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.

- AWeak hip abduction
- BFoot drop

- AIt is controlled only by hormones
- BIts long refractory period lasts almost as long as the contraction
- CIt is not striated
- DIt has no calcium in the sarcoplasmic reticulum
4.Human physiologyHard
In a patient with primary hypothyroidism, you would expect:
- AHigh TSH and low free T4
- BHigh TSH and high free T4
- CLow TSH and high free T4
- DLow TSH and low free T4
5.Biology for nursing entrance examsMedium
Which structure is found in both prokaryotic and eukaryotic cells?
- AMitochondria
- BRibosomes
- CThe endoplasmic reticulum
- DA nucleus
6.Biology for nursing entrance examsHard
When caring for a patient with C. difficile infection, why is hand washing with soap and water preferred over alcohol hand rub?
- ASoap kills the spores, but alcohol only kills viruses and not bacteria
- BAlcohol makes the spores more infectious
- CAlcohol does not kill its spores, but washing removes them
- DSoap and water are faster than alcohol rub
7.Chemistry for nursing entrance examsMedium
In 2KClO₃ → 2KCl + 3O₂, how many moles of O₂ form from 4 mol of KClO₃?
- A3 mol
- B4 mol
- C6 mol
- D8 mol
8.Chemistry for nursing entrance examsHard
Which phrase best describes a 0.001 M solution of hydrochloric acid?
- AA dilute solution of a strong acid
- BA dilute solution of a weak acid
- CA concentrated solution of a strong acid
- DA concentrated solution of a weak acid
3Solutions
1.Human anatomy
Answer: B · Pulmonary veins
Why this is the answer
Four pulmonary veins drain oxygenated blood into the left atrium. They are the main exception to the rule that veins carry deoxygenated blood.
2.Human anatomy
Answer: B · Foot drop
Why this is the answer
The common fibular nerve supplies the dorsiflexors and evertors. Damage at the fibular neck causes foot drop and a high-stepping gait. The sole is supplied by the tibial nerve.
3.Human physiology
Answer: B · Its long refractory period lasts almost as long as the contraction
Why this is the answer
The plateau of the cardiac action potential gives a long refractory period, so the muscle relaxes before it can be excited again. This allows the heart to refill.
B · Its long refractory period lasts almost as long as the contraction
4.Human physiology
Answer: A · High TSH and low free T4
Why this is the answer
When the thyroid fails, low T4 removes negative feedback and the pituitary raises TSH. Low TSH with low T4 would point to secondary (pituitary) hypothyroidism.
A · High TSH and low free T4
5.Biology for nursing entrance exams
Answer: B · Ribosomes
Why this is the answer
All cells have ribosomes, a cell membrane, cytoplasm and DNA. Membrane-bound organelles such as the nucleus and mitochondria are found only in eukaryotes.
6.Biology for nursing entrance exams
Answer: C · Alcohol does not kill its spores, but washing removes them
Why this is the answer
C. difficile spores resist alcohol. Washing with soap and running water physically removes spores from the hands, so it is used along with gloves and contact precautions.
C · Alcohol does not kill its spores, but washing removes them
7.Chemistry for nursing entrance exams
Answer: C · 6 mol
Why this is the answer
4 mol KClO₃ × (3 mol O₂ ÷ 2 mol KClO₃) = 6 mol O₂.
8.Chemistry for nursing entrance exams
Answer: A · A dilute solution of a strong acid
Why this is the answer
Strength describes how fully an acid ionises; HCl ionises completely, so it is strong at any concentration. Concentration describes how much acid is in each litre; 0.001 M is dilute.
A · A dilute solution of a strong acid
