QUESTIONS WITH VERIFIED ANSWERS
What is the difference between type 1 allergic rash and morbilliform rash? -
| | | | | | | | | | | |
correct-answer--type 1 allergic rash--hives, wheals, itchy, type 1 hypersensitivity
| | | | | | | | |
-morbilliform rash--most likely due to a drug reaction, looks like the measles,
| | | | | | | | | | |
|"drug eruption", type IV delayed hypersensitivity
| | | | |
What is a type 2 hypersensitivity? - correct-answer--IgG or IgM mediated
| | | | | | | | | |
-Ex: heparin induced thrombocytopenia
| | |
-will resolve when the drug is stopped
| | | | | |
What is type 3 hypersensitivity? - correct-answer--Immune complex mediated
| | | | | | | |
-Ex: serum sickness
| |
-will resolve when the drug is stopped
| | | | | |
What is type 4 hypersensitivity? - correct-answer--Cell mediated (cytotoxic t cells)
| | | | | | | | | |
-delayed response |
,2 || |P |a |g |e
-diffuse, bilateral, symmetrical | |
-Ex: drug rash, contact dermatitis, steven-johnson syndrome
| | | | | |
What is a pseudo allergy? - correct-answer--mast cell degranulation by a non-IgE
| | | | | | | | | | |
mediated mechanism
| |
-Ex: opiate analgesic causes direct mast cell activation--causing itching
| | | | | | | |
What does the QT interval represent? - correct-answer-ventricular depolarization
| | | | | | | |
and repolarization
| |
A longer QT interval increases the risk of what? - correct-answer--ventricular
| | | | | | | | | |
dysrhythmias (particularly Torsades de pointe)
| | | | |
-sudden cardiac death | |
Who is at an increased risk of a long QT interval? - correct-answer--females
| | | | | | | | | | | |
-electrolyte imbalances (hypokalemia, hypomagnesemia, hypocalcemia)
| | | |
-renal or hepatic problems
| | |
-taking multiple drugs that can prolong QT interval
| | | | | | |
-grapefruit juice that might inhibit metabolism of drugs that prolong QT interval
| | | | | | | | | | |
-diuretic use (reduces electrolytes)| | |
,3 || |P |a |g |e
-bradycardia
-underlying cardiac disease | |
-digitalis therapy |
-family history of long QT syndrome
| | | | |
-congenital long QT syndrome | | |
What factors can impact pharmacokinetics, pharmacodynamics, drug efficacy and
| | | | | | | |
likelihood of drug reactions? - correct-answer--age, sex, weight, genetics, diet, co-
| | | | | | | | | | |
existing diseases, etc.
| | |
Why are pharmaceutical companies less likely to research children? - correct-
| | | | | | | | | |
answer--ethical risks
| |
-health risks |
-cost
Why are infants at a higher risk of adverse effects from drugs? - correct-answer--
| | | | | | | | | | | | |
organ immaturity
| |
-under-developed blood brain barrier | | |
-variable peristalsis |
-variable blood flow to muscles
| | | |
-increased total % body water (affects distribution)
| | | | | |
, 4 || |P |a |g |e
-reduced metabolism |
What is polypharmacy? - correct-answer-use of multiple medications
| | | | | | |
Number of drug reactions is closely related to number of drugs a person is taking.
| | | | | | | | | | | | | |
True or false? - correct-answer-True
| | | | |
What are some prescribing issues with the elderly? - correct-answer--
| | | | | | | | |
polypharmacy
|
-disease-drug reactions (Ex: cirrhosis and tylenol) | | | | |
-physiologic changes (Ex: renal & hepatic dysfunction)
| | | | | |
-multiple prescriptions from different specialities
| | | |
-poor adherence |
What is the Beers criteria? - correct-answer--lists potentially inappropriate drugs
| | | | | | | | |
that lead to adverse effects in the elderly
| | | | | | | |
-particularly in those greater than 65 years old | | | | | | |
-not applicable to those in hospice or palliative care
| | | | | | | |
-a tool not a guideline--must use your own clinical judgment
