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
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 A
Explanation
The client's greenish-yellow sputum with a musty odor may indicate an infection, such as pneumonia or bronchitis, which can affect the client's lung function. By auscultating bilateral breath sounds, the nurse can assess for the presence of abnormal lung sounds, such as crackles or wheezing, which may indicate further respiratory compromise.
While obtaining a blood culture for tuberculosis (option b) may be appropriate in certain circumstances, the client's sputum color and odor do not necessarily indicate tuberculosis as the cause of their respiratory symptoms.
Requesting pulmonary function studies (option c) may also be beneficial in assessing the client's lung function, but this is not the priority assessment in this situation.
Finally, while documenting the findings (option d) is an important aspect of nursing care, it is not the priority action when the client is presenting with signs of compromised lung function.
Correct Answer is C
Explanation
A PICC line is a long, thin tube that’s inserted through a vein in your arm and passed through to the larger veins near your heart 1. If the PICC line is touching a chamber of the heart, it is most likely touching the right atrium 2.
