A nurse is reviewing the ABG results of a client with chronic emphysema. Which result suggests the need for further treatment?

Correct Answer: B

Rationale: The correct answer is B. A PaCO2 level of 55 mm Hg is elevated, indicating carbon dioxide retention, a common complication of emphysema that necessitates intervention. Elevated PaCO2 can lead to respiratory acidosis, reflecting inadequate ventilation. Choices A, C, and D are within normal ranges. A PaO2 level of 89 mm Hg is acceptable. An HCO3 level of 25 mEq/L falls within the normal range, suggesting adequate compensation. A pH level of 7.37 is also within the normal range, indicating the client's acid-base balance is maintained.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to discontinue the oxytocin infusion. Contractions occurring every 45 seconds indicate uterine hyperstimulation, which can pose risks to both the client and the fetus. By stopping the oxytocin infusion, the nurse can help prevent further complications. Choices B, C, and D are incorrect because increasing, decreasing, or maintaining the oxytocin infusion can exacerbate the uterine hyperstimulation and increase the risks associated with it.

Correct Answer: B

Rationale: The correct answer is B. Ileostomy stomas typically drain liquid continuously, unlike colostomies. This continuous drainage is a key characteristic that clients should understand postoperatively. Choice A is incorrect because ensuring medications are enteric-coated is not directly related to understanding ileostomy care. Choice C is incorrect as changing the pouch system every two weeks is not a general rule and may vary depending on the individual's needs. Choice D is incorrect because the stoma size can change during the healing process and clients should be informed about this possibility.

Correct Answer: B

Rationale: The correct answer is B: Wear a dosimeter badge. When caring for a client with a sealed radiation implant, the nurse should wear a dosimeter badge to monitor radiation exposure. This badge helps measure the amount of radiation the nurse is exposed to during care. Choice A is incorrect because removing dirty linens after double-bagging is not directly related to managing radiation exposure. Choice C is incorrect as there is no specific time limit on visitors mentioned in the context of a sealed radiation implant. Choice D is incorrect as there is no evidence supporting the need for family members to stay a specific distance away from the client.

Correct Answer: C

Rationale: Using perfumed toilet paper can irritate the urinary tract and increase the risk of UTI, so it should be avoided. Wearing underwear with a cotton crotch (Choice A) is a preventive measure as cotton allows for better air circulation and reduces moisture, lowering the risk of UTIs. Wiping from front to back (Choice B) helps prevent the introduction of bacteria from the anal region to the urinary tract. Urinating after intercourse (Choice D) can help flush out bacteria introduced during sexual activity, thereby reducing the risk of UTIs.

Correct Answer: C

Rationale: The correct instruction for a client prescribed with doxazosin is to rise slowly when sitting up. Doxazosin can cause orthostatic hypotension, leading to dizziness upon sudden position changes. Instructing the client to rise slowly helps prevent this side effect. Choices A, B, and D are incorrect because they are not directly related to the potential side effects or administration of doxazosin.

Correct Answer: B

Rationale: In this situation, the nurse should prioritize administering Hydromorphone (choice B), an opioid analgesic, to manage the severe pain effectively. Opioids are the first-line treatment for severe pain, especially in end-stage conditions like osteoporosis. Promethazine (choice A) is an antihistamine and antiemetic, not a potent analgesic. Ketorolac (choice C) is a nonsteroidal anti-inflammatory drug (NSAID) that may not provide sufficient pain relief in severe cases. Amitriptyline (choice D) is a tricyclic antidepressant used for neuropathic pain and depression, but it is not the first choice for managing severe pain in this scenario.

Correct Answer: A

Rationale: Using Naegele's rule, to calculate the expected delivery date, you add one year, subtract three months, and add seven days to the first day of the last menstrual period. If the last menstrual period was in October, adding one year gives October of the following year. Subtracting three months gives July, and adding seven days gives the expected delivery date of July 11th. Therefore, the correct answer is 711. Choice B (1011) is incorrect as it doesn't follow Naegele's rule calculations. Choices C (411) and D (1211) are also incorrect as they do not align with the correct application of Naegele's rule.

Correct Answer: D

Rationale: The correct answer is D because maintaining oxygen saturation of 90% is a specific, measurable short-term goal that ensures adequate oxygenation. Choice A is not a goal focused on the client's physiological status but rather on the equipment. Choice B is related to activities of daily living and does not address the respiratory distress issue. Choice C is subjective and may not reflect the actual physiological improvement in the client's condition.
