A nurse is caring for a client who has a pulmonary embolism and has been on a heparin continuous infusion for 5 days. The provider prescribes warfarin PO without discontinuing the heparin. The client asks the nurse why both anticoagulants are necessary. Which of the following statements should the nurse make?
"Both heparin and warfarin work together to dissolve the clots."
"Warfarin takes several days to work, so the IV heparin will be used until the warfarin reaches a therapeutic level."
"The IV heparin increases the effects of the warfarin and decreases the length of your hospital stay."
"I will call the provider to get a prescription for discontinuing the IV heparin today."
The Correct Answer is B
Choice A reason: Heparin and warfarin do not work together to dissolve clots. Heparin acts quickly to prevent further clotting, while warfarin is used for long-term anticoagulation.
Choice B reason: Warfarin's onset of action is slow, requiring several days to reach therapeutic levels. During this time, heparin is used to provide immediate anticoagulation to prevent new clot formation or the growth of existing clots.
Choice C reason: IV heparin does not increase the effects of warfarin. They are used concurrently because of the delay in warfarin's onset of action.
Choice D reason: It is not appropriate to discontinue heparin immediately after starting warfarin due to the delay in warfarin reaching therapeutic levels. The overlap is necessary to ensure continuous anticoagulation.

Correct Answer is B
Explanation
Choice A: “I have a tight sensation in my lower leg when I forget to put my feet up.” This statement may indicate the presence of edema, which is common in cirrhosis due to hypoalbuminemia and sodium retention. However, it is not as immediately concerning as other symptoms because it can often be managed with diuretics and compression. It is important to monitor for worsening edema, as it can lead to increased discomfort and risk of skin breakdown.
Choice B: “I can’t button my pants anymore because my belly is so swollen.” This statement is concerning because it suggests the development of ascites, which is the accumulation of fluid in the peritoneal cavity, causing abdominal swelling. Ascites can lead to abdominal discomfort, difficulty breathing, and is a sign of advanced liver disease with significant portal hypertension. It requires medical evaluation and management, which may include paracentesis (removal of fluid), diuretics, and sodium restriction. Cirrhosis is a late stage of scarring (fibrosis) of the liver caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcoholism. Portal hypertension is an increase in the blood pressure within a system of veins called the portal venous system. Veins from the stomach, intestine, spleen, and pancreas merge into the portal vein, which then branches into smaller vessels and travels through the liver.
Choice C: “I’m very constipated and have been straining during bowel movements.” While constipation is uncomfortable and can indicate dietary issues or side effects from medication, it is not typically a direct complication of cirrhosis or portal hypertension. However, straining during bowel movements can increase the risk of bleeding from esophageal varices if they are present, so it is important to manage constipation to prevent potential complications.
Choice D: “When I sleep, I have to sit in a recliner so that I can breathe more easily.” This statement indicates orthopnea, which can be associated with ascites or pleural effusions (fluid in the lungs), both of which can occur in the setting of cirrhosis and portal hypertension. While this symptom is concerning and affects the client’s quality of life, it is generally less concerning than the development of ascites, as it can be managed with adjustments in sleeping position and medical management of the underlying fluid accumulation.
Correct Answer is ["B","C","D","E","F"]
Explanation
Choice A: Bradycardia Bradycardia, or a slower than normal heart rate, is not typically a direct symptom of flail chest. While traumatic injuries can lead to various cardiac responses, bradycardia is not commonly associated with the respiratory distress seen in flail chest. Flail chest is a serious condition that occurs when a segment of the rib cage breaks due to trauma and becomes detached from the rest of the chest wall. This can severely affect breathing and lead to other complications.
Choice B: Anxiety Anxiety is a common response in patients with flail chest due to the pain and difficulty in breathing associated with the condition. The stress of the injury and the body’s response to the trauma can lead to feelings of anxiety and panic.
Choice C: Dyspnea Dyspnea, or difficulty breathing, is one of the primary symptoms of flail chest. The instability of the chest wall and the paradoxical movement of the flail segment impair the normal mechanics of breathing, leading to shortness of breath.
Choice D: Unequal chest expansion Unequal chest expansion is a hallmark sign of flail chest. The affected area of the chest wall moves in the opposite direction to the rest of the chest during the respiratory cycle, which can be observed as an abnormal movement during inhalation and exhalation.
Choice E: Hypotension Hypotension, or low blood pressure, can occur in flail chest cases, especially if there is associated trauma such as bleeding or if the patient is in shock. The body’s response to the injury and the potential for compromised venous return due to the chest wall’s dysfunction can lead to hypotension.
Choice F: Paradoxical chest movement Paradoxical chest movement is a definitive sign of flail chest. It occurs when the broken section of the rib cage moves inward during inhalation and outward during exhalation, opposite to the normal chest movement. This is due to the loss of stability in the chest wall and is easily observable during a physical examination. Flail chest is a critical condition that requires immediate medical attention. The signs and symptoms associated with this condition include anxiety, dyspnea, unequal chest expansion, hypotension, and paradoxical chest movement. These symptoms reflect the underlying pathophysiology of the condition, which is the instability of the chest wall and the resulting impairment of normal respiratory function.
