Hyperactive deep tendon reflexes

Hypoactive bowel sounds

Positive Chvostek's sign

Lethargy

Answer and Explanation

The Correct Answer is C

Choice A: This is incorrect because hyperactive deep tendon reflexes are not associated with low serum calcium levels. Hyperactive deep tendon reflexes can indicate hypomagnesemia, hyperthyroidism, or spinal cord injury.

Choice B: This is incorrect because hypoactive bowel sounds are not associated with low serum calcium levels. Hypoactive bowel sounds can indicate ileus, peritonitis, or opioid use.

Choice C: This is correct because positive Chvostek's sign is associated with low serum calcium levels. Positive Chvostek's sign is a facial muscle spasm that occurs when tapping on the cheek near the ear. It indicates hypocalcemia, which can be caused by hemodialysis, renal failure, or parathyroid dysfunction.

Choice D: This is incorrect because lethargy is not associated with low serum calcium levels. Lethargy can indicate hypercalcemia, dehydration, hypoglycemia, or infection.

Correct Answer is C

Explanation

Choice A reason: Isoniazid is an antitubercular drug that can cause urine to turn dark yellow or brown, not red-orange.

Choice B reason: Metoprolol is a beta-blocker that can cause urine to turn blue-green, not red-orange.

Choice C reason: Rifampin is an antitubercular drug that can cause urine to turn red-orange, as well as other body fluids such as saliva, sweat, and tears.

Choice D reason: Furosemide is a diuretic that can cause urine to become more concentrated and darker in color, but not red-orange.

A. Maintain the client on bed rest. B. Reposition the client. C. Apply a warm, moist compress to the incision area. D. Administer an additional dose of pain medication.

Correct Answer is B

Explanation

Choice A: This is incorrect because maintaining the client on bed rest can increase the risk of complications such as pneumonia, thromboembolism, or pressure ulcers. The nurse should encourage early ambulation and frequent position changes to promote healing and prevent complications.

Choice B: This is correct because repositioning the client can help relieve pressure and discomfort from the incision site. The nurse should assist the client to change positions every 2 hours and use pillows or splints to support the incision.

Choice C: This is incorrect because applying a warm, moist compress to the incision area can interfere with wound healing and increase the risk of infection. The nurse should keep the incision site clean and dry and follow the provider's orders for dressing changes.

Choice D: This is incorrect because administering an additional dose of pain medication is not necessary when the client reports a pain level of 2 on a scale of 0 to 10. The nurse should monitor the client's pain level and administer pain medication as prescribed and as needed.
