The nurse concludes that teaching about pain management was effective when the client states:

"I will support my incision with my hands when I do my coughing and deep breathing exercises." Splinting of the incision provides support to the incision and helps to control pain.

Adequate hourly urine output for a client with an indwelling urinary catheter is

2.0 mL/kg/h. If the client has an indwelling urinary catheter, output is monitored hourly and rates <0.5 mL/kg/h are reported.

A physically fit 86-year-old is scheduled for right knee replacement. What factor in this client makes them at increased risk for surgery?

Age

Which of the following is a diagnostic test that involves injection of a contrast media into the venous system through a dorsal vein in the foot?

Contrast phlebography When a thrombus exists, an X-ray image will disclose an unfilled segment of a vein. Air plethysmography quantifies venous reflux and calf muscle pump ejection. In lymphangiography, contrast media are injected into the lymph system. In lymphoscintigraphy, a radioactive-labeled colloid is injected into the lymph system.

A patient who had a colon resection 3 days ago is complaining of discomfort in the left calf. How should the nurse assess Homan's sign to determine if the patient may have a thrombus formation in the leg?

Dorsiflex the foot while the leg is elevated to check for calf pain. Homan's sign is indicated by pain in the calf after the foot is sharply dorsiflexed.

A client with venous insufficiency asks the nurse what they can do to decrease their risk of complications. What advice should the nurse provide to clients with venous insufficiency?

Elevate the legs periodically for at least 15 to 20 minutes. The nurse should advise the client to periodically elevate the legs for at least 15 to 20 minutes. Avoiding foods with iodine or refraining from sexual activity for a week does not relate to venous insufficiency.

A gunshot wound would be classified under which category of surgery based on urgency?

Emergent

Which statement is accurate regarding Reynaud disease?

Episodes may be triggered by unusual sensitivity to cold. Episodes of Reynaud disease may be triggered by emotional factors or by unusual sensitivity to cold. The disease is most common in women between 16 and 40 years of age. It is generally unilateral and affects only one or two digits.

A client with a diagnosed abdominal aortic aneurysm (AAA) develops severe lower back pain. Which is the most likely cause?

The aneurysm may be preparing to rupture. Signs of impending rupture include severe back or abdominal pain, which may be persistent or intermittent. Abdominal pain is often localized to the middle or lower abdomen to the left of the midline. Low-back pain may be present because of pressure of the aneurysm on the lumbar nerves. Indications of a rupturing AAA include constant, intense back pain; falling blood pressure; and decreasing hematocrit. Rupture into the peritoneal cavity is quickly fatal. A retroperitoneal rupture of an aneurysm may result in hematomas in the scrotum, perineum, flank, or penis.

The nurse is caring for the client in the preoperative period and documenting rationale for a palliative surgical procedure. Which rationale is most appropriate?

The client and physician are focusing on symptom relief not a cure.

A nurse is teaching a client with chronic bronchitis about breathing exercises. Which instruction should the nurse include in the teaching?

Use diaphragmatic breathing.

A 17-year-old client is having same-day surgery. Solely during the intraoperative phase of perioperative care, the nurse:

continuously monitors the sedated client.

What is the best response by the nurse when the patient states, "I'm so nervous about my surgery"?

"Would you like to discuss the concerns that you have?" People express fear in different ways. Some patients may ask repeated questions, regardless of information already shared with them. Others may withdraw, deliberately avoiding communication by reading, watching television, or talking about trivialities. Consequently, the nurse must be empathetic, listen well, and provide information that helps alleviate concerns.

A patient having a surgical procedure takes aspirin 325 mg daily for prevention of platelet aggregation. When should the patient stop taking the aspirin before the surgery?

7 to 10 days

As the clinic nurse caring for a client with varicose veins, what is an appropriate nursing action for this client?

Demonstrate how to apply and remove elastic support stockings. The nurse demonstrates how to apply and remove elastic support stockings. Varicose veins do not require the nurse to demonstrate how to self-administer IV infusions. Varicose veins require the client to elevate legs regularly and perform leg exercises. However, it does not involve bleeding or skin lesions.

Which is a characteristic of arterial insufficiency?

Diminished or absent pulses A diminished or absent pulse is a characteristic of arterial insufficiency. Venous characteristics include superficial ulcer formation, an aching and cramping pain, and presence of pulses.

Which of the following therapies are for patient who have advanced heart failure (HF) after all other therapies have failed?

Heart transplant Heart transplantation involves replacing a person's diseased heart with a donor heart. This is an option for advanced HF patients when all other therapies have failed. A ventricular access device, ICD, and cardiac resynchronization therapy would be tried prior to a heart transplant.

The nurse is conducting a health history of a preoperative client. The client shares that she experienced vaginal itching and burning and labial swelling after her partner tried a new brand of condoms. The nurse suspects that the client:

May have a latex allergy. Most condoms are made of latex. The client who experiences itching, swelling, hives, or other symptoms after contact with a condom may have a latex allergy.

Which risk factor is related to venous stasis for deep vein thrombosis (DVT) and pulmonary embolism (PE)?

Obesity Obesity is a risk factor for DVT and PE related to venous stasis. Trauma, pacing wires, and surgery are related to endothelial damage as a risk factor for DCAT and PE.

Which is a risk factor for venous disorders of the lower extremities?

Obesity Careful assessment is invaluable in detecting early signs of venous disorders of the lower extremities. Clients with a history of varicose veins, hypercoagulation, neoplastic disease, cardiovascular disease, or recent major surgery or injury are at high risk. Other clients at high risk include those who are obese or older adults and women taking oral contraceptives.

The nurse is caring for the postoperative client in the postanesthesia care unit. Which of the following is the priority nursing action?

Position the client to maintain a patent airway. Maintaining a patent airway is the immediate priority in the PACU.

The nurse observes that a postsurgical client has hemorrhaged and is in hypovolemic shock. Which nursing intervention will manage and minimize hemorrhage and shock?

Reinforcing dressings or applying pressure if bleeding is frank The nurse should reinforce the dressing or apply pressure if bleeding is frank. The nurse should keep the head of the bed flat unless it is contraindicated. Encouraging the client to breathe deeply and rubbing the back will not help manage and minimize hemorrhage and shock.

A postoperative client is being evaluated for discharge and currently has an Aldrete score of 8. Which of the following is the most likely outcome for this client?

The client can be discharged from the PACU. The Aldrete score is usually 8 to 10 before discharge from the PACU. Clients with a score of less than 7 must remain in the PACU until their condition improves or they are transferred to an intensive care area, depending on their preoperative baseline score.

A client with no known history of peripheral vascular disease comes to the emergency department complaining of sudden onset of lower leg pain. Inspection and palpation reveal absent pulses; paresthesia; and a mottled, cyanotic, cold, and cadaverous left calf. While the physician determines the appropriate therapy, the nurse should

keep the affected leg level or slightly dependent. While the physician makes treatment decisions, the nurse should maintain the client on bed rest, keeping the affected leg level or slightly dependent (to aid circulation) and protecting it from pressure and other trauma. Warming the leg with a heating pad (or chilling it with an ice pack) would further compromise tissue perfusion and increase injury to the leg. Elevating the leg would worsen tissue ischemia. Shaving an ischemic leg could cause accidental trauma from cuts or nicks.

For the client who is taking aspirin, it is important to stop taking this medication at least how many day(s) before surgery?

7

A patient is admitted to a special critical care unit for the treatment of an arterial thrombus. The nurse is aware that the preferred drug of choice for clot removal, unless contraindicated, would be:

Alteplase Alteplase has fewer disadvantages than the other thrombolytic agents. Refer to Table 18-2 in the text.

An anxious client being prepared for surgery is encouraged to concentrate on a pleasant experience or restful scene. What cognitive coping strategy would the nurse document as being used?

Imagery Imagery has proven effective for anxiety in surgical clients. Optimistic self-recitation is practiced when the client recites optimistic thoughts such as, "I know all will go well." Distraction is used when the client is encouraged to think of an enjoyable story or recite a favorite poem. Progressive muscular relaxation requires contracting and relaxing muscle groups and is a physical coping strategy as opposed to a cognitive strategy.

Which of the following is the hallmark symptom for peripheral arterial disease (PAD) in the lower extremity?

Intermittent claudication

The nurse is conducting a preoperative assessment on a client scheduled for gallbladder surgery. The client reports a frequent cough producing green sputum for 3 days and denies fever. Upon auscultation, the nurse notes rhonchi throughout the right lung, with an occasional expiratory wheeze. Respiratory rate is 20, temperature is 99.8 (taken orally), heart rate is 87, and blood pressure is 124/70. What is the best action by the nurse?

Notify the surgeon to possibly delay the surgery.

The nurse documents the presence of granulation tissue in a healing wound. How should the nurse describe the tissue?

Pink to red and soft, bleeding easily In second-intention healing, necrotic material gradually disintegrates and escapes, and the abscess cavity fills with a red, soft, sensitive tissue that bleeds easily. This tissue is composed of minute, thin-walled capillaries and buds that later form connective tissue. These buds, called granulations, enlarge until they fill the area left by the destroyed tissue.

When is the ideal time to discuss preoperative teaching

Preadmission visit The ideal timing for preoperative teaching is not on the day of surgery but during the preadmission visit, when diagnostic tests are performed. Teaching should be done long before the patient enters the preop area. Preoperative teaching should not be done when the patient is sedated.

Once the operating team has assembled in the room, the circulating nurse calls for a "time out." What action should the nurse take during the time out?

Review the scheduled procedure, site, and client. According to the 2009 National Patient Safety Goals, accurate identification of the client, procedure, and operative site is essential.

What should the nurse do to manage persistent swelling in a client with severe lymphangitis and lymphadenitis?

Teach the client how to apply a graduated compression stocking. In severe cases of lymphangitis and lymphadenitis with persistent swelling, the nurse teaches the client how to apply a graduated compression stocking. The nurse informs the physician if the client's temperature remains elevated. The nurse recommends elevating the area to reduce the swelling and provides warmth to promote comfort and to enhance circulation.

The nurse discovers that the client did not sign the operative consent before receiving the preoperative medication. The appropriate nursing action is:

To notify the surgeon

A patient is suspected to have a thoracic aortic aneurysm. What diagnostic test(s) does the nurse anticipate preparing the patient for? (Select all that apply.)

Transesophageal echocardiography X-ray Computed tomography Diagnosis of a thoracic aortic aneurysm is principally made by chest x-ray, computed tomography angiography (CTA), and transesophageal echocardiography (TEE).

The nurse teaches the client with peripheral vascular disease (PVD) to refrain from smoking because nicotine

causes vasospasm Nicotine causes vasospasm and can thereby dramatically reduce circulation to the extremities. Nicotine has stimulant effects. Nicotine does not suppress cough; rather, smoking irritates the bronchial tree, causing coughing. Nicotine does not cause diuresis.

You are the nurse working in an ambulatory surgery center. A teenage son of your clients ask you why so many people have surgery. What would be your best reply?

"Many people have diagnostic or short therapeutic surgical procedures." Many diagnostic or short therapeutic surgical procedures—such as bone marrow biopsy, endoscopy, or cardiac catheterization—are now performed in outpatient settings and ambulatory surgical centers. Options B, C, and D seem to minimize the teenager's question.

The nurse is assessing a hospital client who has low albumin levels due to liver disease. What assessment finding should the nurse attribute to the client's low albumin levels?

There is severe edema to the client's legs and abdomen. Albumin helps to keep fluids within the vascular space. Deficiencies, as a result, cause the release of fluid into interstitial spaces, causing edema. Hypoalbuminemia does not cause excessive bleeding, reduced energy or respiratory difficulties.

Using the PACU room scoring guide, a nurse would give a patient an admission cardiovascular score of 2 if the patient's blood pressure is what percentage of his or her preanesthetic level?

20% The patient would receive a cardiovascular/circulation score of 2 if the blood pressure is 20% of the preanesthetic level.

What abnormal postoperative urinary output should the nurse report to the physician for a 2-hour period?

<30 mL If the patient has an indwelling urinary catheter, hourly outputs are monitored and rates of less than 30 mL per hour are reported; if the patient is voiding, an output of less than 240 mL per 8-hour shift is reported.

The Cardiac Nurse Clinician is teaching a group of clients with heart failure about self-management of their disease. What dietary advice should the Nurse Clinician give to clients with severe heart failure until edema resolves?

Avoid the intake of processed and commercially prepared foods. Until edema resolves, a client with severe heart failure requires restriction of sodium to 500 to 1,000 mg/day. Therefore, processed and commercially prepared foods are eliminated. Vegetables with natural sodium, for example, beets, carrots, and "greens," should be avoided. Fresh, frozen, and canned fruit and fruit juices are not restricted. Increased intake of red meat should not be encouraged; it should be restricted to 6 oz per day.

A patient in severe pulmonary edema is being intubated by the respiratory therapist. What priority action by the nurse will assist in the confirmation of tube placement in the proper position in the trachea?

Call for a chest x-ray. A chest x-ray is always obtained after ET tube placement to confirm that the tube is in the proper position within the trachea.

The client asks the nurse about ways to control pain other than taking pain medication. Which strategy should the nurse include when responding to the client? Select all that apply.

Changing position Listening to music Watching television Nonpharmacological management of pain includes listening to music, watching television, and changing position. Pharmacological pain management strategies include epidural infusions and On-Q pumps. An epidural infusion delivers a local opioid with or without a local anesthetic agent directly into the epidural space of the spine. An On-Q pump delivers a local anesthetic agent subcutaneously to the incisional area.

The nurse assesses a patient with hip pain related to intermittent claudication. She knows that the area of arterial narrowing is the:

Common iliac artery. The location of the claudication occurs in muscle groups distal to the diseased vessel. Hip or buttock pain may result from reduced blood flow from the common iliac artery.

A nurse is caring for a client in the PACU after surgery requiring general anesthesia. The client tells the nurse, "I think I'm going to be sick." What is the primary action taken by the nurse?

Position the client in the side-lying position. The primary action taken by the nurse should be to position the client in the side-lying position in order to prevent aspiration of stomach contents if the client vomits. The nurse may also obtain an emesis basin and administered an anti-emetic if one is ordered; however, these will be done after the client is repositioned. There is no need for the nurse to ask the client for more clarification.

A nurse should be prepared to manage complications following abdominal aortic aneurysm resection. Which complication is most common?

Renal failure Renal failure commonly occurs if clamping time is prolonged, cutting off the blood supply to the kidneys. Hemorrhage and shock are the most common complications before abdominal aortic aneurysm resection, and they occur if the aneurysm leaks or ruptures. Graft occlusion and enteric fistula formation are rare complications of abdominal aortic aneurysm repair.

A surgical client has been transferred to the holding area. What nursing intervention(s) promote safe and effective nursing care? Select all that apply.

Review the medical records. Verify the surgical site and mark it appropriately. Identify the client using two identifiers.

When does the nurse understand the patient is knowledgeable about the impending surgical procedure?

The patient participates willingly in the preoperative preparation. The nurse knows that the patient understands the surgical intervention when the patient participates in preoperative preparation. The other answers pertain to the patient experiencing decreased fear or anxiety, not knowledge about the procedure.

The nurse is teaching the client about patient-controlled analgesia. Which of the following would be appropriate for the nurse to include in the teaching plan?

Therapeutic drug levels can be maintained more evenly with patient-controlled analgesia. Advantages of patient-controlled analgesia include participation of the client in care, elimination of delayed administration of analgesics, and maintenance of therapeutic drug levels. The client must have the cognitive and physical abilities to self-dose.

At what point does the preoperative period end?

When the client is transferred onto the operating table

A client asks why a drain is in place to pull fluid from the surgical wound. What is the best response by the nurse?

"It assists in preventing infection." A wound drain assists in preventing infection by removing the medium in which bacteria could grow. The purpose of the wound drain is not to remove necrotic tissue or to decrease the number of dressing changes. Stating that most surgeons use wound drains does not answer the client's question appropriately.

What does the nurse recognize as one of the most common postoperative respiratory complications in elderly patients?

Pneumonia Older patients recover more slowly, have longer hospital stays, and are at greater risk for development of postoperative complications. Delirium, pneumonia, decline in functional ability, exacerbation of comorbid conditions, pressure ulcers, decreased oral intake, GI disturbance, and falls are all threats to recovery in the older adult (Tabloski, 2009; Tolson, Morley, Rolland, et al., 2011).

The nurse has provided preoperative instructions to a client scheduled for surgery at an ambulatory care center. Which statement, made by the client, would indicate that further instruction is needed?

"The nurse will explain the details of the surgery before I sign a consent." Further instruction would be needed to clarify that the physician, not the nurse, explains the details of the surgery and obtains voluntary consent for the procedure. It is correct that preoperative instructions must be followed prior to surgery for the safety of the client, medical records are present for review prior to surgery, and the physician speaks with the family following the procedure and provides instructions for discharge.

The nurse is monitoring a patient who is on heparin anticoagulant therapy. What should the nurse determine the therapeutic range of the international normalized ratio (INR) should be?

2.0-3.0 Oral anticoagulants, such as warfarin, are monitored by the PT or the INR. Because the full anticoagulant effect of warfarin is delayed for 3 to 5 days, it is usually administered concurrently with heparin until desired anticoagulation has been achieved (i.e., when the PT is 1.5 to 2 times normal or the INR is 2.0 to 3.0) (Holbrook et al., 2012).

In a client with a bypass graft, the distal outflow vessel must have at least what percentage patency for the graft to remain patent?

50 The distal outflow vessel must be at least 50% patent for the graft to remain patent.

A nursing instructor is discussing the diagnosis of intermittent claudication with students. To determine whether the students understand the pathophysiology of the disease, the instructor asks, "What percentage of the arterial lumen must be obstructed before intermittent claudication is experienced?" What answer should the students give?

50 Typically, about 50% of the arterial lumen or 75% of the cross-sectional area must be obstructed before intermittent claudication is experienced.

A client has had an echocardiogram to measure ejection fracton. The nurse explains that ejection fraction is the percentage of blood the left ventricle ejects upon contraction. What is the typical percentage of blood a healthy heart ejects?

55% Normally, a healthy heart ejects 55% or more of the blood that fills the left ventricle during diastole.

The nurse is preparing to discharge a patient from the PACU using a PACU room scoring guide. With what score can the patient be transferred out of the recovery room?

8 Many hospitals use a scoring system (e.g., Aldrete score) to determine the patient's general condition and readiness for transfer from the PACU (Aldrete & Wright, 1992). Throughout the recovery period, the patient's physical signs are observed and evaluated by means of a scoring system based on a set of objective criteria. This evaluation guide allows an objective assessment of the patient's condition in the PACU (Fig. 19-3). The patient is assessed at regular intervals, and a total score is calculated and recorded on the assessment record. The Aldrete score is usually between 8 and 10 before discharge from the PACU.

What is the blood glucose level goal for a diabetic patient who will be having a surgical procedure?

80 to 110 mg/dL Although the surgical risk in the patient with controlled diabetes is no greater than in the patient without diabetes, strict glycemic control (80 to 110 mg/dL) leads to better outcomes (Alvarex et al., 2010). Frequent monitoring of blood glucose levels is important before, during, and after surgery.

The nurse expects informed consent to be obtained for insertion of:

A gastrostomy tube

The on-call perioperative team is called for an urgent surgery to be performed as soon as they arrive. What surgical procedure is considered emergent?

A repair of multiple stab wounds

What measurement should the nurse report to the physician in the immediate postoperative period?

A systolic blood pressure lower than 90 mm Hg A systolic blood pressure of less than 90 mm Hg is usually considered immediately reportable. However, the patient's preoperative or baseline blood pressure is used to make informed postoperative comparisons. A previously stable blood pressure that shows a downward trend of 5 mm Hg at each 15-minute reading should also be reported. The other findings are normal or close to normal.

A physician's admitting note lists a wound as healing by second intention. What does the nurse expect to find?

A wound in which the edges were not approximated Second-intention healing (granulation) occurs in infected wounds (abscess) or in wounds in which the edges have not been approximated.

The nurse is concerned that a postoperative patient may have a paralytic ileus. What assessment data may indicate that the patient does have a paralytic ileus?

Absence of peristalsis Paralytic ileus and intestinal obstruction are potential postoperative complications that occur more frequently in patients undergoing intestinal or abdominal surgery. Manipulation of the abdominal organs during surgery may produce a loss of normal peristalsis for 24 to 48 hours, depending on the type and extent of surgery.

You are caring for a client with left-sided heart failure. When you go in to do your shift assessment, you find your client is wheezing, restless, tachycardic, and has severe apprehension. You know that these are symptoms of what?

Acute pulmonary edema Clients with acute pulmonary edema exhibit sudden dyspnea, wheezing, orthopnea, restlessness, cough (often productive of pink, frothy sputum), cyanosis, tachycardia, and severe apprehension. These symptoms do not indicate progressive heart failure, pulmonary hypertension, or cardiogenic shock.

Clients who have received corticosteroids preoperatively are at risk for which type of insufficiency?

Adrenal Clients who have received corticosteroids are at risk of adrenal insufficiency. Insufficiency related to corticosteroids does not occur in the pituitary, thyroid, or parathyroid glands.

A client refuses to remove her wedding band when preparing for surgery. What is the best action for the nurse to take?

Allow the client to wear the ring and cover it with tape.

A client refuses to remove her wedding band when preparing for surgery. What is the best action for the nurse to take?

Allow the client to wear the ring and cover it with tape. Most facilities will allow a client to wear a wedding band during a surgical procedure. The nurse must secure the ring with tape. Although it is appropriate to discuss the risk for infection, the client has already refused to remove the ring. The surgery should not be canceled and the ring should not be removed without permission.

To prevent pneumonia and promote the integrity of the pulmonary system, an essential postoperative nursing intervention includes:

Ambulating the client as soon as possible The nurse should assist the client to ambulate as soon as the client is able. Incentive spirometry should be performed every 1 to 2 hours. The client should be positioned from side to side and in semi-Fowler's position. While assessing breath sounds is essential, it does not help to prevent pneumonia.

A total artificial heart (TAH) is an electrically powered pump that circulates blood into the pulmonary artery and the aorta, thus replacing the functions of both the right and left ventricles. What makes it different from an LVAD?

An LVAD only supports a failing left ventricle. A TAH is considered an extension of LVADs, which only support a failing left ventricle. TAHs are targeted for clients who are unlikely to live more than a month without further interventions.

Health teaching includes advising patients on ways to reduce PAD. The nurse should always emphasize that the strongest risk factor for the development of atherosclerotic lesions is:

Cigarette smoking. Nicotine decreases blood flow, increases heart rate and blood pressure, and increases the risk for clot formation by increasing platelet aggregation. Smokers have a four-fold higher risk of developing pain from arterial disease than nonsmokers. Carbon monoxide, produced by burning tobacco, combines with hemoglobin more readily than oxygen, thus depriving tissues of oxygen.

At which time does the nurse realize that it is best to begin teaching about care needed during the postoperative period?

During the preoperative period The best time to begin teaching about care needed in the postoperative period is during the preoperative time. At this time, the client is more alert and focused on the information provided by the nurse. Clients and family members can better be prepared and participate in the recovery period if they know what to expect. Anxiety is a factor on arrival to the surgical unit that could interfere with learning. Pain could interfere with the learning process, following a surgical procedure. At the time of discharge, both pain and timeliness may be an issue in understanding and obtaining care needed during the postoperative

The nurse is caring for a client with heart failure. What procedure should the nurse prepare the client for in order to determine the ejection fraction to measure the efficiency of the heart as a pump?

Echocardiogram The heart?'s ejection fraction is measured using an echocardiogram or multiple gated acquisition scan. A pulmonary arteriography is used to confirm corpulmonale. A chest radiograph can reveal the enlargement of the heart. An electrocardiogram is used to determine the activity of the heart?s conduction system.

A postoperative client is being discharged home after minor surgery. The PACU nurse is reviewing discharge instructions with the client and the client's spouse. What actions by the nurse are appropriate? Select all that apply.

Educate on activity limitations. Discuss wound care. Have the spouse review when to notify the physician. Provide information on health promotion topics. The nurse should provide education on activity limitations and wound care, and should review complications that require notification to the physician. The nurse should also provide information regarding health promotion topics, such as weight management and smoking cessation. The client should not make any major decisions or sign any legal forms because of the effects of anesthesia.

When the indication for surgery is without delay, the nurse recognizes that the surgery will be classified as

Emergency Emergency surgery means that the client requires immediate attention and the disorder may be life threatening. Urgent surgery means that the client requires prompt attention within 24 to 30 hours. Required surgery means that the client needs to have surgery, and it should be planned within a few weeks or months. Elective surgery means that there is an indication for surgery, but failure to have surgery will not be catastrophic.

A fractured skull would be classified under which category of surgery based on urgency?

Emergent Emergent surgery occurs when the client requires immediate attention. An elective surgery is classified as a surgery that the client should have. A required surgery means that the client needs to have surgery. An urgent surgery occurs when the client requires prompt attention.

The nurse is caring for a postoperative client with a hemovac. The hemovac is expanded and contains approximately 25 cc of serosanguineous drainage. The best nursing action would be to:

Empty and measure the drainage and compress the hemovac. A hemovac needs to be recompressed periodically, because it operates with the use of gentle, constant suction. The amount of drainage is not excessive.

A nurse asks a client who had abdominal surgery 3 days ago if he has moved his bowels since surgery. The client states, "I haven't moved my bowels, but I am passing gas." How should the nurse intervene?

Encourage the client to ambulate at least three times per day. The nurse should encourage the client to ambulate at least three times per day. Ambulating stimulates peristalsis, which helps the bowels to move. It isn't appropriate to apply heat to a surgical wound. Moreover, heat application can't be initiated without a physician order. A tap water enema is typically administered as a last resort after other methods fail. A physician's order is needed with a tap water enema as well. Notifying the physician isn't necessary at this point because the client is exhibiting bowel function by passing flatus.

A patient is having an angiography to detect the presence of an aneurysm. After the contrast is administered by the interventionist, the patient begins to complain of nausea and difficulty breathing. What medication is a priority to administer at this time?

Epinephrine Infrequently, a patient may have an immediate or delayed allergic reaction to the iodine contained in the contrast agent used in angiography. Manifestations include dyspnea, nausea and vomiting, sweating, tachycardia, and numbness of the extremities. Any such reaction must be reported to the interventionalist at once; treatment may include the administration of epinephrine, antihistamines, or corticosteroids.

A patient with acute pericarditis is exhibiting distended jugular veins, tachycardia, tachypnea, bradycardia, and muffled heart sounds. The senior nursing student recognizes these symptoms occur when

Excess pericardial fluid compresses the heart and prevents adequate diastolic filling. The cardinal signs of cardiac tamponade are falling systolic blood pressure, narrowing pulse pressure, rising venous pressure (increased JVD), and distant (muffled) heart sounds. Increased pericardial pressure, reduced venous return to the heart, and decreased carbon dioxide result in cardiac tamponade (eg, compression of the heart).

The nurse concludes that further teaching about diaphragmatic breathing is needed when the client:

Exhales forcefully with a short expiration Diaphragmatic breathing should be performed gently and fully.

Which class of medication lyses and dissolves thrombi?

Fibrinolytic Thrombolytic (fibrinolytic) therapy lyses and dissolves thrombi in 50% of clients. Anticoagulants, platelet inhibitors, and factor XA inhibitors do not lyse or dissolve thrombi.

The nursing assessment of the postoperative client reveals an incision that is well-approximated with sutures intact, minimal redness and edema, and absence of drainage. The nurse recognizes the wound is healing by:

First intention First-intention healing is characterized by a closed incision with little tissue reaction and the absence of signs and symptoms of infection.

Which type of healing occurs when granulation tissue is not visible and scar formation is minimal?

First intention When wounds heal by first intention, granulation tissue is not visible and scar formation is minimal. Many postoperative wounds are covered with a dry sterile dressing. Second-intention healing (granulation) occurs in infected wounds (abscess) or in wounds in which the edges have not been well approximated. Third-intention healing (secondary suture) is used for deep wounds that either have not been sutured early or break down and are resutured later, thus bringing together two apposing granulation surfaces. Fourth-intention is not a type of wound healing.

A nurse is caring for a client experiencing dyspnea, dependent edema, hepatomegaly, crackles, and jugular vein distention. What condition should the nurse suspect?

Heart failure A client with heart failure has decreased cardiac output caused by the heart's decreased pumping ability. A buildup of fluid occurs, causing dyspnea, dependent edema, hepatomegaly, crackles, and jugular vein distention. A client with pulmonary embolism experiences acute shortness of breath, pleuritic chest pain, hemoptysis, and fever. A client with cardiac tamponade experiences muffled heart sounds, hypotension, and elevated central venous pressure. A client with tension pneumothorax has a deviated trachea and absent breath sounds on the affected side as well as dyspnea and jugular vein distention.

Providing postoperative care to a patient who has percutaneous transluminal angioplasty (PTA), with insertion of a stent, for a femoral artery lesion, includes assessment for the most serious complication of:

Hemorrhage. All choices are serious and require medical/surgical intervention. However, hemorrhage is the most serious complication that requires immediate attention.

A client in the ED has a 5-cm thoracic aortic aneurysm that was discovered during a routine chest x-ray. When obtaining the client's history, which symptoms will it be most important for the nurse to ask about?

Hoarse voice and difficulty swallowing Symptoms are dyspnea, the result of pressure of the aneurysm sac against the trachea, a main bronchus, or the lung itself; cough, frequently paroxysmal and with a brassy quality; hoarseness, stridor, or weakness or complete loss of the voice (aphonia), resulting from pressure against the laryngeal nerve; and dysphagia (difficulty in swallowing) due to impingement of the aneurysm on the esophagus.

The nurse is preparing to administer hydralazine and isosorbide dinitrate (Dilatrate). When obtaining vital signs, the nurse notes that the blood pressure is 90/60. What is the priority action by the nurse?

Hold the medication and call the physician. A combination of hydralazine and isosorbide dinitrate may be another alternative for patients who cannot take ACE inhibitors (ICSI, 2011). Nitrates (e.g., isosorbide dinitrate) cause venous dilation, which reduces the amount of blood return to the heart and lowers preload. Hydralazine lowers systemic vascular resistance and left ventricular afterload. If these medications lead to severe hypotension, the nurse should hold the medication and call the physician.

A client who underwent total hip replacement exhibits a red, painful area on the calf of the affected leg. What test validates presence of thromboembolism?

Homans' A positive Homans' sign, or pain in the calf elicited upon flexion of the ankle with the leg straight, indicates the presence of a thrombus. Testing for Romberg's sign assesses cerebellar function. Phalen's test assesses carpal tunnel syndrome. The Rinne test compares air and bone conduction in both ears to screen for or confirm hearing loss.

A patient with uncontrolled diabetes is scheduled for a surgical procedure. What chief life-threatening hazard should the nurse monitor for?

Hypoglycemia

The nurse is caring for a patient who has started anticoagulant therapy with warfarin (Coumadin). When does the nurse understand that therapeutic benefits will begin?

In 3 to 5 days Oral anticoagulants, such as warfarin, are monitored by the PT or the INR. Because the full anticoagulant effect of warfarin is delayed for 3 to 5 days, it is usually administered concurrently with heparin until desired anticoagulation has been achieved (i.e., when the PT is 1.5 to 2 times normal or the INR is 2.0 to 3.0) (Holbrook et al., 2012).

Which sign or symptom suggests that a client's abdominal aortic aneurysm is extending?

Increased abdominal and back pain Pain in the abdomen and back signify that the aneurysm is pressing downward on the lumbar nerve root and is causing more pain. The pulse rate would increase with aneurysm extension. Chest pain radiating down the arm would indicate myocardial infarction. Blood pressure would decrease with aneurysm extension, and the respiratory rate may not be affected.

A client is diagnosed with deep vein thrombosis (DVT). Which nursing diagnosis should receive highest priority at this time?

Ineffective peripheral tissue perfusion related to venous congestion Ineffective peripheral tissue perfusion related to venous congestion takes highest priority because venous inflammation and clot formation impede blood flow in a client with DVT. Impaired gas exchange related to increased blood flow is incorrect because impaired gas exchange is related to decreased, not increased, blood flow. Excess fluid volume related to peripheral vascular disease is inappropriate because there's no evidence that this client has an excess fluid volume. Risk for injury related to edema may be warranted but is secondary to ineffective tissue perfusion.

A nurse is teaching a client newly diagnosed with arterial insufficiency. Which term should the nurse use to refer to leg pain that occurs when the client is walking?

Intermittent claudication Intermittent claudication is leg pain that is brought on by exercise and relieved by rest. Dyspnea is difficulty breathing and is subjective. Orthopnea is the inability to breathe except in the upright (sitting) position. Thromboangiitis obliterans is a peripheral vascular disease also known as Buerger disease.

A client is receiving enoxaparin and warfarin therapy for a venous thromboembolism (VTE). Which laboratory value indicates that anticoagulation is adequate and enoxaparin can be discontinued?

International normalized ratio (INR) is 2.5. Oral anticoagulants such as warfarin are monitored by PT or the INR. Because the full anticoagulant effect of warfarin is delayed for 3 to 5 days, it is usually administered concurrently with heparin until desired anticoagulation has been achieved (i.e., when the PT is 1.5 to 2 times normal or the INR is 2.0 to 3.0)

Which is a characteristic of right-sided heart failure?

Jugular vein distention Jugular vein distention is a characteristic of right-sided heart failure. Dyspnea, pulmonary crackles, and cough are manifestations of left-sided heart failure.

The nurse identifies which symptom as a characteristic of right-sided heart failure?

Jugular vein distention (JVD) JVD is a characteristic of right-sided heart failure. Dyspnea, pulmonary crackles, and cough are manifestations of left-sided heart failure.

A new client has been admitted with right-sided heart failure. The nurse knows to look for which of the following assessment findings when assessing this client?

Jugular venous distention When the right ventricle cannot effectively pump blood from the ventricle into the pulmonary artery, the blood backs up into the venous system and causes jugular venous distention and congestion in the peripheral tissues and viscera. All the other choices are symptoms of left-sided heart failure.

In a client with chronic bronchitis, which sign would lead the nurse to suspect right-sided heart failure?

Leg edema Right-sided heart failure is characterized by signs of circulatory congestion, such as leg edema, jugular vein distention, and hepatomegaly. Left-sided heart failure is characterized by circumoral cyanosis, crackles, and a productive cough

A nurse is completing an assessment on a client and discovers an enlarged, red, and tender lymph node. The nurse will describe and document the lymph node using which term?

Lymphadenitis Acute lymphadenitis is demonstrated by enlarged, red, and tender lymph nodes. Lymphangitis is acute inflammation of the lymphatic channels. Lymphedema is demonstrated by swelling of tissues in the extremities because of an increased quantity of lymph that results from an obstruction of lymphatic vessels. Elephantiasis refers to a condition in which chronic swelling of the extremity recedes only slightly with elevation.

A client is diagnosed with peripheral arterial disease. Review of the client's chart shows an ankle-brachial index (ABI) on the right of 0.45. This indicates that the right foot has which of the following?

Moderate to severe arterial insufficiency Normal people without arterial insufficiency have an ABI of about 1.0. Those with an ABI of 0.95 to 0.5 have mild to moderate arterial insufficiency. Those with an ABI of less than 0.50 have ischemic rest pain. Those with tissue loss have severe ischemia and an ABI of 0.25 or less.

A postoperative client is moving from the bed to a chair when blood drips from the dressing. The nurse assesses the incision and notes evisceration. What does the nurse do first?

Moisten sterile gauze with normal saline and place on the protruding organ.

Aortic dissection may be mistaken for which of the following disease processes?

Myocardial infarction (MI) Aortic dissection may be mistaken for an acute MI, which could confuse the clinical picture and initial treatment. Aortic dissection is not mistaken for stroke, pneumothorax, or angina.

The nurse is performing wound care for a patient with a necrotic sacral wound. The prescribed treatment is isotonic saline solution with fine mesh gauze and a dry dressing to cover. What type of debridement is the nurse performing?

Nonselective debridement Nonselective débridement can be accomplished by applying isotonic saline dressings of fine mesh gauze to the ulcer. When the dressing dries, it is removed (dry), along with the debris adhering to the gauze. Pain management is usually necessary.

A client is undergoing preoperative assessment. During admission paperwork, the client reports having enjoyed a hearty breakfast this morning to be ready for the procedure. What is the nurse's next action?

Notify the surgeon.

The nurse is working in a long-term care facility with a group of older adults with cardiac disorders. Why would it be important for the nurse to closely monitor an older adult receiving digitalis preparations for cardiac disorders?

Older adults are at increased risk for toxicity. Older adults receiving digitalis preparations are at increased risk for toxicity because of the decreased ability of the kidneys to excrete the drug due to age-related changes. The margin between a therapeutic and toxic effect of digitalis preparations is narrow. Using digitalis preparations does not increase the risk of cardiac arrests, hyperthyroidism, or asthma.

An elderly client is preparing to undergo surgery. The nurse participates in preoperative care knowing that which of the following is the underlying principle that guides preoperative assessment, surgical care, and postoperative care for older adults?

Older adults have less physiologic reserve (or ability to regain physical equilibrium) than younger clients.

The nurse has medicated a postoperative client who reported nausea. Which medication would the nurse document as having been given?

Ondansetron Odansetron is an antiemetic and one of the most commonly prescribed medications for nausea and vomiting. Warfarin is an anticoagulant. Prednisone is a corticosteroid. Propofol is an anesthetic agent.

Which describes difficulty breathing when a client is lying flat?

Orthopnea Orthopnea occurs when the client is having difficulty breathing when lying flat. Sudden attacks of dyspnea at night are known as paroxysmal nocturnal dyspnea. Tachypnea is a rapid breathing rate and bradypnea is a slow breathing rate.

A client is scheduled for a cholecystectomy. Which finding by the nurse is least likely to contribute to surgical complications?

Osteoporosis Osteoporosis is likely not going to contribute to complications related to a cholecystectomy. Pregnancy decreases maternal reserves. Diabetes increases wound-healing problems and risks for infection. Urinary tract infection decreases the immune system's effectiveness, increasing the chance for infections.

Following diagnostic testing, a patient requires a cholecystectomy (Gallbladder Removal). This surgical procedure would be categorized as which of the following?

Urgent Acute gallbladder infection would be categorized as an urgent surgery. Emergent surgeries include severe bleeding, bladder or intestinal obstruction, and a fractured skull. Required surgeries include thyroid disorders and cataracts. Elective surgeries include repair of scars, simple hernia, and vaginal repair.

A client with nausea and vomiting is to receive an antiemetic that inhibits the vomiting center in the brain. Which of the following would the nurse expect the physician to order most likely?

Prochlorperazine (Compazine) Prochlorperazine is a phenothiazine that inhibits the chemoreceptor trigger zone (CTZ) and the vomiting center in the brain. Odansetron blocks receptors for 5 HT3, affecting the neural pathways involved in nausea and vomiting. Hydroxyzine and promethazine are antihistamines which block H1 receptors resulting in a decrease in stimulation of the CTZ and vomiting.

The nurse recognizes which symptom as a classic sign of cardiogenic shock?

Restlessness and confusion Cardiogenic shock occurs when decreased cardiac output leads to inadequate tissue perfusion and initiation of the shock syndrome. Inadequate tissue perfusion is manifested as cerebral hypoxia (restlessness, confusion, agitation).

As a nurse working in an ambulatory surgery center, you are admitting a client who is going to have a biopsy of a skin lesion. What is an important part of the preoperative process?

Review preoperative instructions. On admission, the nurse reviews preoperative instructions, such as diet restrictions and skin preparations, to ensure the client has followed them. The preoperative nurse does not give postoperative instructions; teach dressing changes or give instructions to caregivers.

Which method of wound healing is one in which wound edges are not surgically approximated and integumentary continuity is restored by granulation?

Second-intention healing When wounds dehisce, they are allowed to heal by secondary intention. Primary or first-intention healing is the method of healing in which wound edges are surgically approximated and integumentary continuity is restored without granulation. Third-intention healing is a method of healing in which surgical approximation of wound edges is delayed and integumentary continuity is restored by bringing apposing granulations together.

The nurse is reviewing the pre-admission laboratory findings of the client scheduled for surgery. Which of the following values would be of greatest concern to the nurse?

Potassium 6.2 mEq/L Hyperkalemia places the client at risk for surgical complications.

You are caring for a client who is an obese diabetic. The client is 48 hours post surgery. What is this client at increased risk for?

Wound dehiscence Risk factors for wound dehiscence include: Advanced age over 65 years; Chronic disease such as diabetes, hypertension, obesity; History of radiation or chemotherapy; Malnutrition, particularly insufficient protein and vitamin C; Hypoalbuminemia. This client is not at increased risk for hypotension; contractures, or phlebitis.

When assessing a postoperative client, the nurse is correct to relate which surgical risk factor that would decrease if the surgical client maintained a blood glucose level under 150 mg/dL?

Wound healing In caring for a postoperative client, the nurse is correct to correlate hyperglycemia with an increased risk of surgical incision infections and delayed wound healing. There is no direct correlation between blood glucose levels and nutrient deficiencies, respiratory complications, and liver dysfunction.

When assessing a postoperative client, the nurse is correct to relate which surgical risk factor that would decrease if the surgical client maintained a blood glucose level under 150 mg/dL?

Wound healing In caring for a postoperative client, the nurse is correct to correlate hyperglycemia with an increased risk of surgical incision infections and delayed wound healing. There is no direct correlation between blood glucose levels and nutrient deficiencies, respiratory complications, and liver dysfunction.

Nursing assessment findings reveal a temperature of 103.2°F, tachycardia, and client complaints of increased incisional pain. The nurse recognizes the client is experiencing:

Wound infection Clinical manifestations of a wound infection include fever, tachycardia, an elevated white blood cell count, and increased incisional pain.

While auscultating the heart sounds of a client with heart failure, the nurse hears an extra heart sound immediately after the second heart sound (S2). The nurse should document this as:

a third heart sound (S3). An S3 is heard following an S2, which commonly occurs in clients experiencing heart failure and results from increased filling pressures. An S1 is a normal heart sound made by the closing of the mitral and tricuspid valves. An S4 is heard before an S1 and is caused by resistance to ventricular filling. A murmur is heard when there is turbulent blood flow across the valves.

A client with left-sided heart failure complains of increasing shortness of breath and is agitated and coughing up pink-tinged, foamy sputum. The nurse should recognize these findings as signs and symptoms of:

acute pulmonary edema. Shortness of breath, agitation, and pink-tinged, foamy sputum signal acute pulmonary edema. This condition results when decreased contractility and increased fluid volume and pressure in clients with heart failure drive fluid from the pulmonary capillary beds into the alveoli. In right-sided heart failure, the client would exhibit hepatomegaly, jugular vein distention, and peripheral edema. In pneumonia, the client would have a temperature spike and sputum that varies in color. Cardiogenic shock is indicated by signs of hypotension and tachycardia

A client had a nephrectomy 2 days ago and is now complaining of abdominal pressure and nausea. The first nursing action should be to:

auscultate bowel sounds. If abdominal distention is accompanied by nausea, the nurse must first auscultate bowel sounds. If bowel sounds are absent, the nurse should suspect gastric or small intestine dilation and these findings must be reported to the physician. Palpation should be avoided postoperatively with abdominal distention. If peristalsis is absent, changing positions and inserting a rectal tube won't relieve the client's discomfort.

A client who has developed congestive heart failure must learn to make dietary adaptations. The client should avoid:

canned peas. There is a wide variety of foods that the client can still eat; the key is to have low-salt content. Canned vegetables are usually very high in salt or sodium, unless they have labels such as low-salt or sodium free or salt free. It is important to read food labels and look for foods that contain less than 300 mg sodium/serving.

The most important reason for a nurse to encourage a client with peripheral vascular disease to initiate a walking program is that this form of exercise:

decreases venous congestion. Regular walking is the best way to decrease venous congestion because using the leg muscles as a pump helps return blood to the heart. Regular exercise also aids in stress reduction and weight reduction and increases the formation of HDLs — which are all beneficial to a client with peripheral vascular disease. However, these changes don't have as significant an effect on the client's condition as decreasing venous congestion.

A client has been having cardiac symptoms for several months and is seeing a cardiologist for diagnostics to determine the cause. How will the client's ejection fraction be measured?

echocardiogram The heart's ejection fraction is measured using an echocardiogram or multiple gated acquisition scan, not an electrocardiogram or cardiac ultrasound. Cardiac catheterization is not the diagnostic tool for this measurement.

A nurse is caring for a client who underwent a skin biopsy and has three stitches in place. This wound is healing by:

first intention. Wounds with a small amount of tissue damage that are the result of procedures that use sterile technique and that are properly closed, such as with stitches, heal by first intention. Granulation tissue is generally not visible and scar formation is minimal. Second intention healing occurs in infected wounds or wounds with edges that aren't approximated. These wounds are usually packed with moist dressings. Third intention healing occurs with deep wounds that aren't sutured together, resulting in a deep, wide scar. There is no fourth intention of wound healing.

A nurse is instructing a client about using antiembolism stockings. Antiembolism stockings help prevent deep vein thrombosis (DVT) by:

forcing blood into the deep venous system. Antiembolism stockings prevent DVT by forcing blood into the deep venous system, instead of allowing blood to pool. Ambulation prevents blood from pooling and prevents DVT, but encouraging ambulation isn't a function of the stockings. Antiembolism stockings could possibly provide warmth, but this factor isn't how they prevent DVT. Elevating the extremity decreases edema but doesn't prevent DVT.

In advance of a client's scheduled appendectomy, the nurse spends significant time explaining to the client what will happen,both before the procedure and after the procedure is complete. The primary reason the nurse puts so much effort into preoperative teaching is to:

increase the likelihood of a successful recovery.

The primary objective in the immediate postoperative period is

maintaining pulmonary ventilation. The primary objective in the immediate postoperative period is to maintain pulmonary ventilation, which prevents hypoxemia. Controlling nausea and vomiting, relieving pain, and monitoring for hypotension are important, but they are not primary objectives in the immediate postoperative period.

The PACU nurse is caring for an older adult who presents with clinical manifestations of delirium. Which short-term outcome would be most important for this client? The client:

maintains adequate oxygenation status. Acute confusion associated with delirium may be a result of hypoxia, pain, urinary retention, fecal impaction, fever, hypotension, hypoglycemia, fluid loss, and anemia. Hypoxia would be most important for the nurse to address.

The nurse assesses a client to determine if there is increased risk for complications intraoperatively or postoperatively. Which are general risk factors? Select all that apply.

nutritional status age physical condition health status General surgical risk factors are related to age; nutritional status; use of alcohol, tobacco, and other substances; and physical condition.

The client is experiencing nausea and vomiting following surgery. The nurse expects the surgeon to order:

ondansetron (Zofran) Ondansetron (Zofran) is used to treat nausea and vomiting.

A client with a recent history of atrial fibrillation has been prescribed warfarin. When confirming whether the prescribed dose is safe and appropriate for the client, the nurse should:

review the client's international normalized ratio (INR). Warfarin doses are adjusted on the basis of the client's INR. Blood levels are not taken for the drug, and the client's heart rate is not the indicator of efficacy or safety.

The nurse teaches the client with peripheral vascular disease (PVD) to refrain from smoking because nicotine causes

vasospasm Nicotine causes vasospasm and can thereby dramatically reduce circulation to the extremities. Tobacco smoke also impairs transport and cellular use of oxygen and increases blood viscosity. Clients with arterial insufficiency who smoke or chew tobacco must be fully informed of the effects of nicotine on circulation and be encouraged to stop.

A nurse suspects that a client has digoxin toxicity. The nurse should assess for:

vision changes. Vision changes, such as halos around objects, are signs of digoxin toxicity. Hearing loss can be detected through hearing assessment; however, it isn't a common sign of digoxin toxicity. Intake and output aren't affected unless there is nephrotoxicity, which is uncommon. Gait changes are also uncommon.

A client with chronic heart failure is receiving digoxin (Lanoxin), 0.25 mg by mouth daily, and furosemide (Lasix), 20 mg by mouth twice daily. The nurse instructs the client to notify the physician if nausea, vomiting, diarrhea, or abdominal cramps occur because these signs and symptoms may signal digoxin toxicity. Digoxin toxicity may also cause:

visual disturbances. Digoxin toxicity may cause visual disturbances (such as, flickering flashes of light, colored or halo vision, photophobia, blurring, diplopia, and scotomata), central nervous system abnormalities (such as headache, fatigue, lethargy, depression, irritability and, if profound, seizures, delusions, hallucinations, and memory loss), and cardiovascular abnormalities (abnormal heart rate and arrhythmias). Digoxin toxicity doesn't cause taste and smell alterations. Dry mouth and urine retention typically occur with anticholinergic agents, not inotropic agents such as digoxin. Nocturia and sleep disturbances are adverse effects of furosemide — especially if the client takes the second daily dose in the evening, which may cause diuresis at night.

A nurse is caring for a client with COPD who needs teaching on pursed-lip breathing. Place the steps in order in which the nurse will instruct the client.

"Inhale through your nose." "Slowly count to 3." "Exhale slowly through pursed lips." "Slowly count to 7."

A community health nurse teaches a group of older adults about modifiable risk factors that contribute to the development of peripheral arterial disease (PAD). The nurse knows that the teaching was effective based on which statement?

"I will need to stop smoking because the nicotine causes less blood to flow to my hands and feet." The use of tobacco products may be one of the most important risk factors in the development of atherosclerotic lesions. Nicotine in tobacco decreases blood flow to the extremities and increases heart rate and blood pressure by stimulating the sympathetic nervous system. This causes vasoconstriction, thereby decreasing arterial blood flow. It also increases the risk of clot formation by increasing the aggregation of platelets.

Which nursing statement would best decrease a client's anxiety before an emergency operative procedure?

"Let me explain to you what will happen next." Many clients feel fearful of knowing little about the operative procedure and what to expect. This fear causes anxiety and can lead to a poorer response to surgery and surgical complications. Explanations of what the client is to expect can help to decrease anxiety. False reassurance of being fine does not diminish anxiety. Deep breathing and relaxation techniques can be helpful to the client, but addressing the source of the anxiety is more beneficial. Keeping the family informed helps the family and is not client focused.

A client complains of leg pain brought on by walking several blocks — a symptom that first arose several weeks earlier. The client's history includes diabetes mellitus and a two-pack-per-day cigarette habit for the past 42 years. The physician diagnoses intermittent claudication and orders pentoxifylline (Trental), 400 mg three times daily with meals. Which instruction concerning long-term care should the nurse provide?

"Practice meticulous foot care." Intermittent claudication and other chronic peripheral vascular diseases reduce oxygenation to the feet, making them susceptible to injury and poor healing. Therefore, meticulous foot care is essential. The nurse should teach the client to bathe his feet in warm water and dry them thoroughly, cut the toenails straight across, wear well-fitting shoes, and avoid taking medications without the approval of a physician. Because nicotine is a vasoconstrictor, this client should stop smoking, not just consider cutting down. Daily walking is beneficial to clients with intermittent claudication. To evaluate the effectiveness of the therapeutic regimen, this client should see the physician regularly, not just when complications occur.

A nurse is providing education about maintaining tissue integrity to a client with peripheral arterial disease. Which of the following statements by the client indicates a need for clarification?

"Shoes made of synthetic material are best for my feet." The client should wear leather shoes with an extra-depth toebox. Synthetic shoes do not allow air to circulate.

The nurse is assisting a patient with peripheral arterial disease to ambulate in the hallway. What should the nurse include in the education of the patient during ambulation?

"Walk to the point of pain, rest until the pain subsides, then resume ambulation." The nurse instructs the patient to walk to the point of pain, rest until the pain subsides, and then resume walking so that endurance can be increased as collateral circulation develops. Pain can serve as a guide in determining the appropriate amount of exercise.

A nurse prepares to suction a client's tracheostomy tube. Place the procedure steps in correct order.

1. Position the client in Fowlers position. 2. Don sterile gloves. 3. Lubricate the sterile suction catheter. 4. Insert suction catheter into the lumen of the tube. 5. Apply intermittent suction while withdrawing the catheter.

When administering heparin anticoagulant therapy, the nurse needs to make certain that the activated partial thromboplastin time (aPTT) is within the therapeutic range of:

1.5 to 2.5 times the baseline control. A normal PTT level is 21 to 35 seconds. A reading of more than 100 seconds indicates a significant risk of hemorrhage.

To assess the dorsalis pedis artery, the nurse would use the tips of three fingers and apply light pressure to the:

Anterior surface of the foot near the ankle joint. The dorsalis pedis pulse can be palpated on the dorsal surface of the foot distal to the major prominence of the navicular bone.

You are assessing a client recently admitted to your unit for hypotension. While assessing this client, you find a pulsatile mass near the umbilicus. What would you suspect?

Aortic aneurysm A pulsating mass may be felt or even seen around the umbilicus or to the left of midline over the abdomen. Options A, C, and D would not present with a pulsating mass near the umbilicus; therefore, they are incorrect.

A home health nurse is seeing an elderly female client for the first time. During the physical assessment of the client's feet, the nurse notes several circular ulcers around the tips of the toes on both feet. The bases of the ulcers are pale, and the client reports the ulcers to be very painful. From these assessment findings, the nurse suspects that the cause of the ulcers is which of the following?

Arterial insufficiency Characteristics of arterial insuffiency ulcers include location at the tips of the toes, extreme painfulness, and circular shape with pale to black ulcer bases. Ulcers caused by venous insufficiency will be irregular in shape, minimal pain if superficial (can be painful), and usually located around the ankles or the anterier tibial area.

A client is at postoperative day 1 after abdominal surgery. The client is receiving 0.9% normal saline at 75 mL/h, has a nasogastric tube to low wall suction with 200 mL every 8 hours of light yellow fluid, and a wound drain with 50 mL of dark red drainage every 8 hours. The 24-hour urine output total is 2430 mL. What action by the nurse is most appropriate?

Assess for signs and symptoms of fluid volume deficit. The client's 24-hour intake is 1800 mL (75 x 24). The client's 24-hour output is 3180 mL [(200 × 3) + (50 × 3) + 2430]. Because the output is significantly higher than the intake, the client is at risk for fluid volume deficit. The nurse should not discontinue the nasogastric suctioning without a physician's order. The findings should be documented and reassessed, but the nurse needs to take more action to prevent complication. Edema is usually associated with fluid volume excess.

When the nurse observes that a postoperative client demonstrates a constant low level of oxygen saturation via the O<sub>2</sub> saturation monitor despite the client's breathing appearing normal, what action should the nurse take first?

Assess the client's heart rhythm and nail beds.

A client is postoperative day 3 after surgical repair of an open abdominal wound and traumatic amputation of the right lower leg following a motorcycle crash. What is the highest priority nursing intervention?

Assessing WBC count, temperature, and wound appearance The client has an increased risk for infection related to the surgical wound, which is classified as dirty. Assessing the WBC count, temperature, and wound appearance allows the nurse to intervene at the earliest sign of infection. The client will have special nutritional needs during wound healing and needs education on safe transfer procedures, but the need to monitor for infection is a higher priority. The client should receive pain medication as soon as possible after asking, but the latest literature suggests that pain medication should be given on a schedule versus "as needed."

You are presenting a workshop at the senior citizens center about how the changes of aging predisposes clients to vascular occlusive disorders. What would you name as the most common cause of peripheral arterial problems in the older adult?

Atherosclerosis Atherosclerosis is the most common cause of peripheral arterial problems in the older adult. Therefore, options A, B, and D are incorrect.

A client in the emergency department states, "I have always taken a morning walk, but lately my leg cramps and hurts after just a few minutes of walking. The pain goes away after I stop walking, though." Based on this statement, which priority assessment should the nurse complete?

Attempt to palpate the dorsalis pedis and posterior tibial pulses. Intermittent claudication is a sign of peripheral arterial insufficiency. The nurse should assess for other clinical manifestations of peripheral arterial disease in a client who describes intermittent claudication. A thorough assessment of the client's skin color and temperature and the character of the peripheral pulses are important in the diagnosis of arterial disorders.

The nurse is caring for a client with Raynaud's disease. What are important instructions for a client who is diagnosed with this disease to prevent an attack?

Avoid situations that contribute to ischemic episodes. Teaching for clients with Raynaud's disease and their family members is important. The nurse should instruct the clients to avoid situations that contribute to ischemic episodes. Reporting changes in the usual pattern of chest pain or avoiding fatty foods and exercise does not help the client to avoid an attack; it is more contributory for clients with CAD. In addition, the nurse advises clients to avoid over-the-counter decongestants.

Which of the following is a key diagnostic laboratory test for heart failure?

B-type natriuretic peptide Although the other tests are important, the B-type natriuretic peptide (BNP) is important because high levels (>100 pg/mL) indicate abnormal ventricular function or symptomatic heart failure.

A patient is seen in the emergency department (ED) with heart failure secondary to dilated cardiomyopathy. What key diagnostic test does the nurse assess to determine the severity of the patient's heart failure?

B-type natriuretic peptide (BNP) The BNP level is a key diagnostic indicator of HF; high levels are a sign of high cardiac filling pressure and can aid in both the diagnosis and management of HF (Institute for Clinical Systems Improvement [ICSI], 2011).

Which of the following assessment results is considered a major risk factor for PAD?

BP of 160/110 mm Hg Hypertension is considered a major risk factor for PAD. Blood pressure should be less than 130/90 mm Hg. The other laboratory results are within the recommended range of normal to high normal.

A client is returning from the operating room after inguinal hernia repair. The nurse notes that he has fluid volume excess from the operation and is at risk for left-sided heart failure. Which sign or symptom indicates left-sided heart failure?

Bibasilar crackles Bibasilar crackles are a sign of alveolar fluid, a sequelae of left ventricular fluid, or pressure overload and indicate left-sided heart failure. Jugular vein distention, right upper quadrant pain (hepatomegaly), and dependent edema are caused by right-sided heart failure, usually a chronic condition.

A client is recovering from surgical repair of a dissecting aortic aneurysm. Which assessment findings indicate possible bleeding or recurring dissection?

Blood pressure of 82/40 mm Hg and heart rate of 125 beats/minute Assessment findings that indicate possible bleeding or recurring dissection include hypotension with reflex tachycardia (as evidenced by a blood pressure of 82/40 mm Hg and a heart rate of 125 beats/minute), decreased urine output, and unequal or absent peripheral pulses. Hematuria, increased urine output, and bradycardia aren't signs of bleeding from aneurysm repair or recurring dissection.

A client with suspected lymphoma is scheduled for lymphangiography. The nurse should inform the client that this procedure may cause which harmless temporary change?

Bluish urine Lymphangiography may turn the urine blue temporarily; it doesn't alter stool color. For several months after the procedure, the upper part of the feet may appear blue, not red. Lymphangiography doesn't affect the soles.

Which is a key diagnostic indicator of heart failure?

Brain natriuretic peptide (BNP) BNP is the key diagnostic indicator of HF. High levels of BNP are a sign of high cardiac filling pressure and can aid in the diagnosis of heart failure. BUN, creatinine, and a CBC are included in the initial workup.

A post op client reports severe abdominal pain. The nurse cannot auscultate bowel sounds and notes the client's abdomen is rigid. What is the nurse's priority action?

Call the health care provider. The client presents with a possible paralytic ileus, a serious condition where the intestines are paralyzed and peristalsis is absent. This may occur as a result of surgery, especially abdominal surgery. If the nurse is unable to auscultate bowel sounds and the client has pain and a rigid abdomen, the nurse will suspect an ileus and immediately call the health care provider. Re-attempting auscultation may occur, but only after the health care provider has been notified. The health care provider may order the placement of an NG tube, however, the nurse cannot do this without the provider's order. Administering a stool softener will not help the client and may make the condition worse.

A client is brought to the emergency department via rescue squad with suspicion of cardiogenic pulmonary edema. What complication should the nurse monitor for? Select all that apply.

Cardiac dysrhythmias Cardiac arrest Respiratory arrest Pulmonary edema is fluid accumulation in the lungs, which interferes with gas exchange in the alveoli. It represents an acute emergency and is a frequent complication of left-sided heart failure. Cardiac dysrhythmias and cardiac or respiratory arrest are associated complications. Nausea and vomiting are not complications but are symptoms of many disorders. The client is not at increased risk for the development of pulmonary embolism with pulmonary edema.

The nurse is responsible for monitoring cardiovascular function in a postoperative patient. What method can the nurse use to measure cardiovascular function?

Central venous pressure Respiratory rate, pulse rate, blood pressure, blood oxygen concentration, urinary output, level of consciousness, central venous pressure, pulmonary artery pressure, pulmonary artery wedge pressure, and cardiac output are monitored to provide information on the patient's respiratory and cardiovascular status.

A client has been prescribed furosemide (Lasix) 80 mg twice daily. The cardiac monitor technician informs the nurse that the client has started having rare premature ventricular contractions followed by runs of bigeminy lasting 2 minutes. During the assessment, the nurse determines that the client is asymptomatic and has stable vital signs. Which of the following actions should the nurse perform next?

Check the client's potassium level. The client is asymptomatic but has had a change in heart rhythm. More information is needed before calling the physician. Because the client is taking furosemide (Lasix), a potassium-wasting diuretic, the next action would be to check the client's potassium level. The nurse would then call the physician with a more complete database. The physician will need to be notified after the nurse checks the latest potassium level. Calling the nurse-manager is not indicated at this time. Administering potassium requires a physician's order.

The nurse is evaluating the client's understanding of diet teaching aimed at promoting wound healing following surgery. The nurse would conclude teaching was ineffective if the client selects which of the following?

Cheeseburger, french fries, coleslaw, and ice cream Important nutrients for wound healing include protein; vitamins A, B-complex, C, and K; arginine, magnesium, copper, and zinc; and water. The diet should be sufficient in carbohydrates and low to moderate in fats. The cheeseburger option is high in fat and low in vitamin C.

The nurse has just admitted a 12-year-old client who is going to have an above-the-knee amputation of their left leg due to osteosarcoma. The nurse knows that adequate preoperative teaching and learning is important for what reason?

Client will have a shorter recovery period. The purpose of adequate preoperative teaching/learning is for the client to have an uncomplicated and shorter recovery period. He or she will be more likely to deep breathe and cough, move as directed, and require less pain medication. Options B, C, and D are incorrect because preoperative teaching does not ensure that a 12-year-old client understands they are losing their leg or understand that they will have cancer. Preoperative teaching also does not ensure the client's family understands the child will lose their leg. This is the responsibility of the physicians who are treating the child and their family.

The nurse recognizes that the client most at risk for mortality associated with surgery is the:

Client with chronic alcoholism The client with chronic alcoholism who experiences alcohol withdrawal symptoms is at significant risk for mortality, which can be attributed to cardiac dysrthymias, cardiomyopathy, and bleeding tendencies.

A client is hospitalized for repair of an abdominal aortic aneurysm. The nurse must be alert for signs and symptoms of aneurysm rupture and thus looks for which of the following?

Constant, intense back pain and falling blood pressure Indications of a rupturing abdominal aortic aneurysm include constant, intense back pain; falling blood pressure; and decreasing hematocrit.

A nurse is caring for a client with a postoperative wound evisceration. Which action should the nurse perform first?

Cover the protruding internal organs with sterile gauze moistened with sterile saline solution.

Which of the following are indications of a rupturing aortic aneurysm? Select all that apply.

Decreasing blood pressure Decreasing hematocrit Constant, intense back pain Indications of a rupturing abdominal aneurysm include constant, intense back pain; falling blood pressure; and decreasing hematocrit.

The nurse is changing the dressing of a client who is 4 days postoperative with an abdominal wound. The nurse has changed this dressing daily since surgery. Today, the nurse notes increased serosanguinous drainage, wound edges not approximated, and a ¼-inch (6 mm) gap at the lower end of the incision. The nurse concludes which of the following conditions exists?

Dehiscence Dehiscence is a disruption of the incision.

The nurse assessing a client who has arterial insufficiency of the legs and an ulcer on the left great toe would expect to find which characteristic?

Diminished or absent pulses Occlusive arterial disease impairs blood flow and can reduce or obliterate palpable pulsations in the extremities. A diminished or absent pulse is a characteristic of arterial insufficiency.

Which aneurysm results in bleeding into the layers of the arterial wall?

Dissecting Dissection results from a rupture in the intimal layer, resulting in bleeding between the intimal and medial layers of the arterial wall. Saccular aneurysms collect blood in the weakened outpouching. In a false aneurysm, the mass is actually a pulsating hematoma. An anastomotic aneurysm occurs as a result of infection at arterial suture or graft sites.

The nurse is monitoring a presurgical patient for electrolyte imbalance. Which classification of medication may cause electrolyte imbalance?

Diuretics During anesthesia, diuretics may cause excessive respiratory depression resulting from an associated electrolyte imbalance. The other drugs listed do not cause an electrolyte imbalance.

At which time does the nurse realize that it is best to begin teaching about care needed during the postoperative period?

During the preoperative period

On postoperative day 2, a client requires care for a surgical wound using second-intention healing. What type of dressing change should the nurse anticipate doing?

Packing the wound bed with sterile saline-soaked dressing and covering it with a dry dressing Postoperative surgical wounds that are allowed to heal using second-intention healing are usually packed with a sterile saline-soaked dressing and covered with a dry dressing. The edges of a wound healing by second intention are not approximated. The wound may be cleaned using sterile saline, but the nurse would not apply a cyanoacrylate tissue adhesive. The wound should not be left open to the air, as it could expose the wound to microorganisms and dry out the wound bed, impairing healing.

Which is a classic sign of hypovolemic shock?

Pallor The classic signs of hypovolemic shock are pallor, rapid, weak thready pulse, low blood pressure, and rapid breathing

A client has been diagnosed with peripheral arterial occlusive disease. Which of the following instructions is appropriate for the nurse to give the client for promoting circulation to the extremities?

Participate in a regular walking program. Clients diagnosed with peripheral arterial occlusive disease should be encouraged to participate in a regular walking program to help develop collateral circulation. They should be advised to rest if pain develops and to resume activity when pain subsides. Extremities should be kept in a dependent position to promote circulation; elevation of the extremities will decrease circulation. Heating pads should not be used by anyone with impaired circulation to avoid burns. Massaging the calf muscles will not decrease pain. Intermittent claudication subsides with rest.

A nurse is caring for a client following an arterial vascular bypass graft in the leg. What should the nurse plan to assess over the next 24 hours?

Peripheral pulses every 15 minutes after surgery The primary objective in the postoperative period is to maintain adequate circulation through the arterial repair. Pulses, Doppler assessment, color and temperature, capillary refill, and sensory and motor function of the affected extremity are checked and compared with those of the other extremity; these values are recorded initially every 15 minutes and then at progressively longer intervals if the client's status remains stable.

The nurse recognizes that written informed consent is required for insertion of a(n):

Peripherally-inserted central catheter. Nonsurgical invasive procedures, such as insertion of a peripherally-inserted central catheter, that carry more than a slight risk to the client require written informed consent.

The client with cardiac failure is taught to report which symptom to the physician or clinic immediately?

Persistent cough Persistent cough may indicate an onset of left-sided heart failure. Loss of appetite, weight gain, interrupted sleep, unusual shortness of breath, and increased swelling should also be reported immediately.

Which health care profession has the ultimate responsibility to provide appropriate information regarding a nonemergent surgery?

Physician

A postoperative client is receiving heparin after developing thrombophlebitis. The nurse monitors the client carefully for bleeding and other adverse effects of heparin. If the client starts to exhibit signs of excessive bleeding, the nurse should expect to administer an antidote that is specific to heparin. Which agent fits this description?

Protamine sulfate Protamine sulfate is the antidote specific to heparin. Phytonadione (vitamin K) is the antidote specific to oral anticoagulants such as warfarin. (Heparin isn't given orally.) Thrombin is a hemostatic agent used to control local bleeding. Plasma protein fraction, a blood derivative, supplies colloids to the blood and expands plasma volume; it's used to treat clients who are in shock.

A client is admitted to the hospital with systolic left-sided heart failure. The nurse knows to look for which of the following assessment findings for this client?

Pulmonary congestion When the left ventricle cannot effectively pump blood out of the ventricle into the aorta, the blood backs up into the pulmonary system and causes congestion, dyspnea, and shortness of breath. All the other choices are symptoms of right-sided heart failure. They are all symptoms of systolic failure.

What complication is the nurse aware of that is associated with deep venous thrombosis?

Pulmonary embolism Serious potential venous thromboembolism complications of surgery include deep vein thrombosis and pulmonary embolism (Rothrock, 2010).

A client with systemic lupus erythematosus (SLE) complains that his hands become pale, blue, and painful when exposed to the cold. What disease should the nurse cite as an explanation for these signs and symptoms?

Raynaud's disease Raynaud's disease results from reduced blood flow to the extremities when exposed to cold or stress. It's commonly associated with connective tissue disorders such as SLE. Signs and symptoms include pallor, coldness, numbness, throbbing pain, and cyanosis. Peripheral vascular disease results from a reduced blood supply to the tissues. It occurs in the arterial or venous system. Build-up of plaque in the vessels or changes in the vessels results in reduced blood flow, causing pain, edema, and hair loss in the affected extremity. Arterial occlusive disease is the obstruction or narrowing of the lumen of the aorta and its major branches that interrupts blood flow to the legs and feet, causing pain and coolness. Buerger's disease is an inflammatory, nonatheromatous occlusive disease that causes segmental lesions and subsequent thrombus formation in arteries, resulting in decreased blood flow to the feet and legs.

A nurse is witnessing a client sign the consent form for surgery. After signing the consent form, the client starts asking questions regarding the risks and benefits of a surgical procedure. What action by the nurse is most appropriate?

Request that the surgeon come and answer the questions.

The nurse is assessing a patient with suspected acute venous insufficiency. What clinical manifestations would indicate this condition to the nurse? (Select all that apply.)

Sharp pain that may be relieved by the elevation of the extremity Cool and cyanotic skin Full superficial veins Postthrombotic syndrome is characterized by chronic venous stasis, resulting in edema, altered pigmentation, pain, and stasis dermatitis. The patient may notice the symptoms less in the morning and more in the evening. Obstruction or poor calf muscle pumping in addition to valvular reflux must be present for the development of severe postthrombotic syndrome and stasis ulcers. Superficial veins may be dilated.

A client is undergoing thoracic surgery. What priority education should the nurse provide to assist in preventing respiratory complications?

Splint the incision site using a pillow during deep breathing and coughing exercises. Splinting the incision site will help decrease pain and support the incision. This will increase compliance with the deep breathing and coughing exercises that assist in preventing respiratory complications. Pain medication should be taken regularly, not only before deep breathing and coughing exercises. Deep breathing and coughing exercises should be done at least every 2 hours, more frequently if possible. While some clients will find the exercises relaxing, most clients find it painful to complete them.

A physician admits a client to the health care facility for treatment of an abdominal aortic aneurysm. When planning this client's care, which goal should the nurse keep in mind as she formulates interventions?

Stabilizing heart rate and blood pressure and easing anxiety For a client with an aneurysm, nursing interventions focus on preventing aneurysm rupture by stabilizing heart rate and blood pressure. Easing anxiety also is important because anxiety and increased stimulation may raise the heart rate and boost blood pressure, precipitating aneurysm rupture. The client with an abdominal aortic aneurysm is typically hypertensive, so the nurse should take measures to lower blood pressure, such as administering antihypertensive agents, as ordered, to prevent aneurysm rupture. To sustain major organ perfusion, the client should maintain a mean arterial pressure of at least 60 mm Hg. Although the nurse must assess each client's mobility individually, most clients need bed rest when initially attempting to gain stability.

A nurse is providing education about the prevention of arterial constriction to a client with peripheral arterial disease. Which of the following includes priority information the nurse would give to the client?

Stop smoking. Nicotine from tobacco products causes vasospasm and can thereby dramatically reduce circulation to the extremities. When the client elevates the feet above the heart level, the heart must work against gravity to supply blood to the feet. Antiembolytic stocking are helpful for venous return to the heart, but constriction is not helpful for lack of arterial blood flow. Crossing the legs for more than a few minutes at a time compresses arteries and decreases blood supply to the legs and feet.

The nurse is educating a client scheduled for elective surgery. The client currently takes aspirin daily. What education should the nurse provide with regard to this medication?

Stop taking the aspirin 7 days before the surgery, unless otherwise directed by your physician. Aspirin should be stopped at least 7 to 10 days before surgery. The other directions provided are incorrect.

On a routine visit to the physician, a client with chronic arterial occlusive disease reports that he's stopped smoking after 34 years. To relieve symptoms of intermittent claudication, a condition associated with chronic arterial occlusive disease, which additional measure should the nurse recommend?

Taking daily walks Taking daily walks relieves symptoms of intermittent claudication, although the exact mechanism is unclear. Anaerobic exercise may make these symptoms worse. Clients with chronic arterial occlusive disease must reduce daily fat intake to 30% or less of total calories. The client should limit dietary cholesterol because hyperlipidemia is associated with atherosclerosis, a known cause of arterial occlusive disease. However, HDLs have the lowest cholesterol concentration, so this client should eat, not abstain from, foods that raise HDL levels.

What should the nurse do to manage the persistent swelling in a client with severe lymphangitis and lymphadenitis?

Teach the client how to apply an elastic sleeve In severe cases of lymphangitis and lymphadenitis with persistent swelling, the nurse teaches the client how to apply an elastic sleeve or stocking. The nurse informs the physician if the client's temperature remains elevated. The nurse recommends elevating the area to reduce the swelling and provides warmth to promote comfort and to enhance circulation.

A physician calls the nurse for an update on his client who underwent abdominal surgery 5 hours ago. The physician asks the nurse for the total amount of drainage collected in the Hemovac since surgery. The nurse reports that according to documentation, no drainage has been recorded. When the nurse finishes on the telephone, she goes to assess the client. Which assessment finding explains the absence of drainage?

The Hemovac drain isn't compressed; instead it's fully expanded. The Hemovac must be compressed to establish suction. If the Hemovac is allowed to fully expand, suction is no longer present, causing the drain to malfunction. The client who requires major abdominal surgery typically produces abdominal drainage despite the client's position. An NG tube drains stomach contents, not incisional contents. Therefore, the NG tube drainage of 400 ml is normal in this client and is not related to the absence of Hemovac drainage. Dry drainage on the dressing indicates leakage from the incision; it isn't related to the Hemovac drainage.

A nurse and physician are preparing to visit a hospitalized client with perepheral arterial disease. As you approach the client's room, the physician asks if the client has reported any intermittent claudication. The client has reported this symptom. The nurse explains to the physician which of the following details?

The client can walk about 50 feet before getting pain in the right lower leg. Intermittent claudication is caused by the inability of the arterial system to provide adequate blood flow to the tissues when increased demands are made for oxygen and nutrients during exercise. Pain is then experienced. When the client rests and decreases demands, the pain subsides. The client can then walk the same distance and repeat the process.

A nurse is caring for a client who is three hours post op from open abdominal surgery. During routine assessment, the nurse notes the previously stable client now appears anxious, apprehensive, and has a blood pressure of 90/56. What does the nurse consider is the most likely cause of the client's change in condition?

The client is displaying early signs of shock. The early stage of shock manifests with feelings of apprehension and decreased cardiac output. Late signs of shock include worsening cardiac compromise and leads to death if not treated. Medication or anesthesia reactions may cause client symptoms similar to these; however, these causes are not as likely as early shock.

A client has a myocardial infarction in the left ventricle and develops crackles bilaterally; 3-pillow orthopnea; an S3 heart sound; and a cough with pink, frothy sputum. The nurse obtains a pulse oximetry reading of 88%. What do these signs and symptoms indicate for this client?

The development of left-sided heart failure When the left ventricle fails, the heart muscle cannot contract forcefully enough to expel blood into the systemic circulation. Blood subsequently becomes congested in the left ventricle, left atrium, and finally the pulmonary vasculature. Symptoms of left-sided failure include fatigue; paroxysmal nocturnal dyspnea; orthopnea; hypoxia; crackles; cyanosis; S3 heart sound; cough with pink, frothy sputum; and elevated pulmonary capillary wedge pressure. COPD develops over many years and does not develop after a myocardial infarction. The development of right-sided heart failure would generally occur after a right ventricle myocardial infarction or after the development of left-sided heart failure. Corpulmonale is a condition in which the heart is affected secondarily by lung damage.

Which statement best describes the therapeutic action of loop diuretics?

They block sodium reabsorption in the ascending loop and dilate renal vessels. Loop diuretics block sodium reabsorption in the ascending loop of Henle, which promotes water diuresis. They also dilate renal vessels. Although loop diuretics block potassium reabsorption, this isn't a therapeutic action. Thiazide diuretics, not loop diuretics, promote sodium secretion into the distal tubule.

Which of the following is the most common site for a dissecting aneurysm?

Thoracic area The thoracic area is the most common site for a dissecting aneurysm. About one-third of patients with thoracic aneurysms die of rupture of the aneurysm.

You are caring for a client who needs to ambulate. What considerations should be included when planning the postoperative ambulatory activities for the older adult?

Tolerance Postoperative ambulatory activities are essential but planned according to the older adult's tolerance, which usually is less than that of a younger person. The respiratory depressive effects should be considered when administering certain drugs for the older adults. The convalescent period usually is longer for older adults. Therefore, they may require positive reinforcement throughout the postoperative period as well as extensive discharge planning. The convalescent period of older adults and detailed medication history may not be necessary to consider when planning the postoperative ambulatory activities.

The nurse is educating a community group about types of surgery. A member of the group asks the nurse to describe a type of surgery that is curative. What response by the nurse is true?

Tumor excision

When vomiting occurs postoperatively, what is the most important nursing intervention?

Turn the patient's head completely to one side to prevent aspiration of vomitus into the lungs. If vomiting occurs, the patient is turned to the side to prevent aspiration and the vomitus is collected in the emesis basin.

The nurse is caring for a patient with venous insufficiency. What should the nurse assess the patient's lower extremities for?

Ulceration Venous ulceration is the most serious complication of chronic venous insufficiency and can be associated with other conditions affecting the circulation of the lower extremities. Cellulitis or dermatitis may complicate the care of chronic venous insufficiency and venous ulcerations.

What symptoms should the nurse assess for in a client with lymphedema as a result of impaired nutrition to the tissue?

Ulcers and infection in the edematous area In a client with lymphedema, the tissue nutrition is impaired as a result of the stagnation of lymphatic fluid, leading to ulcers and infection in the edematous area. Later, the skin also appears thickened, rough, and discolored. Scaring does not occur in clients with lymphedema. Cyanosis is a bluish discoloration of the skin and mucous membranes.

The patient is NPO prior to having a colonoscopy. The patient is to take a daily blood pressure pill prior to the procedure. Until when may water be given prior to the procedure?

Up to 2 hours before surgery The major purpose of withholding food and fluid before surgery is to prevent aspiration. Until recently, fluid and food were restricted preoperatively overnight and often longer. The American Society of Anesthesiologists reviewed this practice and made new recommendations for people undergoing elective surgery who are otherwise healthy. Specific recommendations depend on the age of the patient and the type of food eaten. For example, adults may be advised to fast for 8 hours after eating fatty food and 4 hours after ingesting milk products. Healthy patients are allowed clear liquids up to 2 hours before an elective procedure (Crenshaw, 2011).

When a client with a history of chronic alcoholism is admitted to the hospital for surgery, the nurse anticipates that the client may show signs of alcohol withdrawal delirium during which time period?

Up to 72 hours after alcohol withdrawal

A home health nurse is seeing an elderly male client for the first time. During the physical assessment of the skin on the lower legs, the nurse notes edema, brown pigmentation in the gater area, pedal pulses, and a few irregularly shaped ulcers around the ankles. From these findings, the nurse knows that the client has a problem with peripheral circulation. Which of the following does the nurse suspect?

Venous insufficiency Symptoms of venous insufficiency include present pedal pulses, edema, pigmentation in gater area, and a reddish blue color. Ulcers caused by venous insufficiency will be irregular in shape and usually located around the ankles or the anterior tibial area. Characteristics of arterial insufficiency ulcers include location at the tips of the toes, great pain, and circular shape with a pale to black ulcer base.

The nurse is caring for a client during the immediate postoperative period and is assessing for signs of shock. What signs and symptoms indicate that the client may be in shock?

Weak and rapid pulse rate Signs and symptoms of shock include pallor, fall in blood pressure, weak and rapid pulse rate, restlessness, and cool, moist skin. Pooling of secretions in the lungs and an obstructed airway predispose the client to hypoxia and not to shock.

A 17-year-old client is having same-day surgery. Solely during the intraoperative phase of perioperative care, the nurse:

continuously monitors the sedated client. Intraoperative care includes the entire surgical procedure. During sedation, the nurse continuously evaluates the client. Assessment of heart rate, respiratory rate, BP, oxygen saturation, and level of consciousness occurs during all phases of perioperative care. Obtaining consent would occur during the preoperative phase of perioperative care. During the postoperative phase the nurse would assess how the client is recovering from anesthesia.

The term for a diagnostic test that involves injection of a contrast media into the venous system through a dorsal vein in the foot is

contrast phlebography. Also known as venography, contrast phlebography involves injecting a radiopaque contrast agent into the venous system. If a thrombus exists, the x-ray image reveals an unfilled segment of vein in an otherwise completely filled vein. Air plethysmography quantifies venous reflux and calf muscle pump ejection. In lymphangiography, contrast media are injected into the lymph system. In a lymphoscintigraphy, a radioactive-labeled colloid is injected into the lymph system.
