A client with acute renal injury (AKI) weighs 110.3 pounds (50 kg) and has a potassium level of 6.7 mEq/L (6.7 mmol/L) is admitted to the hospital. Which prescribed medication should the nurse administer first?

Reference Range:
Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)]

Choice A reason: This is incorrect because reviewing the need for pneumococcal vaccine is not the most important intervention for the nurse to implement. Pneumococcal vaccine is recommended for people who are at high risk of pneumococcal infections, such as those with chronic diseases or immunosuppression. However, it is not a priority action for a client with neutropenia, which is a low number of neutrophils that increases the risk of bacterial and fungal infections.

Choice B reason: This is incorrect because implementing bleeding precautions is not the most important intervention for the nurse to implement. Bleeding precautions are indicated for clients who have thrombocytopenia, which is a low number of platelets that impairs blood clotting. However, this is not the case for a client with neutropenia, which affects the white blood cells that fight infections.

Choice C reason: This is incorrect because assessing vital signs every 4 hours is not the most important intervention for the nurse to implement. Vital signs are important indicators of the client's health status and may reveal signs of infection, such as fever, tachycardia, or hypotension. However, this is not a sufficient measure to prevent or treat infections in a client with neutropenia, who needs more aggressive and proactive interventions.

Choice D reason: This is correct because placing the client in protective isolation is the most important intervention for the nurse to implement. Protective isolation, also known as reverse isolation or neutropenic precautions, is a set of measures that aim to protect the client from exposure to pathogens that may cause infections. These include wearing gloves, masks, gowns, and eye protection; using sterile equipment and techniques; avoiding contact with people who are sick or have infections; and restricting visitors and fresh flowers or fruits.

Choice A reason: Canned vegetables with additional table salt are not a good choice for someone with cholecystitis, because they are high in sodium, which can increase fluid retention and inflammation. However, this choice is not eliminated by the client, so it does not indicate successful teaching.

Choice B reason: Pasta with herbal butter and no meat sauce is a good choice for someone with cholecystitis, because it is low in fat and protein, which can trigger gallbladder contractions and pain. This choice is not eliminated by the client, so it does not indicate successful teaching.

Choice C reason: Citrus fruit and melon with a salt substitute are also good choices for someone with cholecystitis, because they are high in vitamin C and water, which can help dissolve gallstones and prevent infection. This choice is not eliminated by the client, so it does not indicate successful teaching.

Choice D reason: Whole milk and daily servings of ice cream are bad choices for someone with cholecystitis, because they are high in fat and cholesterol, which can worsen gallbladder inflammation and increase the risk of gallstone formation. This choice is eliminated by the client, so it indicates successful teaching.
