A nurse is preparing to administer warfarin to a client who has chronic atrial fibrillation. Which of the following laboratory values should the nurse monitor prior to administering the medication?
LDL
INR
BUN
Hct
The Correct Answer is B
Choice A Reason:
LDL (Low-Density Lipoprotein) is incorrect. This is a type of cholesterol and is not specifically monitored in relation to warfarin therapy.
Choice B Reason:
INR (International Normalized Ratio) is correct. Warfarin is an anticoagulant medication, and its dosage needs to be adjusted based on the INR levels. INR monitoring helps assess the clotting tendency of the blood and ensures that the dosage of warfarin is within the therapeutic range to prevent blood clots without causing excessive bleeding.
Choice C Reason:
BUN (Blood Urea Nitrogen) is incorrect. This value is primarily used to assess kidney function and is not directly related to monitoring warfarin therapy.
Choice D Reason:
Hct (Hematocrit) is incorrect. This measures the percentage of red blood cells in the blood and is not directly related to monitoring warfarin therapy for atrial fibrillation.

Correct Answer is ["1000"]
Explanation
To lose 0.9 kg (2 lb.) of body fat per week, we can calculate the daily caloric deficit required.
1 lb. of body fat = 3,500 calories
So, for 2 lb. of body fat = 2 * 3,500 = 7,000 calories per week
To lose 0.9 kg (2 lb.) of body fat per week:
7,000 calories ÷ 7 days = 1,000 calories per day
Therefore, the client should reduce their daily caloric intake by approximately 1,000 calories per day to achieve a weight loss of 0.9 kg (2 lb.) of body fat per week.
Correct Answer is A
Explanation
Choice A Reason:
Elevate the head of the client's bed for 1 hr. after the feeding is appropriate. This action helps minimize the risk of aspiration. Elevating the head of the bed (typically at least 30 to 45 degrees) can reduce the chance of reflux and aspiration of the feeding solution into the lungs. This position should ideally be maintained for about 1 hour after the feeding to aid digestion and reduce the risk of complications.
Choice B Reason:
Administering the feeding solution at a cold temperature is inappropriate. Feeding solutions are generally administered at room temperature or slightly warmed to prevent discomfort and minimize the risk of altering the client's core body temperature. Cold temperatures can cause discomfort or cramping and might affect the absorption of the nutrients. Therefore, administering the feeding solution at a cold temperature is not recommended.
Choice C Reason:
Rotating the jejunostomy tube once per day is inappropriate. Rotating the jejunostomy tube is not typically part of routine care. Tube rotation can cause discomfort, irritation, and potential injury to the gastrointestinal tract. Tubes should be secured properly to prevent movement but not rotated unless specifically instructed by a healthcare provider for a particular reason, such as checking for proper tube placement.
Choice D Reason:
Flushing the tube with 90 ml of sterile water before and after the feeding is inappropriate.
Flushing the tube with sterile water before and after the feeding helps ensure the patency of the tube and prevents clogging. It's a standard procedure to clear the tube and maintain its function
