Question 1

Which of the following disorders has been linked to a risk factor for hyperosmolar infusions given to infants too quickly, causing an abrupt rise in systolic blood pressure (BP)?

Accepted Answer

Intraventricular (IVH) and intracranial hemorrhage (ICH)

Answer

Rapid infusion of hyperosmolar solutions in infants can cause a sudden increase in intravascular volume and an abrupt rise in systolic blood pressure. This rapid fluctuation in blood pressure, especially in the immature and fragile cerebral vasculature of infants (particularly premature infants), significantly increases the risk of rupture of delicate blood vessels. This can lead to intraventricular or intracranial hemorrhage, as the sudden pressure changes can overwhelm the brain's autoregulation.

Question 2

Which of the four primary types of cerebral aneurysms is most frequently found in the brain's basilar arteries?

Accepted Answer

Fusiform (giant) aneurysm

Answer

Fusiform aneurysms are characterized by a circumferential dilation of a blood vessel, often appearing as a spindle-shaped bulge, rather than a sac-like protrusion. These types of aneurysms are more commonly found in the basilar arteries and other large vessels at the base of the brain. Their 'giant' designation refers to their size, typically greater than 2.5 cm, and they are often associated with atherosclerosis or dissection.

Question 3

To get a cardiac biopsy, a pediatric patient is getting ready for a cardiac catheterization. Which allergies need to be examined for before performing this procedure on the patient?

Accepted Answer

Iodine or shellfish

Answer

Cardiac catheterization procedures typically involve the use of iodinated contrast dye to visualize the heart chambers and blood vessels. Therefore, it is crucial to assess for allergies to iodine or shellfish, as these indicate a potential hypersensitivity reaction to the contrast agent. An allergic reaction to the contrast dye can range from mild to severe, including anaphylaxis, making pre-procedure screening essential for patient safety.

Question 4

In the pediatric emergency room, an 18-month-old child is identified as having acute laryngotracheobronchitis (LTB). The nurse is getting ready to send the child home after treating and stabilizing the patient. Which at-home remedy should be used, the nurse recommends to the parents?

Accepted Answer

Cool-mist humidifier at bedtime

Answer

Acute laryngotracheobronchitis (LTB), commonly known as croup, causes inflammation and swelling of the airways, leading to a characteristic 'barking' cough and inspiratory stridor. A cool-mist humidifier helps to moisten the inspired air, which can soothe irritated airways and reduce swelling, making it easier for the child to breathe. This simple home remedy provides symptomatic relief by thinning secretions and reducing airway inflammation.

Question 5

During a house fire, firemen find a 6-year-old boy unconscious in his bed; they intubate him, start an intravenous line, and give him fluids. When they take him to the emergency hospital, he has 45% total-body-surface-area (TBSA) burns on his torso and legs.

Which of the following issues is most probable to impact this child?

Accepted Answer

Hypothermia

Answer

A child with 45% total body surface area (TBSA) burns is at significant risk for hypothermia because the skin, which regulates body temperature, is extensively damaged. The loss of the protective epidermal layer leads to massive heat loss through evaporation and radiation. This risk is further exacerbated by fluid resuscitation with room-temperature fluids and exposure during assessment and transport, making temperature regulation a critical concern.
