1. A client is receiving a secondary infusion of erythromycin 1 gram in 100 mL dextrose 5% in water (D5W) to be infused in 45 minutes. How many mL/hour should the nurse program the infusion pump?
- A. 100 mL/hour.
- B. 125 mL/hour.
- C. 133 mL/hour.
- D. 150 mL/hour.
Correct answer: C
Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.
2. A client with hyperkalemia is being treated in the emergency department. Which medication should the nurse prepare to administer?
- A. Potassium chloride
- B. Calcium gluconate
- C. Magnesium sulfate
- D. Sodium bicarbonate
Correct answer: B
Rationale: The correct answer is B, Calcium gluconate. In hyperkalemia, where potassium levels are elevated, calcium gluconate is administered to stabilize the myocardial cell membrane and protect the heart from potential arrhythmias. Potassium chloride (choice A) would worsen the condition by further increasing potassium levels. Magnesium sulfate (choice C) is not the primary treatment for hyperkalemia. Sodium bicarbonate (choice D) is used in metabolic acidosis, not specifically for hyperkalemia.
3. A young female client with 7 children is having frequent morning headaches, dizziness, and blurred vision. Her BP is 168/104. The client reports that her husband recently lost his job and she is not sleeping well. After administering a STAT dose of an antihypertensive IV med, which intervention is most important for the nurse to implement?
- A. Measure urine output hourly to assess for renal perfusion
- B. Request a prescription for pain medication
- C. Use an automated BP machine to monitor for hypotension
- D. Provide a quiet environment with low lighting
Correct answer: C
Rationale: Using an automated BP machine is crucial to continuously monitor for hypotension after administering an antihypertensive medication. This is essential to prevent a rapid drop in blood pressure that could lead to complications. Measuring urine output hourly to assess for renal perfusion is important but not the most immediate concern in this situation. Requesting pain medication is not relevant to the primary issue of managing blood pressure. Providing a quiet environment with low lighting may be beneficial for the client's overall well-being but is not as critical as monitoring for potential hypotension.
4. Which dietary modification is most appropriate for a client with nephrotic syndrome?
- A. High protein, low sodium
- B. Low protein, high sodium
- C. High protein, high potassium
- D. Low protein, low sodium
Correct answer: D
Rationale: The most appropriate dietary modification for a client with nephrotic syndrome is a low protein, low sodium diet. This diet helps reduce the workload on the kidneys and manage edema, which are common issues in nephrotic syndrome. Choice A, high protein, low sodium, is not recommended because excessive protein intake can further strain the kidneys. Choice B, low protein, high sodium, is inappropriate as high sodium can worsen fluid retention and hypertension. Choice C, high protein, high potassium, is not ideal as high potassium levels can be problematic for individuals with kidney issues.
5. A client who had surgery yesterday is becoming increasingly anxious. The client’s respiratory rate has increased to 38 breaths/minute. The client has a nasogastric tube to low intermittent suction with 500 ml of yellow-green drainage over the last four hours. The client's arterial blood gases (ABGs) indicate a decreased CO2 and an increased serum pH. Which serum laboratory value should the nurse monitor first?
- A. Electrolytes.
- B. Creatinine.
- C. Blood urea nitrogen.
- D. Glucose.
Correct answer: A
Rationale: The correct answer is A, Electrolytes. In this scenario, the client is at risk for metabolic alkalosis due to the loss of gastric secretions through the nasogastric tube. Monitoring electrolytes is crucial to assess the levels of sodium, potassium, chloride, and bicarbonate, which are important in maintaining the acid-base balance of the body. Changes in these electrolyte levels can provide valuable information about the client's fluid status and acid-base balance. Creatinine, blood urea nitrogen, and glucose levels are important parameters to monitor in different situations but are not the priority in this case of potential metabolic alkalosis.
