What term describes a severe, life-threatening allergic reaction to a medication?
Local reaction
Anaphylaxis
Inflammation
Sensitivity
The Correct Answer is B
A. Local reaction: A local reaction is limited to a small area, such as redness, swelling, or itching at the injection site. It is not systemic or life-threatening and does not compromise airway, circulation, or organ function.
B. Anaphylaxis: Anaphylaxis is a severe, systemic, IgE-mediated allergic reaction that can rapidly involve multiple organ systems, including respiratory distress, hypotension, and cardiovascular collapse. Immediate recognition and treatment with epinephrine and supportive care are critical to prevent death.
C. Inflammation: Inflammation is a nonspecific immune response characterized by redness, swelling, heat, pain, and loss of function. It can occur in response to infection, injury, or irritation, but it is not inherently life-threatening.
D. Sensitivity: Sensitivity refers to an exaggerated immune response to a substance, which may cause mild to moderate symptoms such as rash or itching. It does not describe the acute, life-threatening systemic reaction seen in anaphylaxis.

Correct Answer is C
Explanation
Calculation:
- Identify the total volume and infusion time
Total Volume: 500 mL
Infusion Time: 4 hours
- Calculate the infusion rate
Infusion Rate (mL/hr) = Total Volume ÷ Time
Infusion Rate = 500 ÷ 4
= 125 mL/hr
Correct Answer is ["B","C","E"]
Explanation
A. Crushing all tablets for faster absorption: Not all tablets are safe to crush; enteric-coated or extended-release formulations can lose their therapeutic effect or cause toxicity if altered. Crushing indiscriminately increases the risk of medication errors and adverse effects.
B. Using current weight for weight-based dosages: Accurate, up-to-date weight is essential for calculating pediatric or weight-dependent medication dosages. Using outdated or estimated weights can lead to underdosing or overdosing, making this a key safety measure.
C. Documenting immediately after administration: Timely documentation ensures accurate tracking of medications given and prevents double dosing or omissions. Immediate recording supports communication among the healthcare team and reduces administration errors.
D. Administering medications without clarifying illegible orders: Giving medications without clarification is a major safety risk. Misreading an order can result in wrong drug, dose, route, or timing errors. Clarification with the prescriber is mandatory.
E. Comparing the medication label with the MAR: Verifying the medication against the MAR before administration ensures the right drug, dose, route, and time are given. This “five rights” check is a primary strategy to prevent errors during administration.
