Decreased DLCO is seen with:
- A. Increased CO in circulation
- B. Anaemia

Indomethacin is being given to an infant with a patent ductus arteriosus in an attempt to promote closure of the PDA. The nurse caring for this infant becomes concerned about adverse side effects when noticing:
- A. decreased urine output, decreased platelets, and abdominal distention.
- B. increased blood pressure, tachycardia, and decreased oxygen requirements.
- C. increased urine output, increased white blood cell count, and increased reticulocyte count.
- D. Jaundice, pallor, and a petechial rash
Correct Answer: A
Rationale: Indomethacin can cause renal side effects, including decreased urine output, as well as hematologic effects such as decreased platelets, and gastrointestinal effects like abdominal distention, which are concerning adverse effects in an infant.
Seventy-two hours after cardiac surgery, a young child has a temperature of 101° F. Which action should the nurse take?
- A. Keep child warm with blankets.
- B. Apply a hypothermia blanket.
- C. Record temperature on nurses’ notes.
- D. Report findings to physician.
Correct Answer: D
Rationale: In the first 24 to 48 hours after surgery, the body temperature may increase to 37.7° C (100° F) as part of the inflammatory response to tissue trauma. If the temperature is higher or continues after this period, it is most likely a sign of an infection and immediate investigation is indicated. Blankets should be removed from the child to keep the temperature from increasing. Hypothermia blanket is not indicated for this level of temperature. The temperature should be recorded, but the physician must be notified for evaluation. Suctioning should be done only as indicated, not on a routine basis. The child should be suctioned for no more than 5 seconds at one time. Symptoms of respiratory distress are avoided by using appropriate technique.
In bronchopulmonary dysplasia:
- A. Lung compliance is increased
- B. Bronchial reactivity is increased
- C. Lung function typically improves with age

Correct Answer: D
Rationale: Hyperinflation is a common finding in bronchopulmonary dysplasia due to lung damage and the need for prolonged mechanical ventilation.
The following are examples of acquired heart disease. Select all that apply.
