Only implementation cost matters
B.
A sound evaluation compares outcomes with objectives, costs, alternatives and distributional effects
C.
A policy is successful merely because it was announced
D.
Evaluation should ignore evidence
Show Answer
Correct Answer: B. A sound evaluation compares outcomes with objectives, costs, alternatives and distributional effects
Explanation:
Policy evaluation considers effectiveness, efficiency, equity and causal evidence.

A.
Stroke volume is unrelated to venous return
B.
Afterload can never influence ejection
C.
Cardiac output equals heart rate multiplied by stroke volume and changes with preload, contractility and afterload
D.
Cardiac output equals blood pressure divided by temperature
Show Answer
Correct Answer: C. Cardiac output equals heart rate multiplied by stroke volume and changes with preload, contractility and afterload
Explanation:
Cardiac output integrates rate and stroke volume, while loading conditions and contractility influence stroke volume.

A.
All mediators have identical effects
B.
Inflammation occurs without signalling molecules
C.
Inflammatory mediators coordinate vascular change, leukocyte recruitment and local symptoms
D.
Acute inflammation never recruits leukocytes
Show Answer
Correct Answer: C. Inflammatory mediators coordinate vascular change, leukocyte recruitment and local symptoms
Explanation:
Multiple mediators act on vessels, cells and tissues to produce the organised inflammatory response.

A.
DNA repair has no relevance to cancer risk
B.
Tumours are unrelated to selection among cell clones
C.
A single mutation always produces invasive cancer immediately
D.
Cancer develops through accumulated alterations affecting growth control, survival, repair and the tissue environment
Show Answer
Correct Answer: D. Cancer develops through accumulated alterations affecting growth control, survival, repair and the tissue environment
Explanation:
Tumorigenesis is multistep and reflects genetic, epigenetic and microenvironmental selection.

A.
Clearance relates elimination rate to drug concentration and helps determine maintenance dosing
B.
Clearance has no relationship to elimination
C.
Clearance is the same as absorption fraction
D.
Maintenance dosing depends only on tablet colour
Show Answer
Correct Answer: A. Clearance relates elimination rate to drug concentration and helps determine maintenance dosing
Explanation:
Systemic clearance describes the effective volume cleared per unit time and links concentration to elimination rate.

A.
A competitive antagonist increases agonist potency by shifting the concentration-response curve left while leaving receptor occupancy unchanged
B.
A reversible competitive antagonist shifts an agonist concentration-response curve to the right without reducing maximal response when enough agonist is available
C.
An irreversible antagonist permanently occupies receptors, so increasing agonist concentration fully restores the original maximal response
D.
A reversible competitive antagonist necessarily lowers the maximal response even when much higher agonist concentrations are available
Show Answer
Correct Answer: B. A reversible competitive antagonist shifts an agonist concentration-response curve to the right without reducing maximal response when enough agonist is available
Explanation:
Competition at the same receptor can be overcome by higher agonist concentration, reducing apparent potency but not efficacy.

A.
Antibiotics deliberately teach each bacterium to resist
B.
Stopping all infection control prevents resistance
C.
Antibiotic exposure can select resistant organisms already carrying or acquiring resistance determinants
D.
Resistance has no genetic basis
Show Answer
Correct Answer: C. Antibiotic exposure can select resistant organisms already carrying or acquiring resistance determinants
Explanation:
Selection favours resistant variants, while transmission and gene exchange can spread resistance.

A.
Specific lymphocytes activate without any signal
B.
Co-stimulation is irrelevant to immune tolerance
C.
Cytokines cannot influence cell differentiation
D.
Antigen recognition plus appropriate co-stimulation and cytokine signals shape lymphocyte activation and differentiation
Show Answer
Correct Answer: D. Antigen recognition plus appropriate co-stimulation and cytokine signals shape lymphocyte activation and differentiation
Explanation:
Adaptive responses integrate receptor specificity with co-stimulatory and environmental signals.

A.
Measurement methods cannot introduce systematic error
B.
Bias is a systematic error in selection, measurement or analysis that can distort an estimated association
C.
Bias is eliminated automatically by a large sample
D.
Random error and bias are identical
Show Answer
Correct Answer: B. Bias is a systematic error in selection, measurement or analysis that can distort an estimated association
Explanation:
Larger samples reduce random error but do not necessarily correct systematic design or measurement problems.
