A nurse is caring for a client who is 1 hr postoperative following a left hip arthroplasty. Which of the following laboratory values indicates the nurse should notify the provider?
Blood glucose 98 mg/dL
BUN 18 mg/dL
Hemoglobin 8.6 g/dL
Potassium 3.5 mEq/L
The Correct Answer is C
Choice C Hemoglobin 8.6 g/dL indicates the nurse should notify the provider because it is below the normal range of 12 to 18 g/dL and suggests blood loss or anemia, which can impair oxygen delivery to tissues and affect wound healing.
Choice a is not correct because blood glucose 98 mg/dL does not indicate the nurse should notify the provider because it is within the normal range of 70 to 110 mg/dL and does not indicate hyperglycemia or hypoglycemia, which can affect recovery.
Choice b is not correct because BUN 18 mg/dL does not indicate the nurse should notify the provider because it is within the normal range of 10 to 20 mg/dL and does not indicate renal impairment or dehydration, which can affect fluid and electrolyte balance.
Choice d is not correct because potassium 3.5 mEq/L does not indicate the nurse should notify the provider because it is within the normal range of 3.5 to 5 mEq/L and does not indicate hypokalemia or hyperkalemia, which can affect cardiac function and muscle contraction.

Correct Answer is C
Explanation
Choice A: This is incorrect. Vegetable shortening is high in saturated fat and trans fat, which can increase the risk of cardiovascular disease by raising the LDL (bad) cholesterol and lowering the HDL (good) cholesterol.
Choice B: This is incorrect. Lard is animal fat that is high in saturated fat and cholesterol, which can also increase the risk of cardiovascular disease by raising the LDL cholesterol and lowering the HDL cholesterol.
Choice C: This is correct. Canola oil is low in saturated fat and high in monounsaturated fat and omega-3 fatty acids, which can lower the risk of cardiovascular disease by lowering the LDL cholesterol and raising the HDL cholesterol.
Choice D: This is incorrect. Butter is dairy fat that is high in saturated fat and cholesterol, which can also increase the risk of cardiovascular disease by raising the LDL cholesterol and lowering the HDL cholesterol
Correct Answer is B
Explanation
Choice A reason: Applying restraints to the client is not an appropriate action, as it can cause injury or suffocation to the client during a seizure. The nurse should protect the client from harm by removing any nearby objects and padding the side rails.
Choice B reason: Administering an IV bolus of lorazepam is an appropriate action, as lorazepam is an anticonvulsant drug that can stop or shorten the duration of a seizure by enhancing the inhibitory effects of gamma-aminobutyric acid (GABA) in the brain.
Choice C reason: Placing the client in the prone position is not an appropriate action, as it can obstruct the airway and cause respiratory distress or aspiration during a seizure. The nurse should place the client in the side-lying position to facilitate drainage of oral secretions and prevent tongue biting.
Choice D reason: Inserting a tongue blade into the client's mouth is not an appropriate action, as it can cause oral trauma or choking during a seizure. The nurse should never force anything into the client's mouth during a seizure and should allow them to breathe spontaneously.
