Question 1 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.
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.

Question 2 of 5
The nurse has reviewed the information from the Laboratory Results. The client is transferred to an inpatient care facility. Which of the following orders should the nurse expect for the client? Select all that apply
Correct Answer: A,B,C,G
Rationale: Management of diabetic ketoacidosis (DK
A) initially focuses on IV fluid resuscitation to reverse hypovolemia and then correction of
hyperglycemia, electrolyte abnormalities, and acid-base imbalance. Appropriate interventions include:
• Continuous insulin IV infusion to correct hyperglycemia. IV insulin has a more rapid onset of action than subcutaneous insulin, whic
allows faster and more precise management of the blood glucose level (Option 1).
• Continuous cardiac monitoring to detect dyshythmias related to metabolic acidosis or electrolyte abnormalities (Option 2).
• Hourly finger-stick blood glucose level checks to monitor for treatment effectiveness and detect any hypoglycemia related to the
insulin infusion (Option 3).
• Isotonic IV fluid (eg, 0.9% sodium chloride) to replace fluid losses and strict intake and output monitoring to evaluate the
effectiveness of fluid resuscitation and monitor for signs of acute kidney injury (Option 6).
• Frequent monitoring of arterial blood gas levels and electrolyte levels.

Nurses' Notes
Initial Clinic Visit
1100:
The client has experienced enuresis at night for the past 2 weeks and frequently requests to use the
bathroom while at school. The client was previously toilet trained with no nighttime bed wetting for 6 months;
the client recently relocated to a new home and school where the client lives with parents.
The parent reports that the client has recently demonstrated fatigue, irritability, and multiple behavioral
outbursts that resemble past temper tantrums. The client frequently reports feeling thirsty. No dysuria or
urinary hesitancy is reported.
Weight and height were in the 40th percentiles at the previous visit a year ago. Growth charts today show
the client's weight in the 20th percentile and height in the 40th percentile.
The client appears tired and irritable. Dry mucous membranes are noted with no increased work of
breathing. The lungs are clear to auscultation bilaterally. No cardiac murmur is heard.
Question 3 of 5
Which of the following statements by the client's parent indicates a correct understanding of the teaching about management for type 1 diabetes mellitus? Select all that apply
Correct Answer: A,B
Rationale: Clients with type 1 diabetes mellitus (DM) have impaired insulin production due to autoimmune destruction of pancreatic beta
cells. Because clients with type 1 DM do not produce insulin, lifelong insulin replacement is required. Insulin requirements
will change with growth and development
Insulin requirements may increase because stressful events (eg, illness) cause blood glucose levels to rise. When the
client is ill, the parent should be instructed to notify the health care provider, monitor blood glucose levels closely, test the urine
for ketones, increase insulin administration per sliding scale, and monitor for signs of dehydration

Question 4 of 5
Complete the following sentence by choosing from the lists of options. The nurse should first address the client's -------followed by the client's --------------
Correct Answer: A,D
Rationale: Hyperglycemia in diabetic ketoacidosis (DK
A) causes osmotic diuresis that leads to severe dehydration. When hyperglycemia exceeds the
renal threshold of glucose absorption, glucosuria (excretion of glucose in urine) occurs. Water loss is increased due to osmotic diuresis
induced by glucosuria, and extreme dehydration, hypotension, and decreased organ perfusion occur.
The priority intervention in DKA is to initiate an IV fluid bolus with 0.9% sodium chloride followed by insulin administration to lower serum
glucose levels. Rapid fluid resuscitation should occur before insulin infusion because insulin shifts water, potassium, and glucose into the
cells, worsening extracellular dehydration and electrolyte imbalances.
Therefore, for clients with DKA, the nurse should first address
hypovolemia followed by hyperglycemia.

Question 5 of 5
The nurse reinforces teaching about managing diabetes mellitus during an acute illness. For each of the statements made by the client,click to specify whether the statement indicates correct understanding or incorrect understanding
| Client Statements | Correct | Incorrect |
|---|---|---|
| I should not take insulin if I cannot eat due to nausea. | ||
| I should drink extra fluids to stay hydrated when I am experiencing an illness. | ||
| I will check my blood glucose levels more frequently if I am experiencing an illness | ||
| I need to check my urine for ketones if my blood glucose levels are persistently elevated | ||
| I will reduce my carbohydrate intake if I experience high blood glucose levels during an illness. |
Correct Answer:
Rationale: When a client with diabetes mellitus experiences an infection or another illness, the release of stress hormones can cause increased insulin
resistance, which increases the blood glucose level and leads the body to break down fats for energy (ketosis). This can precipitate diabeti
ketoacidosis (DK
A) as break down of fatty acids produces ketones. Interventions for managing diabetes mellitus and preventing DKA durin
an illness include:
• Increasing fluid intake to help clear ketones from the system and prevent dehydration during illness
• Checking blood glucose levels more frequently (eg, every 4 hr) to monitor for hyperglycemia
• Monitoring the urine for ketones if blood glucose levels are persistently elevated (>240 mg/dL [13.3 mmol/L]) for early detection of
impending DKA
• Consuming beverages that contain glucose and replacing electrolytes if nausea and vomiting are present
• Notifying the health care provider of persistently elevated blood glucose levels, ketones in the urine, high fever, nausea, vomiting, or
diarrhea
