Questions and Answers

What should the nurse do when nodes are abnormal?

Avoid exploration of the area around the abnormal nodes

Check the area upstream of the abnormal nodes for the source of the problem (correct)

Check the area downstream of the abnormal nodes

Ignore them and focus on other areas

In which four areas of the body are lymph nodes accessible for examination?

Head and neck, arms, breasts, and axillae

Head and neck, arms, inguinal area, and axillae (correct)

Arms, breasts, inguinal area, and legs

Head, breasts, groin, and abdomen

A mother brings her newborn for an assessment and is concerned about the baby's head size. What is true regarding the relative proportions of the head and trunk of a newborn?

At birth, the head is one fifth the total length (correct)

The chest circumference is usually greater than the head circumference at birth

The head size decreases over time in comparison to the trunk size

The head size is not a concern as long as the baby is feeding well

Study Notes

Examination of Abnormal Nodes

Immediate action includes performing further assessments to determine the cause and severity of abnormalities.

Accessible Lymph Node Areas

Cervical (neck) region
Axillary (armpit) region
Inguinal (groin) region
Supraclavicular area (above the collarbone)

Newborn Head Size Concerns

Newborns have larger head proportions relative to their trunk; the head makes up about one-quarter of their total body length.

Function of Soft Spots (Fontanels)

Allow for brain growth and skull flexibility during childbirth and the first year of life.

Responsible Cranial Nerve for Facial Muscles

The facial nerve (Cranial Nerve VII) controls facial muscles; damage can cause asymmetry of palpebral fissures.

Differentiation Between Sharp and Dull Stimulation

Potential damage to the trigeminal nerve (Cranial Nerve V) if a patient cannot differentiate sensations on the face.

Closure of Posterior Fontanel

Typically closes by 2 to 3 months of age.

Asymmetry in Palpebral Fissures

May indicate neurological issues or facial nerve damage.

Purpose of Anterior Fontanel

Facilitates skull expansion for brain growth and eases delivery during birth; typically diamond-shaped.

Head Growth Milestones

A child's head reaches 90% of its final size by age 6.

Closure of Anterior Fontanel

Generally closes by 12 to 18 months of age.

Predominant Growth During Fetal Period

Growth is mainly in head circumference, necessary for brain development.

Enhanced Facial Bones

Enhanced due to growth conditions or genetic factors as children develop.

Noticeability of Facial Bones with Age

Facial bones become more pronounced as the skin loses elasticity and thickness over time.

Changes in Facial Skin with Age

Skin may become thinner, less elastic, and have more wrinkles due to aging.

Nature of Migraine Headaches

Migraines are typically pulsating or throbbing in quality.

Relief Symptoms Associated with Migraines

Often improved by rest or sleep in a quiet, dark environment.

Family History in Headache Types

Migraines frequently have a genetic component, often noted in family histories.

Common Sign of Meningeal Inflammation

Severe headache, often accompanied by other symptoms like neck stiffness and sensitivity to light.

Headaches with Neck Stiffness and Fever

These indicate potential meningitis, a serious condition requiring immediate attention.

Observations During Well-Baby Checkup

Uneven head shape or lack of normal head control can raise concerns.

Trachea Displacement to Unaffected Side

Occurs due to conditions like tension pneumothorax, pushing the trachea away from the affected lung.

Symptoms Suggesting Depressed and Sunken Fontanels

Indicates dehydration or possible cerebral hypovolemia in an infant.

Trachea Pulled to Affected Side

Happens in cases like atelectasis or pleural effusion, where the lung on one side collapses.

Conditions Not Affecting Fontanels

Conditions unrelated to intracranial pressure or fluid status typically do not impact fontanel status.

Causes of Tense or Bulging Fontanels

Often result from increased intracranial pressure due to conditions like hydrocephalus.

Symptoms Suggesting Chronic Nasal Issues in Infants

Chronic watery eyes, sneezing, and clear nasal drainage may indicate allergic rhinitis or nasal congestion.
