Nursing Elites

1. A client with chronic kidney disease (CKD) is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?

• A. Serum potassium
• B. Hemoglobin
• C. White blood cell count
• D. Serum creatinine

Correct answer: A

Rationale: The correct answer is A: Serum potassium. When a client with chronic kidney disease is receiving erythropoietin therapy, monitoring serum potassium closely is essential. Erythropoietin therapy can lead to increased red blood cell production, which may cause potassium levels to rise, potentially resulting in hyperkalemia. Monitoring potassium levels helps prevent complications associated with hyperkalemia. Choices B, C, and D are incorrect because they are not directly impacted by erythropoietin therapy in the context of CKD.

2. A healthcare provider is assessing a client with a history of hypertension who is currently taking a diuretic. Which assessment finding is most important to report to the healthcare provider?

• A. Potassium level of 3.2 mEq/L
• B. Blood pressure of 148/90 mmHg
• C. Pulse rate of 62 beats per minute
• D. Blood glucose level of 130 mg/dl

Correct answer: A

Rationale: A potassium level of 3.2 mEq/L is low and places the client at risk for cardiac arrhythmias, requiring immediate intervention. Hypokalemia can result from diuretic use and can lead to serious complications such as irregular heart rhythms. Monitoring and correcting potassium levels are crucial in preventing adverse cardiac events. The other options, though important, do not pose an immediate life-threatening risk compared to the low potassium level.

3. The healthcare provider prescribes ceftazidime (Fortaz) 35 mg every 8 hours IM for an infant. The 500 mg vial is labeled with the instruction to add 5.3 ml diluent to provide a concentration of 100 mg/ml. How many ml should the nurse administer for each dose?

• A. 0.35 ml
• B. 0.40 ml
• C. 0.50 ml
• D. 0.45 ml

Correct answer: B

Rationale: To calculate the volume to be administered for 35 mg of ceftazidime, divide the prescribed dose by the concentration: 35 mg / 100 mg/ml = 0.35 ml. Rounding off, the nurse should administer 0.4 ml for each dose. Choice A is incorrect as it doesn't consider rounding off. Choice C is incorrect because it's not the correct calculation. Choice D is incorrect as it doesn't reflect the accurate volume needed.

4. The nurse is caring for a client with a history of myocardial infarction who is experiencing chest pain. Which intervention should the nurse implement first?

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

Correct answer: A

Rationale: Administering oxygen therapy is the priority intervention in managing chest pain in a client with a history of myocardial infarction. Oxygen helps improve oxygenation to the heart muscle, which is crucial in reducing further damage. Obtaining an electrocardiogram (ECG) is important to assess for changes indicative of myocardial infarction, but providing oxygen takes precedence as it directly addresses the physiological need for oxygen. Administering nitroglycerin and aspirin are important interventions but are typically implemented after oxygen therapy to address vasodilation and antiplatelet effects, respectively.

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.
