Most common type
Not caused by an existing health problem; can develop when a patient has any one or more of the risk factors:
Lot risk factors

Q

Answer: Additional assessments should include medical history, family history of CV disease, heart and respiratory rate, and medications being taken.
Pulse
Further assessment into edema
Fam history
Smoking, caffeine: additional modifiable risk factors present/not
Meds
Rationale:
Assessing medical and family history provides needed information associated with etiologies and identification of risk factors.
Heart rate and respiratory rates provide information on the effectiveness of tissue perfusion associated with the high blood pressure.
Assessing medication history might lead to the identification of an adverse response.

Q

Answer: Eating a low-sodium diet, limiting his caffeine intake, and quitting smoking. Ask him what a “wholesome meal” is
Eliminating smoking, caffeine, nutrition imp
Limit fast food: cholesterol and sodium
Explore diet habits
Doing right: walking, sleeping well, reading before bed (relaxation), glass (how big) wine not bad, working reasonable amount
Talk about all of this
Rationale:
Sodium increases blood volume, thus increasing blood pressure.
Caffeine and smoking has a vasopressor affect that could increase BP
Recommendations:
Dietary sodium restriction to less than 2 grams; Na restrictions at least less than 2 grams min
Reduce weight
Use alcohol sparingly
Exercise 3-4 days a week for 40 minutes
Use relaxation techniques to decrease stress
Avoid tobacco and caffeine

Q

Reason BP low is because taking med - no symp with HTN because not feel bad most time when not take med
Answer: Hypertension is a chronic illness. Without medication, Mr. Flynn’s hypertension will remain uncontrolled.
A plan should be developed with the patient and ways identified to encourage adherence to his medication regimen.
If the patient is taking beta blockers, suddenly stopping these drugs can result in angina, MI, or rebound hypertension
Med compliance really imp
Quit smoking and did other things might be able go off BP med but per pat; make sure stick on meds and adhering to that
Lot AE not tolerated explore with them on why not want take med; can switch it up because lot meds for them
Rationale:
Some patients may assume that once their blood pressure returns to normal levels, they no longer need treatment.
Side effects can also affect compliance with medication so that should be explored

A

Mr. Flynn returns to his provider’s office for a follow-up. He states that he has been taking his blood pressure every day and that most days it is within the normal range. Mr. Flynn asks the nurse if it is okay to stop his medication? How should the nurse respond to Mr. Flynn?

A. Measure the mass with a ruler
B. Palpate the mass for tenderness
C. Percuss the mass to determine borders

A

What does the nurse suspect is going on with Ms. Adams?

73
Q

Stasis of blood
Vessel wall injury
Altered blood coagulation

A

The nurse knows that there are three major factors involved in the development of DVT. These three factors are referred to as Virchow’s triad and include the following - predisposes to DVT:

74
Q

Which of the medications taken by Mrs. Adams places her at increased risk for the development of DVT?
1. Antibiotics
2. Analgesics
3. Bronchodilator
4. Oral contraceptives

A

Answer: 4
Increases blood coag - hormones
In addition, Mrs. Adam’s age, weight, and recent surgery all increase her risk for the development of DVT. obese higher risk for DVT

75
Q

PREVENTION IS KEY TO ADDRESS THIS CHALLENGE IN HEATLH CARE
Patient education
Leg exercises
Early ambulation
Adequate hydration: Increasing blood volume/circ
Graduated compression stockings
Intermittent pneumatic compression, such as sequential compression devices (SCDs)
Venous plexus foot pump
Avoid oral contraceptives if possible
Anticoagulant therapy - prophylactic dose
Nurse sensitive indicator

A

VTE prevention

76
Q

Which physical assessment should the nurse perform to assist in the diagnosis of suspected DVT?
1. Measure calf circumference bilaterally
2. Observe for excessive bruising
3. Perform test for Homan’s sign
4. Auscultate for bruits

A

Answer: 1
1 - looking for unilateral swelling; Typ not in both legs; Not diagnose but gives clues
2 - not an indic of thrombosis
3 - not a reliable indicator anymore/accurate
4 - would indicate narrowing of artery (stenosis of artery)

77
Q

Focused RR assessments: develop PE: clot moved into pulm vascularture

A

Further assessment of Mrs. Adams by the nurse reveals the following findings:
Swelling, warmth, and mild discomfort of the right calf
Pedal pulses strong (+3/4) bilaterally with capillary refill < 3 seconds
Respirations regular with no dyspnea or cough

Sudden O2 desat
Sharp, stabbing chest pain
Apprehension, restlessness
Feeling of impending doom
Cough
Hemoptysis

A

Signs of PE

79
Q

Movement of clot
Emboli enters venous circulation and lodges in the pulmonary vessels and pulmonary blood flow

A

What is a PE?

80
Q

Reduces gas exchange, reduces oxygenation, pulmonary tissue hypoxia, decreased perfusion, and potential death
It may be the most common preventable death in hospitalized patients but is often misdiagnosed.

A

Emboli enters venous circulation and lodges in the pulmonary vessels and pulmonary blood flow

81
Q

D dimer
Ultrasound

A

What tests diagnose DVT?

82
Q

A negative test can rule out a DVT
A positive test requires further testing to specifically diagnose
not diagnostic; elevated for lot diff reasons; screening

A

D dimer

83
Q

Assesses the flow of blood and is diagnostic of DVT

A

Ultrasound

84
Q

To prevent future thrombi from forming or the extension of the existing thrombus
Heparin IV - know they have a clot
Doing: prevent clot from getting bigger and more clots from forming; clot goes away on own
Weight based; bolus to get therapeutic then start on drip
High risk for bleeding

A

What is the purpose of the anticoagulant?

85
Q

breaks up clot - high risk for bleeding

A

Thrombolytics:

86
Q

It is shift change. The oncoming nurse enters the room and notices observable hematuria in Mrs. Adam’s urinary catheter. What action should the nurse initiate first?
1. Obtain a stat aPTT
2. Stop the heparin infusion
3. Assess vital signs
4. Observe the surgical site for bleeding

A

Answer: 2
Will do all; stop heparin because visible signs of bleeding; heparin likely offending thing; will keep bleeding if not stop infusion

87
Q

After consulting with the HCP, the nurse is to administer a heparin antagonist. Which medication will be administered?
1. Vitamin K
2. Protamine Sulfate
3. Enoxaparin (Lovenox)
4. Ticlopidine (Ticlid)

A

Answer: 2
All anti-coag is antagonist that reverses the effects
Protamine Sulfate is for heparin And LMWH
K - warfarin antagonist
Enoxaparin: LMWH
Ticlopidine: antiplatelet med

88
Q

Heparin
Warfarin (Coumadin)
Enoxaparin (Lovenox)
Other medications are available for clot prevention
Thrombolytics
Surgical management:

A

Meds

89
Q

Lab to check: PTT (at SLHS we use heparin assay)
Antidote: Protamine sulfate
IV to treat/SQ for prevention
Heparin assay better indic how doing; follow rules on how to admin based on lab values - not want be at risk for bleeding/clots; once within therapeutic range - PTT higher because want higher because blood anticoag; never within norm range keep checking q6h; 2 therapeutic assays not go in q6h
SQ - preventative

A

Heparin

90
Q

Lab to check: PT/INR
Antidote: Vitamin K; Given IM
PO
cheap and requires close monitoring of labwork
Prevantative (afib)/know have had a clot
First on it need labs drawn frequently
INR - wherever go numbers same; numbers same regardless of location; 2-3: therapeutic - more anticoag

A

Warfarin (Coumadin)

91
Q

Lab to check: PT/INR (per textbook) and anti-factor Xa assay (at SLHS)
Antidote: Protamine sulfate
Treatment dose; lower dose preventative but also high enough dose
SQ to treat or prevention; often used a bridge with warfarin

A

Enoxaparin (Lovenox)

92
Q

Ex. rivaroxaban (Xarelto); apixaban (Eliquis)
No labs are required
No antidote is available
Expensive
Tons new drugs on market - no reversal for these

A

Other medications are available for clot prevention

93
Q

Tissue plasminogen activators (TPA)
Administered directly into clot through a catheter
Not used often for DVT
High risk for bleeding
Thrombolytics: in IR to bust up clot

A

Thrombolytics

94
Q

Thrombectomy - severe enough to remove clot
Inferior vena cava filtration: IVC filter: stops clot; prevents PE because filtering it: Very common for recurrent DVT if on anticoag therapy or continually developing or too much risk to put on anticoag
