Nursing Elites

1. Your patient has a blood potassium level of 9.2 mEq/L. What intervention should you anticipate for this patient?

• A. Intravenous potassium supplementation
• B. Intravenous calcium supplementation
• C. Kidney dialysis
• D. Parenteral nutrition

Correct answer: C

Rationale: The correct answer is C: Kidney dialysis. A blood potassium level of 9.2 mEq/L indicates severe hyperkalemia, which can be life-threatening. Kidney dialysis is the most appropriate intervention to rapidly lower potassium levels in this situation. Choice A, intravenous potassium supplementation, would worsen the hyperkalemia. Choice B, intravenous calcium supplementation, is not the primary intervention for hyperkalemia. Choice D, parenteral nutrition, is unrelated to treating hyperkalemia and would not address the immediate concern.

2. Based on the signs and symptoms of erythema marginatum, Sydenham chorea, epistaxis, abdominal pain, fever, cardiac problems, and skin nodules in your 32-year-old female patient, what disorder would you most likely suspect?

• A. Leukemia
• B. Histoplasmosis
• C. Pneumocystis jiroveci
• D. Rheumatoid arthritis

Correct answer: D

Rationale: The signs and symptoms described point towards rheumatoid arthritis. Erythema marginatum, Sydenham chorea, epistaxis, abdominal pain, fever, cardiac issues, and skin nodules are classic manifestations of rheumatic fever, which is a complication of untreated streptococcal infection. This condition can lead to rheumatoid arthritis over time. Choices A, B, and C are incorrect as they do not align with the provided signs and symptoms, and they are not associated with the clinical presentation described.

3. A nurse reviews a client's laboratory report and notes that the client's serum phosphorus level is 2.0 mg/dL. Which condition most likely caused this serum phosphorus level?

• A. Alcoholism
• B. Renal insufficiency
• C. Hypoparathyroidism
• D. Tumor lysis syndrome

Correct answer: A

Rationale: The correct answer is A: Alcoholism. Alcoholism can lead to hypophosphatemia due to poor dietary intake and other factors. Excessive alcohol consumption can result in malnutrition, particularly a deficiency in phosphorus. Choices B, C, and D are unlikely to cause low serum phosphorus levels. Renal insufficiency is more likely to cause hyperphosphatemia, hypoparathyroidism is associated with hypocalcemia rather than hypophosphatemia, and tumor lysis syndrome typically presents with hyperphosphatemia due to the release of intracellular phosphate.

4. Dr. Shrunk orders intravenous (IV) insulin for Rita, a client with a blood sugar of 563. Nurse AJ administers insulin lispro (Humalog) intravenously (IV). What does the best evaluation of the nurse reveal? Select one that does not apply.

• A. The nurse could have given the insulin subcutaneously.
• B. The nurse did not have to contact the physician.
• C. The nurse should have used regular insulin (Humulin R).
• D. The nurse used the correct insulin.

Correct answer: C

Rationale: The best evaluation of the nurse reveals that she should have used regular insulin (Humulin R) for IV administration. Regular insulin is the only insulin approved for intravenous administration due to its pharmacokinetic properties. Insulin lispro (Humalog) is not suitable for IV use. Choice A is incorrect because giving insulin intravenously is necessary in this case of high blood sugar. Choice B is incorrect because administering a different insulin without consulting the physician is not appropriate. Choice D is incorrect because the nurse used the incorrect insulin, which could pose risks to the client's health.

5. Which manifestation should the nurse expect to assess in a patient with fluid volume deficit?

• A. Headache and muscle cramps
• B. Dyspnea and respiratory crackles
• C. Increased pulse rate and blood pressure
• D. Orthostatic hypotension and flat neck veins

Correct answer: D

Rationale: Orthostatic hypotension and flat neck veins are classic manifestations of fluid volume deficit. When the body loses fluid, blood volume decreases, leading to decreased venous return to the heart, resulting in orthostatic hypotension and flat neck veins. Choices A, B, and C are more indicative of other conditions such as dehydration, respiratory issues, or compensatory mechanisms in response to hypovolemia, respectively.
