Three days ago, a patient had cardiac surgery to bypass three occlusions of his coronary arteries. Veins for the bypass were harvested from his right leg. He informs the nurse that his leg is warm and tender in his right calf.
 
  The nurse notes a 3-cm periwound erythema and swelling at the distal end of the incision. Staples are intact along the incision, and there is no drainage. Vital signs are stable. The nurse would suspect that the patient has what kind of complication?
  a. Deep vein thrombosis
  b. Dehiscence of the wound
  c. Internal bleeding
  d. Infection at the incisional site

Question 2

The nurse is teaching a pregnant woman about the increased oxygen demand that develops during pregnancy. The nurse knows the patient comprehends the teaching when she makes the following statement:
 
  a. I may need to drink more fluids to make more oxygen.
  b. I may need to take an iron supplement so that I am not anemic.
  c. I will need a multivitamin supplement for several months.
  d. I will need to eat more fruits and vegetables.

Answer to Question 1

A
Deep vein thrombosis (DVT) is a clot in the veins that are deep under the muscles of the leg. DVT can occur after surgery, after lengthy bedrest, or after trauma. Symptoms include pain, warmth, redness, and swelling of the leg. Dorsiflexion of the foot (pulling toes forward) and Pratt's sign (squeezing calf to trigger pain) have not been found to be reliable in diagnosing DVT. Dehiscence is the rupture of a suture line, whereas evisceration is the protrusion of internal organs through the rupture. Internal bleeding is a wound-healing complication associated with hematoma formation, pain, hypotension, and tachycardia. Infection is a complication of wound healing that causes warmth, pain, inflammation of the affected area, and changes in vital signs (i.e., elevated pulse and temperature).

Answer to Question 2

B
During pregnancy, oxygen demand increases dramatically. To compensate, the mother's blood volume increases by 30. The woman requires additional iron to produce this blood as well as to meet fetal requirements. Failure to meet these iron demands can result in maternal anemia, reducing tissue oxygenation of the mother.
