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. Among people who are ill, significant weight loss may be masked by?

A. dehydration
B. a large tumor
C. drug therapy
D. fluid retention

Correct answer: D

Rationale: Fluid retention can mask weight loss in ill individuals as the retained fluid adds to body weight, making it difficult to detect true fat or muscle loss. Dehydration (Choice A) would actually lead to weight loss rather than masking it. While a large tumor (Choice B) could contribute to weight loss, it would not mask the weight loss itself. Drug therapy (Choice C) may cause side effects, including weight changes, but it is unlikely to mask significant weight loss in the same way that fluid retention does.

3. For a client with metabolic syndrome, which dietary change is most beneficial?

A. Increase intake of refined sugars
B. Decrease intake of trans fats
C. Increase intake of red meat
D. Decrease intake of whole grains

Correct answer: B

Rationale: Decreasing trans fats helps manage metabolic syndrome by improving lipid profiles.

4. Characteristics of type two diabetes include all of the following except:

A. insulin resistance
B. blood glucose levels that rise too high
C. blood insulin levels that rise too high
D. rapid destruction of the pancreas

Correct answer: D

Rationale: Type 2 diabetes is characterized by insulin resistance, high blood glucose levels, and high blood insulin levels. Rapid destruction of the pancreas is not a feature of this condition. The destruction of pancreatic beta cells is more commonly associated with type 1 diabetes, not type 2 diabetes. Therefore, option D is the correct answer. Options A, B, and C are all characteristic features of type 2 diabetes, making them incorrect choices.

5. You are taking care of critically ill client and the doctor in charge calls to order a DNR (do not resuscitate) for the client. Which of the following is the appropriate action when getting DNR order over the phone?

A. Have the registered nurse, family spokesperson, nurse supervisor and doctor sign
B. Have 2 nurse validate the phone order, both nurses sign the order and the doctor should sign his order within 24
C. Have the registered nurse, family and doctor sign the order
D. Have 1 nurse take the order and sign it and have the doctor sign it within 24 hours

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
