The nurse caring for a frail 92-year-old dehydrated patient should add to the plan of care:
Potential for over-hydration related to excessive thirst
Potential for diarrhea related to dehydration
Potential for pulmonary congestion related to excessive fluid intake
Potential for fall related to confusion
The Correct Answer is D
Choice A reason: This is incorrect because over-hydration is unlikely in a dehydrated patient. Over-hydration is a condition where the body has too much water, which can cause hyponatremia, edema, and cerebral swelling.
Choice B reason: This is incorrect because diarrhea is a cause, not a consequence, of dehydration. Diarrhea is the frequent and watery passage of stool, which can lead to fluid and electrolyte loss.
Choice C reason: This is incorrect because pulmonary congestion is also unlikely in a dehydrated patient. Pulmonary congestion is a condition where the lungs are filled with fluid, which can cause dyspnea, cough, and crackles.
Choice D reason: This is correct because fall is a potential complication of dehydration. Dehydration can cause confusion, dizziness, weakness, and hypotension, which can increase the risk of falling and injuring oneself.

Correct Answer is A
Explanation
Choice A reason: This is correct because respiratory acidosis is a condition where the blood pH is lower than the normal range of 7.35 to 7.45, due to impaired gas exchange or hypoventilation, which causes carbon dioxide to accumulate in the blood. COPD is a chronic lung disease that obstructs the airways and reduces the oxygen intake and carbon dioxide output. This leads to respiratory acidosis in the patient.
Choice B reason: This is incorrect because respiratory alkalosis is a condition where the blood pH is higher than the normal range of 7.35 to 7.45, due to hyperventilation, which lowers the carbon dioxide in the blood. COPD does not cause hyperventilation, but rather hypoventilation.
Choice C reason: This is incorrect because metabolic alkalosis is a condition where the blood pH is higher than the normal range of 7.35 to 7.45, due to a loss of acids or an excess of bases in the body. COPD does not affect the metabolic system directly, but rather the respiratory system.
Choice D reason: This is incorrect because metabolic acidosis is a condition where the blood pH is lower than the normal range of 7.35 to 7.45, due to an excess of acids or a loss of bases in the body. COPD does not affect the metabolic system directly, but rather the respiratory system.
Correct Answer is C
Explanation
Choice A reason: This is incorrect because this represents respiratory alkalosis, not acidosis. Respiratory alkalosis is characterized by a high pH and a low PCO2.
Choice B reason: This is incorrect because this represents a mixed disorder, not a pure respiratory acidosis. A mixed disorder occurs when both the pH and the PCO2 are abnormal, but in opposite directions.
Choice C reason: This is correct because this represents respiratory acidosis. Respiratory acidosis is characterized by a low pH and a high PCO2.
Choice D reason: This is incorrect because this represents normal values, not respiratory acidosis. Normal values for pH and PCO2 are 7.35 to 7.45 and 35 to 45 mmHg, respectively.
