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 A

Explanation

Choice A: This is correct. Dehydration can cause electrolyte imbalance and affect the brain function, leading to confusion, dizziness, or lethargy.

Choice B: This is incorrect. Cool, clammy skin is a sign of shock, not dehydration. Dehydration can cause dry, warm skin.

Choice C: This is incorrect. Decrease in pulse rate is a sign of bradycardia, not dehydration. Dehydration can cause increase in pulse rate as the body tries to compensate for the low blood volume.

Choice D: This is incorrect. Increase in blood pressure is a sign of hypertension, not dehydration. Dehydration can cause decrease in blood pressure as the blood volume drops.

A. Apply a motion sensor mat to the client's bed. B. Move the overbed table away from the bed. C. Raise all four side rails while the client is in bed. D. Leave the television on in the client's room.

Correct Answer is A

Explanation

Choice A reason: Applying a motion sensor mat to the client's bed is an appropriate action to prevent wandering and alert the staff if the client tries to get out of bed.

Choice B reason: Moving the overbed table away from the bed is not an effective action to prevent wandering, as it does not restrict the client's mobility or provide any supervision.

Choice C reason: Raising all four side rails while the client is in bed is an inappropriate action that can increase the risk of injury or entrapment if the client attempts to climb over them.

Choice D reason: Leaving the television on in the client's room is not an effective action to prevent wandering, as it does not provide any stimulation or distraction for the client.
