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.

Correct Answer is D
Explanation
Hyperactive bowel sounds refer to an increased intensity, frequency, and loudness of bowel sounds. They are typically described as loud, high-pitched, and occurring more frequently than normal. This can indicate increased bowel motility and may be associated with conditions such as diarrhea, gastroenteritis, or bowel obstruction.
No sounds heard after listening for 3 to 5 minutes: This describes absent or hypoactive bowel sounds, where no sounds or very few sounds are heard. It can indicate decreased or absent bowel motility and may be seen in conditions such as ileus or peritonitis.
Sounds are soft and at a rate of 1/min: This describes normal or hypoactive bowel sounds, where the sounds are relatively quiet and occur at a slower rate (usually 5-34 sounds per minute). It may be observed in situations such as during sleep, after eating, or in certain conditions like constipation or paralytic ileus.
Indicates decreased motility: This is an inaccurate statement for hyperactive bowel sounds.
Hyperactive bowel sounds actually indicate increased motility, as mentioned earlier. Decreased motility would be associated with hypoactive or absent bowel sounds.
Correct Answer is D
Explanation
d. Muscle pain.
Atorvastatin is a medication used to lower cholesterol levels in the blood. One of the potential adverse effects of atorvastatin is myopathy, a condition characterized by muscle pain, weakness, and tenderness. In severe cases, myopathy can progress to rhabdomyolysis, a potentially life-threatening condition in which muscle breakdown products are released into the bloodstream and can cause kidney damage.
Therefore, the nurse should instruct the client to monitor for muscle pain, weakness, or tenderness and report these symptoms to the healthcare provider immediately. Hypoglycemia, palpitations, and daytime drowsiness are not commonly associated with atorvastatin use and would not require immediate reporting to the healthcare provider.
