1Formulas and methods

Pre-nursing math (entrance exam)

Order of operations
parentheses → exponents → × ÷ (left to right) → + − (left to right)
Fractions
a/b + c/d = (ad + bc)/bd, a/b × c/d = ac/bd, a/b ÷ c/d = a/b × d/c
Percent
p% of N = (p/100)·N; percent = part/whole × 100
Percent change
(new − original)/original × 100
Discount, then tax
price × (1 − d/100) × (1 + t/100)
Proportion
a/b = c/d → ad = bc
Mean, median, mode, range
sum/count; middle of ordered list; most frequent; max − min
Length, capacity, time
1 km = 1000 m, 1 m = 100 cm, 1 ft = 12 in, 1 yd = 3 ft, 1 mi = 5280 ft, 1 gal = 4 qt = 16 cups, 1 h = 60 min
Temperature
°F = °C·9/5 + 32, °C = (°F − 32)·5/9; a change of 1 °C = 1.8 °F
Area
rectangle l·w, triangle ½·b·h, circle π·r²
Perimeter and circumference
rectangle 2l + 2w, circle π·d = 2π·r
Volume
box l·w·h, cylinder π·r²·h; 1000 cm³ = 1 L
Speed
distance ÷ time (time in hours for mph or km/h)

Method

  1. Read the last sentence first: what exactly is asked, and in which unit or form (lowest terms, nearest cent, one decimal place)?
  2. Write the numbers in one form: turn mixed numbers into improper fractions, percents into decimals, and hours and minutes into one unit.
  3. Pick the method: PEMDAS for expressions, a common denominator for adding fractions, part ÷ whole × 100 for percents, cross-multiplying for proportions, inverse operations for equations.
  4. Work one step at a time and write each line down; round only at the very end.
  5. Check the size of the answer with an estimate, and put an equation’s answer back in.

Nursing math & unit conversions

Metric steps
1 kg = 1000 g, 1 g = 1000 mg, 1 mg = 1000 mcg, 1 L = 1000 mL
Weight and length
1 kg = 2.2 lb, 1 lb = 16 oz, 1 in = 2.54 cm, 1 ft = 12 in
Household measures
1 tsp = 5 mL, 1 tbsp = 15 mL, 1 fl oz = 30 mL, 1 cup = 8 fl oz = 240 mL
Temperature
°C = (°F − 32)·5/9, °F = °C·9/5 + 32
24-hour clock
PM hours 1–11: add 12; 12 AM = 00:xx; 12 PM = 12:xx
Dose rate
mcg/min × 60/1000 = mg/h
Laboratory factors
glucose 1 mmol/L = 18 mg/dL; creatinine 1 mg/dL = 88.4 µmol/L; Hb 1 g/dL = 10 g/L

Method

  1. Write the given quantity with its unit and the unit you want.
  2. Pick the equivalent: 1000 between kg, g, mg and mcg or L and mL; 1 kg = 2.2 lb; 1 tsp = 5 mL, 1 tbsp = 15 mL, 1 fl oz = 30 mL, 1 cup = 240 mL.
  3. Write it as a fraction so that the unwanted unit cancels; for a rate, use one fraction per unit that changes.
  4. Check the direction: a smaller unit gives a bigger number.
  5. Round only the final answer, to the precision the question names.

Reading comprehension (entrance exams)

Method

  1. Read the question first so you know what you are looking for.
  2. Skim the passage for its topic and main point; the first or last sentence often states it.
  3. Go back to the exact lines that answer the question.
  4. For inferences, choose the option the clues most strongly support, not one that goes further.
  5. For labels and tables, apply every rule that fits the case and do the small calculation carefully.

Healthcare vocabulary (entrance exams)

Method

  1. Read the whole sentence and look for a context clue: a definition, a contrast, an example or a cause and effect.
  2. Split an unfamiliar word into prefix, root and suffix and translate each part.
  3. Read a medical term from the suffix back to the start (hepat-itis: inflammation of the liver).
  4. Put each option into the sentence and check that the meaning still fits.
  5. Choose the meaning used in this sentence, even if the word has another everyday meaning.

English grammar & language usage (entrance exams)

Method

  1. Find the subject and the verb of the sentence before choosing a form.
  2. Strip away phrases (of the …, along with …) and extra people (you and …) to test agreement and pronoun case.
  3. Check each clause: can it stand alone? Join independent clauses with a comma + conjunction or a semicolon.
  4. Check modifiers and lists: the describing phrase next to its word, items in the same form.
  5. For word choice and register, pick the precise, formal and concise option.

Biology for nursing entrance exams

Method

  1. Name the topic of the question: cell parts, transport, division, DNA and protein synthesis, inheritance, biomolecules, microorganisms or experimental design.
  2. 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.
  3. For crosses, write the parents’ genotypes, list the gametes and fill a Punnett square before counting.
  4. For experiments, label the independent, dependent and controlled variables, and ask whether the evidence supports or only suggests the conclusion.
  5. Check each option against the question asked, not just whether it is a true statement.

Chemistry for nursing entrance exams

Method

  1. Identify what is given and asked: particles, a formula, a state change, a concentration, a pH or a mass.
  2. Use the periodic table: the atomic number gives protons, the group gives valence electrons and the usual ion charge.
  3. Balance equations with coefficients only, element by element, oxygen and hydrogen last.
  4. For amounts, go mass → moles → mole ratio → moles → mass, and for solutions use M = mol/L and C₁V₁ = C₂V₂.
  5. Remember that pH is logarithmic: one unit is a factor of 10.

3Solutions

1.Pre-nursing math (entrance exam)

Answer: x = 9

Order of operations (PEMDAS/BODMAS): work inside parentheses first, then exponents (powers), then multiplication and division from left to right, and last addition and subtraction from left to right. Multiplication does not come before division, and addition does not come before subtraction: each pair is done in the order it appears. A negative number in parentheses keeps its sign when squared: (−3)² = 9, but −3² = −9.

One operation at a time

Multiplication and division go from left to right: divide 21 by 3 first.

x = 21 ÷ 3 × 2 − 5
= 7 × 2 − 5
= 14 − 5

Result

x = 9

Answer

x = 9
2.Pre-nursing math (entrance exam)

Answer: x = 41.5 km

Rates and scales: speed = distance ÷ time, with the time in the unit of the answer (2 h 15 min = 2.25 h, because 15 min = 15/60 h). A map scale is a proportion: 1 cm on the map stands for a fixed distance on the ground, so multiply the map distance by it.

Multiply by the scale

x = 8.3 × 5 = 41.5 km

Answer

x = 41.5 km
3.Nursing math & unit conversions

Answer: T = 100.2 °F

Temperature: °C = (°F − 32) × 5/9 and °F = °C × 9/5 + 32. Subtract 32 before you multiply when going from °F, and add 32 after you multiply when going from °C. A quick check: 37 °C is 98.6 °F, and every 1 °C is 1.8 °F.

Multiply by 9/5

37.9·9/5 = 68.22

Add 32

T = 68.22 + 32 = 100.2 °F

Answer

T = 100.2 °F
4.Nursing math & unit conversions

Answer: V = 260 mL

Household measures and weight: nursing exams use rounded equivalents: 1 teaspoon (tsp) = 5 mL, 1 tablespoon (tbsp) = 15 mL = 3 tsp, 1 fluid ounce (fl oz) = 30 mL = 2 tbsp, and 1 cup = 8 fl oz = 240 mL. For weight, 1 kg = 2.2 lb and 1 lb = 16 oz; for length, 1 inch = 2.54 cm. Set the conversion up so that the unit you do not want cancels out.

Each item in mL

1 tbsp = 1·15 = 15 mL
1 tsp = 1·5 = 5 mL
1 cup = 1·240 = 240 mL

Add

V = 15 + 5 + 240 = 260 mL

Answer

V = 260 mL
5.Reading comprehension (entrance exams)

Answer: B · To check for possible interactions

Why this is the answer

Some medicines, vitamins and herbal products can interact. Asking about everything she takes helps the pharmacist check that the new prescription is safe.

Answer

B · To check for possible interactions
6.Reading comprehension (entrance exams)

Answer: B · The mayor avoided the question.

Why this is the answer

Speaking at length about other topics instead of the bridge suggests that the mayor was avoiding the question.

Answer

B · The mayor avoided the question.
7.Healthcare vocabulary (entrance exams)

Answer: B · Breathing food or fluid into the lungs

Why this is the answer

Aspiration is the inhaling of food, fluid or other material into the airway and lungs.

Answer

B · Breathing food or fluid into the lungs
8.Healthcare vocabulary (entrance exams)

Answer: B · Grow steadily worse

Why this is the answer

To deteriorate is to become progressively worse in condition or quality.

Answer

B · Grow steadily worse
9.English grammar & language usage (entrance exams)

Answer: D · their

Why this is the answer

The antecedent is “the nurse and the aide”, a compound joined by “and”, so the plural pronoun “their” agrees with it.

Answer

D · their
10.English grammar & language usage (entrance exams)

Answer: A · On the other hand

Why this is the answer

“On the other hand” introduces a contrasting point. “Therefore” would wrongly say the savings caused the drop, and “similarly” shows likeness.

Answer

A · On the other hand
11.Human anatomy

Answer: C · Mitral (bicuspid) valve

Why this is the answer

The mitral (bicuspid) valve separates the left atrium and left ventricle; the tricuspid valve does the same on the right side.

Answer

C · Mitral (bicuspid) valve
12.Human anatomy

Answer: D · Posterior superior temporal gyrus of the dominant hemisphere

Why this is the answer

This is Wernicke's (receptive) aphasia, caused by damage to Wernicke's area in the posterior superior temporal gyrus. Broca's area in the inferior frontal gyrus causes non-fluent aphasia.

Answer

D · Posterior superior temporal gyrus of the dominant hemisphere
13.Human physiology

Answer: D · Stroke volume rises when ventricular filling increases

Why this is the answer

Greater end-diastolic volume stretches the myocardium, which increases the force of contraction and the stroke volume, matching output to venous return.

Answer

D · Stroke volume rises when ventricular filling increases
14.Human physiology

Answer: A · Tachycardia, cool pale skin and reduced urine output

Why this is the answer

Baroreceptor-driven sympathetic activation raises heart rate and constricts skin vessels. Reduced renal perfusion, ADH and aldosterone lower urine output.

Answer

A · Tachycardia, cool pale skin and reduced urine output
15.Biology for nursing entrance exams

Answer: C · It uses energy to move substances against a concentration gradient

Why this is the answer

Active transport uses ATP and carrier proteins (pumps) to move substances from low to high concentration. Diffusion and osmosis are passive.

Answer

C · It uses energy to move substances against a concentration gradient
16.Biology for nursing entrance exams

Answer: C · Hydrolysis, which uses a water molecule

Why this is the answer

Hydrolysis breaks a bond by adding water across it, as when sucrase splits sucrose. Dehydration synthesis is the reverse: it joins monomers and releases water.

Answer

C · Hydrolysis, which uses a water molecule
17.Chemistry for nursing entrance exams

Answer: C · The equilibrium shifts toward the reactants

Why this is the answer

For an exothermic reaction, heat is like a product. Adding heat shifts the equilibrium backward to absorb it, so the yield of products falls.

Answer

C · The equilibrium shifts toward the reactants
18.Chemistry for nursing entrance exams

Answer: B · More protons pull the electrons of the same outer shell closer

Why this is the answer

Across a period, each element has one more proton but its outer electrons are in the same shell with similar shielding. The stronger nuclear charge pulls the electrons in, so the atom gets smaller.

Answer

B · More protons pull the electrons of the same outer shell closer
