1. A healthcare professional is preparing to administer dextrose 5% in water (D5W) 750 mL IV to infuse over 6 hr. How many mL/hr should the IV pump be set to deliver?

• A. 125 mL/hr
• B. 100 mL/hr
• C. 150 mL/hr
• D. 200 mL/hr

Correct answer: A

Rationale: To calculate the flow rate, divide the total volume by the total time: 750 mL / 6 hr = 125 mL/hr. Therefore, the IV pump should be set to deliver 125 mL/hr to infuse D5W 750 mL over 6 hours. Choice B (100 mL/hr) is incorrect because it does not accurately divide the total volume by the total time. Choice C (150 mL/hr) and Choice D (200 mL/hr) are incorrect as they are not the correct flow rates needed to infuse the D5W solution over the specified time period.

2. A client has a prescription for Furosemide. Which of the following instructions should the nurse include?

• A. Take the medication in the morning.
• B. Increase your intake of potassium-rich foods.
• C. Expect your urine to turn orange.
• D. Avoid prolonged sunlight exposure.

Correct answer: B

Rationale: The correct answer is B: 'Increase your intake of potassium-rich foods.' Furosemide is a loop diuretic that can lead to hypokalemia (low potassium levels) due to increased excretion of potassium in the urine. To counteract this effect and maintain electrolyte balance, the client should be advised to increase their intake of potassium-rich foods. This instruction helps prevent potential complications associated with low potassium levels. Choices A, C, and D are incorrect. Taking Furosemide in the morning does not affect its effectiveness; urine turning orange is not an expected side effect of Furosemide; and avoiding prolonged sunlight exposure is not directly related to Furosemide use.

3. A client has been prescribed Aspirin for prevention of cardiovascular disease. Which of the following findings indicates the medication is effective?

• A. The client has a decrease in troponin levels.
• B. The client has a regular heart rhythm.
• C. The client experiences a decrease in episodes of angina.
• D. The client's blood pressure remains stable.

Correct answer: C

Rationale: The correct answer is C. A decrease in episodes of angina indicates that Aspirin is effectively preventing the formation of clots that could lead to cardiovascular events. Angina is chest pain or discomfort caused by reduced blood flow to the heart muscle, usually due to coronary artery disease. Aspirin works by inhibiting platelet aggregation, thereby reducing the risk of clot formation in the arteries. Improvement in angina symptoms suggests that the medication is successfully preventing clot-related complications in the cardiovascular system. Monitoring and recognizing a decrease in angina episodes can be a valuable indicator of the medication's efficacy in preventing cardiovascular events. Choices A, B, and D are incorrect because a decrease in troponin levels, a regular heart rhythm, or stable blood pressure, while important parameters, do not directly reflect the effectiveness of Aspirin in preventing cardiovascular events through antiplatelet action.

4. A client with cancer is prescribed methotrexate. Which supplement should the healthcare provider recommend to reduce the risk of methotrexate toxicity?

• A. Folic acid
• B. Magnesium
• C. Vitamin D
• D. Iron

Correct answer: A

Rationale: The correct answer is folic acid. Methotrexate is a folic acid antagonist, and supplementing with folic acid can help reduce the risk of methotrexate toxicity. Folic acid supplementation is commonly recommended to counteract the effects of methotrexate on folate metabolism. Magnesium, Vitamin D, and Iron are not specifically indicated to reduce the risk of methotrexate toxicity and therefore are incorrect choices in this scenario.

5. A drug ending in the suffix (tidine) is considered a ______.

• A. Antidepressant
• B. Protease inhibitor
• C. Beta antagonist
• D. H antagonist

Correct answer: D

Rationale: Drugs ending in -tidine are histamine (H2) receptor antagonists, which block the action of histamine at the H2 receptors, commonly used to reduce stomach acid production. Therefore, the correct answer is an 'H antagonist.' It is essential to be familiar with drug suffixes as they can provide clues to the drug's class and function.
