The ECG of a client with a single-chamber atrial pacemaker should display
o :## a pacemaker spike before the P wave.
On an electrocardiogram (ECG),
o :## the P wave represents atrial depolarization and the QRS complex
represents ventricular depolarization. The ECG of a client with a single-
chamber atrial pacemaker should display a pacemaker spike before the P
wave.
occurs when a blood clot becomes lodged in a vein. Clinical manifestations include
unilateral edema, localized pain, tenderness to touch, warmth, and erythema.
o :## Deep venous thrombosis
is a life-threatening complication of pericarditis that develops when fluid
accumulates within the layers of the pericardium. Clinical manifestations include
tachycardia, muffled heart tones, jugular venous distension, and pulsus paradoxus.

Clients with pericardial effusion should be
o :## monitored and assessed closely for the development of cardiac
tamponade. Signs and symptoms of tamponade include muffled or distant
heart tones, hypotension, narrowed pulse pressure, jugular venous
distension, and pulsus
indicate turbulent blood flow across diseased or malformed cardiac valves. They
are often described as musical, blowing, or swooshing sounds that occur between
normal heart sounds. They may be auscultated at the aortic, pulmonic, tricuspid,
or mitral areas.
o :## Murmurs
Clients taking estrogen therapy are at an increased risk for
o :## hypercoagulability and thromboembolic complications. Signs or
symptoms of deep venous thrombosis (eg, leg swelling, redness, pain) should
be reported to the health care provider immediately.
The nurse needs to monitor groin puncture sites, peripheral pulses, urine output,
and kidney function in the client who has had minimally invasive endovascular
repair of an abdominal aneurysm.
o :## Endovascular abdominal aortic aneurysm repair i
increases the risk of tissue necrosis and limb loss. Management focuses on
improving blood flow and circulation to the extremities through lifestyle changes
and medications.
o :## Peripheral artery disease

on ECG is characterized by an irregular rhythm with fibrillatory waves instead of P
waves. Treatment includes rate control and anticoagulation.
o :## Atrial fibrillation
is a sympathomimetic inotropic agent that increases heart rate, blood pressure,
cardiac output, and urine output. Vital signs should be monitored closely in these
clients as a higher dose can result in dangerous tachycardia and tachyarrhythmias.
o :## Dopamine
Clinical manifestations of hypovolemic shock
o :## are associated with inadequate perfusion and include urine output <0.5
mL/kg/hr, changes in mental status, hypotension, and tachycardia.
The nurse should carefully monitor renal status in a client who has had abdominal
aortic aneurysm repair.
o :## BUN, creatinine, and urine output should be assessed. Urine output of
at least 30 mL/hr is expected.
When administering furosemide, it is important to closely monitor
o :## the client's vital signs, serum electrolytes (potassium), and kidney
function tests (blood urea nitrogen, creatinine) prior to administration to
prevent side effects such as hypokalemia, hypotension, and kidney injury.
The steps for using an automated external defibrillator (AED) are as follows:
