Which of the following results should the nurse expect? Negative urine ketones BUN 32 mg/dL pH 7.43 HCO3- 23 mEq/L - correct answers.BUN 32 mg/dL DKA results in osmotic diuresis and subsequent dehydration. The nurse should expect a client who has DKA to have elevated BUN, creatinine, and specific gravity levels resulting from the excess glucose present in the urine. A client who has DKA experiences ketosis, which results in ketones in the urine and blood. The nurse should expect a client who has DKA to have a pH level less than 7.35 due to the increased production of ketones, which results in metabolic acidosis. The client might exhibit Kussmaul respirations, which are deep and rapid respirations that compensate for the decreased pH. Sodium bicarbonate is administered for severe acidosis when the client's pH level is less than 7. The nurse should expect a client who has DKA to have an HCO3- less than 15 mEq/L. This decreased value is due to an increased production of ketones, resulting in metabolic acidosis. A nurse and an assistive personnel (AP) are caring for a client who has bacterial meningitis.

"While taking this medication, I will experience flushing of my skin." - correct answers."I should take this medication with a meal." The client should take metformin with or immediately following meals to improve absorption and to minimize gastrointestinal distress. Metformin decreases the amount of glucose produced in the liver and increases tissue sensitivity to insulin. Typically, clients lose weight when beginning to take metformin due to nausea and vomiting. Flushing of the skin is not an adverse effect of metformin.

Report of a night cough Report of tinnitus Report of excessive tearing Report of increased salivation - correct answers.Report of a night cough The nurse should recognize that a night cough is an early indication of heart failure and report this adverse reaction to the provider. Propranolol is a nonselective beta-adrenergic antagonist that has sensory effects, including dry eyes and vision changes. However, tinnitus is not an adverse effect of propranolol. Propranolol is a nonselective beta-adrenergic antagonist that can affect the heart, the lungs, and the eyes. Ophthalmic adverse effects include blurred vision and dry eyes. Propranolol is a nonselective beta-adrenergic antagonist that has several gastrointestinal effects, such as dry mouth, abdominal cramping, constipation, and diarrhea.
