Nursing Elites

1. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarctation 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 findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.

2. What information should be reinforced with the mother of a child with ringworm (Tinea)?

• A. Ringworm is not contagious.
• B. Tinea infections are indicative of poor hygiene and uncleanliness.
• C. Tinea infections are spread by direct and indirect contact.
• D. Ringworm often subsides spontaneously.

Correct answer: C

Rationale: The correct answer is C. Ringworm, a fungal infection, is highly contagious and can be spread by direct contact with infected individuals or animals and indirectly through contaminated objects. It is important for the mother to understand the modes of transmission to prevent the spread of the infection to others and to take necessary precautions to ensure proper treatment and containment of the condition. Choices A and D are incorrect because ringworm is indeed contagious, and it may not always subside spontaneously. Choice B is misleading as tinea infections are not solely indicative of poor hygiene; they can affect anyone, regardless of personal cleanliness.

3. When reinforcing information about the use of corticosteroids in treating asthma in children, which statement indicates that the parent understands the teaching?

• A. My child should take the medication only when experiencing symptoms.
• B. I will rinse my child's mouth after each use of the inhaler.
• C. I should discontinue the medication if my child seems better.
• D. Corticosteroids are used for quick relief during an asthma attack.

Correct answer: B

Rationale: Rinsing the mouth after using corticosteroid inhalers is crucial as it helps prevent oral thrush, a common side effect associated with these medications. This practice reduces the risk of developing fungal infections in the mouth and throat, maintaining optimal oral health during asthma treatment.

4. A 7-year-old is admitted to the hospital with persistent vomiting, and a nasogastric tube attached to low intermittent suction is applied. Which finding is most important for the nurse to report to the healthcare provider?

• A. Gastric output of 100 mL in the last 8 hours.
• B. Shift intake of 640 mL IV fluids plus 30 mL PO ice chips.
• C. Serum potassium of 3.0 mEq/L.
• D. Serum pH of 7.45.

Correct answer: C

Rationale: A serum potassium level of 3.0 mEq/L is significantly low and indicates hypokalemia, which can lead to serious complications such as cardiac arrhythmias. Therefore, it is crucial for the nurse to report this finding promptly to the healthcare provider for immediate intervention. The other findings are not as critical in this situation. Gastric output of 100 mL in the last 8 hours may be expected in a patient with persistent vomiting. The shift intake of IV fluids and ice chips indicates fluid replacement, which is important but not as urgent as correcting electrolyte imbalances. A serum pH of 7.45 is within the normal range and does not indicate an immediate concern.

5. A 6 year old who has asthma is demonstrating a prolonged expiratory phase and wheezing and has a 35% of personal best peak expiratory flow rate (PEFR). Based on these findings, what actions should the nurse take first?

• A. Administer a prescribed bronchodilator.
• B. Encourage the child to cough and deep breath.
• C. Report findings to the health care provider.
• D. Determine what triggers precipitated this attack.

Correct answer: A

Rationale: Administering a bronchodilator will help open the airways and improve breathing.
