The nurse receives a health care provider's prescription to change a patient's IV from D5. half-normal saline with 40 mEq KCl/L to DSNS with 20 mEq KCl/L. Which set of serum laboratory values supports the rationale for this IV prescription change?

Choice A rationale:

While magnesium is indeed the most abundant intracellular cation in the body, this fact alone does not explain why the nurse would assess the patient's magnesium level.

Choice B rationale:

Magnesium imbalance can cause issues in the extracellular fluid compartment, but this choice does not explain why the nurse would specifically assess the patient's magnesium level.

Choice D rationale:

While hypotension can be a symptom of severe magnesium deficiency, this choice does not provide a rationale for assessing the patient's magnesium level. In this case, choice C is correct because magnesium plays a crucial role in neuromuscular excitability and contractility. Abnormal magnesium levels can lead to neuromuscular symptoms such as muscle weakness, tremors, and spasms. Additionally, magnesium is involved in cardiac muscle function, and low magnesium levels can lead to arrhythmias and other cardiac issues. Therefore, assessing the patient's magnesium level is essential in understanding their neuromuscular and cardiac health.

Choice A rationale:

Restricting all visitors might be beneficial in preventing infections, but it is not the most important strategy for a patient with neutropenia. The main concern is the risk of infections due to the compromised immune system.

Choice B rationale:

Placing the patient in a private room is crucial for a neutropenic patient. Neutropenia, characterized by a low absolute neutrophil count (ANC), significantly compromises the patient's immune system, making them highly susceptible to infections. Isolating the patient helps minimize the risk of exposure to pathogens, reducing the likelihood of infections.

Choice C rationale:

Using an electric shaver instead of a razor is advisable to prevent cuts and minimize the risk of skin infections. While this is a good practice, it is not the most important strategy compared to isolating the patient and using personal protective equipment (PPE) during direct patient care.

Choice D rationale:

Wearing a gown and gloves when in direct contact with the patient is essential to prevent the spread of infections. This is a necessary measure, but isolating the patient in a private room takes precedence as it minimizes the risk of exposure to pathogens, providing a safer environment for the neutropenic patient.
