Nursing Elites

1. A nurse is teaching a client who has a new prescription for Spironolactone. Which of the following adverse effects should the nurse instruct the client to monitor?

• A. Hyperkalemia
• B. Hypoglycemia
• C. Hypocalcemia
• D. Hyponatremia

Correct answer: A

Rationale: Spironolactone is a potassium-sparing diuretic, so the nurse should monitor the client for hyperkalemia, which can cause muscle weakness and cardiac dysrhythmias.

2. A healthcare provider 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 dextrose 5% in water (D5W) over 6 hours. Choice B, 100 mL/hr, is incorrect as it does not match the correct calculation. Choice C, 150 mL/hr, is incorrect as it is higher than the calculated flow rate. Choice D, 200 mL/hr, is incorrect as it is also higher than the calculated flow rate.

3. A client has a new prescription for Warfarin. Which of the following instructions should the nurse include?

• A. Monitor for signs of bleeding.
• B. Avoid foods high in vitamin K.
• C. Expect to have increased urination.
• D. Take the medication with an antacid.

Correct answer: A

Rationale: The correct instruction for a client starting Warfarin is to monitor for signs of bleeding. Warfarin is an anticoagulant that increases the risk of bleeding; therefore, it is crucial for the client to watch for any signs of bleeding, such as easy bruising, prolonged bleeding from cuts, blood in urine or stools, or unusual bleeding from gums or nose. If any of these signs occur, the client should promptly report them to their healthcare provider for further evaluation and management. Choices B, C, and D are incorrect because avoiding foods high in vitamin K is related to other medications like Coumadin, increased urination is not a common side effect of Warfarin, and taking Warfarin with an antacid can potentially interfere with its absorption.

4. A healthcare professional working in an emergency department is caring for a client who has Benzodiazepine toxicity due to an overdose. Which of the following actions is the healthcare professional's priority?

• A. Administer flumazenil.
• B. Identify the client's level of orientation.
• C. Infuse IV fluids.
• D. Prepare the client for gastric lavage.

Correct answer: B

Rationale: When managing a client with Benzodiazepine toxicity, the priority action for the healthcare professional is to assess the client. Identifying the client's level of orientation allows the healthcare professional to understand the client's cognitive status, which is crucial for further interventions and decision-making in the care plan. Administering flumazenil (Choice A) may precipitate withdrawal symptoms and should be done cautiously. Infusing IV fluids (Choice C) can be important but is not the priority over assessing the client. Gastric lavage (Choice D) is not typically recommended due to the risk of complications and its limited effectiveness in cases of Benzodiazepine overdose.

5. What is the pharmacological action of metformin?

• A. Blocks stimulation of beta1 and beta2.
• B. Blocks vasoconstriction and aldosterone.
• C. Acts at many levels in the CNS to produce an anxiolytic effect.
• D. Decreases hepatic glucose production.

Correct answer: D

Rationale: The correct answer is D: Decreases hepatic glucose production. Metformin's primary pharmacological action is to decrease hepatic glucose production, leading to lower blood sugar levels and improved insulin sensitivity in the liver. Choices A, B, and C are incorrect because metformin does not block stimulation of beta1 and beta2 receptors, vasoconstriction, aldosterone, or act in the CNS to produce an anxiolytic effect. Therefore, these options are not reflective of metformin's mechanism of action.
