Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A nurse admitting a patient with a history of emphysema reviews her past lab reports and notes that the patient's PaCO2 has been 56 to 64 mmHg. The nurse will be cautious administering oxygen because:
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A nurse preparing to start an IV on a newly admitted patient teaches the patient about the procedure and begins to prepare the site. The nurse should always start by:
Correct Answer: C
Rationale: Before preparing the skin, the nurse should ask the patient if he or she is allergic to latex or iodine, which are products commonly used in setting up for IV therapy.

Question 4 of 5
A nurse is visiting an 84-year-old woman living at home and recovering from hip surgery. The woman seems confused and has poor skin turgor, and she states that 'she stops drinking water early in the day because it is too difficult to get up during the night to go to the bathroom.' The nurse explains to the woman that:
Correct Answer: B
Rationale: The correct answer is B. In elderly patients, fluid deficits can lead to confusion and cognitive impairment. Limiting fluids can disrupt the body's balance, leading to such symptoms. Adjusting the timing of fluids can help maintain hydration without causing nighttime interruptions. Choices A, C, and D are incorrect because they do not address the underlying issue of fluid imbalance causing confusion. Choice A suggests unnecessary hospital readmission and medication adjustments. Choice C incorrectly normalizes confusion post-surgery and suggests it is safe not to urinate at night, which can exacerbate the issue. Choice D inaccurately attributes confusion to sleep loss rather than fluid imbalance.
Question 5 of 5
The nurse in the intensive care unit receives arterial blood gases (ABG) with a patient who is complaining of being 'short of breath.' The ABG has the following values: pH = 7.21, PaCO2 = 64 mm Hg, HCO3 = 24 mm Hg. The labs reflect:
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
