A client who weighs 176 pounds is prescribed enoxaparin sodium 1.5 mg/kg/day subcutaneously. The medication is available in a 120 mg/0.8 mL prefilled syringe.

How many mL should the nurse administer? (Enter numerical value only.)

Choice A rationale
Determining the presence of ST-elevations or non-ST-elevations on the electrocardiogram is an important step in diagnosing a myocardial infarction. However, this is typically performed by a healthcare provider or a trained technician, not a nurse.
Choice B rationale
While creating a calm and quiet environment can be beneficial for a client experiencing chest pain, it is not the immediate intervention that should be performed. The client’s symptoms suggest a possible cardiac event, which requires immediate medical intervention.
Choice C rationale
Verifying that troponin level assessments are scheduled every 3-6 hours for a series of three is important for diagnosing myocardial infarction. However, this is not the immediate intervention that should be performed. The client’s symptoms suggest a possible cardiac event, which requires immediate medical intervention.
Choice D rationale
Applying oxygen via nasal cannula and titrating to keep oxygen saturation above 93% is the correct intervention. This action helps to increase the oxygen supply to the myocardium, potentially decreasing the extent of myocardial damage and relieving chest pain.

Choice A rationale
Monitoring the patient’s blood pressure every 1 hour for 2 hours after paracentesis may not be sufficient. Paracentesis is a procedure to remove fluid that has accumulated in the abdominal cavity (a condition called ascites). This is a common problem in people with certain diseases, including liver and kidney disease. Changes in blood pressure can occur rapidly after this procedure, so more frequent monitoring is needed immediately after the procedure.
Choice B rationale
Monitoring the patient’s blood pressure every 5 minutes for one hour after paracentesis may be too frequent and could cause unnecessary stress for the patient. It is important to balance the need for monitoring with the patient’s comfort and well-being.
Choice C rationale
Monitoring the patient’s blood pressure every 15 minutes for one hour, then every 1 hour for 2 hours after paracentesis is a good schedule. This allows for close monitoring immediately after the procedure, when complications are most likely to occur. It then allows for continued monitoring as the patient stabilizes.
Choice D rationale
Monitoring the patient’s blood pressure every 5 minutes for 30 minutes, then every 4 hours thereafter may not provide enough monitoring in the immediate post-procedure period. While it is important to continue monitoring, the first few hours after the procedure are a critical time when complications are most likely to occur.
