A nurse is reporting a client's laboratory tests to the provider to obtain a prescription for the client's daily warfarin. Which of the following laboratory tests should the nurse plan to report to obtain the prescription for the warfarin?
INR
Fibrinogen level
aPTT
Platelet count
The Correct Answer is A
A. Correct. The International Normalized Ratio (INR) is used to monitor the effectiveness of warfarin therapy, which is commonly prescribed to prevent blood clotting. The INR provides information about the client's prothrombin time (PT) in relation to a standardized value.
B. Fibrinogen level measures clotting potential but is not directly related to warfarin therapy monitoring.
C. Activated Partial Thromboplastin Time (aPTT) is used to monitor other anticoagulants like heparin, not warfarin.
D. Platelet count measures the number of platelets in the blood and is not specifically related to warfarin therapy monitoring.

Explanation
A. "Try using an abdominal support belt." - An abdominal support belt is recommended to provide support to the growing abdomen and can help alleviate backaches that are common during pregnancy.
B. "Take hot showers to help relieve itching." - This statement is incorrect. Hot showers can actually worsen itching and dry out the skin. Lukewarm showers are recommended instead.
C. "Wear loose-fitting clothing." - This statement is correct. Loose-fitting clothing can provide comfort and reduce irritation, especially in areas experiencing itching.
D. "Wear flat or low-heeled shoes." - This statement is correct. Flat or low-heeled shoes provide better support and stability during pregnancy, reducing the risk of falls.
E. "You can douche twice weekly." - This statement is incorrect. Douching is not recommended during pregnancy as it can disrupt the natural balance of vaginal flora and increase the risk of infections.
F. "Eat two large meals a day." - This statement is incorrect. Eating large meals can lead to discomfort and heartburn. It is better to eat frequent smaller meals throughout the day during pregnancy.
G. "You should avoid fried foods." - This statement is correct. Fried foods can exacerbate heartburn and should be avoided to reduce discomfort.
Correct Answer is B
Explanation
Choice A rationale:
Varicella vaccine is typically administered to children at the age of 1 year, not at 2 months. The first dose of varicella vaccine is usually given at 12-15 months of age, with a second dose recommended at 4-6 years of age.
Choice B rationale:
Rotavirus vaccine is recommended to be administered to infants at the age of 2 months. It is an oral vaccine that protects against rotavirus infections, a common cause of severe diarrhea and dehydration in infants and young children.
Choice C rationale:
Influenza vaccine is not typically administered to infants at 2 months of age. Influenza vaccination is recommended annually for children older than 6 months.
Choice D rationale:
Hepatitis A vaccine is not routinely given at 2 months of age. Hepatitis A vaccination is typically recommended starting at 1 year of age, with a second dose administered 6-18 months later.
