A nurse is assessing patient response to medications received. Which must the nurse know about these drugs to best evaluate whether the expected outcomes of the drug therapy have been achieved?
Therapeutic effects
Chemical composition
Mechanism of actions
Side effects
The Correct Answer is A
Choice A reason: Therapeutic effects define expected outcomes; knowing these (e.g., pain relief) lets the nurse assess if the drug meets its clinical goal effectively.
Choice B reason: Chemical composition informs structure, not outcome; it’s irrelevant to evaluating if the drug achieves its intended physiological effect directly.
Choice C reason: Mechanism explains how drugs work; it’s useful but secondary to knowing the actual therapeutic result needed for outcome assessment.
Choice D reason: Side effects monitor safety, not efficacy; they don’t directly measure if the drug achieves its primary therapeutic purpose as intended.

Correct Answer is A
Explanation
Choice A reason: Flow rate is volume divided by time; 250 mL over 4 hours equals 62.5 mL/hr, ensuring safe transfusion pacing to avoid fluid overload or hemolysis.
Choice B reason: 125 mL/hr assumes 250 mL over 2 hours; this doubles the ordered rate, risking circulatory overload and transfusion reactions in a standard protocol.
Choice C reason: 250 mL/hr infuses the unit in 1 hour; this rapid rate exceeds safe limits, potentially causing hypertension or pulmonary edema in vulnerable patients.
Choice D reason: 500 mL/hr is far too fast, implying 250 mL in 30 minutes; this dangerous speed could trigger severe hemolytic reactions or cardiovascular collapse.
Correct Answer is D
Explanation
Choice A reason: Moderate reactions don't cause breathing difficulty or hypotension. Severe symptoms indicate anaphylaxis, requiring emergency intervention.
Choice B reason: Symptoms align with anaphylaxis, not food poisoning. Assuming an unrelated cause delays life-saving treatment.
Choice C reason: Mild reactions lack systemic effects like hypotension and breathing difficulties. Antihistamines alone are insufficient for anaphylaxis.
Choice D reason: Anaphylaxis involves systemic reactions such as hypotension, airway constriction, and skin symptoms. Immediate interventions prevent progression and save lives.
