Congenital cardiac questions become manageable once you sort lesions by what they do to blood flow rather than memorising names. These questions cover cyanotic and acyanotic defects, recognising and responding to a tet spell, the signs of heart failure in an infant, and priorities after cardiac surgery.
Question 1
127 of 150. An 18-year-old with complex congenital heart disease admits they rely entirely on parents for insurance navigation and pharmacy calls. To foster practical independence, which intervention should the nurse implement during today's visit?
- A) Instruct the parents to maintain the current family insurance coverage.
- B) Advise the patient to apply for independent state disability benefits.
- C) Guide the patient through calling the insurance customer service line.✓
- D) Provide a detailed textbook chapter on national healthcare finance laws.
💡 Key Takeaway
Supported, hands-on practice with administrative tasks builds essential healthcare navigation skills for young adults.
Show rationale
Fostering independence in older adolescents requires active, supported practice of administrative healthcare tasks. Option C is correct because guiding the patient through a real-world task like calling insurance builds confidence and practical navigation skills. Option A ignores the patient's need to learn how to manage their own healthcare logistics. Option B may not be medically or financially indicated and does not teach daily navigation skills. Option D is overly academic, overwhelming, and lacks the hands-on application necessary for effective adult learning.
Question 2
150 of 150. A 7-year-old child is being evaluated for a new murmur. The nurse hears a grade II/VI soft, systolic ejection murmur at the left upper sternal border. The nurse also notes a widely split S2 that does not vary with respiration. The child has normal growth parameters.
- A) Conclude this is an innocent pulmonary ejection murmur.
- B) Advise the parents to restrict the child's fluid intake.
- C) Recognize the heart sounds suggest a structural defect.✓
- D) Schedule a routine reassessment at the next annual visit.
💡 Key Takeaway
A widely split S2 that does not vary with respiration indicates a pathologic murmur, often an atrial septal defect.
Show rationale
While a soft systolic ejection murmur can sometimes be innocent, a fixed split S2 that does not vary with respiration is a hallmark sign of an atrial septal defect, making this a pathologic murmur. Recognizing this structural defect is essential for appropriate referral. Concluding this is an innocent murmur (A) is incorrect because an innocent pulmonary flow murmur features a normally splitting S2. Restricting fluid intake (B) is not a standard initial intervention for an undiagnosed, asymptomatic child. Scheduling a routine reassessment at the next annual visit (D) delays necessary diagnostic evaluation for a potential congenital heart defect.
Question 3
45 of 150. A family cannot afford ready-to-feed formula for their 2-month-old infant with a congenital heart defect. The nurse instructs them on preparing powdered formula to minimize the risk of Cronobacter sakazakii infection. Which preparation step is essential for this infant?
- A) Freeze the powdered formula for two hours prior to mixing.
- B) Boil the prepared formula mixture for five minutes before cooling.
- C) Use distilled room temperature water to mix the powdered formula.
- D) Mix the powder using water heated to 158 degrees Fahrenheit.✓
💡 Key Takeaway
High-risk infants require powdered formula mixed with water heated to 158°F to kill Cronobacter.
Show rationale
For infants under three months or those with compromised immune systems, powdered formula should be mixed with water heated to at least 158°F (70°C) to kill potential Cronobacter bacteria present in the non-sterile powder. Option B is incorrect because boiling the actual formula degrades essential nutrients and vitamins. Option C is incorrect as room temperature water, even if distilled, will not eliminate bacteria residing in the powder itself. Option A is incorrect because freezing does not reliably destroy Cronobacter spores.
Question 4
54 of 150. A 6-week-old infant exhibits poor weight gain despite breastfeeding every two hours. The mother notes the infant sweats profusely during feedings and often falls asleep after five minutes of nursing. The physical exam is otherwise unremarkable. Which etiology best explains this presentation?
- A) Non-organic failure to thrive from poor maternal attachment
- B) Organic failure to thrive from increased metabolic demands✓
- C) Non-organic failure to thrive from inadequate breastmilk supply
- D) Organic failure to thrive from gastrointestinal malabsorption issues
💡 Key Takeaway
Diaphoresis and rapid fatigue during infant feedings are classic signs of organic failure to thrive from cardiac disease.
Show rationale
The infant's symptoms of sweating profusely during feedings and rapid fatigue are classic signs of congenital heart disease or heart failure, which cause increased metabolic demands and inadequate caloric intake. This represents an organic cause of failure to thrive. Poor maternal attachment and inadequate breastmilk supply represent non-organic causes, but they do not typically cause diaphoresis or rapid exhaustion during feeds. Gastrointestinal malabsorption is an organic cause, but it typically presents with chronic diarrhea, vomiting, or abnormal stools rather than isolated fatigue and sweating during exertion.
Question 5
123 of 150. You are monitoring a 6-month-old with tetralogy of Fallot who suddenly develops a heart rate of 210 and profound cyanosis. During your SBAR communication with the cardiologist, which statement best represents the "Assessment" phase?
- A) The infant is a six-month-old admitted with tetralogy of Fallot.
- B) The infant is currently experiencing a severe hypercyanotic tetralogy spell.
- C) I need you to come evaluate this infant right away.
- D) I think the infant is developing uncompensated cardiogenic shock rapidly.✓
💡 Key Takeaway
The assessment phase of SBAR requires the nurse to synthesize clinical data into a professional judgment about the patient's status.
Show rationale
The "Assessment" phase is where the nurse provides their critical thinking and synthesis of the situation, rather than just listing facts. Option D is the correct answer because it translates the clinical cues (tachycardia, cyanosis) into a synthesized clinical judgment of uncompensated cardiogenic shock. Option A is the "Background," providing the patient's age and underlying diagnosis. Option B is the "Situation," describing the immediate event occurring at the bedside. Option C is the "Recommendation," stating the desired action from the provider. By clearly articulating the clinical synthesis in the assessment phase, the nurse helps the provider understand the severity of the physiological compromise.
Question 6
50 of 150. A 3-month-old with a prolonged PICU stay for congenital heart disease begins averting their gaze and hiccuping during a nursing assessment. Which intervention is most appropriate?
- A) Initiate a rapid response for impending acute respiratory failure.
- B) Decrease environmental stimuli by dimming lights and lowering noise.✓
- C) Administer a scheduled dose of oral liquid pain medication.
- D) Increase the flow rate of the ordered supplemental oxygen.
💡 Key Takeaway
Gaze aversion and hiccuping in infants are behavioral signs of sensory overload requiring environmental modification.
Show rationale
A 3-month-old experiencing a prolonged PICU stay is highly susceptible to sensory overload. Averting gaze and hiccuping are classic infant stress cues indicating overstimulation. Reducing environmental noise and light helps soothe the infant and supports neurodevelopment. Option A is incorrect because these are behavioral stress cues, not signs of impending respiratory failure. Option C is incorrect because there is no specific indication of pain, and analgesics do not treat sensory overload. Option D is incorrect because oxygen therapy does not address the environmental overstimulation causing the stress behaviors.
Question 7
71 of 150. You are providing prenatal counseling to parents following a prenatal diagnosis of Down syndrome. When discussing the importance of postnatal cardiac screening, you explain that the most common congenital heart defect associated with this genetic condition is:
- A) Tetralogy of Fallot requiring early surgical intervention.
- B) Transposition of the great arteries needing prostaglandins.
- C) Coarctation of the aorta presenting with weak pulses.
- D) Atrioventricular septal defect causing early heart failure.✓
💡 Key Takeaway
Complete atrioventricular septal defect (AVSD) is the most prevalent congenital heart defect in children with Down syndrome.
Show rationale
Nearly half of all children born with Down syndrome have some form of congenital heart disease. The most frequently encountered anomaly is a complete atrioventricular septal defect (AVSD), which accounts for a significant portion of these cases and often leads to early congestive heart failure as pulmonary resistance falls. Ventricular septal defects (VSDs) and atrial septal defects (ASDs) are also highly prevalent. While Tetralogy of Fallot (option A) does occur more frequently in children with Down syndrome than in the general population, it is far less common than an AVSD. Transposition of the great arteries (option B) and coarctation of the aorta (option C) are not classically associated with Trisomy 21 and occur at rates similar to or lower than those seen in the general pediatric population. Recognizing the specific cardiac risk profile helps guide accurate parental counseling.
Question 8
110 of 150. The father of a 6-month-old with congenital heart disease brings a binder of internet research to the clinic. He asks detailed questions about surgical mortality statistics but misses his infant's feeding cues during the visit.
- A) Validate his research while redirecting to immediate infant needs.✓
- B) Encourage him to continue gathering extensive statistical surgical data.
- C) Recommend he stop reading internet forums to reduce his anxiety.
- D) Schedule a separate consultation to review all his research data.
💡 Key Takeaway
Information-seeking coping is adaptive but requires redirection if it begins to interfere with basic caregiving responsibilities.
Show rationale
The father exhibits information-seeking coping, which gives him a sense of control over a terrifying situation. However, missing feeding cues suggests this behavior is becoming a distraction from present care. Validating his efforts while gently redirecting helps balance his coping strategy with practical parenting. Encouraging more data collection (B) or scheduling a review (D) reinforces the distraction and ignores the infant's immediate needs. Telling him to stop (C) dismisses his primary coping mechanism and could damage the therapeutic relationship.
Question 9
55 of 150. A parent frantically reports their 18-month-old child cried intensely, stopped breathing, turned blue, and briefly fainted after having a toy taken away. The child recovered fully within one minute.
- A) Reassure the parent that this is a benign, expected response.✓
- B) Refer the child for an urgent pediatric neurology consultation.
- C) Instruct the parent to splash cold water during the episode.
- D) Advise the parent to avoid taking toys away moving forward.
💡 Key Takeaway
Cyanotic breath-holding spells are benign, involuntary responses to frustration in toddlers that require parental reassurance.
Show rationale
The scenario describes a classic cyanotic breath-holding spell, which is a relatively common and benign involuntary response to extreme anger or frustration in toddlers. Because the 18-month-old child stopped breathing and turned blue but recovered fully within one minute, the nurse should provide parental reassurance that this is not a seizure or a life-threatening event. Option B is incorrect because a neurology consultation is not indicated for typical breath-holding spells with a clear emotional trigger and rapid recovery. Option C is unnecessary and can be distressing; splashing cold water is an outdated practice that does not prevent the spell. Option D is counterproductive, as parents should not alter necessary limit-setting just to avoid a spell, which would inadvertently reinforce the tantrum behavior.
Question 10
108 of 150. A 6-month-old infant with a ventricular septal defect is receiving bolus nasogastric feedings. The nurse aspirates a large residual volume of undigested formula and notes the infant is tachypneic and diaphoretic with a firm, distended abdomen.
- A) Return the aspirated fluid and administer the feeding.
- B) Discard the aspirated fluid and administer the feeding.
- C) Hold the scheduled feeding and notify the provider.✓
- D) Return the aspirated fluid and decrease the rate.
💡 Key Takeaway
Large gastric residuals accompanied by abdominal distension and respiratory distress require holding feeds and medical evaluation.
Show rationale
The infant is showing clear signs of feeding intolerance and potential respiratory compromise. A large residual volume combined with a firm abdomen and being tachypneic and diaphoretic indicates the stomach is severely overdistended. This overdistension can impair diaphragmatic excursion, which is especially dangerous in an infant with a cardiac defect. Holding the feeding and notifying the healthcare provider is essential for further medical evaluation and to prevent aspiration. Returning the fluid and administering the feeding would exacerbate the abdominal distension and respiratory distress. Discarding the fluid and feeding still adds volume to an already compromised gastrointestinal tract. Returning the fluid and decreasing the rate fails to address the immediate need for medical assessment.
