The Correct Answer is []
In respiratory acidosis, there is an accumulation of carbon dioxide (CO2) in the blood due to inadequate ventilation, leading to an increase in the partial pressure of arterial carbon dioxide (PaCO2) and a decrease in pH.
This is often caused by conditions that impair ventilation, such as airway obstruction, respiratory muscle weakness, lung diseases (e.g., chronic obstructive pulmonary disease, pneumonia), or central nervous system depression (e.g., drug overdose, head injury).
Management of respiratory acidosis include bronchodilators, sodium bicarbonate, adequate ventilation, and treatment of underlying causes.

Correct Answer is B
Explanation
B. Tachycardia is a compensatory mechanism aimed at increasing cardiac output and maintaining tissue perfusion. In response to decreased perfusion, the body increases heart rate to improve circulation and oxygen delivery to tissues.
A. Hypokalemia, or low potassium levels, is not typically associated with the compensatory stage of shock. Instead, electrolyte imbalances may develop later in the progression of shock due to tissue hypoperfusion and metabolic disturbances.
C. Mottled skin, characterized by patchy discoloration due to uneven blood flow, is more commonly seen in the progressive or irreversible stages of shock. It indicates significant tissue hypoperfusion and impaired microcirculation, rather than the compensatory stage
D. This blood pressure reading is within the normal range and may be maintained during the compensatory stage of shock. Initially, blood pressure may be maintained or only slightly decreased due to compensatory mechanisms such as vasoconstriction. However, blood pressure can decrease further as shock progresses beyond the compensatory stage.
Correct Answer is D
Explanation
D Sedatives are typically administered alongside neuromuscular blockers to ensure the patient's comfort and prevent awareness during mechanical ventilation.
A The absence of a cough reflex when suctioned is expected in a patient receiving cisatracurium (Nimbex) because it is a neuromuscular blocking agent that induces paralysis. Cisatracurium inhibits skeletal muscle movement, including the muscles involved in coughing.
B An oxygen saturation between 90% to 93% is within an acceptable range for a patient in this condition.
C The lack of response to voice may indicate that the patient is sedated or experiencing effects from the neuromuscular blocking agent. However, since the patient is receiving cisatracurium to prevent asynchronous breathing with the positive pressure ventilator, it's expected that the patient will not respond to voice due to the medication-induced paralysis.
