When assessing a patient's bowel sounds, the nurse auscultates loud bowel sounds in each quadrant every 3 seconds. The nurse understands that these findings could indicate that the patient is experiencing which condition?

Correct Answer: A

Rationale: The correct answer is A: Diarrhea. Loud bowel sounds every 3 seconds indicate hyperactive bowel sounds, which are a common characteristic of diarrhea. Diarrhea increases peristalsis, leading to frequent loud bowel sounds. Paralytic ileus (choice B) is characterized by absent or hypoactive bowel sounds due to decreased motility. Vomiting (choice C) and constipation (choice D) are not typically associated with loud bowel sounds every 3 seconds.

Correct Answer: B

Rationale: The correct answer is B because increasing salt intake can worsen heart failure by causing fluid retention and increasing blood pressure. A is correct because shortness of breath is a common symptom of heart failure. C is incorrect because limiting fluid intake is important to prevent fluid overload in heart failure. D is correct as daily weight monitoring can help detect fluid retention early. Therefore, B is the only statement that goes against heart failure management principles.

Correct Answer: B

Rationale: The correct answer is B: smooth muscle. Smooth muscle is the most abundant type of muscle in the digestive tract due to its involuntary nature and the ability to maintain sustained contractions for digestion and movement of food. Skeletal muscle (A) is not found in the digestive tract. Cardiac muscle (C) is specific to the heart and not present in the digestive tract. Fibrous muscle (D) is not a recognized type of muscle tissue. Smooth muscle is the most suitable choice as it aligns with the functions and characteristics of muscle in the digestive system.

Correct Answer: C

Rationale: The correct answer is C: gallbladder. Bile is produced by the liver and stored in the gallbladder. When we eat, the gallbladder releases bile into the small intestine to aid in the digestion of fats. The pancreas produces digestive enzymes, not bile (A). The liver produces bile but does not store it (B). The small intestine is where bile is released, not stored (D). Therefore, the gallbladder is the correct location for bile storage.

Correct Answer: B

Rationale: Water is absorbed in the stomach through a process called osmosis, where water molecules pass through the stomach lining into the bloodstream. Vitamins are primarily absorbed in the small intestine, while carbohydrates and proteins are broken down in the stomach but absorbed in the small intestine. Water is the only substance among the choices that undergoes absorption directly in the stomach due to its small molecular size and the body's constant need for hydration.
