At which serum sodium concentration might convulsions or coma occur? - ANSWER - 130 mEq/L (130 mmol/L) Normal serum concentration level ranges from 135 to 145 mEq/L (135- 145 mmol/L). When the level dips below 135 mEq/L (135 mmol/L), hyponatremia occurs. Manifestations of hyponatremia include mental confusion, muscular weakness, anorexia, restlessness, elevated body temperature, tachycardia, nausea, vomiting, and personality changes.Convulsions or coma can occur if the deficit is severe. Values of 140, 142, and 145 mEq/L (mmol/L) are within the normal range.
Which laboratory result does the nurse identify as a direct result of the client's hypovolemic status with hemoconcentration? - ANSWER - Elevated hematocrit level When hemoconcentration occurs due to a hypovolemic state, a high ratio of blood components in relation to watery plasma occurs, thus causing an elevated hematocrit level. A high white blood cell count and urine specific gravity is also noted. Other causes of an abnormal potassium level may be present.
The weight of a client with congestive heart failure is monitored daily and entered into the medical record. In a 24-hour period, the client's weight increased by 2 lb. How much fluid is this client retaining? -
ANSWER - 1 L 1 / 3

pg. 2 A 2-lb weight gain in 24 hours indicates that the client is retaining 1L of fluid.
Which nerve is implicated in the Chvostek's sign? - ANSWER - Facial
A health care provider orders an isotonic I.V. solution for a client. Which solution should the nurse plan to administer? - ANSWER - Lactated Ringer's solution
The nurse is caring for a client with laboratory values indicating dehydration. Which clinical symptom is consistent with the dehydration?
- ANSWER - Dark, concentrated urine
A client reports tingling in the fingers as well as feeling depressed. The nurse assesses positive Trousseau's and Chvostek's signs. Which decreased laboratory results does the nurse observe when the client's laboratory work has returned? - ANSWER - Calcium
Calcium deficit is associated with the following symptoms: numbness
and tingling of the fingers, toes, and circumoral region; positive Trousseau's sign and Chvostek's sign; seizures, carpopedal spasms, hyperactive deep tendon reflexes, irritability, bronchospasm, anxiety, impaired clotting time, decreased prothrombin, diarrhea, and hypotension. Electrocardiogram findings associated with hypocalcemia include prolonged QT interval and lengthened ST.
The nurse is caring for a client undergoing alcohol withdrawal. Which serum laboratory value should the nurse monitor most closely? - ANSWER - Magnesium 2 / 3

pg. 3 A client has a respiratory rate of 38 breaths/min. What effect does breathing faster have on arterial pH level? - ANSWER - Increases arterial pH
A nurse is caring for a client with metastatic breast cancer who is extremely lethargic and very slow to respond to stimuli. The laboratory report indicates a serum calcium level of 12.0 mg/dl, a serum potassium level of 3.9 mEq/L, a serum chloride level of 101 mEq/L, and a serum sodium level of 140 mEq/L. Based on this information, the nurse determines that the client's symptoms are most likely associated with which electrolyte imbalance? - ANSWER - Hypercalcemia The normal reference range for serum calcium is 8.6 to 10.2 mg/dl. A serum calcium level of 12 mg/dl clearly indicates hypercalcemia. The client's other laboratory findings are within their normal ranges, so the client doesn't have hypernatremia, hypochloremia, or hypokalemia.
A nurse is caring for a client in acute renal failure. The nurse should expect hypertonic glucose, insulin infusions, and sodium bicarbonate to
be used to treat: - ANSWER - hyperkalemia.
Hyperkalemia is a common complication of acute renal failure. It's life- threatening if immediate action isn't taken to reverse it. Administering glucose and regular insulin, with sodium bicarbonate if necessary, can temporarily prevent cardiac arrest by moving potassium into the cells and temporarily reducing serum potassium levels.
A nurse is caring for an adult client with numerous draining wounds from gunshots. The client's pulse rate has increased from 100 to 130 beats per minute over the last hour. The nurse should further assess the
