Nursing Elites

1. Which clients are at risk for kidney problems? (Select all that apply.)

• A. Clients taking synthetic creatine supplements
• B. Clients taking metformin for diabetes mellitus
• C. Clients taking high-dose nonsteroidal anti-inflammatory drugs (NSAIDs) for chronic back pain
• D. Clients taking prenatal vitamins and using albuterol nebulizers

Correct answer: A

Rationale: Clients who take synthetic creatine supplements, metformin, and high-dose or long-term NSAIDs are at risk for kidney dysfunction. Synthetic creatine supplements can cause kidney damage, metformin may rarely cause lactic acidosis leading to renal impairment, and high-dose NSAIDs can lead to acute kidney injury. Prenatal vitamins and albuterol nebulizers are not known to significantly impact kidney function, thus do not pose a risk for kidney problems.

2. Oxygen via nasal cannula has been prescribed for a client with emphysema. The nurse checks the physician’s orders to ensure that the prescribed flow is not greater than:

• A. 1 L/min
• B. 3 L/min
• C. 4 L/min
• D. 6 L/min

Correct answer: B

Rationale: The correct answer is B, 3 L/min. Clients with emphysema typically receive oxygen at a flow rate of 1 to 2 L/min, with a maximum of 3 L/min. Higher flow rates can lead to oxygen toxicity in these clients, so it's crucial to adhere to the prescribed limits. Choice A (1 L/min) is too low and may not provide adequate oxygenation for the client. Choices C (4 L/min) and D (6 L/min) exceed the recommended flow rates for clients with emphysema and can increase the risk of oxygen toxicity.

3. The charge nurse of the medical-surgical unit is making staff assignments. Which staff member should be assigned to a client with chronic kidney disease who is exhibiting a low-grade fever and a pericardial friction rub?

• A. Registered nurse who just floated from the surgical unit
• B. Registered nurse who just floated from the dialysis unit
• C. Registered nurse who was assigned the same client yesterday
• D. Licensed practical nurse with 5 years of experience on this floor

Correct answer: C

Rationale: The client is exhibiting symptoms of pericarditis, which can occur with chronic kidney disease. Continuity of care is crucial to assess subtle changes in clients' conditions. Therefore, the registered nurse (RN) who previously cared for this client should be assigned again. Float nurses may lack knowledge of the unit and its clients, potentially leading to oversight of critical details. The licensed practical nurse, while experienced, may not possess the advanced assessment skills and education level of an RN to effectively evaluate and manage pericarditis in this client.

4. The nurse is caring for a newly admitted patient who will receive digoxin to treat a cardiac dysrhythmia. The patient takes hydrochlorothiazide (HydroDIURIL) and reports regular use of over-the-counter laxatives. Before administering the first dose of digoxin, the nurse will review the patient’s electrolytes with careful attention to the levels of which electrolytes?

• A. Calcium and magnesium
• B. Sodium and calcium
• C. Potassium and chloride
• D. Potassium and magnesium

Correct answer: D

Rationale: Before administering digoxin, the nurse must review the patient's electrolyte levels, focusing on potassium and magnesium. Hypomagnesemia, similar to hypokalemia, can enhance the action of digitalis and lead to digitalis toxicity. Laxatives and diuretics, like hydrochlorothiazide, can deplete both potassium and magnesium. Therefore, monitoring these electrolytes is crucial to prevent potential adverse effects associated with digoxin therapy. Choice A (Calcium and magnesium) is incorrect because calcium levels are not specifically mentioned as crucial for digoxin therapy. Choice B (Sodium and calcium) is incorrect as sodium is not typically monitored in relation to digoxin therapy. Choice C (Potassium and chloride) is incorrect because although potassium is vital, chloride is not typically associated with digoxin therapy.

5. Which is a characteristic that distinguishes sulfonamides from other drugs used to treat bacterial infections?

• A. Sulfonamides are bactericidal.
• B. Sulfonamides are synthetic compounds.
• C. Sulfonamides have antifungal and antiviral properties.
• D. Sulfonamides increase bacterial synthesis of folic acid.

Correct answer: B

Rationale: The characteristic that distinguishes sulfonamides from other drugs used to treat bacterial infections is that sulfonamides are synthetic compounds, not derived from biologic substances. Choice A is incorrect because sulfonamides are bacteriostatic, not bactericidal. Choice C is incorrect because sulfonamides do not have antifungal and antiviral properties. Choice D is incorrect because sulfonamides act by inhibiting bacterial synthesis of folic acid, not increasing it.
