A client who is experiencing respiratory distress is admitted with respiratory acidosis.

Which pathophysiological process supports the client's respiratory acidosis?

Choice A rationale:

Hypothermia is a condition in which the body's core temperature falls below 95°F (35°C). It is not directly indicated by the client's vital signs as presented in the question.

Other factors that would more strongly suggest hypothermia include exposure to cold environments, immersion in cold water, or impaired thermoregulation due to conditions like hypothyroidism or alcohol intoxication.

Choice C rationale:

Hypotension is a condition in which blood pressure is abnormally low. It is also not directly indicated by the client's vital signs as presented in the question.

Hypertension, on the other hand, is a condition in which blood pressure is abnormally high.

The client's history of hypertension, and the fact that he takes enalapril (an antihypertensive medication), suggests that he may be more likely to experience hypertension than hypotension.

Choice D rationale:

Hypertension, as mentioned above, is a condition in which blood pressure is abnormally high.

While it's possible that the client is experiencing hypertension, the question specifically asks about the condition indicated by the client's vital signs.

Tachypnea, or rapid breathing, is a more direct indication of the client's respiratory distress, which is a common symptom of pneumonia.

Choice B rationale:

Tachypnea is the most likely condition indicated by the client's vital signs.

Tachypnea is often a sign of respiratory distress, which can be caused by a variety of conditions, including pneumonia. When a person has pneumonia, their lungs become inflamed and filled with fluid, making it difficult to breathe.

This can lead to rapid, shallow breathing, which is called tachypnea.

Other signs of respiratory distress that may be present in a client with pneumonia include: Coughing

Wheezing Chest pain

Feeling short of breath

Use of accessory muscles to breathe (e.g., muscles in the neck and chest) Nasal flaring

Cyanosis (a bluish tint to the skin)

The most likely diagnosis for this client isB. Pulmonary embolism and postpartum hemorrhage.

Here’s why:

1. Postpartum Hemorrhage:
   • The client has a large amount of lochia rubra, indicating significant blood loss.
   • Hemoglobin and hematocrit levels are low (7.5 g/dL and 22%, respectively), which is consistent with significant blood loss.
   • Symptoms like feeling lightheaded, pale appearance, and cool, clammy skin further support this diagnosis.
2. Pulmonary Embolism:
   • The client is experiencing shortness of breath, using accessory muscles to breathe, and has an oxygen saturation of 88% on room air.
   • Elevated D-dimer levels (1.5 µg/mL) suggest the presence of a clot.
   • Arterial Blood Gas (ABG) results show a low PaO2 (60 mmHg) and a slightly acidic pH (7.32), which can be seen in pulmonary embolism.
   • The client reports a feeling of tightness in her chest and has a rapid heart rate (120 beats per minute), which are also indicative of a pulmonary embolism.
