First, convert the required dose from grams to milligrams, as the medication concentration is in mg. Since 1 g = 1000 mg, 2.5 g is equal to 2500 mg. Next, set up a proportion to find the required volume in mL. The proportion is: 500 mg / 2 mL = 2500 mg / X mL. Solving for X gives (2500 mg * 2 mL) / 500 mg = 10 mL. Therefore, the nurse must draw up 10 mL.

The subject of this sentence is 'Each,' which is a singular indefinite pronoun. Therefore, the verb must also be singular. The correct verb form is 'requires,' not 'require.' The prepositional phrase 'of the patients' does not affect the subject-verb agreement.

Amelioration means the act of making something better or improving it. In a medical context, it refers to the reduction or improvement of symptoms or a condition. 'Exacerbation' is an antonym, meaning a worsening of symptoms. 'Diagnosis' is the identification of a disease, and 'complication' is a secondary problem that arises.

Active transport moves substances against their concentration gradient (from low to high concentration), which requires cellular energy (ATP). The sodium-potassium pump is a classic example.

Endocytosis is the process by which cells take in large particles or substances by engulfing them, forming a vesicle. This process requires energy (ATP) to change the shape of the cell membrane. Osmosis and facilitated diffusion are forms of passive transport and do not require ATP.

To calculate the total intake, each amount must be converted to milliliters and then summed.

1. Juice: 6 oz * 30 mL/oz = 180 mL
2. Coffee: 1 cup * 240 mL/cup = 240 mL
3. Water: 0.5 * 500 mL = 250 mL
   Total Intake = 180 mL + 240 mL + 250 mL = 670 mL.
   The output information (urinary and drain) is not needed to answer the question about intake.

The passage discusses multiple aspects of diabetes management (diet, exercise, medication), the progression of treatment (from oral meds to insulin), corrects a misconception, and stresses the importance of adherence to avoid complications. This encompasses the entire message, making it the main idea. The other options are either directly contradicted by the text or are supporting details rather than the central theme.

This statement is false. The definition of arteries and veins is based on the direction of blood flow relative to the heart, not oxygenation status. Arteries carry blood away from the heart, and veins carry blood toward the heart. The pulmonary artery carries deoxygenated blood from the heart to the lungs, and the pulmonary veins carry oxygenated blood from the lungs back to the heart.

The prefix 'hypo-' means below, under, or deficient. Examples include 'hypoglycemia' (low blood sugar) and 'hypotension' (low blood pressure). 'Hyper-' means above or excessive. 'Inter-' means between. 'Intra-' means within.

The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH below 7 is acidic, and a pH above 7 is alkaline (or basic). Since 8.5 is slightly above 7, the solution is classified as weakly alkaline.

The prefix 'milli-' means one-thousandth. Therefore, there are 1000 milliliters in 1 liter. To convert liters to milliliters, you multiply the number of liters by 1000. So, 1.5 L * 1000 mL/L = 1500 mL.
