A nurse is admitting a client who has diabetic ketoacidosis. Which of the following types of continuous infusions should the nurse initiate?
0.45% saline
NPH insulin
0.9% normal saline
Glargine insulin
The Correct Answer is C
A. 0.45% saline. This is a hypotonic solution, which may be used later in diabetic ketoacidosis (DKA) management, but it is not appropriate for initial fluid resuscitation as it does not rapidly expand intravascular volume.
B. NPH insulin. NPH is an intermediate-acting insulin and is not used for continuous infusion. In DKA, rapid insulin correction is needed, typically with a short-acting insulin like regular insulin.
C. 0.9% normal saline. This isotonic fluid is the first-line choice for fluid replacement in clients with DKA. It helps restore circulating volume and correct dehydration quickly, which is a critical initial intervention.
D. Glargine insulin. Glargine is a long-acting insulin and not suitable for IV infusion. DKA requires the use of short-acting insulin (e.g., regular insulin) administered via IV infusion to correct hyperglycemia and acidosis.

Explanation
- Pain rating: Severe, intermittent abdominal pain where the child draws their knees to the chest and then returns to normal behavior is a classic symptom of intussusception. Neither Crohn’s disease nor appendicitis typically presents with this pattern, appendicitis pain is usually constant and worsening, while Crohn’s pain is chronic and non-episodic.
- Vomiting: Vomiting in intussusception is common and often non-bilious in early stages, aligning with the child's light-colored emesis. Vomiting also occurs in appendicitis, especially in the early stages. However, it is not a prominent or early symptom of Crohn’s disease unless obstruction is present.
- Stool: The presence of blood and mucus in the stool ("currant jelly stool") is strongly associated with intussusception and may also occur in Crohn’s disease during flares due to colonic inflammation. Appendicitis does not typically cause bloody or mucoid stools, making this finding inconsistent with that diagnosis.
- Temperature: A temperature of 37.4°C is within normal limits, appendicitis however may present with low grade fever. The absence of fever at this time limits its diagnostic value in this case.
- Abdominal findings: A distended abdomen with hypoactive bowel sounds and a palpable sausage-shaped mass in the right upper quadrant is highly indicative of intussusception. These findings are not characteristic of appendicitis, which usually involves RLQ pain, or Crohn’s, which rarely presents with a discrete palpable mass.
Correct Answer is []
Explanation
- Nephrotic Syndrome: The child presents with periorbital and abdominal edema, foamy dark-colored urine, significant proteinuria (24 mg/dL), hypoalbuminemia (1.4 g/dL), and hyperlipidemia (cholesterol 465 mg/dL), all of which are classic indicators of nephrotic syndrome. The elevated ESR and low sodium further support an inflammatory renal process with fluid retention.
- Chronic Kidney Disease: CKD is a long-term progressive decline in kidney function. This child shows acute findings with severe proteinuria and low albumin, consistent with nephrotic syndrome, not CKD.
- Acute Glomerulonephritis: Usually presents with hematuria (cola-colored urine), hypertension, and mild proteinuria. This client has severe proteinuria, hypoalbuminemia, and edema, which are more typical of nephrotic syndrome.
- Hemolytic Uremic Syndrome: Commonly follows a gastrointestinal illness and includes anemia, thrombocytopenia, and acute kidney injury. This child’s platelets are elevated, not low, and there's no history of diarrheal illness, making HUS unlikely.
- Encourage a low sodium diet: Sodium restriction helps manage fluid retention and edema which are key concerns in nephrotic syndrome. It also prevents worsening of ascites and periorbital swelling.
- Administer oral corticosteroids: This is the first-line treatment for idiopathic nephrotic syndrome, especially in children. Corticosteroids reduce glomerular permeability, limiting protein loss in the urine and promoting remission.
- Initiate peritoneal dialysis: Dialysis is only indicated in severe renal failure, which this child does not have. There’s no indication of uremia or electrolyte crisis, so dialysis is not appropriate at this stage.
- Intake and output: Essential for assessing fluid balance. Children with nephrotic syndrome may retain fluid or have decreased urine output, making I&O a crucial measure.
- Daily weight: This is the most accurate way to track fluid retention or loss. Daily weight is important for evaluating response to treatment, especially as edema resolves.
- Head circumference: This is monitored in infants and toddlers, especially to assess for hydrocephalus or growth delays. It is not relevant for a school-age child with kidney issues.
- HbA1C: A measure of long-term blood glucose control, used for diagnosing and managing diabetes. Has no relevance in the diagnosis or management of nephrotic syndrome.
- Urine specific gravity: While useful in initial diagnosis (and already elevated), it is not the best indicator of ongoing progress. Daily weight and I&O are more practical and reliable for assessing edema and treatment response.
