The nurse is teaching a patient with myasthenia gravis how to prevent a myasthenic crisis.
What topic is most important to include?
Wear gloves when handling frozen food items.
Avoid warm climates.
Receive an annual influenza vaccination.
Increase intake of protein.
The Correct Answer is C
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.

Correct Answer is B
Explanation
Choice A rationale
Applying vitamin E ointment is not an evidence-based treatment for facial acne. While vitamin E has antioxidant properties, its topical application has not been shown to significantly reduce acne lesions and may even exacerbate some skin conditions by occluding pores.
Choice B rationale
Washing the face twice a day with mild soap and water helps to remove excess sebum, dirt, and dead skin cells, which contribute to acne formation. This simple hygienic practice reduces bacterial colonization and prevents clogged pores without irritating the skin, which can worsen acne.
Choice C rationale
Removing whiteheads and raised areas, also known as comedone extraction, by oneself can lead to skin trauma, inflammation, infection, and scarring. This procedure should only be performed by a healthcare professional, such as a dermatologist, using sterile techniques.
Choice D rationale
Tretinoin is a retinoid that can be effective for acne, but it increases photosensitivity, making the skin more susceptible to sunburn. Therefore, applying it in the morning and exposing the face to the sun is contraindicated; it should typically be applied at night, and sun protection is crucial.
Correct Answer is A
Explanation
Choice A rationale
Bright red blood in the urine, especially in large amounts or clots, after a cystoscopy is an abnormal finding. While some pink-tinged urine is expected, significant bright red bleeding can indicate hemorrhage or bladder wall injury requiring immediate medical intervention to prevent complications.
Choice B rationale
Urinary frequency is a common and expected finding after a cystoscopy due to irritation of the bladder mucosa from the procedure. This typically resolves within a day or two as the bladder recovers from instrumentation.
Choice C rationale
Pink-tinged urine is considered a normal and expected finding after a cystoscopy. The procedure involves instrumentation of the urethra and bladder, which can cause minor trauma to the mucosal lining, leading to a small amount of blood in the urine.
Choice D rationale
Burning on urination, also known as dysuria, is a common and expected sensation after a cystoscopy due to irritation and inflammation of the urethra and bladder from the scope. This discomfort usually subsides within 24 to 48 hours.
