During respiratory compensation for metabolic alkalosis, breathing becomes slower and shallower.

Correct Answer: B

Rationale: The correct answer is B: FALSE. During respiratory compensation for metabolic alkalosis, breathing actually becomes faster and deeper to expel excess carbon dioxide and increase blood pH. Slower and shallower breathing would exacerbate alkalosis by retaining more CO2. Choice A is incorrect because it contradicts the physiological response to metabolic alkalosis. Choices C and D are not applicable since they do not provide any useful information regarding the question.

Correct Answer: A

Rationale: The correct answer is A because in a patient with a massive burn injury, the most concerning assessment data would be related to the extent and depth of the burns, the presence of airway compromise, and signs of infection or sepsis. These factors can significantly impact the patient's prognosis and require immediate intervention. Choice B is not the most concerning as urine output of 30 mL/hr may be expected in a burn patient due to fluid shifts and decreased perfusion. Choice C indicates hypotension, which is concerning but not as immediate as assessing the extent and severity of the burns. Choice D, while indicating inadequate fluid intake, is not the most critical assessment in this scenario compared to evaluating the burn injury itself and potential complications. Therefore, choice A is the correct answer as it focuses on the most critical aspect of care for a patient with a massive burn injury.

Correct Answer: C

Rationale: The correct action is to start the prescribed PRN oxygen at 2 to 4 L/min. In diabetic ketoacidosis, rapid, deep respirations are a compensatory mechanism for metabolic acidosis. Administering oxygen helps improve oxygenation and reduces the work of breathing. Encouraging deep slow breaths (choice B) may worsen the patient's condition by interfering with the compensatory mechanism. Giving lorazepam (choice A) is unnecessary and could potentially depress the respiratory drive. Administering fluid bolus and insulin (choice D) are essential treatments for diabetic ketoacidosis, but addressing the respiratory distress with oxygen takes priority in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Skim Milk. Skim milk is high in phosphorus, which is not suitable for a patient on a low phosphate diet due to renal failure. The rationale is to limit phosphorus intake to prevent further complications. Grape juice (B), tea (C), and mixed green salad (D) are lower in phosphorus compared to skim milk and can be included in a low phosphate diet.

Correct Answer: B

Rationale: The correct answer is B: Test for presence of Chvostek's sign. After a thyroidectomy, tingling around the mouth could indicate hypocalcemia, which can lead to tetany. Chvostek's sign is a test for hypocalcemia, where facial twitching occurs when the facial nerve is tapped. This assessment is crucial to identify potential complications and initiate timely interventions. Incorrect choices: A: Verify the serum potassium level - While electrolyte imbalances can occur post-thyroidectomy, hypocalcemia is more likely to cause the tingling sensation around the mouth. C: Observe for blood on the neck dressing - While assessing for bleeding is important, it does not directly address the tingling sensation reported by the patient. D: Confirm a prescription for thyroid replacement - While important for long-term management post-thyroidectomy, it does not address the immediate concern of tingling sensation related to hypocalcemia.
