Question 1 of 5
A client admitted with gastroenteritis and a potassium level of 2.9 mEq/dL has been placed on telemetry. Which ECG finding would the nurse expect to find due to the client's potassium results?
Correct Answer: A
Rationale: Hypokalemia (2.9 mEq/dL) can cause a depressed ST segment, flattened T waves, and prominent U waves on ECG due to altered cardiac repolarization.
Question 2 of 5
A nursing instructor is preparing a lesson on the dangers of using drugs and alcohol during pregnancy. She would include which of the following as a primary disability associated with children diagnosed with fetal alcohol syndrome?
Correct Answer: A
Rationale: Fetal alcohol syndrome causes primary disabilities like poor motor skills due to neurological damage. Promiscuity, dependency, and depression are not primary effects.

Question 4 of 5
The client is seen in the clinic for treatment of migraine headaches. The drug Imitrex (sumatriptan succinate) is prescribed for the client. Which of the following in the client's history should be reported to the doctor?
Correct Answer: B
Rationale: Prinzmetal's angina is a contraindication for sumatriptan due to the risk of coronary vasospasm, and this should be reported to the doctor.
Question 5 of 5
A client with COPD is in respiratory failure. Which of the following results would be the most sensitive indicator that the client requires a mechanical ventilator?
Correct Answer: C
Rationale: A pH of 7.23 indicates severe respiratory acidosis due to CO2 retention, a sensitive indicator for mechanical ventilation need in COPD. PCO2 and HCO3 are less immediate, and SaO2 is not critical.
