A nurse is preparing to administer ondansetron 4 mg IM stat.

The amount available is ondansetron for injection 2 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number.

(Use a leading zero if it applies. Do not use a trailing zero)

Choice A rationale
Determining the patency of the tubing is the first action the nurse should take. If there is no urinary output, it is important to check for any kinks or blockages in the tubing that may be preventing the flow of urine. Ensuring the patency of the tubing can help resolve the issue without the need for further intervention.
Choice B rationale
Notifying the provider is not the first action the nurse should take. The nurse should first assess the situation and determine if there is a simple solution, such as checking the patency of the tubing, before escalating the issue to the provider.
Choice C rationale
Administering a prescribed analgesic is not the first action the nurse should take. While pain management is important, it is crucial to address the lack of urinary output first to prevent complications such as bladder distention or damage.
Choice D rationale

Offering oral fluids is not the first action the nurse should take. While maintaining hydration is important, the immediate concern is to determine why there is no urinary output and address any potential blockages in the tubing.

Choice A rationale
A high-purine diet can lead to the formation of uric acid stones, which are a type of kidney stone. However, it is not the most common risk factor for urolithiasis. Urolithiasis is more commonly associated with factors such as dehydration, which leads to concentrated urine and promotes stone formation.
Choice B rationale
Female gender is not a significant risk factor for urolithiasis. In fact, men are more likely to develop kidney stones than women. The higher incidence in men is thought to be related to differences in diet, fluid intake, and urinary tract anatomy.

Choice C rationale
Dehydration is a major risk factor for urolithiasis. When the body is dehydrated, urine becomes more concentrated, which increases the likelihood of stone formation. Adequate hydration helps to dilute the urine and reduce the risk of stone formation.
Choice D rationale
Family history is a known risk factor for urolithiasis. Individuals with a family history of kidney stones are more likely to develop them due to genetic predispositions that affect factors such as urine composition and kidney function.
