A nurse is caring for a school-age child who is 2 hr postoperative following a cardiac catheterization.

The nurse observes blood on the child’s dressing.

Choice A option

Fibrinogen level: Fibrinogen is a protein involved in the blood clotting process, but in this case, it is not appropriate because is not the primary laboratory test used to monitor warfarin therapy. Monitoring fibrinogen levels is more relevant in assessing bleeding disorders or certain medical conditions.

Choice B option

PTT (Partial Thromboplastin Time): PTT is another laboratory test used to evaluate blood clotting function, particularly the intrinsic pathway of the clotting cascade. PTT is not routinely used to monitor warfarin therapy; it is more commonly used to monitor other anticoagulant medications like heparin.

Choice C option

The nurse should plan to report the client's INR (International Normalized Ratio) to obtain a prescription for the client's daily warfarin. INR is a critical laboratory test used to monitor the effectiveness and safety of warfarin therapy.

Warfarin is an anticoagulant medication commonly prescribed to prevent and treat blood clots. It works by interfering with the body's ability to use vitamin K to form blood clots. Monitoring the INR is essential because it indicates how long it takes for the blood to clot, and it helps determine if the client's warfarin dosage needs adjustment to achieve the desired level of anticoagulation.

Choice D option

Platelet count: Platelet count is essential to assess the number of platelets in the blood, which are crucial for normal clotting. However, platelet count monitoring is not the primary focus when prescribing warfarin. It is typically used to evaluate thrombocytopenia (low platelet count) or other conditions affecting platelet function.

Choice A reason:

"You might experience altered taste sensations" is the correct statement. When providing teaching to a client about to undergo external radiation therapy for cancer, the nurse should include information about potential side effects and what to expect during the treatment. One common side effect of radiation therapy, especially when the treatment is focused on or near the head and neck region, is altered taste sensations. Radiation can affect the taste buds and lead to changes in how foods taste.

Choice B reason:

"Use rubbing alcohol to remove the ink markings. “The statement is incorrect. The ink markings made on the client's skin are used as reference points for the radiation therapy treatment. It is essential not to remove these markings, as they are crucial for accurate positioning during each treatment session. The nurse should instruct the client not to tamper with the markings, and the radiation therapy team will remove them when they are no longer needed.

Choice C reason:

"Wear a binder over the radiation site." The statement is incorrect. Wearing a binder over the radiation site is not a standard practice during external radiation therapy. The client should be instructed to follow the specific guidelines provided by the radiation therapy team regarding clothing and positioning during treatments. The use of binders or other tight clothing over the treatment area may not be recommended, as it can cause discomfort or interfere with the delivery of radiation.

Choice D reason

"Wash your skin thoroughly with a washcloth after each treatment." Is incorrect statement. During radiation therapy, the skin in the treatment area can become sensitive. It is essential for the client to follow the specific instructions provided by the radiation therapy team regarding skin care. Generally, the client should avoid using harsh soaps or scrubbing the skin vigorously. Instead, they should gently cleanse the area with a mild soap or as directed by their healthcare providers.
