A nurse is reviewing the ABG values of a client who has pneumonia. Which of the following findings indicates the client is developing respiratory acidosis?
PaO2 85 mmHg
pH 7.47
HCO3 25 mEq/L
PaCO2 55 mmHg
The Correct Answer is D
Choice A reason: PaO2 85 mmHg is within the normal range of 80 to 100 mmHg and does not indicate any hypoxemia or oxygen deficiency.
Choice B reason: pH 7.47 is within the normal range of 7.35 to 7.45 and does not indicate any acid-base imbalance.
Choice C reason: HCO3 25 mEq/L is within the normal range of 22 to 26 mEq/L and does not indicate any metabolic disturbance.
Choice D reason: PaCO2 55 mmHg is above the normal range of 35 to 45 mmHg and indicates respiratory acidosis, which is a condition where the lungs cannot eliminate enough carbon dioxide and the blood becomes too acidic. This can be caused by pneumonia, which can impair gas exchange and ventilation.

Correct Answer is A
Explanation
Choice A: This is correct because suction equipment is essential for clearing the airway of secretions or vomitus during or after a seizure. The nurse should have suction equipment ready and accessible at the client's bedside at all times.
Choice B: This is incorrect because backboard is not needed for a client who has a seizure disorder. Backboard is used for immobilizing the spine in case of a suspected spinal injury.
Choice C: This is incorrect because padded tongue blades are not recommended for a client who has a seizure disorder. Padded tongue blades can cause injury to the teeth, gums, or tongue if inserted during a seizure. The nurse should never force anything into the mouth of a client who is having a seizure.
Choice D: This is incorrect because wrist restraints are not indicated for a client who has a seizure disorder. Wrist restraints can cause injury or skin breakdown if applied during a seizure. The nurse should never restrain or restrict the movements of a client who is having a seizure.
Correct Answer is A
Explanation
Choice A: This is correct. Dehydration can cause electrolyte imbalance and affect the brain function, leading to confusion, dizziness, or lethargy.
Choice B: This is incorrect. Cool, clammy skin is a sign of shock, not dehydration. Dehydration can cause dry, warm skin.
Choice C: This is incorrect. Decrease in pulse rate is a sign of bradycardia, not dehydration. Dehydration can cause increase in pulse rate as the body tries to compensate for the low blood volume.
