Which clinical manifestation should the nurse anticipate as an expected finding for a client diagnosed with deep vein thrombosis (DVT)?
A. Widespread edema of the affected extremity.
Deep vein thrombosis (DVT) is a condition characterized by the formation of a blood clot in a deep vein, usually in the leg. One of the most common symptoms of DVT is swelling of the affected extremity. This occurs because the blood clot obstructs the flow of blood, causing fluid to build up in the tissues.
B. Small area of redness of the affected extremity.
While redness can be a symptom of DVT, it is not typically confined to a small area. Instead, redness associated with DVT is usually more widespread and is often accompanied by other symptoms such as swelling and pain.
C. Cool, mottled affected extremity.
A cool, mottled extremity is not a typical symptom of DVT34. DVT usually causes the affected area to feel warmer than the surrounding areas due to inflammation caused by the blood clot.
D. Positive bilateral peripheral pulses.
The presence of bilateral peripheral pulses is not a specific finding for DVT34. In fact, the presence of strong peripheral pulses may suggest that blood flow is not significantly obstructed.

A nurse is educating a patient with diabetes mellitus about the chronic complications associated with the disease. What information should be included in the teaching?
A. Schedule and keep appointments for annual eye exams.
Diabetes mellitus can lead to several chronic complications, including retinopathy, which can cause blindness. Regular eye exams are crucial for early detection and treatment of diabetic retinopathy. Therefore, scheduling and keeping appointments for annual eye exams is an important part of managing diabetes.
B. Ensure adequate fluid intake to prevent kidney damage.
While adequate fluid intake is generally important for overall health, it is not specifically effective in preventing kidney damage in patients with diabetes mellitus. Kidney damage in diabetes, also known as diabetic nephropathy, is caused by high blood sugar levels over time, not by dehydration.
C. Cardiac enzymes will be checked every 6 months.
Regular checks of cardiac enzymes are not a standard part of diabetes management. Cardiac enzymes are typically checked in the context of suspected heart disease or a heart attack, not as a routine measure in diabetes care.
D. Podiatry exams are necessary every 3 months.
While regular foot care is important in diabetes to prevent complications such as foot ulcers and infections, podiatry exams every 3 months are not typically necessary unless the patient has a history of foot problems or a high risk of foot complications.

A patient diagnosed with deep vein thrombosis asks the nurse, “How does this blood thinner heparin work?” Which response is most accurate?
A. Heparin makes the blood less thick and easier to flow.
Heparin does not actually thin the blood or make it less thick. Instead, it works by increasing the activity of antithrombin, a protein that inhibits blood clotting. This prevents new clots from forming and existing clots from growing larger.
B. Heparin dissolves the clot and decreases the formation of platelets.
Heparin does not dissolve clots or decrease the formation of platelets. Its primary action is to increase the activity of antithrombin, which in turn inactivates thrombin and factor Xa, two key players in the blood clotting process.
C. Heparin does not thin the blood; it prevents new clots from forming.
This statement is accurate. Heparin does not thin the blood; instead, it prevents new clots from forming and existing clots from growing larger. It does this by increasing the activity of antithrombin, which in turn inactivates thrombin and factor Xa.
D. Heparin decreases the number of platelets so the blood flows more easily.
Heparin does not decrease the number of platelets or make the blood flow more easily. Its primary action is to increase the activity of antithrombin, which in turn inactivates thrombin and factor Xa.

The nurse identifies the problem of Fluid Volume Excess for a patient. Which assessment finding validates this problem?
A. Urine specific gravity 1.012.
Fluid Volume Excess (FVE), or hypervolemia, refers to an isotonic expansion of the ECF due to an increase in total body sodium content and an increase in total body water. This fluid overload usually occurs from compromised regulatory mechanisms for sodium and water as seen commonly in heart failure (CHF), kidney failure, and liver failure. The key signs of hypervolemia include weight gain and swelling. One of the defining characteristics of FVE is an increase in urine specific gravity. Therefore, a urine specific gravity of 1.012 can validate the problem of Fluid Volume Excess for a patient.
B. +4 Pedal pulses.
+4 Pedal pulses indicate a very bounding and strong pulse, which is not directly related to Fluid Volume Excess. While it might be observed in some cases due to increased blood volume and pressure, it is not a specific or primary indicator of this condition.
C. Respiratory rate 20/minute.
A respiratory rate of 20/minute is within the normal range for an adult (12-20 breaths per minute) and does not specifically indicate Fluid Volume Excess. While respiratory changes can occur with severe or prolonged Fluid Volume Excess, a normal respiratory rate does not validate this diagnosis.
D. Potassium level 3.8 mEq/L.
A potassium level of 3.8 mEq/L is within the normal range (3.5-5.0 mEq/L) and does not specifically indicate Fluid Volume Excess. While electrolyte imbalances can occur with Fluid Volume Excess, a normal potassium level does not validate this diagnosis.
