When teaching an adolescent about measures to improve facial acne, the nurse should give the patient what instructions about skin care?

Choice A rationale

Lorazepam is an anxiolytic medication that can help reduce anxiety and claustrophobia, which are common concerns during an MRI. Administering 1 mg orally is a standard and safe practice to promote patient comfort and cooperation without posing a direct threat during the procedure itself.

Choice B rationale

Eating breakfast prior to an MRI scan is generally not contraindicated unless the scan requires a specific type of contrast that necessitates fasting, or if sedation is planned. For a standard MRI of the spine, food intake typically does not interfere with the imaging or pose a safety risk.

Choice C rationale

A watch and wedding band are metallic objects. MRI utilizes strong magnetic fields; ferromagnetic materials are highly attracted to these fields and can become projectiles, posing a significant risk of injury to the patient or personnel. These items can also cause image artifacts.

Choice D rationale

Positioning the patient supine is a common and appropriate position for an MRI of the spine. This position helps to immobilize the patient and allows for optimal alignment of the spinal column within the scanner, facilitating clear image acquisition without posing a safety threat.

Choice A rationale

Ciprofloxacin absorption can be significantly impaired by antacids containing aluminum, magnesium, or calcium. These antacids bind to ciprofloxacin, forming insoluble complexes that reduce the antibiotic's bioavailability, thus diminishing its effectiveness in treating the infection.

Choice B rationale

Ciprofloxacin, a fluoroquinolone antibiotic, carries a black box warning for increased risk of tendinitis and tendon rupture. Patients should be instructed to monitor for tendon pain, especially in the Achilles tendon, and report it immediately to prevent severe and permanent injury.

Choice C rationale

Limiting fluid intake is contraindicated when taking ciprofloxacin for a UTI. Adequate hydration is crucial to help flush bacteria from the urinary tract and prevent crystalluria, a potential side effect where drug crystals form in the urine, which can lead to kidney damage.

Choice D rationale

Ciprofloxacin does not typically cause urine to turn dark orange. This side effect is more commonly associated with other medications, such as rifampin or phenazopyridine (a urinary analgesic), and is not an expected or normal finding when taking ciprofloxacin.
