A client receiving mechanical ventilation has a pH of 7.26, PaCO2 of 68 mm Hg, and a PaO2 of 92 mm Hg. Which intervention should the nurse implement?Reference Range:
Arterial Blood Gas (ABG)
pH [Adult/child: 7.35 to 7.45]
PaCO2 [Adult/child: 35 to 45 mm Hg)
HCO- [Adult/child: 21 to 28 mEq/L (21 to 28 mmol/L)] PaO2 [Adult/child: 80 to 100 mm Hg)

Increase rate of ventilation.

Decrease expiratory flow time.

Increase ventilator tidal volume.

Decrease expiratory pressure.

Answer and Explanation

The Correct Answer is A

Rationale

A. The client's pH is low (acidotic), and the PaCO2 is high (respiratory acidosis). Increasing the rate of ventilation (respiratory rate) can help to decrease PaCO2 by increasing alveolar ventilation, thereby helping to correct respiratory acidosis.

B. Expiratory flow time affects the time available for exhalation. While this may affect the overall mechanics of ventilation, it is not directly targeting the primary issue of elevated PaCO2 and acidosis.

C. Increasing tidal volume increases the volume of air delivered with each breath. This can improve ventilation efficiency but may not address the underlying problem of elevated PaCO2 unless it leads to increased minute ventilation.

D. Expiratory pressure is related to positive end-expiratory pressure (PEEP), which helps maintain alveolar recruitment and improve oxygenation. Decreasing expiratory pressure may not directly address the elevated PaCO2 and acidosis.

Correct Answer is {"A":{"answers":"A"},"B":{"answers":"C"},"C":{"answers":"B"},"D":{"answers":"B"}}

Explanation

Client Statement: A. The client seems unemotional when talking about needing to rebuild her house.

Suppression fits here because the client appears detached or unemotional when discussing the significant emotional task of rebuilding her house after it collapsed. This suggests a deliberate effort to suppress or minimize the emotional impact of the situation.

Client Statement: C. The client discusses moving to Hawaii instead of returning to rebuild her house.

The client's discussion of moving to Hawaii instead of facing the reality of rebuilding her house reflects a form of fantasy. It suggests a retreat into an idealized scenario (moving to a distant, idyllic location) to avoid dealing directly with the trauma and stress associated with rebuilding her home.

Client Statement: B. The client says that she sometimes forgets why she is in the hospital.

Isolation can be inferred here because the client's statement about forgetting why she is in the hospital may indicate a psychological distancing or detachment from the traumatic events that led her there. It suggests a coping mechanism where she separates her emotional distress (related to the house collapse) from the practical reality of being hospitalized and receiving treatment.

Client Statement: D. The client is frightened that the hospital will burn down.

This statement fits into the defense mechanisms of fantasy. The client encounters thoughts of the hospital burning and her house burns down.

A. Fluid resuscitation due to capillary leaking. B. Replacement of insensible water loss. C. Extension of plasma until blood is available. D. Restoration of electrolyte balance.

Correct Answer is A

Explanation

Rationale

A. In the early phase following a burn injury, there is increased capillary permeability due to the release of inflammatory mediators. This results in fluid shifting from the intravascular space into the interstitial space (capillary leaking), leading to hypovolemia and decreased tissue perfusion. Administering crystalloid fluids helps to restore intravascular volume (fluid resuscitation) and improve tissue perfusion.

B. Burn injuries can lead to increased evaporative water loss through damaged skin (insensible water loss). Crystalloid fluids help to replace this lost fluid and maintain adequate hydration status in the client.

C. In severe burn injuries, there may be a need for blood transfusions due to hemorrhage or ongoing blood loss. Crystalloid fluids can help to extend plasma volume temporarily until blood products are available for transfusion, thereby supporting circulatory stability.

D. Burn injuries can disrupt electrolyte balance due to fluid shifts and tissue damage. Crystalloid fluids contain electrolytes (such as sodium and chloride) that help to restore and maintain electrolyte balance in the body.
