Short answer: Paediatric nursing for the DHA exam: dosing and development questions test two skills. First, safe weight-based doses using current weight in kilograms and a maximum cap. Second, matching your words and actions to the child’s age. Learn the approximate milestones, then practise calculations and short scenarios.
Paediatric nursing for the DHA exam: dosing and development
Paediatric items often pair a number with a person. You calculate a dose, then choose how to explain it to a three-year-old or a teenager. The paediatric nursing revision map covers fluids and safeguarding. This page covers dosing checks and development.
Meddex is independent and is not connected to the Dubai Health Authority (DHA) or Prometric. We could not confirm the exam’s depth for paediatrics, so learn principles you can apply.
This is exam-preparation revision, not clinical guidance. In practice, follow your own organisation’s policies and the current guideline, and check doses and thresholds against them.
Dosing: the checks before the sum
Children are not small adults, and doses are set by weight. Before calculating, confirm the weight is current and in kilograms, the allergy status, the drug and concentration on the label and the usual range in your unit’s reference. Then compare your answer with the stated maximum single dose. A calculated dose must never exceed the adult dose.
- Use an oral syringe to measure liquids, not a household spoon.
- Check the concentration, because the same medicine can come in more than one strength.
- Ask for a second check where policy requires one.
- Involve the parent or carer, and still check identity with the wristband.
A worked dose
Example, written by Meddex, with an invented prescription. Ordered: 15 mg per kg. The child weighs 12 kg, so the dose is 180 mg. The liquid is 120 mg in 5 mL. 180 divided by 120 is 1.5, and 1.5 times 5 mL is 7.5 mL. Now ask: is 7.5 mL a sensible volume for a child of this size? Yes. If you had reached 75 mL, you would stop. See the drug calculations guide for the method.
Development: commonly taught milestones
These ages are approximate, because children vary. Questions usually ask what is expected, or what needs referral.
- Around 2 months: social smile.
- Around 6 months: sits with support and then alone soon after, and may show stranger anxiety.
- Around 12 months: first words and first steps, with walking often arriving by about 18 months.
- Around 2 years: two-word phrases.
- Around 3 to 4 years: stands on one foot briefly and asks many questions.
Theories that exams like
Piaget describes sensorimotor thinking from birth to about two years, preoperational thinking to about seven, concrete operational thinking to about eleven and formal operational thinking after that. Erikson names trust versus mistrust in infancy, autonomy versus shame in toddlers and initiative versus guilt in preschool children. Use them to choose an approach rather than to recite names.
Matching your approach to age
Infants need a calm voice, warmth and a parent nearby. Toddlers need simple choices that are safe, such as which arm, and short explanations. Preschool children think in magic and may believe an injection is a punishment, so say that it is not. School-age children want facts and a role. Adolescents need privacy, honesty and respect for their growing independence. Safeguarding concerns follow the pattern in the earlier guide.
Example: the frightened toddler
Example, written by Meddex. A two-year-old screams when the nurse approaches with a thermometer. The best response is to let the toddler hold the device, explain in two short sentences, keep the parent close and then proceed. Delaying the task for hours, restraining without trying other methods or reasoning at length are poorer choices.
How to practise
Write one age on each card and add what the child can do, what scares them and how you would explain a procedure. Review with the flashcards method, and repeat the dose check on paper each time.
Pain, fever and safe handling in a child
Assess pain with a tool suited to the age, such as a faces scale for a young child, and treat it rather than assuming that children feel less. For a feverish child, look at how the child appears, how they are breathing, how they are drinking and whether there is a rash that does not fade, before you focus on the temperature. Never give aspirin to a child unless a prescriber has a specific reason, because of the risk of a serious liver and brain illness. Cot sides stay up, and a baby is never left alone on a table.
