1. ID injection is injected into the dermis. Commonly used for?
IV therapy
Skin testing
Stimulization
Vaccines
2. Describe the significance of idiosyncratic reactions in pharmacology and
their implications for patient care.
Idiosyncratic reactions are always severe and require immediate
hospitalization.
Idiosyncratic reactions are significant because they can lead to
unexpected adverse effects that require careful monitoring and
individualized patient care.
Idiosyncratic reactions are irrelevant to patient care and can be
ignored.
Idiosyncratic reactions are common and predictable, making them
easy to manage.
3. What is a hypersensitivity reaction?
An unpredictable reaction that cannot be explained by the known
mechanisms of action of the drug
A reaction that occurs when food in the digestive tract alters the
absorption or metabolism of medications.
An unpredictable reaction to a drug that may have an immediate
reaction due to anaphylaxis or delayed reaction due to preexisting
, medical conditions.
A reaction between two (or more) drugs
4. What is the primary focus of pharmacology?
The study of drugs and their effects on the body.
The study of medical ethics.
The study of human anatomy.
The study of disease prevention.
5. Describe why the first trimester is particularly critical for fetal development in
relation to drug exposure.
The first trimester has no impact on fetal development.
The first trimester is less critical as the fetus is not yet formed.
The first trimester is critical because major organ systems are
developing, making the fetus more susceptible to teratogenic
effects of drugs.
The first trimester is when the mother is least likely to take
medications.
6. If a patient is prescribed two medications that are known to have a significant
drug-drug interaction, what should a nurse do?
The nurse should wait for the patient to report any side effects before
taking action.
The nurse should consult with the healthcare provider to discuss
alternative medications or adjust dosages.
The nurse should administer both medications without any changes.
, The nurse should inform the patient that drug-drug interactions are
not a concern.

5-6 hours
1-5 hours
4-8 hours
1-2 hours
9. If a patient is prescribed a medication with a short half-life, what
considerations should a nurse take into account for patient education?
The nurse should advise the patient to take the medication only when
symptoms worsen.
The nurse should tell the patient that the medication can be taken at
any time.
The nurse should educate the patient on the importance of
adhering to the prescribed schedule for taking the medication.
The nurse should inform the patient that they can skip doses if they
feel better.
10. Describe the importance of pharmacokinetics in medication administration.
, Pharmacokinetics focuses solely on drug interactions.
Pharmacokinetics only concerns the classification of drugs.
Pharmacokinetics is irrelevant to patient education.
Pharmacokinetics is important because it helps determine the
appropriate dosage and timing of medication to achieve the
desired therapeutic effect.
11. Describe the significance of understanding adverse reactions in
pharmacology for patient safety.
Adverse reactions are solely the responsibility of the pharmacist.
Adverse reactions only affect the efficacy of the drug.
Adverse reactions are not significant as they are rare occurrences.
Understanding adverse reactions is crucial for ensuring patient
safety and effective medication management.
12. Describe the role of Metformin in the management of diabetes.
Metformin is primarily used for weight loss in non-diabetic patients.
Metformin is used to increase insulin production in Type 1 diabetes.
Metformin helps to lower blood sugar levels in individuals with
Type 2 diabetes by improving insulin sensitivity.
Metformin is a type of insulin therapy for all diabetes types.
13. If a patient is prescribed a Schedule II drug, what specific considerations
should a nurse keep in mind regarding patient education?
The nurse should encourage the patient to share the medication with
