Which intervention is most important for the nurse to implement for a client who is receiving insulin lispro?

Choice A reason: This is not an appropriate instruction for the nurse to include in the client's plan of care. Replacing salt with a salt substitute is not recommended for clients taking spironolactone, as most salt substitutes contain potassium. Spironolactone is a potassium-sparing diuretic that can cause hyperkalemia, or high levels of potassium in the blood. The client should avoid salt substitutes and other sources of potassium.

Choice B reason: This is not an appropriate instruction for the nurse to include in the client's plan of care. Monitoring skin for excessive bruising is not related to the use of spironolactone, as it does not affect the blood clotting process. The client should monitor for signs of bleeding, such as nosebleeds, gum bleeding, or blood in the urine or stool, if he or she is taking other medications that can interfere with clotting, such as aspirin or warfarin.

Choice C reason: This is not an appropriate instruction for the nurse to include in the client's plan of care. Covering the skin before going outside is not necessary for clients taking spironolactone, as it does not cause photosensitivity or increased risk of sunburn. The client should protect the skin from sun exposure as part of general health promotion, but it is not specific to spironolactone therapy.

Choice D reason: This is the appropriate instruction for the nurse to include in the client's plan of care. Limiting intake of high-potassium foods is important for clients taking spironolactone, as it can prevent hyperkalemia and its complications, such as cardiac arrhythmias, muscle weakness, or paralysis. The client should avoid foods that are rich in potassium, such as bananas, oranges, tomatoes, potatoes, spinach, and dairy products. The client should also have regular blood tests to monitor the potassium levels.

Choice A reason: This is not a correct action for the nurse to include in this client's plan of care. Administering sucralfate once a day, preferably at bedtime, is not the recommended dosage or timing for this medication. Sucralfate is a mucosal protectant that forms a protective barrier over the ulcer and prevents further damage from acid and pepsin. It should be taken four times a day, one hour before meals and at bedtime, to ensure optimal coverage and healing of the ulcer.

Choice B reason: This is the correct action for the nurse to include in this client's plan of care. Giving sucralfate on an empty stomach is essential for the effectiveness of this medication. Sucralfate needs an acidic environment to activate and form a complex with the ulcer site. If the client takes sucralfate with food or beverages, the pH of the stomach may increase and reduce the ability of sucralfate to bind to the ulcer. The client should take sucralfate one hour before meals and at bedtime, and avoid antacids within 30 minutes of taking sucralfate.

Choice C reason: This is not a correct action for the nurse to include in this client's plan of care. Monitoring for electrolyte imbalance is not a specific or relevant intervention for this medication. Sucralfate does not affect the electrolyte levels in the blood, as it is not absorbed systemically and does not alter the renal function. The nurse should monitor the electrolyte levels for other reasons, such as dehydration, vomiting, or diuretic use, but not because of sucralfate therapy.

Choice D reason: This is not a correct action for the nurse to include in this client's plan of care. Assessing for secondary Candida infection is not a common or necessary intervention for this medication. Sucralfate does not increase the risk of fungal infections, as it does not suppress the immune system or alter the normal flora of the GI tract. The nurse should assess for signs of infection, such as fever, leukocytosis, or purulent drainage, for other reasons, such as perforation, abscess, or sepsis, but not because of sucralfate therapy.
