Megan's patient is on strict intake and output measurements. Her patient's total output is 2200 mL. What should the total intake be for an average adult?
2200 mL
3000 mL
3800 mL
2400 mL
The Correct Answer is A
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.

Correct Answer is A
Explanation
Choice A reason: Renal failure can cause hyperkalemia because the kidneys are unable to excrete excess potassium from the body. This can lead to high levels of potassium in the blood, which can affect the heart and muscles.
Choice B reason: Diarrhea can cause hypokalemia, not hyperkalemia, because it can lead to loss of potassium from the gastrointestinal tract. This can result in low levels of potassium in the blood, which can also affect the heart and muscles.
Choice C reason: Blood transfusion can cause hyperkalemia if the blood is old or hemolyzed, meaning that the red blood cells have broken down and released potassium into the plasma. This can increase the potassium levels in the recipient's blood.
Choice D reason: Diaphoresis, or sweating, can cause hypokalemia, not hyperkalemia, because it can lead to loss of potassium from the skin. This can also lower the potassium levels in the blood.
Correct Answer is D
Explanation
Choice A reason: This is correct because prolonged bed rest can cause hypocalcemia, or low serum calcium level. Calcium is stored in the bones and is released into the blood when the bones are stressed by weight-bearing activities. When a person is on bed rest, the bones are not stimulated and the calcium remains in the bones, leading to a decrease in serum calcium level.
Choice B reason: This is incorrect because too much butter consumption does not affect the serum calcium level directly. Butter is a source of fat and calories, which can affect the cholesterol and triglyceride levels, but not the calcium level. However, too much butter consumption can cause obesity, which can increase the risk of osteoporosis and fractures.
Choice C reason: This is incorrect because hyperparathyroidism can cause hypercalcemia, or high serum calcium level. Hyperparathyroidism is a condition where the parathyroid glands produce too much parathyroid hormone (PTH), which regulates the calcium and phosphorus balance in the body. PTH stimulates the release of calcium from the bones into the blood, leading to an increase in serum calcium level.
Choice D reason: This is incorrect because excessive ingestion of vitamin D can also cause hypercalcemia, or high serum calcium level. Vitamin D is a fat-soluble vitamin that helps the body absorb calcium from the food and supplements. When a person takes too much vitamin D, the calcium absorption is increased and the serum calcium level rises.
