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

Heparin is an anticoagulant medication that prevents the formation of blood clots. One of the most common and serious side effects of heparin therapy is bleeding. Therefore, it is crucial for the nurse to observe for signs of bleeding, such as bruising, petechiae, hematomas, black tarry stools, hematuria, and changes in mental status. Regular laboratory monitoring of the client’s coagulation status, specifically the activated partial thromboplastin time (aPTT), is also necessary to ensure therapeutic levels of heparin without causing excessive bleeding.

Choice B rationale

While mobilization can help prevent the formation of new clots, it is not the most important intervention for a client who is already on a heparin protocol for DVT. Mobilization can potentially dislodge the existing clot, leading to a life-threatening pulmonary embolism.

Choice C rationale

Although it is important to monitor vital signs in all clients, assessing blood pressure and heart rate every 4 hours is not the most important intervention for a client on a heparin protocol.

Changes in blood pressure and heart rate are not specific to heparin therapy and do not provide direct information about the effectiveness or side effects of the medication.

Choice D rationale

Measuring each calf’s girth can help evaluate the progression of edema in the affected leg, but it is not the most important intervention for a client on a heparin protocol. While it can provide information about the local effects of the DVT, it does not address the systemic anticoagulation effects of heparin therapy.

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.
