Maintaining adequate fluid and replacing vasopressin are the main objectives in treating diabetes insipidus.

Option A: Diabetes is a chronic condition associated with abnormally high levels of sugar (glucose) in the blood. Insulin produced by the pancreas lowers blood glucose.
Option C: Diabetic ketoacidosis is a result of severe insulin insufficiency.
Option D: An excess of antidiuretic hormone leads to SIADH, causing the patient to retain fluid.

During periods of infection or illness, patients with Type 1 diabetes may need even more insulin to compensate for increased blood glucose levels.

Option A: Changes should be applied to the patient’s daily routine to avoid complications from infection.
Option B: Less insulin could lead to hyperglycemia.
Option D: Oral diabetic agents may not be enough to decrease the blood glucose.

A decreased hematocrit level is a sign of hematoma, a delayed complication of abdominal and vaginal hysterectomy.

Option B: Symptoms of hypovolemia include increased hematocrit and hemoglobin values.
Option C: Infection manifests with fever and high WBC count.
Option D: Symptoms of a PE include dyspnea, chest pain, cough, hemoptysis, restlessness, and signs of shock.

Lactated Ringer’s solution replaces lost sodium and corrects metabolic acidosis, both of which commonly occur following a burn.

Option A: Albumin is used as an adjunct therapy, not a primary fluid replacement.
Option B: Dextrose isn’t given to burn patients during the first 24 hours because it can cause pseudodiabetes.
Option D: The patient is hyperkalemic from the potassium shift from the intracellular space to the plasma, so potassium would be detrimental.

Rolling a swab from the center outward is the right way to obtain a culture specimen from a wound.

Option A: Irrigating the wound washes away drainage, debris, and many of the colonizing or infecting microorganisms.
Option B: The outside of the wound and the dressing may be colonized with microorganisms that haven’t affected the wound, so specimens from these sites could give inaccurate results.
Option D: The dressing is considered contaminated and should not be used for collection of specimens.
