Question 3 of 4
After assisting in a left lateral thoracentesis for a client with pleural effusion, the nurse monitors the client post-procedure. Which finding warrants immediate intervention?
Correct Answer: B
Rationale: Subcutaneous emphysema around the insertion site post-thoracentesis warrants immediate intervention. This indicates air has escaped into the subcutaneous tissue, potentially from a pneumothorax or procedural complication, which can progress to respiratory distress or tension pneumothorax. Pain on inhalation is expected, decreased breath sounds may reflect the effusion's residual effect, and 90% saturation, while low, is less urgent than emphysema's potential for rapid deterioration, requiring prompt reporting and possible chest tube placement.
Question 4 of 4
The HCP prescribes metoclopramide 7.5 mg/ml IM q3hr PRN vomiting for a client who receives chemotherapy. The nurse prepared the injection using a 2 ml prefilled syringe cartridge labeled, metoclopramide 5 mg/ml. How many ml should the nurse administer?
Correct Answer: B
Rationale: To administer 7.5 mg of metoclopramide from a 5 mg/ml syringe, the nurse calculates: Dose desired (7.5 mg) ÷ concentration (5 mg/ml) = 1.5 ml. This ensures the correct amount is given intramuscularly for vomiting control post-chemotherapy. 1 ml delivers 5 mg (too little), 2 ml gives 10 mg (too much), and 0.5 ml provides 2.5 mg (insufficient), making 1.5 ml the precise volume needed based on standard medication math.
