Which of the following would be considered an adverse effect?
unintended and undesired effects of the drug
mild stomach upset
expected changes that occur to the drug inside the body
desired effect of the drug
The Correct Answer is A
A. Unintended and undesired effects of the drug.: An adverse effect refers to any harmful, unintended, and undesired reaction to a medication that occurs at normal doses used for prevention, diagnosis, or treatment.
B. Mild stomach upset.: A mild stomach upset may be considered a side effect rather than an adverse effect if it is expected and does not pose a health risk. Side effects are generally predictable, dose-related, and less severe compared to true adverse reactions.
C. Expected changes that occur to the drug inside the body.: This describes pharmacokinetics, the process of absorption, distribution, metabolism, and excretion of drugs. It is not related to drug effects on the body but rather how the body handles the medication.
D. Desired effect of the drug.: The desired effect is the therapeutic outcome or intended action of the medication, such as pain relief or infection control. It represents the beneficial, goal-oriented response, not an adverse or unintended reaction.

Correct Answer is C
Explanation
A. A tablet given orally.: Oral administration is considered an enteral route because the drug passes through the gastrointestinal tract for absorption. It is convenient and noninvasive but not classified as parenteral since it does not involve injection.
B. A tablet given sublingually.: The sublingual route allows for rapid absorption through the mucous membranes under the tongue, bypassing first-pass metabolism. However, it is still classified as an enteral route because it involves absorption through the alimentary canal.
C. A subcutaneous injection.: Parenteral administration involves delivering medication by injection through the skin or directly into body tissues. A subcutaneous injection is a parenteral route because it bypasses the gastrointestinal tract and allows for rapid systemic absorption.
D. A liquid medication given orally.: Like oral tablets, oral liquids are administered enterally because they enter the digestive system for absorption. They are suitable for clients who have difficulty swallowing but do not qualify as parenteral medications.
Correct Answer is A
Explanation
A. SR.: SR stands for “sustained release” and is an accepted, clear abbreviation used to describe the medication’s formulation. It is not considered error-prone because it has a standardized meaning in pharmacology and does not cause confusion in prescribing or administration.
B. DC.: “DC” can be misinterpreted as “discontinue” or “discharge,” leading to potential medication errors if the order is unclear. The Joint Commission lists it as an error-prone abbreviation and recommends using full words to avoid ambiguity.
C. QD.: “QD,” meaning “once daily,” is on the list of error-prone abbreviations because it can easily be mistaken for “QID” (four times daily). To ensure clarity, prescribers should write “daily” instead of using this abbreviation.
D. HS.: “HS” can be misread as “half strength” or “hour of sleep,” which may result in incorrect dosing or timing. Writing out “at bedtime” or “half strength” is recommended to prevent misinterpretation.
