1. Which of the following organs of the digestive system has a primary function of absorption?

Correct answer: C

Rationale: The small intestine is the correct answer. It is the primary organ responsible for absorption in the digestive system. The stomach's primary function is to break down food through mechanical and chemical digestion. The pancreas produces digestive enzymes to aid in the breakdown of food. The gallbladder stores bile produced by the liver, which helps in the digestion of fats. However, neither the stomach, pancreas, nor gallbladder play the primary role of absorption in the digestive process, making them incorrect choices.

2. In alcoholics with anemia:

Correct answer: B

Rationale: In alcoholics with anemia, iron deficiency and folic acid deficiency can coexist due to poor dietary intake and malabsorption issues associated with chronic alcohol consumption. Pernicious anemia, primarily related to vitamin B12 deficiency, is not commonly seen in alcoholics. While alcohol can interfere with iron absorption, it is not the sole factor contributing to anemia in alcoholics. Oral vitamin replacement is not contraindicated in alcoholics with anemia; however, it may be less effective due to absorption issues related to alcohol consumption.

3. A 32-year-old male with a complaint of dizziness has an order for Morphine via IV. What should the nurse do first?

Correct answer: B

Rationale: The correct first action for the nurse to take in this situation is to retake the patient's vitals, including blood pressure. Dizziness can be a sign of hypotension, which may be a contraindication for administering Morphine. Checking the chest x-ray results (Choice A) would not be the priority in this case as addressing the dizziness is more urgent. Performing a neurological screening (Choice C) may be important but not the first step when a patient presents with dizziness and an order for Morphine. Requesting the physician to assess the patient (Choice D) should come after the initial assessment and vitals retake.

4. If your patient is acutely psychotic, which of the following independent nursing interventions would not be appropriate?

Correct answer: C

Rationale: When a patient is acutely psychotic, they may not be able to effectively participate in group therapy due to their altered mental state. Group settings can be overwhelming and may exacerbate the patient's symptoms. Choices A, B, and D are appropriate interventions. Choice A is correct as providing calmness through one-on-one interaction can be beneficial in establishing trust and reducing anxiety. Choice B is also important as recognizing and managing the nurse's feelings can prevent further escalation of the patient's symptoms. Choice D is relevant as listening and identifying causes of the patient's behavior can aid in understanding and providing appropriate care tailored to the patient's needs.

5. In a client with asthma who develops respiratory acidosis, what should the nurse expect the client's serum potassium level to be?

Correct answer: B

Rationale: In respiratory acidosis, the serum potassium level is expected to be elevated. This occurs because potassium shifts from cells into the bloodstream as a compensatory mechanism to maintain acid-base balance. Choices A, C, and D are incorrect. A normal potassium level is not expected in respiratory acidosis. A low potassium level is more commonly associated with alkalosis, not acidosis. The potassium level is indeed related to pH changes in respiratory acidosis, leading to the expected elevation.
