What is the most effective nursing intervention to include in the patient's plan of care to prevent urinary tract infections?

Choice A rationale

Wearing gloves when handling frozen food items is not related to preventing a myasthenic crisis. A myasthenic crisis is characterized by severe muscle weakness, including respiratory muscles, and is often triggered by infection or medication changes, not temperature exposure to hands.

Choice B rationale

Avoiding warm climates is not a primary preventative measure for myasthenic crisis. While extreme temperatures can sometimes exacerbate symptoms in some individuals with myasthenia gravis, it is not a direct trigger for a crisis. Infections are a far more common precipitating factor.

Choice C rationale

Receiving an annual influenza vaccination is crucial for preventing infections, which are a common trigger for myasthenic crisis. Infections, particularly respiratory infections, can significantly worsen muscle weakness and precipitate life-threatening respiratory compromise in patients with myasthenia gravis.

Choice D rationale

Increasing intake of protein does not directly prevent a myasthenic crisis. While adequate nutrition is important for overall health, there is no specific evidence that increased protein intake prevents the acute exacerbation of muscle weakness characteristic of a myasthenic crisis.

Choice A rationale

Collecting the second voided specimen of the day is not the standard procedure for a clean-catch urine sample. A clean-catch specimen aims to collect urine mid-stream after initial flushing, regardless of the time of day, to minimize contamination from the urethra and external genitalia.

Choice B rationale

When obtaining a clean-catch urine specimen, the patient should void a small initial amount into the toilet. This initial stream helps to flush out microorganisms from the distal urethra and periurethral area, reducing contamination of the collected specimen and ensuring a more accurate representation of bladder urine.

Choice C rationale

Restricting fluids before specimen collection is generally contraindicated for a clean-catch urine. Adequate hydration ensures sufficient urine volume for collection and can help to dilute contaminants, making it easier to obtain a clean mid-stream sample. Fluid restriction may lead to a concentrated, insufficient sample.

Choice D rationale

Placing the specimen in a clean urinalysis container is insufficient; the container must be sterile. A non-sterile container can introduce external contaminants into the urine sample, leading to inaccurate laboratory results, potentially causing misdiagnosis or inappropriate treatment for a urinary tract infection.
