Correct Answer: C

Rationale: The correct action the nurse should take when caring for a client with a chest tube is to keep the drainage system below the level of the client's chest. This positioning helps prevent fluid from flowing back into the pleural space, ensuring proper drainage and effective functioning of the chest tube. Clamping the chest tube intermittently or stripping it frequently can lead to complications and should be avoided. Emptying the drainage collection chamber at specific intervals may vary based on institutional protocols, but it should be done when it is no more than two-thirds full to prevent backflow and maintain accurate monitoring of drainage output.

Correct Answer: B

Rationale: The correct answer is B: Amylase. Amylase is typically elevated in clients with acute pancreatitis due to inflammation of the pancreas. Elevated serum creatinine levels are more indicative of kidney dysfunction rather than pancreatitis. Hemoglobin levels are not directly related to pancreatitis. While blood glucose levels can be affected by pancreatitis, they are not typically the primary laboratory result expected to be elevated in this condition.

Correct Answer: A

Rationale: Corrected Rationale: Weak femoral pulses are an expected finding in an infant with coarctation of the aorta. The narrowing of the aorta leads to decreased blood flow to the lower extremities, resulting in weak or absent femoral pulses. Frequent nosebleeds (Choice B) are not typically associated with coarctation of the aorta. Upper extremity hypotension (Choice C) is not a common finding in coarctation of the aorta; instead, blood pressure is usually elevated in the upper extremities. Increased intracranial pressure (Choice D) is not directly related to coarctation of the aorta.

Correct Answer: B

Rationale: Irritability is a common early manifestation of hypoglycemia. When blood glucose levels drop, the brain perceives this as a stressor, leading to irritability. Abdominal cramps (choice A) are not typically associated with hypoglycemia but can occur with other gastrointestinal issues. Increased thirst (choice C) is more indicative of hyperglycemia rather than hypoglycemia. Blurred vision (choice D) is a symptom more commonly associated with hyperglycemia rather than hypoglycemia.

Correct Answer: C

Rationale: The correct answer is C: White bread. White bread is low in potassium, making it a suitable choice for clients with chronic kidney disease to prevent hyperkalemia. Canned soup (choice A), bananas (choice B), and processed meats (choice D) are high in potassium and should be limited or avoided by individuals with chronic kidney disease to manage their condition effectively.
