Pharmacology Questions for the RMA Exam — Practice Free

To convert pounds (lb) to kilograms (kg), divide the weight in pounds by 2.2. Calculation: 44 lb / 2.2 = 20 kg. Clinical Pearl: Weight-based dosing is standard in pediatrics to prevent medication errors. Always round to the nearest tenth unless facility policy states otherwise. AMT Exam Strategy: The AMT exam frequently tests this conversion as it is the foundation for pediatric pharmacology. Remember: lb to kg (divide by 2.2); kg to lb (multiply by 2.2). Common distractor: multiplying by 2.2 instead of dividing.

Use the final concentration after reconstitution: (Desired / Have) x Quantity = (250 mg / 500 mg) x 2 mL = 0.5 x 2 mL = 1 mL. Rationale: The amount of diluent added (4.8 mL) creates the total volume, but the dosage calculation must be based on the resulting concentration (500 mg per 2 mL). Always read the label for the concentration after reconstitution rather than the total vial volume.

Right Technique and Right Route. This involves selecting the correct needle length (1.5 to 3 inches for obese patients) and angle (90 degrees). Strategy Tip: AMT frequently asks about site selection. The ventrogluteal site is often cited as the safest for large-volume IM injections because it is away from major nerves and blood vessels.

Fluoroquinolones carry a Black Box Warning for increased risk of tendonitis and tendon rupture, most commonly the Achilles tendon. This risk is higher in patients over 60, those taking corticosteroids, or transplant recipients. AMT Exam Strategy: If a patient calls complaining of heel pain while on floxacins, the MA should instruct them to stop the medication, rest the area, and seek immediate evaluation.

Risk: Hypokalemia (low potassium), as Furosemide is a loop diuretic that causes the kidneys to excrete sodium, water, and potassium. Recommendations: Increase intake of potassium-rich foods (bananas, orange juice, potatoes, spinach) or take a prescribed potassium supplement (e.g., K-Dur). Clinical Manifestations: Monitor for muscle cramps, weakness, and cardiac arrhythmias. Contrast this with Spironolactone (Aldactone), which is a potassium-sparing diuretic and carries a risk of hyperkalemia.
