1. Which of the following statements is true about ischemic colitis?

• A. Typically requires colonic resection
• B. Affects the watershed areas of the colon, namely, the splenic flexure, right colon, and rectum
• C. Is only seen in the elderly
• D. Requires colonoscopic intervention

Correct answer: B

Rationale: Ischemic colitis most often results from low-flow states associated with hypotension or poor perfusion. As a result, the vascular watershed areas of the colon, including the splenic flexure, right colon, and rectum, are at highest risk of ischemic injury. Therefore, option B is correct as it accurately identifies the areas commonly affected by ischemic colitis.

2. Your patient has an order to receive Levothyroxine Sodium 75 mcg daily IV. You have a vial containing 100 mcg available from the pharmacy. According to the package insert, 5 mL of 0.9% sodium chloride is needed to reconstitute. You add the appropriate amount of sodium chloride to the vial. How many mcg of medication are in 1 mL of the vial?

• A. 20 mcg
• B. 15 mcg
• C. 25 mcg
• D. 30 mcg

Correct answer: A

Rationale: After reconstitution, the concentration of Levothyroxine Sodium in the vial is 100 mcg in 5 mL, which equals 20 mcg/mL. Therefore, in 1 mL of the vial, there are 20 mcg of medication.

3. In a client with liver cirrhosis experiencing confusion and disorientation, what condition is most likely causing these symptoms?

• A. Hepatic encephalopathy
• B. Hypoglycemia
• C. Electrolyte imbalance
• D. Dehydration

Correct answer: A

Rationale: Hepatic encephalopathy is the most likely condition causing confusion and disorientation in a client with liver cirrhosis. This condition is a common complication of liver cirrhosis and is characterized by cognitive impairment due to elevated ammonia levels in the blood. The build-up of ammonia affects brain function, leading to symptoms such as confusion, disorientation, and altered consciousness. Hypoglycemia (choice B) may present with confusion but is less likely in a client with liver cirrhosis without a history of diabetes or insulin use. Electrolyte imbalance (choice C) and dehydration (choice D) can contribute to confusion but are not the primary causes in a client with liver cirrhosis experiencing these symptoms.

4. A client with peptic ulcer disease is prescribed ranitidine (Zantac). Which statement by the client indicates the need for further teaching?

• A. I will take this medication at bedtime.
• B. I need to avoid smoking while taking this medication.
• C. I should take this medication with meals.
• D. This medication will help reduce stomach acid.

Correct answer: C

Rationale: The client's statement that they should take ranitidine with meals indicates a need for further teaching. Ranitidine is typically taken at bedtime or before meals to be most effective in reducing stomach acid. Taking it with meals may not provide the optimal therapeutic effect.

5. A client with newly diagnosed diabetes mellitus is being discharged home. Which statement indicates the client understands the instructions about managing blood glucose levels?

• A. I will test my blood glucose level once a week.
• B. I should eat a snack if my blood glucose is 70 mg/dl.
• C. If I feel shaky, I should take another dose of insulin.
• D. It's okay to skip a meal if I'm not hungry.

Correct answer: B

Rationale: Choice B is the correct answer. Eating a snack when blood glucose is low (70 mg/dl) can help prevent hypoglycemia. It is important for clients with diabetes to manage their blood glucose levels to prevent complications, and consuming a snack when glucose levels drop can help maintain the balance.
