You note that “peanut allergy” is listed on the child’s health record. Knowing that he participated in the trading of lunch items, which of the following do you suspect caused the allergic reaction?
A. Apple
B. Ham sandwich
C. Cookies
D. Celery
C Cookies are the only item that could contain peanuts
You volunteer as a summer day camp nurse for your local community organization. Children bring their own lunches and like to trade items. During one such lunch time a parent volunteer comes running to tell you that one of the six year olds is having trouble breathing. You find the child bent over, crying and taking deep rapid breaths. You also hear audible wheezing and the child tells you he is having trouble breathing.
What is happening?
What led you to this conclusion?
He is having an allergic reaction.
Deep, rapid breathing
Wheezing
Shortness of breath
What do you anticipate will be the treatment for this?
What does it do?
How is it given?
Epinephrine
Classificationi: Adrenergic
Therapeutic Class: antiasthmatic, bronchodilator, vasopressor
Stimulates both beta 1 and beta 2 adrenergic receptors, produces bronchodilation
Stimulates alpha adrenergic agonist properties which result in vasoconstriction
Inhibits the release of mediators of immediate hypersensitivity reactions from mast cells
Therapeutic effects: bronchodilation, maintenance of heart rate and BP,
You are caring for an 82 year old man who has a diagnosis of heart failure, COPD, and hypertension. He is on a number of medications and has a new order for labetalol (Trandate) 200 mg, po, daily. You are going to teach him about his new medication.
He is concerned about the dosage of this new medication. He said his BP med was only 12.5 mg before.
How will you address this concern?
He was probably on a different medication. You can discuss with the patient why the medication was changed (did he ask for a change or did doc want it)
Verify that this is the correct medication before giving it. ALWAYS listen to the patient.
Which of the following signs/symptoms should he report while taking labetalol (Trandate)? Select all that apply
A. Dizziness B. Shortness of breath C. Heartburn D. Weight loss of 3 to 5 pounds E. Swollen ankles
A, B, E
Affects heart and lungs. May be decreasing cardiac output leading to dizziness and swollen ankles. Bronchoconstriction may be leading to SOB.
You are caring for an 89 year old woman scheduled for removal of a R eye cataract.
Home meds: Lanoxin 0.25 mg po daily, Thyroid 30 mg po daily, Sinequan 50 mg po HS, and Tylenol ES po q4 hrs prn pain.

Which classification do each of these drugs fall under?
Anticholinergic
Cholinergic
Adrenergic
Antibiotic
Phenylphrine: Adrenergic
Homatropine: Anticholinergic
Garamycin: Antibiotic
Assign each of the following features to either Phenylephrine or Homatropine:
Cholinergic blocking drug Stimulates alpha-adrenergic Can cause hypertension Blocks the muscarinic receptor site Dilates the pupil of the eye Stimulates the sympathetic system
I don’t understand.
Check the slide.
Adrenergic Stimulates alpha-adrenergic Stimulates the sympathetic system Causes vasoconstriction (can cause HTN) What pre-op eye medication is this?
Phenylephrine
Anticholinergic Cholinergic blocking drug Blocks the muscarinic receptor site Dilates the pupil of the eye What pre-op eye medication is this?
Homatropine
