BUN 8 mg/dL and creatinine 0.7 mg/dL
BUN 10 mg/dl and creatinine 0.3 mg/dl
BUN 23 mg/dl and creatinine 1.0 mg/dl

Correct Answer is A
Explanation
A. Creatinine levels rise in acute kidney injury due to impaired kidney function, as the kidneys are unable to effectively filter creatinine from the blood.
B. BUN (blood urea nitrogen) levels typically increase in dehydration due to reduced kidney perfusion, leading to decreased urine output and increased concentration of waste products in the blood.
C. Specific gravity increases in hypovolemia because urine becomes more concentrated as the body tries to conserve water.
D. Potassium levels may vary depending on the cause of polyuria, but polyuria itself does not necessarily cause hyperkalemia. It can be caused by various factors including diabetes insipidus or diabetes mellitus.
Correct Answer is C
Explanation
A. Insulin administration is not indicated for metabolic alkalosis.
B. Breathing into a paper bag is a treatment for respiratory alkalosis, not metabolic alkalosis.
C. Metabolic alkalosis can lead to cardiac dysrhythmias due to electrolyte imbalances, particularly hypokalemia. Continuous cardiac monitoring is essential to promptly identify and manage any dysrhythmias that may occur.
D. Administering sodium bicarbonate would exacerbate metabolic alkalosis and is not indicated.
