The nurse is caring for a client with respiratory alkalosis. Which arterial blood gas data does the nurse anticipate finding?

pH-7.10. CO2-78. HCO3-25

pH-7.55. C02-20. HCO3-24

pH-7.25, CO2-64, HCO3-22

Ph-7.0. CO2-72. HCO3-26

Answer and Explanation

The Correct Answer is B

Respiratory alkalosis is a condition in which the blood pH is elevated due to a decrease in the partial pressure of carbon dioxide (CO2) in the blood. This can occur when a person breathes too rapidly or deeply (hyperventilation), causing them to exhale too much CO2. In this option, the pH is elevated (normal range is 7.35-7.45), the CO2 is low (normal range is 35-45 mmHg), and the bicarbonate (HCO3) level is within the normal range (22-26 mEq/L), which are all consistent with respiratory alkalosis.

Correct Answer is B

Explanation

Daily weights provide a reliable and accurate measure of ﬂuid balance in the body. An increase in weight can indicate ﬂuid retention and the need for further intervention. While daily intake and output recordings, blood pressure and heart rate checks, and CMP lab draws can also provide useful information, daily weights are the most eﬀective way to monitor for excess ﬂuid volume in this situation.

A. Rales B. Crackles C. Rhonchi D. Stridor

Correct Answer is B

Explanation

Crackles, also known as rales, are discontinuous sounds that are typically heard during inspiration in patients with heart failure. These sounds are produced by the sudden opening of small airways and alveoli that are filled with ﬂuid or collapsed due to pulmonary congestion. The sound can be described as similar to the sound of rubbing hair between fingers or the sound of Velcro being pulled apart.

Rhonchi are continuous, low-pitched sounds that are typically heard during expiration and are caused by the movement of air through narrowed airways, such as in patients with chronic obstructive pulmonary disease (COPD). Stridor is a high-pitched, continuous sound that is typically heard during inspiration and indicates upper airway obstruction, which can be life-threatening. Neither rhonchi nor stridor are typically heard in patients with heart failure.

Therefore, based on the patient's history and symptoms, the most likely type of breathing sound to be heard on auscultation is crackles/rales.
