1Formulas and methods
Biology for nursing entrance exams
Method
- Name the topic of the question: cell parts, transport, division, DNA and protein synthesis, inheritance, biomolecules, microorganisms or experimental design.
- Recall the key rule: A–T and G–C, diffusion from high to low, water moves towards more solute, mitosis keeps and meiosis halves the chromosome number.
- For crosses, write the parents’ genotypes, list the gametes and fill a Punnett square before counting.
- For experiments, label the independent, dependent and controlled variables, and ask whether the evidence supports or only suggests the conclusion.
- Check each option against the question asked, not just whether it is a true statement.
Chemistry for nursing entrance exams
Method
- Identify what is given and asked: particles, a formula, a state change, a concentration, a pH or a mass.
- Use the periodic table: the atomic number gives protons, the group gives valence electrons and the usual ion charge.
- Balance equations with coefficients only, element by element, oxygen and hydrogen last.
- For amounts, go mass → moles → mole ratio → moles → mass, and for solutions use M = mol/L and C₁V₁ = C₂V₂.
- Remember that pH is logarithmic: one unit is a factor of 10.

- AMgO
- BMgO₂
- CMg₂O₂
- DMg₂O

- ASugar reacts with water to form a new compound
- BThe sugar molecules stay sugar and can be recovered

3Solutions
1.Human anatomy
Answer: A · Ampulla of the uterine tube
Why this is the answer
Fertilisation usually occurs in the ampulla of the uterine (fallopian) tube. The embryo then travels to the uterus to implant.
A · Ampulla of the uterine tube
2.Human anatomy
Answer: B · Oculomotor nerve (III)
Why this is the answer
The oculomotor nerve supplies most eye muscles, levator palpebrae and the pupil constrictor. Lesion leaves lateral rectus and superior oblique unopposed, so the eye goes down and out.
B · Oculomotor nerve (III)
3.Human physiology
Answer: C · Muscle spindle
Why this is the answer
Tapping the tendon stretches quadriceps muscle spindles. Their afferents synapse directly on motor neurons in a monosynaptic reflex that contracts the muscle.
4.Human physiology
Answer: C · Local metabolites such as CO₂, H⁺, K⁺ and adenosine dilate the arterioles
Why this is the answer
Active hyperaemia: metabolites produced by working muscle relax arteriolar smooth muscle locally, overriding sympathetic vasoconstriction in that tissue.
C · Local metabolites such as CO₂, H⁺, K⁺ and adenosine dilate the arterioles
5.Biology for nursing entrance exams
Answer: A · Fats into fatty acids and glycerol
Why this is the answer
Lipase digests lipids such as triglycerides into fatty acids and glycerol. Proteases digest proteins, and amylase digests starch.
A · Fats into fatty acids and glycerol
6.Biology for nursing entrance exams
Answer: A · Its rate of photosynthesis equals its rate of respiration
Why this is the answer
At low light, the gas made by photosynthesis is exactly used by respiration, and vice versa. This is the compensation point. In brighter light, photosynthesis is faster and the plant releases oxygen overall.
A · Its rate of photosynthesis equals its rate of respiration
7.Chemistry for nursing entrance exams
Answer: A · MgO
Why this is the answer
One Mg²⁺ (2+) balances one O²⁻ (2−), so the formula is MgO. Mg₂O₂ has the right ratio but formulas of ionic compounds use the simplest ratio.
8.Chemistry for nursing entrance exams
Answer: B · The sugar molecules stay sugar and can be recovered
Why this is the answer
Dissolving spreads intact sugar molecules among water molecules. No new substance forms, and evaporation recovers the sugar.
B · The sugar molecules stay sugar and can be recovered
