The nurse reviews the lab values.

Exhibits

What questions can the nurse ask the client based on the lab results? Select all that apply.

Choice A rationale: This option is not appropriate as increasing saturated fat intake would exacerbate the oily stool and flatus symptoms caused by orlistat. Orlistat is specifically designed to reduce fat absorption, and increasing fat intake would be counterproductive and may worsen the side effects.

Choice B rationale: Asking a client to describe their dietary intake history is a standard practice in nutritional assessment. It provides a baseline for understanding current eating habits and identifying areas for improvement.

Choice C rationale: Advising a client to stop taking medication should only be done by a qualified healthcare provider who has full knowledge of the client's health history and current medications.

Choice D rationale: While obtaining a stool specimen for evaluation might be relevant in some situations, it is not the priority in this case. The oily stools and flatus are most likely related to the side effects of orlistat and do not typically require stool testing for confirmation. The more immediate action would be to address the symptoms by advising the client to stop taking the medication and contact her healthcare provider for further guidance.

choice A, Drawing the peak level two hours after the IV dose is too late to capture the drug's highest serum concentration. Similarly, drawing the trough two hours before the next dose does not reflect the lowest drug level accurately.
Choice B,Drawing the peak level one hour after completion of the IV dose ensures an accurate measurement of the highest serum concentration, as vancomycin typically peaks within this time frame. Drawing the trough one hour before the next dose ensures the lowest concentration of the drug is measured, providing precise therapeutic monitoring.

Choice C is incorrect because drawing blood 30 minutes into the IV dose would not allow the full dose to circulate and reach peak levels in the bloodstream.

Choice D.Drawing the peak level immediately after the completion of the IV dose is too early, as the drug needs time to distribute in the bloodstream and reach its highest concentration. While drawing the trough 30 minutes before the next dose is appropriate, the incorrect timing of the peak makes this option unsuitable.
