MS Exam 2 Flashcards
(373 cards)
The nurse is caring for a patient who is being discharged after an emergency splenectomy following a motor vehicle crash. Which instructions should the nurse include in the discharge teaching?
a. Check often for swollen lymph nodes.
b. Watch for excess bleeding or bruising.
c. Take iron supplements to prevent anemia.
d. Wash hands and avoid persons who are ill.
ANS: D
Splenectomy increases the risk for infection, especially with gram-positive bacteria. The risks for lymphedema, bleeding, and anemia are not increased after a person has a splenectomy.
The nurse assesses a patient who has numerous petechiae on both arms. Which question should the nurse ask the patient?
a. “Are you taking any oral contraceptives?”
b. “Have you been prescribed antiseizure drugs?”
c. “Do you take medication containing salicylates?”
d. “How long have you taken antihypertensive drugs?”
ANS: C
Salicylates interfere with platelet function and can lead to petechiae and ecchymoses. Antiseizure drugs may cause anemia but not clotting disorders or bleeding. Oral contraceptives increase a person’s clotting risk. Antihypertensives do not usually cause problems with decreased clotting.
A nurse reviews the laboratory data for an older patient. The nurse would be most concerned about which finding?
a. Hematocrit of 35%
b. Hemoglobin of 11.8 g/dL
c. Platelet count of 400,000/µL
d. White blood cell (WBC) count of 2800/µL
ANS: D
Because the total WBC count is not usually affected by aging, the low WBC count in this patient would indicate that the patient’s immune function may be compromised and the underlying cause of the problem needs to be investigated. The platelet count is normal. The slight decrease in hemoglobin and hematocrit are not unusual for an older patient.
A patient with pancytopenia has a bone marrow aspiration from the left posterior iliac crest. Which action would be important for the nurse to take after the procedure?
a. Elevate the head of the bed to 45 degrees.
b. Have the patient lie on the left side for 1 hour.
c. Apply a sterile 2-inch gauze dressing to the site.
d. Use a half-inch sterile gauze to pack the wound.
ANS: B
To decrease the risk for bleeding, the patient should lie on the left side for 30 to 60 minutes. After a bone marrow biopsy, the wound is small and will not be packed with gauze. A pressure dressing is used to cover the aspiration site. There is no indication to elevate the patient’s head.
The nurse assesses a patient with pernicious anemia. Which assessment finding would the nurse expect?
a. Yellow-tinged sclerae c. Numbness of the extremities
b. Shiny, smooth tongue d. Gum bleeding and tenderness
ANS: C
Extremity numbness is associated with cobalamin (vitamin B12) deficiency or pernicious anemia. Loss of the papillae of the tongue occurs with chronic iron deficiency. Yellow-tinged sclera is associated with hemolytic anemia and the resulting jaundice. Gum bleeding and tenderness occur with thrombocytopenia or neutropenia.
A patient’s complete blood count (CBC) shows a hemoglobin of 19 g/dL and a hematocrit of 54%. Which question should the nurse ask to determine possible causes of this finding?
a. “Have you had a recent weight loss?”
b. “Do you have any history of lung disease?”
c. “Have you noticed any dark or bloody stools?”
d. “What is your dietary intake of meats and protein?”
ANS: B
The hemoglobin and hematocrit results indicate polycythemia, which can be associated with chronic obstructive pulmonary disease. The other questions would be appropriate for patients who are anemic.
The nurse is reviewing laboratory results and notes a patient’s activated partial thromboplastin time (aPTT) level of 28 seconds. The nurse should notify the health care provider in anticipation of adjusting which medication?
a. Aspirin c. Warfarin
b. Heparin d. Erythropoietin
ANS: B
aPTT assesses intrinsic coagulation by measuring factors I, II, V, VIII, IX, X, XI, XII. aPTT is increased (prolonged) in heparin administration. aPTT is used to monitor whether heparin is at a therapeutic level (needs to be greater than the normal range of 25 to 35 sec). Prothrombin time (PT) and international normalized ratio (INR) are most commonly used to test for therapeutic levels of warfarin (Coumadin). Aspirin affects platelet function. Erythropoietin is used to stimulate red blood cell production.
The nurse notes pallor of the skin and nail beds in a newly admitted patient. The nurse should ensure that which laboratory test has been ordered?
a. Platelet count c. Hemoglobin level
b. Neutrophil count d. White blood cell count
ANS: C
Pallor of the skin or nail beds is indicative of anemia, which would be indicated by a low Hgb level. Platelet counts indicate a person’s clotting ability. A neutrophil is a type of white blood cell that helps to fight infection.
The nurse examines the lymph nodes of a patient during a physical assessment. Which assessment finding would be of most concern to the nurse?
a. A 2-cm nontender supraclavicular node
b. A 1-cm mobile and nontender axillary node
c. An inability to palpate any superficial lymph nodes
d. Firm inguinal nodes in a patient with an infected foot
ANS: A
Enlarged and nontender nodes are suggestive of malignancies such as lymphoma. Firm nodes are an expected finding in an area of infection. The superficial lymph nodes are usually not palpable in adults, but if they are palpable, they are normally 0.5 to 1 cm and nontender.
A patient who had a total hip replacement had an intraoperative hemorrhage 14 hours ago. Which laboratory test result would the nurse expect?
a. Hematocrit of 46%
b. Hemoglobin of 13.8 g/dL
c. Elevated reticulocyte count
d. Decreased white blood cell (WBC) count
ANS: C
Hemorrhage causes the release of reticulocytes (immature red blood cells) from the bone marrow into circulation. The hematocrit and hemoglobin levels are normal. The WBC count is not affected by bleeding.
The complete blood count (CBC) indicates that a patient is thrombocytopenic. Which action should the nurse include in the plan of care?
a. Avoid intramuscular injections. c. Check temperature every 4 hours.
b. Encourage increased oral fluids. d. Increase intake of iron-rich foods.
ANS: A
Thrombocytopenia is a decreased number of platelets, which places the patient at high risk for bleeding. Neutropenic patients are at high risk for infection and sepsis and should be monitored frequently for signs of infection. Encouraging fluid intake and iron-rich food intake is not indicated in a patient with thrombocytopenia.
The health care provider’s progress note for a patient states that the complete blood count (CBC) shows a “shift to the left.” Which assessment finding will the nurse expect?
a. Cool extremities c. Elevated temperature
b. Pallor and weakness d. Low oxygen saturation
ANS: C
The term “shift to the left” indicates that the number of immature polymorphonuclear neutrophils (bands) is elevated and that finding is a sign of infection. There is no indication that the patient is at risk for hypoxemia, pallor or weakness, or cool extremities.
The health care provider orders a liver and spleen scan for a patient who has been in a motor vehicle crash. Which action should the nurse take before this procedure?
a. Check for any iodine allergy. c. Administer prescribed sedatives.
b. Insert a large-bore IV catheter. d. Assist the patient to a flat position.
ANS: D
During a liver and spleen scan, a radioactive isotope is injected IV, and images from the radioactive emission are used to evaluate the structure of the spleen and liver. An indwelling IV catheter and sedation are not needed. The patient is placed in a flat position before the scan.
A patient with pancytopenia of unknown origin is scheduled for the following diagnostic tests. The nurse will provide a consent form to sign for which test?
a. Bone marrow biopsy
b. Abdominal ultrasound
c. Complete blood count (CBC)
d. Activated partial thromboplastin time (aPTT)
ANS: A
A bone marrow biopsy is a minor surgical procedure that requires the patient or guardian to sign a surgical consent form. The other procedures do not require a signed consent.
The nurse reviews the laboratory test results of a patient admitted with abdominal pain. Which information will be most important for the nurse to communicate to the health care provider?
a. Monocytes 4%
b. Hemoglobin 13.6 g/dL
c. Platelet count 168,000/µL
d. White blood cell (WBC) count 15,500/µL
ANS: D
The elevation in WBCs indicates that the patient has an inflammatory or infectious process ongoing, which may be the cause of the patient’s pain, and that further diagnostic testing is needed. The monocytes are at a normal level. The hemoglobin and platelet counts are normal.
Which information shown in the table below about a patient who has just arrived in the emergency department is most urgent for the nurse to communicate to the health care provider?
Assessment Complete Blood Count Patient History
• BP 110/68
• Pulse 98 beats/min
• Brisk capillary refill
• Multiple ecchymoses on arms • Hgb 10.6 g/dL
• Hct 30%
• WBC 5100/µL
• Platelets 19,500/µL • Occasional aspirin use
• Abdominal pain x 1 week
• Large, dark stool this morning
a. Heart rate c. Abdominal pain
b. Platelet count d. White blood cell count
ANS: B
The platelet count is severely decreased and places the patient at risk for spontaneous bleeding. The other information is also pertinent but not as indicative of the need for rapid treatment as the platelet count.
A 62-year old man with chronic anemia is experiencing increased fatigue and occasional palpitations at rest. The nurse would expect the patient’s laboratory test findings to include
a. an RBC count of 4,500,000/L.
b. a hematocrit (Hct) value of 38%.
c. normal red blood cell (RBC) indices.
d. a hemoglobin (Hgb) of 8.6 g/dL (86 g/L).
ANS: D
The patient’s clinical manifestations indicate moderate anemia, which is consistent with a Hgb of 6 to 10 g/dL. The other values are all within the range of normal.
Which menu choice indicates that the patient understands the nurse’s teaching about recommended dietary choices for iron-deficiency anemia?
a. Omelet and whole wheat toast c. Strawberry and banana fruit plate
b. Cantaloupe and cottage cheese d. Cornmeal muffin and orange juice
ANS: A
Eggs and whole grain breads are high in iron. The other choices are appropriate for other nutritional deficiencies but are not the best choice for a patient with iron-deficiency anemia.
A patient who is receiving methotrexate for severe rheumatoid arthritis develops a megaloblastic anemia. The nurse will anticipate teaching the patient about increasing oral intake of
a. iron. c. cobalamin (vitamin B12).
b. folic acid. d. ascorbic acid (vitamin C).
ANS: B
Methotrexate use can lead to folic acid deficiency. Supplementation with oral folic acid supplements is the usual treatment. The other nutrients would not correct folic acid deficiency, although they would be used to treat other types of anemia.
A 52-yr-old patient has a new diagnosis of pernicious anemia. The nurse determines that the patient understands the teaching about the disorder when the patient states,
a. “I need to start eating more red meat and liver.”
b. “I will stop having a glass of wine with dinner.”
c. “I could choose nasal spray rather than injections of vitamin B12.”
d. “I will need to take a proton pump inhibitor such as omeprazole (Prilosec).”
ANS: C
Because pernicious anemia prevents the absorption of vitamin B12, this patient requires injections or intranasal administration of cobalamin. Alcohol use does not cause cobalamin deficiency. Proton pump inhibitors decrease the absorption of vitamin B12. Eating more foods rich in vitamin B12 is not helpful because the lack of intrinsic factor prevents absorption of the vitamin.
An appropriate nursing intervention for a hospitalized patient with severe hemolytic anemia is to
a. provide a diet high in vitamin K.
b. alternate periods of rest and activity.
c. teach the patient how to avoid injury.
d. place the patient on protective isolation.
ANS: B
Nursing care for patients with anemia should alternate periods of rest and activity to encourage activity without causing undue fatigue. There is no indication that the patient has a bleeding disorder, so a diet high in vitamin K or teaching about how to avoid injury is not needed. Protective isolation might be used for a patient with aplastic anemia, but it is not indicated for hemolytic anemia.
Which patient statement to the nurse indicates a need for additional instruction about taking oral ferrous sulfate?
a. “I will call my health care provider if my stools turn black.”
b. “I will take a stool softener if I feel constipated occasionally.”
c. “I should take the iron with orange juice about an hour before eating.”
d. “I should increase my fluid and fiber intake while I am taking iron tablets.”
ANS: A
It is normal for the stools to appear black when a patient is taking iron, and the patient should not call the health care provider about this. The other patient statements are correct.
Which collaborative problem will the nurse include in a care plan for a patient admitted to the hospital with idiopathic aplastic anemia?
a. Potential complication: seizures
b. Potential complication: infection
c. Potential complication: neurogenic shock
d. Potential complication: pulmonary edema
ANS: B
Because the patient with aplastic anemia has pancytopenia, the patient is at risk for infection and bleeding. There is no increased risk for seizures, neurogenic shock, or pulmonary edema.
It is important for the nurse providing care for a patient with sickle cell crisis to
a. limit the patient’s intake of oral and IV fluids.
b. evaluate the effectiveness of opioid analgesics.
c. encourage the patient to ambulate as much as tolerated.
d. teach the patient about high-protein, high-calorie foods.
ANS: B
Pain is the most common clinical manifestation of a crisis and usually requires large doses of continuous opioids for control. Fluid intake should be increased to reduce blood viscosity and improve perfusion. Rest is usually ordered to decrease metabolic requirements. Patients are instructed about the need for dietary folic acid, but high-protein, high-calorie diets are not emphasized.
