The healthcare provider recommends to a patient that diagnostic testing be performed to assess for valvular heart disease. The nurse teaches the patient about which test that is commonly used to assess the valves?

Choice A reason: Maintaining nothing by mouth (NPO) and administering intravenous fluids is the best intervention to reduce discomfort in a patient with acute pancreatitis. NPO status helps to rest the pancreas by preventing the secretion of pancreatic enzymes that can exacerbate inflammation and pain. Intravenous fluids are essential to maintain hydration and electrolyte balance while the patient is not eating or drinking.

Choice B reason: Providing small, frequent feedings with no concentrated sweets is not appropriate for a patient with acute pancreatitis. The priority is to keep the patient NPO to rest the pancreas. Introducing any food can stimulate the pancreas and worsen the condition.

Choice C reason: Administering morphine sulfate intramuscularly every 4 hours as needed can help manage pain, but the preferred route for pain medication in acute pancreatitis is intravenous, as it provides quicker relief and avoids the discomfort of intramuscular injections. Pain management is important, but it should be part of a broader plan that includes NPO status and IV fluids.

Choice D reason: Positioning the patient in a flat, supine position is not recommended for reducing discomfort in acute pancreatitis. Patients often find relief in a semi-Fowler's position (head elevated) or by leaning forward, which can help reduce abdominal pain and pressure on the inflamed pancreas.

Choice A reason: The arterial blood gas values pH 7.25, HCO3- 19 mEq/L, and PaCO2 30 mm Hg are indicative of metabolic acidosis, which is commonly seen in chronic kidney disease (CKD). In CKD, the kidneys lose their ability to excrete hydrogen ions and retain bicarbonate, leading to a decrease in blood pH (acidosis) and a reduction in bicarbonate (HCO3-). The PaCO2 value is slightly lower as a compensatory mechanism by the lungs to help balance the pH.

Choice B reason: The values pH 7.30, HCO3- 26 mEq/L, and PaCO2 50 mm Hg suggest a state of respiratory acidosis with partial metabolic compensation. This is not typically expected in chronic kidney disease. Respiratory acidosis occurs when there is hypoventilation, leading to an accumulation of carbon dioxide (CO2) in the blood. The bicarbonate (HCO3-) level is within the normal range, indicating that it is not the primary disorder in this context.

Choice C reason: The values pH 7.50, HCO3- 20 mEq/L, and PaCO2 32 mm Hg are consistent with respiratory alkalosis, where the pH is elevated due to hyperventilation leading to a loss of CO2. This condition is not typically associated with chronic kidney disease. The bicarbonate level is slightly below normal but not enough to indicate a significant metabolic disorder.

Choice D reason: The values pH 7.55, HCO3- 30 mEq/L, and PaCO2 31 mm Hg indicate metabolic alkalosis, which is characterized by an elevated pH and increased bicarbonate. This condition can occur due to excessive loss of acids (e.g., vomiting) or an increase in bicarbonate but is not typically expected in chronic kidney disease.
