Apgar scoring and the first minutes
The Apgar score assesses five parameters — heart rate, respiratory effort, muscle tone, reflex irritability and colour — each scored zero, one or two, at one and five minutes after birth, and every five minutes thereafter if the score remains below seven. A total of seven to ten indicates the newborn is adapting well, four to six indicates moderate difficulty requiring stimulation and oxygen, and zero to three requires immediate resuscitation.
Heart rate is the most important single parameter: absent scores zero, below one hundred scores one, and one hundred or above scores two. Colour rarely earns a full two at one minute because acrocyanosis — blue hands and feet with a pink trunk — is normal in the first twenty-four hours and scores one. Understanding that detail prevents the most common miscalculation in practice questions.
Immediate priorities after birth follow airway, breathing, circulation and then thermoregulation. The newborn is dried thoroughly, stimulated, placed skin to skin or under a radiant warmer with a hat, and the airway is cleared with the mouth suctioned before the nose so that a gasp triggered by nasal suctioning does not draw secretions into the lungs.
| Sign | 0 | 1 | 2 |
|---|---|---|---|
| Heart rate | Absent | Below 100 | 100 or above |
| Respiratory effort | Absent | Slow, irregular, weak cry | Good cry |
| Muscle tone | Limp | Some flexion | Active motion |
| Reflex irritability | No response | Grimace | Cry, cough or sneeze |
| Colour | Pale or blue | Acrocyanosis | Completely pink |
Vital signs, measurements and normal variations
Normal ranges are worth memorizing exactly: heart rate one hundred ten to one hundred sixty beats per minute, rising with crying and falling during sleep; respirations thirty to sixty per minute, irregular with brief pauses of less than twenty seconds; axillary temperature thirty-six point five to thirty-seven point five degrees Celsius; and blood pressure around sixty to eighty over forty to fifty. Respirations are diaphragmatic and newborns are obligate nose breathers.
Skin findings generate many items because so many alarming appearances are normal. Milia are tiny white sebaceous cysts across the nose and chin. Erythema toxicum is a blotchy red rash with pale centres that requires no treatment. Mongolian spots, now often called congenital dermal melanocytosis, are bluish areas over the sacrum documented at birth so they are not mistaken for bruising. Vernix caseosa, lanugo and physiological desquamation are all expected.
Head findings must be distinguished. Caput succedaneum is diffuse scalp oedema that crosses suture lines and resolves in days; cephalohaematoma is a collection of blood beneath the periosteum that does not cross suture lines, appears hours after birth and raises jaundice risk as it resorbs. Molding, the anterior and posterior fontanels, and their expected closure times are all standard content.
- •Anterior fontanel closes 12–18 months; posterior closes by 2–3 months
- •First void within 24 hours, first meconium stool within 24–48 hours
- •Weight loss of up to 10% in the first week is expected
- •Periodic breathing with pauses under 20 seconds is normal; apnoea over 20 seconds is not
- •Acrocyanosis normal; circumoral or central cyanosis is reported
- •Positive Babinski and a symmetrical Moro reflex are expected findings
Reflexes and neurological assessment
Primitive reflexes indicate neurological integrity, and the exam asks both which reflexes should be present and when they disappear. The Moro or startle reflex, elicited by a sudden change in position, produces symmetrical abduction and extension of the arms followed by flexion, and disappears around four to six months; an asymmetrical Moro suggests clavicle fracture or brachial plexus injury.
Rooting and sucking support feeding and fade by three to four months and around one year respectively. The palmar grasp disappears around three to four months and the plantar grasp around eight months. The tonic neck or fencing reflex disappears by three to four months. The stepping reflex fades by about four weeks, and Babinski — fanning of the toes — remains positive until roughly one year, when a flexor response replaces it.
Neurological red flags include a high-pitched shrill cry, jitteriness that does not stop when the limb is held, a bulging or markedly sunken fontanel, absent or asymmetrical reflexes, seizure activity such as lip smacking or eye deviation, and marked hypotonia. Jitteriness in a newborn should always prompt a blood glucose check, because hypoglycaemia is the most common treatable cause.
Thermoregulation, glucose and jaundice
Newborns lose heat through convection, conduction, radiation and evaporation, and they cannot shiver. Non-shivering thermogenesis burns brown fat, which consumes glucose and oxygen and produces acid, so cold stress leads directly to hypoglycaemia, metabolic acidosis and respiratory distress. Prevention answers are practical: dry immediately, remove wet linen, apply a hat, use skin-to-skin contact or a radiant warmer, delay the first bath until temperature is stable, warm surfaces before contact and keep the cot away from windows and drafts.
Hypoglycaemia is defined by facility protocol, commonly a glucose below forty to forty-five milligrams per decilitre in the first hours. Infants of diabetic mothers, preterm, small or large for gestational age infants and those with cold stress are at risk. Signs are jitteriness, poor feeding, lethargy, temperature instability, a weak cry, apnoea and seizures. Early feeding and glucose monitoring per protocol are the standard responses.
Jaundice timing determines interpretation. Physiological jaundice appears after twenty-four hours, peaks around day three to five in term infants and reflects immature hepatic conjugation. Pathological jaundice appears within the first twenty-four hours or rises rapidly, and suggests haemolysis such as ABO or Rh incompatibility; it is reported immediately. Phototherapy nursing care includes eye protection, maximal skin exposure with the nappy area covered, temperature monitoring, extra fluid intake, frequent repositioning and observation for loose green stools.
