A patient who has vague symptoms of fatigue, headaches, and a positive test for human immunodeficiency virus (HIV) antibodies using an enzyme immunoassay (EIA) test. What instructions should the nurse give to this patient? a. "The EIA test will need to be repeated to verify the results." b. "A viral culture will be done to determine the progression of the disease." c. "It will probably be 10 or more years before you develop acquired immunodeficiency syndrome (AIDS)." d. "The Western blot test will be done to determine whether acquired immunodeficiency syndrome (AIDS) has developed."

ANS: A After an initial positive EIA test, the EIA is repeated before more specific testing such as the Western blot is done. Viral cultures are not usually part of HIV testing. It is not appropriate for the nurse to predict the time frame for AIDS development. The Western blot tests for HIV antibodies, not for AIDS.

"I will wear gloves while changing the pet litter box." B. "I will rinse raw fruits with water before eating them." C. "I will wear a mask when around family members who are ill." D. "I will cook vegetables before eating them."

A. INCORRECT: A client who has AIDS should avoid changing the pet litter box to prevent acquiring toxoplasmosis. B. INCORRECT: A client who has AIDS should avoid consuming raw fruits due to the presence of bacteria that can cause opportunistic infections. C. INCORRECT: Due to compromised immune response, a client who has AIDS should avoid contact with family members who are ill. D. CORRECT: A client who has AIDS should cook vegetables before eating to kill bacteria that cause opportunistic infections.

To prevent recurrence of cystitis, the nurse should plan to encourage the female client to include which of the following measures in her daily routine? A. Wearing cotton underpants. B. Increasing citrus juice intake. C. Douching regularly with 0.25% acetic acid. D. Using vaginal sprays.

A. Wearing cotton underpants. A woman can adopt several health-promotion measures to prevent the recurrence of cystitis, including avoiding too-tight pants, noncotton underpants, and irritating substances, such as bubble baths and vaginal soaps and sprays. Increasing citrus juice intake can be a bladder irritant. Regular douching is not recommended; it can alter the pH of the vagina, increasing the risk of infection.

(NCLEX question) True or False: NSAIDs are used as first-line treatment for pain relief with patients with ulcerative colitis.* True False

FALSE. NSAIDs should be avoided in patients with ulcerative colitis because they can cause a "flare-up" in the condition. Tylenol should be used instead or a similar medication that isn't an NSAID.

A client with acquired immunodeficiency syndrome (AIDS) reports speech, gait, and vision difficulty. The nurse observes the client is confused and lethargic. Which microorganism is most likely responsible for this condition? Candida albicans Toxoplasma gondii Pneumocystis jiroveci Mycobacterium tuberculosis

Toxoplasma gondii

The nurse performs a skin test on a client who has a mosquito bite. The client shows wheal and flare reaction post-skin test. Which type of hypersensitivity reaction most likely has occurred? Type 1 Type II Type III Type IV

Type 1 Type I is an IgE-mediated hypersensitivity reaction that causes wheal and flare response. This reaction is characterized by a pale wheal containing edematous fluid surrounded by a red flare from the hyperemia. Type II is a cytotoxic hypersensitivity reaction that involves IgG and IgM antibodies but does not show any wheal and flare response. Type III hypersensitivity reaction is an immune complex-mediated reaction that involves erythema and edema in 3 to 8 hours. Type IV is a delayed hypersensitivity reaction that involves erythema and edema in 24 to 48 hours.

After reviewing the urinalysis reports of a client with a renal disorder, the nurse concludes that the client may have a urinary tract infection. Which urinary laboratory findings enabled the nurse to make this conclusion? Select all that apply. 1 )pH: 8.5 2 )Specific gravity: 1.010 3 )Red blood cells: 3/hpf 4 )Osmolality: 1500 mOsm/kg (1500 mmol/kg) 5 )White blood cells: 6/hpf

1 )pH: 8.5 5 )White blood cells: 6/hpf The client may have a urinary tract infection, as the urinalysis reports show the presence of pH as 8.5 and white blood cells as 6/hpf in the urine. A pH above 8.0 indicates a urinary tract infection; client's is 8.5. The normal level of white blood cells (WBC) in urine should be less than 5/hpf; therefore, the WBC level of 6/hpf indicates urinary tract infection. The specific gravity of 1.010 indicates a normal finding. The normal level of red blood cells (RBC) is less than 4/hpf; therefore, the RBC levels of 3/hpf indicates normal finding. Osmolality of 1500 mOsm/kg (1500 mmol/kg) indicates tubular dysfunction.

What size of induration after a tuberculin test signifies a positive result in a 16-year-old client? Record your answer using a whole number. _________________ mm

The nurse should consider an induration of 10 mm (1 cm) a positive sign of tuberculin testing in a 16-year-old client.

The nurse presents a seminar on HIV testing to a group of seniors and their caregivers in an assisted living facility. Which responses fit the Centers for Disease Control and Prevention's (CDC's) recommendations for HIV testing? (Select all that apply.) A) ''I am 78 years old and I was treated and cured of syphilis many years ago.'' B) ''In 1986, I received a transfusion of platelets.'' C) ''Seven years ago, I was released from a penitentiary.'' D) ''I used to smoke marijuana 30 years ago, but I have not done any drugs since.'' E) ''I had sex with a man with a disreputable past from New York back in the late 1960s, but I have been happily married since 1971.'' F) ''At 68, I am going to get married for the fourth time.'' G) ''Downtown was where I picked up the best hookers back in the 1950s.'

-(A, C, F) A) ''I am 78 years old and I was treated and cured of syphilis many years ago.'' Rationale: People who have had sexually transmitted diseases should be tested for HIV. C) ''Seven years ago, I was released from a penitentiary.'' Rationale: HIV testing is recommended for people who are or have been in jails or prisons. F) ''At 68, I am going to get married for the fourth time.'' Rationale: People who are planning to get married should be tested for HIV. Incorrect: B) ''In 1986, I received a transfusion of platelets.'' Rationale: People who received blood transfusions between 1978 and 1985 should be tested for HIV. D) ''I used to smoke marijuana 30 years ago, but I have not done any drugs since.'' Rationale: HIV testing is recommended only for injection drug users. E) ''I had sex with a man with a disreputable past from New York back in the late 1960s, but I have been happily married since 1971.'' Rationale: AIDS cases were extremely rare prior to the 1970s.

(NCLEX question) A 36 year old female, who is 29 weeks pregnant, reports she is experiencing burning when voiding. The physician orders a urinalysis. Which statement by the patient demonstrates she understands how to collect the specimen?* A. "I'll hold the cup firmly against the urethra while collecting the sample." B. "I will cleanse back to front with the antiseptic wipe before peeing in the cup." C. "First, I will pee a small amount of urine in the toilet and then collect the rest in the cup." D. "I will be sure to drink a lot of fluids to keep the urine diluted before peeing into the cup."

C. "First, I will pee a small amount of urine in the toilet and then collect the rest in the cup." When collecting a urinalysis it is important to avoid contaminating the sample. So, the patient will collect the urine during mid-stream. The patient will void a small amount in the toilet and then void the rest into the cup (until it is halfway full). The cup should be placed a few inches away from the urethra and prior to voiding the patient should use an antiseptic wipe to cleanse the labia from front to back. It is best to collect the sample when the bladder has been full for 2-3 hours, therefore the urine in concentrated not diluted.

(NCLEX question) A patient is receiving treatment for ulcerative colitis by taking Azathioprine. Which physician's order would the nurse question if received?* A. Ambulate the patient twice day B. Low-fiber and high-protein diet C. Administer varicella vaccine intramuscularly D. Administer calcium carbonate by mouth daily

C. Administer varicella vaccine intramuscularly Azathioprine is an immunosuppression medication that decreases the immune system. Therefore, the patient should never receive a live vaccine, such as Varicella. Other vaccinations that are live include: MMR, Shingles, Nasal influenza mist etc.

(power points) Primary prevention for OM A. Prevnar vaccination B. Influenza vaccination C. Breast feeding D. Screening for effusion E. Avoid propping bottle F.

Primary prevention for OM A. Prevnar vaccination B. Influenza vaccination C. Breast feeding E. Avoid propping bottle F. Decrease or discontinue pacifier use after 6 months G. Avoid exposure to tobacco smoke Secondary prevention D. Screening for effusion-->done in infants and preschoolers H. Hearing screening for children with learning disability--> related to MME

The nurse is educating a client about protease inhibitors. What statement about protease inhibitors is true? A. Protease inhibitors prevent viral replication. B. Protease inhibitors prevent the interaction between viral material and the CD4+ T-cell. C. Protease inhibitors prevent viral and host genetic material integration. D. Protease inhibitors prevent the clipping of the viral strands into small functional pieces.

Protease inhibitors act by preventing the newly formed viral strands within the host CD4+ T-cell from being clipped into smaller functional pieces. Nucleoside reverse transcriptase inhibitors (NRTIs) prevent viral replication. NRTIs inhibits the transformation of viral single-stranded ribonucleic acid into host double-stranded deoxyribonucleic acid (DNA) by the action of the enzyme reverse transcriptase. Entry inhibitor drugs prevent the binding of the virus to the CD4 receptors. Integrase inhibitor drugs prevent the integration of viral material into the host's DNA by the action of the enzyme integrase.

Suprapubic discomfort or pressure J. hematuria K. cloudy appearance to urine L. urinary retention

Related to bladder emptying: F. post-void dribbling H. Hesitancy L. urinary retention D. dysuria Related to bladder storage: A. Urinary frequency > 8 times in 24 hr period (often <200 ml each voiding) B. Urgency C. Incontinence E. intermittency G. nocturia/nocturnal enuresis I. Suprapubic discomfort or pressure J. hematuria K. cloudy appearance to urine

(Self assessment question) Which important proinflammatory mediator is responsible for initiating neutrophil and macrophage chemotaxis to the site of tissue injury during inflammation? A. Leukotrienes B. Bradykinins C. Transforming growth factor D. Complement proteins

D. Complement proteins Complement proteins are very important, especially C3a, C4a, and C5a, because they initiate chemotaxis (movement) of neutrophils and macrophages toward the site of tissue injury during inflammation

(Custom adaptive ) Which laboratory test will be elevated in a client with inflammatory arthritis? A. Leukocyte count B. Hemoglobin and hematocrit C. Blood urea nitrogen and creatinine D. Erythrocyte sedimentation rate (ESR)

D. Erythrocyte sedimentation rate (ESR) The erythrocyte sedimentation rate (ESR) measures the rate at which red blood cells fall through plasma. This rate is most significantly affected by an increased number of acute-phase reactants, which occur with inflammation. An elevated ESR (>20 mm/hr) indicates inflammation or infection somewhere in the body. The ESR is chronically elevated with inflammatory arthritis. Leukocytes will be elevated when a bacterial infection is present. Hemoglobin and hematocrit are not used to determine the presence of inflammation. Blood urea nitrogen and creatinine levels are used to determine renal function.

(NCLEX question) A patient is admitted with ulcerative colitis. In the physician's notes, it is stated that the patient's barium enema results showed the patient has colitis that starts in the rectum and extends into the sigmoid and descending colon. As the nurse, you know that this is what type of ulcerative colitis? A. Right-sided colitis B. Proctosigmoiditis C. Ulcerative procotitis D. Left-sided colitis

D. Left-sided colitis Left-sided colitis (distal colitis) starts in the rectum and goes to the sigmoid and descending colon. Ulcerative proctitis affects the rectum only. Proctosigmoiditis affects the rectum and sigmoid colon. Right-sided colitis is NOT a type of ulcerative colitis

(NCLEX question) A patient, who is having spasms and burning while urinating due to a UTI, is prescribed "Pyridium" (Phenazopyridine). Which option below is a normal side effect of this drug?* A. Hematuria B. Crystalluria C. Urethra mucous D. Orange colored urine

D. Orange colored urine Orange colored urine is a normal side effect of Pyridium which acts as a pain reliever to decreasing frequent urination and pain associated with a UTI.

*A school-aged child who has just arrived from Africa has been exposed to diphtheria, and a nurse in the pediatric clinic is to administer the antitoxin. Which type of immunity does the antitoxin confer? A. Active natural B. Passive natural C. Active artificial D. Passive artificial

D. Passive artificial In the creation of passive artificial immunity an antibody is produced in another organism and then injected into the infected or presumed infected person to provide immediate immunity against the invading organism. Active natural immunity takes too much time to develop; this child needs immediate protection. Passive natural immunity is acquired from the mother and is effective only during the first few months of life. Active artificial immunity takes too much time to develop; the child needs immediate protection.

What does the nurse explain to a client that a positive diagnosis for human immunodeficiency virus (HIV) infection is based on? A. Performance of high-risk sexual behaviors B. Evidence of extreme weight loss and high fever C. Identification of an associated opportunistic infection D. Positive enzyme-linked immunosorbent assay (ELISA) and Western blot tests

D. Positive enzyme-linked immunosorbent assay (ELISA) and Western blot tests Positive ELISA and Western blot tests confirm the presence of HIV antibodies that occur in response to the presence of the HIV. Performance of high-risk sexual behaviors places someone at risk but does not constitute a positive diagnosis. Evidence of extreme weight loss and high fever do not confirm the presence of HIV; these adaptations are related to many disorders, not just HIV infection. The diagnosis of just an opportunistic infection is not sufficient to confirm the diagnosis of HIV. An opportunistic infection (included in the Centers for Disease Control and Prevention surveillance case definition for acquired immunodeficiency syndrome [AIDS]) in the presence of HIV antibodies indicates that the individual has AIDS.

(NCLEX question) A 76 year old female is admitted due to a recent fall. The patient is confused and agitated. The family members report that this is not normal behavior for the patient. They explain that the patient is very active in the community and cares for herself. Based on the information you have gathered about the patient, which physician's order takes priority?* A. "Collect a urinalysis" B. "Collect a T3 and T4 level" C. "Insert a Foley Catheter" D. "Keep patient NPO"

A. "Collect a urinalysis" Elderly patients do NOT exhibit the typical signs and symptoms of a UTI. Instead, they may become confused, experience falls, become agitated etc. This can occurs in elderly patients who are normally alert and oriented and active. If this is seen in your patient, think UTI. Collecting a urinalysis (per MD order) is very important to help determine the sudden cause of confused/agitation and falling. If the U/A comes back positive for WBCs and bacteria the patient can start receiving the proper treatment.

(NCLEX question) A 63 year old patient has severe osteoarthritis in the right knee. The patient is scheduled for a knee osteotomy. You are providing pre-op teaching about this procedure to the patient. Which statement made by the patient is correct about this procedure? A. "This procedure will realign the knee and help decrease the amount of weight experienced on my right knee." B. "A knee osteotomy is also called a total knee replacement." C. "A knee osteotomy is commonly performed for patients who have osteoarthritis in both knees." D. "This procedure will realign the unaffected knee and help alleviate the amount of weight experienced on the right knee."

A. "This procedure will realign the knee and help decrease the amount of weight experienced on my right knee." The answer is A. A knee osteotomy is NOT known as a total knee replacement. A knee osteotomy can be used as an alternative for a total knee replacement but is not the same thing. In addition, a knee osteotomy is performed when there is OA on only one side of the knee.

(NCLEX question) A patient is newly diagnosed with mild ulcerative colitis. What type of anti-inflammatory medication is typically prescribed as first-line treatment for this condition?* A. 5-Aminosalicylates (Sulfasalazine) B. Immunomodulators (Adalimumab) C. Corticosteroids (Prednisone) D. Immunosupressors (Azathioprine)

A. 5-Aminosalicylates (Sulfasalazine) 5-Aminosalicylates (Sulfasalazine) are usually prescribed for mild to moderate cases of ulcerative colitis as first-line treatment. If Aminosalicylates are not working (or the patient is allergic to sulfa) corticosteriods are prescribed. Corticosteriods may be used in combination with immunosupressors. Immunosupressors and immunomodulators are used in severe cases of ulcerative colitis when other medications have not worked.

(NCLEX question) Which patients below are at risk for developing osteoarthritis? Select-all-that-apply: A. A 65 year old male with a BMI of 35. B. A 59 year old female with a history of taking long term doses of corticosteroids. C. A 55 year old male with a history of repeated right knee injuries. D. A 60 year old female with high uric acid levels.

A. A 65 year old male with a BMI of 35. C. A 55 year old male with a history of repeated right knee injuries. The answers are A and C. The risk factors for developing OA include: older age, being overweight (BMI >25), repeated injuries to the weight bearing joints, genetics. Option B is at risk for osteoporosis, and option D is at risk for gout.

(in class discussion) *5 y.o with otitis media comes into the clinic with his grandmother. The grandmother states she is confused on how to administer the oral abx at home. what could the nurse do?

A. Decrease the viral load C. Maintain or increase CD4+ T cell counts D. Prevent HIV-related symptoms and opportunistic diseases E. delay disease progression F. prevent HIV transmission.

What functions of leukocytes are involved in inflammation? Select all that apply. A. Destruction of bacteria and cellular debris B. Selective attack and destruction of non-self cells C. Release of vasoactive amines during allergic reactions D. Secretion of immunoglobulins in response to a specific antigen E. Enhancement of immune activity through secretion of various factors, cytokines, and lymphokines

A. Destruction of bacteria and cellular debris C. Release of vasoactive amines during allergic reactions Leukocytes such as monocytes and eosinophils are involved in inflammation. Their functions include the destruction of bacteria and cellular debris and the release of vasoactive amines during allergic reactions to limit these reactions. Helper/inducer T-cells and cytotoxic cells selectively attack and destroy non-self cells and secrete immunoglobulins in response to the presence of a specific antigen. B-lymphocytes, or plasma cells, secrete immunoglobulins in response to the presence of a specific antigen. Helper/inducer T-cells are involved in cell-mediated immunity, enhancing immune activity through the secretion of various factors, cytokines, and lymphokines.

On your nursing care plan for a patient with a urinary tract infection, which of the following would be appropriate nursing interventions? SELECT-ALL-THAT-APPLY:* A. Encourage voiding every 2-3 hours while awake. B. Restrict fluid intake to 1-2 liters per day. C. Monitor intake and output daily. D. The patient verbalizes the importance of using vaginal sprays to decrease reoccurrence of urinary tract infections prior to discharge home.

A. Encourage voiding every 2-3 hours while awake. C. Monitor intake and output daily. The answers are A and C. Option D is wrong become this is not a nursing intervention but a patient goal. In addition, it is an incorrect patient goal for preventing UTIs. Vaginal sprays should be avoided. Option B is wrong because fluid intake should be encouraged of 2-3 liters per day. This will help the urinary system flush out the presenting infection.

Powerpoints Nursing interventions for UTI ( select all that apply) A. Ensure adequate fluid intake - 8 (8 oz) glasses of water/day B. Recommend low fiber high-protein diet C. Tell the patient to avoid EtOH and caffeine D. Application of local heat to suprapubic area or lower back E. Offer warm shower or tub

A. Ensure adequate fluid intake - 8 (8 oz) glasses of water/day C. Tell the patient to avoid EtOH and caffeine D. Application of local heat to suprapubic area or lower back E. Offer warm shower or tub also can squirt warm water to the vaginal area during urination

(Custom adaptive ) A nurse is caring for a client with pruritic lesions from an IgE-mediated hypersensitivity reaction. Which mediator of injury is involved? A. Histamine B. Cytokine C. Neutrophil D. Macrophage

A. Histamine Histamine is one of the mediators of injury involving IgE-mediated injury that may cause pruritus. Cytokines are the mediators of injury in delayed hypersensitivity reaction. Neutrophils are involved in immune complex-mediated hypersensitivity reactions. Macrophages in tissues are involved in cytotoxic reactions.

(NCLEX question) You're providing diet teaching to a patient with ulcerative colitis about what types of foods to avoid during a "flare-up". Which foods below should the patient avoid? SELECT-ALL-THAT-APPLY:* A. Ice cream B. White Rice C. Fresh apples and pears D. Popcorn E. Cooked carrots

A. Ice cream C. Fresh apples and pears D. Popcorn Patients experiencing a flare-up with ulcerative colitis should avoid dairy products (ice cream), food that are high in fiber (fresh apples or pears) (cooked fruits without the skin would be okay), and foods that are hard to digest (popcorn). Instead, patients should consume foods low in fiber (low residue) like cooked vegetables (carrots), bland foods (white rice) etc.

(NCLEX question) You're caring for a patient with an indwelling catheter. The patient complains of spasm like pain at the catheter insertion site. Which of the following options below are other signs and symptoms the patient could experience or the nurse could observe if a urinary tract infection was present? SELECT-ALL-THAT-APPLY:* A. Increased WBC B. Crystalluria C. Positive McBurney's Sign D. Feeling the need to void even though a catheter is present E. Dark and cloudy urine F. Cramping

A. Increased WBC D. Feeling the need to void even though a catheter is present E. Dark and cloudy urine F. Cramping The answers are A, D, E and F. These are common signs and symptoms of a urinary tract infection. Options B and C are not.

Which age-related effects on the immune system are seen in the older client? A. Increased autoantibodies B. Increased expression of IL-2 receptors C. Increased delayed hypersensitivity reaction D. Increased primary and secondary antibody responses

A. Increased autoantibodies The effects of aging on the immune system include increased autoantibodies. Expression of IL-2 receptors, delayed hypersensitivity reaction, and primary and secondary antibody responses decrease in older adults because of the effects of aging on the immune system.

(Self assessment question) Histamine produces which important effects during acute inflammation? (Select all that apply.) A. Increases vasodilation B. Enhances vascular permeability C. Promotes T lymphocyte proliferation D. Activates neutrophils E. Mediates early inflammation

A. Increases vasodilation B. Enhances vascular permeability E. Mediates early inflammation Histamine is an important proinflammatory mediator released by mast cells. Similar to serotonin, histamine increases vasodilation, enhances (increases) vascular permeability, and mediates the early acute inflammatory response. Option C is incorrect because interleukin-1 promotes lymphocyte proliferation. Option D is incorrect because platelet-activating factor activates neutrophils.

A nurse is caring for a client who is human immunodeficiency virus (HIV) positive. Which complication associated with this diagnosis is most important for the nurse to teach prevention strategies? A. Infection B. Depression C. Social isolation D. Kaposi sarcoma

A. Infection The client has a weakened immune response. Instructions regarding rest, nutrition, and avoidance of unnecessary exposure to people with infections help reduce the risk for infection. Clients can be taught cognitive strategies to cope with depression, but the strategies will not prevent depression. The client may experience social isolation as a result of society's fears and misconceptions; these are beyond the client's control. Although Kaposi sarcoma is related to HIV infection, there are no specific measures to prevent its occurrence.

Which leukocyte values should be assessed to determine the adequacy of a client's response to inflammation? Select all that apply. A. Monocytes B. Neutrophils C. Plasma cells D. T-helper cells E. Macrophages

A. Monocytes B. Neutrophils E. Macrophages In response to inflammation, monocytes destroy bacteria and cellular debris; neutrophils ingest and phagocytize microorganisms and foreign protein; and macrophages destroy bacteria and cellular debris. Plasma cells are a part of antibody-mediated immunity and secrete immunoglobulins in response to the presence of a specific antigen. T-helper cells are a part of cell-mediated immunity and enhance immune activity through the secretion of various factors, cytokines, and lymphokines.

(NCLEX question) A patient with osteoarthritis is describing their signs and symptoms. Which signs and symptoms below are NOT associated with osteoarthritis? Select-all-that-apply: A. Morning stiffness greater than 30 minutes B. Experiencing grating during joint movement C. Fever and Anemia D. Symmetrical joint involvement E. Pain and stiffness tends to be worst at the end of the day

A. Morning stiffness greater than 30 minutes C. Fever and Anemia D. Symmetrical joint involvement The answers are: A, C, D. These options are signs and symptoms found with rheumatoid arthritis NOT osteoarthritis. In OA: morning stiffness is LESS than 30 minutes, it is NOT systemic as RA (so fever and anemia will not be present), and it is asymmetrical (both joints are not involved). Pain and stiffness will actually be worst at the end of the day compared to the beginning due to overuse of the joints.

(power points) Optimal immune response involves which primary functions ( select all that apply) A. Protects the body from microorganism and other antigens B. Removes dead or damaged tissue and cells C. result in regeneration of tissue that functions identically to the damaged and replaced tissue. D. Recognizes and removes cells that show abnormal cell growth/development

A. Protects the body from microorganism and other antigens B. Removes dead or damaged tissue and cells D. Recognizes and removes cells that show abnormal cell growth/development C is the optimal inflammation response

(NCLEX question) A patient with ulcerative colitis is scheduled for ileoanal anastomosis (J-Pouch) surgery. You know that this procedure:* A. Removes the colon and rectum which allows a pouch to be created that will attach to the ileum. This will allow stool to pass from the small intestine to the anus. B. Removes the colon and rectum and creates a permanent ileostomy. C. Removes the colon and creates a temporary colostomy. D. Removes the rectum which allows a pouch to be created from the colon. This will allow stool to pass from the colon to the anus.

A. Removes the colon and rectum which allows a pouch to be created that will attach to the ileum. This will allow stool to pass from the small intestine to the anus. A J-pouch surgery (ileoanal anastomosis) removes the colon and rectum which allows a pouch to be created that will attach to the ileum. This will allow stool to pass from the small intestine to the anus.

Typical signs and symptoms of UTI in an older adult ( select all that apply) A. abdominal discomfort B. cognitive impairment C. flank pain D.generalized clinical deterioration

A. abdominal discomfort B. cognitive impairment D.generalized clinical deterioration *Older adults do not not present with typicaly s/sx of UTI, rather non-localized abdominal discomfort , cognitive impairment or generalized clinical deterioration, and no fever.

(NCLEX question) During a head-to-toe assessment on a patient with a possible urinary tract infection, you perform costovertebral angle percussion. The costovertebral angle is found?* A. between the bottom of the 12th rib and spine B. between the right upper quadrant and umbilicus C. between the sternal notch and angle of Louis D. between the ischial spine and umbilicus

A. between the bottom of the 12th rib and spine The costovertebral angle is located at the angle under the 12th rib and the spine. This is where the kidneys reside. If percussion is performed at this angle and tenderness is reported it may demonstrate the kidney is inflamed due to infection. Therefore, the patient may have a kidney infection.

(Self assessment question and passport) *A patient admitted to an acute care floor has rubor of an area of injury on the left lower extremity. The nurse understands that this redness is caused by A. vasodilation. B. extravasation. C. neutrophils. D. exudate.

A. vasodilation. The inflammatory process results in rubor, or redness, of an area of insult. The body responds to injury by increasing the blood flow to an area through vasodilation. This allows increased oxygen and more nutrients and appropriate white blood cells to reach the area, isolating the area and beginning the immune response. Extravasation is the movement of fluid from its confined space into the surrounding tissue. Neutrophils are one of the most common types of white blood cells. Exudate is the fluid filled with proteins and white blood cells that moves out of the vascular spaces through extravasation

The nurse is caring for a client with otitis media and notes purulent drainage in the ear canal during the physical assessment. Which is the nurse's priority intervention? a. Obtain a specimen of the drainage for culture. b. Irrigate the ear canal with sterile normal saline. c. Gently examine the client's ear with an otoscope. d. Place a cotton ball in the ear canal to absorb the drainage.

ANS: C The nurse should use an otoscope to determine whether the client's tympanic membrane has ruptured. Until the tympanic membrane is examined and is found to be intact, syringing is not performed. A specimen is obtained only if the infection has failed to respond to standard antibiotic therapy. A cotton ball should not be placed in the ear canal to absorb the drainage.

A patient who is human immunodeficiency virus (HIV)-infected has a CD4+ cell count of 400/µL. Which factor is most important for the nurse to determine before the initiation of antiretroviral therapy (ART) for this patient? a. HIV genotype and phenotype b. Patient's social support system c. Potential medication side effects d. Patient's ability to comply with ART schedule

ANS: D Drug resistance develops quickly unless the patient takes ART medications on a strict, regular schedule. In addition, drug resistance endangers both the patient and the community. The other information is also important to consider, but patients who are unable to manage and follow a complex drug treatment regimen should not be considered for ART

(Nclex question) The nurse teaches a female client who has cystitis methods to relieve her discomfort until the antibiotic takes effect. Which of the following responses by the client would indicate that she understands the nurse's instructions? A. "I will place ice packs on my perineum." B. "I will take hot tub baths." C. "I will drink a cup of warm tea every hour." D. "I will void every 5 to 6 hours."

B. "I will take hot tub baths." Hot tub baths promote relaxation and help relieve urgency, discomfort, and spasm. Applying heat to the perineum is more helpful than cold because heat reduces inflammation. Although liberal fluid intake should be encouraged, caffeinated beverages, such as tea, coffee, and cola, can be irritating to the bladder and should be avoided. Voiding at least every 2 to 3 hours should be encouraged because it reduces urinary stasis.

(NCLEX question) You're providing education to a patient with severe ulcerative colitis about Adalimumab. Which statement by the patient is CORRECT?* A. "This medication is used as first-line treatment for ulcerative colitis." B. "My physician will order a TB skin test before I start taking this medication." C. "This medication works by increasing the tumor necrosis factor protein which helps decrease inflammation." D. "This medication is a corticosteroid. Therefore, I need to monitor my blood glucose levels regularly."

B. "My physician will order a TB skin test before I start taking this medication." Before starting Adalimumab, the physican may order the patient to be checked for TB. Adalimumab is a immunomodulator (NOT corticosteriod) that suppresses the immune system by BLOCKING (not increasing) the tumor necrosis factor protein which helps decrease inflammation. Therefore, the patient is at risk for developing infections such as TB (tuberculosis). In addition, if the patient has or had TB, this medication could exacerbate the disease. This medication is used for only severe cases (NOT first-line treatment).

(Nclex question) A client has been prescribed nitrofurantoin (Macrodantin) for treatment of a lower urinary tract infection. Which of the following instructions should the nurse include when teaching the client how to take this medication? Select all that apply. A. "Take the medication on an empty stomach." B. "Your urine may become brown in color." C. "Increase your fluid intake." D. "Take the medication until your symptoms subside." E. "Take the medication with an antacid to decrease gastrointestinal distress."

B. "Your urine may become brown in color." C. "Increase your fluid intake." Clients who are taking nitrofurantoin (Macrodantin) should be instructed to take the medication with meals and to increase their fluid intake to minimize gastrointestinal distress. The urine may become brown in color. Although this change is harmless, clients need to be prepared for this color change. The client should be instructed to take the full prescription and not to stop taking the drug because symptoms have subsided. The medication should not be taken with antacids as this may interfere with the drug's absorption.

When is the first dose of Rotarix vaccine administered in infants? A. Birth to 6 weeks B. 6-12 weeks C. 12-18 weeks D. 18-24 weeks

B. 6-12 weeks

(NCLEX question) **You're educating a group of outpatients about signs and symptoms of ulcerative colitis. Which of the following are NOT typical signs and symptoms of ulcerative colitis? SELECT-ALL-THAT-APPLY:* A. Rectal Bleeding B. Abdominal mass C. Bloody diarrhea D. Fistulae E. Extreme Hungry F. Anemia

B. Abdominal mass D. Fistulae E. Extreme Hungry Rectal bleeding, bloody diarrhea, and anemia are present in ulcerative colitis. However, an abdominal mass or fistulae tends to be present with Crohn's Disease. Loss of appetite rather than extreme hungry presents in ulcerative colitis.

An infant who has clinical manifestations of AOM is brought to an outpatient facility by his parent. The nurse should recognize that which of the following factors places the infant at risk for otitis media? (Select all that apply.) A. Breastfeeding without formula supplementation. B. Attends day care 4 days per week. C. Immunizations are up to date. D. History of cleft palate repair. E. Parents smoke cigarettes outside.

B. Attends day care 4 days per week. D. History of cleft palate repair. E. Parents smoke cigarettes outside.

(Power points) Which statements are true regarding osteoarthritis (select all that apply) A. Develops due to the deterioration of the synovium of the bone. B. Can lead to bone break down and osteophytes formation (bone spurs) C. Most common form of joint disease in North America D. Part of normal aging process E. Begins between ages of 20 and 40 years of age and symptoms usually appear after the age of 50 or 60 years

B. Can lead to bone break down and osteophytes formation (bone spurs) C. Most common form of joint disease in North America E. Begins between ages of 20 and 40 years of age and symptoms usually appear after the age of 50 or 60 years Develops due to the deterioration of the HYALINE CARTILAGE (not synovium) of the bone NOT part of the normal aging process

(NCLEX question) A patient with a urinary tract infection is taking Bactrim (Sulfamethoxazole/Trimethoprim). As the nurse you know it is important that the patient consumes 2.5 to 3 L of fluid per day to prevent which of the following complications?* A. Brown urine B. Crystalluria C. Renal Stenosis D. Renal Calculi

B. Crystalluria Antibiotics called sulfonamides such as Bactrim (Sulfamethoxazole/Trimethoprim) can cause crystalluria. This complication tends to happen when the urine is concentrated. Therefore, the patient should consume 2.5 to 3L of fluid per day to keep the urine diluted.

(Self assessment question) The inflammatory process is an anticipated response to tissue injury that produces which desirable outcomes? (Select all that apply.) A. Initial death of tissues B. Eradication of dead tissue C. Formation of scar tissue D. Acute inflammation E. Chronic inflammation

B. Eradication of dead tissue D. Acute inflammation Inflammation is a normal and protective response to injury. Four outcomes are possible, two of which are desirable: acute inflammation and eradication of dead tissue. This process returns tissues to their previously uninjured state. The formation of scar tissue occurs when damaged cells cannot be adequately repaired. This is not the most desirable outcome. Chronic inflammation results when tissue destruction continues and is not a desirable outcome. Initial death of tissue leads to death of the host, a very undesirable outcome.

(Self assessment question) The nurse is completing an admission assessment of a new patient to the unit. The nurse notes a long, thin, fading scar on the patient's abdomen in the right lower quadrant. What is the best explanation for the scar's appearance? A. Optimal functioning of the inflammatory process after an injury B. Fibrous tissue replacing damaged tissue when injury is extensive C. The development of chronic inflammation D. A surgical incision

B. Fibrous tissue replacing damaged tissue when injury is extensive Scar tissue, or fibrous repair of damaged tissue, occurs when an area is damaged too extensively for the body to replace damaged tissue with identically functioning tissue after removal of injurious agents and pathogens. Optimal functioning of the inflammatory process will result in regeneration of tissue that functions identically to the damaged and replaced tissue. Chronic inflammation can result in fibrous, or scar, tissue, but that scar tissue production is continuous as the inflammation continues. Fibrous tissue production can result from many different kinds of injuries, not just surgical wounds.

(NCLEX question) During a head-to-toe assessment of a patient with osteoarthritis, you note bony outgrowths on the distal interphalangeal joints. You document these findings as: A. Bouchard's Nodes B. Heberden's Nodes C. Neurofibromatosis D. Dermatofibromas

B. Heberden's Nodes Bony outgrowths found on the DISTAL interphalangeal joint (closest to the fingernail and furthest away from the body) is called Heberden's Node. If the bony outgrowth was found on the PROXIMAL interphalangeal joint (middle joint of the finger...closest to the body) it is called Bouchard's Node.

(NCLEX question) You receive your patient back from radiology. The patient had an x-ray of the hips and knees for the evaluation of possible osteoarthritis. What findings would appear on the x-ray if osteoarthritis was present? Select-all-that-apply: A. Increased joint space B. Osteophytes C. Sclerosis of the bone D. Abnormal sites of hyaline cartilage

B. Osteophytes C. Sclerosis of the bone The answers are B and C. The joint space would be DECREASED not increased in OA. In addition, an x-ray cannot show hyaline cartilage...therefore, the cartilage cannot be assessed on an x-ray. The radiologist would be looking for osteophytes (bone spurs), sclerosis of the bone (abnormal hardening of the bones), and decreased joint space.

A client is experiencing an exacerbation of ulcerative colitis. A low-residue, high-protein diet and IV fluids with vitamins have been prescribed. When implementing these prescriptions, which goal is the nurse trying to achieve? A. Reduce gastric acidity B. Reduce colonic irritation C. Reduce intestinal absorption D. Reduce bowel infection rate

B. Reduce colonic irritation A low-residue diet is designed to reduce colonic irritation, motility, and spasticity. Reduction of gastric acidity is the aim of bland diets used in the treatment of gastric ulcers. Reducing colonic irritation, motility, and spasticity hopefully will increase, not reduce, intestinal absorption. This diet is to allow the bowel to rest, not to reduce infection rates.

(power points) Collaborate care for an exaggerated immune response involves which of the following? (select all that apply) A. Prevent opportunistic infections B. Remove exposure (if possible) C. Airway support (if anaphylaxis occurs) D. Monitor and treat opportunistic infections E. Pharmacotherapy

B. Remove exposure (if possible) C. Airway support (if anaphylaxis occurs) E. Pharmacotherapy Exaggerated Immune Response Remove exposure (if possible) Airway support (if anaphylaxis occurs) Pharmacotherapy Immunodeficiency Monitor immune function Nutrition Prevent opportunistic infections Monitor and treat opportunistic infections Drug therapy

A nurse is assessing an infant. Which of the following findings are clinical manifestations of acute otitis media? (Select all that apply.) A. Decreased pain in the supine position B. Rolling head side to side C. Loss of appetite D. Increased sensitivity to sound E. Crying

B. Rolling head side to side C. Loss of appetite E. Crying

A nurse is counseling the family of a child with AIDS. What is the most important concern that the nurse should discuss with the parents? A. Risk for injury B. Susceptibility to infection C. Inadequate nutritional intake D. Altered growth and development

B. Susceptibility to infection Children with AIDS have a dysfunction of the immune system (depressed or ineffective T lymphocytes, B lymphocytes, and immunoglobulins) and are susceptible to opportunistic infections. All children are subject to injury because of their curiosity, inexperience, and lack of judgment. Although inadequate nutrition can be a problem for children with AIDS, the prevention of infection is the priority. Although children with AIDS are usually small for age, altered growth and development is not as life threatening as an infection.

(NCLEX question) A patient with osteoarthritis has finished their first physical therapy session. As the nurse you want to evaluate the patient's understanding of the type of exercises they should be performing regularly at home as self-management. Select all the appropriate types of exercise stated by the patient: A. Jogging B. Water aerobics C. Weight Lifting D. Tennis E. Walking

B. Water aerobics C. Weight Lifting E. Walking The answers are B, C, E. The patient wants to perform exercises that are low impact like: walking, water aerobics, stationary bike riding along with strengthen training (lifting weights: helps strengthen muscles around the joint), ROM: improves the mobility of the joint and decreases stiffness. It is important patients with OA avoid high impact exercises that will increase stress on weight bearing joints such as running/jogging, jump rope, tennis, or any type of exercise with both feet off the ground.

(Self assessment question) The nurse is reviewing the erythrocyte sedimentation rate (ESR) of a patient to determine which significant finding? A. Determines specific causes of inflammation. B. Identifies the location of inflammation within the body. C. Confirms the nonspecific presence of inflammation. D. Indicates a diagnosis of systemic lupus. .

C. Confirms the nonspecific presence of inflammation. An elevated ESR is indicative of the presence of inflammation in the body. Proteins produced during the inflammatory process adhere to red blood cells, causing them to be heavier and settle out of blood samples at a faster rate than normal. The ESR does not identify specific causes of inflammation and does not determine a specific location of inflammation. The ESR is a nonspecific indicator of inflammation

(NCLEX question) The physician orders a urine culture on your patient in room 5505 with a urinary tract infection. In addition, the patient is ordered to start IV Bactrim (Sulfamethoxazole/Trimethoprim). How will you proceed with following this order?* A. First, hang the antibiotic, and then collect the urine culture. B. First, hang the antibiotic and when the antibiotic is finished infusing collect the urine culture. C. First, collect the urine culture, and then hang the antibiotic. D. First, collect the urine culture and then hold the dose of the antibiotic until the urine culture is back from the lab.

C. First, collect the urine culture, and then hang the antibiotic It is very important to collect the urine culture FIRST and then immediately hang the antibiotic. If the antibiotic is hung first it will decrease the lab's ability to properly identify the bacteria growing in the urine (hence the antibiotic is fighting the infection). It takes approximately 2 days for a urine culture result to come back. Therefore, antibiotic therapy should not be held. The patient needs treatment to prevent the infection from spreading.

(power points) Which are clinical manifestations of chronic OM A. Otalgia B. Fever C. Hearing loss D. Difficulty communicating E. Possible feeling of fullness F. Tinnitus G. Vertigo H. Purulent discharge

C. Hearing loss D. Difficulty communicating E. Possible feeling of fullness F. Tinnitus G. Vertigo

(in class discussion) What clinical indicator will the nurse most likely identify when assessing a patient with pyrexia? A. Dyspnea B. Pericordial Pain C. Increased pulse rate D. Elevated blood pressure

C. Increased pulse rate

nurse provides dietary teaching for a client with an acute exacerbation of ulcerative colitis, and afterward the client makes a list of foods that can be included on the diet. Which food choices indicate that the teaching by the nurse is effective? Select all that apply. A. Orange juice B. Creamed soup C. Jelly sandwich D. Lean roast beef E. Scrambled eggs A jelly sandwich is low in residue and therefore is less irritating to the colon than other foods. Lean roast beef is low in residue and therefore is less irritating to the colon than other foods. Eggs are low in residue and therefore are less irritating to the colon than other foods. Orange juice contains cellulose (fiber), which is not absorbed and irritates the colon. Milk in creamed soup contains lactose, which is irritating to the colon.

C. Jelly sandwich D. Lean roast beef E. Scrambled eggs A jelly sandwich is low in residue and therefore is less irritating to the colon than other foods. Lean roast beef is low in residue and therefore is less irritating to the colon than other foods. Eggs are low in residue and therefore are less irritating to the colon than other foods. Orange juice contains cellulose (fiber), which is not absorbed and irritates the colon. Milk in creamed soup contains lactose, which is irritating to the colon.

(Self assessment question) The production of which immune cells are increased following exposure to viral antigens? A. Basophils B. Eosinophils C. Lymphocytes D.Neutrophils

C. Lymphocytes Lymphocytes are most prominent in inflammatory responses to viral antigens. Basophils are elevated during chronic inflammation/infections, eosinophils during parasitic infections and allergic reactions, and neutrophils during bacterial infections.

(Self assessment question) Why is inflammation often confused with infection? A. Prostaglandin hormone mediates both. B. Purulent drainage is frequently present. C. Many pathophysiologic processes are shared. D. They produce comparable immune dysfunction.

C. Many pathophysiologic processes are shared. Inflammation and infection are commonly confused because many of the pathophysiologic processes associated with one are also found with the other; they overlap. Option A is incorrect because prostaglandin is a proinflammatory hormone that mediates late stages of acute inflammation. Infections are not mediated by such hormones. They are only involved in infections because inflammation occurs when infection occurs. Option B is incorrect because purulent drainage is a sign of infection, but does not occur from inflammation. Option D is incorrect because infection can overwhelm and damage the immune system very quickly (septic shock). Acute inflammation is a protective response. Chronic inflammation, over time, does damage tissue and can be detrimental to the immune system. However, these processes are not comparable.

Which type of immunity is acquired through the transfer of colostrum from the mother to the child? A. Natural active immunity B. Artificial active immunity C. Natural passive immunity D. Artificial passive immunity

C. Natural passive immunity Natural passive immunity is acquired through the transfer of colostrum from the mother to the child. Natural active immunity is acquired when there is a natural contact with an antigen through a clinical infection. Artificial active immunity is acquired through immunization with an antigen. Artificial passive immunity is acquired by injecting serum from an immune human.

Med surg Patient complains of fullness of the ear, a "plugged" feeling or popping, and decreased hearing. Patient does not experience pain, fever, or discharge from the ear. What does the nurse suspect? A. OM B. AOM C. OME D. MME

C. OME

(NCLEX question) A patient newly diagnosed with osteoarthritis asks about the medication treatments for their condition. Which medication is NOT typically prescribed for OA? A. NSAIDs B. Topical Creams C. Oral corticosteroids D. Acetaminophen (Tylenol)

C. Oral corticosteroids The answer is C. Intra-articular corticosteroids (an injection in the joint) are commonly prescribed rather than oral corticosteroids. Remember OA in within the joint...not systemic so oral corticosteroids are not as effective. All the other medications listed are prescribed in OA.

Which of these is the most common opportunistic infection in children with HIV infection? A. TB B. Candidates esophagitis C. Pneumocystis carinii pneumonia D. Herpes simplex virus

C. Pneumocystis carinii pneumonia TB is most common in locations where access to medications are low.

(NCLEX question) The client with cystitis is given a prescription for phenazopyridine hydrochloride (Pyridium). The nurse should teach the client that this drug is used to treat urinary tract infections by: A. Releasing formaldehyde and providing bacteriostatic action. B. Potentiating the action of the antibiotic. C. Providing an analgesic effect on the bladder mucosa. D. Preventing the crystallization that can occur with sulfa drugs.

C. Providing an analgesic effect on the bladder mucosa. Note: The client should be told that phenazopyridine hydrochloride (Pyridium) turns the urine a bright orange-red, which may stain underwear

A nurse is caring for a 2-year-old child who has had three ear infections in the past 5 months. The nurse should know that the child is at risk for developing which of the following as a long-term complication? A. Balace difficulties B. Prolonged hearing loss C. Speech delays D. Mastoiditis

C. Speech delays

Which type of vaccines triggers the recipient's immune system to produce antitoxins? A. Live vaccines B. Killed vaccines C. Toxoid vaccines D. Specific immune globulins

C. Toxoid vaccines Toxoids are a nontoxic form of bacterial toxins that induce the formation of antitoxins by the recipient's immune system. Examples of these types of vaccines include tetanus toxoid and diphtheria toxoid. Both live and killed vaccines induce the body's immune system to produce antibodies, making the individual actively immune to the microbes. Specific immune globulins are high concentration of antibodies prepared from donated blood directed against specific antigens.

Which of the following is the primary complication of a middle ear infection A. sensorineural hearing loss B. vertigo C. perforation of the ear drum D. tempanosclerosis

C. perforation of the ear drum

Several clients at the clinic have just been diagnosed with UTIs. Which clients may need to be hospitalized? ( select all that apply) Postmenopausal woman Client with a long-term indwelling catheter Client with diabetes Immunosuppressed client Pregnant client

Client with a long-term indwelling catheter Client with diabetes Immunosuppressed client Pregnant client

During HIV infection a. the virus replicates mainly in B-cells before spreading to CD4+ T cells. b. infection of monocytes may occur, but antibodies quickly destroy these cells. c. the immune system is impaired predominantly by the eventual widespread destruction of CD4+ T cells. d. a long period of dormancy develops during which HIV cannot be found in the blood and there is little viral replication

Correct answer: c Rationale: Immune dysfunction in HIV disease is caused predominantly by damage to and destruction of CD4+ T cells (i.e., T helper cells or CD4+ T lymphocytes).

(Self assessment question) A patient comes to a clinic with a chief complaint of, "My left arm is red and swollen. It hurts badly enough that I couldn't go to work today." The physician orders computer-assisted tomography (CT) scanning of the left upper extremity. The nurse knows the patient understands the reason for the procedure when he states A. "I need to have this done because my arm is broken." B. "The doctor wants me to have this so that the pain will stop." C. "This will tell you what I did to my elbow because I really don't know what happened." D "This test will help to better determine where the injury actually is and how severe it is."

D "This test will help to better determine where the injury actually is and how severe it is." Radiographic imaging studies such as CT scans help to determine the location and extent of inflammation within the body. The CT scan will help with diagnosis. The diagnosis is not predetermined. CT scanning does not alleviate pain. Radiography does not necessarily determine a cause of an injury.

The parents of a 4-month-old infant with a diagnosis of acute otitis media and fever ask the nurse about the use of antibiotics to treat this condition. What is the best response by the nurse? A. "Antiinflammatory medications are recommended for this condition." B. "Typically antiviral medications are given to treat acute otitis media." C. "Current practice is to wait 72 hours to see whether the condition resolves." D. "Antibiotics are recommended for infants younger than 6 months with acute otitis media."

D. "Antibiotics are recommended for infants younger than 6 months with acute otitis media." All cases of acute otitis media (AOM) in infants younger than 6 months should be treated with antibiotics because of their immature immune systems and the potential for infection with bacteria. Current literature indicates that waiting up to 72 hours for spontaneous resolution is safe and appropriate management of AOM in healthy infants older than 6 months and children. However, the watchful waiting approach is not recommended for children younger than 2 years of age who have persistent acute symptoms of fever and severe ear pain. Antiviral or antiinflammatory medications would not be recommended in an acute case of otitis media.

(in class discussion) Which of the following patients is at higher risk for inflammatory reactions? A. 2 year old girl with a healthy diet B.38 year old man who is obese C. 54 year old woman in menopause D. 79 year old man with diabetes

D. 79 year old man with diabetes

(Self assessment question) Which of the following patients is at higher risk for inflammatory reactions? A. 2-year-old girl with a healthy diet B. 38-year-old man who is obese C. 54-year-old woman in menopause D. 79-year-old man with diabetes

D. 79-year-old man with diabetes The 79-year-old man is at highest risk for inflammatory reactions among these patients for two reasons, his age and having diabetes. The risk would be high during the first year of life, but this 2-year-old girl has gotten beyond this risk period and she also has the positive factor of a healthy diet. The 38-year-old man is not in a high-risk category because of age but is because of obesity. Although a 54-year-old woman is getting older, being in menopause does not increase the risk for inflammatory reactions.

(NCLEX question) You're assessing your patients during morning rounding. Which patient below is at MOST risk for developing a urinary tract infection?* A. A 25 year old patient who finished a regime of antibiotics for strep throat 10 weeks ago. B. A 55 year old female who is post-opt day 7 from hip surgery. C. A 68 year old male who is experiencing nausea and vomiting. D. A 87 year old female with Alzheimer's disease who is experiencing bowel incontinence.

D. A 87 year old female with Alzheimer's disease who is experiencing bowel incontinence. This patient has many risks factors for developing a UTI. The patient is postmenopausal which leads to flora changes in the vaginal area. This can increase the risk of developing a UTI. In addition, bowel incontinence increases the risk of a UTI due to the anatomy of the female (short urethra) and the close proximity between the rectum to the urethra. Also, patients with Alzheimer's disease may experience bladder retention due to the inability to communicate the need to void which increases the amount of time the urine is left in the bladder. Option A is wrong because although antibiotics can increase the risk of developing a UTI the patient finished the antibiotics 10 weeks ago. Options B and C are wrong because they do not provide enough information to determine if the patients are at risk for a UTI.

(NCLEX question) A patient diagnosed with pancolitis is experiencing extreme abdominal distension, pain 10 on 1-10 scale in the abdomen, temperature of 103.6 'F, HR 120, and profuse diarrhea. What complication due you suspect the pain is experiencing?* A. Fistulae B. Stricture C. Bowel obstruction D. Toxic megacolon

D. Toxic megacolon Pancolitis affects all the colon and is a very severe form of ulcerative colon. The patient is at risk for toxic megacolon. In toxic megacolon, the large intestine dilates due to the overwhelming inflammation. The large intestine is unable to function properly and becomes paralyzed. Typical signs and symptoms of toxic megacolon include: abdominal distention, fever, diarrhea, abdominal pain, dehydration, and tachycardia.

According to the Healthcare Personnel Vaccination Recommendations, what meningococcal conjugate vaccine dose should a nurse administer to a 12-year-old with an HIV infection? A. Single initial dose and a booster dose 3 years later B. Single initial dose and a booster dose 5 years later C. Single initial dose and a booster dose 7 years later D. Two initial doses and a booster dose at 16 years old

D. Two initial doses and a booster dose at 16 years old A 12-year-old with HIV would require two primary meningococcal conjugate vaccine delivered two months apart initially and a booster dose at the age of 16 years old. The client would require two initial doses, not a single initial dose, and a booster at 16 years old, not 3, 5, or 7 years later.

What is the function of a client's natural killer cells? A. Secrete immunoglobulins in response to the presence of a specific antigen B. Heighten selectively and destroy non-self cells, including virally infected cells C. Enhance immune activity through secretion of various factors, cytokines, and lymphokines D.Attack non-selectively on non-self cells, especially mutated and malignant cells

D.Attack non-selectively on non-self cells, especially mutated and malignant cells Natural killer cells attack non-selectively on non-self cells, especially body cells that have undergone mutation and become malignant. Plasma cells secrete immunoglobulins in response to the presence of a specific antigen. Cytotoxic T-cells attack selectively and destroy non-self cells, including virally infected cells. Helper T-cells enhance immune activity through secretion of various factors, cytokines, and lymphokines.

Which vaccination is given to young children to provide protection against tetanus and diphtheria but not pertussis? Td DT DTaP Tdap

DT is given to children to provide protection from both tetanus and diphtheria. Td is used as a booster dose to protect adolescents and adults from tetanus and diphtheria. DTaP is given to children to provide protection from tetanus, diphtheria, and acellular pertussis. Tdap is used as a booster dose to protect adolescents and adults from tetanus, diphtheria, and acellular pertussis.

The urinalysis report of a client reveals pH to be 6, turbidity-cloudy, specific gravity of 1.02, and 0.7 mg/dL of proteins. What does the primary healthcare provider infer from the findings? Infection Glomerular disorder Acid-base imbalance Decreased kidney perfusion

Infection Cloudy urine indicates infection, sedimentation, or high levels of protein in the urine. Therefore the primary healthcare provider concludes that the client has an infection. Increased amounts of proteins in the urine indicate glomerular disorders. The normal levels of protein in the urine range between 0-0.8 mg/dL. Since the client's report shows 0.7 mg/dL of urinary proteins, this is normal. Changes in the pH of urine indicate acid-base imbalance. The average pH of urine is 6. Therefore the client's urinary pH is normal. Decreased kidney perfusion is characterized by increased specific gravity of the urine. The normal specific gravity of urine ranges between 1.000-1.040. The client's urine has a specific gravity of 1.02, which is a normal value

A nurse is assessing two clients. One client has ulcerative colitis, and the other client has Crohn disease. Which is more likely to be identified in the client with ulcerative colitis than in the client with Crohn disease? Inclusion of transmural involvement of the small bowel wall Higher occurrence of fistulas and abscesses from changes in the bowel wall Pathology beginning proximally with intermittent plaques found along the colon Involvement starting distally with rectal bleeding that spreads continuously up the colon

Involvement starting distally with rectal bleeding that spreads continuously up the colon Ulcerative colitis involvement starts distally with rectal bleeding that spreads continuously up the colon to the cecum. In ulcerative colitis, pathology usually is in the descending colon; in Crohn disease, it is primarily in the terminal ileum, cecum, and ascending colon. Ulcerative colitis, as the name implies, affects the colon, not the small intestine. Intermittent areas of pathology occur in Crohn. In ulcerative colitis, the pathology is in the inner layer and does not extend throughout the entire bowel wall; therefore, abscesses and fistulas are rare. Abscesses and fistulas occur more frequently in Crohn disease.

Natural active natural passive

Naturally Acquired Active - develops after introduction of foreign antigen resulting in formation of antibodies or sensitized t-lymphocytes When you actually get the disease Obtained naturally through the immune response to exposure to infectious pathogens such as varicella-zoster virgin rus Passive - occurs by the introduction of antibodies or from a natural route From a mother to her fetus through placental blood transference or through colostrum transfer during breastfeeding Mom passes immunity to fetus Artificially Acquired Active - the immune response to an immunization Example: vaccines (measles has come back because they are not vaccinating anymore out west) Flu shot (pathogens are dead) Passive - such as a transfusion of immunoglobulin (Ig) When you get a IVIg or injection of Ig

A nurse is providing dietary teaching for a client with celiac disease. Which foods should the nurse teach the client to avoid when following a gluten-free diet? Select all that apply. a. Rye b. Oats c. Rice d. Corn e. Wheat

Rye, oats, and wheat should be avoided because they are irritating to the gastrointestinal mucosa. Gluten is not found in rice or corn; therefore, these items do not have to be avoided.

Which type of immune preparation, made from donated blood, contains antibodies that provide passive immunity? Toxoid Killed vaccine Live attenuated vaccine Specific immune globulin

Specific immune globulin Specific immune globulins contain a high concentration of antibodies directed at specific antigens. Toxoid vaccines contain a bacterial toxin that has been changed to a nontoxic form. Killed vaccines contain killed microbes or isolated microbes. Live attenuated vaccines are composed of live microbes that have been weakened or rendered completely avirulent.

(NCLEX question) True or False: Ulcerative colitis is a type of inflammatory bowel disease that causes inflammation and ulcer formation in the inner lining of the small intestine, specifically the terminal ileum.*

The answer is FALSE: Ulcerative colitis is a type of inflammatory bowel disease that causes inflammation and ulcer formation in the inner lining of the LARGE (not small) intestine. The inflammation tends to start in the rectum and spreads throughout the colon. The small intestine is usually not involved.

The nurse cares for a patient infected with human immunodeficiency virus (HIV) who has just been diagnosed with asymptomatic chronic HIV infection. Which prophylactic measures will the nurse include in the plan of care (select all that apply)? a. Hepatitis B vaccine b. Pneumococcal vaccine c. Influenza virus vaccine d. Trimethoprim-sulfamethoxazole e. Varicella zoster immune globulin

a. Hepatitis B vaccine b. Pneumococcal vaccine c. Influenza virus vaccine Asymptomatic chronic HIV infection is a stage between acute HIV infection and a diagnosis of symptomatic chronic HIV infection. Although called asymptomatic, symptoms (e.g., fatigue, headache, low-grade fever, night sweats) often occur. Prevention of other infections is an important intervention in patients who are HIV positive, and these vaccines are recommended as soon as the HIV infection is diagnosed. Antibiotics and immune globulin are used to prevent and treat infections that occur later in the course of the disease when the CD4+ counts have dropped or when infection has occurred.

Which statements accurately describe HIV infection (select all that apply)? a. Untreated HIV infection has a predictable pattern of progression. b. Late chronic HIV infection is called acquired immunodeficiency syndrome (AIDS). c. Untreated HIV infection can remain in the early chronic stage for a decade or more. d. Untreated HIV infection usually remains in the early chronic stage for 1 year or less. e. Opportunistic diseases occur more often when the CD4+ T cell count is high and the viral load is low.

a. Untreated HIV infection has a predictable pattern of progression. b. Late chronic HIV infection is called acquired immunodeficiency syndrome (AIDS). c. Untreated HIV infection can remain in the early chronic stage for a decade or more.

A pregnant woman with a history of asymptomatic chronic human immunodeficiency virus (HIV) infection is seen at the clinic. The patient states, "I am very nervous about making my baby sick." Which information will the nurse include when teaching the patient? a. The antiretroviral medications used to treat HIV infection are teratogenic. b. Most infants born to HIV-positive mothers are not infected with the virus. c. Because she is at an early stage of HIV infection, the infant will not contract HIV. d. It is likely that her newborn will become infected with HIV unless she uses antiretroviral therapy (ART).

b. Most infants born to HIV-positive mothers are not infected with the virus. ANS: B Only 25% of infants born to HIV-positive mothers develop HIV infection, even when the mother does not use ART during pregnancy. The percentage drops to 2% when ART is used. Perinatal transmission can occur at any stage of HIV infection (although it is less likely to occur when the viral load is lower). ART can safely be used in pregnancy, although some ART drugs should be avoided.

When assessing the patient who has a lower urinary tract infection (UTI), the nurse will initially ask about a. flank pain. b. pain with urination. c. poor urine output. d. nausea.

b. pain with urination. Rationale: Pain with urination is a common symptom of a lower UTI. Urine output does not decrease, but frequency may be experienced. Flank pain and nausea are associated with an upper UTI.

A 34-year-old patient with diabetes mellitus is hospitalized with fever, anorexia, and confusion. The health care provider suspects acute pyelonephritis when the urinalysis reveals bacteriuria. An appropriate collaborative problem identified by the nurse for the patient is potential complication a. hydronephrosis. b. urosepsis. c. acute renal failure. d. chronic pyelonephritis.

b. urosepsis. Rationale: Infection can easily spread from the kidney to the circulation, causing urosepsis. A patient with a urinary tract obstruction will be at risk for hydronephrosis. Acute renal failure is not a common complication of acute pyelonephritis unless urosepsis and septic shock develop. Chronic pyelonephritis may occur after recurrent upper UTIs.

A patient who has a positive test for human immunodeficiency virus (HIV) antibodies is admitted to the hospital with Pneumocystis jiroveci pneumonia (PCP) and a CD4+ T-cell count of less than 200 cells/L. Based on diagnostic criteria established by the Centers for Disease Control and Prevention (CDC), which statement by the nurse is correct? a. "The patient meets the criteria for a diagnosis of an acute HIV infection." b. "The patient will be diagnosed with asymptomatic chronic HIV infection." c. "The patient has developed acquired immunodeficiency syndrome (AIDS)." d. "The patient will develop symptomatic chronic HIV infection in less than a year."

c. "The patient has developed acquired immunodeficiency syndrome (AIDS)." Development of PCP meets the diagnostic criterion for AIDS. The other responses indicate earlier stages of HIV infection than is indicated by the PCP infection.

A 98-year-old patient with benign prostatic hyperplasia has a markedly distended bladder and is agitated and confused. All the following orders are received from the emergency department health care provider. Which order should the nurse act on first? a. Draw blood for blood urea nitrogen (BUN) and creatinine. b. Administer lorazepam (Ativan) 0.5 mg. c. Insert 16 French retention catheter. d. Schedule for IVP.

c. Insert 16 French retention catheter. Rationale: The patient's history and clinical manifestations are consistent with acute urinary retention, and the priority action is to relieve the retention by catheterization. The BUN and creatinine measurements can be obtained after the catheter is inserted. The patient's agitation may resolve once the bladder distention is corrected, and sedative drugs should be used cautiously in older patients. The IVP is an appropriate test, but does not need to be done urgently.

A patient with nephrotic syndrome develops flank pain. The nurse will anticipate treatment with a. antibiotics. b. antihypertensives. c. anticoagulants. d. corticosteroids.

c. anticoagulants. Rationale: Flank pain in a patient with nephrosis suggests a renal vein thrombosis, and anticoagulation is needed. Antibiotics are used to treat a patient with flank pain caused by pyelonephritis. Antihypertensives are used if the patient has high blood pressure. Corticosteroids may be used to treat nephrotic syndrome but will not resolve a thrombosis.

*A 52-year-old female patient was exposed to human immunodeficiency virus (HIV) 2 weeks ago through sharing needles with other substance users. What symptoms will the nurse teach the patient to report that would indicate the patient has developed an acute HIV infection? a. Cough, diarrhea, headaches, blurred vision, muscle fatigue b.. Night sweats, fatigue, fever, and persistent generalized lymphadenopathy c. Oropharyngeal candidiasis or thrush, vaginal candidal infection, or oral or genital herpes d. Flu-like symptoms such as fever, sore throat, swollen lymph glands, nausea, or diarrhea

d. Flu-like symptoms such as fever, sore throat, swollen lymph glands, nausea, or diarrhea Clinical manifestations of an acute infection with HIV include flu-like symptoms between 2 to 4 weeks after exposure. Early chronic HIV infection clinical manifestations are either asymptomatic or include fatigue, headache, low-grade fever, night sweats, and persistent generalized lympadenopathy. Intermediate chronic HIV infection clinical manifestations include candidal infections, shingles, oral or genital herpes, bacterial infections, Kaposi sarcoma, or oral hairy leukoplakia. Late chronic HIV infection or acquired immunodeficiency syndrome (AIDS) includes opportunistic diseases (infections and cancer).

Screening for HIV infection generally involves: a. detecting CD8+ cytotoxic T cells in saliva. b. laboratory analysis of saliva to detect CD4+ T cells c. analysis of lymph tissues for the presence of HIV RNA. d. laboratory analysis of blood to detect HIV antigen or antibody.

d. laboratory analysis of blood to detect HIV antigen or antibody.--> * patient has a negative fourth-generation test, but reports recent risky behaviors, encourage retesting in 4 to 6 weeks. so if test is negative perform risk assesment Two laboratory tests are used for monitoring HIV progression: CD4+ T cell count and viral load.
