A nurse is collecting data on a client who has dehydration. Which of the following findings should the nurse expect?
Urine osmolality of 200 mOsm/kg
Cloudy urine
Dark-colored urine
Urine specific gravity of 1.015
The Correct Answer is C
Choice A reason: Urine osmolality of 200 mOsm/kg is lower than expected in dehydration. Dehydration typically results in higher osmolality due to the concentration of urine.
Choice B reason: Cloudy urine can be a sign of infection or other conditions, but it is not a specific indicator of dehydration.
Choice C reason: Dark-colored urine is a common finding in dehydration as the body conserves water, leading to
more concentrated urine.
Choice D reason: A urine specific gravity of 1.015 is within the normal range. In dehydration, we would expect a higher specific gravity, indicating more concentrated urine.

Correct Answer is C
Explanation
Choice A reason: Metabolic Acidosis typically results from conditions that increase acid production or decrease acid excretion, not from vomiting.
Choice B reason: Respiratory Acidosis is caused by hypoventilation leading to an accumulation of carbon dioxide, which is not directly related to vomiting.
Choice C reason: Metabolic Alkalosis can occur due to the loss of stomach acids through prolonged vomiting, leading to an excess of bicarbonate in the body fluids.
Choice D reason: Respiratory Alkalosis is usually caused by hyperventilation, not by vomiting.
Correct Answer is C
Explanation
Choice A reason: The reservoir bag on a nonrebreather mask should not collapse with exhalation. It is designed to maintain a continuous flow of oxygen and reserve a volume of oxygen for the patient to inhale with each breath.
Choice B reason: While high-flow oxygen can dry a patient's mucous membranes, a nonrebreather mask typically has a high oxygen flow rate, and humidification can be used to prevent drying.
Choice C reason: A nonrebreather mask must fit snugly over the patient's face to ensure that the highest concentration of oxygen is delivered and that there is minimal dilution with room air.
Choice D reason: A nonrebreather mask is used to deliver high-flow oxygen, not low-flow. It is designed to provide a high concentration of oxygen, typically around 60% to 90% FiO2.
