Correct Answer: D

Rationale: The correct answer is D, oatmeal. Oatmeal contains insoluble fiber, which can exacerbate the symptoms of irritable bowel syndrome. Choices A, B, and C are not typically problematic for individuals with IBS. Lean cuts of pork, low-fat yogurt, and white bread are generally well-tolerated and may even be recommended as part of a balanced diet for individuals with IBS.

Correct Answer: B

Rationale: The correct answer is to use a 7th-grade reading level. This technique ensures that the information provided is accessible and easily understandable for most clients. Using simple language helps to avoid confusion and ensures that the message is conveyed clearly. Emphasizing important information using bold lettering (Choice A) can be helpful but may not improve overall accessibility. Avoiding cartoons in the material (Choice C) is not directly related to making information accessible. Using words with three or four syllables (Choice D) can complicate the material and hinder understanding, making it less accessible.

Correct Answer: C

Rationale: The correct answer is C: "Avoid drinking more than 1 liter of fluid per day." Clients with heart failure are typically advised to limit their fluid intake to around 1 liter per day to prevent fluid overload, which can worsen their condition. Choices A, B, and D are incorrect because they suggest fluid intakes that are higher than the recommended limit, which could lead to fluid retention and exacerbate heart failure symptoms.

Correct Answer: A

Rationale: The correct answer is A: 'There is no fluctuation in the water seal chamber.' In a client with a pneumothorax being treated with a chest tube, the absence of fluctuation in the water seal chamber indicates that the lung has re-expanded. This finding suggests that there is no air leak from the lung into the pleural space. Choices B and C are incorrect because continuous bubbling in the suction control chamber or tidaling in the water seal chamber would suggest ongoing air leakage, indicating that the lung has not fully re-expanded. Choice D is also incorrect as the position of the drainage system does not directly indicate lung re-expansion.

Correct Answer: C

Rationale: Elevated random serum glucose levels of 190 mg/dL indicate hyperglycemia and poor blood sugar control, requiring a revised plan of care. HbA1c levels above 7% also indicate long-term poor control of blood sugar. Serum sodium of 144 mEq/L and creatinine of 1.2 mg/dL are within normal ranges and do not directly indicate a need for a plan of care revision.
