"1. A patient with newly diagnosed type 2 diabetes mellitus asks the nurse what ""type 2"" means in
relation to diabetes. The nurse explains to the patient that type 2 diabetes differs from type 1 diabetes
primarily in that with type 2 diabetes
a. the pt is totally dependent on an outside source of insulin
b. there is a decreased insulin secretion and cellular resistance to insulin that is produced
c. the immune system destroys the pancreatic insulin-producing cells
d. the insulin precursor that is secreted by the pancreas is not activated by the liver
Answer B - Rationale: In type 2 diabetes, the pancreas produces insulin, but the insulin is insufficient
for the body's needs or the cells do not respond to the insulin appropriately. The other information
describes the physiology of type 1 diabetes
The benefits of using an insulin pump include all of the following except: "a. By continuously providing
insulin they eliminate the need for injections of insulin
b. They simplify management of blood sugar and often improve A1C
c. They enable exercise without compensatory carbohydrate consumption
d. They help with weight loss
D: Using an insulin pump has many advantages, including fewer dramatic swings in blood glucose
levels, increased flexibility about diet, and improved accuracy of insulin doses and delivery; however,
the use of an insulin pump has been associated with weight gain.
A 54-year-old patient admitted with type 2 diabetes, asks the nurse what "type 2" means. Which of the
following is the most appropriate response by the nurse?
"1. ""With type 2 diabetes, the body of the pancreas becomes inflamed."
2. "With type 2 diabetes, insulin secretion is decreased and insulin resistance is increased."
3. "With type 2 diabetes, the patient is totally dependent on an outside source of insulin."
4. "With type 2 diabetes, the body produces autoantibodies that destroy b-cells in the pancreas.""
"Right Answer: 2
Rationale: In type 2 diabetes mellitus, the secretion of insulin by the pancreas is reduced and/or the
cells of the body become resistant to insulin"
"A client is admitted to the hospital with signs and symptoms of diabetes mellitus. Which findings is the
nurse most likely to observe in this client? Select all that apply:
"1. Excessive thirst
2. Weight gain
3. Constipation
4. Excessive hunger
5. Urine retention
6. Frequent, high-volume urination
1, 4, 6 Rationale: Classic signs of diabetes mellitus include polydipsia (excessive thirst),
polyphagia (excessive hunger), and polyuria (excessive urination). Because the body is starving from
the lack of glucose the cells are using for energy, the client has weight loss, not weight gain. Clients
with diabetes mellitus usually don't present with constipation. Urine retention is only a problem is the
patient has another renal-related condition.
A client is brought to the emergency department in an unresponsive state, and a diagnosis of
hyperglycemic hyperosmolar nonketotic syndrome is made. The nurse would immediately prepare to
initiate which of the following anticipated physician's prescriptions?
1. Endotracheal intubation
2. 100 units of NPH insulin
3. Intravenous infusion of normal saline
4. Intravenous infusion of sodium bicarbonate
CORRECT ANSWER: 3. Intravenous infusion of normal saline Rationale: The primary goal of treatment
is hyperglycemic hyperosmolar nonketotic syndrome (HHNS) is to rehydrate the client to restore the
fluid volume and to correct electrolyte deficiency. Intravenous fluid replacement is similar to that
administered in diabetic keto acidosis (DKA) and begins with IV infusion of normal saline. Regular
insulin, not NPH insulin, would be administered. The use of sodium bicarbonate to correct acidosis is
avoided because it can precipitate a further drop in serum potassium levels. Intubation and
mechanical ventilation are not required to treat HHNS.
"A client is taking Humulin NPH insulin daily every morning. The nurse instructs the client that the most
likely time for a hypoglycemic reaction to occur is:
A) 2-4 hours after administration
B) 4-12 hours after administration
C) 16-18 hours after administration
D) 18-24 hours after administration
B: Rationale: Humulin is an intermediate acting insulin. The onset of action is 1.5 hours, it peaks in 412
hours,
and
its
duration
is
24
hours.
Hypoglycemic
reactions
to

"A client who is started on metformin and glyburide would have initially presented with which
symptoms?
"a. Polydipsia, polyuria, and weight loss
b. weight gain, tiredness, & bradycardia
c. irritability, diaphoresis, and tachycardia
d. diarrhea, abdominal pain, and weight loss
"a. Polydipsia, polyuria, and weight loss". Symptoms of hyperglycemia include polydipsia, polyuria,
and weight loss. Metformin and sulfonylureas are commonly ordered medications.
Weight gain, tiredness, and bradycardia are symptoms of hypothyroidism.
Irritability, diaphoresis, and tachycardia are symptoms of hypoglycemia.
Symptoms of Crohn's disease include diarrhea, abdominal pain, and weight loss."
A client with diabetes mellitus demonstrates acute anxiety when first admitted for the treatment of
hyperglycemia. The most appropriate intervention to decrease the client's anxiety would be to
1. administer a sedative
2. make sure the client knows all the correct medical terms to understand what is happening
3. ignore the signs and symptoms of anxiety so that they will soon disappear
4. convey empathy, trust, and respect toward the client
4. The most appropriate intervention is to address the client’s feelings related to the anxiety
A client with diabetes melllitus has a blood glucose of 644mg/dl. The nurse interprets that this client is
most at risk of developing which type of acid base imbalance?
"A. Metabolic acidosis
B. Metabolic alkalosis
C. Respiratory Acidosis
D. Respiratory Alkalosis"
"Correct Answer: A, Metabolic Acidosis
Rationale: DM can lead to metabolic acidosis. When the body does not have sufficient circulating
insulin, the blood glucose level rises. At the same time, the cells of the body use all available glucose.
The body then breaks down glycogen and fat for fuel. The by-products of fat metabolism are acidotic
and can lead to the condition known as diabetic ketoacidosis."
A client with DKA is being treated in the ED. What would the nurse suspect?
1. Comatose state
2. Decreased Urine Output
3. Increased respirations and an increase in pH.
4. Elevated blood glucose level and low plasma bicarbonate level.
Correct Answer: 4
Rationale: In DKA the arteriole pH is lower than 7.35, plasma bicarbonate is lower than 15 mEq/L, the
blood glucose is higher than 250, and ketones are present in the blood and urine. The client would be
experiencing polyuria and Kussmauls respirations would be present. A comatose state may occur if
DKA is not treated.
A client with type I diabetes is placed on an insulin pump. The most appropriate short-term goal when
teaching this client to control the diabetes is:
"1) adhere to the medical regimen
2) remain normoglycemic for 3 weeks
3) demonstrate the correct use of the administration equipment.
4) list 3 self care activities that are necessary to control the diabetes"
3.) is correct
"1) this is not a short-term goal
2) this is measurable, but it's a long-term goal
3) this is a short-term goal, client oriented, necessary for the client to control the diabetes, and
measurable when the client performs a return demonstration for the nurse
4) although this is measurable and a short-term goal, it is not the one with the greatest priority when
a client has an insulin pump that must be mastered before discharge"
"A diabetic patient has a serum glucose level of 824 mg/dL (45.7 mmol/L) and is unresponsive. Following
assessment of the patient, the nurse suspects diabetic ketoacidosis rather than hyperosmolar
hyperglycemic syndrome based on the finding of
"a. polyuria
b. severe dehydration
c. rapid, deep respirations )
d. decreased serum potassium"
C is correct, Signs and symptoms of DKA include manifestations of dehydration such as poor skin
turgor, dry mucous membranes, tachycardia, and orthostatic hypotension. Early symptoms may
include lethargy and weakness. As the patient becomes severely dehydrated, the skin becomes dry
and loose, and the eyeballs become soft and sunken. Abdominal pain is another symptom of DKA that
may be accompanied by anorexia and vomiting. Kussmaul respirations (i.e., rapid, deep breathing
associated with dyspnea) are the body’s attempt to reverse metabolic acidosis through the exhalation
of excess carbon dioxide. Acetone is identified on the breath as a sweet, fruity odor. Laboratory
findings include a blood glucose level greater than 250 mg/dL, arterial blood pH less than 7.30, serum
bicarbonate level less than 15 mEq/L, and moderate to large ketone levels in the urine or blood
ketones.
"A frail elderly patient with a diagnosis of type 2 diabetes mellitus has been ill with pneumonia. The
client’s intake has been very poor, and she is admitted to the hospital for observation and management
as needed. What is the most likely problem with this patient?
"A. Insulin resistance has developed.
B. Diabetic ketoacidosis is occurring.
C. Hypoglycemia unawareness is developing.
D. Hyperglycemic hyperosmolar non-ketotic coma.
D. Illness, especially with the frail elderly patient whose appetite is poor, can result in dehydration
and HHNC. Insulin resistance is indicated by a daily insulin requirement of 200 units or more. Diabetic
ketoacidosis, an acute metabolic condition, usually is caused by absent or markedly decreased
amounts of insulin.
A home health nurse is at the home of a client with diabetes and arthritis. The client has difficulty
drawing up insulin. It would be most appropriate for the nurse to refer the client to:
"A) A social worker from the local hospital
B) An occupational therapist from the community center
C) A physical therapist from the rehabilitation agency
D) Another client with diabetes mellitus and takes insulin"
B) An occupational therapist can assist a client to improve the fine motor skills needed to prepare an
insulin injection.
A nurse is caring for a client with type 1 diabetes mellitus. which client complaint would alert the nurse
to the presence of a possible hypoglycemic reaction?
"1. Tremors
2. Anorexia
3. Hot, dry skin
4. Muscle cramps
1) tremors decreased blood glucose levels produce autonomic nervous system symptoms, which are
manifested classically as nervousness, irritability, and tremors. option 3 is more likely for
hyperglycemia, and options 2 and 4 are unrelated to the signs of hypoglycemia.
"A nurse is caring for a client admitted to the emergency department with diabetic ketoacidosis (DKA). In
the acute phase, the priority nursing action is to prepare to:
"A. Correct the acidosis
B. Administer 5% dextrose intravenously
C. Administer regular insulin intravenously
D. Apply a monitor for an electrocardiogram."
C. Administer regular insulin inraVenously Lack (absolute or relative) of insulin is the primary cause of
DKA. Treatment consists of insulin administration (regular insulin), intravenous fluid administration
(normal saline initially), and potassium replacement, followed by correcting acidosis. Applying an
electrocardiogram monitor is not a priority action.
A nurse is caring for a client with type 1 diabetes mellitus. Which client complaint would alert the nurse
to the presence of a possible hypoglycemic reaction ?
A. Tremors
B. Anorexia
C. Hot, Dry skin
D. Muscle cramps
Correct Answer A Decreased blood glucose levels produce autonomic nervous system symptoms,
which are manifested classically as nervousness, irritability, and tremors. Option C is more likely to
occur with hyperglycemia. Options B and D are unrelated to the signs of hyperglycemia
a nurse is interviewing a client with type 2 diabetes mellitus. which statement by the client indicated an
understanding of the treatment for this disorder?
"1. ""i take oral insulin instead of shots""
2. ""by taking these medications I am able to eat more""
3. ""when I become ill, I need to increase the number of pills I take""
4. ""the medications I'm taking help release the insulin I already make""
4.)Clients with type 2 diabetes mellitus have decreased or impaired insulin secretion. Oral
hypoglycemic agents are given to these clients to facilitate glucose uptake. Insulin injections may be
given during times of stress-induced hyperglycemia. Oral insulin is not available because of the
breakdown of the insulin by digestion. Options 1, 2 and 3 are incorrect
A nurse is preparing a plan of care for a client with diabetes mellitus who has hyperglycemia. The priority
nursing diagnosis would be:
1. Deficient knowledge
2. Deficient fluid volume
3. Compromised family coping
4. Imbalanced nutrition less than body requirements
2) deficient fluid volume An increased blood glucose level will cause the kidneys to excrete the glucose
in the urine. This glucose is accompanied by fluids and electrolytes, causing an osmotic diuresis
leading to dehydration. This fluid loss must be replaced when it becomes severe.
A nurse is preparing a teaching plan for a client with diabetes Mellitus regarding proper foot care. Which
instruction is included in the plan?
1. Soak feet in hot water
2. apply a moisturizing lotion to dry feet but not between the toes
3. Always have a podiatrist cut your toenails, never cut them yourself
4. avoid using mild soap on the feet
2. The client is instructed to use a moisturizing lotion on the feet and to avoid applying the lotion
between the toes.
"A nurse performs a physical assessment on a client with type 2 diabetes mellitus. Findings include a
fasting blood glucose of 120 mg/dL, temp of 101 F, pulse of 88 bpm, respirations of 22, and blood
pressure of 100/72. Which finding would be of most concern to the nurse?
"1. Pulse
2. Respiration
3. Temperature
4. Blood pressure"
3) temp. An elevated temperature may indicate infection. Infection is a leading cause of hyperglycemic
hyperosmolar nonketotic syndrome or diabetic ketoacidosis. The other findings noted in the question
are within normal limits.
"A nurse should recognize which symptom as a cardinal sign of diabetes mellitus?
"a. Nausea
b. Seizure
c. Hyperactivity
d. Frequent urination
"D. Frequent Urination
Polyphagia, polyuria, polydipsia, and weight loss are cardinal signs of DM. Other signs include
irritability, shortened attention span, lowered frustration tolerance, fatigue, dry skin, blurred vision,
sores that are slow to heal, and flushed skin."
A patient is admitted with diabetes mellitus, has a glucose level of 380 mg/dl, and a moderate level of
ketones in the urine. As the nurse assesses for signs of ketoacidosis, which of the following respiratory
patterns would the nurse expect to find?"
A-Central apnea
B-Hypoventilation
C-Kussmaul respirations
D- Cheyne-Stokes respirations"
C-Kussmaul respirations. In diabetic ketoacidosis, the lungs try to compensate for the acidosis by
blowing off volatile acids and carbon dioxide. This leads to a pattern of Kussmaul respirations, which
are deep and nonlabored.
"A patient with type 1 diabetes has received diet instruction as part of the treatment plan. The nurse
determines a need for additional instruction when the patient says,
"a. ""I may have an occasional alcoholic drink if I include it in my meal plan.""
b. ""I will need a bedtime snack because I take an evening dose of NPH insulin.""
c. ""I will eat meals as scheduled, even if I am not hungry, to prevent hypoglycemia.""
d. ""I may eat whatever I want, as long as I use enough insulin to cover the calories.
"D. ""I may eat whatever I want, as long as I use enough insulin to cover the calories.""
Rationale: Most patients with type 1 diabetes need to plan diet choices very carefully. Patients who
are using intensified insulin therapy have considerable flexibility in diet choices but still should restrict
dietary intake of items such as fat, protein, and alcohol. The other patient statements are correct and
indicate good understanding of the diet instruction."
"An 18-year-old female client, 5'4'' tall, weighing 113 kg, comes to the
clinic for a non-healing wound on her lower leg, which she has had for two weeks. Which disease
process should the nurse suspect the client is developing?
A. Type 1 diabetes
B. Type 2 diabetes
C. Gestational diabetes
D. Acanthosis nigricans"
CORRECT -->B. Type 2 diabetes is a disorder usually occurring around the age of 40, but it is now being
detected in children and young adults as a result of obesity and sedentary lifestyles. Non-healing
wounds are a hallmark sign of type 2 diabetes. This client weights 248.6
lbs and is short.
C. Gestational diabetes occurs during pregnancy. There is no mention of this.
D. Acanthosis nigricans (AN), dark pigmentation and skin creases in the neck is a sign of
hyperinsulinemia. The pancreas is secreting excess amounts of insulin as a result of excessive caloric
intake. It is identified in young children and is a precursor to the development of type 2 diabetes."
"An adolescent client with type I diabetes mellitus is admitted to the emergency department for
treatment of diabetic ketoacidosis. Which assessment findings should the nurse expect to note?
"a) sweating and tremors
b) hunger and hypertension
c) cold, clammy skin and irritability
d) fruity breath and decreasing level of consciousness
