_____ milliliters of polysorbate 80 (SG = 1.08) are needed to prepare a prescription that includes 48 grams of the surfactant/emulsifier (polysorbate)? Round to the nearest hundredth. Do not include units.

SCHOLAR-MAC is a standardized patient assessment mnemonic used in community pharmacy and primary care to systematically evaluate a patient's self-reported symptoms. The "A" in the acronym stands for Aggravating factors, which are specific triggers that exacerbate the patient's discomfort. Identifying these factors helps the clinician distinguish between different pathological conditions and determine the appropriate level of intervention or referral.

Rationale:

A. Asking what makes the symptoms better addresses the Remediating factors of the clinical presentation. This information is valuable for understanding what treatments or positions provide relief, but it does not identify what causes the condition to worsen. It is the functional opposite of assessing aggravating triggers during the patient interview.

B. Asking "What makes the symptoms worse?" directly identifies aggravating factors. This question uncovers external or internal stimuli, such as specific foods, physical activities, or environmental exposures, that increase the severity of the illness. Pinpointing these triggers is essential for forming a differential diagnosis and providing effective lifestyle advice to the patient.

C. Asking when the symptoms started is used to assess the Onset of the condition. This helps the provider establish a timeline and determine if the issue is acute or chronic. While the timing is a critical component of the SCHOLAR assessment, it does not provide information regarding the factors that worsen the patient's distress.

D. Asking if this has happened in the past is part of the History section of the assessment. Understanding the recurrence of a symptom can indicate a chronic underlying problem or a pattern of seasonal triggers. However, a past occurrence is a temporal observation and does not explain the specific stimuli that aggravate the current episode.

Step 1 is to convert the weight from pounds (lbs) to kilograms (kg)

Weight in kg = 154 ÷ 2.2

154 ÷ 2.2 = 70

Result at this step = 70 kg

Step 2 is to calculate the total volume (mL) to be administered

Volume = Weight in kg × Dose (mL/kg)

70 × 0.06 = 4.2

Result at this step = 4.2 mL

Step 3 is to calculate the dose in units

Total Units = Total mL × Concentration (IU/mL)

4.2 × 312 = 1310.4

Result at this step = 1310.4

Step 4 is to round to the nearest tenth

1310.4 = 1310.4

Answer: 1310.4
