NCSBN 18' Exam 2 Flashcards
(250 cards)
- The nurse is caring for a client with systemic lupus erythematosis (SLE). The major complication associated with systemic lupus erythematosis is:
❍ A. Nephritis
❍ B. Cardiomegaly
❍ C. Desquamation
❍ D. Meningitis
Answer A is correct.
The major complication of SLE is lupus nephritis, which results in end-stage renal disease. SLE affects the musculoskeletal, integumentary, renal, nervous, and cardiovascular systems, but the major complication is renal involvement; therefore, answers B and D are incorrect. Answer C is incorrect because the SLE pro-
duces a “butterfly” rash, not desquamation.
- A client with benign prostatic hypertrophy has been started on Proscar (finasteride). The nurse’s discharge teaching should include:
❍ A. Telling the client’s wife not to touch the tablets
❍ B. Explaining that the medication should be taken with
meals
❍ C. Telling the client that symptoms will improve in 1–2 weeks
❍ D. Instructing the client to take the medication at bedtime, to prevent nocturia
Answer A is correct.
Finasteride is an androgen inhibitor; therefore, women who are pregnant or who might become pregnant should be told to avoid touching the tablets. Answer B is incorrect because there are no benefits to giving the medication with food. Answer C is incorrect because the medication can take 6 months to a year to be effective. Answer D is not an accurate statement; therefore, it is incorrect.
- A 5-year-old child is hospitalized for correction of congenital hip dysplasia. During the assessment of the child, the nurse can expect to find the presence of:
❍ A. Scarf sign
❍ B. Harlequin sign
❍ C. Cullen’s sign
❍ D. Trendelenburg sign
Answer D is correct.
The nurse can expect to find the presence of Trendelenburg sign. (While bearing weight on the affected hip, the pelvis tilts downward on the unaffected
side instead of tilting upward, as expected with normal stability). Scarf sign is a characteristic of the preterm newborn; therefore, answer A is incorrect. Harlequin sign can be found in normal newborns and indicates transient changes in circulation; therefore, answer B is incorrect. Answer C is incorrect because Cullen’s sign is an indication of intra-abdominal bleeding.
- Which diet is associated with an increased risk of colorectal cancer?
❍ A. Low protein, complex carbohydrates
❍ B. High protein, simple carbohydrates
❍ C. High fat, refined carbohydrates
❍ D. Low carbohydrates, complex proteins
Answer C is correct.
A diet that is high in fat and refined carbohydrates increases the risk of colorectal cancer. High fat content results in an increase in fecal bile acids, which facilitate carcinogenic changes. Refined carbohydrates increase the transit time of food through the gastrointestinal tract and increase the exposure time of the intestinal mucosa to cancer-causing substances. Answers A, B, and D do not relate to the question; therefore, they are incorrect.
- The nurse is caring for an infant following a cleft lip repair. While comforting the infant, the nurse should avoid:
❍ A. Holding the infant
❍ B. Offering a pacifier
❍ C. Providing a mobile
❍ D. Offering sterile water
Answer B is correct.
The nurse should avoid giving the infant a pacifier or bottle because sucking is not permitted. Holding the infant cradled in the arms, providing a mobile, and offering sterile water using a Breck feeder are permitted; therefore, answers A, C, and D are incorrect.
- The physician has diagnosed a client with cirrhosis characterized by asterixis. If the nurse assesses the client with asterixis, he can expect to find:
❍ A. Irregular movement of the wrist
❍ B. Enlargement of the breasts
❍ C. Dilated veins around the umbilicus
❍ D. Redness of the palmar surfaces
Answer A is correct.
The client with asterixis or “flapping tremors” will have irregular flexion and extension of the wrists when the arms are extended and the wrist is hyperextended with the fingers separated. Asterixis is associated with hepatic encephalopathy. Answers B, C, and D do not relate to asterixis; therefore, they are incorrect.
- The physician has ordered Amoxil (amoxicillin) 500mg capsules for a client with esophageal varices. The nurse can best care for the client’s needs by:
❍ A. Giving the medication as ordered
❍ B. Providing extra water with the medication
❍ C. Giving the medication with an antacid
❍ D. Requesting an alternate form of the medication
Answer D is correct.
The client with esophageal varices might develop spontaneous bleeding from the mechanical irritation caused by taking capsules; therefore, the nurse
should request the medication in an alternative form such as a suspension. Answer A is incorrect because it does not best meet the client’s needs. Answer B is incorrect because it is not the best means of preventing bleeding. Answer C is incorrect because the medications should not be given with milk or antacids.
- A client with an inguinal hernia asks the nurse why he should have surgery when he has had a hernia for years. The nurse understands that surgery is recommended to:
❍ A. Prevent strangulation of the bowel
❍ B. Prevent malabsorptive disorders
❍ C. Decrease secretion of bile salts
❍ D. Increase intestinal motility
Answer A is correct.
Surgical repair of an inguinal hernia is recommended to prevent strangulation of the bowel, which could result in intestinal obstruction and necrosis. Answer B does not relate to an inguinal hernia; therefore, it is incorrect. Bile salts, which are important to the digestion of fats, are produced by the liver, not the intestines; therefore, answer C is incorrect. Repair of the inguinal hernia will prevent swelling and obstruction associated with strangulation, but it will not increase intestinal motility; therefore, answer D is incorrect.
- The nurse is providing dietary instructions for a client with iron-deficiency anemia. Which food is a poor source of iron?
❍ A. Tomatoes
❍ B. Legumes
❍ C. Dried fruits
❍ D. Nuts
Answer A is correct.
Tomatoes are a poor source of iron, although they are an excellent source of vitamin C, which increases iron absorption. Answers B, C, and D are good sources of iron; therefore, they are incorrect.
- A client is admitted with suspected acute pancreatitis. Which lab finding confirms the diagnosis?
❍ A. Blood glucose of 260mg/dL
❍ B. White cell count of 21,000cu/mm
❍ C. Platelet count of 250,000cu/mm
❍ D. Serum amylase level of 600 units/dL
Answer D is correct.
Serum amylase levels greater than 200 units/dL help confirm the diagnosis of acute pancreatitis. Elevations of blood glucose occur with conditions other than acute pancreatitis; therefore, answer A is incorrect. Elevations in WBC are associated with infection and are not specific to acute pancreatitis; therefore, answer B is incorrect. Answer C is within the normal range; therefore, it is incorrect.
- The nurse is teaching a client with Parkinson’s disease ways to prevent curvatures of the spine associated with the disease. To prevent spinal flexion, the nurse should tell the client to:
❍ A. Periodically lie prone without a neck pillow
❍ B. Sleep only in dorsal recumbent position
❍ C. Rest in supine position with his head elevated
❍ D. Sleep on either side, but keep his back straight
Answer A is correct.
Periodically lying in a prone position without a pillow will help prevent the flexion of the spine that occurs with Parkinson’s disease. Answers B and C flex the spine; therefore, they are incorrect. Answer D is not realistic because position changes during sleep; therefore, it is incorrect.
- The physician has ordered Dilantin (phenytoin) 100mg intravenously for a client with generalized tonic clonic seizures. The nurse should administer the medication:
❍ A. Rapidly with an IV push
❍ B. With IV dextrose
❍ C. Slowly over 2–3 minutes
❍ D. Through a small vein
Answer C is correct.
The medication should be administered slowly (no more than 50mg per minute); otherwise, cardiac arrhythmias can occur. Answer A is incorrect because the medication must be given slowly. Dextrose solutions cause the medication to crystallize in the line and the medication should be given through a large vein to prevent “purple glove” syndrome; therefore, answers B and D are incorrect.
- The nurse is planning dietary changes for a client following an episode of acute pancreatitis. Which diet is suitable for the client?
❍ A. Low calorie, low carbohydrate
❍ B. High calorie, low fat
❍ C. High protein, high fat
❍ D. Low protein, high carbohydrate
Answer B is correct.
The client recovering from acute pancreatitis needs a diet that is high in calories and low in fat. Answers A, C, and D are incorrect because they can increase the client’s discomfort.
- A client is admitted with a diagnosis of polycythemia vera. The nurse should closely monitor the client for:
❍ A. Increased blood pressure
❍ B. Decreased respirations
❍ C. Increased urinary output
❍ D. Decreased oxygen saturation
Answer A is correct.
The client with polycythemia vera has an abnormal increase in the number of circulating red blood cells that results in increased viscosity of the blood. Increases in blood pressure further tax the overworked heart. Answers B, C, and D do not directly relate to the condition; therefore, they are incorrect.
- A client with hypothyroidism frequently complains of feeling cold. The nurse should tell the client that she will be more comfortable if she:
❍ A. Uses an electric blanket at night
❍ B. Dresses in extra layers of clothing
❍ C. Applies a heating pad to her feet
❍ D. Takes a hot bath morning and evening
Answer B is correct.
Dressing in extra layers of clothing will help decrease the feeling of being cold that is experienced by the client with hypothyroidism. Decreased sensation and decreased alertness are common in the client with hypothyroidism. The use of electric blankets and heating pads can result in burns, making answers A and C
incorrect. Answer D is incorrect because the client with hypothyroidism has dry skin, and a hot bath morning and evening would make her condition worse.
- The nurse caring for a client with a closed head injury obtains an intracranial pressure (ICP) reading of 17mmHg. The nurse recognizes that:
❍ A. The ICP is elevated and the doctor should be notified.
❍ B. The ICP is normal; therefore, no further action is needed.
❍ C. The ICP is low and the client needs additional IV fluids.
❍ D. The ICP reading is not as reliable as the Glascow coma scale.
Answer A is correct.
An ICP of 17mmHg should be reported to the doctor because it is elevated. (The ICP normally ranges from 4mmHg to 10mmHg, with upper limits of 15mmHg.) Answer B is incorrect because the pressure is not normal. Answer C is incorrect because the pressure is not low. Answer D is incorrect because the ICP read-
ing provides a more reliable measurement than the Glascow coma scale.
- A client has been hospitalized with a diagnosis of laryngeal cancer. Which factor is most significant in the development of laryngeal cancer?
❍ A. A family history of laryngeal cancer
❍ B. Chronic inhalation of noxious fumes
❍ C. Frequent straining of the vocal cords
❍ D. A history of frequent alcohol and tobacco use
Answer D is correct.
A history of frequent alcohol and tobacco use is the most significant factor in the development of cancer of the larynx. Answers A, B, and C are also factors in the development of laryngeal cancer but they are not the most significant; therefore, they are incorrect.
- The nurse is completing an assessment history of a client with pernicious anemia. Which complaint differentiates pernicious anemia from other types of anemia?
❍ A. Difficulty in breathing after exertion
❍ B. Numbness and tingling in the extremities
❍ C. A faster than usual heart rate
❍ D. Feelings of lightheadedness
Answer B is correct.
Numbness and tingling in the extremities is common in the client with pernicious anemia, but not those with other types of anemia. Answers A, C, and D are incorrect because they are symptoms of all types of anemia.
- A client with rheumatoid arthritis is beginning to develop flexion contractures of the knees. The nurse should tell the client to:
❍ A. Lie prone and let her feet hang over the mattress edge
❍ B. Lie supine, with her feet rotated inward
❍ C. Lie on her right side and point her toes downward
❍ D. Lie on her left side and allow her feet to remain in a neutral position
Answer A is correct.
Lying prone and allowing the feet to hang over the end of the mattress will help prevent flexion contractures. The client should be told to do this several times a day. Answers B, C, and D do not help prevent flexion contractures; therefore, they are incorrect.
- The chart of a client with schizophrenia states that the client has echolalia. The nurse can expect the client to:
❍ A. Speak using words that rhyme
❍ B. Repeat words or phrases used by others
❍ C. Include irrelevant details in conversation
❍ D. Make up new words with new meanings
Answer B is correct.
The client with echolalia will repeat words or phrases used by others. Answer A is incorrect because it refers to clang association. Answer C is incorrect because it refers to circumstantiality. Answer D is incorrect because it refers to neologisms.
- The mother of a 1-year-old with sickle cell anemia wants to know why the condition didn’t show up in the nursery. The nurse’s response is based on the knowledge that:
❍ A. There is no test to measure abnormal hemoglobin in newborns.
❍ B. Infants do not have insensible fluid loss before a year of age.
❍ C. Infants rarely have infections that would cause them to have a sickling crises.
❍ D. The presence of fetal hemoglobin protects the infant.
Answer D is correct.
The presence of fetal hemoglobin until about 6 months of age protects affected infants from episodes of sickling. Answer A is incorrect because it is an untrue statement. Answer B is incorrect because infants do have insensible fluid loss. Answer C is incorrect because respiratory infections such as bronchiolitis and otitis media can cause fever and dehydration, which cause sickle cell crisis.
- Which early morning activity helps to reduce the symptoms associated with rheumatoid arthritis?
❍ A. Brushing the teeth
❍ B. Drinking a glass of juice
❍ C. Holding a cup of coffee
❍ D. Brushing the hair
Answer C is correct.
The warmth from holding a cup of coffee or hot chocolate helps to relieve the pain and stiffness in the hands of the client with rheumatoid arthritis. Answers A, B, and D do not relieve the symptoms of rheumatoid arthritis; therefore, they are incorrect.
- A client with B negative blood requires a blood transfusion during surgery. If no B negative blood is available, the client should be transfused with:
❍ A. A positive blood
❍ B. B positive blood
❍ C. O negative blood
❍ D. AB negative blood
Answer C is correct.
If the client’s own blood type and Rh are not available, the safest transfusion is O negative blood. Answers A, B, and D are incorrect because they can cause reactions that can prove fatal to the client.
- The nurse notes that a post-operative client’s respirations have dropped from 14 to 6 breaths per minute. The nurse administers Narcan (naloxone) per standing order. Following administration of the medication, the nurse should assess the client for:
❍ A. Pupillary changes
❍ B. Projectile vomiting
❍ C. Wheezing respirations
❍ D. Sudden, intense pain
Answer D is correct.
Narcan is a narcotic antagonist that blocks the effects of the client’s pain medication; therefore, the client will experience sudden, intense pain. Answers A, B, and C do not relate to the client’s condition and the administration of Narcan; therefore, they are incorrect.
