Which of the following is an age-related change that may affect diabetes and its management?
Decreased renal function -Decreased renal function affects the management of diabetes. With decreasing renal function, it takes longer for oral hypoglycemic agents to be excreted by the kidneys and changes in insulin clearance occur with decreased renal function. Other age-related changes that may affect diabetes and its management include hypertension, decreased bowel motility, and decreased thirst.
A client with status asthmaticus requires endotracheal intubation and mechanical ventilation. Twenty-four hours after intubation, the client is started on the insulin infusion protocol. The nurse must monitor the client's blood glucose levels hourly and watch for which early signs and symptoms associated with hypoglycemia?
Sweating, tremors, and tachycardia -Sweating, tremors, and tachycardia, thirst, and anxiety are early signs of hypoglycemia.
A client with diabetes mellitus must learn how to self-administer insulin. The physician has ordered 10 units of U-100 regular insulin and 35 units of U-100 isophane insulin suspension (NPH) to be taken before breakfast. When teaching the client how to select and rotate insulin injection sites, the nurse should provide which instruction?
"Rotate injection sites within the same anatomic region, not among different regions." -The nurse should instruct the client to rotate injection sites within the same anatomic region. Rotating sites among different regions may cause excessive day-to-day variations in the blood glucose level; also, insulin absorption differs from one region to the next. Insulin should be injected only into healthy tissue lacking large blood vessels, nerves, or scar tissue or other deviations. Injecting insulin into areas of hypertrophy may delay absorption.
A nurse is caring for a client with diabetes mellitus. The client has a blood glucose level of 40 mg/dL. Which of the following rapidly absorbed carbohydrate would be most effective?
1/2 cup fruit juice or regular soft drink -In a client with hypoglycemia, the nurse uses the rule of 15: Give 15 g of rapidly absorbed carbohydrate, wait 15 minutes, recheck the blood sugar, and administer another 15 g of glucose if the blood sugar is not above 70 mg/dL. One-half cup fruit juice or regular soft drink is equivalent to the recommended 15 g of rapidly absorbed carbohydrate.
Which of the following is true regarding gestational diabetes?
A glucose challenge test should be performed between 24 to 28 weeks. -It occurs in 2 to 5% of all pregnancies. Onset is usually in the second or third trimester.
A client is admitted with hyperosmolar hyperglycemic nonketotic syndrome (HHNS). Which laboratory finding should the nurse expect in this client?
Blood glucose level 1,100 mg/dl -HHNS occurs most frequently in older clients. It can occur in clients with either type 1 or type 2 diabetes mellitus but occurs most commonly in those with type 2. The blood glucose level rises to above 600 mg/dl in response to illness or infection. As the blood glucose level rises, the body attempts to rid itself of the excess glucose by producing urine. Initially, the client produces large quantities of urine. If fluid intake isn't increased at this time, the client becomes dehydrated, causing BUN levels to rise.
The diabetic client asks the nurse why shoes and socks are removed at each office visit. Which assessment finding is most significant in determining the protocol for inspection of feet?
Sensory neuropathy -Neuropathy results from poor glucose control and decreased circulation to nerve tissues. Neuropathy involving sensory nerves located in the periphery can lead to lack of sensitivity, which increases the potential for soft tissue injury without client awareness. The feet are inspected on each visit to insure no injury or pressure has occurred
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?
Serum glucose level of 52 mg/dl -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.
A male client, aged 42 years, is diagnosed with diabetes mellitus. He visits the gym regularly and is a vegetarian. Which of the following factors is important when assessing the client?
The client's consumption of carbohydrates
A nurse is caring for a diabetic patient with a diagnosis of nephropathy. What would the nurse expect the urinalysis report to indicate?
albumin -Albumin is one of the most important blood proteins that leak into the urine. Although small amounts may leak undetected for years, its leakage into the urine is among the earliest signs that can be detected. Clinical nephropathy eventually develops in more than 85% of people with microalbuminuria but in fewer than 5% of people without microalbuminuria (Chart 51-10). The urine should be checked annually for the presence of microalbumin.
