	Damage to nasal tissues resulting from the use of decongestants is unlikely to be permanent.

4. A patient at sports camp is complaining of itchy, watery eyes, coughing, and sneezing when outdoors. The patient’s chart states that he has an allergy to grasses. Which medication will the nurse administer?

A.	Antitussive
B.	Expectorant
C.	Antihistamine
D.	Decongestant

 

 

ANS:   C

 

	Feedback
A	Antitussive medications are for relief of cough.
B	Expectorants are for the loosening of mucus so the patient can expel it by coughing.
C	Antihistamines are used for inflammation and swelling secondary to the release of histamine during an antigen-antibody reaction. A grass allergy means that the patient experiences a release of histamine (antibody reaction) when exposed to the antigen, grass.
D	Decongestants would not help these symptoms as much as antihistamines.
