Great question. Two variables can move together without one causing the other — a hidden confounding factor often explains both. Classic example: ice cream sales and drowning both rise in summer, but ice cream doesn't cause drowning. On the HSRT, always ask: is there a lurking variable?

Correlation vs Causation
Breaking Down Scenarios
Every HSRT scenario requires identifying the core question before evaluating evidence. Decompose first, then decide.
Key concept
Identify: What is claimed? What evidence supports it? What assumptions are hidden?
Exam tip
The HSRT tests reasoning, not memorized facts. A student who knows no anatomy can outscore one who does.

Which statement accurately describes the outcome of mitosis in human somatic cells?
AMitosis produces four genetically unique daughter cells
BMitosis produces two genetically identical daughter cells
CMitosis is used exclusively for sexual reproduction
DMitosis produces cells with half the parent chromosome number
✓ Correct. Mitosis produces two diploid daughter cells with identical genetic material. Meiosis — not mitosis — produces four unique haploid cells for sexual reproduction.

Tachycardia

Definition
Abnormally rapid heart rate, typically >100 bpm at rest. From Greek tachys (swift) + kardia (heart).
A client taking warfarin asks if they can eat spinach. What is the nurse's best response?
✗ You: “Avoid all leafy greens”✓ Correct: “Keep portions consistent”
Why your answer was wrong
Telling patients to avoid all leafy greens is overly restrictive. Complete elimination is unnecessary and may compromise nutrition.
Why the correct answer works
Warfarin's effect is managed against consistent Vitamin K intake. Consistency — not elimination — is the key principle. Abrupt changes destabilize INR levels.
Clinical Scenario — NGN
A 68-year-old post-op day 1 patient reports shortness of breath. SpO₂ 91% on room air, RR 22/min, HR 98 bpm. Lungs clear bilaterally. Patient anxious but oriented.
Which nursing actions are appropriate? (Select all that apply)
A.Administer prescribed PRN oxygen at 2L via nasal cannula
B.Immediately call a rapid response team
C.Reposition to semi-Fowler's position (30–45°)
D.Hold all scheduled medications until SpO₂ normalizes
E.Reassess respiratory status in 15 minutes and document
