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.

- CL5
- DL3
3.Human physiologyMedium
How does glucagon raise blood glucose?
- AIt stimulates glycogen breakdown and gluconeogenesis in the liver
- BIt stimulates glucose uptake by muscle
- CIt slows glucose absorption from the gut
- DIt blocks insulin receptors on fat cells
4.Human physiologyHard
In the renin–angiotensin–aldosterone system, where is angiotensin I mainly converted to angiotensin II?
- AIn the adrenal cortex
- BIn the lungs
- CIn the kidneys' juxtaglomerular cells
- DIn the liver
5.Biology for nursing entrance examsMedium
What happens during telophase of mitosis?
- AThe DNA is copied for the next division
- BThe sister chromatids are pulled apart
- CThe chromosomes line up across the middle of the cell
- DA nuclear envelope forms around each set of chromosomes
6.Biology for nursing entrance examsHard
Why is ATP described as an energy carrier rather than a long-term energy store?
- ACells hold only a little and constantly recycle it from ADP
- BATP is stored in large amounts in fat tissue
- CATP contains no energy in its bonds, so it cannot be stored
- DATP can be made only in plants
7.Chemistry for nursing entrance examsMedium
A reaction is at equilibrium. More of one reactant is added. According to Le Chatelier's principle, what happens?
- AThe reaction stops completely
- BThe equilibrium shifts toward the products
- CNothing changes
- DThe equilibrium shifts toward the reactants
8.Chemistry for nursing entrance examsHard
At the top of a high mountain, air still contains about 21% oxygen. Why do climbers still get less oxygen with each breath?
- ACold air contains no oxygen
- BThe total air pressure is lower, so the partial pressure of oxygen is lower
- COxygen is heavier, so it all sinks to sea level
- DThe percentage of oxygen in the air falls sharply as you climb higher
3Solutions
1.Human anatomy
Answer: B · Abducens nerve (VI)
Why this is the answer
The abducens nerve (VI) supplies lateral rectus. A lesion stops the eye moving outwards and causes horizontal double vision.
2.Human anatomy
Answer: C · L5
Why this is the answer
A posterolateral L4–L5 herniation usually catches the traversing L5 root, causing weakness of big toe extension and numbness on the top of the foot.
3.Human physiology
Answer: A · It stimulates glycogen breakdown and gluconeogenesis in the liver
Why this is the answer
Glucagon from alpha cells acts on the liver to break down glycogen and make new glucose from non-carbohydrate sources.
A · It stimulates glycogen breakdown and gluconeogenesis in the liver
4.Human physiology
Answer: B · In the lungs
Why this is the answer
Renin (kidney) cleaves angiotensinogen (liver) to angiotensin I, which ACE, mainly on pulmonary capillary endothelium, converts to angiotensin II.
5.Biology for nursing entrance exams
Answer: D · A nuclear envelope forms around each set of chromosomes
Why this is the answer
In telophase the chromosomes arrive at the poles and uncoil, and a new nuclear envelope forms around each set. Cytokinesis then completes the division into two cells.
D · A nuclear envelope forms around each set of chromosomes
6.Biology for nursing entrance exams
Answer: A · Cells hold only a little and constantly recycle it from ADP
Why this is the answer
Cells keep only a small amount of ATP and remake it all the time from ADP and phosphate using energy from respiration. Long-term energy is stored as glycogen and fat.
A · Cells hold only a little and constantly recycle it from ADP
7.Chemistry for nursing entrance exams
Answer: B · The equilibrium shifts toward the products
Why this is the answer
Le Chatelier's principle: a system at equilibrium shifts to oppose a change. Adding reactant is opposed by making more product.
B · The equilibrium shifts toward the products
8.Chemistry for nursing entrance exams
Answer: B · The total air pressure is lower, so the partial pressure of oxygen is lower
Why this is the answer
The oxygen fraction stays near 21%, but the total pressure is lower, so the oxygen partial pressure (0.21 × total pressure) falls. Less O₂ diffuses into the blood, which can cause altitude sickness.
B · The total air pressure is lower, so the partial pressure of oxygen is lower
