Question 1 of 5
Drag words from the choices below to fill in the blank/blanks. The nurse understands that treatment for diabetic ketoacidosis is resolved when the-----------,--------, and ----------
Correct Answer: B,D,E
Rationale: Diabetic ketoacidosis (DK
A) causes anion gap metabolic acidosis generated by the ketoacid anions and beta-hydroxybutyrate. Anion gap is
calculated based on electrolyte levels to determine the balance of cations and anions (le, acids and bases).
IV insulin infusion may be discontinued on resolution of acidosis and ketosis, which generally occurs with a blood glucose level of <200
mg/dL (11.1 mmol/L). However, measurement of serum glucose alone is inappropriate for monitoring the response to treatment because
ketosis and acidemia may still be present. With fluid resuscitation and correction of hyperosmolality and hyperglycemia, ketoacids disappear
and the anion gap and arterial blood gas results normalize, pointing to resolution of metabolic acidosis and ketonuria ie, ketones in
urine.

Question 2 of 5
The nurse reinforces discharge teaching to the client after laser peripheral iridotomy. Which of the following client statements indicate an understanding of the teaching? Select all that apply.
Correct Answer: A,B,C,D,E
Rationale: Laser peripheral iridotomy is a surgical intervention for acute angle-closure glaucoma (ACG) that involves creating a small hole in the iris to
prevent the drainage pathway from closing and improve movement of aqueous humor into regular outflow channels. Ophthalmic alpha-
adrenergic agonists (eg, apraclonidine, brimonidine) are administered postoperatively to reduce aqueous humor production and prevent an
elevation in intraocular pressure.
Important considerations for the administration of ophthalmic drops include:
• Pulling the lower eyelid down by gently pressing on the lower orbital bone to expose the conjunctival sac (Option 1)
• Applying pressure over the inner corner of the eye (eg, lacrimal duct) after each medication to avoid systemic absorption (Option 2)
• Waiting at least 5 minutes before instilling a different medication into the same eye to allow absorption of the first medication and to
avoid overflow with multiple drops (Option 4)
• Holding the dropper ½*% in (1-2 cm) above the conjunctival sac to prevent contamination of the dropper and infection of the eye
(Option 5)
Clients should also be instructed to consult with their health care provider before taking over-the-counter medications (eg, decongestants,
anticholinergics, antihistamines) because a subsequent episode of acute ACG may be triggered by certain medications (Option 3).

Nurses' Notes
Urgent Care Clinic
0845: The parent brought the client to the clinic due to vomiting and weakness. The parent states that the client has experienced
sore throat and nasal congestion for the past week. The client has had 4 episodes of emesis during the past 24 hours and
diffuse, constant abdominal pain. The parent also reports that the client has had increased thirst and urine output over the
past 2 months.
The client's last menstrual period ended approximately 6 weeks ago with no abnormalities. Pregnancy status is unknown. The
client does not take any medications and does not use tobacco, alcohol, or recreational substances. Family history includes
hypertension and diabetes mellitus.
The client appears drowsy and is oriented to person and time only. The abdomen is soft without rigidity or rebound
tenderness, and bowel sounds are normal. No blood is present in emesis. Respirations are rapid and deep. Breath sounds
are clear.
Vital signs are T 98.8 F (37.1 C), P 128, RR 30, and BP 88/60 mm Hg.
Finger-stick blood glucose level is 600 mg/dL (33.3 mmol/L).
Question 3 of 5
For each potential finding below, click to specify if the finding is consistent with the disease process of diabetic ketoacidosis, ruptured appendix, or ruptured ectopic pregnancy. Each finding may support more than one disease process.
| Finding | Diabetic ketoacidosis | Ruptured appendix | Ruptured ectopic pregnancy |
|---|---|---|---|
| Polyuria | |||
| Vomiting | |||
| Tachypnea | |||
| Tachycardia | |||
| Hyperglycemia | |||
| Abdominal pain |
Correct Answer:
Rationale: Diabetic ketoacidosis (DK
A) is a complication of diabetes mellitus that results from lack of insulin. Insulin is required to transport glucose
into cells for energy, which means that lack of insulin leads to intracellular starvation despite the high level of glucose circulating in the blood
(hyperglycemia). Physiologic responses to hyperglycemia include osmotic diuresis (polyuria) for reduction of blood glucose levels and
breakdown of fat into acidic ketone bodies for energy. This leads to states of dehydration (as evidenced by tachycardia), electrolyte
imbalance, and metabolic acidosis. Ketoacidosis leads to tachypnea and deep respirations (Kussmaul respirations), as well as abdominal
pain and vomiting.
Appendicitis is an inflammation of the appendix often resulting from obstruction by fecal matter. Appendiceal obstruction traps colonic fluid
and mucus, causing increased intraluminal pressure and inflammation. This impairs perfusion of the appendix, resulting in swelling and
ischemia. Clinical manifestations include fever, abdominal pain, rebound abdominal tenderness, tachycardia, nausea, and vomiting.
Abdominal pain usually begins near the umbilicus and migrates to the right lower quadrant (eg, McBurney point). Tachypnea, as well as a
compensatory response, can be present, especially if there is a ruptured appendix or evidence of sepsis causing lactic acidosis (metabolic
acidosis).

Question 4 of 5
The nurse has reviewed the information from the Laboratory Results and Nurses' Notes. Which of the following nursing actions are anticipated? Select all that apply
Correct Answer: A,B
Rationale: The goal of treatment of diabetic ketoacidosis (DK
A) is to normalize fluid volume, decrease blood glucose levels, balance electrolytes, and
correct metabolic acidosis. On administration of insulin, potassium and glucose shift from the extracellular space to the intracellular space.
Clients with DKA require potassium administration due to low intracellular potassium levels.
Insulin is administered to facilitate glucose transport into the intracellular space to resolve DKA and should be continued until the metabolic
acidosis resolves. When caring for clients with DKA, the nurse should anticipate:
• Adding 5% dextrose to continuous IV fluids when the serum blood glucose level reaches approximately 200 mg/dL (11.1 mmol/L) to
prevent hypoglycemia and cerebral edema resulting from levels decreasing too quickly (Option 1). This is done because insulin is still
required to resolve DKA. If the DKA is resolved, insulin can also be decreased instead of adding dextrose to the IV fluids.
• Administering potassium chloride for a client with hypokalemia and adequate urine output (ie, >30 mL/hr) to prevent life-threatening
arrhythmias

Question 5 of 5
The nurse receives prescriptions for medications to treat the client's hyperkalemia. For each medication, click to specify if the medication drives potassium from blood into cells, promotes potassium excretion, or stabilizes myocardial cell membranes.
| Medication | Drives Potassium from Blood into cells | Promotes Potassium Excretion | Stabilizes Myocardial Cell Membranes |
|---|---|---|---|
| Furosemide | |||
| Albuterol nebulizer | |||
| Calcium gluconate | |||
| Insulin and dextrose |
Correct Answer:
Rationale: Several medications can rapidly correct a client's hyperkalemia by:
• Driving potassium from blood into cells: The serum potassium level can be temporarily lowered by administering an albuterol
nebulizer and IV insulin. Although albuterol and insulin are not usually administered for this purpose, they also shift potassium from the
extracellular space to the intracellular space. Because insulin transports both glucose and potassium into the cell, dextrose is
administered in combination with insulin to prevent hypoglycemia. Albuterol is not often used alone for hyperkalemia; it is often
administered with insulin and dextrose to improve the potassium-lowering effect.
• Promoting potassium excretion: Administration of loop diuretics (ie, potassium-wasting diuretics such as furosemide) will increase
the amount of potassium excreted into the urine at the loop of Henle and also treat the client's acute fluid volume overload.
• Stabilizing myocardial cell membranes: Administration of calcium gluconate antagonizes potassium and protects the myocardium
from potassium-induced dyshythmias by blocking potassium's effects and reducing myocardial irritability. Calcium gluconate does not
alter serum potassium levels and is usually indicated if there are ECG changes with hyperkalemia.
