A nurse is assisting with the care of a school-age child who has respiratory failure due to pneumonia. Which of the following positions should the nurse encourage to allow maximal lung expansion?

Choice A reason: Obtaining a prescription to administer insulin is an important action for the nurse to take, as insulin helps to lower the blood glucose level and reverse the metabolic acidosis caused by diabetic ketoacidosis. However, it is not the first action the nurse should take, as the client's hypoxia is a more urgent problem that requires immediate intervention.

Choice B reason: Obtaining a prescription for supplemental oxygen is the first action the nurse should take, as hypoxia is a life-threatening condition that can lead to tissue damage, organ failure, and death. The nurse should provide oxygen therapy to improve the client's oxygen saturation and prevent further complications.

Choice C reason: Obtaining a prescription to check the client's glucose level is a necessary action for the nurse to take, as glucose monitoring helps to evaluate the client's response to insulin therapy and guide further interventions. However, it is not the first action the nurse should take, as the client's hypoxia is a more urgent problem that requires immediate intervention.

Choice D reason: Obtaining a prescription to administer intravenous fluids is a beneficial action for the nurse to take, as fluid replacement helps to correct the dehydration, electrolyte imbalance, and hypotension caused by diabetic ketoacidosis. However, it is not the first action the nurse should take, as the client's hypoxia is a more urgent problem that requires immediate intervention.

Choice A reason: Spinach is a good source of potassium, but not the best. According to the USDA, one cup of cooked spinach contains 839 mg of potassium, which is about 18% of the recommended daily intake (RDI) for adults².

Choice B reason: Baked potato is the best source of potassium among the choices. According to the USDA, one medium baked potato with skin contains 941 mg of potassium, which is about 20% of the RDI for adults². Potassium is an essential mineral that helps regulate fluid balance, nerve and muscle function, and blood pressure.

Choice C reason: Banana is a popular source of potassium, but not the best. According to the USDA, one medium banana contains 422 mg of potassium, which is about 9% of the RDI for adults².

Choice D reason: Cheese is a poor source of potassium. According to the USDA, one ounce of cheddar cheese contains only 28 mg of potassium, which is less than 1% of the RDI for adults². Cheese is high in sodium, which can counteract the benefits of potassium and increase the risk of hypertension.
