The nurse is caring for a 68-year-old client in the emergency department.
Nurses' Notes,
Emergency Department
1020:
The client reports shortness of breath, a 2-lb weight gain over the past week, and lower extremity swelling. The client
reports slight chest discomfort during activity that is relieved with rest. Medical history is significant for hypertension.
myocardial infarction, heart failure, coronary artery disease, and chronic stable angina. Current medications include
metoprolol, furosemide, potassium chloride, lisinopril, and aspirin. The client takes all medications as prescribed except
one; he states, "I do not take that water pill because I got tired of having to go to the bathroom all the time."
S1 and S2 are present; a prominent S3 is heard. Respirations are labored with inspiratory crackles in the middle and at the
base of the lungs. The abdomen is soft and nontender with normoactive bowel sounds. There is 3+ pitting edema in the
bilateral lower extremities.

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 Nurses' Notes, Vital Signs, and Laboratory Results.The nurse is reviewing the client's response to potassium-lowering therapies. Which finding is unexpected and requires follow-up by the nurse?
Correct Answer: A
Rationale: Treatment for hyperkalemia includes administration of calcium gluconate, furosemide, albuterol nebulizer, and insulin with dextrose. These
therapies may cause rapid shifts in fluid volume, blood glucose, and serum electrolytes. Insulin shifts available glucose and potassium into
the cell, lowering serum potassium levels; however, too much insulin and not enough dextrose cause hypoglycemia (eg, blood glucose 50
mg/dL [2.7 mmol/L]). Clients with kidney disease have an increased risk of hypoglycemia because insulin may accumulate.
The nurse should understand that a low blood glucose level and symptoms suspicious for hypoglycemia (eg, diaphoresis) require follow-u
to prevent seizures, coma, and death due to lack of circulating glucose (Option 1). This client requires an additional dose of dextrose.
(Option 2) This client's blood pressure is 146/88 mm Hg and heart rate is within normal limits. This is an improvement from the initial blood
pressure and represents a therapeutic response to furosemide administration. Blood pressure should be lowered slowly to avoid hypotensior

Question 3 of 5
For each finding below, click to specify if the finding is consistent with the disease process of infective endocarditis, pericarditis, or pneumonia. Each finding may support more than one disease process.
| Finding | Infective Endocarditis | Pericarditis | Pneumonia |
|---|---|---|---|
| New or worsening cardiac murmurs | |||
| Muffled heart sounds on auscultation | |||
| Splinter hemorrhages on the nail beds | |||
| Presence of flu-like symptoms and fever | |||
| Substernal pain that is aggravated by inspiration |
Correct Answer:
Rationale: Infective endocarditis occurs when an infectious organism forms a vegetation on a heart valve (interior of the heart). Clients
often have nonspecific symptoms of infection such as fever, flu-like symptoms (myalgia, arthralgia), and malaise.
Vegetation on a heart valve makes the valve dysfunctional, creating a new or worsening cardiac murmur. Pieces of
endocardial vegetation can break off, forming microemboli that travel through the arteries to end-capillaries and block blood
flow (eg, splinter hemorrhages on the nail beds), and cause erythematous macular lesions on the palms or soles (Janeway
lesions).
Acute pericarditis is inflammation of the membranous sac surrounding the exterior of the heart (pericardium), which often
causes an increased fluid in the pericardial cavity (ie, pericardial effusion). If pericardial effusions accumulate rapidly or are
very large, they may compress the heart, altering the mechanics of the cardiac cycle (ie, cardiac tamponade). Clinical
manifestations of pericarditis include muffled heart sounds on auscultation, presence of flu-like symptoms and fever, and
substernal pain that is aggravated by inspiration (ie, pleuritic chest pain). Pericardial friction rub, a superficial scratching or
squeaky sound, may be present, but cardiac murmurs are not present (no valve involvement) and embolic phenomena are
uncommon.
Pneumonia is an infection in the lungs that results in the production of cellular debris and purulent secretions that obstruct the
alveoli and prevent adequate oxygenation. Clinical manifestations include the presence of flu-like symptoms and fever,
pleuritic chest pain, tachycardia, low capillary oxygen saturation (SpO2), crackles, and productive cough with purulent
sputum.
Question 4 of 5
Select below the 4 findings that are most concerning at this time.
Correct Answer: B,C,D,F
Rationale: This client has multiple findings concerning for infective endocarditis (IE), which occurs when an infectious organism enters the
innermost layer of the heart (ie, endocardium) and forms a vegetation on a heart valve. Findings concerning for IE include:
• Recent tooth extraction: Dental procedures (eg, tooth extraction) increase the risk for infectious organisms entering the
bloodstream, potentially leading to IE. Other risk factors include a history of IV drug use, presence of a distant infection
(eg, leg cellulitis), or presence of a prosthetic heart valve
• Fever: Elevated temperature is a sign of infection, which is a common finding in clients with IE.
• Nontender, erythematous, macular lesions on the palms or soles (Janeway lesions): Janeway lesions are
characteristic of IE. They occur when turbulent blood flow through the heart valves causes pieces of endocardial
vegetation to break off, forming microemboli that travel through the arteries to end-capillaries and block blood flow.
• Nonblanching, thin, red/dark longitudinal lines under the nail beds (splinter hemorrhages): Like Janeway lesions,
splinter hemorrhages are caused by microemboli that break off from vegetative lesions in the heart and travel through the
arteries to end-capillaries and block blood flow.

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 5 of 5
The client returns to the clinic 6 months after starting behavioral therapy. Which statement by the parent indicates a need for further therapy?
Correct Answer: A
Rationale: Early childhood intervention programs (eg, behavioral therapy) are a critical component for clients with autism spectrum
disorder and can have positive long-term effects on presenting symptoms and social skills. Therapy helps increase
communication and language skills; improve focus, social skills, memory, and academic functioning; and decrease problematic
behaviors through positive reinforcement and other behavioral approaches
When evaluating the outcomes of therapy, the nurse should recognize that clients who demonstrate narrowed, restricted
interests (eg, eating the same foods) indicate a need for additional therapy
