Body System, Finding
General,
Client is brought to the emergency department due to nausea, vomiting, and abdominal pain that began 24 hr
ago. Client has type 1 diabetes mellitus and usually takes insulin. Parents state that the client was at an
overnight camp for the past 4 days and are unsure of how much insulin the client has been taking.
Neurological,
Client is lethargic but arousable to voice. The pupils are equal, round, and reactive to light and accommodation.
Integumentary,
Mucous membranes are dry, skin turgor is poor.
Pulmonary,
Vital signs are RR 36 and SpOz 95% on room air. Lung sounds are clear to auscultation. Deep respirations and a
fruity odor on the breath are noted.
Cardiovascular,
Vital signs are T 98.4 F (36.9 C), P 110, and BP 98/58. Pulses are 3+ on all extremities, and capillary refill time is
4 sec.
Gastrointestinal Normoactive bowel sounds are heard in all 4 quadrants; the abdomen is nontender.
Genitourinary,
Client voided dark yellow urine.
Endocrine,
Client is prescribed levothyroxine daily for hypothyroidism and has missed one dose of levothyroxine.
Psychosocial,
Parents state that the client has been sad and slightly withdrawn for the past 2 weeks after ending a romantic relationship.

Drag words from the choices below to fill in the blank/blanks. The nurse understands that treatment for diabetic ketoacidosis is resolved when the-----------,--------, and ----------
Correct Answer: B,D,E
Rationale: Diabetic ketoacidosis (DKA) causes anion gap metabolic acidosis generated by the ketoacid anions and beta-hydroxybutyrate. Anion gap is
calculated based on electrolyte levels to determine the balance of cations and anions (le, acids and bases).
IV insulin infusion may be discontinued on resolution of acidosis and ketosis, which generally occurs with a blood glucose level of <200
mg/dL (11.1 mmol/L). However, measurement of serum glucose alone is inappropriate for monitoring the response to treatment because
ketosis and acidemia may still be present. With fluid resuscitation and correction of hyperosmolality and hyperglycemia, ketoacids disappear
and the anion gap and arterial blood gas results normalize, pointing to resolution of metabolic acidosis and ketonuria ie, ketones in
urine.
