A nurse is collecting data from a client who is 18 hr postpartum. The nurse notes that the client is in the "taking-in phase" of maternal adjustment. Which of the following manifestations should the nurse expect?

Choice A Reason:

Pain sensation is incorrect. While assessing pain is important, it's generally secondary to addressing the life-threatening cardiac issues in hypothermia. Pain assessment can be done once the client's core temperature is stabilized.

Choice B Reason:

Urinary output is incorrect. Monitoring urinary output is essential for assessing kidney function and fluid balance, but it is not as immediately critical as assessing and addressing cardiac concerns.

In a client with hypothermia, the priority for the nurse to monitor is:

Choice C Reason:

Heart rhythm is correct. Hypothermia can affect the electrical conductivity of the heart, potentially leading to life-threatening arrhythmias. Monitoring the client's heart rhythm is essential to detect any abnormalities and intervene promptly if necessary. While all the listed parameters are important, the cardiac status takes precedence due to the immediate threat it poses to the client's life.

Choice D Reason:

- Muscle strength is incorrect. Monitoring muscle strength is important to assess the client's overall neurological status, but it's not the top priority when there is a risk of life-threatening arrhythmias due to hypothermia.

d. Prothrombin time.

Explanation:

Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. Therefore, it is important to monitor the client's clotting ability to ensure that the medication is working properly and not causing any adverse effects.

The laboratory test that is used to monitor warfarin therapy is the prothrombin time (PT), which measures the time it takes for the blood to clot. The nurse should monitor the client's PT regularly and adjust the dosage of warfarin as necessary to maintain the 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.
