An electrolyte is a mineral or salt dissolved in the body. (Write True or False)

True

False

Answer and Explanation

The Correct Answer is A

Choice A reason: This is correct because an electrolyte is a substance that dissociates into ions when dissolved in water, and can conduct electricity. Some examples of electrolytes in the body are sodium, potassium, calcium, chloride, and bicarbonate.

Choice B reason: This is incorrect because an electrolyte is not a solid or a gas, but a dissolved substance. Electrolytes are essential for maintaining fluid balance, nerve impulses, muscle contractions, and acid-base balance in the body.

Correct Answer is A

Explanation

Choice A reason: For an average adult, the total intake should be approximately equal to the total output every day¹². Therefore, if the patient's total output is 2200 mL, the total intake should also be around 2200 mL.

Choice B reason: 3000 mL is more than the recommended daily fluid intake for an average adult, which is about 2500 mL³. If the patient's intake is higher than their output, they may develop fluid overload or edema.

Choice C reason: 3800 mL is much more than the recommended daily fluid intake for an average adult, which is about 2500 mL³. If the patient's intake is higher than their output, they may develop fluid overload or edema.

Choice D reason: 2400 mL is slightly less than the recommended daily fluid intake for an average adult, which is about 2500 mL³. However, if the patient's intake is lower than their output, they may develop dehydration or electrolyte imbalance.

A. Prepare the client for IV infusion of normal saline B. Perform Allen's test C. Encourage the client to increase breathing D. Encourage the client to slow down breathing

Correct Answer is D

Explanation

Choice A reason: This is incorrect because normal saline is not indicated for this client. Normal saline is a isotonic solution that does not alter the acid-base balance. The client has respiratory alkalosis, which is caused by hyperventilation and results in a high pH and a low PaCO2.

Choice B reason: This is incorrect because Allen's test is not relevant for this client. Allen's test is a test to assess the patency of the radial and ulnar arteries before performing an arterial blood gas (ABG) sampling or cannulation. The client already has ABG results, so there is no need to perform Allen's test.

Choice C reason: This is incorrect because increasing breathing would worsen the client's condition. Increasing breathing would cause the client to exhale more carbon dioxide, which would lower the PaCO2 and raise the pH even more. This would increase the severity of respiratory alkalosis.

Choice D reason: This is correct because slowing down breathing would help the client to correct the respiratory alkalosis. Slowing down breathing would allow the client to retain more carbon dioxide, which would increase the PaCO2 and lower the pH. This would bring the acid-base balance closer to normal.
