Final answer:
The nurse should withhold the digoxin medication and notify the provider if the digoxin level is 0.9 ng/mL or above.
Step-by-step explanation:
The nurse should withhold the medication and notify the provider if the digoxin level is 0.9 ng/mL or above. Digoxin is a medication used to treat heart failure and certain heart rhythm problems. The therapeutic range for digoxin is typically between 0.5-2 ng/mL, so a level of 0.9 ng/mL is within the therapeutic range.
The blood pressure of 142/80 mmHg is slightly elevated, but it is not a contraindication for administering digoxin. Potassium levels of 4.4 mEq/L are within the normal range and do not require withholding digoxin. An apical pulse rate of 52/min is considered within the normal range for an adult, so it does not warrant withholding the medication.
