A client experiencing a severe anxiety attack and hyperventilating presents to the emergency department. The nurse would expect the client's pH value to be

7.50

A patient's serum sodium concentration is within the normal range. What should the nurse estimate the serum osmolality to be?

275-300 mOsm/kg

A client with excess fluid volume and hyponatremia is in a comatose state. What are the nursing considerations concerning fluid replacement?

Administer small volumes of a hypertonic solution.

The emergency department (ED) nurse is caring for a client with a possible acid-base imbalance. The physician has ordered an arterial blood gas (ABG). What is one of the most important indications of an acid-base imbalance that is shown in an ABG?

Bicarbonate

A client has a respiratory rate of 38 breaths/min. What effect does breathing faster have on arterial pH level?

Increases arterial pH

The nurse is caring for a client undergoing alcohol withdrawal. Which serum laboratory value should the nurse monitor most closely?

A client with cancer is being treated on the oncology unit for bilateral breast cancer. The client is undergoing chemotherapy. The nurse notes the client's serum calcium concentration is 12.3 mg/dL (3.08 mol/L). Given this laboratory finding, the nurse should suspect that the

A client admitted with acute anxiety has the following arterial blood gas (ABG) values: pH, 7.55; partial pressure of arterial oxygen (Pa02), 90 mm Hg; partial pressure of arterial carbon dioxide (PaCO,), 27 mm Hg; and bicarbonate (HCO3 ), 24 mEq/L. Based on these values, the nurse suspects:

Respiratory alkalosis

A client comes to the emergency department with status asthmaticus. His respiratory rate is 48 breaths/minute, and he is wheezing. An arterial blood gas analysis reveals a pH of 7.52, a partial pressure of arterial carbon dioxide (PaCO,) of 30 mm Hg, Pa02 of 70 mm Hg, and bicarbonate (HCO3??') of 26 mEq/L. What disorder is indicated by these findings?

Respiratory alkalosis

Which of the following arterial blood gas results would be consistent with metabolic alkalosis?

A nurse is reviewing a report of a client's routine urinalysis. Which value requires further investigation?

Urine pH of 3.0

active transport

A client has the following arterial blood gas (ABG) values: pH, 7.12; partial pressure of arterial carbon dioxide (PaCO2), 40 mm Hg; and bicarbonate (HCO3-), 15 mEq/L. These ABG values suggest which disorder?

metabolic acidosis

Before seeing a newly assigned client with respiratory alkalosis, a nurse quickly reviews the client's medical history. Which condition is a predisposing factor for respiratory alkalosis?

extreme anxiety

Early signs of hypervolemia include

increased breathing effort and weight gain

With which condition should the nurse expect that a decrease in serum osmolality will occur?

kidney failure

A client with an intravenous infusion is rubbing his arm. The nurse assesses the site and decides to discontinue the current infusion because of concern that the client has developed phlebitis. Which of the following clinical manifestations would the nurse assess with phlebitis? Select all that apply.
