Question 1 of 5
Select 4 clinical findings that require immediate follow-up.
Correct Answer: A,B,C,E
Rationale: Type 1 diabetes mellitus is an endocrine disorder characterized by the absence of insulin production in the pancreas. Glucose requires insulin
to be transported from the extracellular space into the cell. Without insulin, glucose continues to circulate in the extracellular space, causing
serum hyperglycemia and intracellular glucose starvation that can lead to diabetic ketoacidosis (DK
A).
In DKA, the body breaks down fat for energy (ie, ketosis). This leads to high levels of ketones in the blood, which can cause life-threatening
metabolic acidosis. Clinical findings concerning for DKA require immediate follow-up and include:
• Nausea, vomiting, and abdominal pain—a common presentation of DKA (especially in children) that can be related to delayed gastric
emptying and/or ileus from electrolyte abnormalities and metabolic acidosis
• Neurologic symptoms (eg, lethargy, obtundation) due to progressive hyperglycemia and acidosis
• Signs of dehydration (eg, dry mucous membranes, prolonged P3 sec] capillary refill time) due to osmotic water loss caused by
glucose in the urine

Question 2 of 5
The nurse has reviewed the information from the Laboratory Results. Complete the following sentence/sentences by choosing from the list/lists of options.The nurse should prioritize interventions to treat ------------ due to the risk of ---------------------.
Correct Answer: A,B
Rationale: The client's laboratory results show hyperkalemia (ie, high potassium) and decreased kidney function, seen as elevated BUN and creatinine.
The kidneys balance potassium levels by eliminating excess potassium through urine. Clients with heart failure (HF) are at an increased risk fo
hyperkalemia due to poor kidney perfusion from decreased cardiac output and medication adverse effects. This client's decreased kidney
function and home medications, including lisinopril (ACE inhibitor) and supplemental potassium chloride, all increase the risk of hyperkalemia.
Because potassium is responsible for myocardial cell repolarization, hyper- or hypokalemia may lead to life-threatening dysrhythmias.
Therefore, the nurse should prioritize interventions to treat hyperkalemia due to the risk of dysrhythmias.

Nurses' Notes
Outpatient Clinic
Initial
visit
The child recently started attending a new preschool and hit a teacher during lunch. The parent says,
"My
child has never been aggressive before but has always been particular about food."
The client was born at full term without complications and has no significant medical history. The child
started babbling at age 6 months, and the parent reports that the first words were spoken around age 12
months. The client then became quiet and "obsessed" with stacking blocks and organizing toys by color.
The child can kick a ball, draw a circle, pedal a tricycle, and now says two-word phrases. Vitals signs are
normal, and the client is tracking adequately on growth curves.
During the evaluation, the child sits in the corner of the room playing with blocks. The client does not follow
the parents gaze when the parent points to toys in the office. The child begins screaming and rocking back
and forth when the health care provider comes near.

Question 3 of 5
Which of the following findings indicate that the client is improving as expected? Select all that apply.
Correct Answer: A,B,C,D
Rationale: Clinical improvement in a client with heart failure includes manifestations of reduced cardiac workload and improved fluid
volume status and gas exchange. A decrease in blood pressure from 170/100 mm Hg to 138/70 mm Hg and increased
urinary output indicate effectiveness of diuretics to reduce circulatory fluid volume and antihypertensive medications to
decrease cardiac workload . In addition, clear lung sounds and an increased capillary oxygen
saturation (SpO2) indicate a decrease in pulmonary congestion and an improvement in fluid volume status

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 4 of 5
For each client finding below, click to specify if the finding is consistent with the disease process of behavior regression,diabetes mellitus, or urinary tract infection. Each finding may support more than one disease process.
| Finding | Behavior Regression | Diabetes Mellitus | Urinary Tract Infection |
|---|---|---|---|
| Fatigue | |||
| Irritability | |||
| Polydipsia | |||
| Urinary frequency | |||
| Nocturnal enuresis |
Correct Answer:
Rationale: Behavior regression is the return to a previous behavior as an act of coping. This may be caused by a stressful event (eg,
new school, parental divorce, relocation). Clinical findings may include withdrawal or the return of previous behaviors that
resemble toddlerhood (eg, temper tantrums [fatigue, irritability], nocturnal enuresis).
Diabetes mellitus (DM) is a metabolic disorder characterized by insulin deficiency (type 1 DM) or resistance (type 2 DM),
which leads to increased blood glucose levels (ie, hyperglycemia) and signs of cellular starvation (eg, fatigue, irritability,
weight loss) from decreased glucose use. Glucose increases the osmolality of blood, which pulls water into the intravascular
space and leads to excessive urination (eg, urinary frequency, nocturnal enuresis). As the kidneys excrete excess glucose,
the body loses water, resulting in hypovolemia and signs of dehydration (eg, increased thirst [polydipsial, dry mucous
membranes).
A urinary tract infection is an infection of the urethra, bladder, ureters, and/or kidneys. Common manifestations include
fatigue, fever, painful urination (ie, dysuria), urinary frequency and urgency, and nocturnal enuresis. Irritability may be a
sign of illness in a child who has difficulty verbalizing or understanding the cause of the symptoms. Although increased urinary
frequency is seen (due to bladder irritation), volume is not excessive (unlike osmotic diuresis of DM); therefore, clients are not
dehydrated and would not report polydipsia.

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.
