The nurse receives a prescription for ciprofloxacin 400 mg intravenously (IV) every 12 hours to be infused over an hour. The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (D5W) 200 mL. The nurse should program the infusion pump to deliver how many mL/hr? (Enter numerical value only.)

Choice A reason: A cool, humidified air is not relevant for this client, as it does not affect the eyes or vision. A cool, humidified air may be beneficial for clients with respiratory conditions, such as asthma or bronchitis.

Choice B reason: A quiet, restful environment is not specific for this client, as it does not address the effects of mydriatic medication on the eyes or vision. A quiet, restful environment may be helpful for clients with stress, anxiety, or insomnia.

Choice C reason: A dimly lit room is the best environment for this client, as it reduces the glare and discomfort caused by mydriatic medication. Mydriatic medication is a type of eye drop that dilates the pupils and prevents them from constricting in response to light. This can improve the examination of the retina and optic nerve, but it also makes the eyes more sensitive to light and reduces the ability to focus on near objects.

Choice D reason: A warm room temperature is not necessary for this client, as it does not affect the eyes or vision. A warm room temperature may be comfortable for clients with cold intolerance, such as hypothyroidism or Raynaud's phenomenon.

Choice D reason: Probenecid is a uricosuric drug that increases the excretion of uric acid in the urine by inhibiting its reabsorption in the kidneys. Uric acid is a waste product that results from the breakdown of purines, which are found in certain foods and drinks, such as meat, seafood, beer, and wine. Probenecid is used to treat gout, a type of arthritis that occurs when uric acid crystals accumulate in the joints and cause inflammation, pain, swelling, and stiffness. By lowering uric acid levels in the blood, probenecid can prevent gout attacks and reduce joint damage.

Choice A reason: Increasing the strength of the urine stream is not a purpose of probenecid, but rather a possible effect of some medications that relax or dilate the urinary tract muscles, such as alpha-blockers or anticholinergics. These medications can help to improve urinary flow and reduce symptoms of benign prostatic hyperplasia (BPH), or enlarged prostate gland, which can cause difficulty urinating or weak urine stream.

Choice B reason: Preventing the formation of kidney stones is not a purpose of probenecid, but rather a potential benefit of some medications that lower calcium or oxalate levels in the urine, such as thiazide diuretics or potassium citrate. These medications can help to prevent calcium oxalate stones, which are one of the most common types of kidney stones. Kidney stones are hard deposits of minerals and salts that form in the kidneys and can cause severe pain, nausea, vomiting, and blood in the urine.

Choice C reason: Decreasing pain and burning during urination is not a purpose of probenecid, but rather a desired outcome of some medications that treat urinary tract infections (UTIs), such as antibiotics or phenazopyridine. These medications can help to eliminate the bacteria that cause UTIs and relieve the discomfort and inflammation that they cause. UTIs are infections that affect the bladder, urethra, or kidneys and can cause frequent or urgent urination, pain or burning during urination, cloudy or foul-smelling urine, and fever.
