A nurse is caring for a client who has hypovolemic shock. Which of the following should the nurse recognize as an expected finding?

Choice A: Evaluating chest expansion is the first action that the nurse should take, because it assesses the client's respiratory status and potential for pneumothorax, which is a life-threatening condition that can result from chest trauma. The nurse should compare the movement of both sides of the chest and listen for breath sounds.

Choice B: Checking pupillary response to light is an important action, but not the first one, because it assesses the client's neurological status and potential for brain injury. The nurse should observe the size, shape, and symmetry of the pupils and their reaction to light.

Choice C: Checking the client's response to questions about place and time is another important action, but not the first one, because it assesses the client's level of consciousness and orientation. The nurse should ask the client simple questions such as their name, date, and location.

Choice D: Assessing the capillary refill is a less important action, and not the first one, because it assesses the client's peripheral circulation and tissue perfusion. The nurse should press on the client's nail beds or fingertips and observe how quickly the color returns.

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.
