A nurse is contributing to the plan of care for a client who has thrombocytopenia due to chemotherapy. Which of the following interventions should the nurse include?

Choice A reason: This is a correct statement, because checking the heart rate each day can help monitor the function and effectiveness of the pacemaker, and detect any signs of malfunction, such as bradycardia, tachycardia, or irregular rhythm.

Choice B reason: This is an incorrect statement, because the client still needs to take the antihypertensive medications as prescribed, even with a pacemaker. The pacemaker regulates the heart rate, but does not control the blood pressure, which can be affected by other factors, such as stress, diet, or kidney function.

Choice C reason: This is an incorrect statement, because the client should avoid stretching the arms above the head for the first few weeks after the pacemaker insertion, as it can cause dislodgment or damage to the pacemaker leads. The client should limit the arm movements and activities until the incision site heals and the provider approves.

Choice D reason: This is an incorrect statement, because the client can stand in front of a microwave oven without any risk, as long as the oven is in good working condition and does not leak radiation. The modern microwave ovens and pacemakers are designed to prevent any interference or damage. However, the client should avoid close contact with other sources of electromagnetic fields, such as metal detectors, cell phones, or MRI machines.

Choice A reason: This is the correct intervention, because avoiding IM injections can prevent bleeding and hematoma formation in the client who has low platelet count and impaired clotting.

Choice B reason: This is an incorrect intervention, because obtaining a rectal temperature once per shift can cause trauma and bleeding in the rectal mucosa, which is highly vascularized and sensitive.

Choice C reason: This is an unnecessary intervention, because the client who has thrombocytopenia does not have an increased risk of infection, unless they also have neutropenia or immunosuppression. The client should be allowed to have visitors, as long as they follow the infection control precautions.

Choice D reason: This is an incorrect intervention, because encouraging daily flossing between teeth can cause gingival bleeding and ulceration in the client who has low platelet count and impaired clotting. The client should use a soft toothbrush and avoid dental floss.
