NCLEX RN UWORLD 2025 Questions With Accurate
Answers.
The ECG of a client with a single-chamber atrial pacemaker should display -
accurate answers-a pacemaker spike before the P wave.
On an electrocardiogram (ECG), - accurate answers-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. - accurate answers-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. - accurate answers-Explanation
Cardiac tamponade
Clients with pericardial effusion should be - accurate answers-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. - accurate answers-Murmurs
Clients taking estrogen therapy are at an increased risk for - accurate
answers-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. - accurate answers-
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. - accurate answers-Peripheral artery disease
on ECG is characterized by an irregular rhythm with fibrillatory waves instead
of P waves. Treatment includes rate control and anticoagulation. - accurate
answers-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. - accurate answers-Dopamine
Clinical manifestations of hypovolemic shock - accurate answers-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. - accurate answers-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 - accurate
answers-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: -
accurate answers-turn on the defibrillator, place the pads on the client's chest,
continue chest compressions until the AED is ready to analyze the rhythm,
charge the defibrillator, ensure staff members are all clear, deliver the shock,
then resume compressions immediately.
Fluid volume deficit - accurate answers-is commonly caused by vomiting and
diarrhea; treatment includes IV fluid resuscitation. Signs of adequate
rehydration include capillary refill time <2 seconds, adequate urine output
, (>30 mL/hr), and normal urine specific gravity (1.005-1.030). Narrowed
pulse pressure occurs with hypovolemic shock, and orthostatic hypotension is
indicative of ongoing fluid volume deficit.
cardiogenic shock - accurate answers-Clients with cardiomyopathy may
develop cardiogenic shock due to the heart's inability to circulate blood
effectively, causing reduced cardiac output. Treatment of cardiogenic shock
includes supplemental oxygen, an ECG, cardiac enzyme testing, and
interventions to reduce cardiac workload.
Acute blood loss - accurate answers-(eg, gastrointestinal bleeding) is a
medical emergency. The nurse should place the client in the supine position
with the feet elevated to maintain blood perfusion to the brain and other vital
organs.
Stable angina - accurate answers-is predictable, intermittent chest pain that
occurs when myocardial oxygen demand exceeds supply, most often caused
by atherosclerosis. Pain is often precipitated by stress, emotional upset,
tobacco use, strenuous activities (eg, exercise), and exposure to extreme
temperatures.
The nurse should recognize VF, a potentially lethal dysrhythmia. The ECG
shows irregular waveforms of varying shapes and amplitudes. The client is
unresponsive, pulseless, and apneic. Rapid treatment should include CPR,
defibrillation, and drug therapy (eg, epinephrine, vasopressin, amiodarone). -
accurate answers-Ventricular fibrillation (VF)
in women, the elderly, and diabetics may have gastrointestinal distress as the
main symptom; this needs to be evaluated with the institutional protocol for
acute coronary syndrome. - accurate answers-Myocardial infarctions
The client in VT must be assessed for the presence or absence of a pulse
before further assessment or treatment is initiated. The unstable
(hypotensive) client in VT with a pulse is treated with synchronized
cardioversion. - accurate answers-Ventricular tacycardia
In a client with hypomagnesemia, it is important to assess the QT interval. The
client is most at risk for torsades de pointes, a serious complication that can
