When teaching an adolescent about measures to improve facial acne, the nurse should give the patient what instructions about skin care?
Apply vitamin E ointment twice daily to the affected skin.
Wash the face twice a day with mild soap and water.
Remove whiteheads and raised areas after washing their face with antibacterial soap.
Apply tretinoin daily in the morning and expose the face to the sun.
The Correct Answer is B
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.
Correct Answer is D
Explanation
Choice A rationale
Cerebral angiography involves injecting contrast into cerebral arteries to visualize blood vessels, primarily used for conditions like aneurysms or arteriovenous malformations. While some vascular abnormalities can cause seizures, it is not the primary diagnostic test for initial seizure disorder evaluation.
Choice B rationale
Electromyography (EMG) measures the electrical activity of muscles in response to nerve stimulation. It is used to diagnose neuromuscular disorders, such as myasthenia gravis or peripheral neuropathies, and is not the primary diagnostic tool for a seizure disorder.
Choice C rationale
A lumbar puncture involves collecting cerebrospinal fluid (CSF) for analysis, primarily used to diagnose infections, inflammatory conditions, or certain neurological disorders. While it might be performed in some seizure contexts to rule out infection, it is not the initial or primary test for seizure disorder diagnosis.
Choice D rationale
Electroencephalography (EEG) records the electrical activity of the brain. It is the gold standard for diagnosing seizure disorders because it can detect abnormal neuronal discharges characteristic of seizures and help classify seizure types, providing crucial information for treatment planning.
