What are the signs and symptoms of DKA? Select all that apply.
Hyperglycemia.
Ketonuria.
Metabolic acidosis.
Hypokalemia.
Dehydration.
Kussmaul respirations
Correct Answer : A,B,C,E,F
Choice A rationale:
Hyperglycemia is a key symptom of DKA. It occurs when there is an insufficient amount of insulin in the body to allow glucose to enter cells for use as energy. As a result, the body begins to break down fat for fuel, leading to the production of ketones and causing blood glucose levels to rise1. Normal blood glucose levels are between 4.0 to 6.0 mmol/L when fasting and up to 7.8 mmol/L two hours after eating2.
Choice B rationale:
Ketonuria, or the presence of ketones in the urine, is another symptom of DKA. When the body breaks down fat for energy, ketones are produced. If too many ketones build up in the blood, they can spill over into the urine1.
Choice C rationale:
Metabolic acidosis occurs in DKA due to the accumulation of ketones in the blood. Ketones are acidic, and when they build up in the blood, they cause the blood to become more acidic, leading to metabolic acidosis1.
Choice D rationale:
Hypokalemia is not a symptom of DKA. In fact, patients with DKA often have high potassium levels in their blood at presentation because acidosis causes potassium to move from inside the cells into the bloodstream1. However, during treatment for DKA, when insulin is administered and acidosis is corrected, potassium moves back into the cells and can lead to low potassium levels or hypokalemia1.
Choice E rationale:
Dehydration is a common symptom of DKA. High blood glucose levels lead to increased urination as the body tries to get rid of the excess glucose. This can result in dehydration1.
Choice F rationale:
Kussmaul respirations are a type of hyperventilation that occurs in DKA as the body tries to get rid of excess acids (ketones) through the lungs by breathing rapidly and deeply1.

Correct Answer is C
Explanation
When assessing an older client with left-sided heart failure (HF), the most important intervention for the practical nurse (PN) to implement is to auscultate all lung fields. Left-sided heart failure is characterized by the inability of the left ventricle to effectively pump blood, leading to fluid accumulation in the lungs. Auscultating all lung fields allows the PN to assess for the presence of abnormal lung sounds such as crackles, indicating pulmonary congestion.
Let's evaluate the other options:
a) Inspect for sacral edema.
Sacral edema is commonly associated with right-sided heart failure, not left-sided heart failure. While it is important to assess for edema in clients with heart failure, inspecting for sacral edema may not be the most immediate and crucial intervention in this specific case.
b) Measure urinary output.
Measuring urinary output is a valuable assessment in many clinical situations, but it may not be the most vital intervention in the context of left-sided heart failure. Monitoring urinary output is more relevant in assessing kidney function and fluid balance rather than directly assessing the severity of left-sided heart failure.
d) Check mental acuity.
Checking mental acuity is important in assessing the overall condition of the client, but it is not the most crucial intervention specifically related to left-sided heart failure. Mental status evaluation is more useful in identifying signs of altered mental status or potential complications, rather than directly assessing the impact of left-sided heart failure.
In summary, when assessing an older client with left-sided heart failure, the most important intervention for the practical nurse (PN) to implement is to auscultate all lung fields. This allows for the detection of abnormal lung sounds associated with pulmonary congestion, a hallmark sign of left-sided heart failure.
Correct Answer is B
Explanation
The correct answer is choice b. “Curling’s ulcer.”
Choice A rationale:
Elevated blood pressure is not a common complication specifically associated with partial-thickness burns. It may occur due to pain or stress but is not the most critical complication to anticipate.
Choice B rationale:
Curling’s ulcer, a type of stress ulcer, is a significant complication that can develop in burn patients due to the stress response and reduced blood flow to the gastrointestinal tract.
Choice C rationale:
Compartment syndrome is more commonly associated with circumferential full-thickness burns rather than partial-thickness burns.
Choice D rationale:
Excruciating pain is a symptom rather than a complication. While pain management is crucial, it is not the most critical complication to anticipate.
