Nursing Elites

1. The healthcare provider notes a blood pressure of 160/90 mm Hg in a patient taking a thiazide diuretic. The patient reports taking an herbal medication that a friend recommended. Which herbal product is likely, given this patient’s blood pressure?

• A. Ginkgo
• B. Hawthorn
• C. Licorice
• D. St. John’s wort

Correct answer: A

Rationale: The correct answer is A: Ginkgo. Increased blood pressure can result when ginkgo is used in combination with a thiazide diuretic. Option B (Hawthorn) is incorrect because hawthorn is more commonly associated with lowering blood pressure. Option C (Licorice) is incorrect because licorice can lead to sodium and water retention, potentially exacerbating hypertension. Option D (St. John’s wort) is incorrect as it is not typically associated with significant blood pressure effects.

2. A client with chronic renal failure is prescribed a low-protein diet. The nurse should explain to the client that the purpose of this diet is to:

• A. Prevent fluid overload.
• B. Reduce the workload on the kidneys.
• C. Prevent dehydration.
• D. Maintain electrolyte balance.

Correct answer: B

Rationale: The correct answer is B: 'Reduce the workload on the kidneys.' A low-protein diet is prescribed for clients with chronic renal failure to decrease the production of urea and other nitrogenous wastes, which can accumulate in the body when the kidneys are not functioning properly. This reduction in protein intake helps to lessen the burden on the kidneys, as they may have difficulty in filtering and excreting waste products. Choice A is incorrect because fluid overload is more related to restrictions in fluid intake rather than protein intake. Choice C is incorrect as a low-protein diet does not directly prevent dehydration. Choice D is incorrect because while electrolyte balance is essential in renal failure, the primary purpose of a low-protein diet is to reduce the workload on the kidneys by limiting the production of waste products.

3. The nurse is teaching the main principles of hemodialysis to a client with chronic kidney disease. Which statement by the client indicates a need for further teaching by the nurse?

• A. My sodium level changes due to the movement from the blood into the dialysate.
• B. Dialysis works by the movement of wastes from higher to lower concentration.
• C. Extra fluid can be pulled from the blood by osmosis.
• D. The dialysate is similar to blood but without any toxins.

Correct answer: B

Rationale: The correct answer is B because dialysis works by the movement of solutes from an area of higher concentration to an area of lower concentration, which is known as diffusion. The other statements are accurate: A correctly describes the movement of sodium during hemodialysis, C explains the removal of excess fluid by osmosis, and D highlights the purpose of the dialysate in removing toxins from the blood.

4. The nurse is caring for a patient who has recurrent urinary tract infections. The patient’s current infection is not responding to an antibiotic that has been used successfully several times in the past. The nurse understands that this is most likely due to

• A. acquired bacterial resistance.
• B. cross-resistance.
• C. inherent bacterial resistance.
• D. transferred resistance.

Correct answer: A

Rationale: The correct answer is A: acquired bacterial resistance. Acquired resistance happens when an organism has been exposed to the antibacterial drug, making it less effective over time. Cross-resistance (B) occurs when resistance to one drug leads to resistance to another. Inherent resistance (C) happens without prior exposure to the drug, meaning the bacteria are naturally resistant. Transferred resistance (D) involves the transfer of resistant genes from one organism to another, contributing to resistance development.

5. The client with chronic renal failure is being educated about the importance of a low-sodium diet. Which of the following statements by the client indicates a need for further teaching?

• A. I can eat canned vegetables as long as I rinse them first.
• B. I can use table salt sparingly.
• C. I can eat frozen dinners if they are labeled low-sodium.
• D. I can eat whatever I want as long as I avoid salty foods.

Correct answer: B

Rationale: The correct answer is B. Clients with chronic renal failure need to strictly limit their sodium intake. Advising the client to use table salt sparingly is incorrect as they should avoid table salt altogether to adhere to a low-sodium diet. Choice A is correct as rinsing canned vegetables can help reduce their sodium content. Choice C is correct as consuming frozen dinners labeled low-sodium can be a suitable option. Choice D is incorrect as it implies that avoiding only salty foods is sufficient, when in fact, overall sodium intake needs to be monitored closely.
