A nurse is caring for a client who has a prescription for warfarin. Which of the following laboratory tests should the nurse monitor?
Triiodothyronine
Blood urea nitrogen
Arterial blood gases
Prothrombin time
The Correct Answer is D
Prothrombin time.
Explanation:
When a client is prescribed warfarin, monitoring the prothrombin time (PT) and the International Normalized Ratio (INR) is crucial. Warfarin is an anticoagulant medication that affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time and INR helps determine the client's blood's ability to clot and the appropriate dosage of warfarin to maintain the desired therapeutic range.
Option a (Triiodothyronine) is a thyroid hormone and is not directly related to warfarin therapy.
Option b (Blood urea nitrogen) is a measure of kidney function and is also not directly related to warfarin therapy.
Option c (Arterial blood gases) is a measure of oxygen and carbon dioxide levels in the blood and is not related to warfarin therapy.

Explanation
The cervical cap should be left in place for a minimum of 6 hours after intercourse but should not exceed a total of 48 hours of continuous use. Leaving it in place for longer periods may increase the risk of toxic shock syndrome (TSS) and other potential complications. Using a cervical cap in combination with a spermicide is the recommended practice for maximizing its effectiveness. Spermicide helps immobilize or kill sperm, providing an additional barrier against pregnancy when used with the cervical cap.
Using the cervical cap during the menstrual cycle is not a recommended practice for contraception. The cervical cap is primarily used during sexual activity as a barrier method of contraception and is not specifically designed for use during menstruation.
While it is important for the provider to initially fit and size the cervical cap for the client, routine checks every 6 months are not necessary. However, it is still important for the client to regularly inspect the cap for any signs of damage or deterioration and replace it as needed.
Correct Answer is C
Explanation
Diminished pulses on the affected extremity. This finding may indicate compromised circulation, which is
a serious complication that requires immediate intervention.
Option a. Ecchymosis on the inner left thigh may be a concerning finding, but it is not as urgent as diminished pulses. Ecchymosis may be a result of trauma during cast application and may resolve on its own.
Option b. One fingerbreadth of space between the cast and the skin is a normal finding and indicates that the cast is not too tight.
Option d. Client report of muscle spasms of the left leg is a common complaint in clients with casts and may
be addressed with medication or other interventions, but it is not as urgent as diminished pulses.
