Q

Valsalva maneuver

A

holding the breath while bearing down and contracting the abdominal muscles (eg, straining during defecation)

simulates the vasovagal response, causing
-bradycardia
-decreased CO
-hypotension
-provokes dysrhythmias.

facilitates voiding, equalizes ear pressure, treats supraventricular tachycardia, and is an adjunctive technique to avoid an air embolism when a line (eg, central venous access device) or drain is removed

contraindicated:
Clients with glaucoma or recent eye surgery (eg, cataract surgery) because straining increases intraocular pressure

Clients unable to hemodynamically compensate due to certain heart conditions (eg, heart failure, myocardial infarction) When the client relaxes, blood flow rapidly returns to the heart. If the heart is unable to compensate for the blood flow increase, fatal complications can occur.

Clients recently diagnosed with increased intracranial pressure, stroke, or a head injury. Straining increases intraabdominal and intrathoracic pressure, which raises the intracranial pressure.

Clients with portal hypertension related to cirrhosis. Straining should be avoided due to the risk of variceal bleeding induced by increased pressure

Q

arteriovenous malformation

A

a tangle of veins and arteries that is believed to form during embryonic development

The tangled vessels do not have a capillary bed, causing them to become weak and dilated

AVMs are usually found in the brain and can cause seizures, headaches, and neurologic deficits

blood pressure control is crucial

high risk for having an intracranial bleed

Any neurologic changes, sudden severe headache, nausea, and vomiting should be evaluated immediately as these are usually the first symptoms of a hemorrhage

Q

Guillain-Barré syndrome

Aspiration pneumonia
Respiratory failure
Cardiac arrhythmias
Pressure injuries
Venous thromboembolism
Ileus

A

follows a respiratory or gastrointestinal infection that triggers an immune response => peripheral nerve inflammation.

S/s:
ascending, symmetric muscle paralysis and areflexia (ie, absence of reflexes) that can eventually progress to involve the thorax and cranial nerves

monitor for the following findings:

Blood pressure variability: Autonomic dysfunction is common in GBS and can cause blood pressure/heart rate instability, leading to hypertension, hypotension, or dysrhythmias

Decreased respiratory rate and depth: These occur when ascending muscle weakness progresses to the thorax. The nurse should monitor for signs of respiratory distress (eg, decreased capillary oxygen saturation, hypoventilation, breathlessness while speaking, labored breathing) and be prepared for intubation if the client is unable to independently ventilate due to thoracic muscle paralysis

Difficulty swallowing: Paralysis and weakness of the cranial nerves make eating and swallowing difficult, increasing the risk for aspiration pneumonia. In addition, difficulty swallowing may be a warning sign of impending respiratory compromise.

Urinary retention: This occurs secondary to autonomic dysfunction. Clients with GBS may need temporary intermittent urinary catheterization

Q

Thrombolytics (ie, tissue plasminogen activators [tPA]) (eg, alteplase, reteplase)

A

used to lyse (ie, break apart) thrombi (eg, clots)

Ask the client’s caretaker about history of recent surgery or trauma: Recent (ie, within 2 weeks) major surgery is an exclusion to thrombolytic therapy because tPA dissolves all clots in the body and may therefore disrupt the surgical site and cause bleeding

Maintain BP ≤185/110: BP >185/110 mm Hg is an exclusion to thrombolytic therapy due to the risk for intracerebral hemorrhage

Review the client’s current home medication list:

for any additional anticoagulants

Verify the exact time the stroke symptoms started: Thrombolytics are time sensitive and must be administered within 3 to 4.5 hours from onset of symptoms

90
Q

Acute myeloid leukemia (AML)

A

hematologic cancer characterized by an unrestricted overproduction of immature leukocytes (ie, blasts) that invade the bone marrow and blood.

AML is diagnosed with a bone marrow biopsy

Proliferation of blasts in the bone marrow results in depressed bone marrow activity, causing pancytopenia, anemia (decreased number of RBCs), neutropenia (decreased number of WBCs), and thrombocytopenia (decreased number of platelets).

Interventions:

Implementing neutropenic precautions (eg, placing the client in a private room) to prevent infection

Administering blood products (eg, packed RBCs) to help correct anemia

Preparing the client for chemotherapy, which targets and eliminates cancer cells

Immunization with inactivated vaccines is recommended for clients who are immunocompromised
intranasal influenza = live vaccine = contraindicated

138
Q

Discharge teaching for the client with a permanent pacemaker

A

Report fever or signs of redness, swelling, or drainage at the incision site.

Always carry a pacemaker identification card and wear emergency medical identification.

Take the pulse daily and report it to the health care provider if it is below the predetermined rate.

Avoid carrying a cell phone in a pocket directly over the pacemaker and, when talking on a cell phone, hold it to the ear on the opposite side of the pacemaker

Discuss the pacemaker with health care providers before receiving an MRI; not all pacemakers are MRI safe

Notify airport security of the pacemaker; a handheld screening wand should not be held directly over the device

Avoid standing near antitheft detectors in store entryways; walk through at a normal pace and do not linger near the device.

avoid:

The client should avoid lifting the arm above the shoulder on the side of the pacemaker until approved by the health care provider because this can dislodge the pacemaker lead wires.

139
Q

Erb’s point

A

To assess the point of maximal impulse (PMI) the client is positioned supine or with the head of the bed elevated to 45 degrees; the nurse should palpate for a short tap at the midclavicular line of the fourth or fifth ICS (pulsation may or may not be visible). A displaced PMI (eg, below the fifth ICS) may be an indication of an enlarged heart.

Educational objective:
The nurse should not palpate the carotid arteries simultaneously due to possible vagal stimulation resulting in bradycardia or syncope. Each carotid artery should be palpated separately.

140

With exertion, the volume of blood pumped to the brain and other parts of the body is insufficient to meet metabolic demands, resulting in exertional dyspnea, anginal chest pain, and syncope

145
Q

Autonomic dysreflexia

spinal cord injuries above T6

A

hypertension, bradycardia, severe headache, profuse diaphoresis, and nausea

If AD is suspected, the nurse should first elevate the head of the bed to 45 degrees or higher to reduce blood pressure.

Then the nurse should assess for noxious stimuli (eg, bladder distension, fecal impactino, constructive clothes) to determine the underlying cause.

146
Q

NSAIDS is contraindicated in heart failure as these contribute to sodium retention, and therefore fluid retention.

A

NSAIDs increases the risk of thrombotic events (eg, heart attack, stroke) in clients with cardiovascular disease (eg, coronary artery disease [CAD]), especially with long-term use

152
Q

hypertriglyceridemia

A

Fibrates (eg, gemfibrozil, fenofibrate)

reduce triglyceride levels in clients with hypertriglyceridemia
increase levels of HDL (“good”) cholesterol

HMG-CoA reductase inhibitors (“statins”) may be used in combination with fibrates in clients with moderate to severe hypertriglyceridemia.

Adverse effects of fibrates and statins:

154
Q

Defibrillation

contraindications:
-asystole
-pulseless electrical activity (PEA)

Indications:
-ventricular fib
-pulseless ventricular tachycardia

A

Defibrillation attempts to convert lethal ventricular dysrhythmias (ie, ventricular fibrillation and pulseless ventricular tachycardia) into an organized rhythm by passing an electric shock through the heart.

Defibrillation cannot create an organized rhythm if there is no electrical activity in the heart

When treating asystole or PEA, the absolute priority is providing continuous, high-quality CPR and oxygenated ventilation until circulation spontaneously returns or the client enters into a shockable rhythm. Unfortunately, restoration of circulation may not be possible, and clients in asystole often cannot be resuscitated.

155
Q

Chest pain interventions

A

Instead, they can present with “atypical” symptoms such as nausea, vomiting, belching, indigestion, diaphoresis, dizziness, and fatigue.

157
Q

Neurogenic shock

A

T5 and up

causes hemodynamic decompensation due to loss of SNS response

leads to bradycardia, systemic vasodilation, and pooling of blood in the extremities, reducing venous return and cardiac output and ultimately causing impaired tissue perfusion

IV fluid bolus (eg, 0.9% sodium chloride) along with vasopressors (eg, norepinephrine) to keep the systolic blood pressure >90 mm Hg and mean arterial pressure >60 mm Hg

after,

Testing for the presence of blood in the urine is important in determining whether kidney damage has occurred

A neurological assessment (eg, level of consciousness)

Autonomic dysreflexia is a medical emergency, but it does not present for weeks to years after the initial injury.
Bladder and stool impaction are etiologies for autonomic dysreflexia and generally occur in a client with a high-level fracture at T5 or above with a stimulation below the fracture.

158
Q

Empyema

A

pus in the pleural cavity due to bacteria spreading from the lung to the pleural space.

159
Q

Angiotensin-converting enzyme (ACE) inhibitors (eg, enalapril)

A

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.

160
Q

Beta blockers (eg, carvedilol)

A

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.

161
Q

Varenicline

167
Q

Sodium nitroprusside

A

a highly potent venous and arterial vasodilator

commonly used in hypertensive emergencies and for conditions in which blood pressure (BP) control is essential (eg, aortic dissection, acute decompensated heart failure)

exert its effects within 1 minute and can produce a sudden and drastic decrease in BP (symptomatic hypotension [eg, light-headedness; cool, clammy skin]). Therefore, the client’s BP should be monitored closely (ie, every 2-5 min)

168
Q

Air embolism after CVC removal or dislodgement

to diagnose and/or treat conditions such as coronary artery disease and heart failure

Contrast dye is injected through a thin, flexible catheter that is inserted through the radial or femoral artery. Images are obtained, and hemodynamic assessments are completed.

Complications- associated with the catheter insertion site:
arterial thrombosis or embolism

frequently assess the affected extremity and report any neurovascular changes (eg, numbness, tingling, decreased pulses, or coolness of the extremity) to the health care provider immediately as blood flow to the extremity may be compromised

It is expected for the pt to feel warm or flushed while the contrast dye is injected.

With diagnostic studies, the client often goes home the same day. Hospitalization is typically only required if angioplasty or stent placement is performed.

General anesthesia is not used during the procedure. Sedatives (eg, midazolam, fentanyl) are administered for client comfort.

172
Q

precipitating factors

A

chest pain brought on by myocardial ischemia (decreased blood flow to the heart muscle

Any factor that increases oxygen demand or decreases oxygen supply to cardiac muscle may cause angina:

Physical exertion (eg, exercise, sexual activity): Increases heart rate and reduces diastole (time of maximum blood flow to the myocardium)
Intense emotion (eg, anxiety, fear): Initiates the sympathetic nervous system and increases cardiac workload
Temperature extremes: Usually cold exposure and hypothermia (vasoconstriction); occasionally hyperthermia (vasodilation and blood pooling)
Tobacco use and second-hand smoke inhalation: Replaces oxygen with carbon monoxide; nicotine causes vasoconstriction and catecholamine release
Stimulants (eg, cocaine, amphetamines): Increase heart rate and cause vasoconstriction
Coronary artery narrowing (eg, atherosclerosis, coronary artery spasm): Decreases blood flow to myocardium

175
Q

Albumin solution (5%)

A

is a colloid that mobilizes fluid from the extravascular tissues into the vascular space. Although it expands intravascular volume, albumin is a second-line therapy in clients with hypotension, low intravascular proteins, and increased fluid in extravascular tissues (eg, cirrhosis with ascites).

176
Q

implantable cardioverter defibrillator (ICD)

if it can’t shock right to correct the dysrythmia, use an AED

A

can sense life-threatening arrhythmia and discharge electrical shocks directly into the cardiac muscle to correct the arrhythmia

Clients typically receive ICDs after a history of sustained or recurrent ventricular tachycardia (VT)

monitor for ICD firings (eg, client report, observation on cardiac monitors). After firings, the nurse should monitor for resolution of the arrythmia, indications of hemodynamic compromise (eg, hypotension, chest pain, altered mentation), and additional ICD discharges.

Occasionally, an ICD may be unable to convert the arrythmia to a hemodynamically stable rhythm and will repeatedly shock the client. If the client experiences repeated ICD shocks without dysrhythmia resolution, the nurse should promptly obtain a manual external defibrillator and initiate measures to prevent hemodynamic instability and cardiac arrest

teaching:
refrain from lifting the affected arm above the shoulder (until approved by the health care provider) to prevent dislodgement of the lead wire on the endocardium
Driving may be approved by the health care provider after healing has occurred
The ICD may set off the metal detector in security areas but. flying is not restricted

Vasospasms-> color change in the appendages (eg, fingers, toes, ears, nose

initially turns white from decreased perfusion, followed by a bluish-purple appearance due to cyanosis, numb, cool

When blood flow is restored, the affected area becomes reddened and clients experience throbbing or aching pain, swelling, and tingling

teaching regarding prevention of vasospasms includes:

Wear gloves when handling cold objects (Option 5).
Dress in warm layers, particularly in cold weather.
Avoid extremes and abrupt changes in temperature.
Avoid vasoconstricting drugs (eg, cocaine, amphetamines, ergotamine, pseudoephedrine).
Avoid excessive caffeine intake
Refrain from use of tobacco products
Implement stress management strategies (eg, yoga, tai chi)
If conservative management is unsuccessful, clients may be prescribed calcium channel blockers to relax arteriole smooth muscle and prevent recurrent episodes.

181
Q

Infective endocarditis (IE)

high risk pts dental prodedure;
congenital heart disease, prosthetic heart valve, recreational IV drug use

A

infection of the innermost layer (ie, endocardium) of the heart +valves

Bacteria adhere to the inner surfaces of the heart and grow into vegetations that can calcify and break off (ie, embolize) to various parts of the body, placing the client at risk for life-threatening complications (eg, pulmonary embolism, stroke).

Splinter hemorrhages (ie, dark, longitudinal streaks under the fingernails) and Janeway lesions (ie, flat, small red spots) on the fingertips, palms, soles, and toes, are common findings in clients with IE due to microemboli in the end-capillaries blocking blood flow. Microemboli should not be prioritized before macroemboli (eg, stroke, ischemic limb).

Treatment of symptomatic sinus bradycardia may include a temporary (eg, transcutaneous or transvenous) or permanent pacemaker.

194
Q

Acute blood loss (eg, gastrointestinal bleeding) is a medical emergency

A

lower the head of the bed (HOB)
supine
elevate legs/feet

-IV fluids -> maintain fluid volume
-monitor hgb, hct -> blood transfusion
-continuous cardiac monitoring
dt risk of dysrythmias dt shock

195
Q

second-degree atrioventricular (AV) block, type 1.

A

an intermittent block usually occurring at the level of the AV node characterized by a progressively lengthening PR interval until a QRS complex is dropped

dt myocardial ischemia (eg, coronary artery disease) or certain medications (eg, beta blockers, digoxin)

First, take VS to check for symptoms of the rhythm
report dizziness, hypotension, SOB

If no symptoms are present, closely monitor the client. If symptoms are present, anticipate using atropine or temporary pacing.

196
Q

Failure to capture

A

pacemaker is firing but the myocardium is not responding with a contraction

It is identified on telemetry by the absence of a P wave or QRS complex following a pacer spike.

Causes include lead dislodgement, battery failure, and inadequate voltage. A malfunctioning pacemaker can cause asystole or serious bradycardia.

If pt is hemodynamically unstable (eg, hypotension, dizzy, short of breath), transcutaneous pacing should be initiated to normalize the heart rate, stabilize blood pressure, and maintain adequate perfusion

(temporary until pacemaker is fixed)

197
Q

cardiac pharmacologic stress test

A

uses vasodilators (eg, adenosine, dipyridamole) to simulate exercise when clients are unable to tolerate continuous physical activity or when their target heart rate is not achieved through exercise alone

Preprocedure instructions:
Avoid smoking cigarettes on the day of the test because nicotine is a stimulant
no coffee,not even decaf
Expect to feel transient nausea and/or flushing as vasodilators are injected
report symptoms such as chest pain and/or dyspnea during the test.
hold beta blockers to ensure accuracy of the test.
A peripheral venous access device will be inserted to administer medications

198
Q

inferior vena cava filter

A

a device that is inserted percutaneously, usually via the femoral vein to trap blood clots from lower extremity vessels

used when clients have recurrent emboli or anticoagulation is contraindicated.

  • Physical activity should be promoted,
  • avoid crossing their legs to promote venous return from the legs
  • Leg pain, numbness, or swelling may indicate impaired neurovascular status distal to the insertion site and should be reported immediately

-S/s of PE (eg, chest pain, shortness of breath) and vascular injury (bleeding causing back pain) are not expected findings after the procedure and should be reported immediately.

199
Q

Treatment for hyperkalemia

A

stabilizes cell membranes:
IV calcium gluconate

excretes k:
IV furosemide

moves K into cells:

albuterol nebulizer
IV insulin with dextrose
