1. The principal cation in plasma and interstitial fluid is:

Correct answer: A

Rationale: The principal cation in plasma and interstitial fluid is sodium. Sodium plays a crucial role in maintaining fluid balance and is the primary cation in extracellular fluids like plasma and interstitial fluid. Potassium is the primary cation within cells, not in extracellular fluids, making it an incorrect choice. Calcium and magnesium are essential minerals but are not the principal cations in plasma and interstitial fluid, so they are also incorrect choices.

2. A client with chronic pancreatitis is receiving discharge teaching from a nurse. Which of the following statements should the nurse make?

Correct answer: B

Rationale: In chronic pancreatitis, it is important to increase protein intake to support healing and prevent malnutrition. Choice A is incorrect because decreasing caloric intake during abdominal pain may lead to further nutritional deficiencies. Choice C is incorrect as increasing fat intake can exacerbate symptoms due to the impaired fat digestion in chronic pancreatitis. Choice D is incorrect as alcohol should be completely avoided in chronic pancreatitis to prevent further damage to the pancreas.

3. Each is a portion of the alimentary canal, except one. Which is the exception?

The alimentary canal is involved in the digestive process and includes structures like the oral cavity (mouth), pharynx, and esophagus. Choices A, B, and D are parts of the alimentary canal, where digestion occurs, making them incorrect answers.
