The nurse is caring for a client with heart failure.
Which of these prescribed medications places the client at risk for cardiogenic shock?

Choice A rationale
Mixing the dextrose in a 50 mL piggyback for a total volume of 100 mL is not the best method for administering the medication. This would dilute the dextrose, potentially reducing its effectiveness.
Choice B rationale
Diluting the dextrose in one liter of 0.9% normal saline solution is not the best method for administering the medication. This would significantly dilute the dextrose, potentially reducing its effectiveness.
Choice C rationale
Asking the pharmacist to add the dextrose to a total parenteral nutrition (TPN) solution is not the best method for administering the medication. This would not provide the immediate glucose boost needed to counteract insulin shock.
Choice D rationale

Pushing the undiluted dextrose slowly through the currently infusing IV is the best method for administering the medication. This allows for rapid administration of a concentrated glucose solution, which is necessary to quickly raise blood glucose levels in a patient experiencing insulin shock.

Choice A rationale
The most crucial intervention for a nurse to include in the care plan of a client with a deep vein thrombosis (DVT) in the left leg who is on a heparin protocol is to monitor for bleeding side effects related to heparin therapy. Heparin is an anticoagulant medication that prevents the formation of blood clots. While it is an effective treatment for DVT, it can also increase the risk of bleeding. Therefore, it is essential for the nurse to closely monitor the client for any signs of bleeding, such as unusual bruising, blood in urine or stool, or bleeding gums.
Choice B rationale
While promoting movement can help prevent a pulmonary embolism (a potential complication of DVT), it is not the most crucial intervention when a client is on a heparin protocol. Excessive movement can potentially dislodge the clot, leading to a pulmonary embolism. Therefore, while movement is important, it should be done under the guidance of a healthcare professional.
Choice C rationale
Checking blood pressure and heart rate at least every 4 hours is a standard nursing intervention for many clients, not just those with DVT. While it is important to monitor these vital signs, it is not the most crucial intervention for a client with DVT on a heparin protocol.
Choice D rationale

Measuring the circumference of each calf can help assess for leg edema, which can be a sign of DVT. However, this is not the most crucial intervention for a client on a heparin protocol. The priority is to monitor for bleeding side effects related to the heparin therapy.
