An incoherent female client with a history of hypothyroidism is brought to the emergency department by the rescue squad. Physical and laboratory findings reveal hypothermia, hypoventilation, respiratory acidosis, bradycardia, hypotension, and nonpitting edema of the face and pretibial area. Knowing that these findings suggest severe hypothyroidism, Nurse Libby prepares to take emergency action to prevent the potential complication of:

Correct Answer: C

Rationale: The scenario described with hypothermia, hypoventilation, respiratory acidosis, bradycardia, hypotension, and nonpitting edema of the face and pretibial area is indicative of myxedema coma, a severe and life-threatening complication of hypothyroidism. Myxedema coma requires immediate emergency treatment to prevent further deterioration. Choice A, thyroid storm, is a complication of hyperthyroidism characterized by an increase in body temperature, heart rate, and blood pressure. Choice B, cretinism, refers to untreated congenital hypothyroidism leading to mental and physical growth retardation. Choice D, Hashimoto's thyroiditis, is an autoimmune condition leading to hypothyroidism but does not present with the acute, life-threatening symptoms described in the scenario.

Correct Answer: A

Rationale: The correct answer is 'Tetany.' Tetany is characterized by muscle twitching, tingling, and numbness, which are indicative of hypocalcemia. After a thyroidectomy, accidental removal or damage to the parathyroid glands can lead to decreased calcium levels, resulting in tetany. Choice B, 'Hemorrhage,' is incorrect as it typically presents with symptoms such as sudden swelling, increased pain, or drop in blood pressure. Choice C, 'Thyroid storm,' is incorrect as it involves a sudden exacerbation of hyperthyroidism, leading to symptoms like fever, tachycardia, and confusion. Choice D, 'Laryngeal nerve damage,' is incorrect as it would manifest with voice changes, difficulty swallowing, or respiratory distress, not the symptoms described in the scenario.

Correct Answer: B

Rationale: The correct answer is B. Acarbose (Precose) is an alpha-glucosidase inhibitor that works by slowing carbohydrate absorption in the intestine, not by stimulating insulin release. Therefore, the client would need additional teaching if they state that the drug makes their pancreas release more insulin (Choice B). Choices A, C, and D are incorrect. Choice A is incorrect because during hypoglycemia, it is recommended to consume glucose or dextrose to rapidly raise blood sugar levels. Choice C is incorrect because insulin therapy may still be needed in some cases, even when taking acarbose. Choice D is incorrect because acarbose should be taken at the start of a meal to help reduce postprandial blood glucose levels.

Correct Answer: D

Rationale: Serum osmolarity is the most important laboratory test for confirming hyperosmolar hyperglycemic nonketotic syndrome (HHNS). HHNS is characterized by severe hyperglycemia and dehydration without ketoacidosis. Elevated serum osmolarity indicates increased solute concentration in the blood, which is a hallmark of HHNS. Serum potassium level (Choice A) is important in conditions like diabetic ketoacidosis rather than HHNS. Serum sodium level (Choice B) may be affected in HHNS but is not the primary test for confirming the disorder. Arterial blood gas (ABG) values (Choice C) are more useful in assessing acid-base status, which is not the primary concern in HHNS.

Correct Answer: D

Rationale: Gluconeogenesis is a process where the body synthesizes glucose from non-carbohydrate sources to maintain blood glucose levels. Documenting weight changes due to fatty acid mobilization is important as it can impact the patient's metabolic status. Evaluating the patient's sensitivity to low room temperatures because of decreased adipose tissue insulation is crucial to prevent hypothermia. Protecting the patient from sources of infection due to decreased cellular protein deposits is essential to prevent complications. Therefore, all the options are relevant considerations in managing a patient undergoing gluconeogenesis, making option D the correct answer.
