ATI Exit Exam RN

Correct Answer: A

Rationale: The best method to monitor fluid balance in a patient receiving diuretics is to monitor daily weight. Daily weighing is a precise way to assess changes in fluid status as it reflects variations in total body water. Monitoring intake and output (choice B) is also important but may not provide as accurate a measurement as daily weight. Monitoring blood pressure (choice C) is essential but does not directly measure fluid balance. Monitoring edema (choice D) is helpful to assess fluid status visually but may not be as sensitive as daily weight measurements in detecting subtle changes in fluid balance.

Correct Answer: B

Rationale: In chronic obstructive pulmonary disease, there is impaired gas exchange, leading to retention of carbon dioxide (CO2) and subsequent respiratory acidosis. A PaCO2 of 55 mm Hg is higher than the normal range (35-45 mm Hg) and is indicative of respiratory acidosis in COPD. Choices A, C, and D are not typically associated with COPD. PaO2 may be decreased, HCO3 may be elevated to compensate for acidosis, and pH may be lower than 7.35 due to respiratory acidosis in COPD.

Correct Answer: A

Rationale: Administering oxygen is crucial for a patient presenting with confusion after surgery because it helps alleviate potential hypoxia, which can be a common cause of confusion in the postoperative period. While repositioning the patient, administering IV fluids, and performing a neurological assessment are important nursing interventions in certain situations, addressing hypoxia by administering oxygen takes priority in this case to ensure an adequate oxygen supply to the brain and other vital organs.

Correct Answer: D

Rationale: The correct answer is D. A client presenting with symptoms of a stroke, such as slurred speech, disorientation, and headache, requires immediate attention due to the possibility of a neurological emergency. Choices A, B, and C, although concerning, do not present with symptoms as urgent as those of a potential stroke. Dislocated shoulder, sickle cell disease with joint pain, and confusion with febrile illness can be addressed after ensuring the client with stroke-like symptoms receives prompt evaluation and intervention.

Correct Answer: C

Rationale: A sodium level of 125 mEq/L indicates hyponatremia, which can lead to hypotension. Hyponatremia is associated with signs such as confusion and weakness, rather than increased appetite, dry mucous membranes, or hyperreflexia. Therefore, the nurse should expect hypotension as a finding in a client with a sodium level of 125 mEq/L.
