A home health nurse is teaching a parent about diet recommendations for a toddler who has Down syndrome and failure to thrive. Which of the following statements should indicate to the nurse that the parent understands the teaching?

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) Reports intolerance to heat: Intolerance to heat is more commonly associated with conditions like hyperthyroidism rather than iron-deficiency anemia. Individuals with iron-deficiency anemia often experience fatigue and cold intolerance due to decreased oxygen-carrying capacity of the blood.

B) Develops bradycardia after eating: Bradycardia (slow heart rate) is not typically associated with iron-deficiency anemia. Anemia usually causes an increased heart rate (tachycardia) as the body tries to compensate for reduced oxygen delivery.

C) Has a friction rub on auscultation: A friction rub is a sound heard on auscultation associated with pericarditis, an inflammation of the pericardium, and is not a typical finding in iron-deficiency anemia. Anemia primarily affects the blood and does not usually cause inflammation of the heart lining.

D) Displays dyspnea while walking: Dyspnea, or shortness of breath, is a common symptom of iron-deficiency anemia, particularly with exertion. This occurs because the reduced hemoglobin levels result in decreased oxygen delivery to tissues, making physical activities more challenging and causing breathlessness.
