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 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.
Correct Answer is ["A","B","C","D"]
Explanation
A. Cleanse the skin prior to the procedure: Cleansing the skin before applying the transdermal analgesic cream is essential to remove any dirt, oils, or contaminants that could interfere with its absorption. This step helps ensure optimal drug delivery and effectiveness.
B. Apply the medication an hour before the procedure begins: Applying the transdermal analgesic cream an hour before the procedure allows sufficient time for the medication to be absorbed through the skin and reach its therapeutic effect. This timing ensures that the analgesic properties are in place when the IV insertion procedure starts.
C. Use a visual pain rating scale to evaluate the effectiveness of the treatment: Using a visual pain rating scale can help assess the child's pain level before and after applying the transdermal analgesic cream. This evaluation provides valuable feedback on the cream's effectiveness in providing pain relief.
D. Apply to intact skin: Transdermal medications are designed to be absorbed through intact skin. Applying the cream to intact skin ensures proper absorption and effectiveness of the analgesic medication.
E. Spread the cream over the lateral surface of both forearms. This option might not be necessary or appropriate for the intended purpose. The choice of application site for transdermal analgesic cream depends on the specific medication and the area of pain. While the lateral surface of the forearms can be a suitable site, it may not always be necessary or feasible to apply the cream to both forearms, especially if the intended IV insertion site is on one arm.
