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 D
Explanation
A. Avoiding eating at fast food restaurants is not a specific preventive measure for hepatitis A transmission. The primary mode of transmission for hepatitis A is through the fecal-oral route, often due to contaminated food or water.
B. Avoiding serving raw foods is a reasonable precaution as raw or undercooked shellfish and contaminated fruits and vegetables can be a source of hepatitis A transmission. However, practicing effective hand hygiene is a more general and fundamental preventive measure.
C. Wearing barrier protection during vaginal intercourse is not directly related to the prevention of hepatitis A. Hepatitis A is primarily transmitted through the fecal-oral route, and sexual transmission is not a common mode for this virus.
D. Practicing effective hand hygiene is a key strategy for preventing the transmission of hepatitis A. Proper handwashing with soap and water, especially after using the bathroom and before handling food, can help reduce the risk of contamination and transmission of the virus.
Correct Answer is C
Explanation
A. Administer medications:
While nasogastric tubes can be used to administer medications, this is not the primary rationale for their use in pyloric obstruction. The primary goal is often decompression.
B. Supply nutrients via tube feedings:
Providing nutrients via tube feedings is not the primary purpose in the context of a pyloric obstruction. Decompression is more relevant in this scenario.
C. Decompress the stomach:
Decompressing the stomach is a common use of nasogastric tubes in the context of pyloric obstruction. The tube helps to remove excess air and gastric contents, relieving pressure in the stomach.
D. Determine the pH of the gastric secretions:
While determining the pH of gastric secretions is a possible use, it is not the primary rationale for nasogastric tube placement in pyloric obstruction. The primary goal is often to relieve obstruction and decompress the stomach.
