Which chemical buffers excessive acetoacetic acid? 1. Potassium 2. Sodium bicarbonate 3. Carbon dioxide 4. Sodium chloride
2. Sodium bicarbonate Sodium bicarbonate is a base and one of the major buffers in the body. Potassium, a cation, is not a buffer; only a base can buffer an acid. Carbon dioxide is carried in aqueous solution as carbonic acid (H 2CO 3); an acid does not buffer another acid. Sodium chloride is not a buffer; it is a salt.
Which hormone would the nurse identify as inhibiting insulin and glucagon secretion? 1. Amylin 2. Somatostatin 3. Triiodothyronine (T 3) 4. Pancreatic polypeptide
2. Somatostatin Somatostatin is a hormone that inhibits insulin and glucagon secretion, as well as growth hormone
A client newly diagnosed with type 1 diabetes asks why it is necessary to exercise on a regular basis. Which response is accurate? 1. "Exercise decreases insulin sensitivity." 2. "It stimulates glucagon production." 3. "Exercise improves the cellular uptake of glucose." 4. "It reduces metabolic requirements for glucose."
3. "Exercise improves the cellular uptake of glucose." Exercise increases the metabolic rate, and glucose is needed for cellular metabolism; therefore, excess glucose is consumed during exercise. Regular vigorous exercise increases cell sensitivity to insulin. Glucagon action raises blood glucose but does not affect cell uptake or use of glucose. Cellular requirements for glucose increase with exercise.
An adolescent who has just been found to have type 1 diabetes asks the nurse about exercise. Which is the best response by the nurse? 1. "Exercise should be restricted." 2. "Exercise will increase blood glucose." 3. "Extra snacks are needed before exercise." 4. "Extra insulin is required during exercise.
3. "Extra snacks are needed before exercise."
Between which weeks of gestation would a client with type 1 diabetes expect to increase her insulin dosage? 1. 10th and 12th weeks of gestation 2. 18th and 22nd weeks of gestation 3. 24th and 28th weeks of gestation 4. 36th and 40th weeks of gestation
3. 24th and 28th weeks of gestation At the end of the second trimester and the beginning of the third trimester, insulin needs increase because of an increase in maternal resistance to insulin. During the earlier part of pregnancy, fetal demands for maternal glucose may cause a tendency toward hypoglycemia. During the last weeks of pregnancy, maternal resistance to insulin decreases, and insulin needs decrease accordingly.
While obtaining the client's health history, which factor would the nurse identify that predisposes the client to type 2 diabetes? 1. Having diabetes insipidus 2. Eating low-cholesterol foods 3. Being 20 pounds (9 kg) overweight 4. Drinking a daily alcoholic beverage
3. Being 20 pounds (9 kg) overweight Excessive body weight is a known predisposing factor to type 2 diabetes; the exact relationship is unknown. Diabetes insipidus is caused by too little antidiuretic hormone (ADH) and has no relationship to type 2 diabetes. High-cholesterol diets and atherosclerotic heart disease are associated with type 2 diabetes. Alcohol intake is not known to predispose a person to type 2 diabetes.
The health care provider prescribes an oral hypoglycemic medication for the client with type 2 diabetes. Which statement will the nurse need to consider when developing the teaching plan? 1. Oral hypoglycemics work by decreasing absorption of carbohydrates. 2. Oral hypoglycemics work by stimulating the pancreas to produce insulin. 3. Clients taking oral hypoglycemics may subconsciously relax dietary rules to gain a sense of control. 4. Serious adverse effects are not a problem for oral hypoglycemic
3. Clients taking oral hypoglycemics may subconsciously relax dietary rules to gain a sense of control. Taking a tablet may give the client a false sense that the disease is under control, and this can lead to dietary indiscretions. Some oral hypoglycemics work by stimulating the pancreas to produce insulin, others work by decreasing carbohydrate absorption, and others work in a variety of other ways; therefore teaching should be specific to the medication prescribed. Oral hypoglycemic medications can have serious adverse effects.
An insulin pump is instituted for a client with type 1 diabetes. The nurse plans discharge instructions. Which short-term goal is the priority for this client? 1. Plan daily intake incorporating diabetic diet guidelines. 2. Demonstrate proper subcutaneous insulin injection technique. 3. Demonstrate correct use of the insulin pump. 4. List three self-care activities that help control the diabetes.
3. Demonstrate correct use of the insulin pump.

3. Diabetic acidosis
Why is 15 g of a simple sugar administered when a client with diabetes experiences hypoglycemia? 1. Inhibits glycogenesis 2. Stimulates release of insulin 3. Increases blood glucose levels 4. Provides more storage of glucose
3. Increases blood glucose levels
Glucose transportation into the cells through cell membranes takes place in which order? 1. Transformation of proinsulin into active insulin 2. Attachment of insulin to receptors 3. Secretion of proinsulin by beta cells 4. Storage of proinsulin in the pancreas
3. Secretion of proinsulin by beta cells 4. Storage of proinsulin in the pancreas 1. Transformation of proinsulin into active insulin 2. Attachment of insulin to receptors Proinsulin is a prohormone that is secreted by beta cells and is stored in the beta cells of islets of Langerhans of the pancreas. Active insulin is a protein made up of 51 amino acids; it is produced when C-peptide is removed from the proinsulin. Insulin attaches to receptors present on the target tissues, such as adipose tissue or muscle, where the promotion of glucose transport into the cells through cell membranes occurs.
When teaching a client with type 2 diabetes, which statement by the nurse reflects accurate information about preparing for a serum glucose test? 1. "Eat your usual breakfast." 2. "Have clear liquids for breakfast." 3. "Take your medication before the test." 4. "Do not ingest anything before the test."
4. "Do not ingest anything before the test."
A client with type 2 diabetes takes one glyburide tablet daily. The client asks whether an extra tablet should be taken before exercise. Which response will the nurse provide? 1. "You will need to decrease how much you are exercising." 2. "An extra pill will help your body use glucose when exercising." 3. "The amount of medication you need to take is not related to exercising." 4. "Do not take an extra pill because you may become hypoglycemic when exercising."
4. "Do not take an extra pill because you may become hypoglycemic when exercising."

4. Hypoglycemia
A full-term infant who is large for gestational age (LGA) should be monitored for which risk? 1. Hypotension 2. Hypothermia 3. Hypocalcemia 4. Hypoglycemia
4. Hypoglycemia Infants that are LGA are considered at risk for hypoglycemia, and their glucose should be monitored following a protocol. LGA infants are not at an increased risk for hypotension, hypothermia, or hypocalcemia.
A client with type 1 diabetes receives 30 units of neutral protamine Hagedorn (NPH) insulin at 7:00 AM. At 3:30 PM, the client becomes diaphoretic, weak, and pale. With which condition would the nurse determine that these physiological responses are associated? 1. Diabetic coma 2. Hyperosmolar hyperglycemic nonketotic syndrome 3. Diabetic ketoacidosis 4. Hypoglycemic reaction
4. Hypoglycemic reaction These are sympathetic nervous system responses to hypoglycemia;
In which parts of the kidney are glucose and amino acids reabsorbed? 1. Distal tubule 2. Loop of Henle 3. Collecting duct 4. Proximal tubule
4. Proximal tubule Glucose, amino acids, electrolytes, and bicarbonate are reabsorbed in the proximal tubule.
Which mechanism of action explains how glyburide decreases serum glucose levels? 1. Stimulates the pancreas to produce insulin 2. Accelerates the liver's release of stored glycogen 3. Increases glucose transport across the cell membrane 4. Decreases absorption of glucose from the gastrointestinal system
1. Stimulates the pancreas to produce insulin
A client with type 1 diabetes asks what causes several brown spots on the skin. What would be the best response by the nurse? 1. "The brown spots reflect the accumulation of blood fats in the skin; they should disappear." 2. "Those spots indicate a high glucose content in the skin that may get infected if left untreated." 3. "They are the result of diseased small vessels in the shins and may spread if not treated soon." 4. "Those brown spots result from small blood vessel damage; the blood contains iron, which leaves a brown spot."
4. "Those brown spots result from small blood vessel damage; the blood contains iron, which leaves a brown spot." Those brown spots result from small blood vessel damage; the blood contains iron, which leaves a brown spot" is an accurate explanation for the client's concern; brown spots are caused by the deposit of hemosiderin in the tissue.
