The nurse in the cardiology clinic is reviewing teaching about hypertension, provided at the client's last appointment. Which actions by the client indicate that teaching has been effective?
Teaching about hypertension has been effective when the nurse notes that the client has been on a low-sodium, no-added salt diet, has lost 3 pounds (1.4 kg) since the last clinic visit, and has cut down on caffeine. Clients with hypertension need to consume low-sodium foods and would avoid adding salt. Weight loss can result in lower blood pressure. Caffeine promotes vasoconstriction, thereby elevating blood pressure
The nurse is teaching a client the precautions to take while on warfarin (Coumadin) therapy. Which statement made by the client demonstrates that teaching has been effective?
Teaching about the precautions of warfarin has been effective when the client says "that eating foods like green beans won't interfere with my Coumadin therapy." Vitamin K is not found in foods such as green beans, so these foods will not interfere with the anticoagulant effects of Coumadin.Warfarin
The nurse is caring for a client with dark-colored toe ulcers and blood pressure (BP) of 190/100 mm Hg. Which nursing action does the nurse delegate to the LPN/LVN?
The action the nurse delegates to the LPN/LVN caring for a client with dark-colored toe ulcers and a BP of 190/100 mmHg is to administer a clonidine patch for hypertension. Administering medication is within the scope of practice for the LPN/LVN.The RN is responsible for physical assessments, making referrals for other services, and developing the plan of care for the hospitalized client.
The nurse is assigned to all of these clients. Which client would be assessed first?

A client is receiving unfractionated heparin (UFH) by infusion. Of which finding does the nurse notify the primary health care provider (PCP)?
When caring for a client receiving UFH, the nurse notifies the PCP of a platelet level of 32,000/mm3 (32 × 109/L). UFH can decrease platelet counts. The PCP must be notified if the platelet count is below 100,000 to 120,000/mm3 (100 to 120 × 109/L). Heparin-induced thrombocytopenia, an immune disorder, presents with platelets less than 150,000/mm3 (150 × 109/L)

Chronic PAD stage 2
claudication
Which symptom reported by a client who has had a total hip replacement requires emergency action?
client reports shortness of breath and cheat pain. Shortness of breath and chest pain indicate a possible pulmonary embolism (PE), which can be life threatening. Orthopedic procedures create high risk for deep vein thrombosis (DVT) and PE

essential hypertension
Psychiatric disturbance can exacerbate
essential hypertension

include LDL-C of 160 mg/dL (4.14 mmol/L), smoking, and type 2 diabetes.
The nurse suspects that a client has developed an acute arterial occlusion of the right lower extremity based on which signs/symptoms?
include cold right foot, numbness and tingling of the right foot, and mottling and tingling of the right foot. Pain, pallor, pulselessness, paresthesia, paralysis, poikilothermia (cool limb), and mottled color are characteristics of acute arterial occlusion
Homocysteine
increase levels permit plague build up
Leg swelling may be related to
injury and thromboembolism.
Cereals are fortified with
iron
Absence of pulse, rather than bounding pulse
is a symptom of acute arterial occlusion.
LDL-C of 160 mg/dL (4.14 mmol/L)
is advised to modify diet and exercise. Smoking is a modifiable risk factor and needs to be avoided or terminated. Diabetes is a risk factor for atherosclerotic disease.ASA (asprin) is used as prophylaxis for atherosclerotic disease/coronary artery disease to prevent platelet adhesion. A diet high in whole grains, fruits, and vegetables is desirable to prevent atherosclerosis. Vegetarians usually consume fruits, vegetables, and nonanimal sources of protein.
LDL-C 130 to 159 mg/dL (3.37 to 4.12 mmol/L)
is borderline high.
100 to 129 mg/dL (2.59 to 3.34 mmol/L)
is near or less than optimal.
Having an LDL-C value of less than 100 mg/dL (2.59 mmol/L)
is optimal
A client has undergone an embolectomy for acute arterial occlusion after creation of a lower arm arteriovenous fistula for dialysis. Which finding does the nurse report to the primary health care provider (PCP) immediately?
is swelling and tenseness in the affected arm. Compartment syndrome may develop after an embolectomy, with swelling of skeletal muscle fibers causes increasing pain, swelling, and tenseness. A fasciotomy may be needed to preserve the limb
A client with peripheral arterial disease (PAD) has undergone percutaneous transluminal angioplasty (PTA) of the lower extremity. What is essential for the nurse to assess after the procedure?
it is essential for the nurse to assess for pedal pulses. Priority nursing care focuses on assessment for bleeding at the arterial puncture site and monitoring distal pulses to ensure adequate perfusion.

Chronic high BP (hypertension ) left untreated can lead to:
stroke, blood vessel damage (arteriosclerosis) MI, or heart failure, Kidney failure
questionable assignment made by the charge nurse is assigning the LPN/LVN with 20 years' experience to care for a client with a headache whose BP is 210/150 mm Hg. The client with a headache and high blood pressure has unstable hypertension and is at risk for complications such as
stroke, heart failure, or renal failure. This client must be assigned to an experienced RN, who can assess for end-organ damage and administer IV medications
Vascular changes that occur during acute raynaud's disease
the arteries constrict and prevent blood flow to the fingertips. The insufficient blood flow results in hypermia followed by pallor and cyanosis. Other areas that can be affected in acute attack are the toes, nose, ears, lips, and nipples
Malignant hypertension
the most lethal form of hypertension. It is a fulminating condition characterized by severely elevated bp that commonly damages the intima of small vessels, the brain, the retina, the heart, and the kidneys. Many patients with this condition exhibit signs of hypokalemia and alkalosis and have aldosterone secretion rates even higher than those associated with primary aldosteronism.
Which teaching point does the nurse include for a client with peripheral arterial disease (PAD)?
the nurse include for a client to walk to the point of leg pain, rest, and then resume when pain stops. Exercise may improve arterial blood flow by building collateral circulation. Instruct the client to walk until the point of claudication, stop and rest, and then walk a little farther.
A client's medical record shows these data:Physical Assessment FindingsDiagnostic Findings Provider PrescriptionsCrackles at basesPTT 55 secondsLovenox 40 mg twice dailyRight leg swellingPOSITIVE, D-dimerElevate right legRight calf painhCG negativeDoppler study right leg
the presence of thromboembolism is positive D-dimer (>0.5mg/L). A D-dimer test is a global marker of coagulation activation, and measures fibrin degradation products produced from fibrinolysis (clot breakdown). The test is often used for the diagnosis of deep vein thrombosis when the client has few clinical signs, and stratifies clients into a high-risk category for reoccurrence
