Nursing Elites

1. The nurse is caring for a client with chronic renal failure who is on a low-potassium diet. Which of the following foods should the client avoid?

• A. Bananas
• B. Potatoes
• C. Rice
• D. Apples

Correct answer: A

Rationale: Bananas are high in potassium content, which can lead to hyperkalemia in clients with chronic renal failure who are on a low-potassium diet. Therefore, it is crucial for these clients to avoid bananas. Potatoes, rice, and apples are lower in potassium compared to bananas and are generally considered safe for consumption in clients with chronic renal failure on a low-potassium diet.

2. Which of the following is a characteristic symptom of hypothyroidism?

• A. Fatigue.
• B. Weight gain.
• C. Cold intolerance.
• D. Heat intolerance.

Correct answer: C

Rationale: The correct answer is 'Cold intolerance.' Hypothyroidism is associated with a decreased metabolic rate, leading to a decreased ability to regulate body temperature and a feeling of being cold. Fatigue (Choice A) and weight gain (Choice B) are also common symptoms of hypothyroidism due to the overall slowing down of bodily functions. Heat intolerance (Choice D) is more commonly associated with hyperthyroidism, where the body's metabolism is overactive, leading to increased heat production.

3. Polyethylene glycol–electrolyte solution (GoLYTELY) is prescribed for a hospitalized client scheduled for a colonoscopy. The client begins to experience diarrhea after drinking the solution. Which action by the nurse is appropriate?

• A. Calling the physician
• B. Administering a cleansing enema
• C. Documenting the diarrhea in the medical record
• D. Giving intravenous replacement fluids in large amounts

Correct answer: C

Rationale: The correct action by the nurse in this situation is to document the diarrhea in the medical record. Polyethylene glycol–electrolyte solution (GoLYTELY) is a bowel evacuant used to cleanse the bowel before a colonoscopy. It is expected to cause mild diarrhea, which is a normal response to the medication. The diarrhea helps clear the bowel in preparation for the procedure. Calling the physician is not necessary unless there are complications. Administering a cleansing enema or giving intravenous replacement fluids in large amounts are not appropriate actions as they are not indicated for managing the expected diarrhea caused by GoLYTELY.

4. A client with renal insufficiency and a low red blood cell count asks, 'Is my anemia related to the renal insufficiency?' How should the nurse respond?

• A. Red blood cells produce erythropoietin, which increases blood flow to the kidneys.
• B. Your anemia and renal insufficiency are related to inadequate vitamin D and a loss of bone density.
• C. Erythropoietin is usually released from the kidneys and stimulates red blood cell production in the bone marrow.
• D. Kidney insufficiency inhibits active transportation of red blood cells throughout the blood.

Correct answer: C

Rationale: The correct answer is C. Erythropoietin is produced in the kidney and is released in response to decreased oxygen tension in the renal blood supply. Erythropoietin stimulates red blood cell production in the bone marrow. Anemia in renal insufficiency is often due to decreased erythropoietin production. Anemia and renal insufficiency are not manifestations of vitamin D deficiency as stated in choice B. Choice A is incorrect as erythropoietin does not increase blood flow to the kidneys. Choice D is incorrect because kidney insufficiency does not inhibit active transportation of red blood cells throughout the blood; rather, it affects erythropoietin production and subsequent red blood cell formation.

5. A client has a long history of hypertension. Which category of medication would the nurse expect to be ordered to avoid chronic kidney disease (CKD)?

• A. Antibiotic
• B. Histamine blocker
• C. Bronchodilator
• D. Angiotensin-converting enzyme (ACE) inhibitor

Correct answer: D

Rationale: The correct answer is D, Angiotensin-converting enzyme (ACE) inhibitor. ACE inhibitors inhibit the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. By blocking this conversion, ACE inhibitors promote vasodilation and improve perfusion to the kidneys. Additionally, ACE inhibitors block the breakdown of bradykinin and prostaglandin, further contributing to vasodilation. They also lead to increased renin and decreased aldosterone levels. These effects help in reducing blood pressure and protecting the kidneys in clients with hypertension. Antibiotics are used to fight infections, histamine blockers reduce inflammation, and bronchodilators widen the bronchi, none of which address the underlying processes involved in slowing the progression of chronic kidney disease (CKD) in hypertensive clients.
