Correct Answer: A

Rationale: The correct answer is A: Intravenous administration of thyroid hormones. Myxedema coma is a severe form of hypothyroidism that necessitates immediate replacement of thyroid hormones. Administering thyroid hormones intravenously ensures rapid absorption and effectiveness in managing the condition. Choice B, oral administration of hypnotic agents, is incorrect as it does not address the primary issue of thyroid hormone deficiency in myxedema coma. Choice C, intravenous bolus of hydrocortisone, is not the appropriate treatment for myxedema coma as adrenal insufficiency is not the primary concern in this condition. Choice D, subcutaneous administration of vitamin K, is unrelated to the management of myxedema coma and does not address the underlying thyroid hormone deficiency that characterizes this condition.

Correct Answer: A

Rationale: In this critical situation with gastric rupture and impending MODS, the priority intervention should be mechanical ventilation. This client is at risk of respiratory compromise due to the severity of the condition. Platelet transfusion (Choice B) is not the priority as there is no indication of significant bleeding. Loop diuretic therapy (Choice C) and cyanocobalamin administration (Choice D) are not the immediate priorities in this scenario and would not address the urgent need for respiratory support.

Correct Answer: A

Rationale: A laceration would most likely require immediate intervention by the healthcare provider due to its deeper tissue damage, significant bleeding, and higher risk of infection compared to abrasions, contusions, and ulcerations. Lacerations often need prompt attention to control bleeding, clean the wound, and reduce the risk of infection. Abrasions are superficial wounds that usually do not require urgent attention as they tend to heal well on their own with basic wound care. Contusions are bruises that typically resolve on their own without immediate intervention. Ulcerations are open sores that may require intervention but not necessarily immediate action unless complicated by infection or other issues.

Correct Answer: D

Rationale: The most crucial instruction for the nurse to provide the client is to seek treatment for the sarcoma immediately. Ewing's sarcoma is a type of cancer that necessitates prompt and aggressive treatment for the best possible outcome. While managing pain (Choice A) and monitoring swelling (Choice B) are important, addressing the underlying sarcoma is the priority. Instructing the client to avoid weight-bearing (Choice C) is not directly related to the treatment of Ewing's sarcoma and may not be the most critical instruction at this point.

Correct Answer: A

Rationale: The correct answer is A: 'Avoid heavy lifting for at least 6 weeks.' After abdominal surgery, it is essential to avoid heavy lifting to prevent complications such as incisional hernias and support proper healing. Choice B, 'Limit fluid intake to reduce the risk of infection,' is incorrect because adequate fluid intake is necessary for wound healing and preventing dehydration. Choice C, 'Resume normal activities as soon as possible,' is incorrect as it may increase the risk of complications and delay healing. Choice D, 'Avoid driving for at least 2 weeks,' is incorrect as the restriction on driving may vary depending on the type of surgery and individual recovery.
