Physical Science Proctored Exam Help for Nursing & Healthcare Students

Physical science covers chemistry and physics principles relevant to nursing and healthcare. NurseQuizPrep specialists provide targeted physical science exam prep with medical and nursing applications.

Chemistry for Nursing Students

Atomic structure, periodic table, chemical bonding, acid-base chemistry (pH scale, buffers), solutions and concentrations, and basic organic chemistry relevant to pharmacology and biological systems.

• pH scale: 0-14; acids <7, neutral =7, bases >7
• Buffer systems: bicarbonate buffer (most important in body)
• Solution concentrations: molarity, % w/v (used for IV fluids and medications)

Physics for Healthcare

Pressure and fluid dynamics (Poiseuille's law — blood flow), gas laws (Boyle's law for lung mechanics, Henry's law for gas exchange), electricity (defibrillation, ECG), optics (ophthalmoscopy), and radioactivity (radiation safety in healthcare).

• Boyle's Law: pressure and volume inversely related — lung inflation mechanics
• Poiseuille's Law: blood flow ∝ radius⁴ — why vasoconstriction matters so much
• Radiation safety: time, distance, shielding — ALARA principle
