Exhibits
For each assessment finding, click to specify if the assessment finding is consistent with diabetic ketoacidosis (DKA) or hyperglycemic-hyperosmolar state (HHS). Each finding may support more than 1 disease process.
Urine ketones
Creatinine greater than expected reference range
Blood glucose greater than expected reference range
Skin turgor
Blood pH greater than expected reference range
The Correct Answer is {"A":{"answers":"A"},"B":{"answers":"A,B"},"C":{"answers":"A,B"},"D":{"answers":"A,B"},"E":{"answers":"B"}}
- Urine ketones:
They are commonly present in DKA due to the breakdown of fats as an alternative energy source when insulin is insufficient. Ketones in urine are a hallmark sign of DKA.
Ketones may not be present in urine in HHS because insulin levels are sufficient to prevent excessive breakdown of fats. Therefore, urine ketones are more specific to DKA.
- Creatinine greater than expected reference range
DKA: In DKA, dehydration and electrolyte imbalances can lead to acute kidney injury (AKI), resulting in elevated creatinine levels.
HHS: Elevated creatinine can also occur in HHS due to severe dehydration and reduced kidney perfusion.
- Blood glucose greater than expected reference range:
DKA: Extremely high blood glucose levels (typically >250 mg/dL) are a hallmark of DKA due to insulin deficiency and the resultant inability to transport glucose into cells for energy.
HHS: Similar to DKA, HHS is characterized by extremely high blood glucose levels (often >600 mg/dL). Therefore, elevated blood glucose levels are consistent with both DKA and HHS.
- Skin turgor
DKA: Decreased skin turgor is indicative of dehydration, which is common in DKA due to excessive urination (polyuria) and fluid loss.
HHS: Similarly, decreased skin turgor can also be seen in HHS due to profound dehydration caused by excessive hyperglycemia and osmotic diuresis.
- Blood pH greater than expected reference range
DKA: DKA is characterized by metabolic acidosis, leading to a decreased blood pH (<7.35). Therefore, a pH greater than expected reference range would not be typical for DKA.
HHS: HHS, on the other hand, is characterized by severe hyperglycemia without significant ketoacidosis. Patients with HHS can have a normal or even elevated blood pH (>7.45) due to compensation mechanisms and absence of significant acidosis.

Correct Answer is C
Explanation
C. Restlessness and agitation can be early signs of increased ICP. They result from the brain's attempt to compensate for the increasing pressure. Restlessness may indicate discomfort or confusion caused by cerebral edema or pressure on brain structures.
A Projectile vomiting can occur with increased ICP due to stimulation of the vomiting center in the brainstem as a response to pressure on the brain. It is a symptom that may indicate a more advanced increase in ICP rather than an early manifestation.
B. Papilledema refers to swelling of the optic disc due to increased intracranial pressure transmitting through the optic nerve sheath. It is typically a late manifestation of increased ICP rather than an early one. It requires time for pressure to build up and affect the optic nerve.
D. Decorticate posturing is a type of abnormal posture that can occur with severe brain injury or increased ICP. It involves flexion of the arms, wrists, and fingers with adduction of the upper extremities and extension of the lower extremities. This is typically a later sign of increased ICP
Correct Answer is D
Explanation
D. A weight loss of 1.8 kg (4 lb) in the past 24 hours indicates effective diuresis (urine output) and reduction in fluid volume, which is the therapeutic goal of furosemide in treating pulmonary edema.
A Furosemide is a loop diuretic that typically causes a decrease in blood pressure by promoting the excretion of excess fluid and sodium from the body.
B. Adventitious breath sounds such as crackles (rales) indicate the presence of fluid in the lungs, which is a characteristic finding in pulmonary edema.
C. A respiratory rate of 24 breaths per minute is within normal range for an adult at rest. While this respiratory rate is not abnormal, it also does not directly indicate whether furosemide is effective in treating pulmonary edema.
