A patient is admitted with hypernatremia caused by being stranded on a boat in the Atlantic Ocean for five days without a fresh water source. What is this patient at risk for developing?
Stress fractures.
Cerebral bleeding.
Atrial dysrhythmias.
Pulmonary edema.
The Correct Answer is B
Cerebral bleeding. Choice A rationale:
Stress fractures are not directly related to hypernatremia. Hypernatremia is an electrolyte imbalance, and its main effects are related to cellular dehydration and neurological symptoms rather than bone fractures.
Choice B rationale:
This is the correct answer because hypernatremia can lead to severe dehydration and cause neurological complications, including cerebral bleeding. The brain cells can shrink due to water loss, causing blood vessels to rupture, leading to bleeding in the brain.
Choice C rationale:
Atrial dysrhythmias are not directly associated with hypernatremia. Hypernatremia primarily affects the central nervous system and can lead to neurological symptoms rather than cardiac dysrhythmias.
Choice D rationale:
Pulmonary edema is not a likely consequence of hypernatremia. Pulmonary edema is associated with fluid volume excess, not fluid volume deficit, which is characteristic of hypernatremia.

Correct Answer is ["B","C","D"]
Explanation
The correct answers are Choices B, C, and D.
Choice A rationale: Normal saline is not typically used to treat low phosphate levels. It is often used to treat dehydration and electrolyte imbalances that do not include hypophosphatemia.
Choice B rationale: Potassium phosphate is used to treat low phosphate levels. It directly supplements phosphate levels in the body, making it an appropriate treatment for hypophosphatemia.
Choice C rationale: Additional milk intake can help increase phosphate levels, as milk is a good source of phosphate. This is a suitable recommendation for a patient with low phosphate levels.
Choice D rationale: Increased Vitamin D intake can enhance phosphate absorption from the gastrointestinal tract, making it a beneficial treatment for a patient with low phosphate levels.
Correct Answer is ["A","C","D"]
Explanation
A, C, and D.
Choice A rationale:
The administration of sodium bicarbonate helps to correct acidosis, which can occur in chronic renal failure due to the accumulation of metabolic waste products in the absence of effective kidney function.
Choice C rationale:
Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia, which is common in chronic renal failure due to impaired potassium excretion by the kidneys.
Choice D rationale:
Insulin can be prescribed to treat hyperkalemia by promoting the uptake of potassium into cells, thereby reducing the serum potassium level. Choice B and E rationale: Dextrose 10% and furosemide (Lasix) are not appropriate treatments for hyperkalemia. Dextrose 10% is asugar solution and does not impact potassium levels, while furosemide is a loop diuretic that primarily affects sodium and water excretion, not potassium.
