The most critical of the following areas to assess prior to medication administration is the client's:
Surgical history.
Drug tolerance.
Diet history.
Allergy history.
The Correct Answer is D
Choice A rationale
Surgical history provides context regarding past medical interventions and potential anatomical alterations. While relevant for comprehensive patient assessment, it does not directly impact the immediate safety of medication administration in the same critical manner as identifying drug hypersensitivities, which can precipitate life-threatening anaphylactic reactions.
Choice B rationale
Drug tolerance refers to a diminished physiological response to a medication over time, requiring increased doses to achieve the same effect. While important for therapeutic efficacy and dose adjustment, it is secondary to the immediate danger posed by an allergic reaction, which can be acute and severe.
Choice C rationale
Diet history is crucial for identifying potential drug-food interactions or nutritional deficiencies that might influence medication absorption or metabolism. However, an adverse food interaction, while potentially problematic, typically poses less immediate and severe risk than an unknown drug allergy, which can be fatal.
Choice D rationale
Allergy history is paramount because exposure to an allergen can trigger a severe, potentially life-threatening immunological response, such as anaphylaxis. Identifying known allergies prevents direct exposure to the offending agent, thereby safeguarding the patient from acute hypersensitivity reactions and ensuring immediate patient safety.

Correct Answer is ["0.45"]
Explanation
Step 1 is to determine the volume to administer. 4500 units ÷ (10,000 units/1 mL) = 0.45 mL. The nurse will administer 0.45 mL.
Correct Answer is D
Explanation
Choice A rationale
Reading newsprint at 20 inches assesses near vision, but it is not the standard clinical method for comprehensive visual acuity assessment. While it can provide some insight into the patient's functional near vision, a more precise and standardized tool like a Jaeger card or specific near vision charts are preferred for accurate diagnostic evaluation.
Choice B rationale
The Jaeger card is specifically designed to assess near visual acuity, typically held at 14 inches (35 cm) from the eye. While useful for evaluating reading vision, it does not provide information about distance visual acuity, which is a primary component of a comprehensive eye examination and is assessed using a Snellen chart.
Choice C rationale
The confrontation test assesses peripheral vision, not central visual acuity. It involves the examiner bringing fingers or objects into the patient's field of vision from various directions. While an important part of a complete eye examination to detect visual field defects, it does not quantify the sharpness of central vision.
Choice D rationale
The Snellen chart is the gold standard for assessing distance visual acuity. Positioning it 20 feet away standardizes the testing distance, allowing for accurate measurement of visual acuity as a fraction (e.g., 20/20). This provides a reliable and reproducible measure of central vision, critical for diagnosing and monitoring visual impairments.
