A young child is brought to the emergency department with severe dehydration secondary to acute diarrhea and vomiting. Therapeutic management of this child will begin with which intervention?
Clear liquids, 1 to 2 ounces at a time.
Administration of antidiarrheal medication.
Oral rehydration solution (ORS).
Intravenous fluids.
The Correct Answer is C
The correct answer is choice C: Oral rehydration solution (ORS).
Choice A rationale:
Clear liquids, 1 to 2 ounces at a time, might not be sufficient to adequately rehydrate a child with severe dehydration. Clear liquids lack the necessary electrolytes and glucose content to effectively combat dehydration and replace lost fluids.
Choice B rationale:
Administration of antidiarrheal medication is not the initial step in managing severe dehydration caused by acute diarrhea and vomiting. Antidiarrheal medications can slow down the gastrointestinal motility, which may exacerbate the problem by delaying the elimination of the causative agent and prolonging the dehydration.
Choice C rationale:
Oral rehydration solution (ORS) is the recommended initial intervention for managing severe dehydration caused by acute diarrhea and vomiting. ORS contains the appropriate balance of electrolytes (sodium, potassium, chloride) and glucose to replace lost fluids and electrolytes, thereby helping to rehydrate the child effectively. It is absorbed even when digestion is impaired due to the illness.
Choice D rationale:
Intravenous fluids might be necessary if the child's condition is very severe and oral intake cannot be maintained. However, it's not the first-line intervention. Oral rehydration is preferred whenever feasible because it is less invasive and can be administered even in mild to moderate dehydration cases.

Correct Answer is ["A","D","E"]
Explanation
The correct answers are choices A, D, and E. Unequal waist angles, an uneven hemline, and asymmetry of the shoulders.
Choice A rationale:
Unequal waist angles can be an indication of scoliosis, a condition characterized by abnormal lateral curvature of the spine. When the spine curves, it can cause one side of the waist to appear higher than the other, leading to unequal waist angles. This is a key physical finding in scoliosis assessment.
Choice B rationale:
Complaints of a sore back are a non-specific symptom and may not directly indicate scoliosis. While scoliosis can sometimes cause discomfort or pain, it's not the primary assessment finding that the nurse should expect to observe.
Choice C rationale:
Inability to bend at the waist is not a typical assessment finding of scoliosis. Scoliosis primarily involves the lateral curvature of the spine, which can lead to visible asymmetry and postural changes rather than restrictions in bending.
Choice D rationale:
An uneven hemline can be a sign of scoliosis. When the spine curves, it can cause the hips and shoulders to become misaligned, leading to changes in the alignment of clothing and accessories, such as an uneven hemline.
Choice E rationale:
Asymmetry of the shoulders is a common manifestation of scoliosis. One shoulder may appear higher than the other due to the lateral curvature of the spine. This asymmetry is often more noticeable when the child is viewed from behind.
Correct Answer is A
Explanation
Choice A rationale:
Calcium carbonate is often given with meals to individuals with chronic renal disease, especially those on dialysis. One of the primary purposes is to bind dietary phosphorus in the gastrointestinal tract. In chronic renal disease, the kidneys are less effective at filtering out excess phosphorus from the blood, leading to elevated phosphorus levels (hyperphosphatemia). Elevated phosphorus levels can contribute to bone and mineral disorders in these patients. Calcium carbonate forms insoluble calcium phosphate complexes with dietary phosphorus, preventing its absorption and facilitating its elimination from the body through the feces.
Choice B rationale:
While calcium carbonate can interact with fat-soluble vitamins like vitamin D, the primary reason for administering it to individuals with chronic renal disease is to manage phosphorus levels. Calcium carbonate can bind phosphorus and prevent its absorption, which is particularly important for patients with compromised kidney function.
Choice C rationale:
Stimulating appetite is not a primary purpose of administering calcium carbonate to children with chronic renal disease. The main focus is on managing phosphorus levels and preventing complications associated with hyperphosphatemia.
Choice D rationale:
Preventing vomiting is not a primary purpose of giving calcium carbonate to children with chronic renal disease. Calcium carbonate is typically used to manage phosphorus levels and complications related to hyperphosphatemia in this population.
