Nursing Elites

1. A client is receiving heparin to treat a deep vein thrombosis. The nurse should monitor which laboratory result to assist in evaluating the efficacy of the drug?

• A. Platelet count
• B. Prothrombin time
• C. Partial thromboplastin time
• D. Serum levels of protamine sulfate

Correct answer: C

Rationale: The nurse should monitor the partial thromboplastin time to evaluate the efficacy of heparin. Partial thromboplastin time reflects the anticoagulant effect of heparin by measuring the intrinsic pathway of coagulation. Platelet count assesses platelet levels and is not specific to heparin efficacy. Prothrombin time is used to monitor warfarin therapy. Serum levels of protamine sulfate are not used to evaluate the efficacy of heparin.

2. 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.

3. 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.

4. The nurse is caring for a patient with short-term persistent diarrhea. Which class of medication would the nurse anticipate giving?

• A. Lubricants
• B. Probiotics
• C. Adsorbents
• D. Anticholinergics

Correct answer: B

Rationale: Probiotics are the correct choice in this scenario as they help restore normal gut flora, which can be effective in treating diarrhea by promoting a healthy balance of bacteria in the intestines. Lubricants are used to ease bowel movements and are not indicated for treating diarrhea. Adsorbents work by binding to toxins in the gut, which is not the primary mechanism needed for treating diarrhea. Anticholinergics are more commonly used for conditions like overactive bladder and not for short-term persistent diarrhea.

5. What is the primary nursing intervention that the practical nurse should perform before administering ampicillin to a client diagnosed with a urinary tract infection?

• A. Obtain a clean-catch urine specimen.
• B. Assess the urine pH for acidity.
• C. Insert an indwelling catheter.
• D. Assess for complaints of dysuria.

Correct answer: A

Rationale: The correct answer is to obtain a clean-catch urine specimen. Before administering ampicillin to a client with a urinary tract infection, it is crucial to collect a urine specimen to determine the causative organism and evaluate the effectiveness of pharmacological therapy. Assessing the urine pH for acidity (choice B) is not the primary intervention needed before administering ampicillin. Inserting an indwelling catheter (choice C) is invasive and not necessary unless indicated for specific reasons. Assessing for complaints of dysuria (choice D) is important but does not take precedence over obtaining a urine specimen for proper diagnosis and treatment.
