question
A client with diabetes mellitus has a prescription for 5 units of U-100 regular insulin and 25 units of U-100 isophane insulin suspension (NPH) to be taken before breakfast. At about 4:30 p.m., the client experiences headache, sweating, tremor, pallor, and nervousness. What is the most probable cause of these signs and symptoms? A. Serum glucose level of 450 mg/dl B. Serum glucose level of 52 mg/dl C. Serum calcium level of 8.9 mg/dl D. Serum calcium level of 10.2 mg/dl
answer
B Headache, sweating, tremor, pallor, and nervousness typically result from hypoglycemia, an insulin reaction in which serum glucose level drops below 70 mg/dl. Hypoglycemia may occur 4 to 18 hours after administration of isophane insulin suspension or insulin zinc suspension (Lente), which are intermediate-acting insulins. Although hypoglycemia may occur at any time, it usually precedes meals. Hyperglycemia, in which serum glucose level is above 180 mg/dl, causes such early manifestations as fatigue, malaise, drowsiness, polyuria, and polydipsia.

question
A 78-year-old patient with type 2 diabetes is brought to the emergency department by his daughter. The patient is found to have a blood glucose level of 623 mg/dL. The patient's daughter reports that the patient recently had a gastrointestinal virus and has been confused for the last 3 hours. A diagnosis of hyperglycemic hyperosmolar nonketotic syndrome (HHNS) is made. What nursing action would be the priority? A. Administering antihypertensive medications B.Administering sodium bicarbonate intravenously for low bicarbonate levels C. Reversing acidosis by administering insulin D. Replacing fluids and electrolytes
answer
D. The overall approach to HHNS includes fluid replacement, correction of electrolyte imbalances, and insulin administration. Insulin administration plays a less important role in the treatment of HHNS because it is not needed for reversal of acidosis, as in diabetic ketoacidosis (DKA). Sodium bicarbonate is not administered to patients with HHNS, as their plasma bicarbonate level is usually normal. Also, antihypertensive medications are not indicated, as hypotension generally accompanies HHNS, due to dehydration
question
Which is the best nursing explanation for the symptom of polyuria in a client with diabetes mellitus? A. High sugar pulls fluid into the bloodstream, which results in more urine production. B. With diabetes, drinking more results in more urine production. C. Increased ketones in the urine promote the manufacturing of more urine. D. The body's requirement for fuel drives the production of urine.
answer
A
question
Which is the primary reason for encouraging injection site rotation in an insulin dependent diabetic? A Promote absorption. B Avoid infection. C. Minimize discomfort. D Prevent muscle destruction.
answer
A Subcutaneous injection sites require rotation to avoid breakdown and/or buildup of subcutaneous fat, either of which can interfere with insulin absorption in the tissue. Infection and discomfort are risks involved with injection site but not the primary reason for rotation of sites. Insulin is not injected into the muscle.
question
A child is brought into the emergency department with vomiting, drowsiness, and blowing respirations. The father reports that the symptoms have been progressing throughout the day.

Begin fluid replacements. D. Administer prescribed dose of insulin.
answer
C Management of DKA is aimed at correcting dehydration, electrolyte loss, and acidosis before correcting the hyperglycemia with insulin
