A nurse is providing postoperative teaching to a client who has a newly inserted pacemaker.
Which of the following statements by the client Indicates that the teaching has been effective?

A. Administering furosemide may also be appropriate for managing heart failure symptoms, but the priority action based on the client's condition is to withhold digoxin.

B. The client's vital signs indicate bradycardia (pulse 52/min), which is a common adverse effect of digoxin, especially in the setting of heart failure. Withholding digoxin is necessary to prevent further exacerbation of bradycardia and potential toxicity.

C. Withholding spironolactone may be considered if there are concerns about electrolyte imbalances, but it is not the priority action in this scenario.

D. Administering ferrous sulfate is not indicated based on the client's chart findings; there is no indication of anemia or iron deficiency.

A. Notifying the facility operator is important, but it is not the immediate priority when there is a fire endangering the client's safety.

B. While closing fire doors can help contain the fire, it is not the priority action after ensuring the client's immediate safety.

C. Turning off oxygen sources is crucial because oxygen can fuel the fire and cause it to spread rapidly. This action helps prevent the fire from worsening.

D. Putting out the fire with the appropriate extinguisher is important, but it comes after ensuring the fire's fuel source is cut off to prevent further escalation of the fire.
