What is the purpose of the glycosylated hemoglobin (hemoglobin A1c) test? a. Measuring fasting glucose levels. b. Monitoring long-term serum glucose control. c. Detecting acute complications of diabetes. d. Checking for hyperlipidemia.
ANS: B Glycosylated hemoglobin refers to the permanent attachment of glucose to hemoglobin molecules and reflects the average plasma glucose exposure over the life of a red blood cell (approximately 120 days). Glycosylated hemoglobin does not measure fasting, but rather glucose control over time. Glycosylated hemoglobin does not identify complications but could provide data if the patient is at risk. Glycosylated hemoglobin does not check for hyperlipidemia. REF: p. 471
A low ventilation-perfusion ratio of the lung will result in: a. increased dead space. b. shunting. c. alveolar collapse. d. bronchoconstriction.
ANS: B Hypoxemia caused by inadequate ventilation of well-perfused areas of the lung is a form of mismatching called shunting, not bronchoconstriction. Inadequate ventilation of well-perfused areas of the lung is not referred to as dead space. Alveolar collapse is called atelectasis. REF: p. 690
The predominant antibody of a typical primary immune response is: a. IgG. b. IgM. c. IgA. d. IgE.
ANS: B IgM is the largest immunoglobulin and is the first antibody produced during the initial, or primary, response to antigen. REF: p. 161
An 82-year-old female was admitted to the hospital with confusion and severe hypotension. Her body's compensatory mechanisms are increased heart rate, vasoconstriction, and movement of large volumes of interstitial fluid to the vascular compartment. What kind of shock does the nurse suspect the patient is experiencing? a. Anaphylactic b. Hypovolemic c. Neurogenic d. Septic
ANS: B In hypovolemic shock, heart rate and SVR increase, boosting both cardiac output and tissue perfusion pressures. Interstitial fluid moves into the vascular compartment. In anaphylactic shock, bronchoconstriction occurs with hypotension. In neurogenic shock, hypotension occurs, but fluid does not shift. In septic shock, interstitial fluid shift does not occur. REF: p. 642
Which of the following lab values would the nurse expect in a patient who has sustained trauma to the lungs and chest wall and is experiencing respiratory failure? a. Electrolyte imbalances b. Elevated PaCO2 c. Low hematocrit d. Elevated pH
ANS: B In respiratory failure, inadequate gas exchange occurs such that PaO2 ≤ 60 mm Hg or PaCO2 ≥ 50 mm Hg with pH ≤ 7.25. Electrolyte imbalances do not occur, but changes in blood gas values do. Hematocrit may be unaffected. pH will be decreased. REF: p. 690
Insulin is primarily regulated by: a. metabolic rate. b. serum glucose levels. c. prostaglandins. d. enzyme activation.
ANS: B Insulin secretion is promoted when blood levels of glucose rise. Insulin secretion is not only based on metabolic rate, prostaglandins, or enzyme activation but also on blood levels of glucose. REF: p. 451
A patient has been searching on the Internet about natriuretic hormones. When the patient asks the nurse what these hormones do, how should the nurse respond? Natriuretic hormones affect the balance of: a. calcium. b. sodium. c. magnesium. d. potassium.

Which organ contains prolactin-inhibiting factor's target tissue? a. Hypothalamus b. Anterior pituitary c. Mammary glands d. Posterior pituitary
ANS: B Prolactin-inhibiting factor (PIF) inhibits prolactin secretion by the anterior pituitary, not the hypothalamus, mammary glands, or posterior pituitary. REF: p. 444, Table18- 4
A 25-year-old male is in a car accident and sustains a fracture to his left femur with extensive soft tissue injury. The pain associated with the injury is related to: a. histamine. b. prostaglandins. c. vasoconstriction. d. immune complex formation.
ANS: B Prostaglandins cause increased vascular permeability, neutrophil chemotaxis, and pain by direct effects on nerves. Histamine promotes vasodilation. Prostaglandins are not associated with vasoconstriction or the immune complex formation. REF: p. 145
When considering pyelonephritis, where is the site of the infection? a. Bladder b. Renal pelvis c. Renal tubules d. Glomerulus
ANS: B Pyelonephritis is an infection of one or both upper urinary tracts (ureter, renal pelvis, and interstitium). Pyelonephritis is not associated with the bladder, renal tubules, or glomerulus. REF: p. 754
A 75-year-old reports loss of urine with cough, sneezing, or laughing. These symptoms support which diagnosis? a. Urge incontinence b. Stress incontinence c. Overflow incontinence d. Functional incontinence
ANS: B Reduced resistance is associated with the symptom of stress incontinence, which is incontinence with coughing or sneezing. Urge incontinence is the inability to hold the urine when the urge is felt. There is coordination between the contracting bladder and the external sphincter, but the detrusor is too weak to empty the bladder, resulting in urinary retention with overflow or stress incontinence. Functional incontinence is similar to overflow and is not associated with coughing. REF: p. 750, Table 30-1
A 30-year-old diagnosed with Graves disease is admitted to a hospital unit for the surgical removal of the thyroid gland.

If a patient's posterior pituitary is removed, which hormone would the nurse expect to decrease? a. PRF b. ADH c. ACTH d. Growth hormone (GH)
ANS: B The hormones ADH and oxytocin are released from the posterior pituitary gland. PRF is released by the hypothalamus. ACTH is released by the anterior pituitary. GH is released by the hypothalamus. REF: p. 448
A 10-year-old male presents with fever, lymphadenopathy, arthralgia, and nosebleeds and is diagnosed with rheumatic heart disease. While planning care, which characteristic changes should the nurse remember? a. Blood-borne organisms that adhere to the valvular surface b. Antigens that bind to the valvular lining, triggering an autoimmune response c. High fevers that damage collagen in valve leaflets d. Rheumatoid factor in the blood, stimulating valvular degeneration
ANS: B The immune response cross-reacts with molecularly similar self-antigens in heart, muscle, joints, and the brain, causing an autoimmune response resulting in diffuse, proliferative, and exudative inflammatory lesions in these tissues. It is not due to blood-borne organisms, high fevers, or rheumatoid factors. REF: p. 628
A 45-year-old presents with hypertension, anorexia, nausea and vomiting, and anemia and is diagnosed with chronic renal failure. What is the cause of this patient's anemia? a. Red blood cells being lost in the urine b. Inadequate production of erythropoietin c. Inadequate iron absorption in the gut d. Red blood cells being injured as they pass through the glomerulus
ANS: B The kidneys are inadequate in their production of erythropoietin; red cells may be lost in the urine, but it is the lack of erythropoietin that leads to anemia. The anemia is not associated with inadequate iron absorption or red cell destruction. REF: p. 764, Table 30-13
When considering hypothyroidism, the basal metabolic rate is unusually: a. high. testbanks_and_xanax b. low. c. steady. d. variable.
ANS: B The metabolic rate with hypothyroidism is low. REF: p. 469

The most common cause of pulmonary edema is: a. right heart failure. b. left heart failure. c. asthma. d. lung cancer.
ANS: B The most common cause of pulmonary edema is left-sided heart disease, not right-sided. Pulmonary edema is not commonly caused by asthma or lung cancer. REF: p. 695
Which organism does the nurse suspect is the most likely cause of empyema? a. Virus b. Staphylococcus aureus c. Fungus d. Moraxella catarrhalis
ANS: B The most likely cause of empyema is Staphylococcus aureus; it is not due to a virus. Empyema is not due to Moraxella catarrhalis or to a fungal infection. REF: p. 692
The onset of anaphylactic shock is usually: a. mild. b. sudden and life threatening. c. delayed by several hours. d. delayed by 24 hours.
ANS: B The onset of anaphylactic shock is usually sudden and life threatening, not mild or delayed. REF: p. 644
A 20-year-old underwent an echocardiogram to assess chest pain. Results revealed a congenital defect in the papillary muscles. Which of the following would the nurse expect to occur? a. Closure of the semilunar valve b. Backward expulsion of the atrioventricular valves c. Closure of the atrioventricular valve d. Backward expulsion of the semilunar valves
ANS: B The papillary muscles are extensions of the myocardium that pull the cusps together and downward at the onset of ventricular contraction, thus preventing their backward expulsion into the atria. Defects in the papillary muscles would not affect either the semilunar or atrioventricular valves. REF: p. 572
What causes the chronic microvascular and macrovascular complications of DM? a. Pancreatic changes b. Hyperglycemia c. Ketone toxicity d. Hyperinsulinemia
ANS: B The underlying cause of the microvascular and macrovascular diseases is related to hyperglycemia, not pancreatic changes, ketone toxicity, or hyperinsulinemia. REF: p. 478
A 50-year-old presents with hypotension, hypoxemia, and tracheal deviation to the left. Tests reveal that the air pressure in the pleural cavity exceeds barometric pressure in the atmosphere. Based upon these assessment findings, what does the nurse suspect the patient is experiencing? a. Pleural effusion b. Tension pneumothorax c. Open pneumothorax d. Transudative pneumothorax
ANS: B Tracheal deviation suggests tension pneumothorax, not pleural effusion. With an open pneumothorax, a sucking sound would be heard without tracheal deviation. Tracheal deviation suggests a tension, not transudative pneumothorax. REF: p. 692
A 35-year-old presents with pulmonary hypertension and is diagnosed as being in right heart failure. Which is the most likely cause of this condition? a. Aortic stenosis b. Tricuspid regurgitation c. Aortic regurgitation d. Mitral regurgitation
ANS: B Tricuspid regurgitation leads to volume overload in the right atrium and ventricle, increased systemic venous blood pressure, and right heart failure. Aortic stenosis is manifested by narrowed pulse pressure. Aortic regurgitation is manifested by widened pulse pressure resulting from increased stroke volume and diastolic backflow. Mitral regurgitation is manifested by heart failure but not pulmonary hypertension. REF: p. 627
A 55-year-old presents reporting urinary retention. Tests reveal a lower urinary tract obstruction. Which of the following is of most concern to the nurse? a. Vesicoureteral reflux and pyelonephritis b. Formation of renal calculi c. Glomerulonephritis d. Increased bladder compliance
ANS: B Urine stasis occurs with urinary tract obstruction and can lead to the formation of renal calculi. Reflux and pyelonephritis would not lead to calculi as much as stasis would. Neither glomerulonephritis nor increased bladder compliance causes the stasis that would lead to calculus formation. REF: p. 748
Visual disturbances are a common occurrence in patients with untreated Graves disease. The endocrinologist explains to the patient that the main cause of these complications is: a. decreased blood flow to the eye. b. orbital edema and protrusion of the eyeball. c. TSH neurotoxicity to retinal cells. d. local lactic acidosis.
ANS: B Visual disturbances with Graves disease include orbital fat accumulation, inflammation, and edema of the orbital contents resulting in exophthalmos (protrusion of the eyeball), periorbital edema, and extraocular muscle weakness leading to diplopia (double vision). Blood flow to the eye is not an effect, but visual changes occur. Functional abilities of the eye result from hyperactivity of the sympathetic system. Lactic acid is not involved with visual changes in the eye. REF: p. 468
Which is a characteristic of idiopathic pulmonary arterial hypertension (IPAH)? (select all that apply) a. Male gender b. Fatigue c. Dyspnea d. Jugular vein distention e. Weight gain

Which of the following conditions should alert the nurse that the patient may have both types of valve dysfunctions? a. Heart failure b. Connective tissue disorders c. Rheumatic fever or heart disease d. Syphilis infection
ANS: C Valvular dysfunction is often related to rheumatic fever. Heart failure decreases cardiac output but does not affect valvular function. It is not due to connective tissue disorders. Syphilis infection could affect valves, but it is not the most common cause. REF: p. 625
What type of effect occurs when insulin binds to its receptors on muscle cells, resulting in an increase in glucose uptake by those muscle cells? a. Pharmacologic b. Permissive c. Biphasic d. Direct
ANS: D Direct effects are the obvious changes in cell function that result specifically from stimulation by a particular hormone as is true with insulin. Pharmacologic effects are the result of high doses of a drug. Permissive effects are less obvious hormone-induced changes that facilitate the maximal response or functioning of a cell. Biphasic effects are twofold effects. REF: p. 441
Which factor will help the nurse differentiate leukotrienes from histamine? a. Site of production b. Vascular effect c. Chemotactic ability d. Time of release

A 60-year-old female has survived a myocardial infarction. The nurse is providing care for impaired ventricular function because: a. there is a temporary alteration in electrolyte balance. b. there is too much stress on the heart. c. the cells become hypertrophic. d. the resulting ischemia leads to hypoxic injury and myocardial cell death.
ANS: D The patient has impaired ventricular functioning because a portion of the myocardium has died due to ischemia. Impaired ventricular function is due to damage to the myocardium; it is not due to electrolyte imbalance. There was stress on the heart, but the impaired functioning is due to myocardial damage secondary to ischemia. The impaired ventricular dysfunction is due to myocardial cell death, not hypertrophy. REF: p. 620
A 27-year-old male is admitted to a neurologic unit with a complete C-5 spinal cord transection. On initial assessment, he is bradycardic, hypotensive, and hyperventilating.

ANS: A An increase, not a decrease, in serum calcium inhibits parathyroid hormone (PTH) secretion. Thyroid-stimulating hormone would not affect PTH secretion. REF: p. 450
Muscle contractions occur when there is a decreased: a. distance between Z lines. b. A band length. c. Z line length. d. H zone distance.
ANS: A Anatomically, contraction occurs when the sarcomere shortens, so adjacent Z lines move closer together. Such a contraction does not occur in relationship to a decrease in A band or Z line length or a decrease in H zone distance. REF: p. 581
A patient has researched bradykinin on the Internet. Which information indicates the patient understands the functions of bradykinin? Bradykinin is involved in: a. increasing vascular permeability. b. vasoconstricting blood vessels. c. stimulating the clotting system. d. increasing degradation of prostaglandins.
ANS: A Bradykinin increases vascular permeability. It is not associated with vasoconstriction, stimulating the clotting system, or increasing degradation of prostaglandins. REF: p. 141
One difference between cardiac muscle and skeletal muscle is that: a. cardiac muscle cells are arranged in branching networks. b. skeletal muscle cells have only one nucleus. c. cardiac muscle cells appear striped. d. skeletal muscle cells contain sarcomeres.
ANS: A Cardiac cells are arranged in branching networks throughout the myocardium, whereas skeletal muscle cells tend to be arranged in parallel units throughout the length of the muscle. Cardiac muscle cells have only one nucleus, whereas skeletal muscle cells have many nuclei. Both cardiac and muscle cells appear striped and contain sarcomeres. REF: p. 578
A 10-year-old male is brought to the emergency room (ER) incoherent and semiconscious. CT scan reveals that he is suffering from cerebral edema. This type of edema is referred to as: a. localized edema. b. generalized edema. c. pitting edema. d. lymphedema.
ANS: A Cerebral edema is a form of localized edema. Generalized edema is manifested by a more uniform distribution of fluid in interstitial spaces. When pressure is applied, pitting edema results in an indention in the skin. Lymphedema is due to swelling in interstitial spaces, primarily in the extremities. REF: p. 116
As a result of a severe head injury, a patient is now experiencing respiratory abnormalities characterized by alternating periods of deep and shallow breathing with periods of apnea. What term should the nurse use when charting this condition? a. Cheyne-Stokes b. Frank-Starling c. Apnea d. Orthopnea
ANS: A Cheyne-Stokes respirations are characterized by alternating periods of deep and shallow breathing, with periods of apnea lasting from 15 to 60 seconds. Frank-Starling is related to the stretch of fibers. Apnea is cessation of respirations. Orthopnea is dyspnea that occurs when an individual lies flat. REF: p. 688
A 22-year-old presents with chronic bronchitis. Tests reveal closure of the airway during expiration. This condition is most likely caused by: a. thick mucus from hypertrophied glands. b. ventilation-perfusion mismatch. c. hyperventilation. d. thinning smooth muscle in the bronchioles.
ANS: A Chronic bronchitis is defined by hypersecretion of thick mucus. Ventilation-perfusion mismatch may occur, but chronic bronchitis is defined as hypersecretion of mucus. Neither hyperventilation nor thinning of smooth muscle occurs. REF: p. 701
A 65-year-old diagnosed with emphysema presents to the ER for difficulty breathing. Physical exam reveals both bluish skin and mucous membranes. What term will the nurse use to document these observations? a. Cyanosis b. Hemoptysis c. Hematemesis d. Ischemia
ANS: A Cyanosis is a blue color to the skin. Hemoptysis is the coughing up of blood or bloody secretions, and hematemesis is blood in the vomitus. Ischemia is a lack of blood supply to tissues. REF: p. 688
A patient presents reporting visual disturbances. When CT reveals a pituitary tumor and lab tests reveal elevated prolactin, the diagnosis of prolactinoma is made. Which intervention is the treatment of choice for this condition? a. Dopaminergic agonists b. Calcium c. Insulin d. Radiation
ANS: A Dopaminergic agonists (bromocriptine and cabergoline) are the treatment of choice for prolactinomas. Calcium is used to treat parathyroid disease. Insulin is used to treat diabetes. Radiation is not used to treat prolactionomas. REF: p. 466
Besides hyposecretion and hypersecretion, endocrine system dysfunction can result from: a. abnormal receptor activity. b. abnormal hormone levels. c. increased synthesis of second messengers. d. extracellular electrolyte alterations.
ANS: A Dysfunction may result from abnormal cell receptor function or from altered intracellular response to the hormone-receptor complex. Abnormal hormone levels can occur but are not the cause of endocrine dysfunction. Intracellular storage of second-messenger hormones would not lead to dysfunction; receptor function does. Extracellular electrolyte alterations may result from dysfunction, but they are not a cause. REF: p. 460
An infant develops a fever secondary to a bacterial infection. Which of the following most likely triggered the fever? a. Interleukin-1 b. Interleukin-6 c. Interleukin-10 d. Interferons (IFNs)
ANS: A Interleukin-1 is responsible for fever production. Interleukin-6 stimulates growth and differentiation of blood cells. Interleukin-10 helps decrease the immune response. INFs are members of a family of cytokines that protect against viral infections. REF: p. 143, Figure 6-6
How do lipid-soluble hormone receptors cross the plasma membrane? a. Diffusion b. Osmosis c. Active transport d. Endocytosis
ANS: A Lipid-soluble hormones cross by diffusion, not by osmosis, active transport, or endocytosis. REF: p. 443 | p. 444, Figure 18-6
A patient is admitted to the medical unit for complications of long-term, poorly controlled type 2 DM. Which of the following would the nurse expect to find in addition to elevated glucose? a. Atherosclerosis testbanks_and_xanax b. Metabolic alkalosis c. Elevated liver enzymes d. Anemia
ANS: A Macrovascular disease (lesions in large and medium-sized arteries) increases morbidity and mortality and increases risk for accelerated atherosclerosis. Acidosis, rather than alkalosis, would occur in this patient. Neither elevated liver enzymes nor anemia would be expected. REF: p. 480
A 56-year-old presents to his primary care provider for a checkup. Physical exam reveals edema, hepatomegaly, and muffled heart sounds. Which of the following is of greatest concern to the nurse? a. Tamponade b. Exudate c. Aneurysm d. Pulsus paradoxus
ANS: A Muffled heart sounds are an indication of tamponade, and with tamponade the blood backs up into the venous system, leading to hepatomegaly. Muffled heart sounds with hepatomegaly are symptoms of tamponade, not exudates. An aneurysm would present without symptoms. Pulsus paradoxus is manifested by a change in blood pressure during inspiration and expiration. REF: p. 623
A 54-year-old female is diagnosed with nephritic syndrome. Which of the following is a common symptom of this disease? a. Hematuria b. Dysuria c. Oliguria d. Proteinuria
ANS: A Nephritic syndrome is hematuria and red blood cell casts in the urine. Proteinuria is usually less severe than in nephrotic syndrome. The patient with nephritic syndrome does not experience dysuria or oliguria. REF: p. 759
Water movement between the ICF and ECF compartments is determined by: a. osmotic forces. b. plasma oncotic pressure. c. antidiuretic hormone. d. buffer systems.
ANS: A Osmotic forces determine water movement between the ECF and ICF compartments. Oncotic pressure pulls water at the end of the capillary, which makes it move between intra and extra as interstitial is considered extra. The antidiuretic hormone regulates water balance, which would make water move between the intra- and extracellular spaces. Buffer systems help regulate acid balance. REF: p. 115
A nurse is discussing the pressure generated at the end of diastole. Which term is the nurse describing? a. Preload b. Afterload c. Systemic vascular resistance d. Total peripheral resistance
ANS: A Preload, not afterload, is the volume and associated pressure generated in the ventricle at the end of diastole. Afterload is the resistance to ejection of blood from the left ventricle. Systemic vascular resistance is related to afterload. Total peripheral resistance increases afterload. REF: p. 581
A 25-year-old female has sexual relations with her boyfriend. Later she is told that the boyfriend is infected with Neisseria gonorrhoeae. Testing reveals that she does not have the disease. How is it possible that she did not contract the disease? a. Antibodies covered sites of attachment. b. She was vaccinated against it. c. Platelets provided protection. d. IgE was released
ANS: A Some bacteria, such as Neisseria gonorrhoeae that causes gonorrhea, must attach to specific sites on urogenital epithelial cells. Antibodies may protect the host by covering sites on the microorganism that are needed for attachment, thereby preventing infection. Neither a vaccination, the protection of platelets, nor the release of IgE was relevant to the client's ability to avoid contracting this disease. REF: pp. 162-163
A 51-year-old male is at the health clinic for an annual physical exam. After walking from the car to the clinic, he developed substernal pain. He also reported discomfort in his left shoulder and his jaw, lasting 2-3 minutes and then subsiding with rest. He indicates that this has occurred frequently over the past few months with similar exertion. The nurse suspects he is most likely experiencing: a. Stable angina b. Unstable angina c. Prinzmetal angina d. Myocardial infarction (MI)
ANS: A Stable angina is associated with activity and subsides with rest. Unstable angina is a form of acute coronary syndrome that results from reversible myocardial ischemia and occurs at rest. Chest pain that occurs at rest and at night is descriptive of Prinzmetal angina. MI pain does not subside with rest. REF: p. 614
The complement, clotting, and kinin systems share which of the following characteristics? a. Activation of a series of proenzymes b. Phagocytosis initiation c. Granulocyte production d. Activated by interferon
ANS: A The complement system, the clotting system, and the kinin system are normally in inactive forms but can activate in a series as proenzymes and are involved in the inflammatory process. This system is not associated with phagocytosis, granulocyte production, or the activation of interferon. REF: p. 138
A 57-year-old presents with cough, sputum production, dyspnea, and decreased lung volume and is diagnosed with pneumoconiosis. When taking the patient's history, which finding is the most probable cause of the illness? a. Inhalation of silica b. Autoimmune disease c. Allergic reactions d. Flail chest
ANS: A The dusts of silica, asbestos, and coal are the most common causes of pneumoconiosis. Pneumoconiosis is neither an autoimmune nor an allergic disorder; it is not due to flail chest. REF: p. 695
A 20-year-old male received a knife wound to the arm during an altercation. Which of the following types of immunity was compromised? a. Innate immunity b. Inflammatory response c. Adaptive immunity d. Specific immunity
ANS: A The epithelial cells of the skin are a part of innate immunity. The inflammatory response is not a type of immunity. Adaptive immunity is represented by the normal flora of the bowel. Specific immunity is a type of adaptive immunity and is not associated with a break in skin integrity. REF: pp. 134-135
For a patient with respiratory acidosis, chronic compensation by the body will include: a. kidney excretion of H+. b. kidney excretion of HCO3. c. prolonged exhalations to blow off CO2. d. protein buffering.
ANS: A The kidneys excrete H+ to compensate for respiratory acidosis. The kidneys do not excrete HCO3 to compensate; this would increase acidosis. Prolonged exhalations would not be effective for compensation, especially in a chronic state. Protein buffering is intracellular and would not be effective enough to compensate for respiratory acidosis. REF: pp. 128-130
While planning care for a patient with renal calculi, the nurse remembers the most important factor in renal calculus formation is: a. urine pH. b. body temperature. c. gender. d. serum mineral concentrations.
ANS: A The most important factor in renal calculus formation is urine pH, not gender, although calculi form more often in men. Neither body temperature nor serum mineral concentrations are as important as urine pH. REF: p. 749
The organism that causes tuberculosis is a: a. bacterium. b. fungus. c. virus. d. parasite.
ANS: A The organism that causes tuberculosis is a bacterium. Tuberculosis is not a fungus, a virus, or a parasite. REF: p. 706
A 42-year-old presents with dyspnea; rapid, shallow breathing; inspiratory crackles; decreased lung compliance; and hypoxemia.

What is the most likely diagnosis supported by the patient's condition? a. Acute respiratory distress syndrome (ARDS) b. Sarcoidosis c. Postoperative respiratory failure d. Malignant respiratory failure
ANS: A The patient is experiencing ARDS. The patient's symptoms do not support a diagnosis of sarcoidosis or either postoperative or malignant respiratory failure. REF: p. 696
If the patient has a problem with the pineal gland, which substance would the nurse monitor? a. Melatonin b. Epinephrine c. Cortisol d. Somatostatin
ANS: A The pineal glands secrete melatonin. The adrenal medulla secretes epinephrine. The adrenal cortex secretes cortisol. The thyroid gland secretes somatostatin. testbanks_and_xanax REF: p. 448
An 80-year-old develops pneumonia in the hospital. An assessment identifies that the patient is cyanotic and tachycardic and has developed a fever and a cough. Chest x-ray reveals pus in the pleural space. This symptomology supports which medical diagnosis? a. Empyema b. Emphysema c. Pleurisy d. Chyle
ANS: A The presence of pus in the pleural space is termed empyema; emphysema is a total lung disorder. Pleurisy causes pain with inspiration. Chyle is milky fluid with lymph and fat. REF: p. 692
A 55-year-old female presents to her primary care provider and reports dizziness, confusion, and tingling in the extremities. Blood tests reveal an elevated pH, decreased PCO2, and slightly decreased HCO3. Which of the following is the most likely diagnosis? a. Respiratory alkalosis with renal compensation b. Respiratory acidosis with renal compensation c. Metabolic alkalosis with respiratory compensation d. Metabolic acidosis with respiratory compensation
ANS: A With an elevated pH, the diagnosis must be alkalosis. Since the PCO2 is low, it is likely respiratory, with a slight decrease in HCO3 indicating renal compensation. REF: p. 130
A 29-year-old female presents with cloudy urine, flank pain, and hematuria. These signs and symptoms support which diagnosis? a. Acute cystitis b. Renal calculi c. Chronic renal failure d. Postrenal renal failure
ANS: A testbanks_and_xanax The patient is demonstrating symptoms of acute cystitis. Although renal calculi can cause pain and hematuria, they are not manifested by fever and cloudy urine. Chronic renal failure is not manifested by cloudy urine. Postrenal renal failure is not manifested by hematuria and cloudy urine. REF: p. 754
Direct effects of antibodies include: (select all that apply) a. neutralization. b. agglutination. c. precipitation. d. phagocytosis. e. division
ANS: A, B, C Directly, antibodies can affect infectious agents or their toxic products by neutralization (inactivating or blocking the binding of antigen to receptors), agglutination (clumping insoluble particles that are in suspension), or precipitation (making a soluble antigen into an insoluble precipitate). Indirectly, antibodies activate components of innate resistance, including complement and phagocytes. Antibodies are generally a mixed population of classes, specificities, and capacity to provide the functions listed above. REF: p. 162
Physical barriers that offer the body protection from damage and infection are located in the: (select all that apply) a. gastrointestinal tract. b. genitourinary tract. c. respiratory tract. d. lymph system. e. hematopoietic system.
ANS: A, B, C The physical barriers that cover the external parts of the human body offer considerable protection from damage and infection. These barriers are composed of tightly associated epithelial cells of the skin and of the linings of the gastrointestinal, genitourinary, and respiratory tracts. REF: p. 135
A nurse recalls acute orthostatic hypotension can be caused by: (select all that apply) a. prolonged immobility. b. drug action. c. starvation. d. volume depletion. e. exercise.
ANS: A, B, C, D Acute orthostatic hypotension occurs as a result of drug action, prolonged immobility, starvation, and volume depletion. Physical exhaustion, rather than exercise, could cause orthostatic hypotension. REF: p. 604
Blood flow is affected by: (select all that apply) a. blood viscosity. b. blood vessel diameter. c. blood pressure. d. blood vessel length. e. blood composition.
ANS: A, B, C, D Resistance to flow is generally greater in longer tubes because resistance increases with length but decreases with a wider diameter. Blood flow varies inversely with the viscosity of the fluid. Thick fluids move more slowly and experience greater resistance to flow than thin fluids. Increased blood pressure decreases blood flow because resistance is increased. Blood volume, not composition, plays a role in blood flow. REF: p. 587
Which assessment finding would be expected in pulmonary embolism (PE)? (select all that apply) a. Chest pain b. Tachycardia c. Tachypnea d. Fever e. Hemoptysis
ANS: A, B, C, D, E An individual with PE usually presents with the sudden onset of pleuritic chest pain, dyspnea, tachypnea, tachycardia, and unexplained anxiety. Occasionally syncope (fainting) or hemoptysis occurs. With large emboli, a pleural friction rub, pleural effusion, fever, and leukocytosis may be noted. Recurrent small emboli may not be detected until progressive incapacitation, precordial pain, anxiety, dyspnea, and right ventricular enlargement are exhibited. Massive occlusion causes severe pulmonary hypertension and shock. REF: p. 707
A nurse remembers that the primary actions of the complement cascade include: (select all that apply) a. increased vascular permeability. b. vasoconstriction. c. chemotaxis. d. opsonization. e. cell killing. f. increased clotting
ANS: A, C, D, E The actions of the complement cascade include increased vascular permeability and vasodilation, chemotaxis, opsonization, and cell killing. They do not involve vasoconstriction or increased clotting. REF: pp. 138-139
A nurse is evaluating stroke volume. Which of the following factors affect stroke volume? (select all that apply) a. Preload b. Peripheral vascular resistance c. Afterload d. Ejection fraction e. Contractility
ANS: A, C, E Preload, afterload, and contractility affect stroke volume. REF: p. 581
Mechanisms for defense against urinary pathogens in men include: (select all that apply) a. the long length of the urethra. b. the alkaline pH of urine. c. the secretion of mucus that traps bacteria. d. the antimicrobial secretions from the prostate. e. the implantation of the ureters in the bladder.
ANS: A, D Both the longer urethra and prostatic secretions decrease the risk of infection in men. The urine is not more alkaline, and they do not secrete mucus that traps bacteria. The ureters in men and women are implanted in similar positions and in their normal position; it is not a factor in the development of cystitis. REF: p. 753
A patient has a disease state that results from the secretion of toxins by bacteria. Which medical diagnosis will the nurse see documented on the chart? a. Malaria b. Tetanus c. Smallpox d. Hepatitis
ANS: B Some bacteria secrete toxins that harm individuals. For instance, specific bacterial toxins cause the symptoms of tetanus or diphtheria. This is not true of malaria, smallpox, or hepatitis. REF: p. 163
The most common cause of myocardial ischemia is: a. idiopathic vasospasm. b. arterial emboli from a heart valve. c. atherosclerosis. d. venous emboli.
ANS: C The most common cause of myocardial ischemia is atherosclerosis. Myocardial ischemia is not caused by idiopathic vasospams or venous emboli. Arterial emboli may cause ischemia, but atherosclerosis is the major cause of myocardial ischemia. REF: p. 610
A 35-year-old who was severely burned is now demonstrating symptomology associated with acute tubular necrosis (ATN). Which form of renal failure is this patient experiencing? a. Prerenal b. Intrarenal c. Extrarenal d. Postrenal
ANS: B Intrarenal acute kidney failure is associated with several systemic diseases but is commonly related to ATN. Prerenal renal failure occurs anterior to the kidney. Extrarenal renal failure occurs outside the kidney. Postrenal is due to diseases that obstruct the flow of urine from the kidneys. REF: p. 761
An experiment is designed to determine specific cell types involved in cell-mediated immune response. The experimenter is interested in finding cells that attack cells that have specific antigens. Which cells should be isolated? a. Lymphokine-producing cells b. T-cytotoxic cells c. Helper T cells d. Macrophages
ANS: B Cell-mediated immunity is driven by T-cytotoxic (Tc) cells that attack antigens directly and destroy cells that bear foreign antigens. Lymphokine-producing cells, helper T cells, and macrophages do not attack antigens directly and destroy cells that bear foreign antigens. REF: p. 159
A nurse is teaching the staff about antidiuretic hormone (ADH). Which information should the nurse include? Secretion of ADH is stimulated by: a. increased serum potassium. b. increased plasma osmolality. c. decreased renal blood flow. d. generalized edema.
ANS: B ADH is secreted when plasma osmolality increases or circulating blood volume decreases and blood pressure drops. ADH is not secreted by an increase in potassium, a decrease in renal blood flow, or the presence of generalized edema. REF: p. 118
Acute poststreptococcal glomerulonephritis is primarily caused by: a. swelling of mesangial cells in the Bowman space in response to the presence of bacteria. b. immune complex deposition in the glomerular capillaries and inflammatory damage. c. inflammatory factors that stimulate cellular proliferation of epithelial cells. d. accumulation of antiglomerular basement membrane antibodies.
ANS: B Acute poststreptococcal glomerulonephritis is caused by an antigen-antibody complex. Acute poststreptococcal glomerulonephritis is not due to swelling of the Bowman space. It is not an inflammatory process nor is it caused by an accumulation of antiglomerular basement membrane antibodies. REF: p. 758, Table 30-6
A 25-year-old male is diagnosed with a hormone-secreting tumor of the adrenal cortex. Which finding would the nurse expect to see in the lab results? a. Decreased blood volume b. Decreased blood K+ levels c. Increased urine Na+ levels d. Increased white blood cells
ANS: B Aldosterone is secreted from the adrenal cortex. It promotes renal sodium and water reabsorption and excretion of potassium, leading to decreased potassium levels. Blood volume actually increases with aldosterone secretion. Aldosterone promotes sodium reabsorption, leading to normal or decreased Na+ levels, and is not associated with white blood cells. REF: p. 117
A 15-year-old male who is allergic to peanuts eats a peanut butter cup. He then goes into anaphylactic shock. Which assessment findings will the nurse assess for? a. Bradycardia, decreased arterial pressure, and oliguria b. Bronchoconstriction, hives or edema, and hypotension c. Hypertension, anxiety, and tachycardia d. Fever, hypotension, and erythematous rash
ANS: B Anaphylactic shock is characterized by bronchoconstriction, hives, and hypotension; it does not involve oliguria, bradycardia, or hypotension. Septic shock, not anaphylactic shock, is manifested by fever and rash. REF: pp. 643-644
A 51-year-old male presents with recurrent chest pain on exertion and is diagnosed with angina pectoris. The pain occurs when: a. cardiac output has fallen below normal levels. b. the myocardial oxygen supply has fallen below demand. c. myocardial stretch has exceeded the upper limits. d. the vagus nerve is stimulated.
ANS: B Angina is chest pain caused by myocardial ischemia, which develops if the flow or oxygen content of coronary blood is insufficient to meet the metabolic demands of myocardial cells. A decrease in cardiac output would lead to general systemic symptoms, not just chest pain, which is due to a decrease in myocardial oxygenation. Myocardial stretch does not affect angina symptoms. When the vagus nerve is stimulated, a change in rate occurs; it does not precipitate chest pain. REF: p. 614
ADH release from the posterior pituitary is stimulated by which process? a. Low blood pressure sensed by baroreceptors in the kidneys. b. High plasma osmolarity sensed by osmoreceptors in the hypothalamus. c. Low osmolality sensed by osmoreceptors in the kidneys. d. High concentration of potassium sensed by chemoreceptors in the carotid body.
ANS: B As plasma osmolality increases, osmoreceptors are stimulated, the rate of ADH secretion increases, more water is reabsorbed from the kidney, and the plasma is diluted back to its set point osmolality. ADH release is stimulated by high serum osmolality, not lowered blood pressure, low osmolality, or high concentrations of potassium. REF: p. 448
What is the most common type of renal stone composed of? testbanks_and_xanax a. Struvite b. Cystine c. Calcium d. Uric acid
ANS: C The most common stone types are calcium oxalate or phosphate (70-80%). Struvite (magnesium-ammonium-phosphate) occurs 15% of the time. Cystine stoes are rare (less than 1%). Uric acid stones occur 7% of the time. REF: p. 748
Which of the following findings in the patient with Raynaud disease would indicate a need for further teaching? a. The patient eats bananas twice a day. b. The patient smokes cigarettes. c. The patient wears mittens outside. d. The patient takes calcium channel blockers.
ANS: B Cigarette smoking should be stopped to eliminate the vasoconstricting effects of nicotine. The bananas do not cause problems in this patient. The patient should wear mittens outside. Calcium channel blockers are an acceptable treatment for Raynaud disease. REF: p. 607
An 11-year-old is newly diagnosed with type 1 DM. Which classic symptoms should the nurse assess the patient for? a. Recurrent infections, visual changes, fatigue, and paresthesia b. Polydipsia, polyuria, polyphagia, and weight loss c. Vomiting, abdominal pain, sweet, fruity breath, dehydration, and Kussmaul breathing d. Weakness, vomiting, hypotension, and mental confusion
ANS: B Classic symptoms of type 1 DM include polydipsia, polyuria, polyphagia, and weight loss. Recurrent infections and visual changes are complications of diabetes. Vomiting, abdominal pain, and sweet breath are signs of diabetic ketoacidosis. Weakness, hypotension, and mental confusion are signs of hypoglycemia. REF: p. 473
Depolarization of a cardiac muscle cell occurs as the result of: a. a decrease in the permeability of the cell membrane to ions. b. the rapid movement of ions across the cell membrane. c. a blockade by calcium ions. d. stimuli instigated during the refractory period.
ANS: B Depolarization is caused by the movement of electrically charged solutes (ions) across cardiac cell membranes. Permeability must be increased for movement to occur. A blockage of calcium ions would decrease depolarization. No cardiac action potential can be initiated in the refractory period. REF: p. 576
A patient is admitted to the intensive care unit with a closed head injury sustained in a motorcycle accident. The injury has caused severe damage to the posterior pituitary. Which of the following complications should the nurse anticipate? a. Dilutional hyponatremia b. Dehydration from polyuria c. Cardiac arrest from hyperkalemia d. Metabolic acidosis
ANS: B Diabetes insipidus is a well-recognized complication of closed head injury and is manifested by polyuria leading to dehydration. The patient will experience hypernatremia, not hyponatremia. Electrolytes other than sodium are typically not affected with diabetes insipidus. Acidosis is not associated with diabetes insipidus. REF: p. 462
A 25-year-old female presents to her primary care provider reporting vaginal discharge of a white, viscous, and foul-smelling substance. She reports that she has been taking antibiotics for the past 6 months. Which finding will the nurse most likely see on the microorganism report? a. Clostridium difficile overgrowth b. Decreased Lactobacillus c. Streptococcus overgrowth d. Decreased Candida albicans
ANS: B Diminished colonization with Lactobacillus that occurs as a result of prolonged antibiotic treatment increases the risk for vaginal infections, such as vaginosis. Clostridium difficile and Candida albicans occur in the colon, not the vagina. Streptococcus overgrowth will occur in the mouth. REF: p. 136
A 10-year-old develops pneumonia. Physical exam reveals subcostal and intercostal retractions. The child reports that breathing is difficult with feelings that, "I cannot get enough air." What term should the nurse use to document this condition? a. Cyanosis b. Dyspnea c. Hyperpnea d. Orthopnea
ANS: B Dyspnea is defined as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity." Cyanosis is a bluish discoloration to the skin. Hyperpnea is an increased ventilatory rate and orthopnea is dyspnea that occurs when an individual lies flat. REF: p. 687
A 10-year-old male is diagnosed with a parasite. Which lab result should the nurse check for a response to the parasite? a. Monocytes b. Eosinophils c. Neutrophils d. Macrophages
ANS: B Eosinophils serve as the body's primary defense against parasites. Monocytes and neutrophils are phagocytic. Macrophages are not active against parasites; they act as long-term defense against infections. REF: p. 146
While planning care for a patient from general anesthesia, which principle should the nurse remember? A side effect of some general anesthetic agents is _____ diabetes insipidus. a. neurogenic b. nephrogenic c. psychogenic d. allogenic
ANS: B General anesthetics can lead to nephrogenic diabetes insipidus (DI). General anesthetics are not associated with any of the other forms of DI. testbanks_and_xanax REF: p. 462
What are the thickened areas of the sarcolemma of myocardial cells that enable electrical impulses to travel in a continuous cell-to-cell fashion called? a. Myosins b. Intercalated disks c. Troponin Ts d. I bands
ANS: B Intercalated disks allow electrical impulses to be transmitted rapidly from cardiac fiber to cardiac fiber because the network of fibers is connected at these disks. Myosins do not play a role in conduction. Troponin Ts are involved in contraction but are not part of the sarcolemma. I bands are a part of the filaments bud, which do not conduct impulses in a cell-to-cell fashion. REF: p. 578
A 30-year-old male was involved in a motor vehicle accident. The glass from the shattered window cut his face and neck. The scar, however, was raised and extended beyond the original boundaries of the wound. This pattern of scarring is caused by impaired: a. nutritional status. b. collagen synthesis. c. epithelialization. d. contraction.
ANS: B Impaired production of collagen can cause surface overhealing, leading to a keloid or a hypertrophic scar. Nutritional deficiencies would lead to healing problems, but not extended scarring. Necrosis or steroid use leads to impaired epithelialization. Impaired contraction would lead to drawing of tissues, not raised. REF: p. 153
Which of the following conditions would cause the nurse to monitor for hyperkalemia? a. Excess aldosterone b. Acute acidosis c. Insulin usage d. Metabolic alkalosis
ANS: B In acidosis, ECF hydrogen ions shift into the cells in exchange for ICF potassium and sodium; hyperkalemia and acidosis therefore often occur together. Acidosis does not cause excess aldosterone. Insulin would help treat hyperkalemia, not cause it. Alkalosis does not lead to hyperkalemia. REF: p. 124
A 42-year-old is diagnosed with constrictive pericarditis. The nurse assesses the blood pressure for decreased cardiac output because of: a. pericardial effusions. b. fibrosis and calcification of the pericardial layers. c. cardiomyopathy. d. hemorrhage in the pericardial cavity.
ANS: B In constrictive pericarditis, fibrous scarring compresses the heart and eventually reduces cardiac output. Pericardial effusion is manifested by chest pain. Cardiomyopathy is a general term for pathophysiological changes in the heart. Hemorrhage in the pericardial cavity will lead to tamponade. REF: pp. 623-624
Which assessment findings will the nurse observe in a patient diagnosed with severe pulmonary edema? a. Thick mucous secretions b. Pink, frothy sputum c. Hypocapnia d. Wheezing
ANS: B In severe edema, pink frothy sputum is expectorated, not thick mucous secretions. Neither hypocapnia nor wheezing is an expected assessment finding associated with pulmonary edema. REF: p. 695
A 49-year-old male presents reporting chest pain. EKG reveals ST elevation. He is diagnosed with myocardial ischemia. Which of the following interventions would be most beneficial? a. Administer a diuretic to decrease volume. b. Apply oxygen to increase myocardial oxygen supply. c. Encourage exercise to increase heart rate. d. Give an antibiotic to decrease infection.
ANS: B Increasing the myocardial oxygen supply is indicated to treat ischemia. A decrease in fluid volume is not appropriate. Heart rate should be decreased to decrease cardiac workload. Antibiotics are not the most beneficial; oxygen is. REF: pp. 615-616
A public health nurse is teaching the community about health promotion. Which information should the nurse include for innate immunity? Innate immunity is gained: a. following an illness. b. at birth. c. via injection of specific antibodies. d. in adulthood.

Increased rate, large tidal volumes, and no expiratory pause c. Rapid respirations with periods of apnea d. Very slow inhalations and rapid expirations
ANS: B Kussmaul respirations are characterized by a slightly increased ventilatory rate, very large tidal volumes, and no expiratory pause. Audible wheezing is usually associated with conditions such as asthma, and stridor indicates a narrowed airway. Cheyne-Stokes respirations are characterized by alternating periods of deep and shallow breathing, with periods of apnea lasting from 15 to 60 seconds. Kussmaul respirations do not have slow inhalations; bronchiolar disorders have these characteristics. REF: p. 688
Which of the following patients should the nurse assess for decreased oncotic pressure in the capillaries? A patient with: a. a high-protein diet. b. liver failure. c. low blood pressure. d. low blood glucose.
ANS: B Liver failure leads to lost or diminished plasma albumin production, and this contributes to decreased plasma oncotic pressure. A high-protein diet would provide albumin for the maintenance of oncotic pressure. Low blood pressure would lead to decreased hydrostatic pressure. Decreased glucose does not affect oncotic pressure. REF: p. 116
A patient was admitted to the intensive care unit with a diagnosis of acute myocardial infarction (MI) and is being treated for shock. The primary cause of shock is most likely: a. rapid heart rate. b. decreased cardiac contractility. c. increased capillary permeability. d. decreased afterload due to vasodilation.
ANS: B MI leads to decreased cardiac contractility due to a damaged myocardium and would lead to shock. A rapid heart rate would not cause shock. Increased capillary permeability would not lead to shock. Decreased afterload will not lead to shock associated with MI. REF: p. 637
The post-surgical patient is experiencing delayed wound healing. The dietitian believes the delay is related to nutritional intake. A deficiency in which of the following substances could directly affect healing? a. Vitamin D b. Ascorbic acid c. Melanin d. Cholesterol
ANS: B Most of the factors that interfere with the production of collagen in healing tissues are nutritional. Scurvy, for example, is caused by lack of ascorbic acid—one of the cofactors required for collagen formation by fibroblasts. The results of scurvy are poorly formed connective tissue and greatly impaired healing. Healing is not associated with vitamin D, melanin, or cholesterol. REF: p. 153
Neurogenic shock can be caused by any factor that inhibits the: a. parasympathetic nervous system. b. sympathetic nervous system. c. somatic nervous system. d. thalamus.
ANS: B Neurogenic shock is caused by any factor that inhibits the sympathetic nervous system or overstimulates the parasympathetic nervous system. Neurogenic shock is not caused by inhibition of the somatic system or of the thalamus. REF: pp. 642-643
The predominant phagocyte of early inflammation is the: a. eosinophil. b. neutrophil. c. lymphocyte. d. macrophage
ANS: B Neutrophils are the predominant phagocytes in the early inflammatory site, arriving within 6-12 hours after the initial injury. Eosinophils help limit and control inflammation, but they are not the prominent phagocyte. Lymphocytes are part of the innate immune response. Macrophages kill microorganisms. REF: p. 146
A 20-year-old male shoots his hand with a nail gun while replacing roofing shingles. Which of the following cell types would be the first to aid in killing bacteria to prevent infection in his hand? a. Eosinophils b. Neutrophils c. Leukotrienes d. Monocytes
ANS: B Neutrophils are the predominant phagocytes in the early inflammatory site, arriving within 6-12 hours after the initial injury. Eosinophils help limit and control inflammation. Leukotrienes are activators of the inflammatory response. Monocytes enter much later and replace leukocytes. REF: p. 146
A nurse takes an adult patient's blood pressure and determines it to be normal. What reading did the nurse obtain? a. Systolic pressure between 140 and 150 mm Hg b. Systolic pressure less than 120 mm Hg and diastolic pressure less than 80 mm Hg c. Systolic pressure less than 100 mm Hg regardless of diastolic pressure d. Systolic pressure greater than 140 mm Hg and a diastolic pressure of 100 mm Hg
ANS: B Normal blood pressure has a systolic pressure less than 120 mm Hg and diastolic pressure less than 80 mm Hg. A systolic pressure of 140 mm Hg or more would indicate stage I hypertension. A systolic pressure of less than 100 mm Hg would indicate low blood pressure. A diastolic pressure greater than 90 mm Hg would indicate hypertension. REF: p. 600, Table 24-1
A 20-year-old presents reporting difficulty breathing when lying down. What term should the nurse use to document this condition? a. Dyspnea b. Orthopnea c. Apnea d. Tachypnea
ANS: B Orthopnea is dyspnea that occurs when an individual lies flat. Dyspnea is shortness of breath that occurs with activity. Apnea is cessation of breathing, and tachypnea is rapid breathing. REF: p. 687
A 60-year-old undergoes surgery for a bone fracture. Which nursing measure would be most effective for preventing pulmonary embolism (PE) in this patient? a. Ensure that patient uses supplemental oxygen. b. Prevent deep vein thrombosis formation. c. Check hematocrit and hemoglobin levels frequently during the postoperative period. d. Promote aggressive fluid intake.
ANS: B PE most commonly results from embolization of a clot from deep venous thrombosis (DVT) involving the lower leg; thus, preventing these will help prevent pulmonary emboli. Oxygen will neither prevent emboli nor check hemoglobin and hematocrit. Fluid intake will help, but it is not as important as preventing DVT. REF: p. 706
A 73-year-old has increased pulmonary pressure resulting in right heart failure. A potential cause for the right heart to fail is: a. hypertension. b. left heart failure. c. acute pneumonia. d. pericarditis.
ANS: B Right-sided failure often follows left-sided failure when pulmonary congestion forces backward flow of blood into the left ventricle. It is not due to hypertension, pneumonia, or pericarditis. REF: p. 636
Superior vena cava syndrome (SVCS), causing venous distention in the upper extremities, is a result of progressive superior vena cava: a. inflammation. b. occlusion. c. distention. d. sclerosis.
ANS: B SVCS is a progressive occlusion of the SVC that leads to venous distention in the upper extremities and head. This distention is not a result of progressive inflammation, distention, or sclerosis. REF: p. 599
A 52-year-old male presents with pooling of blood in the veins of the lower extremities and edema. The diagnosis is chronic venous insufficiency, and an expected assessment finding of this disorder is: a. deep vein thrombus formation. b. skin hyperpigmentation. c. gangrene. d. edema above the knee.
ANS: B Symptoms include edema of the lower extremities and hyperpigmentation of the skin of the feet and ankles but deep vein thrombi do not form. Edema in these areas may extend to the knees but not above. Gangrene does not occur in veins but in arteries. REF: p. 598
What structure conducts action potentials down the atrioventricular septum? a. Bachmann bundle b. Bundle of His c. Sinoatrial node d. Atrioventricular node
ANS: B The bundle of His conducts action potentials down the atrioventricular septum, not the Bachmann bundle. The sinoatrial node conducts the potential along the atria while the atrioventricular node conducts impulses to the ventricles. REF: p. 576
Which of the following buffer pairs is considered the major plasma buffering system? a. Protein/fat b. Carbonic acid/bicarbonate c. Sodium/potassium d. Amylase/albumin
ANS: B The carbonic acid/bicarbonate buffer pair operates in both the lung and the kidney and is a major extracellular buffer. Protein and fat are nutrients not related to the buffering system. Sodium and potassium are electrolytes for fluid and electrolyte balance, not the major plasma buffering system for acid-base balance. Amylase is a carbohydrate enzyme, and albumin is a protein; neither is a buffering system. REF: p. 125
Which statement indicates teaching was successful regarding the classical pathway of the complement system? The classical pathway of the complement system is activated by: a. histamine. b. antigen-antibody complexes. c. leukotrienes. d. prostaglandins.
ANS: B The classical pathway of the complement system is activated by antibodies of the immune system, not by histamine, leukotrienes, or prostaglandins. REF: p. 139
What common neurologic disturbances should the nurse assess for in a patient with a pituitary adenoma? a. Coma b. Visual disturbances c. Confused states d. Breathing abnormalities
ANS: B The clinical manifestations of pituitary adenomas are visual changes including visual field impairments (often beginning in one eye and progressing to the other) and temporary blindness. Coma, confusion, and breathing abnormalities are not associated with pituitary adenomas. REF: p. 464
A 75-year-old male has severe chest pain and dials 911. Based upon the lab findings indicating a patient has elevated levels of cardiac troponins I and T, the nurse suspects which of the following has occurred? a. Raynaud disease b. Myocardial infarction (MI) c. Orthostatic hypotension d. Angina
ANS: B The diagnosis of acute MI is made on the basis of serial cardiac biomarker alterations. The cardiac troponins (troponins I and T) are the most specific indicators of MI. Elevated troponins I and T are indicative of MI, not Raynaud disease, orthostatic hypotension, or angina REF: p. 620
While planning care for elderly individuals, the nurse remembers the elderly are at a higher risk for developing dehydration because they have: a. a higher total body water volume. b. decreased muscle mass. c. increased thirst. d. an increased tendency toward developing edema.
ANS: B The elderly are at higher risk for dehydration due to a decrease in muscle mass. The elderly have a decrease in total body water and thirst. The increased tendency to develop edema is not related to dehydration. REF: p. 131, Geriatric Considerations
After teaching the staff about the clotting system, which statement indicates the teaching was successful? The end product of the clotting system is: a. plasmin. b. fibrin. c. collagen. d. factor X.
ANS: B The end product of the clotting system is fibrin. Plasmin activates the complement cascade. Collagen plays a factor in wound healing. Factor X is a first step in the clotting system. REF: p. 139
A 20-year history of smoking causes airways to be obstructed as a result of: a. excessive mucus production. b. loss of elastic recoil. c. infection and inflammation. d. airway edema.
ANS: B The major mechanism of airflow limitation is a loss of elastic recoil, not excessive mucus as with bronchitis. The major mechanism of airflow limitation in this situation is not associated with infection or airway edema. REF: p. 702
If a patient has a problem with the adrenal medulla, which of the following hormones should the nurse monitor? a. Cortisol b. Epinephrine c. Androgens d. Estrogens
ANS: B The major products stored and secreted by the adrenal medulla are the catecholamines epinephrine (adrenaline) and norepinephrine. The adrenal cortex secretes cortisol and androgens. The pituitary secretes estrogens. REF: p. 456, Figure 18-19
When a staff member asks the nurse which gland secretes ADH and oxytocin, how should the nurse respond? a. Anterior pituitary b. Posterior pituitary c. Hypothalamus d. Pineal
ANS: B The posterior pituitary secretes ADH, which is also called vasopressin, and oxytocin. The anterior pituitary secretes ACTH, melanocyte-stimulating hormone (MSH), somatotropic hormones (GH, prolactin), and glycoprotein hormones—follicle-stimulating hormone (FSH), LH, and TSH. The hypothalamus secretes PRF, which stimulates secretion of prolactin; PIF (dopamine), which inhibits prolactin secretion; TRH, which affects release of thyroid hormones; GH-releasing hormone (GHRH), which stimulates the release of GH; somatostatin, which inhibits the release of GH; gonadotropin-releasing hormone (GnRH), which facilitates the release of FSH and LH; corticotropin-releasing hormone (CRH), which facilitates the release of ACTH and endorphins; and substance P, which inhibits ACTH release and stimulates release of a variety of other hormones. The pineal gland secretes melatonin. REF: p. 448
A 75-year-old obese female presents to her primary care provider reporting edema in the lower extremities. Physical exam reveals that she has varicose veins. Upon performing the history, which of the following is a possible cause for the varicose veins? a. Extreme exercise b. Long periods of standing c. Trauma to the deep veins d. Ischemia
ANS: B The probable cause of the patient's varicose veins is gradual venous distention caused by the action of gravity on blood in the legs due to long periods of standing. Varicose veins are most likely due to long periods of standing leading to the action of gravity promoting venous distention. Exercise would help prevent this. Trauma can occur, but usually this affects the more superficial veins. Ischemia affects arteries not veins. REF: p. 598
During inflammation, the liver is stimulated to release plasma proteins, collectively known as: a. opsonins. b. acute phase reactants. c. antibodies. d. phagolysosomes.
ANS: B The synthesis of many plasma proteins by the liver is increased during inflammation. These proteins, which can be either proinflammatory or anti-inflammatory in nature, are referred to as acute phase reactants. Opsonins coat the surface of bacteria and increase their susceptibility to being phagocytized. Antibodies are proteins of the immune system. Phagolysosomes destroy bacteria. REF: p. 149
How are ions such as sodium and potassium transported in and out of the cell across the plasma membrane? A) Via the process of endocytosis and exocytosis B) Through small pores in the lipid bilayer C) By glycolipid carrier molecules D) Through leak and gated protein channels
D) Through leak and gated protein channels
A patient with one kidney underwent surgery for an adrenal tumor that removed a large portion of the zona glomerulosa. The nurse would expect a postsurgical decrease in the patient's: a. sodium. b. aldosterone. c. potassium. d. acid.
ANS: B The zona glomerulosa, the outer layer, constitutes about 15% of the cortex and primarily produces the mineralocorticoid aldosterone. The zona glomerulosa is not associated with sodium, potassium, or acid production. testbanks_and_xanax REF: p. 453
A 68-year-old male presents to the ER reporting chest pain. He has a history of stable angina that now appears to be unstable. He most likely has: a. mild to moderate atherosclerosis. b. impending myocardial infarction (MI). c. electrical conduction problems in the heart. d. decreased myocardial oxygen demand.
ANS: B Unstable angina is an indication of impending MI. Unstable angina could be caused by moderate atherosclerosis, altered electrical conduction, or a decrease in myocardial oxygen, but it is an indication of impending MI. REF: p. 616
Which physical feature supports the diagnosis of Cushing syndrome? a. Weight loss and muscle wasting b. Truncal obesity and moon face c. Pallor and swollen tongue d. Depigmented skin and eyelid lag
ANS: B Weight gain is the most common feature and results from the accumulation of adipose tissue in the trunk, facial, and cervical areas. These characteristic patterns of fat deposition have been described as "truncal obesity," "moon face," and "buffalo hump." Weight gain, not loss, is the most common feature of Cushing syndrome. Pallor is not associated with Cushing syndrome. The skin of the patient with Cushing syndrome is bronze in color. testbanks_and_xanax REF: p. 482
What phrase describes the condition in which a series of alveoli in the left lower lobe receive adequate ventilation but lack adequate perfusion? a. A right-to-left shunt b. Alveolar dead space c. A low ventilation-perfusion ratio d. Pulmonary hypotension
ANS: B When certain areas of the alveoli experience inadequate perfusion, it is referred to as dead space. The situation is not referred to as either a right-to-left shunt or as pulmonary hypotension. Shunting is due to a low ventilation-perfusion ratio. REF: p. 690
A 65-year-old male with a history of untreated hypertension is now experiencing left heart failure. A nurse recalls his untreated hypertension led to: a. ventricular dilation and wall thinning. b. myocardial hypertrophy and ventricular remodeling. c. inhibition of renin and aldosterone. d. alterations in alpha and beta receptor function.
ANS: B With hypertension comes increased afterload and resistance to ventricular emptying and more workload for the ventricle, which responds with hypertrophy of the myocardium and ventricular remodeling. Ventricular dilation can occur, but the wall will thicken, not thin. Renin and aldosterone release are increased, not inhibited. Alterations in alpha and beta functioning may occur, but the response to hypertension is myocardial hypertrophy and ventricular remodeling. REF: p. 632
While planning care for an elderly patient, the nurse remembers that increased age is associated with: (select all that apply) a. increased T-cell function. b. decreased immune function. c. increased production of antibodies. d. decreased numbers of circulating immune complexes. e. decreased ability to fight infection.
ANS: B, D, E Increased age is associated with diminished T-cell function, decreased immune function, diminished production of antibody responses, decreased circulating immune complexes, and decreased ability to fight infection. REF: p. 173, Geriatric Considerations
When a patient's CT scan reveals a lesion above the pontine micturition center, which condition would the nurse expect? a. Dyssynergia b. Detrusor hyperreflexia c. Detrusor areflexia d. Detrusor sphincter dyssynergia
ANS: B testbanks_and_xanax Neurologic disorders that develop above the pontine micturition center result in detrusor hyperreflexia, also known as an uninhibited or reflex bladder. Lesions that develop in upper motor neurons of the brain and spinal cord result in dyssynergia. Lesions that involve the sacral micturition center (below S1; may also be termed cauda equina syndrome) or peripheral nerve lesions result in detrusor areflexia (acontractile detrusor), a lower motor neuron disorder. Neurologic lesions that occur below the pontine micturition center but above the sacral micturition center (between C2 and S1) are also upper motor neuron lesions and result in detrusor hyperreflexia with vescico-sphincter dyssynergia. REF: p. 750
While planning care for a heart patient, which principle should the nurse recall? Right ventricular afterload is affected by: A. Vascular resistance in the systemic vessels B. Right end-diastolic pressure C. Pressures in the vena cava D. Pulmonary vascular resistance
D. Pulmonary vascular resistance
The nurse identified each of the following clinical manifestations of inflammation. Which would the nurse classify as a local response? (select all that apply) a. Fever b. Redness c. Swelling d. Heat e. Pain
ANS: B, C, D, E Local manifestations of inflammation are the result of the vascular changes associated with the inflammatory process, including vasodilation and increased capillary permeability. The symptoms include redness, heat, swelling, and pain. Fever is a symptom of infection. REF: p. 149
Biochemical secretions that trap and kill microorganisms include: a. hormones. b. neurotransmitters. c. earwax. d. gastric acid.
ANS: C Epithelial cells secrete several substances that protect against infection, including earwax. Hormones do not contain biochemical secretions that trap and kill microorganisms. Neurotransmitters carry important messages, and gastric acid helps break down food into its component parts, but neither contains biochemical secretions. REF: p. 135
How are ions such as sodium and potassium transported in and out of the cell across the plasma membrane? A) Via the process of endocytosis and exocytosis B) Through small pores in the lipid bilayer C) By glycolipid carrier molecules D) Through leak and gated protein channels
D) Through leak and gated protein channels
A 54-year-old male with a long history of smoking complains of excessive tiredness, shortness of breath, and overall ill feelings. Lab results reveal decreased pH, increased CO2, and normal bicarbonate ion. These findings help to confirm the diagnosis of: a. respiratory alkalosis. b. metabolic acidosis. c. respiratory acidosis. d. metabolic alkalosis.
ANS: C A decreased pH indicates acidosis. With increased CO2, it is respiratory acidosis. The bicarbonate is normal, so it cannot be metabolic acidosis. REF: pp. 128-129
What term should the nurse use to document a detached blood clot? a. Thrombus b. Embolus c. Thromboembolus d. Infarction
ANS: C A thrombus is a clot that remains attached to a vessel wall; a detached thrombus is a thromboembolus. An embolus is a bolus of material floating in the bloodstream. An infarction is death of tissue. REF: p. 599
A 26-year-old recently underwent surgery and is now experiencing dyspnea, cough, fever, and leukocytosis. Tests reveal a collapsed lung caused by the removal of air from obstructed alveoli. Which term is used to document this condition? a. Compression atelectasis b. Bronchiectasis c. Absorption atelectasis d. Hypoventilation
ANS: C Absorption atelectasis results from removal of air from obstructed or hypoventilated alveoli or from inhalation of concentrated oxygen or anesthetic agents. Compression atelectasis is caused by external pressure exerted by tumor, fluid, or air in the pleural space or by abdominal distention pressing on a portion of lung. Bronchiectasis is a dilation of the bronchi, not atelectasis. Hypoventilation is inadequate alveolar ventilation of the lungs; it is not due to removal of air. REF: p. 693
Warmth and redness of the skin are indicators of inflammation. Which of the following processes is responsible for this clinical manifestation? A) Increased vascular permeability B) Phagocytosis C) Vasoconstriction D) Vasodilation
D) Vasodilation
Which statement by the staff indicates teaching was successful concerning aldosterone? Secretion of aldosterone results in: a. decreased plasma osmolality. b. increased serum potassium levels. c. increased blood volume. d. localized edema.
ANS: C Aldosterone promotes renal sodium and water reabsorption and excretion of potassium, thus increasing blood volume. Aldosterone secretion would cause increased plasma osmolality but it does not promote the development of localized edema; it affects blood volume. REF: p. 117
What regulates aldosterone secretion? a. The sympathetic nervous system b. ACTH feedback c. The renin-angiotensin system d. Positive feedback
ANS: C Aldosterone synthesis and secretion are regulated primarily by the renin-angiotensin system. Aldosterone synthesis and secretion are not regulated by the sympathetic nervous system, adrenocorticotropic hormone feedback, or positive feedback. REF: p. 455

ANS: C Aortic regurgitation is manifested by widened pulse pressure resulting from increased stroke volume and diastolic backflow. Mitral regurgitation is manifested by heart failure. Mitral stenosis is manifested by pulmonary edema and heart failure. Aortic stenosis is manifested by narrowed pulse pressure. REF: p. 627
A 72-year-old has a history of hypertension and atherosclerosis. An echocardiogram reveals backflow of blood into the left ventricle. Which of the following is the most likely diagnosis documented on the chart? a. Mitral regurgitation b. Mitral stenosis c. Aortic regurgitation d. Aortic stenosis
ANS: C Aortic regurgitation would allow backward flow of blood into the left ventricle. Mitral regurgitation would allow backward flow of blood into the left atrium. Mitral stenosis would impede blood flow from the right atrium into the right ventricle. Aortic stenosis would impede blood flow into the aorta. REF: p. 627
A patient presents to a primary care provider reporting chest pain and is diagnosed with atherosclerosis. This disease is caused by: a. arterial wall thinning and weakening. b. abnormally dilated arteries and veins. c. abnormal thickening and hardening of vessel walls. d. autonomic nervous system imbalances.
ANS: C Atherosclerosis is a form of arteriosclerosis characterized by thickening and hardening of the vessel wall. Affected arteries are narrowed, not dilated. Atherosclerosis is not related to autonomic nervous system imbalances, which would lead to changes in rate or rhythm. REF: p. 607
In autocrine signaling: A) a cell releases a hormone. B) a cell signals a neighboring cell. C) a neuron signals another neuron. D) a cell signals itself.
D) a cell signals itself.
What is the cause of the hyperpigmentation seen in people with Cushing syndrome? a. Abnormal levels of cortisol b. Permissive effects of aldosterone when cortisol levels are altered c. Elevated levels of ACTH d. Hypersensitivity of melanocytes with sun exposure
ANS: C Bronze or brownish hyperpigmentation of the skin, mucous membranes, and hair occurs when there are very high levels of ACTH. The pigmentation changes associated with Cushing syndrome and Addison disease are not due to increased levels of cortisol or hypersensitivity of melanocytes. Aldosterone affects fluid balance. REF: p. 482
A 70-year-old female has brittle bones secondary to osteoporosis. Her primary care provider prescribes calcitonin to: a. activate vitamin D. b. stimulate osteoclastic activity. c. inhibit calcium resorption from bones. d. promote thyroid hormone release.

Foam cells in a fatty streak are: a. deposited adipose cells. b. injured neutrophils. c. macrophages that engulf low-density lipoprotein (LDL). d. lipid-laden mast cells.
ANS: C Foam cells are lipid-laden macrophages that engulf LDL. They are deposited in vessels, not adipose cells. Foam cells are not injured neutrophils nor are they mast cells. REF: p. 607 | p. 609
A 60-year-old female is diagnosed with hyperkalemia. Which assessment finding should the nurse expect to observe? a. Weak pulse b. Excessive thirst c. Oliguria d. Constipation
ANS: C Hyperkalemia is manifested by oliguria. Hypokalemia is manifested by a weak pulse; it is not caused by hyperkalemia. Hypokalemia is manifested by excessive thirst. Diarrhea, not constipation, is a manifestation of hyperkalemia. REF: p. 124, Table 5-6
Which symptom would the nurse expect in a patient diagnosed with hyperaldosteronism? a. Hypovolemia b. Hypotension c. Hypokalemia d. Hyponatremia
ANS: C Hypertension, hypokalemia, and neuromuscular manifestations are the hallmarks of primary hyperaldosteronism. Neither hypovolemia nor hyponatremia is associated with hyperaldosteronism. REF: p. 483
Bone fractures are a risk factor in chronic renal failure because: a. calcium is lost in the urine. b. osteoblast activity is excessive. c. the kidneys fail to activate vitamin D. d. autoantibodies to calcium molecules develop.
ANS: C Hypocalcemia is accelerated by impaired renal synthesis of 1,25 - dihydroxy-vitamin D3. The combined effect of vitamin D deficiency can result in renal osteodystrophies with increased risk for fractures. Calcium is not lost in the urine. Osteoblast activity is not accelerated. Antibodies do not develop. REF: pp. 765-766
A 45-year-old diagnosed with Graves disease underwent surgical removal of the thyroid gland. During the postoperative period, the patient's serum calcium is low. The most probable reason for her low serum calcium is: a. hyperparathyroidism secondary to Graves disease. b. myxedema secondary to surgery. c. hypoparathyroidism caused by surgical injury to the parathyroid glands. d. hypothyroidism resulting from lack of thyroid replacement.
ANS: C Hypoparathyroidism is most commonly caused by damage to the parathyroid glands during thyroid surgery, not secondary to Graves disease, myxedema, or the lack of thyroid replacement. REF: p. 470
A patient has done research on monoclonal antibodies on the Internet. Which statement indicates a correct understanding? Pure monoclonal antibodies are produced by: a. T lymphocytes. b. bone marrow. c. laboratories. d. fetuses.
ANS: C Monoclonal antibodies are produced in the laboratory from one B cell that has been cloned; thus, the entire antibody is of the same class, specificity, and function. Pure monoclonal antibodies are not produced by T lymphocytes, bone marrow, or fetuses. REF: p. 164, Box 7-1
A patient diagnosed with thyroid carcinoma would be expected to have T3 and T4 levels that are: a. high. b. low. c. normal. d. variable.
ANS: C Most individuals with thyroid carcinoma have normal T3 and T4 levels and are therefore euthyroid. REF: p. 470
Inflammatory cells have difficulty limiting the colonization of microorganisms in infective endocarditis because the: a. microorganisms are resistant. b. valves are avascular. c. microorganisms are sequestered in a fibrin clot. d. colonies overwhelm the phagocytes.
ANS: C In endocarditis, bacterial colonies are inaccessible to host defenses because they are embedded in the protective fibrin clots; it is not because the microorganisms are resistant, that the valves are avascular, or that the colonies overwhelm the phagocytes. REF: p. 630
When a person is in shock, a nurse remembers impairment in cellular metabolism is caused by: a. release of toxic substances. b. free radical formation. c. inadequate tissue perfusion. d. lack of nervous or endocrine stimulation.
ANS: C In shock, impaired cellular metabolism is caused by inadequate tissue perfusion. Impairment of cellular metabolism is the result of inadequate tissue perfusion; toxic substances could develop, but it would be secondary to the inadequate perfusion. Free radicals are not the cause of impaired cellular metabolism. The lack of nervous control would lead to vasodilation, but perfusion still occurs. REF: p. 637
A 70-year-old male with chronic renal failure presents with edema. Which of the following is the most likely cause of this condition? a. Increased capillary oncotic pressure. b. Decreased interstitial oncotic pressure. c. Increased capillary hydrostatic pressure. d. Increased interstitial hydrostatic pressure.
ANS: C Increased capillary hydrostatic pressure would facilitate increased movement from the capillary to the interstitial space, leading to edema. Increased capillary (plasma) oncotic pressure attracts water from the interstitial space back into the capillary. Decreased interstitial oncotic pressure would keep water in the capillary. Increased interstitial hydrostatic pressure would facilitate increased water movement from the interstitial space into the capillary. REF: pp. 115-116
Which nutrient would the nurse encourage the patient to consume for thyroid hormone synthesis? a. Zinc b. Sodium c. Iodine d. Calcium
ANS: C Iodine, not zinc, sodium, or calcium, is necessary for synthesis of thyroid hormone. REF: p. 450
Which organ system should the nurse monitor when the patient has long-term potassium deficits? a. Central nervous system (CNS) b. Lungs c. Kidneys d. Gastrointestinal tract
ANS: C Long-term potassium deficits lasting more than 1 month may damage renal tissue, with interstitial fibrosis and tubular atrophy. Long-term potassium deficits are not associated with damage to the CNS, GI tract, or lungs. REF: pp. 123-124
A macrophage was isolated and analyzed for major histocompatibility complex. Which of the following would be expected? a. MHC I only b. MHC II only c. MHC I and II d. Neither MHC I nor MHC II
ANS: C MHC I and II would be expected. REF: p. 168
The most common cause of primary hypothyroidism in adults is: A) bacterial infection of the thyroid gland. B) viral infection of the thyroid gland. C) congenital hypothyroidism. D) autoimmune thyroiditis.
D) autoimmune thyroiditis. Autoimmune thyroiditis (Hashimoto) is the most common cause of primary hypothyroidism in adults.
A 5-month-old child is admitted to the hospital with recurring respiratory infections. A possible cause of this condition is: a. hypergammaglobulinemia. b. increased maternal IgG. c. immune insufficiency. d. decreased maternal antibody breakdown, resulting in hyposensitivity.
ANS: C Normal human infants are immunologically immature when born, with deficiencies in antibody production, phagocytic activity, and complement activity, especially components of alternative pathways. They do not possess hypergammaglobulinemia. Possessing increased maternal IgG would not lead to recurring infections. The recurrent infections are due to decreased immunity, not maternal antibody breakdown. REF: p. 173, Pediatric Considerations
The patient generally acquires nosocomial pneumonia: a. at daycare centers. b. on airplanes. c. during hospitalization. d. in the winter season.
ANS: C Nosocomial infections are acquired in the hospital. Nosocomial infections are not associated with daycare centers or airplanes and may happen in any season. REF: p. 703
When an aide asks the nurse about the purpose of the inflammatory process, how should the nurse respond? a. To provide specific responses toward antigens. b. To lyse cell membranes of microorganisms. c. To prevent infection of the injured tissue. d. To create immunity against subsequent tissue injury.
ANS: C One purpose of the inflammatory process is to prevent infection and further damage by contaminating microorganisms. Specific response toward antigens is a part of the complement system that assists in the inflammatory response, but not its purpose. Lysis of cell membranes is part of the process of phagocytosis, which removes foreign material. Immunity cannot be achieved against future tissue injury. REF: p. 137
What is the earliest manifestation of diabetes-induced kidney dysfunction? a. Polyuria b. Glycosuria c. Microalbuminuria d. Decreased glomerular filtration
ANS: C Polyuria occurs due to increased fluid in the vascular space, and microalbuminuria is the earliest manifestation. While glycosuria occurs due to hyperglycemia, it is not the first sign of kidney dysfunction. Decreased glomerular filtration and polyuria can occur due to changes, but neither are initial manifestations. REF: p. 479
Which finding would support the diagnosis of respiratory acidosis? a. Vomiting b. Hyperventilation c. Pneumonia d. An increase in noncarbonic acids
ANS: C Respiratory acidosis occurs with hypoventilation, and pneumonia leads to hypoventilation. Vomiting leads to loss of acids and then to alkalosis. Hyperventilation leads to respiratory alkalosis. Metabolic acidosis is caused by an increase in noncarbonic acids. REF: pp. 128-129
A 10-year-old male presents with fever, lymphadenopathy, arthralgia, and nosebleeds. He is diagnosed with rheumatic heart disease. The most likely cause of this disease is: a. congenital heart defects. b. human immunodeficiency virus (HIV) infections. c. group A beta-hemolytic streptococcus infections. d. acute pericarditis.
ANS: C Rheumatic fever is a systemic, inflammatory disease caused by a delayed exaggerated immune response to infection by the group A beta-hemolytic streptococcus, not by congenital heart defects, HIV infections, or acute pericarditis. REF: pp. 628-629
A 50-year-old male with a 30-year history of smoking was diagnosed with bronchogenic cancer. He developed edema and venous distention in the upper extremities and face. Which of the following diagnosis will the nurse observe on the chart? a. Thromboembolism b. Deep vein thrombosis c. Superior vena cava syndrome (SVCS) d. Chronic venous insufficiency
ANS: C SVCS is a progressive occlusion of the superior vena cava that leads to venous distention in the upper extremities and head. Thromboembolism would not lead to the generalized symptoms described in the patient. Deep vein thrombosis would not lead to upper extremity symptoms. Chronic venous insufficiency would primarily affect one extremity. REF: p. 599
During shock states, glucose uptake is usually: a. enhanced. b. normal. c. impaired. d. energy intensive.
ANS: C Some compensatory mechanisms activated by shock contribute to decreased glucose uptake by the cells, not enhanced uptake, not normal uptake, and not energy-intensive uptake. REF: p. 637
A 13-year-old took a weight loss drug that activated the sympathetic nervous system. Which of the following assessment findings would the nurse expect? a. Decreased myocardial contraction b. Decreased heart rate c. Increased cardiac conduction d. Increased intranodal conduction time
ANS: C Stimulation of the SA node by the sympathetic nervous system rapidly increases cardiac conduction. Stimulation of the sympathetic nervous system would increase myocardial contraction and heart rate. Such simulation would not affect conduction time within the node. These are inherent rates. REF: p. 576
Where is the main site of aldosterone synthesis? a. Liver b. Kidneys c. Adrenal cortex d. Hypothalamus
ANS: C The adrenal cortex, not the liver, kidneys, or the hypothalamus, synthesizes aldosterone. REF: p. 453
Airway obstruction contributing to increased airflow resistance and hypoventilation in asthma is caused by: a. type II alveolar cell injury and decreased surfactant. b. alveolar fibrosis and pulmonary edema. c. mucous secretion, bronchoconstriction, and airway edema. d. collapse of the cartilaginous rings in the bronchi.
ANS: C The mediators of asthma cause vasodilation, increased capillary permeability, mucosal edema, bronchial smooth muscle contraction (bronchospasm), and mucous secretion from mucosal goblet cells with narrowing of the airways and obstruction to airflow. Acute respiratory distress syndrome involves type II injury. Alveolar fibrosis with pulmonary edema is not associated with asthma. Asthma is not associated with collapse of bronchiolar rings. REF: p. 698
A 5-year-old male is diagnosed with a bacterial infection. Cultures of the bacteria revealed lipopolysaccharides on the bacterial cell surface. Which of the complement pathways would be activated in this case? a. Classical pathway b. Lectin pathway c. Alternative pathway d. Kinin pathway
ANS: C The alternative pathway is activated by several substances found on the surface of infectious organisms, such as those containing lipopolysaccharides. The classical pathway is primarily activated by antibodies that are proteins of the acquired immune system. The lectin pathway is similar to the classical pathway but is independent of antibody. It is activated by several plasma proteins. The kinin pathway is involved in coagulation. REF: p. 139
A 55-year-old male died of a myocardial infarction. Autopsy would most likely reveal: a. embolization of plaque from the aorta. b. decreased ventricular diastolic filling time. c. platelet aggregation within the atherosclerotic coronary artery. d. smooth muscle dysplasia in the coronary artery.
ANS: C The autopsy would reveal platelet aggregation within an atherosclerotic coronary artery. The cause of death is most likely occlusion of the coronary artery, not emboli from the aorta, decreased filling time, or dysplasia in the artery. REF: p. 613
A patient with left heart failure starts to have a cough and dyspnea. Pulmonary symptoms common to left heart failure are a result of: a. inflammatory pulmonary edema. b. decreased cardiac output. c. pulmonary vascular congestion. d. bronchoconstriction.
ANS: C The clinical manifestations of left heart failure are the result of pulmonary vascular congestion and inadequate perfusion of the systemic circulation. Pulmonary edema does occur, but it is not due to inflammation. Decreased cardiac output does occur, but the pulmonary symptoms are related to pulmonary congestion. Pulmonary symptoms are not due to bronchoconstriction. REF: p. 633
A patient most prone to multiple organ dysfunction syndrome (MODS) is a patient with: a. myocardial infarction (MI). b. pulmonary disease. c. septic shock. d. autoimmune disease.
ANS: C The most common cause of MODS is septic shock, not MI, not pulmonary disease, and not autoimmune disease. REF: p. 644
Which of the following is responsible for initiating clonal selection? a. T cells b. B cells c. Antigens d. Lymphocytes
ANS: C The lymphocytes remain dormant until an antigen initiates clonal selection. T cells do not initiate clonal selection. B cells are antibodies. Lymphocytes are released into the circulation as immature cells that react with antigens. REF: p. 159
What is the most likely cause of chronic bronchitis in a 25-year-old? a. Chronic asthma b. Air pollution c. Cigarette smoke d. Recurrent pneumonias

Which is the most potent naturally occurring glucocorticoid? a. Aldosterone b. Testosterone c. Cortisol d. Prolactin
ANS: C The most potent naturally occurring glucocorticoid is cortisol, not aldosterone, testosterone, or prolactin. REF: p. 453
Local myogenic regulation of blood vessel diameter and thus blood flow through a vessel is an example of: a. autonomic regulation. b. somatic regulation. c. autoregulation. d. metabolic regulation.
ANS: C The myogenic hypothesis proposes that autoregulation originates in vascular smooth muscle, presumably of the arterioles, as a response to changes in arterial perfusion pressure. It is not a part of autonomic, somatic, or metabolic regulation. REF: p. 592
The pericardium is: a. the outer muscular layer of the heart. b. the innermost layer of the heart chambers. c. a membranous sac that encloses the heart. d. the heart's fibrous skeleton.
ANS: C The pericardium is the membranous sac that surrounds the heart. The outer layer that acts as the fibrous skeleton of the heart is the myocardium. The innermost layer of the heart is the endocardium. REF: p. 570
The molecule that aids in bonding of the troponin complex to actin and tropomyosin is troponin: a. C. b. I. c. T. d. M.
ANS: C Troponin T aids in the binding of the troponin complex to actin and tropomyosin. Troponin C contains binding sites for the calcium ions involved in contraction. Troponin I inhibits the ATPase of actomyosin. Troponin M is not a substance. REF: p. 580
The patient diagnosed with tuberculosis can transmit this disease through: a. skin contact. b. fecal-oral contact. c. airborne droplets. d. blood transfusions.
ANS: C Tuberculosis is transmitted through airborne droplets. Tuberculosis is not transmitted through skin contact, fecal-oral contact, or through a blood transfusion. REF: p. 706
A 65-year-old female is diagnosed with metastatic breast cancer. She has developed muscle wasting. Which of the following substances would be produced in large quantities to eliminate the tumor cells and cause muscle wasting? a. Interleukin-6 b. Eosinophils c. Tumor necrosis factor-alpha d. Platelets
ANS: C Tumor necrosis factor causes muscle wasting. Interleukin-6 stimulates growth and differentiation of blood cells. Eosinophils are stimulated by parasites. Platelets stimulate clotting. REF: p. 144
A 30-year-old male is demonstrating hematuria with red blood cell casts and proteinuria exceeding 3-5 grams per day, with albumin being the major protein. The most probable diagnosis the nurse will see documented on the chart is: a. cystitis. b. chronic pyelonephritis. c. acute glomerulonephritis. d. renal calculi.
ANS: C Two major symptoms distinctive of more severe glomerulonephritis are: (i) hematuria with red blood cell casts and (ii) proteinuria exceeding 3-5 grams per day with albumin (macroalbuminuria) as the major protein. Cystitis is not associated with proteinuria and so is not relevant to the diagnosis of glomerulonephritis. Chronic pyelonephritis is manifested by dysuria, not proteinuria. Proteinuria is not seen with renal calculi. REF: p. 755 | p. 757
A 25-year-old male presents to his primary care provider reporting changes in facial features. CT scan reveals a mass on the anterior pituitary, and lab tests reveal severely elevated growth hormone (GH). Which of the following would the nurse also expect to find? a. Decreased IGF-1 b. Hypotension c. Muscular atrophy d. Height increases
ANS: C With elevated levels of GH, there is resulting bony and soft tissue overgrowth; nerve entrapment occurs, leading to peripheral nerve damage manifested by weakness, muscular atrophy, foot drop, and sensory changes in the hands. IGF-1 increases, and there is an overgrowth of bone but not an increase in height or hypotension. REF: p. 465
Which valvular condition is characterized by the valve opening being constricted and narrowed, causing the valve leaflets, or cusps, to fail to open completely? a. Regurgitation b. Insufficiency c. Stenosis d. Incompetence
ANS: C Valvular stenosis occurs when the valve opening is constricted and narrowed. Valvular regurgitation occurs when blood moves backward into the chamber from which it came. Valvular insufficiency occurs when blood regurgitates backward into the chamber from which it came. Valvular incompetence leads to regurgitation. REF: p. 625
Which patient is most prone to metabolic alkalosis? A patient with: a. retention of metabolic acids. b. hypoaldosteronism. c. excessive loss of chloride (Cl). d. hyperventilation.
ANS: C When acid loss is caused by vomiting, renal compensation is not very effective because loss of Cl stimulates renal retention of bicarbonate, leading to alkalosis. Retention of metabolic acids would lead to acidosis, not alkalosis. Hypoaldosteronism leads to hyponatremia and does not cause alkalosis. Hyperventilation leads to respiratory alkalosis, not metabolic alkalosis. REF: p. 127
A nurse is caring for a patient diagnosed with SIADH. What severe complication should the nurse assess for? a. Stroke b. Diabetes insipidus c. Neurologic damage d. Renal failure
ANS: C When the hyponatremia of SIADH becomes severe, 110-115 milliequivalents per liter, confusion, lethargy, muscle twitching, convulsions, and severe and sometimes irreversible neurologic damage may occur. Neither stroke, diabetes insipidus, nor renal failure is associated with SIADH. REF: p. 462
A 42-year-old male is involved in a motor vehicle accident that has resulted in prerenal failure. What is the most likely cause of this patient's condition? a. Kidney stones b. Immune complex deposition in the glomerulus c. Inadequate renal blood flow d. Obstruction of the proximal tubule
ANS: C With blood loss, renal failure is due to inadequate blood flow since the trigger occurs outside of the kidney (prerenal). Kidney stones will lead to postrenal renal failure. Intrarenal renal failure is due to glomerular nephritis or obstruction of the proximal tubule. testbanks_and_xanax REF: p. 760
Which assessment finding would the nurse expect to be increased in a patient with deficient ADH production? a. Blood volume b. Urine osmolality c. Urine volume d. Arterial vasoconstriction
ANS: C With deficient ADH, the kidneys would not concentrate urine, leading to increased urine output. Blood volume would decrease with increased renal excretion of fluid. Urine osmolality would decrease. Arteries would dilate with deficient ADH production. testbanks_and_xanax REF: p. 448
A patient diagnosed with Addison disease reports weakness and is easily fatigued. What is the root of these symptoms? a. Hyperkalemia b. Hypoglycemia c. Hypocortisolism d. Metabolic acidosis
ANS: C With mild-to-moderate hypocortisolism, symptoms usually begin with weakness and easy fatigability. The weakness is not due to hyperkalemia, hypoglycemia, or metabolic acidosis. REF: p. 484
A patient diagnosed with Graves disease is admitted to a medical-surgical unit. Which of the following symptoms would the nurse expect to find before treatment? a. Weight gain, cold intolerance b. Slow heart rate, rash c. Skin hot and moist, rapid heart rate d. Constipation, confusion
ANS: C testbanks_and_xanax Symptoms of Graves disease include heat intolerance and increased tissue sensitivity to stimulation by the sympathetic division of the autonomic nervous system.

As a result of blockage in the pulmonary artery, blood would first back up into the: a. aorta. b. left ventricle. c. pulmonary veins. d. right ventricle.
ANS: D Blockage in the pulmonary artery would cause blood to back up into the right ventricle, not the aorta since these two vessels do not communicate. The pulmonary artery and left ventricle do not communicate. Blockage in the pulmonary artery would not cause blood to back up into the pulmonary vein since the pulmonary vein takes blood to the left atrium. REF: p. 571
A nurse is reviewing lab reports. The nurse recalls blood plasma is located in which of the following fluid compartments? a. Intracellular fluid (ICF) b. Extracellular fluid (ECF) c. Interstitial fluid d. Intravascular fluid

She also reports that her father has hypertension as well. A nurse determines which of the following risk factors is most likely associated with this diagnosis? a. Race b. Diet c. Age d. Genetic
ANS: D Genetic factors, such as family history of hypertension, are the number one factor in the development of hypertension. Race and diet may be factors, but genetic factors are primary. Age is a factor, but not in this case; since the patient is 30, genetics are a greater factor. REF: p. 600
The cardiac electrical impulse normally begins spontaneously in the sinoatrial (SA) node because it: a. has a superior location in the right atrium. b. is the only area of the heart capable of spontaneous depolarization. c. has rich sympathetic innervation via the vagus nerve. d. depolarizes more rapidly than other automatic cells of the heart.
ANS: D Cardiac impulses occur in the SA node because its cells depolarize more rapidly than other automatic cells, not because of its superior location. The SA node is not the only area of the heart capable of spontaneous depolarization. The SA node does have rich innervations but by parasympathetic innervation from the vagus nerve. REF: p. 576
When catecholamines are released in a patient, what should the nurse assess for? a. Nutrient absorption b. Fluid retention c. Hypotension d. Hyperglycemia
ANS: D Catecholamines cause hyperglycemia and immune suppression. Catecholamines do not cause nutrient absorption, fluid retention, or hypotension. REF: p. 456
A patient is diagnosed with coronary artery disease. Which of the following modifiable risk factors would the nurse suggest the patient change? a. Eating meat b. Living arrangements c. Drinking tomato juice d. Smoking cigarettes
ANS: D Cigarette smoking leads to vasoconstriction and should be the first behavior the patient changes. Eating meat alone would not lead to the development of coronary artery disease. The living arrangement of the patient's home would not lead to the development of coronary artery disease. Drinking tomato juice would not lead to the development of coronary artery disease. REF: p. 611| p. 612
A 44-year-old patient with pulmonary tuberculosis is evaluated for SIADH. Which assessment finding would support this diagnosis? a. Peripheral edema b. Tachycardia testbanks_and_xanax c. Low blood pressure d. Concentrated urine

A 75-year-old female has been critically ill with multiple organ dysfunction syndrome (MODS) for longer than a week and has developed a severe oxygen supply and demand imbalance. The statement that best describes this imbalance is which of the following? a. Increased oxygen delivery to cells fails to meet decreased oxygen demands. b. The amount of oxygen consumed by cells depends only on the needs of cells, because there is oxygen in reserve. c. The situation results in supply-independent consumption. d. The reserve has been exhausted, and the amount of oxygen consumed depends on the amount the circulation is able to deliver.
ANS: D In MODS, the reserve has been exhausted and the body cannot meet the oxygenation demands. It is true that oxygen fails to meet demand, but there is no increase in oxygen because reserves are exhausted. There is no oxygen in reserve. The situation is supply and demand, but the demand cannot be met. REF: p. 648
An experiment was designed to test the effects of the Starling forces on fluid movement. Which of the following alterations would result in fluid moving into the interstitial space? a. Increased capillary oncotic pressure. b. Increased interstitial hydrostatic pressure. c. Decreased capillary hydrostatic pressure. d. Increased interstitial oncotic pressure.
ANS: D Increased interstitial oncotic pressure would attract water from the capillary into the interstitial space. Increased capillary oncotic pressure would attract water from the interstitial space back into the capillary. Increased interstitial hydrostatic pressure would attract movement of water from the interstitial spaces into the capillary. Decreased capillary hydrostatic pressure would move water into the capillaries. REF: p. 115
A child fell off a swing and scraped his right knee. The injured area becomes painful. What else will the nurse observe upon assessment? a. Vasoconstriction at injured site b. Decreased RBC concentration at injured site c. Pale skin at injured site d. Edema at injured site

How do the releasing hormones that are made in the hypothalamus travel to the anterior pituitary? a. Vessels of the zona fasciculata b. Chromophils c. Median eminence d. Hypophyseal portal system
ANS: D Neurons in the hypothalamus secrete releasing hormones into veins that carry the releasing hormones directly to the vessels of the adenohypophysis via the hypophyseal portal system, thus bypassing the normal circulatory route. Zona fasciculata secretes abundant amounts of cortisol from the adrenal gland. Chromophils are the secretory cells of the adenohypophysis. The median eminence is part of the posterior pituitary, not the anterior. REF: p. 8
A nurse is preparing to teach on the subject of opsonins. Which information should the nurse include? Opsonins are molecules that: a. are composed of fatty acids. b. regulate inflammation. c. degranulate mast cells. d. enhance phagocytosis.

ANS: D Renal failure is associated with hyperkalemia and metabolic acidosis. Diabetes insipidus results in hypernatremia. Pulmonary disorders are a cause of respiratory acidosis or alkalosis but do not affect hyperkalemia. Cushing syndrome results in hypernatremia. REF: p. 124 | p. 127
A patient who has elevated thyroxine production should be assessed for which accompanying condition? a. Increased thyroid-releasing hormone (TRH) b. Increased anterior pituitary stimulation c. Decreased T4 d. Decreased thyroid-stimulating hormone (TSH)
ANS: D Secretion of TSH stimulates the synthesis and secretion of thyroid hormones. Increasing levels of T4 and T3 then feedback negatively on the pituitary and hypothalamus to inhibit TRH and TSH synthesis. With increased thyroxine production, TRH will be decreased. Increased thyroxine would lead to decreased anterior pituitary stimulation. Thyroxine is T4; its level will be elevated. REF: p. 440
A patient is diagnosed with renal calculus that is causing a urinary obstruction. Which symptoms would be most likely experienced? a. Anuria b. Hematuria c. Pyuria d. Flank pain

Her parents state that she has been sick with the "flu" for a week. Which of the following statements best explains her acidotic state? a. Increased insulin levels promote protein breakdown and ketone formation. b. Her uncontrolled diabetes has led to renal failure. c. Low serum insulin promotes lipid storage and a corresponding release of ketones. d. Insulin deficiency promotes lipid metabolism and ketone formation.
ANS: D testbanks_and_xanax With insulin deficiency, lipolysis is enhanced, and there is an increase in the amount of nonesterified fatty acids delivered to the liver. The consequence is increased glyconeogenesis contributing to hyperglycemia and production of ketone bodies (acetoacetate, hydroxybutyrate, and acetone) by the mitochondria of the liver at a rate that exceeds peripheral use. Insulin levels are decreased. There is no evidence that the patient is in renal failure. Insulin is low, but the ketones are the result of fatty acid breakdown due to lack of insulin, not because of lipid storage. REF: p. 477
