A nurse in a pediatric clinic is preparing a child diagnosed with intussusception for a
prescribed barium enema. What is the primary therapeutic purpose of performing this
diagnostic procedure prior to considering surgical intervention?
a. To evacuate impacted fecal material from the lower bowel
b. To reduce the invaginated segment of the intestine through hydrostatic pressure
c. To identify the presence of diverticular disease within the colon
d. To visualize the area of esophageal atresia or tracheoesophageal fistula
✔️ Correct Answer: B
Rationale:
Intussusception is a condition in which one portion of the intestine telescopes or
invaginates into an adjacent segment, causing mechanical bowel obstruction that most
commonly affects children between 3 months and 5 years of age. Nonsurgical
management is attempted using hydrostatic pressure from a barium or air enema, which
often successfully reduces the intussuscepted bowel segment (Option B), thereby
eliminating the need for surgical intervention. While a barium enema may incidentally
evacuate feces (Option A), this is not the therapeutic goal in intussusception. This
,diagnostic tool may be used to detect diverticula (Option C) in other clinical contexts,
but that is not its purpose in this scenario. Esophageal atresia (Option D) is not
visualized with a barium enema; this condition requires different diagnostic imaging
studies.
A nurse is providing discharge education to an adolescent female client who has been
prescribed a Milwaukee brace for the management of scoliosis. Which instruction
should the nurse prioritize when teaching this client about brace usage?
a. Remove the brace for one hour each day to allow for bathing and skin care only
b. Remove the brace only when performing prescribed back range-of-motion exercises
c. Wear the brace directly against bare skin to ensure optimal fit and effectiveness
d. Understand that consistent brace wear will permanently cure the spinal curvature
✔️ Correct Answer: A
Rationale:
The Milwaukee brace is an orthotic device designed to slow the progression of spinal
curvature during the adolescent growth spurt rather than to correct existing curvature.
The brace should be worn for 23 hours daily, with a total of one hour removed per day
for hygiene purposes, including bathing and skin assessment (Option A). There are no
specific range-of-motion exercises for the back that require removal of the brace
(Option B). A cotton T-shirt should be worn beneath the brace to protect the skin from
friction and pressure-related breakdown (Option C). The brace does not cure scoliosis
but rather aims to slow curvature progression (Option D).
A nurse is educating the parents of a child with a cyanotic congenital heart defect about
emergency management during a hypercyanotic spell. Which action should the nurse
instruct the parents to perform when a hypercyanotic episode occurs?
a. Position the child flat with the head down and knees elevated above heart level on
pillows
b. Place the child in a right-side-lying position with the head elevated on one pillow
c. Allow the child to assume a knee-chest position with the head and chest slightly
elevated
,d. Encourage the child to sit upright at a 45-degree angle and drink cold water while
taking deep breaths
✔️ Correct Answer: C
Rationale:
A hypercyanotic or "tet" spell is characterized by a sudden decrease in pulmonary blood
flow and increased right-to-left shunting, resulting in profound cyanosis and hypoxia.
The knee-chest position with the head and chest slightly elevated (Option C) increases
systemic vascular resistance, which reduces the right-to-left shunt and improves
pulmonary blood flow, thereby restoring hemodynamic equilibrium. Positioning the
child flat with knees elevated (Option A) or on the right side (Option B) does not achieve
the same hemodynamic effect. Encouraging the child to sit upright and drink cold water
(Option D) may trigger a vasovagal response or exacerbate the spell and is
contraindicated.
During a routine school screening examination, a nurse performs an otoscopic
assessment of a child's ear and notes a tympanic membrane that appears pearly gray, is
slightly bulging, and demonstrates decreased mobility. Based on these objective
findings, what is the nurse's most appropriate action?
a. Document the findings as normal for a school-aged child and take no further action
b. Ask the child about recent upper respiratory symptoms, nasal discharge, or ear pain
c. Send a note home advising the parents to schedule an evaluation with their
healthcare provider
d. Contact the parents and recommend that the child be picked up from school
immediately
✔️ Correct Answer: B
Rationale:
The nurse requires additional assessment data to interpret these otoscopic findings
accurately (Option B). While the tympanic membrane is normally pearly gray, it should
not be bulging, and it should move when the child blows against resistance or when a
small puff of air is introduced into the ear canal. These findings are not completely
normal; therefore, further history and symptom assessment are essential to determine
the clinical significance. Based solely on the otoscope examination findings,
documentation without action (Option A), referral without further assessment (Option
C), and sending the child home (Option D) are not indicated without obtaining
additional clinical information.
, A newborn female infant born to an HIV-positive mother is scheduled for her first
follow-up assessment. If the child has contracted HIV through vertical transmission,
which initial clinical manifestation is she most likely to exhibit?
a. Shortness of breath and tachypnea
b. Joint pain and swelling
c. Persistent upper respiratory infection or cold symptoms
d. Hepatosplenomegaly and lymphadenopathy
✔️ Correct Answer: C
Rationale:
Respiratory tract infections are common in the pediatric population; however, children
with HIV/AIDS have impaired immune defenses against these common pathogens. The
most typical presenting symptom in a child who acquired HIV through vertical
transmission (from mother during delivery) is a persistent cold or respiratory infection
(Option C). Shortness of breath (Option A), joint pain (Option B), and organomegaly
(Option D) are manifestations of AIDS-related complications that typically occur later as
the disease progresses and immunodeficiency worsens.
A child hospitalized for a minor surgical procedure develops a varicella (chickenpox)
infection. Which nursing intervention should the nurse implement first to prevent
transmission within the healthcare setting?
a. Place a surgical mask on the child before transporting outside the room
b. Immunize exposed family members with the varicella vaccine
c. Place the child in strict isolation to prevent an outbreak on the unit
d. Determine which staff members have had varicella before making assignments
✔️ Correct Answer: C
Rationale:
Varicella is communicable from 2 days before the rash appears until all lesions have
crusted; the virus is transmitted through direct contact with vesicular fluid or indirect
contact through airborne respiratory droplets. Strict isolation precautions (Option C) are
indicated immediately to prevent further exposure to staff and other clients. While
identifying staff immunity (Option D) is important for assignment planning, it is a
secondary action after establishing isolation. Placing a mask on the child (Option A) is
