1. A client is brought to the emergency department in an unresponsive state, and a
diagnosis of hyperosmolar hyperglycemic syndrome is made. The nurse would
immediately prepare to initiate which anticipated health care provider's prescription?
1. Endotracheal intubation
2. 100 units of NPH insulin
3. Intravenous infusion of normal saline
4. Intravenous infusion of sodium bicarbonate
Answer:
3. Intravenous infusion of normal saline
Rationale:
The primary goal of treatment in hyperosmolar hyperglycemic syndrome (HHS) is to
rehydrate the client to restore fluid volume and to correct electrolyte deficiency.
Intravenous (IV) fluid replacement is similar to that administered in diabetic
ketoacidosis (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 HHS.
2. An external insulin pump is prescribed for a client with diabetes mellitus. When the
client asks the nurse about the functioning of the pump the nurse bases the response on

2. An external insulin pump is prescribed for a client with diabetes mellitus. When the
client asks the nurse about the functioning of the pump, the nurse bases the response on
which information about the pump?
1. It is timed to release programmed doses of either short-duration or NPH insulin into
the bloodstream at specific intervals.
2. It continuously infuses small amounts of NPH insulin into the bloodstream while
regularly monitoring blood glucose levels.
3. It is surgically attached to the pancreas and infuses regular insulin into the pancreas.
This releases insulin into the bloodstream.
4. It administers a small continuous dose of short-duration insulin subcutaneously. The
client can self-administer an additional bolus dose from the pump before each meal.
Answer:
4. It administers a small continuous dose of short-duration insulin
subcutaneously. The client can self-administer an additional bolus dose
from the pump before each meal.
Rationale:
An insulin pump provides a small continuous dose of short-duration (rapid- or short-
acting) insulin subcutaneously throughout the day and night. The client can self-
administer an additional bolus dose from the pump before each meal as needed. Short-
duration insulin

3. A client with a diagnosis of diabetic ketoacidosis (DKA) is being treated in the
emergency department. Which findings support this diagnosis? Select all that apply.
1. Increase in pH
2. Comatose state
3. Deep, rapid breathing
4. Decreased urine output
5. Elevated blood glucose level
Answers:
2. Comatose state
3. Deep, rapid breathing
5. Elevated blood glucose level
Rationale:
Because of the profound deficiency of insulin associated with DKA, glucose cannot be
used for energy and the body breaks down fat as a secondary source of energy. Ketones,
which are acid byproducts of fat metabolism, build up and the client experiences a
metabolic ketoacidosis. High serum glucose contributes to an osmotic diuresis and the
client becomes severely dehydrated. If untreated, the client will become comatose due to
severe dehydration, acidosis, and electrolyte imbalance. Kussmaul's respirations, the
deep rapid breathing associated with DKA, is a compensatory mechanism by the body.
The body attempts to correct the acidotic state by blowing off carbon dioxide (CO2),
which is an acid. In the absence of insulin, the client will experience severe
hyperglycemia. Option 1 is incorrect because in acidosis the pH would be low. Option 4
is incorrect because a high serum glucose will result in an osmotic diuresis and the client
will experience polyuria

4. The nurse teaches a client with diabetes mellitus about differentiating between
hypoglycemia and ketoacidosis. The client demonstrates an understanding of the
teaching by stating that a form of glucose should be taken if which symptom or
symptoms develop? Select all that apply.
1. Polyuria
2. Shakiness
3. Palpitations
4. Blurred vision
5. Lightheadedness
6. Fruity breath odor
Answers:
2. Shakiness
3. Palpitations
5. Lightheadedness
Rationale:
Shakiness, palpitations, and lightheadedness are signs/symptoms of hypoglycemia and
would indicate the need for food or glucose. Polyuria, blurred vision, and a fruity breath
odor are manifestations of hyperglycemia.
