The physician has ordered SoluMedrol 75 mg IM. How many milliliters will the nurse administer? (Use LABEL #4 - SoluMedrol: ROUND TO TENTHS PLACE: LABEL CORRECTLY TO RECEIVE CREDIT)

Step 1 is to locate the medication label. It is stated that Label #4 contains SoluMedrol.

Step 2 is to identify the concentration of SoluMedrol on Label #4. Assuming Label #4 indicates SoluMedrol 125 mg/2 mL (This is a common concentration; specific label details are not provided in the prompt, so a typical concentration is assumed for calculation purposes).

Step 3 is to calculate the volume to be administered. Volume (mL) = (Ordered dose ÷ Available concentration). Volume (mL) = (75 mg ÷ 125 mg/2 mL). Volume (mL) = (75 mg ÷ 125 mg) × 2 mL. Volume (mL) = 0.6 × 2 mL. Volume (mL) = 1.2 mL. The nurse will administer 1.2 mL.

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.
