Question 1

If an infant presents with a Macewen sign-also known as the cracked pot sign-in which an obvious enlarged venous system appears on the top of the head, what medical condition should be suspected?&#10;A) Cerebral bleed&#10;B) Abusive head trauma&#10;C) Meningitis&#10;D) Increased intracranial pressure

Accepted Answer

Macewen sign, or the cracked pot sign, is indicative of increased intracranial pressure, often seen in conditions such as hydrocephalus. It is characterized by a specific sound heard when tapping the skull near the junction of the frontal, parietal, and occipital bones, suggesting abnormal separation of sutures due to pressure.

Question 2

A child presents with a Pediatric Glasgow Coma Scale score of 7. As a pediatric nurse, what does this score indicate?&#10;A) The patient is neurologically intact.&#10;B) The patient requires intubation.&#10;C) The patient is in a coma.&#10;D) The patient is brain dead.

Accepted Answer

The Pediatric Glasgow Coma Scale is used to assess the level of consciousness in children. A score of 7 indicates that the patient is in a coma, as scores of 8 or below are generally considered to reflect a comatose state.

Question 3

If you were asked to assess the afferent fibers of cranial nerves V and IX and the efferent fibers of cranial nerves VII, IX, and XII, which primitive reflex should be assessed?&#10;A) Moro reflex&#10;B) Startle reflex&#10;C) Sucking reflex&#10;D) Babinski reflex

Accepted Answer

The sucking reflex involves the assessment of afferent fibers of cranial nerves V (trigeminal) and IX (glossopharyngeal) for sensation and efferent fibers of cranial nerves VII (facial), IX (glossopharyngeal), and XII (hypoglossal) for the motor response of sucking, making it the correct choice for evaluating these specific cranial nerve functions.

Question 4

If a child presents with excessive head growth and increased intracranial pressure, which method could be used to determine the etiology of this condition?&#10;A) Spinal tap&#10;B) Ventricular tap&#10;C) Electromyography&#10;D) Positron emission tomography

Accepted Answer

A ventricular tap can help determine the cause of increased intracranial pressure by analyzing cerebrospinal fluid and relieving pressure, which can provide diagnostic information about conditions like hydrocephalus.

Question 5

When caring for a child who just underwent a lumbar puncture procedure, what action should be taken so the child does not suffer from a post-procedure spinal headache?&#10;A) Encourage the child to drink fluids&#10;B) Maintain the child in supine position&#10;C) Maintain the child in fetal position&#10;D) Maintain thechild in Trendelenburg position

Accepted Answer

The answer of When caring for a child who just...

Question 6

When performing an assessment on a child, you notice "flame-like" hemorrhages of the retina, bleeding in the optic nerve, and swelling of the eye structures. These findings will confirm what diagnosis?

A) Cerebral bleed
B) Abusive head trauma
C) Meningitis
D) Increased intracranial pressure

Accepted Answer

The described symptoms, including "flame-like" hemorrhages of the retina, bleeding in the optic nerve, and swelling of the eye structures, are indicative of abusive head trauma, formerly known as shaken baby syndrome. These findings are associated with violent shaking and the impact on the brain and eye structures.

Question 7

For which of the following medical conditions is it important for the healthcare team to collect blood cultures and cerebrospinal fluid via lumbar puncture prior to administering antibiotic therapy?&#10;A) Cerebral palsy&#10;B) Muscular dystrophy&#10;C) Meningitis&#10;D) Guillain-Barre syndrome

Accepted Answer

Meningitis is an infection of the protective membranes covering the brain and spinal cord, which can be caused by bacteria, viruses, or other microorganisms. Blood cultures and cerebrospinal fluid (CSF) obtained via lumbar puncture are essential for identifying the causative agent and guiding appropriate antibiotic therapy. This is crucial to ensure the effectiveness of treatment and to prevent potential complications.

Question 8

Medical treatments for bacterial meningitis consist of the rapid initiation of antibiotic therapy. Which medications may be used on a trial basis to reduce inflammation and prevent complications such as hearing loss?

A) Corticosteroids
B) Selective serotonin reuptake inhibitors
C) Antihistamines
D) Loop diuretics

Accepted Answer

Corticosteroids are often used on a trial basis to reduce inflammation and prevent complications such as hearing loss in the treatment of bacterial meningitis. They can help to decrease the inflammatory response around the brain and spinal cord.

Question 9

If a child with a brain tumor presents with back pain or pain that extends from the back out to the arms or down the legs, what should be suspected?&#10;A) Cerebral bleed&#10;B) Cerebrospinal fluid leak&#10;C) Increased intracranial pressure&#10;D) Spinal metastases

Accepted Answer

Spinal metastases should be suspected if a child with a brain tumor presents with back pain or pain that radiates from the back to the arms or legs, as this indicates the tumor may have spread to the spinal area.

Question 10

HLA testing may be suggested for children with seizure disorders in higher-risk ethnic groups. Children who test positive for the HLA-B*1502 allele should not take which common anti-seizure medication because of their increased risk of developing Stevens-Johnson syndrome?

A) Carbamazepine
B) Clonazepam
C) Phenobarbital
D) Phenytoin

Accepted Answer

Carbamazepine is associated with an increased risk of Stevens-Johnson syndrome in individuals who test positive for the HLA-B*1502 allele, particularly in certain Asian populations. This genetic testing can help guide safer medication choices for those with seizure disorders.
