A client with atrial fibrillation receives a prescription for a loading dose of digoxin 0.5 mg PO. The medication is available in 125 mcg tablets. How many tablets should the nurse administer? (Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["4"]

Convert mg to mcg: 1 mg = 1000 mcg, so 0.5 mg = 0.5 x 1000 = 500 mcg

Divide the desired dose by the tablet strength: 500 mcg / 125 mcg/tablet = 4 tablets

So, the nurse should administer 4 tablets.

Correct Answer is C

Explanation

A. Ensure the client's environment is properly cleaned and disinfected is important, but the priority action is to prevent the spread of MRSA, which is highly contagious. Contact precautions should be initiated immediately to reduce the risk of transmission to others, including healthcare staff and visitors.

B. Reapply sterile non-adhesive dressing is necessary for wound care, but it is not the most important action in this scenario. Ensuring the appropriate precautions are taken to prevent the spread of MRSA is the priority.

C. Initiate contact precautions is the most important action. MRSA is a highly contagious bacterial infection that can spread easily through contact with contaminated surfaces or individuals. By initiating contact precautions, the nurse helps to protect other patients, staff, and visitors from exposure to MRSA.

D. Teach family members how to prevent transmission of infection is important but should be done after the immediate infection control measures, such as initiating contact precautions, have been implemented. Family education can occur once the proper isolation procedures are in place.

A. Irrigate the nasogastric tube with water. B. Elevate the head of bed 45 degrees. C. Review the advanced directive document. D. Perform oropharyngeal suctioning.

Correct Answer is D

Explanation

A. Irrigate the nasogastric tube with water may be necessary if the tube is clogged, but it does not address the immediate concern of the client choking. The priority is ensuring the client’s airway is clear.

B. Elevate the head of bed 45 degrees is a useful intervention for reducing aspiration risk, but it does not address the immediate need to clear the airway when the client is choking. Elevating the head of the bed could be helpful after the airway is cleared.

C. Review the advanced directive document is important for understanding the client’s wishes, but the immediate priority is addressing the choking. The nurse should focus on clearing the airway first, then review the advanced directive as appropriate.

D. Perform oropharyngeal suctioning is the most appropriate action. The client is vomiting and choking, which suggests a risk of airway obstruction. Oropharyngeal suctioning will help clear the airway and prevent aspiration, which is the priority in this situation.
