A nurse is reviewing the medical record for a client who has hypothyroidism and is experiencing myxedema coma. Which of the following findings should the nurse expect?

A) Place the child in a tub bath of tepid water: While tepid water can help in some situations of hyperthermia, it is not suitable for hypothermia. A more controlled and gradual rewarming method is necessary to prevent further complications such as rewarming shock.

B) Cover the child's head with a hat: Covering the child's head with a hat is an important step in rewarming because a significant amount of body heat is lost through the head. This helps in retaining body heat and stabilizing the child’s temperature.

C) Administer acetaminophen every 4 hr: Acetaminophen is typically used for reducing fever and managing pain. It is not indicated for treating hypothermia, as it does not aid in rewarming the body or addressing the underlying hypothermic condition.

D) Obtain a specimen for blood cultures: While obtaining blood cultures might be necessary if there is a suspicion of infection, it is not a primary intervention for treating hypothermia. Immediate focus should be on rewarming and stabilizing the child.

A) Evaluate the client's understanding of diabetes management: While it is important to assess the client’s understanding of diabetes management to prevent future hyperglycemic episodes, this is not the immediate priority. The client's current hyperglycemic-hyperosmolar state needs urgent intervention to stabilize their condition before educational measures can be effective.

B) Administer potassium supplements: Potassium supplementation may be necessary, especially if the client is hypokalemic, but it is not the first action. Electrolyte levels should be monitored and corrected as part of the treatment, but the initial priority is to address the severe dehydration and hyperglycemia.

C) Initiate a continuous infusion of 0.9% sodium chloride: This is the most critical first step. Clients in a hyperglycemic-hyperosmolar state are typically severely dehydrated due to osmotic diuresis. Initiating a continuous infusion of isotonic saline helps to restore intravascular volume, improve perfusion, and stabilize hemodynamics, which is essential before addressing other issues.

D) Check for improvements in the client's level of consciousness: Monitoring the client's level of consciousness is important as it provides information about their neurological status and response to treatment. However, this is a subsequent action after initiating fluid resuscitation, which directly addresses the immediate life-threatening aspects of the hyperglycemic-hyperosmolar state.
