PREP U QUESTIONS FOR UNIT 1
A client is prescribed morphine for a possible ankle fracture. When the nurse brings in a second dose of the medication, the client states, "This medicine made me sick." The nurse replies
"What do you mean by the word sick?" Explanation: Nausea may occur with opiod use; however, before taking any other action, the nurse needs to clarify that this is what the client means by the word "sick."
What complication is the nurse aware of that is associated with deep venous thrombosis?
Pulmonary embolism Explanation: Serious potential venous thromboembolism complications of surgery include deep vein thrombosis and pulmonary embolism (Rothrock, 2010).
an obese patient is scheduled for open abdominal surgery. what is the priority education for this patient?
prevention of respiratory complications
What is the blood glucose level goal for a diabetic patient who will be having a surgical procedure?
80 to 110 mg/dL
Following a total knee replacement, the surgeon orders a continuous passive motion (CPM) device. The client asks about the purpose of this treatment. The best response by the nurse is:
CPM increases circulation and range of motion of the knee joint.
The nurse is caring for a patient who is obese prior to a surgical procedure. What surgical complications positively correlated with obesity should the nurse monitor for? (Select all that apply.)
Cardiovascular system Gastrointestinal system Pulmonary system Like age, obesity increases the risk and severity of complications associated with surgery. The estimation of about 25 additional miles of blood vessels needed for every 30 pounds of excess weight results in increased cardiac demand (Alvarex, Brodsky, Lemmens, et al., 2010). The patient tends to have shallow respirations when supine, increasing the risk of hypoventilation and postoperative pulmonary complications. The acquired physical characteristics of short thick necks, large tongues, recessed chins, and redundant pharyngeal tissue, associated with increased oxygen demand and decreased pulmonary reserves, impedes intubation (Haupt & Reed, 2010). Obesity also affects the gastrointestinal system.
Which of the following medications may increases the hypotensive action of anesthesia?
Chlorpromazine (Thorazine)
During the first 24 hours after surgery, how often will the nurse evaluate the client's temperature?
Every 4 hours Explanation: The pulse rate, blood pressure, and respiration rate are recorded at least every 15 minutes for the first hour and every 30 minutes for the next 2 hours. Thereafter, they are measured less frequently if they remain stable. The temperature is monitored every 4 hours for the first 24 hours.
A classic indicator of edema and alveolar hemorrhage associated with FES is:
Hyperventilation. Explanation: Occlusion of the small vessels in the alveoli leads to a PaO2 of less than 80 mm Hg with an early respiratory alkalosis. The patient experiences hyperventilation in an attempt to get oxygen into the lungs
A client taking chlorpromazine (Thorazine) is preparing to undergo surgery. Which of the following complications does the surgical team need to prepare to deal with before anesthetics are administered?
Hypotension
A patient comes into the clinic frequently with complaints of pain. What would the nurse recognize as chronic benign pain in a patient?
Low back pain Explanation: Acute pain differs from chronic pain primarily in its duration. For example, tissue damage as a result of surgery, trauma, or burns produces acute pain, which is expected to have a relatively short duration and resolve with normal healing. Chronic pain is subcategorized as being of cancer or noncancer origin and can be time limited (e.g., may resolve within months) or persist throughout the course of a person's life. Examples of noncancer pain include peripheral neuropathy from diabetes, back or neck pain after injury, and osteoarthritis pain from joint degeneration.
After teaching a class about agents commonly associated with the development of malignant hyperthermia, the instructor determines that additional teaching is needed when the students identify which drug as a possible cause?
Morphine Explanation: Morphine is not associated with malignant hyperthermia. Agents such as halothan, succinylcholine, and epinephrine can induce malignant hyperthermia.
A client has a plaster cast applied to the left leg. Which of the following comments by the client following the procedure should the nurse address first?
My toes are stiff." Explanation: Compartment syndrome is characterized by neurovascular compromise. Stiffness of the toes may be a preliminary finding that the client is having trouble with motor function.
Unless contraindicated, how should the nurse position an unconscious patient?
On the side with a pillow at the patient's back and the chin extended, to minimize the dangers of aspiration Explanation: The head of the bed is elevated 15 to 30 degrees unless contraindicated, and the patient is closely monitored to maintain the airway as well as to minimize the risk of aspiration. If vomiting occurs, the patient is turned to the side to prevent aspiration and the vomitus is collected in the emesis basin.
Which of the following factors may contribute to rapid and shallow respirations in a postoperative client? Select all that apply.
Pain Constricting dressings Abdominal distention Obesity
Which of the following is a classic sign of hypovolemic shock?
Pallor Explanation: The classic signs of hypovolemic shock are pallor, rapid, weak thready pulse, low blood pressure, and rapid breathing.
A client with metastatic bone cancer sustained a left hip fracture without injury. What type of fracture does the nurse understand occurs without trauma or fall?
Pathologic fracture Explanation: A pathologic fracture is a fracture that occurs through an area of diseased bone and can occur without trauma or a fall. An impacted fracture is a fracture in which a bone fragment is driven into another bone fragment. A transverse fracture is a fracture straight across the bone. A compound fracture is a fracture in which damage also involves the skin or mucous membranes.
In what phase of postanesthesia care (PACU) is the client prepared for self-care or care in the hospital or an extended care setting?
Phase II PACU Explanation: In some hospitals and ambulatory surgical centers, postanesthesia care is divided into three phases. In the phase I PACU, used during the immediate recovery phase, intensive nursing care is provided. In the phase II PACU, the patient is prepared for self-care or care in the hospital or an extended care setting. In phase III PACU, the patient is prepared for discharge. There is no phase IV PACU.
A postoperative client is experiencing a flash pulmonary edema. What finding in the client's sputum is consistent with this problem?
Pink color Explanation: Flash pulmonary edema that occurs when protein and fluid accumulate in the alveoli unrelated to elevated pulmonary artery occlusive pressure. Signs and symptoms include agitation, tachypnea, tachycardia, decreased pulse oximetry readings, frothy, pink sputum, and crackles on auscultation.
A patient is scheduled for elective surgery. To prevent complication of hypotension and cardiovascular collapse, the nurse should report the use of which of the following medication ?
Prednisone (Deltasone) is a corticosteroid and puts the patient at risk for adrenal insufficiency which can cause circulatory collapse and hypotension
Which action by the nurse would be inappropriate for the client following casting?
Protect the cast by covering with a sheet. Explanation: The nurse performs actions to facilitate drying of the cast. The cast should be exposed to air. Portable fans can be used to dry the cast. Pressure on the cast should be avoided.
A client is brought to the emergency department by a softball team member who states the client and another player ran into each other, and the client is having severe pain in the right shoulder. What symptoms of a fractured clavicle does the nurse recognize?
Right shoulder slopes downward and droops inward. Explanation: The client with a fractured clavicle has restricted motion, and the affected shoulder appears to slope downward and droop inward. The client will have pain, not typically tingling and numbness in the right shoulder. Pain is not felt in the unaffected shoulder.
Which condition is a heightened response that occurs after exposure to a noxious stimulus?
Sensitization Explanation: Sensitization is a heightened response that occurs after exposure to a noxious stimulus. Pain tolerance is the maximum intensity or duration of pain that a person is willing to endure. Pain threshold is the point at which a stimulus is perceived as painful. Dependence occurs when a client who has been taking opioids experiences a withdrawal syndrome when the opioids are discontinued.
The nurse, as a member of the patient's health care team, obtains pain assessment information to identify goals for pain management. Select the most important factor that the nurse would use for goal setting:
Severity of the pain as judged by the patient Explanation: The patient's perception of pain severity should always be the primary consideration. It forms the baseline for all management.
Which of the following terms refers to an injury to ligaments and other soft tissues of a joint?
Sprain Explanation: A sprain is caused by a wrenching or twisting motion. Dislocation refers to the separation of joint surfaces. Subluxation refers to partial separation or dislocation of joint surfaces. Strain refers to a muscle pull or tear.
Which stage of surgical anesthesia is also known as excitement?
Stage II is the excitement stage that is characterized by struggling, shouting, and laughing. Stage II is often avoided if the anesthetic is administered smoothly and quickly. Stage I is the beginning of anesthesia during which the patient breathes in the anesthetic mixture and feelings of warmth, dizziness, and detachment occur. Stage III is surgical anesthesia. Surgical anesthesia is reached by continued administration of anesthetic vapor and gas. Stage IV is medullary depression. The patient is unconscious and lies quietly on the table.
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. Explanation: 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.
Select the nutrient that is important for postoperative wound healing because it helps form collagen.
Vitamin C Explanation: Vitamin C is important for capillary formation, tissue synthesis, and wound healing through collagen formation. Vitamin A decreases the inflammatory response in wounds. Magnesium is essential for wound repair, and protein allows collagen deposition.
Which of the following medications would the nurse expect to be used to facilitate intubation of the client?
attacurium (Tracrium) Explanation: Attacurium (Tracrium) is commonly used to facilitate intubation of the surgical client.
A client reports swelling and severe pain in the right wrist. After examination and radiographs negate a fracture, what would the physician likely prescribe as treatment?
splint Explanation: The client would use a splint when a musculoskeletal condition does not require rigid immobilization, causes a large degree of swelling, or requires special skin treatment.
A client develops a hemorrhage one hour post surgery. The nurse knows this is most likely an intermediary hemorrhage from a vein because it occurred:
within the first few hours, and has darkly colored blood that bubbles out slowly. Explanation: An intermediary hemorrhage appears within the first few hours following surgery. Darkly colored blood that bubbles out quickly indicates a venous hemorrhage. A hemorrhage that occurs during surgery is classified as a primary hemorrhage. A bright red color indicates that a hemorrhage's source is an artery. Secondary hemorrhages occur when sutures slip or drainage tubes dislodge insecure vessels.
You are working in the preoperative area with a client going to surgery for a cholecystectomy. The client has histamine2-receptor antagonists ordered preoperatively. The client asks you why these medications are needed. What would be your best answer?
"These medications decrease gastric acidity and volume." Explanation: The anesthesiologist frequently orders preoperative medications. Common preoperative medications include the following: anticholinergics, which decrease respiratory tract secretions, dry mucous membranes, and interrupt vagal stimulation; anti anxiety drugs, which reduce preoperative anxiety, slow motor activity, and promote induction of anesthesia; histamine2-receptor antagonists, which decrease gastric acidity and volume; narcotics, which decrease the amount of anesthesia needed, help reduce anxiety and pain, and promote sleep; sedatives, which promote sleep, decrease anxiety, and reduce the amount of anesthesia needed; and tranquilizers, which reduce nausea, prevent emesis, and enhance preoperative sedation.
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 Explanation: 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.
When caring for a patient who is deaf, which of the following should be used to elicit information regarding the patient's level of pain?
An outside interpreter should be used. Explanation: For people who are deaf of hard of hearing, outside interpreters (ie, not family members) should be used. For people with disabilities that result in communication impairment, computer-generated speech may be useful. For people who are blind and who know how to read Braille, pain assessment instruments can be obtained in Braille. The patient is deaf, so verbally asking to rate the pain on a scale would be inappropriate.
A client reports abdominal pain as "8" on a pain intensity scale of 0-10 thirty minutes after receiving an opioid intravenously. Her past medical history includes partial-thickness burns to approximately 60% of her body several years ago. The nurse assesses
That the client's past experiences with pain may influence her perception of current pain Explanation: Clients who have had previous experiences with pain are usually more frightened about subsequent painful events, as in the client who experienced partial-thickness burns to more than 60% of her body. The clients in these situations are less able to tolerate pain. Insufficient data in the stem support that the client is dependent on drugs or that this current pain is related to the client's previous burn injuries.
Which client would the nurse recognize as having the greatest risk for complications during the intraoperative or postoperative period?
The 35-year-old client with non-insulin dependent diabetes. The client with diabetes is at risk for complications during the intraoperative or postoperative period. Hypoglycemia can develop during anesthesia or from inadequate carbohydrate intake or excess insulin administration postoperatively. Hyperglycemia can increase the risk for wound infection and delay wound healing. Smokers are encouraged to stop 4 to 8 weeks before surgery. Recent ilicit drug use can increase the risk for adverse reactions to anesthesia. Healthy older adults are not at increased risk.
In which case it is most likely that pain management may not be readily forthcoming to an adult client who is in pain?
When the client's expressions of pain are incongruent with the nurse's expectations Explanation: If a client's expressions of pain are incongruent with the nurse's expectations, pain management may not be readily forthcoming. A numeric rating scale is used when assessing adults and is not inappropriate. If analgesics are contraindicated for the client's condition, several nondrug interventions can be used. The risk for improper management of pain does not increase specifically in the case of chronic pain.
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.
A client who was injured while playing basketball reports an extremely painful elbow, which is very edematous. What type of injury has the client experienced?
sprain Explanation: Sprains are injuries to the ligaments surrounding a joint. A strain is an injury to a muscle when it is stretched or pulled beyond its capacity. A contusion is a soft tissue injury resulting from a blow or blunt trauma. Sprains are injuries to the ligaments surrounding a joint.
A client who fell at home is hospitalized for a hip fracture. The client is in Buck's traction, anticipating surgery, and reports pain as "2" on a pain intensity scale of 0 to 10. The client also exhibits moderate anxiety and moves restlessly in the bed. The best nursing intervention to address the client's anxiety is to
Assess the reason for the client's anxiety. Explanation: Following the steps of the nursing process, the nurse needs to assess the reason for the client's anxiety. The client could be anxious about impending surgery, an unattended pet, a sick family member, etc. Then, the nurse intervenes appropriately by obtaining the assistance the client may need or administering anti-anxiety medication. The question is asking about treatment for anxiety. Pain medication should not be administered for anxiety. The nurse will not assist the client to a chair, because the client is on bedrest and in Buck's traction.
A client who has sustained a fracture reports an increase in pain and decreased function of the affected extremity. The nurse would suspect which of the following?
Avascular necrosis Explanation: Avascular necrosis refers to the death of the bone from insufficient blood supply, typically manifested by complaints of increased pain and decreased function. Fever or redness, purulent drainage, and swelling of the site would suggest infection. Respiratory distress would suggest a pulmonary embolism. Changes in vital signs, level of consciousness, and signs and symptoms of fluid loss would suggest hypovolemic shock.
The nurse is assigned to care for a client who has had an open reduction and internal fixation of a fractured right femur 2 days ago. The nurse is listening to the client's lungs and, when moving the gown, observes petechial hemorrhages on the skin of the chest. What is the first action by the nurse?
Call the physician to inform them of the findings. Explanation: The findings of the nurse indicate that the client may have a fat embolus, and the physician should be informed immediately. Administration of pain medication is not indicated at this time. The rash is not indicative of an allergic reaction. There is no indication that the rash is related to hemorrhage, and there is no need to increase the IV fluids.
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 Explanation: 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.
The nurse suspects the client is developing postoperative pneumonia. Which clinical manifestation would support the nurse's conclusion? Select all that apply.
Chills Crackles Tachypnea Explanation: Pneumonia is characterized by fever, chills, tachycardia, tachypnea, and crackles. Cough may or may not be present. Wheezing is not an expected finding of pneumonia.
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.
The patient presents to the emergency room with an open fracture of the femur. Which action would the nurse implement to prevent the most serious complication of an open fracture?
Cover the wound with a sterile dressing to prevent infection.
The potential effects of prior medication therapy must be evaluated before surgery. Which of the following drug classifications may cause respiratory depression from an associated electrolyte imbalance during anesthesia?
Diuretics
The nurse is assigned a client scheduled for an outpatient colonoscopy in an ambulatory care setting. During which phase of perioperative care would the nurse document the admission vital signs in the recovery room?
During the postoperative phase The nurse realizes that documentation of vital signs in the recovery room begins the postoperative phase of perioperative care. The preoperative phase occurs until the client reaches the operating area. The intra operative phase includes the entire surgical procedure until the transfer to the recovery area. There is no transfer phase of perioperative care.
The client returns to the nursing unit following an open reduction with internal fixation of the right hip. Nursing assessment findings include temperature 100.8 degrees Farenheit, heart rate 112 beats per minute, respiratory rate 28 breaths per minute, and blood pressure 86/58. There is no urine in the Foley catheter collection bag. The nurse interprets these findings as indicating which of the following complications?
Hypovolemic shock Explanation: Indicators of hypovolemic shock include a heart rate greater than 100 beats per minute, a blood pressure less than 90/60 mm Hg, and urine output less than 30 ml per hour.
What complication in the immediate postoperative period should the nurse understand requires early intervention to prevent?
Hypoxemia and hypercapnia Explanation: The primary objective in the immediate postoperative period is to maintain ventilation and thus prevent hypoxemia (reduced oxygen in the blood) and hypercapnia (excess carbon dioxide in the blood). Both can occur if the airway is obstructed and ventilation is reduced (hypoventilation). Besides administering supplemental oxygen (as prescribed), the nurse assesses respiratory rate and depth, ease of respirations, oxygen saturation, and breath sounds.
Nursing assessment findings reveal a temperature of 96.2°F, pulse oximetry 90%, shivering, and client complains of chilling. The findings are indicative of which nursing diagnosis?
Ineffective thermoregulation Explanation: Clinical manifestations of hypothermia include a low body temperature, shivering, chilling, and hypoxia.
A client is recovering from abdominal surgery and sleeping. The client had received an opioid medication 3 hours ago. The client's son requests pain medication for the client, stating "I do not want her to wake up in pain." The first nursing action is
Instruct the son about lack of client consent. Explanation: One of the client's rights is to participate in management of his or her own care. The nurse follows the nursing process by assessing the client's perception of pain but does not awaken the client to do this. The nurse can administer the pain medication only after assessment. The nurse does not administer the pain medication but does take the opportunity to educate the son.
Which area of the spinal column is subject to the greatest mechanical stress and degenerative changes?
Lower lumbar Explanation: The lower lumbar disks, L4 to L5 and L5 to S1, are subject to the greatest mechanical stress and greatest degenerative changes.
The nurse observes bloody drainage on the surgical dressing of the client who has just arrived on the nursing unit. Which intervention should the nurse plan to do next?
Outline the drainage with a pen and record the date and time next to the drainage. Explanation: Areas of drainage on the dressing should be outlined with a pen, and the date and time should be recorded next to the drainage. Blood drainage from the incision is a normal expected finding in the immediate postoperative period; however, excessive amounts should be reported to the surgeon.
Which of the following is a nondepolarizing muscle relaxant?
Pancuronium (Pavulon) Explanation: Pavulon is a nondepolarizing muscle relaxant.
Which of the following would the nurse expect a physician to use on a short-term basis for a client with an injured body part that does not require rigid immobilization?
Splint Explanation: A splint immobilizes and supports an injured body part in a functional position and is used when the condition does not require rigid immobilization, causes a large degree of swelling, or requires special skin treatment. Casts and traction provide rigid immobilization. A brace provides support, controls movement, and prevents additional injury for more long-term use.
When the nurse observes that the postoperative patient demonstrates a constant low level of oxygen saturation, although the patient's breathing appears normal, the nurse identifies that the patient may be suffering from which type of hypoxemia?
Subacute Explanation: For subacute hypoxemia supplemental oxygen may be indicated. Hypoxic hypoxemia results from inadequate breathing. Episodic hypoxemia develops suddenly, and the patient may be at risk for myocardial ischemia, cerebral dysfunction, and cardiac arrest. Anemic hypoxemia results from blood loss during surgery.
A client's left leg is in skeletal traction with a Thomas leg splint and Pearson attachment. Which intervention should the nurse include in this client's care plan?
Teach the client how to prevent problems caused by immobility. Explanation: By teaching the client about prevention measures, the nurse can help prevent problems caused by immobility, such as hypostatic pneumonia, muscle contracture, and atrophy. The nurse applies traction straps for skin traction — not skeletal traction. For a client in skeletal traction, the nurse should assess the affected limb, rather than assess the level of consciousness. Removing skeletal traction is the physician's responsibility — not the nurse's.
The nurse is planning care for a client following abdominal surgery. Which outcome demonstrates a return of functioning to the gastrointestinal tract?
The client reports a small bowel movement. Explanation: A bowel movement demonstrates that the nursing outcome of the return to function of the gastrointestinal track has been met. All of the other options are components of meeting the outcome of functioning.
The nurse should determine that a client is coughing effectively after surgery if the nurse observes which of the following activities?
The client takes a deep abdominal breath and then "huff" or "hack" coughs three or four times. Taking a deep abdominal breath and then "huff" coughing is the most effective manner of coughing. This technique helps facilitate removal of secretions and conserves energy for the client. The client should breathe slowly but not hold her breath. Short, panting breaths and then coughing from the throat do not promote expectoration of sputum from the lungs. Coughing forcefully can cause alveoli to collapse; "huff" coughing prevents this.
What measurement should the nurse report to the physician in the immediate postoperative period?
A systolic blood pressure lower than 90 mm Hg Explanation: 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 patient who underwent abdominal surgery 3 hours ago has started to hemorrhage. The nurse would classify this type of hemorrhage has which of the following?
Intermediary Explanation: Intermediary hemorrhage occurs during the first few hours after surgery when the rise of blood pressure to its normal level dislodges insecure clots formed in untied vessels. Primary hemorrhage occurs at the time of surgery. Secondary hemorrhage may occur some time after surgery if a suture slips because a blood vessel was not securely tied, became infected, or was eroded by a drainage tube.
The client with a newly applied cast complains of severe unrelenting pain. Which of the following nursing actions should the nurse do next?
Make the client NPO and notify the physician. Explanation: The client is exhibiting symptoms of compartment syndrome. The physician needs to be contacted as treatment options include bivalving of the cast or a possible fasciotomy, a surgical procedure.
Corticosteroids have which effect on wound healing?
Mask presence of infection Explanation: Corticosteroids may mask the presence of infection by impairing the normal inflammatory response. Edema may reduce blood supply. Corticosteroids do not cause hemorrhage or protein-calorie depletion.
The nurse is caring for a client 24 hours post surgery who is having persistent hiccups. What action is most appropriate for the nurse to take?
Notify the physician. Explanation: Prolonged hiccups may cause pain or discomfort. Prolonged hiccups may also result in wound dehiscence or evisceration, inability to eat, nausea and vomiting, exhaustion, and fluid, electrolyte, and acid-base imbalances. If hiccups continue, the nurse needs to notify the physician. Deep breathing helps minimize pain and will not help in this condition. Positioning the client and ample water intake will not help stop the hiccups.
What intravenous anesthetic administered by the anesthesiologist has a powerful respiratory depressant effect sufficient to cause apnea and cardiovascular depression?
Pentothal Explanation: Thiopental sodium (Pentothal) is an intravenous anesthetic agent that in large doses may cause apnea and cardiovascular depression. The other medications listed are also intravenous anesthetic agents, but none causes apnea and cardiovascular depression.
A client is scheduled to have surgery to address a cleft palate. The nurse will be preparing this client for which type of surgery?
Reconstructive Clients have surgery for many different reasons. Reconstructive surgery is intended to repair or reconstruct physical deformities and abnormalities caused by traumatic injuries, birth defects, developmental abnormalities, or disease. Exploratory surgery is a more extensive means to diagnose a problem, and usually involves exploration of a body cavity or use of scopes inserted through small incisions. Diagnostic surgery is the removal and study of tissue to make a diagnosis. Prophylactic surgery is the removal of tissue that does not yet contain cancer cells but has a high probability of becoming cancerous in the future.
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 Explanation: 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.
What does the nurse recognize as one of the most common postoperative respiratory complications in elderly patients?
Pneumonia Explanation: 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).
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) Explanation: 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 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
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. Explanation: 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.
The hazards of surgery for the aged increase as the number and severity of coexisting health problems increase. Which of the following are structural or functional changes in the elderly that impact the surgical experience? Select all that apply.
b. Increased fatty tissue prolongs elimination of anesthesia. c. Decreased ability to compensate for hypoxia increases the risk of an embolism. e. Loss of collagen increases the risk of skin complications. f. Reduced tactile sensitivity can lead to assessment and communication problems.
