.
- 1.
Which of the following happens during a Hypersensitivity Type I reaction? (Select all that apply)
- A.
Production of antibodies in response to an allergen (typically IgE as a mediator)
- B.
Mast Cell activation as a result of response to an allergen leads to histamine release
- C.
Systemic reaction or localized reaction to specific tissue or organ
- D.
Vasodilation, smooth muscle spasm/contraction, increased membrane permeability (aka - anaphylaxis)
- E.
Excessive mucous production and forceful coughing due to dermatitis
Correct Answer(s)
A. Production of antibodies in response to an allergen (typically IgE as a mediator)
B. Mast Cell activation as a result of response to an allergen leads to histamine release
C. Systemic reaction or localized reaction to specific tissue or organ
D. Vasodilation, smooth muscle spasm/contraction, increased membrane permeability (aka - anaphylaxis)Explanation
During a Hypersensitivity Type I reaction, the body produces antibodies, typically IgE, in response to an allergen. This leads to the activation of mast cells, which release histamine. This histamine release causes vasodilation, smooth muscle spasm/contraction, and increased membrane permeability, resulting in a systemic or localized reaction in specific tissues or organs. Excessive mucous production and forceful coughing due to dermatitis are not associated with a Hypersensitivity Type I reaction.Rate this question:

Correct Answer(s)
A. Client's name
B. Date/time of order
C. Medication name
E. Medication Dosage
F. Administration Route
G. Timing and frequency
H. Parameters/Indications
J. Signature of provider ordering medicationExplanation
Medication orders typically include the client's name, date/time of the order, medication name, medication dosage, administration route, timing and frequency, parameters/indications, and the signature of the provider ordering the medication. These elements are necessary for ensuring accurate and safe medication administration. The client's name is needed to ensure that the medication is intended for the correct individual. The date/time of the order is important for tracking when the medication was prescribed. The medication name, dosage, administration route, timing and frequency, and parameters/indications provide specific instructions for the medication administration. The signature of the provider ordering the medication is necessary for accountability and legal purposes.Rate this question:

An additive drug effect:
- A.
Happens when 1 + 1 = 1
- B.
Happens when 1 + 1 = 3
- C.
Happens when 1 + 1 = 2
- D.
Happens when 1 + 1 = -1
Correct Answer
C. Happens when 1 + 1 = 2Explanation
An additive drug effect happens when 1 Drug + 1 Drug = 2 Drug effects in 1
Synergism and poteniation is when 1 Drug + 1 Drug = 3 Drug effects in 1 (Oxycodone and Tylenol are often given together because they both make the other work better 1 + 1 = 3)Rate this question:

The requirement for multiple doses to be used to reach an otherwise therapeutic level of care for a patient
Correct Answer
B. The concurrent use of multiple medications that are often medically unnecessaryExplanation
Poly-pharmacy describes the concurrent use of multiple medications that are often medically unnecessary. Current data indicates that upwards of 40% of elderly patients living in their own homes and 21% of adults with intellectual disability are experiencing poly-pharmacy.Rate this question:

Drug to drug interactions increase by:
- A.
20% for 2 drugs and ~90% for 5 drugs
- B.
80% for 3 drugs and ~100% for 6 drugs
- C.
12% for 2 drugs and ~26% for 5 drugs
- D.
38% for 3 drugs and ~62% for 6 drugs
Correct Answer
A. 20% for 2 drugs and ~90% for 5 drugsExplanation
The given answer states that the drug to drug interactions increase by 20% for 2 drugs and approximately 90% for 5 drugs. This means that when two drugs are taken together, there is a 20% increase in the likelihood of interactions occurring. Similarly, when five drugs are taken together, the likelihood of interactions increases by approximately 90%. This suggests that the more drugs are taken simultaneously, the higher the risk of potential interactions between them.Rate this question:

Which of the following are provider concerns related to OTC Medications?
- A.
Unclear Ingredients
- B.
Manufacturer Reputation
- C.
Cost
- D.

- E.
Overdose risk
- F.
Risk of drug-drug interactions
- G.

Correct Answer(s)
A. Unclear Ingredients
D. Self-diagnosis & treatment
E. Overdose risk
F. Risk of drug-drug interactionsExplanation
Provider concerns related to OTC medications include unclear ingredients, self-diagnosis and treatment, overdose risk, and risk of drug-drug interactions. Providers may be concerned about the lack of transparency regarding the ingredients in OTC medications, as this can affect their ability to effectively treat their patients. They may also be concerned about patients self-diagnosing and treating their conditions without proper medical guidance, which can lead to incorrect treatment and potential harm. Providers are also mindful of the risk of overdose with OTC medications, as patients may not always follow dosage instructions correctly. Additionally, providers are concerned about the potential for drug-drug interactions when patients take multiple OTC medications simultaneously, which can have adverse effects.Rate this question:

A ________ reaction happens when ultraviolet exposure changes the structure of the drug so that it is seen by the body's immune system as an invader. The allergic response causes inflammation of the skin in the sun-exposed areas.
Correct Answer
photoallergic, photoallergyExplanation
A photoallergic reaction occurs when ultraviolet exposure alters the chemical structure of a drug, causing the body's immune system to recognize it as a foreign substance. This recognition triggers an allergic response, leading to inflammation of the skin in areas exposed to the sun. The terms "photoallergic" and "photoallergy" are used to describe this specific type of allergic reaction caused by sunlight.Rate this question:

________ are unintended pharmacologic effects that occur when a medication is administered correctly, while a ________ is a secondary unwanted effect that occurs due to drug therapy
Correct Answer
Adverse reaction, adverse event, adverse reactions, adverse events, adverse drug reaction, adverse drug reactions
side effectExplanation
An adverse reaction is never intended whereas a side effect can sometimes be desired.
E.g. If diphenhydramine were used to treat an allergic reaction, and a person experienced dyspnea (difficulty breathing) and lethargy (drowsiness), the adverse event would be respiratory distress whereas a side effect would be drowsiness.Rate this question:
