The nurse reviews the arterial blood gas results of an assigned client and notes the laboratory report results
pH of 7.30, [normal pH is 7.35 to 7.45]
Paco2 of 58 mm Hg, [Normal Paco2 is 35 to 45 mm Hg]
Pao2 of 80 mm Hg. [normal is 80-100]
HCO3 of 27 mEq/L (27 mmol/L). [Normal HCO3 is 22-26]
The nurse interprets that the client has which acid-base disturbance?
Respiratory acidosis
Respiratory alkalosis
Metabolic acidosis
Metabolic alkalosis
The Correct Answer is A
A. Respiratory acidosis: The pH is low (indicating acidosis), and the Paco₂ is elevated, which signifies that carbon dioxide retention is causing the acidosis. This pattern indicates respiratory acidosis, as the elevated HCO₃ suggests a compensatory response.
B. Respiratory alkalosis: Respiratory alkalosis would show a high pH with a low Paco₂. This is not consistent with the client’s lab results.
C. Metabolic acidosis: Metabolic acidosis would show a low pH with a low HCO₃. In this case, the HCO₃ is slightly elevated, ruling out metabolic acidosis.
D. Metabolic alkalosis: Metabolic alkalosis would show a high pH with an elevated HCO₃, which does not match the client’s results.

Correct Answer is ["A","C"]
Explanation
A. Increase daily exercise: Regular physical activity helps stimulate bowel movements and can relieve constipation.
B. Be sure to take good care of your teeth: While dental health is important, it is not directly related to constipation management.
C. Incorporate more fresh fruits and vegetables in your daily intake: These foods are high in fiber, which helps to soften stool and promote regularity.
D. Avoid drinking hot liquids: This is not a standard recommendation for managing constipation; warm liquids can sometimes aid in bowel movements.
E. Increase intake of low fiber foods: This would likely worsen constipation, as low-fiber diets can contribute to harder stools.
Correct Answer is B
Explanation
A. Auscultating the area may not provide information about the dorsalis pedis pulse, which is a palpated pulse.
B. Using Doppler ultrasonography is the most appropriate next step to locate the dorsalis pedis pulse if it cannot be palpated, as it provides a non-invasive way to detect blood flow.
C. While documenting the absence of the pulse is necessary, it should be done after attempts to locate the pulse have been made.
D. It is not immediately necessary to ask a provider to assess the pulse; the nurse can use Doppler ultrasonography first to gather more information.
