A nurse in a clinic is collecting data from a client who has cystitis. Which of the following findings should the nurse expect?

Choice A rationale
Regular insulin is correct because it is a short-acting insulin that can be used to treat diabetic ketoacidosis (DKA). The client’s symptoms of confusion, flushed appearance, and acetone odor on the breath suggest DKA, which requires prompt treatment with insulin to lower blood glucose levels and correct metabolic acidosis. Regular insulin has a rapid onset of action and can be administered intravenously to achieve quick results.
Choice B rationale
NPH insulin is incorrect because it is an intermediate-acting insulin that is not suitable for the immediate treatment of DKA. NPH insulin has a slower onset of action and is typically used for

basal insulin coverage rather than for acute management of hyperglycemia. In cases of DKA, rapid-acting or short-acting insulin is preferred to achieve quick glucose control.
Choice C rationale
Glargine insulin is incorrect because it is a long-acting insulin that provides basal insulin coverage over 24 hours. It is not suitable for the immediate treatment of DKA, as it does not have a rapid onset of action. Glargine insulin is typically used for maintaining stable blood glucose levels over a prolonged period rather than for acute management of hyperglycemia.
Choice D rationale
Detemir insulin is incorrect because it is a long-acting insulin similar to glargine. It provides basal insulin coverage and is not suitable for the immediate treatment of DKA. Detemir insulin has a slower onset of action and is used for maintaining stable blood glucose levels rather than for rapid correction of hyperglycemia in acute situations.

Choice A rationale
Drinking 16 oz of cranberry juice each day is correct. Cranberry juice has been shown to help prevent UTIs by inhibiting the adhesion of bacteria to the urinary tract lining. This can reduce the risk of infection, especially in individuals prone to recurrent UTIs.
Choice B rationale

Using an over-the-counter douche product after intercourse is incorrect. Douching can disrupt the natural balance of bacteria in the vagina, increasing the risk of infection. It is generally not recommended as a preventive measure for UTIs.
Choice C rationale
Waiting to void until the bladder feels full is incorrect. Delaying urination can lead to the accumulation of bacteria in the bladder, increasing the risk of infection. It is important to urinate regularly and not hold urine for extended periods.
Choice D rationale
Wearing underwear made from nylon is incorrect. Nylon underwear can trap moisture and create a warm, humid environment that promotes bacterial growth. It is better to wear breathable, cotton underwear to reduce the risk of UTIs.
