• Each numbered entry focuses on one tested pediatric nursing concept and the clinical logic behind it.
• ANSWER TO KNOW gives the key takeaway. WHY explains the rationale. QUESTION HINT highlights the clue pattern.
DON'T CONFUSE IT WITH separates the concept from a common distractor.
• Concepts were consolidated across the supplied pediatric review sets. Exact duplicate questions were not intentionally
repeated; similar concepts were retained when they tested a different answer, action, manifestation, or clinical angle.
• This guide paraphrases and organizes study concepts rather than reproducing a proprietary exam. Source items that
were incomplete or internally uncertain were not used to invent missing details.
1 | Respiratory Distress in an Infant: Follow-Up Findings
ANSWER TO KNOW: Substernal/subcostal retractions, tachypnea, low oxygen saturation, and poor intake/dehydration
require follow-up.
WHY: Retractions indicate increased work of breathing. Tachypnea and decreased oxygenation point to respiratory
compromise, while poor intake and decreased urine output can indicate dehydration.
QUESTION HINT: Infant + retractions + fast respirations + falling oxygen saturation = respiratory status moves to the front
of the line.
DON'T CONFUSE IT WITH: Do not dismiss poor feeding or decreased wet diapers as merely behavioral when they
accompany respiratory illness.
2 | Pediatric IV Therapy: Choosing a Catheter
ANSWER TO KNOW: Use the smallest appropriate peripheral IV catheter; a 24-gauge catheter is appropriate for a young
infant when adequate for the prescribed therapy.
WHY: Small pediatric veins are vulnerable to trauma. A smaller catheter can provide needed access while reducing vessel
injury.
QUESTION HINT: Infant IV question = think smallest gauge that safely delivers the ordered therapy.
DON'T CONFUSE IT WITH: Do not choose a larger catheter simply because antibiotics are being administered.
3 | Fractures: Compartment Syndrome
ANSWER TO KNOW: Monitor a child with multiple closed fractures for compartment syndrome.
WHY: Bleeding and edema within a confined fascial compartment can raise pressure, impair circulation and nerve
function, and threaten the extremity.
QUESTION HINT: Fracture + escalating pain/swelling/neurovascular change = compartment syndrome.
DON'T CONFUSE IT WITH: Volkmann ischemic contracture is a possible consequence of prolonged ischemia, not the
early complication you are trying to detect.
4 | Hemophilia: Safer Physical Activity
ANSWER TO KNOW: Choose low-impact activity with minimal risk for trauma, such as bowling.
WHY: Hemophilia increases bleeding risk. Activities with lower collision and fall risk reduce the chance of joint and soft-
tissue bleeding.
QUESTION HINT: Hemophilia + sports = avoid collision/contact and high-fall-risk activities.
DON'T CONFUSE IT WITH: Basketball, soccer, and gymnastics carry substantially more trauma risk.
5 | Pediatric Stroke: Sudden Neurologic Deficits
ANSWER TO KNOW: Treat sudden unilateral weakness, slurred speech, confusion, visual changes, or gait disturbance as
an acute neurologic emergency.
WHY: Focal deficits after a procedure such as cardiac catheterization can indicate acute cerebral ischemia or another
serious neurologic complication.
QUESTION HINT: Sudden one-sided weakness + speech/vision change = stroke pattern.
DON'T CONFUSE IT WITH: Do not attribute an abrupt focal deficit to fatigue, sedation, or normal recovery.
6 | Acute Poststreptococcal Glomerulonephritis: Management
ANSWER TO KNOW: Monitor blood pressure, daily weight, urine output/protein, and use sodium/fluid restriction or
prescribed antihypertensive/diuretic therapy as indicated.
WHY: Poststreptococcal glomerular inflammation causes hematuria, edema, reduced urine output, sodium and water
retention, and hypertension.
QUESTION HINT: Recent strep + cola/brown urine + periorbital edema + hypertension = APSGN.
2026 PEDIATRIC NURSING CMS REVIEW • Independent study resource
, DON'T CONFUSE IT WITH: Do not confuse APSGN with nephrotic syndrome, which is dominated by massive proteinuria
and hypoalbuminemia.
7 | Crohn Disease: Malnutrition
ANSWER TO KNOW: Persistent diarrhea plus poor intake and low nutrient markers can indicate malnutrition.
WHY: Crohn disease can impair absorption and intake. Ongoing diarrhea adds fluid and nutrient losses.
QUESTION HINT: Crohn + chronic diarrhea + low iron/B12 or poor intake = nutritional compromise.
DON'T CONFUSE IT WITH: Do not focus only on stool frequency; growth, weight, and micronutrient status matter.
8 | Inhaled Corticosteroids: Preventing Oral Candidiasis
ANSWER TO KNOW: Use a spacer when prescribed and rinse the mouth after inhaled corticosteroids.
WHY: A spacer decreases medication deposition in the mouth and oropharynx, reducing local steroid exposure and
candidiasis risk.
QUESTION HINT: Fluticasone + white oral patches = think local steroid deposition.
DON'T CONFUSE IT WITH: Do not stop the controller medication solely because thrush developed; correct technique and
treatment are the key issues.
9 | Pediculosis Capitis: Home Management
ANSWER TO KNOW: Remove nits with a fine-tooth comb and clean hair-care items appropriately, such as soaking them in
hot/boiling water when instructed.
WHY: Mechanical nit removal and cleaning items that contact the hair help prevent reinfestation.
QUESTION HINT: Head lice = treat the hair + remove nits + deal with combs/brushes.
DON'T CONFUSE IT WITH: Do not repeatedly overuse pediculicide shampoo beyond directions.
10 | Infant Diarrhea: Dehydration
ANSWER TO KNOW: Expect hemoconcentration, including an increased hematocrit, with dehydration.
WHY: Fluid loss decreases plasma volume, concentrating circulating blood cells. Tachycardia and a sunken fontanel can
also occur.
QUESTION HINT: Diarrhea + dehydration = less circulating water, more concentrated labs.
DON'T CONFUSE IT WITH: Polyuria and a bulging fontanel do not fit dehydration.
11 | Influenza: Transmission Precautions
ANSWER TO KNOW: Use droplet precautions.
WHY: Influenza spreads primarily through respiratory droplets produced by coughing, sneezing, and close contact.
QUESTION HINT: Influenza = droplet.
DON'T CONFUSE IT WITH: Airborne precautions are reserved for pathogens transmitted through smaller suspended
particles.
12 | Post-Tonsillectomy Hemorrhage
ANSWER TO KNOW: Frequent or continuous swallowing can indicate postoperative bleeding.
WHY: Blood draining down the posterior pharynx may trigger repeated swallowing even when obvious oral bleeding is
absent.
QUESTION HINT: After tonsillectomy, swallowing over and over = look for bleeding.
DON'T CONFUSE IT WITH: Throat discomfort and altered taste can occur postoperatively, but repeated swallowing is the
red flag.
13 | Systemic Corticosteroids: Growth Suppression
ANSWER TO KNOW: Monitor growth in children receiving long-term systemic corticosteroids.
WHY: Chronic corticosteroid therapy can suppress growth and also cause metabolic effects such as hyperglycemia and
hypertension.
QUESTION HINT: Long-term prednisone + child = watch growth.
DON'T CONFUSE IT WITH: Do not expect hypoglycemia or hypotension as the classic steroid pattern.
14 | Cranial Nerve V: Motor Function
ANSWER TO KNOW: Symmetrical jaw strength when biting down supports intact trigeminal motor function.
WHY: Cranial nerve V supplies muscles of mastication as well as facial sensation.
QUESTION HINT: CN V = face sensation + chewing.
