1. A client with a diagnosis of diabetic ketoacidosis (DKA) is being treated in the ER. Which finding would a nurse expect to note as confirming this diagnosis?

• A. Elevated blood glucose level and a low plasma bicarbonate
• B. Decreased urine output
• C. Increased respirations and an increase in pH
• D. Comatose state

Correct answer: A

Rationale: The correct answer is A: Elevated blood glucose level and a low plasma bicarbonate. Diabetic ketoacidosis (DKA) is characterized by hyperglycemia, ketosis, and metabolic acidosis, reflected by a low plasma bicarbonate. Elevated blood glucose levels are a hallmark of DKA due to the body's inability to use glucose properly. Choices B, C, and D are incorrect. Decreased urine output is not a specific finding associated with DKA. Increased respirations and an increase in pH are not typical in DKA; in fact, respiratory compensation for the metabolic acidosis in DKA leads to Kussmaul breathing (deep, rapid breathing). A comatose state may occur in severe cases of DKA but is not a confirming finding for the diagnosis.

2. A healthcare professional is preparing to care for a client with a potassium deficit. The healthcare professional reviews the client's record and determines that the client was at risk for developing the potassium deficit because the client:

• A. Has renal failure.
• B. Requires nasogastric suction.
• C. Has a history of Addison's disease.
• D. Is taking a potassium-sparing diuretic.

Correct answer: B

Rationale: Nasogastric suction can lead to significant potassium loss due to the continuous drainage of gastric contents, increasing the risk of a potassium deficit. Choices A, C, and D do not directly result in the significant loss of potassium. Renal failure may lead to potassium retention rather than a deficit. Addison's disease is associated with adrenal insufficiency, not potassium depletion. Potassium-sparing diuretics, as the name suggests, typically help retain potassium rather than cause a deficit.

3. A nurse manager in the emergency department considers policy changes in the organization and changes in the community, and tries to predict how these may impact the functioning of the unit. Which of the following decisional activities best describes this manager's actions?

• A. Resource allocation
• B. Monitoring
• C. Job analysis and redesign
• D. Planning for the future

Correct answer: D

Rationale: The correct answer is 'Planning for the future.' In this scenario, the nurse manager is engaging in strategic planning by considering policy changes and community dynamics to forecast potential impacts on the unit's functioning. This decisional activity involves anticipating future changes, challenges, and opportunities, and preparing the unit to adapt accordingly. Choice A, 'Resource allocation,' involves distributing resources effectively to support daily operations, which is not the primary focus of the nurse manager's actions described. Choice B, 'Monitoring,' typically involves overseeing current activities and performance to ensure adherence to standards and goals, rather than proactively planning for future changes as the nurse manager is doing. Choice C, 'Job analysis and redesign,' pertains to evaluating and modifying job roles and responsibilities within the unit, which is not directly related to the strategic forecasting and planning involved in anticipating organizational and community impacts.

4. An external insulin pump is prescribed for a client with DM. The client asks the nurse about the functioning of the pump. The nurse bases the response on the information that the pump:

• A. Gives small continuous doses of regular insulin subcutaneously, and the client can self-administer a bolus with an additional dosage from the pump before each meal.
• B. Is timed to release programmed doses of regular or NPH insulin into the bloodstream at specific intervals.
• C. Is surgically attached to the pancreas and infuses regular insulin into the pancreas, which in turn releases the insulin into the bloodstream.
• D. Continuously infuses small amounts of NPH insulin into the bloodstream while regularly monitoring blood glucose levels.

Correct answer: A

Rationale: The correct answer is A. An external insulin pump delivers small continuous doses of regular insulin subcutaneously throughout the day to meet the basal insulin needs. The client can also self-administer a bolus dose with an additional dosage from the pump before each meal to cover the mealtime insulin needs. Option B is incorrect as insulin pumps do not typically release programmed doses of insulin into the bloodstream at specific intervals; instead, they infuse insulin subcutaneously. Option C is incorrect as insulin pumps are not surgically attached to the pancreas; they are worn externally. Option D is incorrect as NPH insulin is not commonly used in insulin pumps, and the pumps do not continuously infuse insulin directly into the bloodstream but rather subcutaneously.

5. A client with type 1 diabetes mellitus presents with nausea, vomiting, and abdominal pain. The nurse suspects diabetic ketoacidosis (DKA). Which of the following lab findings would confirm this diagnosis?

• A. Serum glucose of 180 mg/dL
• B. Serum bicarbonate of 22 mEq/L
• C. Blood pH of 7.25
• D. Urine specific gravity of 1.020

Correct answer: C

Rationale: A blood pH of 7.25 is a critical finding in diabetic ketoacidosis (DKA) as it indicates metabolic acidosis, which is a hallmark of this condition. In DKA, there is an accumulation of ketones in the blood, leading to increased acidity. The serum glucose level is typically elevated in DKA, often exceeding 250 mg/dL. A serum bicarbonate level less than 18 mEq/L is usually seen in DKA due to the metabolic acidosis. Urine specific gravity is not a specific indicator for DKA and may vary depending on the individual's hydration status. Therefore, the correct lab finding that confirms DKA in this scenario is a blood pH of 7.25.
