Nursing Elites

1. The nurse is caring for a client with diabetic ketoacidosis (DKA). Which laboratory value requires immediate intervention?

• A. Serum glucose of 300 mg/dL
• B. Serum potassium of 4.5 mEq/L
• C. Serum bicarbonate of 15 mEq/L
• D. Serum pH of 7.28

Correct answer: D

Rationale: A serum pH of 7.28 indicates metabolic acidosis in a client with diabetic ketoacidosis (DKA), requiring immediate intervention. In DKA, the body produces excess ketones, leading to acidosis. Monitoring and correcting the pH level is crucial in managing DKA. Serum glucose levels may be high in DKA, but the immediate concern is correcting the acidosis to prevent complications. Serum potassium and bicarbonate levels are also important but not as immediately critical as correcting the acidosis in DKA.

2. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be closely monitored?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum sodium level of 135 mEq/L

Correct answer: A

Rationale: The correct answer is A: Serum potassium level. In clients receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin therapy can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium levels helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant for assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical due to the potential adverse effects of elevated potassium levels in CKD patients on this therapy.

3. A 7-year-old boy is brought to the clinic because of facial edema. He reports that he has been voiding small amounts of dark, cloudy, tea-colored urine. The parents state that their son had a sore throat 2 weeks earlier, but it has resolved. After assessing the child's vital signs and weight, what intervention should the nurse implement next?

• A. Perform an otoscopic examination
• B. Measure the child's abdominal girth
• C. Collect a urine specimen for routine urinalysis
• D. Obtain a blood specimen for serum electrolytes

Correct answer: C

Rationale: Collecting a urine specimen for routine urinalysis is the next appropriate intervention. The symptoms described, including facial edema and tea-colored urine, are indicative of glomerulonephritis, a condition affecting the kidneys. A urine specimen can help assess renal function and the presence of blood and protein in the urine, which are common in glomerulonephritis. Performing an otoscopic examination (Choice A) is not relevant to the presenting symptoms. Measuring the child's abdominal girth (Choice B) is not necessary at this point as it does not directly address the urinary symptoms. Obtaining a blood specimen for serum electrolytes (Choice D) may provide information about electrolyte imbalances but is not the most appropriate initial step in this case.

4. Which breakfast selection indicates that the client understands the nurse's instructions about the dietary management of osteoporosis?

• A. Egg whites, toast, and coffee.
• B. Bran muffin, mixed fruits, and orange juice.
• C. Granola and grapefruit juice.
• D. Bagel with jelly and skim milk.

Correct answer: D

Rationale: The correct answer is D, 'Bagel with jelly and skim milk.' This choice includes skim milk, a good source of calcium, which is important for osteoporosis management. It also avoids foods that inhibit calcium absorption. Osteoporosis dietary management emphasizes increased calcium intake and reducing foods that hinder calcium absorption. Choice A only provides proteins but lacks calcium. Choice B offers fruits and a bran muffin, but it lacks a good source of calcium. Choice C has granola but misses a significant source of calcium.

5. A client with a head injury is receiving mechanical ventilation. Which finding indicates to the nurse that the client may be experiencing increased intracranial pressure (ICP)?

• A. Widening pulse pressure
• B. Sudden drop in heart rate
• C. A decrease in urine output
• D. Elevated blood pressure and widening pulse pressure

Correct answer: D

Rationale: In a client with increased intracranial pressure (ICP), the body's compensatory mechanisms lead to an elevation in blood pressure and a widening pulse pressure. This occurs due to the body's attempt to maintain cerebral perfusion. Therefore, elevated blood pressure and widening pulse pressure are classic signs of increased ICP and necessitate immediate attention. Choices A, B, and C are incorrect because a widening pulse pressure, sudden drop in heart rate, or decreased urine output are not specific indicators of increased ICP.
