Correct Answer: C

Rationale: The correct answer is C. There should be 2 cm of water in the water seal chamber of the chest tube system. A level of 1 cm may indicate a leak or compromised functionality that requires intervention. Choices A, B, and D are not findings that necessarily require immediate intervention. Tidaling with spontaneous respirations is an expected finding, the drainage collection chamber being 1/3 full is within normal limits, and a suction chamber pressure of -20 cm H2O indicates appropriate suction for chest drainage.

Correct Answer: C

Rationale: Offering to go for a walk with the client helps redirect their energy in a non-confrontational way, avoiding escalation of aggressive behavior while promoting de-escalation.

Correct Answer: B

Rationale: The correct answer is B: 'Drink peppermint tea.' Peppermint tea can help relax the smooth muscles of the gastrointestinal tract, reducing symptoms of IBS, such as bloating and abdominal discomfort. Choices A, C, and D are incorrect. Decreasing fiber intake is not recommended for IBS management as fiber can help regulate bowel movements. Increasing foods high in fat can exacerbate symptoms of IBS, as high-fat foods can be harder to digest. Avoiding foods with gluten is more relevant for individuals with gluten sensitivity or celiac disease, not specifically for IBS management.

Correct Answer: C

Rationale: The correct answer is C: Flat affect. Negative symptoms of schizophrenia involve deficits in normal emotional responses or other thought processes. These symptoms include a flat affect (reduced emotional expression), social withdrawal, and avolition (lack of motivation). Hallucinations and delusions are characteristic of positive symptoms, which involve the presence of abnormal behaviors or experiences. Paranoia is more associated with delusions rather than negative symptoms.

Correct Answer: C

Rationale: In acute pancreatitis, the nurse should expect elevated blood glucose levels. This is due to impaired insulin production by the inflamed pancreas. While serum amylase and lipase levels are typically elevated in acute pancreatitis, blood glucose levels are also affected due to the pancreatic dysfunction. Therefore, choices A and B are incorrect. Elevated calcium levels are not typically associated with acute pancreatitis, making choice D incorrect.
