Which foods would the nurse recommend to a client who is concerned with ensuring that her diet is not deficient in folic acid (folate)? Select all that apply. One, some, or all responses may be correct. 1 Lean ground beef 2 Milk and cheese 3 Chicken breast meat 4 Black and pinto beans 5 Enriched bread and pasta

4, 5

Which type of hepatitis virus spreads through contaminated food and water? 1 Hepatitis A virus 2 Hepatitis B virus 3 Hepatitis C virus 4 Hepatitis D virus

1 Hepatitis A virus spreads through contaminated food and water. Hepatitis B, C, and D viruses spread through contaminated needles, syringes, and blood products.

Which organism is a common opportunistic infection in a client infected with human immunodeficiency virus (HIV)? 1 Oropharyngeal candidiasis 2 Cryptosporidiosis 3 Toxoplasmosis encephalitis 4 Pneumocystis jiroveci pneumonia

1 Oropharyngeal candidiasis is the most common infection associated with HIV because the immune system can no longer control Candida fungal growth. Pneumocystis jiroveci pneumonia (PCP) is more common in a client infected with acquired immunodeficiency syndrome (AIDS). It causes tachypnea and persistent dry cough. Cryptosporidiosis, an intestinal infection caused by Cryptosporidium organisms, presents in clients with AIDS as does toxoplasmosis encephalitis, which is caused by Toxoplasma gondii and is acquired through contact with contaminated cat feces or by ingesting infected undercooked meat.

Which hormone is released from the posterior pituitary gland? 1 Oxytocin 2 Prolactin 3 Growth hormone 4 Luteinizing hormone

1 Oxytocin is released from the posterior pituitary gland, which acts on the uterus and mammary glands. Prolactin, growth hormone, and luteinizing hormone are produced by the anterior pituitary gland.

Which urinary diagnostic test does not require any dietary or activity restrictions for the client before or after the test? 1 Renal scan 2 Renal biopsy 3 Renal arteriogram 4 Concentration test

1 A renal scan does not require any dietary or activity restrictions. A renal biopsy requires bed rest for 24 hours after the procedure. A renal arteriogram requires the client to maintain bed rest with affected leg straight. A concentration test requires the client to fast after a given time in the evening.

A high school student arrives at the local blood drive center to donate blood for the first time. As the site is being prepared for needle insertion, the student becomes agitated, starts to hyperventilate, and complains of dizziness and tingling of the hands. Which would the nurse instruct the student to do? 1 Breathe into cupped hands. 2 Pant using rapid, shallow breaths. 3 Use a rapid deep-breathing pattern. 4 Hold the breath for as long as possible.

1 Breathing into cupped hands allows carbon dioxide to reenter the lungs, which will increase the serum bicarbonate level, relieving the respiratory alkalosis that is occurring as a result of hyperventilation.

Which dietary modifications help improve the nutritional status of a client with acquired immunodeficiency syndrome (AIDS)? 1 Refraining from consuming fatty foods 2 Refraining from consuming frequent meals 3 Refraining from consuming high-calorie foods 4 Refraining from consuming high-protein foods

1 Many clients with AIDS become intolerant to fat due to the disease and the antiretroviral medications. The client should be instructed to refrain from consuming fatty foods. The client should be encouraged to eat small and frequent meals to improve nutritional status. High-calorie and high-protein foods are beneficial to clients with AIDS because they provide energy and build immunity.

Which clinical manifestation is associated with hypernatremia in burns? 1 Fatigue 2 Seizures 3 Paresthesias 4 Cardiac dysrhythmias

2 Seizures are the clinical manifestation of hypernatremia in burns. Fatigue, paresthesias, and cardiac dysrhythmias are clinical manifestations of hyperkalemia.

a normal calcium level is

9-10.5

For which clinical indicator associated with a complication of portal hypertension would the nurse assess the client? a. liver abcess b. intestinal obstruction c. perforation of the duodenum hemorrhage from esophageal varices

c. The increased pressure within the portal circulatory system causes increased pressure in areas of portal systemic collateral circulation (most importantly, in the distal esophagus and proximal stomach). Hemorrhage is a possible complication. Liver abscesses may occur as a complication of intestinal infections, not portal hypertension. Intestinal obstruction may be caused by manipulation of the bowel during surgery, peritonitis, neurological disorders, or organic obstruction, not portal hypertension. Perforation of the duodenum usually is caused by peptic ulcers; it is not a direct result of portal hypertension or cirrhosis.

A client with laryngeal cancer is receiving chemotherapy. Which laboratory report is most important for the nurse to monitor when considering the effects of chemotherapy? 1 Platelets 2 Hemoglobin level 3 Red blood cell count 4 White blood cell count

4 Antineoplastic medications depress bone marrow, which results in leukopenia; the client must be protected from infection, which is a primary cause of death in the client with cancer. Platelets may decrease rapidly, but complications may be limited by infusions of platelets. Although the hemoglobin level diminishes, a transfusion with packed red blood cells (PRBCs) will alleviate the anemia. RBCs diminish slowly and may be replaced with a transfusion of PRBCs.

A client with schizophrenia takes ziprasidone. Which conditions in the client may indicate a need to discontinue the medication? Select all that apply. One, some, or all responses may be correct. a. leukoenia b. tachycardia c. hypokalemia d. hypermagnesemia e. prolonged QT interval

a, c, e Ziprasidone is a second-generation antipsychotic medication indicated for schizophrenia. The medication may cause leukopenia, hypokalemia, and hypomagnesemia. This medication may cause a prolonged QT interval, which indicates torsades de pointes. Bradycardia may occur in torsades de pointes but not tachycardia.

Which actions would the nurse take to help a client with obsessive-compulsive disorder discuss how anxiety influences feelings and the ability to function? Select all that apply. One, some, or all responses may be correct. 1 Identify manipulative behaviors. 2 Explore anxiety-provoking situations. 3 Introduce the client to socializing situations. 4 Assist the client in examining coping mechanisms. 5 Assess the quality of interpersonal relationships.

Which teaching would the nurse include for parents of an infant with phenylketonuria (PKU)? 1 Testing for PKU is done immediately after birth. 2 Cognitive impairment occurs if PKU is untreated. 3 Treatment for PKU includes lifelong medications. 4 PKU is transmitted by an autosomal dominant gene.

2 In PKU, the absence of the hepatic enzyme phenylalanine hydroxylase prevents metabolism (hydroxylation to tyrosine) of the amino acid phenylalanine. The increased fluid level of phenylalanine in the body and the alternate metabolic by-products (phenylketones) are associated with severe cognitive impairment if PKU is not identified and treated early. Testing for PKU cannot be done until after several days of milk ingestion. Medications are not part of therapy for PKU. PKU is transmitted by an autosomal recessive gene.

The nurse identifies that a client's urinary output is less than 40 mL/h over the past 3 hours. Which action would the nurse take? 1 Assess breath sounds and obtain vital signs. 2 Decrease the intravenous flow rate and increase oral fluids. 3 Insert an indwelling catheter to facilitate emptying of the bladder. 4 Check for dependent edema by assessing the lower extremities

1 The imbalance in intake and output, with a decreasing urinary output, may indicate kidney failure. The retention of excess body fluid can precipitate the development of heart failure. Assessing breath sounds and obtaining the vital signs are necessary when monitoring for these complications. In the presence of hypervolemia, oral and intravenous fluid intake should be decreased. There are no data to support a problem with the excretion of urine; the problem is with insufficient production. The insertion of a urinary retention catheter requires a health care provider's prescription. Checking for dependent edema by assessing the lower extremities is an appropriate assessment after respirations and vital signs are assessed.

Which signs would the nurse expect to observe in a client with small cell carcinoma of the lung who develops syndrome of inappropriate antidiuretic hormone (SIADH)? Select all that apply. One, some, or all responses may be correct. 1 Oliguria 2 Seizures 3 Vomiting 4 Polydipsia 5 Polyphagia

1, 2, 3 Cancerous cells of small cell lung cancer can produce antidiuretic hormone, which causes fluid retention, resulting in increased blood volume and decreased urine volume. Fluid retention associated with SIADH can cause cerebral edema, resulting in confusion and seizures. Fluid retention resulting in hyponatremia causes nausea and vomiting. The client will have nausea and vomiting, resulting in a decreased oral fluid and food intake.

Which instruction on infection prevention would the nurse include when providing discharge education to a client who received a cadaveric renal transplant? Select all that apply. One, some, or all responses may be correct. 1 Avoid eating from buffets. 2 Obtain annual flu vaccinations. 3 Perform regular hand hygiene. 4 Stay away from crowded areas. 5 Report a temperature greater than 100.5°F.

1,2,3,4,5 Clients who receive an organ transplant need to take immunosuppressant medications for the rest of their lives to prevent organ rejection. These medications put the client at increased risk for infection. The nurse would provide infection prevention teaching to the client after renal transplant, which would include instructions to avoid eating from buffets, get an annual flu vaccine, practice regular hand hygiene, and avoid crowded areas. Clients would also be instructed to report a temperature greater than 100.5°F to their health care provider as it could indicate infection or organ rejection and requires treatment.

Which immunomodulatory agent is beneficial for the treatment of clients with multiple sclerosis? 1 Interleukin 2 2 Interleukin 11 3 Beta interferon 4 Alpha interferon

The nurse understands which medication increases the risk of Reye syndrome in children? 1 Aspirin 2 Naloxone 3 Ibuprofen 4 Acetaminophen

1 Aspirin increases the risk of Reye syndrome in children. Naloxone, ibuprofen, and acetaminophen can be used, but the child should be assessed for renal and liver functioning before prescribing.

A health care provider prescribes B-complex vitamins. Which information will the nurse teach the client? 1 The vitamins may turn the urine bright yellow. 2 The daily fluid intake should be increased. 3 The vitamins should be taken on an empty stomach. 4 Taking the vitamins with a high-fat meal will increase absorption.

1 Bright yellow urine is an expected, insignificant side effect of vitamin B complex. There is no need to increase oral fluids; the client may consume the usual daily intake of fluid. Taking the vitamins on an empty stomach may precipitate nausea; therefore they should be taken with food. Vitamin B complex is a water-soluble vitamin, and excess amounts are excreted in urine. Taking the vitamins with a fatty meal will not improve absorption.

Which malnourished condition may predispose a client to secondary immunodeficiency? 1 Cachexia 2 Cirrhosis 3 Diabetes mellitus 4 Hodgkin lymphoma

1 Cachexia is a nutrition disorder that may occur because of wasting of muscle mass and weight, resulting in a secondary immunodeficiency disorder. Cirrhosis, diabetes mellitus, and Hodgkin lymphoma also lead to secondary immunodeficiency disorder, but these are not malnutrition disorders.

Which nursing actions best promote communication when obtaining a nursing history? Select all that apply. One, some, or all responses may be correct. 1 Establishing eye contact 2 Paraphrasing the client's message 3 Asking "why" and "how" questions 4 Using broad, open-ended statements 5 Reassuring the client that there is no cause for alarm 6 Asking questions that can be answered with a "yes" or "no"

1, 2, 4 Eye contact indicates to the client that the nurse is listening and interested. Paraphrasing is an effective interviewing technique; it indicates to the client that the message was heard and invites the client to elaborate further. Open-ended statements provide a milieu in which people can verbalize their problems rather than be placed in a situation of providing a forced response. Asking "why" and "how" questions can be threatening to the client, who may not have the answer to these questions. False reassurance is detrimental to the nurse-client relationship and does not promote communication. Direct questions do not open or promote communication.

Chemotherapy via regional perfusion is the treatment of choice for a client's malignant sarcoma of the liver. Which reason would the nurse provide to explain to the client why this method of medication administration probably was selected? 1 Medication therapy can be continued at home with little difficulty. 2 Larger doses of medications can be delivered to the actual site of the tumor. 3 Toxic effects of the chemotherapeutic medications are confined to the area of the tumor. 4 Combinations of medications are used to attack neoplastic cells at various stages of the cell cycle.

2 Regional perfusion therapy permits relative isolation of the tumor area and saturation with the medication(s) selected. This method of medication administration requires medical and nursing supervision and cannot be continued at home. Although toxic effects are confined mainly to the treated area, some migration may still occur. Combinations of chemotherapeutic medications are administered via intravenous or oral routes, not via regional perfusion.

Which major group of substances in human milk are of special importance to the newborn and cannot be reproduced in a bottle formula? 1 Amino acids 2 Gamma globulins 3 Essential electrolytes 4 Complex carbohydrates

2 The gamma globulin antibodies in human milk provide the infant with immunity against all or most of the pathogens that the mother has encountered. Amino acids and essential electrolytes are present in commercial formulas. Complex carbohydrates are not required by the infant.

Which complication is most likely to occur in the immediate postoperative period after a client has had a splenectomy? 1 Infection 2 Peritonitis 3 Hemorrhage 4 Intestinal obstruction

3 Because the spleen is highly vascular, hemorrhage may occur in the immediate postoperative period. Although risk for some types of infection is higher after splenectomy because of lower immunoglobulin levels, risk for immediate postoperative infection is not higher than usual after splenectomy. Peritonitis is possible after splenectomy, but it would not be apparent in the immediate postoperative period and is not a common complication. The incidence of intestinal obstruction is not higher than for other abdominal surgery, and symptoms would not be apparent in the immediate postoperative period.

A client had a laparoscopic cholecystectomy. Postoperatively, the client experiences nausea and vomiting and is admitted overnight for observation and hydration. What would the nurse include in the teaching plan when preparing this client for discharge? Select all that apply. One, some, or all responses may be correct. 1 Wash the puncture sites with strong soap and hot water daily. 2 Call the health care provider for a fever of 100°F (37.8°C) or higher more for 2 days. 3 Remove the tape strips over the puncture sites 1 week after surgery. 4 Check the puncture sites daily for redness, tenderness, swelling, heat, or drainage. 5 Ease the discomfort from the gas used to insufflate the abdomen during surgery by applying a heating pad to the left shoulder.

Which effect has resulted in the avoidance of tetracycline use in children under 8 years old? 1 Birth defects 2 Allergic responses 3 Severe nausea and vomiting 4 Permanent tooth discoloration

4 Tetracycline use in children under the age of 8 years has been discontinued because it causes permanent tooth discoloration. Birth defects, allergic responses, and severe nausea and vomiting are not prevalent reasons for the discontinuation of tetracycline medications in children under 8 years old.

Which statement will the nurse include when teaching the family of a child with asthma about peak flow meters (PFMs)? 1 "This device measures the peak amount of air that your child can inhale." 2 "This device will improve medication delivery to the lungs when it's used with an inhaler." 3 "Your child should make sure to use a short-acting bronchodilator before using the PFM." 4 "A PFM can help you identify when asthma is getting worse even before your child has symptoms."

4 The PFM is used to measure the maximal amount of exhalation. In doing this, it can identify when airway obstruction is occurring before the obstruction is sufficient to cause symptoms. PFMs are used to measure exhalation, not inhalation. PFMs are not used for medication administration. The use of a PFM should not be preceded by administration of a bronchodilator.

A client is prone to hyponatremia. Which factors would the nurse identify that can precipitate hyponatremia? Select all that apply. One, some, or all responses may be correct. a. wound drainage b. diuretic therapy c. GI suction d. parenteral infusion of 0.9% sodium chloride e. inappropriate anti-diuretic hormone (ADH) secretions

a, b, c, e Wound drainage can result in hyponatremia from loss of sodium ions. Most diuretics interfere with sodium reabsorption in the nephrons and have the side effect of hyponatremia. Gastrointestinal fluids are rich in sodium ions, which are lost by GI suction. With the syndrome of inappropriate antidiuretic hormone (SIADH), high levels of the antidiuretic hormone (ADH) are produced, causing the body to retain water instead of excreting it normally in the urine. Parenteral infusion of 0.9% sodium chloride, an isotonic solution, should be compatible with body fluids; if given in excess, it may lead to hypernatremia.

Which statements made by the client identify regulatory functions of the kidney? Select all that apply. One, some, or all responses may be correct. a. erhtropoiesis b. acid base balance c. vitamin D activation d. blood pressure control e. fluid and electrolyte balance

b, e Maintaining the acid-base balance of the body by selectively reabsorbing and secreting certain substances from the blood is a regulatory function of the kidneys. The kidneys also perform the regulatory function of electrolyte balance by regulating the reabsorption of certain electrolytes while eliminating others depending on their levels in the serum. The kidneys perform hormonal function by secreting a hormone called erythropoietin that aids in synthesis of red blood cells (erythropoiesis). Activation of vitamin D is a hormonal function of the kidneys. The kidneys perform hormonal function by secreting the hormone renin that assists in blood pressure control.
