1. Which organ absorbs water and vitamin K and may be affected by ulcerative colitis?

A. Stomach
B. Pancreas
C. Large intestine
D. Small intestine

Correct answer: C

Rationale: The large intestine is the organ that is primarily responsible for the absorption of water and vitamin K in the human body. A disease like ulcerative colitis can disrupt these functions by causing inflammation and ulcers in the lining of the large intestine, leading to digestive issues. The stomach (Choice A) primarily functions to break down and digest food, not to absorb water and vitamins. The pancreas (Choice B) secretes enzymes to aid in digestion and hormones to regulate blood sugar, but does not absorb water and vitamins. The small intestine (Choice D) is primarily responsible for absorbing nutrients from digested food, but not specifically water and vitamin K. Therefore, these other choices are incorrect.

2. What type of diet would most likely benefit a patient with cystic fibrosis?

A. Low sodium
B. Low fat
C. Clear liquid
D. High calorie, high protein

Correct answer: D

Rationale: Patients with cystic fibrosis often have malabsorption issues, leading to increased energy needs. A high-calorie, high-protein diet is recommended to help meet these needs, support growth, and maintain overall health. Choices A, B, and C do not address the specific dietary requirements associated with cystic fibrosis, making them less beneficial for these patients.

A. is there any fever?

A. Most frequently in nurses with needlesticks
B. Only if there is a large viral load in the blood

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
