1. A client with chronic kidney disease (CKD) is scheduled for a hemodialysis session. Which laboratory value should the nurse report to the healthcare provider before the procedure?
- A. Serum potassium of 5.5 mEq/L
- B. Blood urea nitrogen (BUN) of 40 mg/dl
- C. Serum potassium of 6.0 mEq/L
- D. Serum creatinine of 2.5 mg/dl
Correct answer: C
Rationale: A serum potassium level of 6.0 mEq/L is dangerously high for a client with chronic kidney disease (CKD) scheduled for hemodialysis. High potassium levels can lead to cardiac complications such as arrhythmias. Therefore, it is crucial to report this value to the healthcare provider before the procedure to prevent any potential serious complications. Choices A, B, and D are not as critical in the context of preparing for a hemodialysis session. Serum potassium levels above 6.0 mEq/L require immediate attention to ensure patient safety.
2. A client with a history of myocardial infarction is admitted with chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?
- A. Electrocardiogram (ECG)
- B. Chest X-ray
- C. Arterial blood gases (ABGs)
- D. Echocardiogram
Correct answer: A
Rationale: The correct answer is A: Electrocardiogram (ECG). An electrocardiogram should be performed first to assess for cardiac ischemia in a client with a history of myocardial infarction and chest pain. This test provides immediate information about the heart's electrical activity. Choice B, Chest X-ray, is used to visualize the structures of the chest, including the heart and lungs, but it does not directly assess for cardiac ischemia. Choice C, Arterial blood gases (ABGs), measures the oxygen and carbon dioxide levels in the blood and assesses acid-base balance, which is not the primary concern in this scenario. Choice D, Echocardiogram, is an ultrasound of the heart that provides information about the heart's structure and function, but it is not the initial diagnostic test for assessing cardiac ischemia in this situation.
3. The nurse is assessing the thorax and lungs of a client who is experiencing respiratory difficulty. Which finding is most indicative of respiratory distress?
- A. Contractions of the sternocleidomastoid muscle.
- B. Respiratory rate of 20 breaths/min
- C. Downward movement of diaphragm with inspiration
- D. A pulse oximetry reading of SpO2 95%
Correct answer: A
Rationale: The correct answer is A: Contractions of the sternocleidomastoid muscle. Contractions of the sternocleidomastoid muscle suggest that the client is using accessory muscles to breathe, which is a clear sign of respiratory distress. This finding indicates that the client is working harder to breathe, typically seen in conditions like asthma, COPD, or respiratory failure. Choices B, C, and D are not the most indicative of respiratory distress. A respiratory rate of 20 breaths/min falls within the normal range. Downward movement of the diaphragm with inspiration is a normal finding indicating effective diaphragmatic breathing. A pulse oximetry reading of SpO2 95% is within the normal range and does not necessarily indicate respiratory distress.
4. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be monitored closely?
- A. Serum potassium
- B. Hemoglobin
- C. Serum sodium
- D. White blood cell count
Correct answer: A
Rationale: The correct answer is A: Serum potassium. When a client with chronic kidney disease is undergoing erythropoietin therapy, monitoring serum potassium levels is crucial. Erythropoietin can stimulate red blood cell production, which may lead to an increase in potassium levels, predisposing the client to hyperkalemia. Monitoring serum potassium levels helps in early detection of hyperkalemia and appropriate intervention. Choices B, C, and D are incorrect because although hemoglobin, serum sodium, and white blood cell count are important parameters to monitor in various clinical conditions, they are not specifically associated with erythropoietin therapy in chronic kidney disease.
5. The charge nurse of the critical care unit informed at the beginning of the shift that a less than optimal number of registered nurses would be working that shift. In planning assignments, which client should receive the most care hours by a registered nurse?
- A. A 34-year-old admitted today after an emergency appendectomy who has a peripheral intravenous catheter and a Foley catheter.
- B. A 48-year-old marathon runner with a central venous catheter experiencing nausea and vomiting due to electrolyte disturbance following a race.
- C. A 63-year-old chain smoker with chronic bronchitis receiving oxygen via nasal cannula and a saline-locked peripheral intravenous catheter.
- D. An 82-year-old client with Alzheimer's disease and a newly fractured femur with a Foley catheter and soft wrist restraints applied.
Correct answer: D
Rationale: The 82-year-old client with Alzheimer's disease and a newly fractured femur should receive the most care hours by a registered nurse because they are at the highest risk for injury and complications. The client's age, diagnosis of Alzheimer's disease, and the presence of a newly fractured femur along with the Foley catheter and wrist restraints indicate a need for close monitoring and care. Choice A is less critical as the client is stable post-appendectomy. Choice B, though experiencing symptoms, is not at the same level of risk as the client in Choice D. Choice C, while requiring oxygen support, does not have the same level of acuity and complexity as the client in Choice D.
