The nurse is caring for the client with cardiac and renal disease. The client now has a serum potassium level of 6.0 mEq/L. Which medications, if prescribed, should the nurse administer? Select all that apply.

A. Raise the bed to a comfortable height:
Raising the bed to a comfortable height is essential for proper body mechanics and preventing back strain. It ensures the nurse can perform the procedure efficiently and safely.

B. Stand on the left side of the bed:
While a left-handed nurse might prefer to stand on the left side for better access, this choice depends on the room layout and client position. Standing on the side where the nurse is most comfortable is essential, but it is not the primary action compared to ensuring proper bed height.

C. Raise the side rail on the working side of the bed:
Raising the side rail on the working side of the bed could obstruct the nurse's access to the client and is not generally recommended during procedures requiring close access to the client.

D. Use the non-dominant hand to insert the catheter:
The dominant hand, in this case, the left hand, should be used to insert the catheter for better control and precision. The non-dominant hand is typically used to hold the genitalia and provide stability.

B. Post NO SMOKING signs in a prominent location in the home:
Oxygen supports combustion, making smoking or exposure to open flames highly dangerous in an oxygen-enriched environment. Posting NO SMOKING signs serves as a reminder to everyone in the household to avoid smoking or using open flames near the oxygen source.

C. Notify local fire department:
It's crucial to inform the local fire department that a client is using home oxygen therapy. This ensures that emergency responders are aware of the presence of oxygen in the home in case of a fire or emergency situation.

E. Check the tops of the ears for skin breakdown:
The nasal cannula can cause pressure on the tops of the ears, potentially leading to skin breakdown, especially with prolonged use. Checking for skin breakdown and providing appropriate skin care helps prevent complications and ensures the client's comfort.

A. Verify the oxygen flow rate every other day:
While it's essential to ensure that the oxygen equipment is functioning properly and that the prescribed flow rate is appropriate for the client's needs, checking it every other day may not be necessary unless there are specific concerns or changes in the client's condition.

D. Apply petroleum ointment to nares if they become dry and irritated:
While it's common for the nasal passages to become dry with oxygen therapy, applying petroleum ointment may not be recommended without consulting the healthcare provider first, as it can interfere with oxygen delivery and increase the risk of infection.
