The nurse assesses a client for orthostatic hypotension. The results are: Lying heart rate = 70 beats/minute, BP = 110/70; Sitting heart rate = 78 beats/minute, BP = 106/66; Standing heart rate = 85 beats/minute, BP = 100/64. The nurse would expect which prescription from the primary healthcare provider? Increase furosemide from 20 mg by mouth (PO) to 40 mg PO daily Give 1 L of 0.9% normal saline (NS) bolus over 4 hours Start intravenous (IV) infusion of D5 ½ NS to run at 150 mL/hr No prescription change The nurse is providing postprocedure care to a client who had a cardiac catheterization. The client begins to manifest signs and symptoms associated with embolization. Which action should the nurse take? Notify the primary healthcare provider immediately Apply a warm, moist compress to the incision site Increase the intravenous fluid rate by 20 mL/hr Monitor vital signs more frequently A client who just returned from a cardiac catheterization reports to the nurse that the pressure bandage on the right groin is tight. What action should the nurse take? Loosen the dressing slightly. Notify the primary healthcare provider. Assess the pulses distal to the dressing. Have the client flex the joints of the right leg. A client who is considering sclerotherapy asks the nurse to explain what causes varicose veins. Which response by the nurse is best? "The cause is abnormal configurations of the veins." "The cause is incompetent valves of superficial veins." "The cause is decreased pressure within the deep veins." "The cause is atherosclerotic plaque formation in the veins." A nurse in the postanesthesia care unit is caring for a client who received a general anesthetic. Which finding should the nurse report to the primary healthcare provider? Client pushes the airway out. Client has snoring respirations. Client’s respirations are 16 breaths per minute and unlabored. Client’s systolic blood pressure drops from 130 to 90 mm Hg. A client is admitted to the hospital for an emergency cardiac catheterization. What adaptation is the client most likely to complain of after this procedure? Fear of dying Skipped heartbeats Pain at the insertion site Anxiety in response to intensive monitoring A nurse observes a window washer falling 25 feet (7.6 m) to the ground. The nurse rushes to the scene and determines that the person is in cardiopulmonary arrest. What should the nurse do first? Feel for a pulse Begin chest compressions Leave to call for assistance Perform the abdominal thrust maneuver The nurse at a health fair has taken a client's blood pressure twice, 10 minutes apart, in the same arm while the client is seated. The nurse records the two blood pressures of 172/104 mm Hg and 164/98 mm Hg. What is the appropriate nursing action in response to these readings? Refer the client to a nutritionist after providing health teaching about a low-sodium diet. Place the client in a recumbent position and call the paramedics for transport to the hospital. Talk with the client to assess whether there is stress in the client's life and refer to a counseling service. Take the client's blood pressure in the other arm and then schedule a healthcare practitioner's appointment for as soon as possible. What is the most important nursing action when measuring a client’s pulmonary capillary wedge pressure (PCWP)? Deflate the balloon as soon as the PCWP is measured. Have the client bear down when measuring the PCWP. Place the client in a supine position before measuring the PCWP. Flush the catheter with a heparin solution after the PCWP is determined. When an older client with heart failure is transferred from the emergency department to the medical service, what should the nurse on the unit do first? Interview the client for a health history. Assess the client’s heart and lung sounds. Monitor the client’s pulse and temperature. Obtain the client’s blood specimen for electrolytes. The nurse encourages a client with Raynaud disease to stop smoking. Which primary goal is the nurse trying to achieve? Prevent pain and tingling Prevent cyanosis and necrosis Prevent peripheral vasoconstriction Prevent excessive blood oxygen content A nurse identifies that a client who had a myocardial infarction is struggling with an alteration in self-concept. The nurse intervenes to promote client autonomy. Which behavior by the client demonstrates an increase in client autonomy? Active participation in providing self-care Verbalizing realistic expectations of caregivers Discussing necessary lifestyle changes with family members Listing the indicators of recovery after a myocardial infarction A client has a pulse deficit. Which documentation by the nurse supports this finding? Blood pressure of 130/70 mm Hg indicating pulse deficit of 60. Capillary refill greater than 3 seconds indicating pulse deficit. Apical pulse 86 and radial pulse 78 indicating pulse deficit of 8. Radial pulse 80 and pedal pulse 70 indicating pulse deficit of 10. While caring for a client who had an open reduction and internal fixation of the hip, the nurse encourages active leg and foot exercises of the unaffected leg every 2 hours. What does the nurse explain that these exercises will help to do? Prevent clot formation Reduce leg discomfort Maintain muscle strength Limit venous inflammation After surgery for insertion of a coronary artery bypass graft (CABG), a client develops a temperature of 102° F (38.9° C). Which priority concern related to elevated temperatures does a nurse consider when notifying the healthcare provider about the client's temperature? A fever may lead to diaphoresis. A fever increases the cardiac output. An increased temperature indicates cerebral edema. An increased temperature may be a sign of hemorrhage. A nurse determines that the client’s apical pulse rate is higher than the radial pulse and documents the pulse deficit. What does the nurse consider is the primary reason for the pulse deficit? The client’s heart may be beating faster temporarily. The nurse may not know how to take an accurate pulse. The radial pulse site may be surrounded by too much subcutaneous fat. The client may have atrial fibrillation. A nurse is conducting cholesterol screening for a manufacturing corporation during a health fair. A 50-year-old man who is 6 feet (183 cm) tall and weighs 293 pounds (133 kg) puts out his cigarette and asks the nurse how to modify his risk factors for coronary artery disease. On which risk factors should the nurse help the client focus? Select all that apply. Age Height Weight Smoking Family history A client who was in an automobile collision is now in hypovolemic shock. Why is it important for the nurse to take the client’s vital signs frequently during the compensatory stage of shock? Arteriolar constriction occurs. The cardiac workload decreases. Contractility of the heart decreases. The parasympathetic nervous system is triggered. Two hours after a cardiac catheterization that was accessed through the right femoral route, an adult client complains of numbness and pain in the right foot. What action should the nurse take first? Call the primary healthcare provider. Check the client’s pedal pulses. Take the client’s blood pressure. Recognize the response is expected. A client with a suspected dysrhythmia is to wear a Holter monitor for 24 hours at home. What should the nurse instruct the client to do? Keep a record of the day’s activities. Avoid going through laser-activated doors. Record the pulse and blood pressure every 4 hours. Delay taking prescribed medications until the monitor is removed. A nurse is caring for a client with a diagnosis of polycythemia vera. The client asks, "Why do I have an increased tendency to develop blood clots?" Which effect of the polycythemia vera should the nurse include in the teaching session? Elevated blood pressure Increased blood viscosity Fragility of the blood cells Immaturity of red blood cells The nurse is caring for a client who is receiving a thiazide diuretic for hypertension. Which food selection by the client indicates to the nurse that dietary teaching about thiazide diuretics is successful? Apples Broccoli Cherries Cauliflower The plan of care for a postoperative client who has developed a pulmonary embolus includes monitoring and bed rest. The client asks why all activity is restricted. The nurse’s response should be based on what principle about bed rest? It prevents the further aggregation of platelets. It enhances the peripheral circulation in the deep vessels. It decreases the potential for further dislodgment of emboli. It maximizes the amount of blood available to damaged tissues. The primary healthcare provider prescribes two units of packed red blood cells for a client who is bleeding. Before blood administration, what is the nurse’s priority? Obtaining the client’s vital signs Letting the blood reach room temperature Monitoring the hemoglobin and hematocrit levels Determining proper typing and crossmatching of blood A client with a history of a pulmonary embolus is to receive 3 mg of warfarin daily. The client has blood drawn twice weekly to ascertain that the international normalized ratio (INR) stays within a therapeutic range. The nurse provides dietary teaching. Which food selected by the client indicates that further teaching is necessary? Poached eggs Spinach salad Sweet potatoes Cheese sandwich A nurse is assessing a client’s ECG reading. The client's atrial and ventricular heart rates are equal at 88 beats per min. The PR interval is 0.14 seconds, and the QRS width is 0.10 seconds. Rhythm is regular with normal P waves and QRS complexes. How will the nurse interpret this rhythm? Normal sinus rhythm Sinus tachycardia Sinus bradycardia Sinus arrhythmia A client who had extensive pelvic surgery 24 hours ago becomes cyanotic, is gasping for breath, and reports right-sided chest pain. What should the nurse do first? Obtain vital signs Initiate a cardiac arrest code Administer oxygen using a face mask Encourage the use of an incentive spirometer A Foley catheter was placed with an urimeter for a client with heart failure receiving furosemide. The output is 45 mL/hour, cloudy, and has sediment. How should the nurse interpret these findings? The furosemide is causing dehydration. Cloudy urine may be indicative of infection. The client has inadequate hourly urine output. All of the indications are within normal findings. A client with mild chronic heart failure is to be discharged with prescriptions for daily oral doses of an antidysrhythmic, potassium chloride 40 mEq, docusate sodium 100 mg, and furosemide 40 mg twice a day. The client reports having no family members who can help after discharge. What should the nurse help this client identify? Support systems that can assist the client at home Potential nursing homes in which the client can recuperate Agencies that can help the client regain activities of daily living Ways that the client can develop relationships with neighbors The client is in atrial fibrillation. Which information should the nurse consider about atrial fibrillation when planning care for this client? A loss of atrial kick No physiologic changes Increased cardiac output Decreased risk of pulmonary embolism A nurse is advising a client about the risks associated with failing to seek treatment for acute pharyngitis caused by beta-hemolytic streptococcus. For what health problem is the client at risk? Asthma Anemia Endocarditis Reye syndrome A nurse is collecting data from a client with varicose veins who is to have sclerotherapy. What should the nurse expect the client to report? Feeling of heaviness in both legs Intermittent claudication of the legs Calf pain on dorsiflexion of the foot Hematomas of the lower extremities A client is on a cardiac monitor. The monitor begins to alarm showing ventricular tachycardia. What should the nurse do first? Check for a pulse Start cardiac compressions Prepare to defibrillate the client Administer oxygen via an ambu bag A client with a history of hypertension has a blood pressure of 180/102 mm Hg. When the nurse asks whether the client has been taking any medications, the client replies, "I took the blood pressure pills the healthcare provider prescribed for a few weeks, but I didn't feel any different, so I decided I'd only take them when I feel sick." What is the best initial response by the nurse? "You must be quite frightened about having high blood pressure." "I'm glad to hear you have felt well enough to stop the medication." "It is important to take your medications daily to achieve optimal results." "You will need to document daily whether you took your medication or not. A nurse is assessing a client with the diagnosis of primary hypertension. Which clinical finding does the nurse identify as an indicator of primary hypertension? Mild but persistent depression Transient temporary memory loss Occipital headache in the morning Cardiac palpitation during periods of stress An older client who has had multiple hospital admissions for recurring heart failure is returned to the hospital by an adult child. The client is admitted for observation to the coronary care unit and calmly states, "I know I’m sick, but I can really take care of myself at home." What should the nurse conclude that the client most likely is attempting to do? Suppress fears Deny the illness Maintain independence Reassure the adult child The primary healthcare provider prescribes "bathroom privileges only" for a client with pulmonary edema. The client becomes irritable and asks the nurse whether it is really necessary to stay in bed so much. What would be the best reply by the nurse? "Why do you want to be out of bed?" "Bed rest plays a role in most therapy." "Rest helps your body direct energy toward healing." "Would you like me to ask your primary healthcare provider to change the prescription?" A nurse is providing discharge instructions to a client who experienced an anterior septal myocardial infarction (MI). Which statement by the client indicates the nurse needs to follow up? "I want to stay as pain-free as possible." "I am not good at remembering to take medications." "I should not have any problems in reducing my salt intake." "I wrote down my dietary information for future reference." A woman comes to the office of her healthcare provider reporting shortness of breath and epigastric distress that is not relieved by antacids. To which question would a woman experiencing a myocardial infarction respond differently than a man? "Do you have chest pain?" "Are you feeling anxious?" "Do you have any palpitations?" "Are you feeling short of breath?" A client is admitted to the hospital for a total hip replacement. Included in the primary healthcare provider’s prescriptions is a prescription for digoxin 2.5 mg by mouth daily. The nurse knows that digoxin is supplied in 0.125 mg tablets. What should the nurse do? Give half a tablet. Administer two tablets. Ask the client what dose was taken at home. Verify the prescription with the primary healthcare provider. An electrocardiogram (ECG) is performed before a client is to have a cardiac catheterization, and hypokalemia is suspected. What does the nurse expect the primary healthcare provider to prescribe to confirm the presence of hypokalemia? A complete blood count A serum electrolyte level An arterial blood gas panel An x-ray film of long bones Four days after the client's total hip arthroplasty, the nurse is preparing to transfer the client to a rehabilitation center. Before admission the client took warfarin sodium daily for a history of pulmonary embolus. While hospitalized, the client received subcutaneous heparin two times a day. The nurse does not see any anticoagulant therapy listed on the client's transfer prescriptions. What should the nurse do? Contact the healthcare provider to determine which anticoagulant therapy should be prescribed for this client. Arrange for a supply of heparin for the client to take to the rehab center. Explain to the client that anticoagulant therapy will no longer be needed. Instruct the client to talk about anticoagulant needs with the healthcare provider at the rehabilitation center. Each year, a client takes many trips to other countries. The client reports leg swelling during the long flights. How should the nurse best advise this client when traveling? Relax in a reclining position Sit upright with legs extended Walk around at least every hour Sit in any position that relieves pressure on the legs A client with type 1 diabetes asks what causes the several brown spots on the skin. What would be the best response by the nurse? "The brown spots reflect the accumulation of blood fats in the skin; they should disappear." "Those spots indicate a high glucose content in the skin that may get infected if left untreated." "They are the result of diseased small vessels in the shins and may spread if not treated soon." "Those brown spots result from small blood vessel damage; the blood contains iron, which leaves a brown spot." The nurse is monitoring a client's hemoglobin level. The nurse recalls that the amount of hemoglobin in the blood has what effect on oxygenation status? Except with rare blood disorders, hemoglobin seldom affects oxygenation status. There are many other factors that affect oxygenation status more than hemoglobin does. A low hemoglobin level causes reduced oxygen-carrying capacity. Hemoglobin reflects the body's clotting ability and may or may not affect oxygenation status. What should the nurse teach a client who is taking antihypertensives to do to minimize orthostatic hypotension? Wear support hose continuously. Lie down for 30 minutes after taking medication. Avoid tasks that require high-energy expenditure. Sit on the edge of the bed for 5 minutes before standing. What should the nurse do to prevent thrombus formation after most surgeries? Keep the client’s bed gatched to elevate the knees. Have the client dangle the legs off the side of the bed. Have the client use an incentive sp
