Nursing Elites

1. A nurse is providing client education regarding lithium therapy. Which of the following instructions should the nurse include?

• A. Take with food to decrease nausea
• B. Avoid excessive intake of caffeinated beverages
• C. Monitor for signs of dehydration
• D. Restrict salt intake to prevent water retention

Correct answer: B

Rationale: The correct answer is B. The nurse should instruct the client to avoid excessive intake of caffeinated beverages as they can interfere with lithium levels. Option A is incorrect as lithium is usually recommended to be taken on an empty stomach. Option C is not directly related to lithium therapy. Option D is not a typical instruction for lithium therapy.

2. A client has been prescribed vasopressin for the treatment of diabetes insipidus. What is the expected pharmacologic action of this medication?

• A. To stimulate the pancreas to secrete insulin
• B. To slow the absorption of glucose in the intestine
• C. To increase reabsorption of water in the renal tubules
• D. To increase blood pressure

Correct answer: C

Rationale: The correct answer is C: To increase reabsorption of water in the renal tubules. Vasopressin, also known as antidiuretic hormone (ADH), works by increasing the reabsorption of water in the renal tubules, which helps to concentrate urine and reduce excessive urination in diabetes insipidus. Choice A is incorrect as vasopressin does not stimulate the pancreas to secrete insulin. Choice B is incorrect as vasopressin does not affect the absorption of glucose in the intestine. Choice D is incorrect as vasopressin's primary action is not to increase blood pressure, although it can have some vasoconstrictive effects.

3. A nurse has provided education to a client regarding prescribed levothyroxine sodium. Which of the following client statements demonstrates understanding of medication administration?

• A. I should take my medication as needed to alleviate symptoms
• B. I should take the medication in divided doses to ensure therapeutic drug levels
• C. I should take the medication in the morning to prevent insomnia
• D. I should take the medication on a full stomach

Correct answer: C

Rationale: Levothyroxine should be taken once in the morning to prevent insomnia and maintain therapeutic levels.

4. A client with an artificial heart valve is prescribed warfarin therapy. Which of the following laboratory values should the nurse monitor to assess the therapeutic effect of warfarin?

• A. Hemoglobin (Hgb)
• B. Prothrombin time (PT)
• C. Bleeding time
• D. Activated partial thromboplastin time (aPTT)

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT). Warfarin is an anticoagulant medication that works by inhibiting the clotting factors dependent on vitamin K, such as factors II, VII, IX, and X. The prothrombin time (PT) measures the extrinsic pathway and is used to monitor the therapeutic effects of warfarin therapy. Monitoring PT helps assess the time it takes for the blood to clot, ensuring that the anticoagulant effect is within the desired range. Choices A, C, and D are incorrect because hemoglobin (Hgb) measures the amount of hemoglobin in the blood, bleeding time assesses the time it takes for bleeding to stop, and activated partial thromboplastin time (aPTT) is used to monitor heparin therapy, not warfarin therapy.

5. When administering amlodipine to a client with hypertension, what adverse effect should the nurse monitor for?

• A. Constipation
• B. Facial flushing
• C. Hypotension
• D. Jaundice

Correct answer: C

Rationale: The correct answer is C, Hypotension. Amlodipine is a calcium channel blocker commonly used to treat hypertension. One of the main adverse effects of amlodipine is hypotension, leading to low blood pressure. The nurse should monitor the client for signs of hypotension such as dizziness, lightheadedness, or fainting. Choices A, B, and D are incorrect because constipation, facial flushing, and jaundice are not typically associated with amlodipine administration.
