A nurse is reviewing the medical record of a client who has a new prescription for verapamil. Which of the following findings in the client's medical record should the nurse identify as a contraindication for the administration of verapamil?

When assessing a client receiving ciprofloxacin, the nurse should prioritize reporting tendon pain when walking to the provider. Ciprofloxacin is a fluoroquinolone antibiotic that can rarely cause tendonitis or tendon rupture, particularly in the Achilles tendon. Tendon pain, especially when associated with difficulty walking, can be indicative of a serious adverse effect and requires immediate attention and evaluation by the provider.

Nausea and vomiting (A) are common side effects of ciprofloxacin but are typically not considered urgent or life-threatening. They can often be managed with supportive care measures and may not require immediate intervention.

Daytime drowsiness (B) is not typically associated with ciprofloxacin and may be unrelated to the medication. It should be assessed and reported if it persists or is severe, but it is not a priority finding specifically related to ciprofloxacin administration.

Photosensitivity (D) is a known side effect of ciprofloxacin, but it is not typically considered a priority finding unless it is severe or causing significant discomfort. Adequate sun protection measures can help manage photosensitivity.

A nurse who is caring for a preschooler should question a prescription for tetracycline. Tetracycline is contraindicated in children under 8 years of age due to its potential to cause permanent discoloration and damage to developing teeth and bones. This adverse effect is known as tooth staining or dental hypoplasia.

Let's go through the other options:

A. Azithromycin: Azithromycin is an appropriate antibiotic for use in preschool-age children and is commonly prescribed for various bacterial infections. It does not pose the same risk of tooth staining as tetracycline, making it a safe option for this age group.

C. Cefuroxime: Cefuroxime is another antibiotic that is safe for use in preschoolers. It belongs to the cephalosporin class of antibiotics and is commonly prescribed for respiratory tract infections, skin infections, and other bacterial infections.

D. Gentamicin: While gentamicin is an effective antibiotic, its use in preschool-age children should be carefully monitored. Gentamicin can have potential ototoxic and nephrotoxic effects (damage to the inner ear and kidneys, respectively). However, its use is not strictly contraindicated in this age group, and it can be prescribed when necessary with appropriate monitoring.
