The Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"D"}
- Compensated respiratory acidosis occurs when the lungs retain CO₂, causing acidosis, but the kidneys compensate by increasing bicarbonate (HCO₃⁻) levels. In this case, the pH is low, and the PaCO₂ is within normal limits, which does not indicate a respiratory issue or compensation. Compensation would require an elevated HCO₃⁻, which is not provided in the lab results.
- Compensated metabolic acidosis would require a low pH with a decreased PaCO₂, as the respiratory system compensates by increasing ventilation (hyperventilation) to "blow off" CO₂. Since the PaCO₂ in this case is within normal limits, no significant respiratory compensation has occurred yet, making this uncompensated metabolic acidosis instead.
- Uncompensated respiratory acidosis would present with a low pH and an elevated PaCO₂ (>45 mmHg) due to inadequate ventilation and CO₂ retention. Since the PaCO₂ here is 37 mmHg (within normal range), respiratory acidosis is unlikely. The metabolic component, rather than a respiratory problem, is driving the acidosis.
- Uncompensated metabolic acidosis is characterized by a low pH (7.23) and a normal PaCO₂ (37 mmHg), indicating a primary metabolic problem without sufficient respiratory compensation. In diabetic ketoacidosis (DKA), the lack of insulin results in fat breakdown and ketone production, leading to a drop in pH and metabolic acidosis. This client likely has DKA due to their history of type 1 diabetes and the lack of insulin administration.
- Kussmaul respirations are a compensatory response to metabolic acidosis, seen in conditions like DKA. However, they do not cause acidosis; instead, they are the body's attempt to correct it by exhaling CO₂. Since the ABG shows normal PaCO₂, there is no strong evidence of hyperventilation, suggesting compensation has not yet occurred.
- Starvation can lead to ketoacidosis due to prolonged fasting and fat metabolism, producing ketones. However, in type 1 diabetes, the primary issue is no insulin production, not caloric deprivation. The severity of metabolic acidosis in this client is more likely due to insulin deficiency rather than starvation.
- Tissue hypoxia leads to lactic acidosis, which results from anaerobic metabolism. This can be seen in conditions like sepsis or shock. However, in this case, the client has type 1 diabetes, and the more likely cause of acidosis is ketoacidosis due to insulin deficiency rather than hypoxia.
- A lack of insulin in type 1 diabetes prevents glucose uptake, forcing the body to break down fat, leading to ketone formation and metabolic acidosis. This matches the clinical scenario of a patient with a history of type 1 diabetes, hyperglycemia >500 mg/dL, and metabolic acidosis.

Correct Answer is {"A":{"answers":"A"},"B":{"answers":"A"},"C":{"answers":"A"},"D":{"answers":"B"},"E":{"answers":"B"}}
Explanation
- I will monitor my urine output and pay attention to the volume and color. Clients with DI must monitor urine output closely because polyuria and diluted urine indicate under-treatment, while sudden reduced output and darker urine may suggest fluid retention or excessive desmopressin dosing.
- I will always wear my medical alert bracelet. A medical alert bracelet is essential for emergency situations since DI can lead to severe dehydration and electrolyte imbalances if left untreated. It ensures that emergency responders are aware of the condition if the client is unable to communicate.
- I will use the same scale and wear a similar amount of clothing when I take my weekly weight. Monitoring body weight trends is crucial in DI management, as sudden weight gain may indicate fluid retention (over-treatment), while weight loss may suggest dehydration. Using a consistent method ensures accurate tracking.
- If I gain more than 2.2 lb (1 kg), I will go to the emergency department (ED). A sudden weight gain may suggest fluid retention from over-treatment, but mild fluctuations are not always an emergency. Instead, the client should report significant weight changes to their healthcare provider to assess medication adjustments.
- If I become thirstier, I may need another dose of the medication. While increased thirst may indicate under-treatment, self-adjusting the desmopressin dose is not recommended without consulting a healthcare provider. The client should track symptoms and report persistent thirst to determine if a dosage change is necessary.
Correct Answer is B
Explanation
A. Degree of pain using a 10-point scale. Pain assessment is important, but it is not the priority in an emergency trauma situation. Clients involved in motor vehicle collisions (MVCs) without a helmet are at high risk for life-threatening injuries, including hemorrhage and shock. The nurse must first assess vital signs to determine hemodynamic stability.
B. Pulse and blood pressure. The primary concern in trauma patients is circulation and perfusion. Assessing pulse and blood pressure helps determine if the client is experiencing shock, hemorrhage, or traumatic brain injury (TBI)-related autonomic dysfunction. In trauma resuscitation, the ABCs (Airway, Breathing, Circulation) guide assessment priorities, making circulatory status the first concern after ensuring airway patency.
C. Balance and coordination. A neurological assessment for balance and coordination is not a priority in a critically injured trauma patient. Severe injuries, including intracranial hemorrhage, cervical spine trauma, or internal bleeding, must be ruled out before assessing fine motor function.
D. Bilateral pupillary reaction to light. Pupillary response is part of a neurological assessment and is crucial in identifying traumatic brain injury. However, vital signs must be assessed first to determine hemodynamic stability, as untreated shock or hemorrhage can lead to rapid deterioration or death.
