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

• A. stomach
• B. pancreas
• C. small intestine
• D. gallbladder

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. A month after receiving a blood transfusion, an immunocompromised client develops fever, liver abnormalities, a rash, and diarrhea. The nurse should suspect this client has:

• A. no relation to the blood transfusion.
• B. graft-versus-host disease (GVHD).
• C. myelosuppression.
• D. an allergic reaction to a recent medication.

Correct answer: B

Rationale: In this scenario, the symptoms of fever, liver abnormalities, rash, and diarrhea in an immunocompromised client a month after a blood transfusion are indicative of graft-versus-host disease (GVHD). GVHD occurs when white blood cells in donor blood attack the tissues of an immunocompromised recipient. This process can manifest within a month of the transfusion. While choices 1 and 4 are plausible, it is crucial for the nurse to consider the possibility of GVHD in immunocompromised transfusion recipients due to the significant risk. Myelosuppression, choice C, typically presents with decreased blood cell counts and is not consistent with the symptoms described. An allergic reaction to medication, choice D, would present with different manifestations such as itching, hives, or anaphylaxis, which are not described in the scenario.

3. What happens if folic acid is administered to treat anemia without determining its underlying cause?

• A. Erythropoiesis is inhibited
• B. Excessive levels of folic acid might accumulate, causing toxicity
• C. The symptoms of pernicious anemia might be masked, delaying treatment
• D. Intrinsic factor is destroyed

Correct answer: C

Rationale: When folic acid is given without determining the underlying cause of anemia, the symptoms of pernicious anemia may be masked, potentially delaying the correct treatment. Folic acid alone does not protect against the central nervous system changes seen in pernicious anemia, which are related to Vitamin B12 deficiency. Folic acid and Vitamin B12 are both crucial for cell growth and division. Administering folic acid without knowing the specific type of anemia could lead to a delay in addressing the root cause. Option A is incorrect because folic acid is essential for erythropoiesis, the production of red blood cells. Option B is incorrect as excessive folic acid can cause toxicity, but it is not the primary concern in this context. Option D is incorrect because folic acid treatment for anemia does not directly impact intrinsic factor, which is related to Vitamin B12 absorption.

4. On morning rounds, the nurse finds a somnolent client with a Blood glucose of 89 mg/dL. A sulfonurea and a proton pump inhibitor are scheduled to be administered. What is the nurse's best action?

• A. Give the proton pump inhibitor and hold the sulfonurea until the client eats
• B. Hold medications and notify the physician
• C. Arouse the client and give some orange juice with sugar packets added
• D. Give the medications as ordered and re-check blood sugar in one hour

Correct answer: A

Rationale: The correct action is to give the proton pump inhibitor and hold the sulfonurea until the client eats. Sulfonureas should be held for blood glucose levels below 100 mg/dL until the client has food to prevent hypoglycemia. Giving the proton pump inhibitor is appropriate and does not need to be delayed. Option B is incorrect because holding both medications without taking appropriate action may lead to further complications. Option C is not the best choice as it does not address the need to hold the sulfonurea until the client eats. Option D is incorrect because administering the medications without ensuring the client eats may lead to hypoglycemia.

5. One drug can alter the absorption of another drug. One drug increases intestinal motility. Which effect does this have on the second drug?

• A. None; absorption of the second drug is not affected.
• B. The increased gut motility decreases the absorption of the second drug.
• C. The absorption of the second drug cannot be predicted.
• D. Less of the second drug is absorbed.

Correct answer: D

Rationale: When one drug increases intestinal motility, it accelerates the movement of the second drug through the system. Since most oral medications are absorbed in the intestine, the faster transit time decreases the absorption of the second drug. Therefore, less of the second drug is absorbed. Choice A is incorrect because the increased gut motility does affect the absorption of the second drug. Choice C is incorrect as the effect of increased intestinal motility on drug absorption can be predicted based on pharmacokinetic principles. Choice B is incorrect as increased gut motility would not increase but decrease the absorption of the second drug.
