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

Answer and Explanation

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, the client needs to create a weekly caloric deficit of 7000 calories (3500 x 2).

This means that he needs to reduce his daily caloric intake by 1000 calories (7000 / 7).

The nurse should instruct the client to calculate his current daily caloric intake and then subtract 1000 calories from that amount. The nurse should also advise the client to eat a balanced diet and exercise regularly to achieve his weight loss goal.

A. Instruct the client to tilt their head back to facilitate swallowing B. Encourage the client to use a straw. C. Provide oral care before meals. D. Schedule physical therapy directly before meals.

Correct Answer is C

Explanation

Choice A Reason:

Instructing the client to tilt their head back to facilitate swallowing is not appropriate. Tilting the head back can increase the risk of aspiration (food or liquid entering the airway) for individuals with dysphagia. Instead, the client should maintain an upright position while eating.

Choice B Reason:

Encouraging the client to use a straw is inappropriate. Using a straw might increase the risk of aspiration because it can bypass the control mechanisms involved in safe swallowing, especially for someone with swallowing difficulties.

Choice C Reason:

Providing oral care before meals is correct. Providing oral care before meals helps to ensure that the client's mouth is clean, reducing the risk of infections and improving taste perception, which can enhance the client's willingness and ability to eat.

Choice D Reason:

Schedule physical therapy directly before meals is incorrect. Scheduling physical therapy directly before meals might tire the client and impact their ability to eat. Fatigue can negatively affect swallowing ability, so it's generally better to allow some rest or recovery time before meals.
