After an increase in the number of suicides in a community, the nurse is developing a class for adolescents about mental health.

Which type of activity should the nurse include in the teaching?

Rationalizing the Priority
1. Airway/Breathing (D):
The "A" and "B" of the ABCs take precedence. In myxedema coma, hypoventilation is a primary concern. The client may experience respiratory muscle weakness or a decreased drive to breathe, leading to CO₂ retention and respiratory failure. Assessing the rate, depth, and effort of breathing is the absolute first step.

2. Circulation (B):
Once the airway is confirmed, you assess the "C" (Circulation). Myxedema coma causes severe bradycardia and decreased cardiac output, which leads to hypotension. Assessing blood pressure tells the nurse if the client is in cardiogenic shock.

3. Vital Signs/Metabolic State (C):
Hypothermia is a hallmark sign of myxedema coma (temperatures can often drop below 95°F or 35°C). While critical, it is addressed after ensuring the heart is pumping and the lungs are moving air. Monitoring temperature is vital because rapid rewarming can actually cause vasodilation and worsen shock.

4. Focused Physical Assessment (A):
Palpating for edema is an important part of a head-to-toe assessment for hypothyroidism (non-pitting mucinous edema is common), but it is not a life-saving intervention. It is a secondary assessment compared to the vital signs and respiratory status.

Choice A rationale:

Correcting electrolytes that are out of normal range is a crucial goal of therapy for this client. In diabetic ketoacidosis (DKA), the body’s cells are unable to use glucose for energy due to a lack of insulin. This leads to the breakdown of fat for energy, producing ketones as a by-product. Ketones are acidic and can cause the blood’s pH to decrease, leading to metabolic acidosis. This process also leads to an increased production and excretion of electrolytes such as potassium and sodium. Therefore, correcting these electrolyte imbalances is a key goal of therapy.

Choice B rationale:

While promoting oxygenation to tissues is generally important in critical care, it is not a specific goal in the management of DKA. The primary issues in DKA are metabolic in nature, including hyperglycemia, ketosis, and acidosis.

Choice C rationale:

Preventing hyperventilation is not a specific goal in the management of DKA. Hyperventilation in DKA is a compensatory mechanism for metabolic acidosis (Kussmaul breathing). The body tries to expel more carbon dioxide to reduce the acidity of the blood.

Choice D rationale:

Reversing dehydration is another important goal of therapy for this client. In DKA, high blood glucose levels lead to osmotic diuresis, where water is drawn into the urine from the blood, leading to dehydration. This can cause hypotension and reduced tissue perfusion. Therefore, reversing dehydration through fluid replacement is a key part of treatment.

Choice E rationale:

Replacing insulin is a fundamental goal of therapy for this client. Insulin deficiency is the primary cause of DKA. Insulin allows glucose to enter cells where it can be used for energy, preventing the breakdown of fat for energy and the subsequent production of ketones.

Choice F rationale:

Providing respiratory support may be necessary in severe cases of DKA where the patient’s compensatory respiratory efforts are insufficient to maintain adequate gas exchange. However, it is not one of the primary goals of therapy in DKA management.
