A nurse is caring for a client who has pneumonia with dyspnea. The client's ABG results are pH 7.30, PaCO2 50 mm Hg, HCO3 26 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?

Sit in a straight-backed chair. After a total hiparthroplasty, the client should avoid sitting in chairs that are too low or too soft, as they can be difficult to rise from and can risk dislocating the new hip. The clientshould apply ice to the incision site, not moist heat, in the first few dayspostoperatively. The client should avoid adducting the hip as this can also riskdislocation of the new hip joint. Hydrogen peroxide should not be used to cleanthe surgical incision, as it can delay wound healing.

Choice A: The client shouldapply ice to the incision site, not moist heat, in the first few days postoperatively.

Choice C: The client should avoid adducting the hip as this can risk dislocation ofthe new hip joint.

The correct answer is choice D. Allow frequent rest periods.

Choice A rationale:

Encouraging fluids is not appropriate for a client with heart failure. Clients with heart failure often experience fluid overload due to the heart’s inability to pump effectively, leading to fluid retention.Encouraging additional fluid intake can exacerbate this condition, worsening symptoms such as edema and shortness of breath.

Choice B rationale:

Measuring vital signs every 8 hours may not be frequent enough for a client with heart failure, especially if they are experiencing acute symptoms.More frequent monitoring is often necessary to detect changes in the client’s condition promptly and to manage symptoms effectively.

Choice C rationale:

Obtaining weight weekly is not sufficient for a client with heart failure. Daily weight monitoring is crucial as it helps in detecting fluid retention early.Sudden weight gain can indicate worsening heart failure and the need for adjustments in treatment.

Choice D rationale:

Allowing frequent rest periods is essential for clients with heart failure. These clients often experience fatigue and decreased exercise tolerance due to reduced cardiac output.Frequent rest periods help in managing fatigue and preventing overexertion, which can worsen heart failure symptoms.
