A client who is found unresponsive has arterial blood gases drawn, and the results indicate the following:
- pH is 7.12 (normal range: 7.35-7.45)
- PaCO2 is 90 mm Hg (normal range: 35-45)
- HCO3- is 22 mEq/L (normal range: 22-26)
The nurse interprets the results as indicating which condition?
Metabolic alkalosis
Respiratory alkalosis
Respiratory acidosis
Metabolic acidosis
The Correct Answer is C
A. Metabolic alkalosis is characterized by a high pH and elevated bicarbonate levels, which is not present in these results.
B. Respiratory alkalosis would present with an increased pH and decreased PaCO2, which does not apply here.
C. The low pH (7.12) indicates acidemia, and the elevated PaCO2 (90 mm Hg) suggests hypoventilation and respiratory acidosis due to CO2 retention. The bicarbonate level is within normal limits, further supporting respiratory acidosis.
D. Metabolic acidosis would be indicated by a low pH and low bicarbonate levels; however, the bicarbonate is normal in this case, ruling out metabolic acidosis.

Correct Answer is D
Explanation
A. Elevated blood pressure is not an indication of dehydration; dehydration is more likely to cause a drop in blood pressure due to decreased blood volume.
B. Dehydration typically does not cause a low body temperature; instead, it can lead to an elevated temperature as the body conserves water.
C. Jugular vein distention is associated with fluid overload or heart failure, not dehydration.
D. Skin tenting, where the skin remains elevated after being pinched, is a classic sign of dehydration due to reduced skin elasticity.
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.
