Nursing Elites

1. A client with a history of heart failure is prescribed carvedilol. The nurse should monitor for which potential side effect?

• A. Bradycardia
• B. Tachycardia
• C. Hypertension
• D. Hyperglycemia

Correct answer: A

Rationale: When a client is prescribed carvedilol, the nurse should monitor for bradycardia, a potential side effect of this medication. Carvedilol is a beta-blocker that can slow down the heart rate, so monitoring for signs of bradycardia is essential to prevent any adverse effects on the client's cardiovascular system. Tachycardia (Choice B) is less likely to occur with carvedilol since it primarily works to reduce heart rate. Hypertension (Choice C) and hyperglycemia (Choice D) are not common side effects associated with carvedilol.

2. What class of laxative would the nurse recommend to a patient asking about the best way to prevent constipation?

• A. Stimulant laxatives
• B. Bulk-forming laxatives
• C. Emollient laxatives
• D. Hyperosmotic laxatives

Correct answer: B

Rationale: The correct answer is B: Bulk-forming laxatives. These laxatives are recommended to prevent constipation because they work by absorbing liquid in the intestines, forming a bulky, soft stool that is easier to pass. They are safe and considered the most natural option. Stimulant laxatives (choice A) work by promoting bowel movements through intestinal contractions and are more suitable for treating occasional constipation rather than preventing it. Emollient laxatives (choice C) soften the stool by increasing the incorporation of water into the feces and are more suitable for patients who need to avoid straining during defecation. Hyperosmotic laxatives (choice D) work by drawing water into the intestine through osmosis and are typically used for more severe cases of constipation, not for prevention.

3. A client who received a renal transplant three months ago is readmitted to the acute care unit with signs of graft rejection. While taking the client's history, the nurse determines the client has been self-administering St. John's wort, an herbal preparation, on the advice of a friend. What information is most significant about this finding?

• A. Wort can decrease plasma concentration of Cyclospora
• B. Wort can decrease plasma concentration of Tacrolimus
• C. Wort can decrease plasma concentration of Cyclosporine
• D. Wort can decrease plasma concentration of Mycophenolate

Correct answer: C

Rationale: The most significant information about the client self-administering St. John's wort, an herbal preparation, is that it can decrease the plasma concentration of Cyclosporine. St. John's wort is known to reduce the efficacy of Cyclosporine, which is a common immunosuppressant drug used to prevent transplant rejection. Choices A, B, and D are incorrect because St. John's wort does not affect the plasma concentration of Cyclospora, Tacrolimus, or Mycophenolate.

4. The client is receiving vancomycin, and the nurse plans to draw blood for a peak and trough to determine... the best timing for these levels?

• A. Midway through administration of the IV dose and 30 minutes before the next
• B. Two hours after completion of the IV dose and 30 minutes before the next
• C. Two hours after completion of the IV dose and one hour before the next
• D. Immediately after completion of the IV dose and 30 minutes before

Correct answer: B

Rationale: To accurately determine peak and trough levels of vancomycin, blood should be drawn two hours after the completion of the IV dose and 30 minutes before the next dose. This timing allows for appropriate assessment of the drug levels in the body, ensuring accurate monitoring of therapeutic and toxic concentrations. Choice A is incorrect as drawing blood midway through administration does not provide an accurate peak level. Choice C is incorrect as drawing blood one hour before the next dose does not represent the trough level. Choice D is incorrect because drawing blood immediately after completion of the IV dose does not allow enough time for the drug to reach peak levels.

5. A client with a history of heart failure is prescribed carvedilol. The nurse should monitor the client for which adverse effect?

• A. Dizziness upon standing
• B. Weight loss
• C. Bradycardia
• D. Hypotension

Correct answer: D

Rationale: The correct answer is D: Hypotension. Carvedilol, a beta-blocker, can lead to hypotension by blocking the effects of adrenaline, which can cause blood vessels to dilate and reduce blood pressure. While dizziness upon standing is a potential adverse effect of carvedilol, it is more specifically related to orthostatic hypotension, which is a form of hypotension that occurs when a person stands up from a sitting or lying position. Weight loss and bradycardia are not typically associated with carvedilol use. Therefore, the nurse should primarily monitor for hypotension in a client taking carvedilol.
