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 C
Explanation
PacO2 50 mm Hg. Choice A rationale:
Potassium levels are not directly related to respiratory acidosis. Potassium levels may be affected in certain conditions, but they are not specific indicators of respiratory acidosis.
Choice B rationale:
HCO3- (bicarbonate) levels may be elevated in metabolic alkalosis, not respiratory acidosis. In respiratory acidosis, the primary abnormality is an increased PacO2, not HCO3-.
Choice C rationale:
The partial pressure of carbon dioxide (PacO2) is a key parameter in diagnosing respiratory acidosis. In this case, a PacO2 of 50 mm Hg suggests hypoventilation and an excess of carbon dioxide in the blood, contributing to acidosis.
Choice D rationale:
The pH level given (pH 7.45) is within the normal range, which contradicts the diagnosis of respiratory acidosis. In respiratory acidosis, the pH would be expected to be below the normal range of 7.35-7.45 due to increased carbon dioxide levels.
Correct Answer is ["C","D","E"]
Explanation
The correct answer is choiceC. Monitor the injection site for redness,D. Use an infusion controller for the IV, andE. Monitor fluid intake and output.
Choice A rationale:
Adding the ordered dose to the IV hanging is incorrect because potassium chloride should never be added to an already hanging IV solution due to the risk of uneven distribution and potential overdose.
Choice B rationale:
Administering the dose IV push over 3 minutes is incorrect because potassium chloride should never be given by direct IV injection.It must always be diluted and administered slowly to prevent cardiac complications.
Choice C rationale:
Monitoring the injection site for redness is correct because potassium chloride can cause irritation and phlebitis at the injection site.
Choice D rationale:
Using an infusion controller for the IV is correct because it ensures the potassium chloride is administered at a controlled rate, reducing the risk of rapid infusion and potential cardiac issues.
Choice E rationale:
Monitoring fluid intake and output is correct because it helps assess the patient’s overall fluid balance and detect any signs of fluid overload or deficit, which is crucial when administering potassium.
