A nurse is developing a plan of care for a client who delivered a stillborn fetus following a placental abruption. Which of the following interventions should the nurse include?

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.

A) Request return instructions in the client's own words:
Asking the client to repeat instructions in their own words is an effective strategy for ensuring understanding, especially for individuals with low health literacy. This technique, known as the "teach-back" method, allows the nurse to assess the client’s comprehension and clarify any misunderstandings.

B) Provide brochures that reflect a seventh-grade reading level:
While providing materials at a lower reading level can be helpful, it may not be sufficient for individuals with very low health literacy. It is essential to use multiple strategies, including verbal communication and interactive methods, to ensure understanding.

C) Limit teaching materials to written information:
Relying solely on written information is not advisable for clients with low health literacy. Visual aids, demonstrations, and verbal explanations should be included to enhance comprehension and retention of information.

D) Avoid repetition of information within each session:
Repetition is actually beneficial for clients with low health literacy. Repeating key information helps reinforce learning and ensures that the client retains the essential points discussed during the teaching sessions.
