A patient is hypoventilating and retaining carbon dioxide. On which acid-base imbalance should the nurse focus when caring for this patient?

A. Dyspnea: Dyspnea, or difficulty breathing, can be a sign of fluid volume excess. Fluid overload can cause pulmonary congestion and lead to respiratory distress. This is a critical manifestation that should be reported.

B. Edema: Edema is a common sign of fluid retention, especially in the lower extremities, and is indicative of fluid volume excess. This should be monitored and reported if observed during the transfusion.

C. Bradycardia: Bradycardia is typically not a sign of fluid volume excess. In fluid volume excess, the heart often tries to compensate for the increased fluid by increasing its rate (tachycardia) to maintain cardiac output, or the rate might remain relatively normal.

D. Hypertension: Hypertension, or high blood pressure, can occur with fluid volume excess as the extra fluid in the circulatory system increases the workload on the heart and raises blood pressure. This is a critical sign of fluid overload that requires reporting.

E. Weakness: Weakness can occur in a variety of conditions, including fluid volume excess, but it is a nonspecific symptom. It is less directly associated with fluid overload compared to the other findings like dyspnea, edema, and hypertension.

A. An infant with temperature of 102.2° F and diarrhea for 3 days: Infants are vulnerable to dehydration and fluid imbalances, which can quickly become life-threatening. A fever of 102.2°F combined with diarrhea for three days raises concern for potential severe dehydration, infection, or sepsis, which requires immediate attention.

B. A teenager with a sprained ankle and excessive edema: While the teenager’s condition is painful, a sprained ankle and excessive edema are generally not life-threatening. This condition can be treated after more urgent cases are addressed.

C. A middle-aged adult with abdominal pain who is moaning and holding her stomach: While abdominal pain may indicate a serious condition, the patient's symptoms don't necessarily suggest an immediate life-threatening situation, particularly if vital signs are stable.

D. An older adult with nausea and vomiting for 3 days with blood pressure 112/60: The blood pressure is within normal limits and while nausea and vomiting for three days are concerning, this patient’s condition is not immediately life-threatening.
