A nurse is caring for a client who has cirrhosis and a prothrombin time of 30 seconds. Which of the following medications should the nurse plan to administer?
Warfarin
Vitamin K
Heparin
Ferrous sulfate
The Correct Answer is B
A. Warfarin:
Warfarin is an anticoagulant that works by inhibiting the synthesis of certain clotting factors, including factors II, VII, IX, and X. While it is used to prevent thromboembolic events, in a client with cirrhosis and an elevated PT, the priority is addressing the coagulation factor deficiency rather than adding an anticoagulant.
B. Vitamin K:
Vitamin K is the antidote for warfarin, and it helps in the synthesis of clotting factors. In cirrhosis, there can be impaired synthesis of clotting factors due to liver dysfunction. Administering vitamin K can aid in correcting coagulation abnormalities.
C. Heparin:
Heparin is another anticoagulant, but it does not reverse the effects of warfarin. It works by a different mechanism and is typically used in acute settings, such as deep vein thrombosis or pulmonary embolism. It is not the primary intervention for an elevated PT in cirrhosis.
D. Ferrous sulfate:
Ferrous sulfate is an iron supplement and is not indicated for the correction of an elevated PT. Iron supplements are typically used to address iron deficiency anemia.

Correct Answer is B
Explanation
A. Blood glucose level below 40 mg/dL is not typical in diabetic ketoacidosis. DKA is characterized by hyperglycemia, and blood glucose levels are usually significantly elevated.
B. Acetone odor to breath is a classic sign of diabetic ketoacidosis. The presence of ketones, including acetone, can result in a fruity or sweet odor to the breath. This is often referred to as "ketone breath."
C. Malignant hypertension is not a typical manifestation of diabetic ketoacidosis. DKA is more commonly associated with dehydration, electrolyte imbalances, and metabolic acidosis.
D. Cheyne-Stokes breathing is not a characteristic respiratory pattern seen in diabetic ketoacidosis. Respiratory changes in DKA are more likely to involve rapid and deep breathing (Kussmaul respirations) as the body attempts to compensate for metabolic acidosis.
Correct Answer is C
Explanation
A. "I'll wear sandals in warm weather":
While wearing sandals in warm weather can be comfortable, it may not provide adequate protection for the feet, especially for individuals with diabetes. Closed, protective shoes are generally recommended to prevent injuries.
B. "I'll put lotion between my toes after drying my feet":
Applying lotion between the toes can create a moist environment, which may increase the risk of fungal infections. It is generally advisable to keep the skin between the toes dry to prevent infections.
C. "I'll check my feet every day for sores and bruises":
This statement is correct. Regular foot checks are crucial for individuals with diabetes to identify any signs of sores, bruises, or other abnormalities early. Early detection and prompt treatment can help prevent complications.
D. "I’ll soak my feet in cool water every night before I go to bed":
Soaking the feet in cool water is generally not recommended, as it can lead to maceration of the skin and increase the risk of fungal infections. Daily inspection and proper hygiene are more important aspects of foot care.
