Nursing Elites

1. A client with end-stage renal disease (ESRD) is receiving hemodialysis. Which laboratory value should the nurse monitor closely?

• A. Serum calcium level of 9 mg/dl
• B. Serum potassium level of 4.5 mEq/L
• C. Serum creatinine level of 2.0 mg/dl
• D. Serum sodium level of 138 mEq/L

Correct answer: C

Rationale: The correct answer is C: Serum creatinine level of 2.0 mg/dl. In a client with ESRD receiving hemodialysis, serum creatinine should be closely monitored. Elevated creatinine levels indicate impaired kidney function. Monitoring serum calcium levels (Choice A), serum potassium levels (Choice B), and serum sodium levels (Choice D) is also important in clients with ESRD, but the most crucial indicator of kidney function in this case is serum creatinine.

2. A client with a history of myocardial infarction is experiencing chest pain. Which intervention should the nurse implement first?

• A. Administer oxygen therapy as prescribed.
• B. Administer aspirin as prescribed.
• C. Administer nitroglycerin sublingually as prescribed.
• D. Obtain an electrocardiogram (ECG).

Correct answer: A

Rationale: Administering oxygen therapy is the initial priority in managing chest pain in a client with a history of myocardial infarction. Oxygen therapy helps improve oxygenation, which is crucial in reducing myocardial damage. While administering aspirin and nitroglycerin are essential interventions in the treatment of myocardial infarction, oxygen therapy takes precedence because it addresses the immediate need for oxygen supply to the heart muscle. Obtaining an ECG is important but can be done after ensuring adequate oxygenation.

3. An elderly female client with osteoarthritis reports increasing pain and stiffness in her right knee and asks how to reduce these symptoms. In responding to the client, the nurse recognizes what pathology as the cause of her symptoms?

• A. Destruction of joint cartilage.
• B. Inflammation of synovial membrane.
• C. Formation of bone spurs.
• D. Reduction of joint space.

Correct answer: A

Rationale: Corrected Rationale: Osteoarthritis typically involves the destruction of joint cartilage, leading to pain and stiffness. This destruction of joint cartilage results in bone rubbing against bone, causing pain and reduced mobility. Choices B, C, and D are incorrect. Inflammation of the synovial membrane (choice B) is more commonly associated with rheumatoid arthritis. Formation of bone spurs (choice C) and reduction of joint space (choice D) are manifestations that can occur as a result of osteoarthritis but are not the primary pathology responsible for the symptoms of pain and stiffness.

4. The nurse is caring for a client with chronic kidney disease (CKD). Which laboratory value should be reported to the healthcare provider immediately?

• A. Serum creatinine of 2.0 mg/dl
• B. Hemoglobin of 10 g/dl
• C. Potassium of 6.5 mEq/L
• D. Blood glucose of 150 mg/dl

Correct answer: C

Rationale: The correct answer is C. A potassium level of 6.5 mEq/L is dangerously high, a condition known as hyperkalemia, and requires immediate intervention to prevent cardiac complications. Hyperkalemia can lead to life-threatening arrhythmias, making it crucial to notify the healthcare provider promptly. Choices A, B, and D do not indicate immediate life-threatening conditions. Elevated serum creatinine levels are expected in CKD, a hemoglobin level of 10 g/dl is within a reasonable range, and a blood glucose level of 150 mg/dl is not acutely concerning in this context.

5. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.
