A nurse is caring for a client who has heart failure and a prescription for digoxin 125 mcg PO daily. Available is digoxin PO 0.25 mg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
Let's convert the digoxin dosage from mcg (micrograms) to mg (milligrams) and then divide it by the amount of digoxin per tablet to find out how many tablets are needed.
Steps to solve:
- Convert digoxin dose from mcg to mg:
- We know 1 mg is equal to 1000 mcg.
- Digoxin dose (mg) = Digoxin dose (mcg) / 1000 mcg/mg
- Digoxin dose (mg) = 125 mcg / 1000 mcg/mg
- Digoxin dose (mg) = 0.125 mg
- Calculate the number of tablets required:
- Number of tablets = Digoxin dose (mg) / Digoxin per tablet (mg)
- Number of tablets = 0.125 mg / 0.25 mg/tablet
Since the result is 0.5, we need to round to the nearest tenth.
Answer: The nurse should administer 0.5 tablets per dose.

Correct Answer is C
Explanation
A. Activate the fire alarm: While activating the fire alarm is important in alerting others to the fire, the priority is ensuring the safety of clients in the immediate vicinity. Moving clients away from the potential danger takes precedence over activating the alarm.
B. Use a fire extinguisher to put out the fire: While extinguishing the fire is necessary to prevent its spread, it should only be attempted after ensuring the safety of clients nearby. Attempting to use a fire extinguisher without first moving clients could put them at risk of injury or smoke inhalation.
C. Move any clients in the immediate vicinity: This is the priority action. Moving clients away from the potential danger of the smoldering fire helps protect them from smoke inhalation and potential burns. It ensures their safety while allowing the nurse to assess the situation and determine further actions.
D. Close the fire doors on the unit: Closing fire doors can help contain the fire and prevent its spread, but it is not the immediate priority when clients are in close proximity to the smoldering fire. Moving clients to safety should be the first action taken.
Correct Answer is A
Explanation
A. Clear the respiratory tract: This is the correct action. Clearing the newborn's respiratory tract is the priority immediately after delivery to ensure adequate breathing. The nurse should suction the mouth and nose with a bulb syringe to remove any mucus or amniotic fluid and facilitate effective respiration.
B. Cut the umbilical cord: Cutting the umbilical cord is an important step in newborn care, but it is typically done after ensuring the newborn's immediate respiratory needs are met. The priority immediately after delivery is to establish effective breathing.
C. Stimulate the infant to cry: While stimulating the infant to cry can help clear the airways and establish effective breathing, it should be done concurrently with clearing the respiratory tract. Therefore, clearing the respiratory tract takes precedence over stimulating the infant to cry.
D. Dry the infant off and cover the head: Drying the infant and covering the head are important steps in newborn care to prevent heat loss and maintain thermal regulation. However, these actions can be done after ensuring the newborn's respiratory tract is clear and breathing is established.
