The nurse is caring for patient with a history of atrial fibrillation who is prescribed warfarin. Sometimes I forget my medication, so l double up doses when I remember " The patient's PT and INR are highly elevated. The nurse anticipates the transfusion of which blood product?
Packed Red Blood Cells (PRBC's)
Platelets
Cryoprecipitate
Fresh Frozen Plasma (FFP)
The Correct Answer is D
A) Packed Red Blood Cells (PRBCs):
Packed Red Blood Cells are typically transfused when there is anemia or significant blood loss leading to low hemoglobin levels. In the case of warfarin overdose or elevated PT/INR, the problem is related to coagulation and not red blood cell count.
B) Platelets:
Platelets are typically transfused when there is thrombocytopenia or a need to address platelet dysfunction (e.g., in patients with bleeding due to low platelet counts). However, the elevated PT and INR in this case are related to the coagulation cascade being inhibited by warfarin, not platelet deficiency.
C) Cryoprecipitate:
Cryoprecipitate is primarily used to replace clotting factors such as fibrinogen, factor VIII, and von Willebrand factor. It is typically transfused in patients with hemophilia or bleeding disorders related to low fibrinogen levels. However, in this case, the issue is related to warfarin-induced inhibition of clotting factors (specifically the vitamin K-dependent factors: II, VII, IX, and X), not a deficiency in fibrinogen or specific clotting factors addressed by cryoprecipitate.
D) Fresh Frozen Plasma (FFP):
Fresh Frozen Plasma (FFP) is the most appropriate choice for this patient. FFP contains all the coagulation factors, including the vitamin K-dependent factors that warfarin inhibits. When a patient on warfarin presents with elevated PT and INR (which indicates impaired clotting ability), FFP is used to replace the clotting factors and help reverse the effects of warfarin.

Correct Answer is B
Explanation
A) Treatment plan will need to be changed to achieve the desired effect:
The decrease in the carcinoembryonic antigen (CEA) levels from 50 ng/mL to 10 ng/mL suggests that the cancer is responding to the current treatment, not that the treatment plan needs to be changed. A drop in CEA levels typically indicates a positive response to treatment, such as chemotherapy, in reducing the number or size of cancer cells.
B) Cancer treatment is having the desired effect on killing cancer cells:
Carcinoembryonic antigen (CEA) is a tumor marker that is often elevated in individuals with certain cancers, particularly colorectal cancer. A decrease in CEA levels, as noted in this case (from 50 ng/mL to 10 ng/mL), usually signifies that the treatment is successfully targeting the cancer and reducing the tumor burden. This drop suggests that the chemotherapy is effectively killing cancer cells and reducing the size or activity of the tumor.
C) Client is at greater risk for tumor lysis syndrome:
Tumor lysis syndrome typically occurs when large numbers of cancer cells die rapidly, releasing their intracellular contents into the bloodstream, which can lead to metabolic disturbances like hyperkalemia, hyperphosphatemia, and renal failure. It is more common in aggressive hematologic cancers, such as leukemia or lymphoma, and typically presents with a rapid rise in tumor marker levels, not a decrease.
D) Cancer has increased size and metastatic sites:
An increase in tumor size or the development of metastatic sites would typically result in an increase in CEA levels, not a decrease. Since CEA levels have dropped, it is more likely that the cancer is shrinking or responding to the current treatment. This finding is more indicative of a positive response rather than disease progression.
Correct Answer is D
Explanation
A) Measure heart chamber pressures to assess for heart failure:
Measuring heart chamber pressures is an important diagnostic tool in assessing heart failure, but it is not the primary goal in the case of a STEMI (ST-Elevation Myocardial Infarction). In STEMI, the primary goal is to identify and treat the blockage in the coronary arteries that is causing the heart attack.
B) Determine cardiac output during the procedure:
Cardiac output is a useful measurement for assessing heart function, but it is not the main focus during the treatment of STEMI. While monitoring cardiac output may be part of the overall care, the urgent priority in STEMI management is to restore blood flow to the affected myocardial tissue as quickly as possible to minimize damage, not to measure cardiac output.
C) Evaluate the extent of the occlusion of the coronary arteries involved:
While evaluating the extent of coronary artery occlusion is part of the process during a cardiac catheterization, the immediate priority for a patient with STEMI is to treat the blockage, not just evaluate it. While the angiogram will reveal the blockage, the treatment goal is to restore perfusion to the affected area of the heart through procedures such as balloon angioplasty or stent placement.
D) Prevent extensive myocardial damage:
This is the correct answer. The main goal of treatment for STEMI is to prevent extensive myocardial damage. In a STEMI, the coronary artery is blocked, depriving the heart muscle of oxygen, which can cause significant damage or death of the myocardial tissue. The most effective way to limit the extent of damage is to restore blood flow as quickly as possible, often through emergent procedures like percutaneous coronary intervention (PCI) or fibrinolytic therapy.
