Nursing Elites

1. After an older client receives treatment for drug toxicity, the healthcare provider prescribes a 24-hour creatinine clearance test. Before starting the urine collection, the nurse noted that the client's serum creatinine was 0.3 mg/dL. Which action should the nurse implement?

• A. Check the client's urine output hourly
• B. Instruct the client to increase fluid intake
• C. Notify the healthcare provider of the results
• D. Start the 24-hour urine collection

Correct answer: C

Rationale: A serum creatinine level of 0.3 mg/dL is abnormally low, indicating potential issues with the interpretation of the creatinine clearance test. It is crucial for the nurse to notify the healthcare provider of this result before proceeding with the 24-hour urine collection. Checking urine output, instructing the client to increase fluid intake, or starting the urine collection without consulting the healthcare provider could lead to incorrect test results and misinterpretation of the client's renal function.

2. A toddler presenting with a history of intermittent skin rashes, hives, abdominal pain, and vomiting that occurs after ingesting milk products arrives at the clinic accompanied by the parents. Which type of testing should the nurse educate the toddler's family about?

• A. Complete blood count
• B. Lactose tolerance test
• C. Skin allergy testing
• D. Serum immunoglobulin E

Correct answer: D

Rationale: The correct answer is D, Serum immunoglobulin E (IgE) testing. This test can help diagnose food allergies, including milk protein allergies, in toddlers presenting with symptoms like skin rashes, hives, abdominal pain, and vomiting after consuming milk products. Skin allergy testing is used for allergies but may not be suitable for this age group due to developmental factors. Lactose intolerance, which is different from a milk allergy, is assessed through a lactose tolerance test, not IgE testing. A complete blood count (CBC) would not provide specific information related to food allergies.

3. The nurse is caring for a client with chronic heart failure who is receiving digoxin therapy. The nurse reviews the client's lab results and notes that the serum potassium level is 3.0 mEq/L. What action should the nurse take next?

• A. Administer a potassium supplement
• B. Notify the healthcare provider
• C. Hold the next dose of digoxin
• D. Increase dietary potassium intake

Correct answer: C

Rationale: In clients receiving digoxin therapy, low potassium levels can increase the risk of digoxin toxicity. Therefore, when the nurse notes a serum potassium level of 3.0 mEq/L, it is crucial to hold the next dose of digoxin. Notifying the healthcare provider is essential to ensure appropriate interventions, such as potassium supplementation, can be implemented. Administering a potassium supplement without healthcare provider guidance may lead to rapid potassium level changes and potential adverse effects. Increasing dietary potassium intake alone may not promptly address the low serum potassium level in this acute situation.

4. A client with hypothyroidism is prescribed levothyroxine. What assessment finding suggests the medication is effective?

• A. Improved tolerance to cold.
• B. Decreased fatigue and improved energy levels.
• C. Reduced anxiety and improved mood.
• D. Increased sensitivity to heat.

Correct answer: B

Rationale: The correct answer is B: Decreased fatigue and improved energy levels. Levothyroxine is a medication used to treat hypothyroidism by providing the body with the thyroid hormone it lacks. Therefore, a positive response to the medication would manifest as decreased fatigue and improved energy levels due to the correction of the thyroid hormone imbalance. Choices A, C, and D are incorrect because improved tolerance to cold, reduced anxiety, and increased sensitivity to heat are not direct indicators of the effectiveness of levothyroxine in managing hypothyroidism.

5. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?

• A. Losartan
• B. Spironolactone
• C. Metoprolol
• D. Furosemide

Correct answer: B

Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.
