A nurse is assessing a client in the oliguric phase of acute kidney injury. Which of the following findings should the nurse expect?
Hypomagnesemia
Hyperkalemia
Decreased creatinine level
Increased glomerular filtration rate (GFR)
The Correct Answer is B
Choice A Reason: This choice is incorrect because hypomagnesemia is not a common finding in the oliguric phase of acute kidney injury. Hypomagnesemia is a condition in which the serum magnesium level is lower than normal (less than 1.5 mEq/L). It may be caused by various factors such as malnutrition, diarrhea, diuretics, or alcohol abuse. It may cause symptoms such as muscle weakness, tremors, tetany, or cardiac arrhythmias.
Choice B Reason: This choice is correct because hyperkalemia is a common finding in the oliguric phase of acute kidney injury. Hyperkalemia is a condition in which the serum potassium level is higher than normal (more than 5 mEq/L). It may be caused by reduced renal excretion of potassium due to decreased urine output (oliguria). It may cause symptoms such as muscle weakness, paresthesia, bradycardia, or cardiac arrest.
Choice C Reason: This choice is incorrect because decreased creatinine level is not a common finding in the oliguric phase of acute kidney injury. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys and excreted in urine. A normal creatinine level ranges from 0.6 to 1.2 mg/dL for men and 0.5 to 1.1 mg/dL for women. In acute kidney injury, creatinine level usually increases due to reduced renal function and impaired clearance of creatinine.
Choice D Reason: This choice is incorrect because increased glomerular filtration rate (GFR) is not a common finding in the oliguric phase of acute kidney injury. GFR is a measure of how well
the kidneys filter blood and remove waste products.
A normal GFR range is 90,to 120 mL/min/1.73 m2. In acute kidney injury, GFR usually decreases due to reduced blood flow,to,the kidneys or damage to the glomeruli, which are the tiny blood vessels that filter blood in the kidneys.

Correct Answer is B
Explanation
Choice A Reason: This choice is incorrect because oral hypoglycemic medications are not effective for treating DKA. Oral hypoglycemic medications are drugs that lower the blood glucose level by stimulating insulin secretion or increasing insulin sensitivity. They may be used for clients who have type 2 diabetes mellitus, but they do not work for clients who have type 1 diabetes mellitus or DKA.
Choice B Reason: This choice is correct because 0.9% sodium chloride IV bolus is an effective treatment for DKA. 0.9% sodium chloride is an isotonic solution that contains the same concentration of solutes as blood plasma. It may be used for clients who have fluid loss, dehydration, or shock. In DKA, the body breaks down fat for energy due to insulin deficiency or resistance, resulting in high levels of ketones and acids in the blood. This causes osmotic diuresis, dehydration, electrolyte imbalance, and metabolic acidosis. Therefore, administering 0.9% sodium chloride IV bolus can help to restore fluid volume and correct electrolyte imbalance.
Choice C Reason: This choice is incorrect because dextrose 5% in 0.45% sodium chloride is not indicated for treating DKA. Dextrose 5% in 0.45% sodium chloride is a hypertonic solution that contains more solutes than blood plasma. It may be used for clients who have hyponatremia, cerebral edema, or malnutrition, but it can worsen hyperglycemia and osmotic diuresis in clients who have DKA.
Choice D Reason: This choice is incorrect because glucocorticoid medications are not indicated for treating DKA. Glucocorticoid medications are drugs that mimic the effects of cortisol, a hormone that regulates stress response and inflammation. They may be used for clients who have allergic reactions, asthma, or autoimmune diseases, but they can increase blood glucose levels and inhibit insulin action in clients who have DKA.
Correct Answer is D
Explanation
Choice A Reason: This choice is incorrect because it reflects the nurse's feelings rather than focusing on the client's needs. Saying "That's a hurtful thing to say" may make the client feel guilty or defensive, and it does not address the underlying cause of the client's anger or frustration.
Choice B Reason: This choice is incorrect because it sounds accusatory and confrontational rather than empathetic and supportive. Asking "Why would you say such a thing?" may make the client feel judged or criticized, and it does not explore the client's feelings or concerns.
Choice C Reason: This choice is incorrect because it dismisses the client's feelings rather than acknowledging them. Saying "Well, that's your opinion" may make the client feel ignored or invalidated, and it does not show respect or compassion for the client.
Choice D Reason: This choice is correct because it invites the client to express their feelings and concerns rather than shutting them down. Saying "Tell me more about that" may make the client feel heard and understood, and it may help to identify the source of their anger or frustration. The nurse can then use therapeutic communication skills such as active listening, reflecting, clarifying, or validating to establish rapport and trust with the client.
