ATI Exit Exam

Correct Answer: A

Rationale: The correct answer is A: 'There is no fluctuation in the water seal chamber.' In a client with a pneumothorax being treated with a chest tube, the absence of fluctuation in the water seal chamber indicates that the lung has re-expanded. This finding suggests that there is no air leak from the lung into the pleural space. Choices B and C are incorrect because continuous bubbling in the suction control chamber or tidaling in the water seal chamber would suggest ongoing air leakage, indicating that the lung has not fully re-expanded. Choice D is also incorrect as the position of the drainage system does not directly indicate lung re-expansion.

Correct Answer: C

Rationale: The correct answer is C: Activated partial thromboplastin time (aPTT). aPTT is specifically used to monitor and regulate heparin therapy as it assesses the intrinsic pathway of coagulation, which heparin affects. Options A and B, Prothrombin time (PT) and International Normalized Ratio (INR), are used to monitor warfarin therapy, not heparin. Option D, Fibrinogen levels, is not the primary test used to monitor heparin therapy.

Correct Answer: C

Rationale: The correct answer is C. Pacing spikes after the QRS complex indicate a malfunction of the pacemaker and should be reported. Choice A is not directly related to the pacemaker function. Choice B, hiccups, are common and not typically associated with pacemaker issues. Choice D, a heart rate of 90 beats per minute, is within the normal range and does not indicate a pacemaker malfunction.

Correct Answer: B

Rationale: Using a 7th-grade reading level is the most effective technique when creating education material for clients because it ensures that the content is easily understood by a wide range of individuals. Option A, emphasizing important information with bold lettering, may help draw attention but doesn't guarantee comprehension. Option C, avoiding cartoons, is not necessarily a universal rule and can sometimes make material more engaging. Option D, using words with three or four syllables, can make the material more complex and harder to understand, defeating the purpose of effective communication in education material.

Correct Answer: B

Rationale: The correct answer is B. A glucose level of 250 mg/dL indicates hyperglycemia, which is expected in DKA. However, in the context of DKA management, persistent or worsening hyperglycemia can indicate inadequate treatment response or complications, necessitating further monitoring and intervention. Potassium levels are crucial in DKA due to the risk of hypokalemia, but a level of 4.2 mEq/L is within the normal range. Bicarbonate levels are typically low in DKA, making a value of 20 mEq/L consistent with the condition. Sodium levels of 135 mEq/L are also within normal limits and not a priority for immediate reporting in the context of DKA.
