1. The ankle edema suggests fl uid volume overload. The nurse should assess respiratory rate, lung sounds, and SpO2 to identify any signs of respiratory symptoms of heart failure requiring immediate attention.

3. Heart failure is a complex and chronic condition. Education should focus on health promo- tion and preventive care in the home environment.

Signs and symptoms can be monitored by the client.

Instructing the client to obtain daily weights at the same time each day is very important. The client should be told to call the physician if there has been a weight gain of 2 lb or more. This may indicate fl uid overload, and treatment can be prescribed early and on an outpatient basis, rather than wait- ing until the symptoms become life-threatening.

Following a high-fi ber diet is benefi cial, but it is not relevant to the teaching needs of the client with heart failure. Prescribing an exercise program for the client, such as walking 2 miles every day, would not be appropriate at discharge. The client’s exercise program would need to be planned in consultation with the physician and based on the history and the physical condition of the client. The client may require exercise tolerance testing before an exercise plan is laid out. Although the nurse does not pre- scribe an exercise program for the client, a sedentary lifestyle should not be recommended.

Episodic prophylaxis is required to prevent infective endocarditis after dental procedures or upper respiratory, gastrointestinal, or genitourinary tract surgery. Diet modifi cation, activity restrictions, and dental care are important; however, they do not have as much signifi cance postoperatively as medi- cation therapy does.

4. Management of postoperative pain is a priority for the client after surgery, including valve replacement surgery, according to the Agency for Health Care Policy and Research. The client and family should be informed that pain will be assessed by the nurse and medications will be given to relieve the pain. The client will stay in the ICU as long as monitoring and intensive care are needed.

Sensory deprivation and overload, high noise levels, and disrupted sleep and rest patterns are some envi- ronmental factors that affect recovery from valve replaceent surgery.

2, 3, 4. The hemoglobin and hematocrit should be assessed to evaluate blood loss. An elevated INR & PTT and decreased platelet count increase the risk for bleeding. The client may require blood products depending on lab values and sever- ity of bleeding, therefore availability of blood prod- ucts should be confi rmed by calling the blood bank.

Close monitoring of blood loss from the mediastinal chest tubes should be done. Coumadin is an antico- agulant that will increase bleeding. Anticoagulation should be held at this time. Information is needed on the type of valve replacement. For a mechani- cal heart valve, the INR is kept at 2 to 3.5. Tissue valves do not require anticoagulation. Dopamine should NOT be initiated if the client is hypotensive from hypovolemia. Fluid volume assessment should always be done fi rst. Volume replacement should be initiated in a hypovolemic client prior to starting an inotrope such as dopamine.

Many factors help prevent wound infec- tions, including washing hands carefully, using sterile prepackaged supplies and equipment, clean- ing the incisional area well, and disposing of soiled dressings properly. However, most authorities say that the single most effective measure in prevent- ing wound infections is to wash the hands care- fully before and after changing dressings. Careful hand washing is also important in reducing other

For clients scheduled for a cardiac catheterization it is important to assess for iodine sensitivity, verify written consent, and instruct the client to take nothing by mouth for 6 to 18 hours before the procedure. Oral medications are with- held unless specifi cally ordered. A urinary drainage catheter is rarely required for this procedure.

2. The nurse should immediately assess the blood pressure since Nipride and Lasix can cause severe hypotension from a decrease in preload and afterload. If the client is hypotensive, the Nipride dose should be reduced or discontinued. Urine output should then be monitored to make sure there is adequate renal perfusion. A 12-lead EKG is per- formed if the client experiences chest pain. A reduc- tion in pulmonary artery pressures should improve the pulmonary congestion and lung sounds.

1. In an immobilized client, calcium leaves the bone and concentrates in the extracellular fl uid.

When a large amount of calcium passes through the kidneys, calcium can precipitate and form calculi.

Nursing interventions that help prevent calculi include ensuring a liberal fl uid intake (unless con- traindicated). A diet rich in acid should be provided to keep the urine acidic, which increases the solu- bility of calcium. Preventing constipation is not associated with excessive calcium excretion. Limit- ing foods rich in calcium, such as dairy products, will help in preventing renal calculi.

3. INR is the value used to assess effective- ness of the warfarin sodium therapy. INR is the prothrombin time ratio that would be obtained if the thromboplastin reagent from the World Health Organization was used for the plasma test. It is now the recommended method to monitor effectiveness of warfarin sodium. Generally, the INR for clients administered warfarin sodium should range from 2 to 3. In the past, prothrombin time was used to assess effectiveness of warfarin sodium and was maintained at 1.5 to 2.5 times the control value. Partial throm- boplastin time is used to assess the effectiveness of heparin therapy. Fresh frozen plasma or vitamin K is used to reverse warfarin sodium’s anticoagulant effect, whereas protamine sulfate reverses the effects of hepa- rin. Warfarin sodium will help to prevent blood clots.

Activities should be gradually resumed on discharge.

3. Compliance is the most critical element of hypertension therapy. In most cases, hypertensive clients require lifelong treatment and their hyper- tension cannot be managed successfully without drug therapy. Stress management is an important component of hypertension therapy, but the prior- ity goal is related to compliance. It is not necessary for the client to change jobs or retire, but rather to learn to manage stress if the job is stressful. Los- ing weight may be necessary and will contribute to lower blood pressure, but the client must fi rst accept the need for a lifelong management plan to control the hypertension.

4. Possible dizziness from orthostatic hypotension when rising from a crouched or bent position increases the client’s risk of being injured by the equipment.

The client may experience muscle aches, or thirst from work- ing in a warm, dry room, but these are not as poten- tially dangerous as orthostatic hypotension. The client should not be experiencing lethargy.

Each paddle is placed directly on the conductive pads that are on the client’s skin.

Applying approximately 20 to 25 lb of pressure on each paddle is recommended to ensure good skin contact. The nurse must record the amount of elec- trical current delivered and the resulting rhythm.

Skin integrity, while important, is not an immediate concern. The pacemaker is used to increase heart rate and cardiac output, not decrease it. The client should limit activity for the fi rst 24 to 48 hours after pacemaker insertion. The client should also restrict movement of the affected extremity for 24 hours.

The client will not necessar- ily be placed on a low cholesterol diet. The client should resume activities as he is able, and does not need to remain on bed rest. The client should know signs and symptoms of MI, but is not at risk because of the pacemaker.
