Ten hours following thrombolysis for an ST elevation myocardial infarction (STEMI), a client is receiving a lidocaine infusion for isolated runs of ventricular tachycardia (VT). Which finding should the nurse document in the electronic medical record as a therapeutic response to the lidocaine infusion?
- A. Stabilization of blood pressure ranges
- B. Cessation of chest pain
- C. Reduce heart rate
- D. Decreased frequency of episodes of VT
Correct Answer: D
Rationale: Lidocaine is used to suppress ventricular tachycardia, so a decrease in episodes indicates a therapeutic response.

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.
The nurse is closely monitoring the intake and output of an infant with heart failure who is receiving diuretic therapy. The nurse should use which most appropriate method to assess urine output?

The parent of a 1-year-old child with tetralogy of Fallot asks the nurse, “Why do my child’s fingertips look like that?†On what understanding does the nurse base a response?
- A. Clubbing occurs as a result of untreated congestive heart failure.
- B. Clubbing occurs as a result of a left-to-right shunting of blood.

Correct Answer: D
Rationale: Clubbing of the fingers develops in response to chronic hypoxia.
Recognised features of ABO incompatibility include:
- A. Normal haemoglobin on day 1
- B. Worsening with subsequent pregnancies
- C. Conjugated hyperbilirubinaemia
- D. Negative Coombs test
Correct Answer: A
Rationale: In ABO incompatibility, haemoglobin levels are typically normal on day 1. The condition does not worsen with subsequent pregnancies and is associated with unconjugated hyperbilirubinaemia.
