1. The healthcare provider is preparing to administer digoxin (Lanoxin) to a 6-month-old infant with heart failure. The healthcare provider notes that the infant’s heart rate is 90 beats per minute. What should the healthcare provider do next?

• A. Administer the medication as prescribed
• B. Hold the medication and notify the healthcare provider
• C. Reassess the heart rate in 30 minutes
• D. Administer half the prescribed dose

Correct answer: B

Rationale: In this scenario, the correct action is to hold the medication and notify the healthcare provider. Digoxin should be withheld if the infant’s heart rate is below 100 beats per minute. Administering digoxin in this situation can further slow down the heart rate in infants with heart failure, leading to potential adverse effects. Reassessing the heart rate in 30 minutes is not the best immediate action to take, as prompt notification and withholding of the medication are crucial. Administering the medication as prescribed or giving half the dose can exacerbate the situation by potentially further lowering the heart rate.

2. A toddler with a chronic illness that requires frequent hospitalization is likely to experience which psychosocial developmental challenge?

• A. Fixation with feelings of inadequacy
• B. Interference with the development of autonomy
• C. Distortion of differentiation of self from parent
• D. Delayed language, fine-motor, and self-care skills

Correct answer: B

Rationale: Toddlers with chronic illnesses requiring frequent hospitalization may experience interference with the development of autonomy. This is because the need for constant medical care can restrict their independence and ability to explore and make choices, which are essential aspects of achieving autonomy according to Erikson's stages of psychosocial development. Choices A, C, and D are incorrect. Fixation with feelings of inadequacy (Choice A) is more commonly associated with Erikson's stage of industry vs. inferiority in middle childhood. Distortion of differentiation of self from parent (Choice C) is related to the separation-individuation phase of Mahler's theory of object relations, typically occurring in infancy. Delayed language, fine-motor, and self-care skills (Choice D) may be impacted by chronic illness but are not the primary psychosocial developmental challenge faced by toddlers in this context.

3. The heart rate for a 3-year-old with a congenital heart defect has steadily decreased over the last few hours, now it's 76 bpm, the previous reading 4 hours ago was 110 bpm. Which additional finding should be reported immediately to a healthcare provider?

• A. Oxygen saturation 94%.
• B. RR of 25 breaths/minute.
• C. Urine output 20 mL/hr.
• D. BP 70/40.

Correct answer: D

Rationale: A significant drop in heart rate and blood pressure should be reported immediately as it may indicate worsening of the congenital heart defect. A decrease in blood pressure may suggest poor cardiac output and compromised perfusion, requiring urgent medical attention. The other findings (oxygen saturation of 94%, RR of 25 breaths/minute, and urine output of 20 mL/hr) are within normal ranges for a 3-year-old and do not indicate immediate deterioration of the heart defect.

4. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

• A. The aortic semilunar valve obstructs blood flow into the systemic circulation
• B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
• C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
• D. An opening in the atrial septum causes a murmur due to a turbulent left-to-right shunt

Correct answer: B

Rationale: The correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.

5. A 9-week-old infant is scheduled for cleft lip repair. Which information is most important for the nurse to convey to the surgeon before transporting the infant to the surgical suite?

• A. Red blood cell count of 2.3 million/mm³
• B. White blood cell count of 10,000/mm³
• C. Weight gain of 2 pounds since birth
• D. Urine specific gravity is 1.011

Correct answer: A

Rationale: The correct answer is A because a low red blood cell count may indicate anemia, which could pose risks during surgery. Anemia can affect oxygen delivery to tissues, impacting wound healing and overall surgical outcomes. The other options, such as white blood cell count, weight gain, and urine specific gravity, are less critical for immediate surgical considerations. White blood cell count is more related to infection risk postoperatively rather than immediate surgical risk. Weight gain reflects good overall growth but does not impact the immediate surgical situation. Urine specific gravity is more indicative of hydration status rather than immediate surgical risk.
