Nursing Elites

1. 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.

2. A two-year-old child with heart failure is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?

• A. Determine the pulse deficit.
• B. Administer the scheduled dose.
• C. Calculate the safe dose range.
• D. Review the serum digoxin level.

Correct answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario as the heart rate of 128 bpm falls within the acceptable range for a two-year-old child with heart failure. It indicates that the child may benefit from the therapeutic effects of digoxin. Monitoring the heart rate closely after administration is essential to ensure the medication's effectiveness and safety. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is within the acceptable range. Calculating the safe dose range (Choice C) is not needed since the heart rate is already within the expected parameters. Reviewing the serum digoxin level (Choice D) is not the immediate action required in this case where the heart rate is within the normal range.

3. When instilling ear drops in a 2-year-old child, how should the practical nurse (PN) position the earlobe to straighten the external auditory canal?

• A. Up and back.
• B. Down and back.
• C. Up and forward.
• D. Down and forward.

Correct answer: B

Rationale: When administering ear drops to a child under three years old, it is essential to pull the earlobe down and back. This positioning helps straighten the external auditory canal, facilitating the proper administration of the ear drops. Pulling the earlobe down and back in young children aims to ensure that the medication reaches the intended area for optimal effectiveness.

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. The mother of a one-month-old calls the clinic to report that the back of her infant's head is flat. How should the nurse respond?

• A. Turn the infant on the left side braced against the crib when sleeping.
• B. Prop the infant in a sitting position with a cushion when not sleeping.
• C. Place a small pillow under the infant's head while lying on the back.
• D. Position the infant on the stomach occasionally when awake and active.

Correct answer: D

Rationale: Positioning the infant on the stomach occasionally when awake and active can help prevent flat spots on the head. This position allows for more natural movement and prevents prolonged pressure on one area of the head, reducing the risk of developing a flat spot. Turning the infant on the left side braced against the crib when sleeping (choice A) is not recommended as it does not address the issue of flat spots. Propping the infant in a sitting position with a cushion when not sleeping (choice B) may increase the risk of falls and is not suitable for a one-month-old. Placing a small pillow under the infant's head while lying on the back (choice C) should be avoided due to the risk of suffocation and sudden infant death syndrome (SIDS).
