Question 1 of 5
The nurse has implemented the prescribed therapies and is now assisting the client to fill out the lunch menu. Which meal choice is best for this client?
Correct Answer: B
Rationale: This client is experiencing hyperkalemia and should reduce dietary intake of potassium. The preferred meal choice for this client would
include lean meat, such as chicken, that is grilled rather than cooked in oil, and side dishes consisting of fruits and vegetables low in
potassium, such as corn and applesauce (Option 2).
(Options 1, 3, and 4) Beans (a legume), salmon, tomatoes, bananas, potatoes, strawberries, whole wheat products, and avocados are all
high-potassium foods that the client should avoid at this time. Clients with cardiovascular disease should not consume red meat (eg,
hamburger patty) except in limited quantity because it is high in saturated fat.
Question 2 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.

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).

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 4 of 5
For each finding below, click to specify if the finding is consistent with the expected action of the medication carvedilol, enalapril, or furosemide. Each finding may support more than one medication.
| Finding | Carvedilol | Enalapril | Furosemide |
|---|---|---|---|
| Decreases heart rate | |||
| Increases urinary output | |||
| Decreases blood pressure | |||
| Increases oxygen saturation |
Correct Answer:
Rationale: Pharmacologic management of heart failure (HF) focuses on reducing cardiac workload and improving cardiac output.
• Beta-adrenergic antagonists ("beta blockers") (eg, carvedilol) reduce cardiac workload by inhibiting the action of
catecholamines (eg, epinephrine, norepinephrine) on beta-adrenergic receptors in the heart. Beta blockers decrease
myocardial oxygen demand by decreasing blood pressure and decreasing heart rate.
• Angiotensin-converting enzyme (ACE) inhibitors (eg, enalapril) alter the renin-angiotensin-aldosterone system by
inhibiting conversion of angiotensin I to angiotensin II, thereby preventing the release of aldosterone. Aldosterone, an
adrenal steroid hormone, retains sodium and water in addition to promoting vasoconstriction. By reducing circulating
aldosterone, ACE inhibitors promote vasodilation and as a result decrease blood pressure. ACE inhibitors also
decrease ventricular remodeling, an added benefit for clients with HF.
• Loop diuretics (eg, furosemide) prevent reabsorption of sodium and chloride in the kidneys, which increases urine
output and fluid excretion. Decreases in circulating fluid volume will decrease blood pressure and reduce pulmonary
edema (ie, increase oxygen saturation), as well as decrease cardiac preload.

Emergency Department
3 years The client is brought to the emergency department by the parents, who report that the child became upset
later
and started banging the head against the wall several times. The parents report that the client has had
these episodes frequently; however, this time, the child was injured. The client has a laceration on the
forehead and is admitted for 24-hour observation.
Question 5 of 5
The nurse has reviewed the information from the Nurses' Notes. For each potential intervention, click to specify if the intervention is anticipated or not anticipated for the care of the client.
| Potential Intervention | Anticipated |
|---|---|
| Encourage the client to play with others in the playroom | |
| Follow a structured routine and schedule for providing care | |
| Consistently assign the same nursing staff to the client when possible | |
| Assign the client to a shared room with another client who has autism | |
| Use direct eve contact and therapeutic touch when talking to the client |
Correct Answer:
Rationale: Clients with autism spectrum disorder (AS
D) are often hesitant about changes and have a heightened behavioral response
when placed in an unfamiliar environment (eg, hospital). The nurse should consider the client's unique needs when planning
care. Anticipated interventions for decreasing anxiety and enhancing cooperation when caring for clients with ASD include:
• Following a structured routine and schedule for providing care to reduce distress and promote normalcy
• Consistently assigning the same nursing staff to the client when possible to facilitate trust and communication
because clients with ASD often have difficulties adjusting to changes in their surroundings
• Establishing a method for communication that is brief, concrete, and developmentally appropriate (eg, picture boards) to
decrease frustration due to impaired verbal and nonverbal communication
Clients with ASD are hypersensitive to environmental factors and may become distressed and overstimulated by noise and
activity.
Therefore, encouraging the client to play with others in the playroom and assigning the client to a shared room
with another client who has autism are not anticipated
Clients with ASD may be fearful of, or hypersensitive to, touch and direct eye contact. The nurse should use other means of
developing trust (eg, being consistent, conveying acceptance, using positive reinforcement).
