Test 4 Nurs 215

ANS: B The thyroid is usually nonpalpable. The nurse should simply document the finding. There is no need to notify the health care provider immediately about a normal finding. There is no indication for thyroid-stimulating hormone (TSH) testing unless there is evidence of thyroid dysfunction. Deep palpation of the neck is not appropriate

During the physical examination, the nurse cannot feel the patient's thyroid gland. What action should the nurse take? a. Palpate the patient's neck more deeply. b. Document that the thyroid was nonpalpable. c. Notify the health care provider immediately. d. Teach the patient about thyroid hormone testing

ANS: B Checking for flank pain is performed by percussion of the CVA and asking about pain. The other techniques would not assess for flank pain.

How will the nurse assess for flank tenderness in a patient with suspected pyelonephritis? a. Palpate along both sides of the lumbar vertebral column. b. Strike a flat hand covering the costovertebral angle (CVA). c. Push fingers upward into the two lowest intercostal spaces. d. Percuss between the iliac crest and ribs at the midaxillary line

ANS: C Physical and emotional stress can affect the results of the free cortisol test. Stress does not impact the other tests.

In preparation for which test should the nurse teach the patient to minimize physical and emotional stress? a. A water deprivation test b. A test for serum T3 and T4 levels c. A 24-hour urine test for free cortisol d. A radioactive iodine (I-131) uptake test

ANS: B The kidneys are protected by the abdominal organs, ribs, and muscles of the back and may not be palpable under normal circumstances. No action is needed except to document the assessment information.

The nurse completing a physical assessment for a newly admitted patient is unable to feel either kidney on palpation. Which action should the nurse take? a. Obtain a urine specimen to check for hematuria. b. Document the information on the assessment form. c. Ask the patient about any history of recent sore throat. d. Ask the health care provider about scheduling a renal ultrasound.

ANS: D When the patient is ketotic, exercise may result in an increase in blood glucose level. Patients with type 1 diabetes should be taught to avoid exercise when ketosis is present. The other statements are correct.

A 28-yr-old male patient with type 1 diabetes reports how he manages his exercise and glucose control. Which behavior indicates that the nurse should implement additional teaching? a. The patient always carries hard candies when engaging in exercise. b. The patient goes for a vigorous walk when his glucose is 200 mg/dL. c. The patient has a peanut butter sandwich before going for a bicycle ride. d. The patient increases daily exercise when ketones are present in the urine.

ANS: C Because many patients have some diabetic retinopathy when they are first diagnosed with type 2 diabetes, a dilated eye examination is recommended at the time of diagnosis and annually thereafter.

A 30-yr-old patient has a new diagnosis of type 2 diabetes. When should the nurse recommend the patient schedule a dilated eye examination? a. Every 2 years b. Every 6 months c. As soon as available d. At the age of 39 years

ANS: B The patient's age and diagnosis indicate a likelihood of nocturia, so leaving the light on in the bathroom is appropriate. Fluids should be encouraged because dehydration is more common in older patients. The information in the question does not indicate that measurement of the patient's output is necessary or that the patient has overflow incontinence.

A 78-yr-old patient has been admitted with benign prostatic hyperplasia. What is mostappropriate to include in the nursing plan of care? a. Limit fluid intake to no more than 1000 mL/day. b. Leave a light on in the bathroom during the night. c. Ask the patient to use a urinal so that urine can be measured. d. Pad the patient's bed to accommodate overflow incontinence

ANS: A Before planning any interventions, the nurse should complete the assessment and determine the patient's normal bladder pattern and the usual measures used by the patient at home. Other responses may be appropriate, but until the assessment is complete, an individualized plan for the patient cannot be developed.

A female patient being admitted with pneumonia has a history of neurogenic bladder due to a spinal cord injury. Which action will the nurse plan to take first? a. Ask about the usual urinary pattern and any measures used for bladder control. b. Assist the patient to the toilet at scheduled times to help ensure bladder emptying. c. Check the patient for urinary incontinence every 2 hours to maintain skin integrity. d. Use intermittent catheterization on a regular schedule to avoid the risk of infection

ANS: B This answer describes the technique for obtaining a clean-catch specimen. The answer beginning, "insert a short, small, 'mini' catheter attached to a collecting container" describes a technique that would result in a sterile specimen, but a health care provider's order for a catheterized specimen would be required. Using Betadine before obtaining the specimen might result in suppressing the growth of some bacteria. The technique described in the answer beginning "have the patient empty the bladder completely" would not result in a sterile specimen.

A female patient with a suspected urinary tract infection is to provide a clean-catch urine specimen for culture and sensitivity testing. What should the nurse do to obtain the specimen? a. Have the patient empty the bladder completely; then obtain the next urine specimen that the patient is able to void. b. Tell the patient to clean the urethral area, void a small amount into the toilet, then void directly into a sterile container. c. Insert a short sterile "mini" catheter attached to a collecting container into the urethra and bladder to obtain the specimen. d. Clean the area around the patient's meatus with a povidone iodine (Betadine) swab and then have the patient void into a sterile specimen cup.

ANS: B The decrease in renal function may indicate a need to adjust the dose of metformin or change to a different medication. In older patients, the goal for A1C may be higher in order to avoid complications associated with hypoglycemia. The nurse will plan on scheduling the patient for an eye examination and addressing the questions about diet, but the area for prompt intervention is the patient's decreased renal function.

A few weeks after an 82-yr-old patient with a new diagnosis of type 2 diabetes has been placed on metformin (Glucophage) therapy, the home health nurse makes a visit. Which finding should the nurse promptly discuss with the health care provider? a. Hemoglobin A1C level is 7.9%. b. Glomerular filtration rate is decreased. c. Last eye examination was 18 months ago. d. Patient has questions about the prescribed diet.

ANS: B The decrease in renal function may indicate a need to adjust the dose of metformin or change to a different medication. In older patients, the goal for A1C may be higher in order to avoid complications associated with hypoglycemia. The nurse will plan on scheduling the patient for an eye examination and addressing the questions about diet, but the area for prompt intervention is the patient's decreased renal function.

A few weeks after an 82-yr-old patient with a new diagnosis of type 2 diabetes has been placed on metformin (Glucophage) therapy, the home health nurse makes a visit. Which finding should the nurse promptly discuss with the health care provider? a. Hemoglobin A1C level is 7.9%. b. Glomerular filtration rate is decreased. c. Last eye examination was 18 months ago. d. Patient has questions about the prescribed diet.

ANS: D Because creatinine clearance testing involves a 24-hour urine specimen, the nurse should obtain a large container for the urine collection. Catheterization, cleaning of the perineum with antiseptic towelettes, and a sterile specimen cup are not needed for this test.

A hospitalized patient who has possible renal insufficiency after coronary artery bypass surgery will have a creatinine clearance test. Which item will the nurse need to obtain? a. Urinary catheter b. Sterile specimen cup c. Cleansing towelettes d. Large urine container

ANS: C A red-orange color in the urine is normal with some over-the-counter (OTC) medications such as phenazopyridine. The color is not expected with urinary tract infection, is not a sign that poor technique was used in obtaining the specimen and does not need to be communicated to the health care provider until further assessment is done.

A male patient in the clinic provides a urine sample that is red-orange in color. Which action should the nurse take? a. Notify the patient's health care provider. b. Teach correct midstream urine collection. c. Ask the patient about current medications. d. Question the patient about urinary tract infection risk factors.

ANS: D Parathyroid hormone (PTH) is the major controller of blood calcium levels. Although calcitonin secretion is a counter mechanism to PTH, it does not play a major role in calcium balance. Catecholamine and thyroid hormone levels do not affect serum calcium level.

A patient admitted with pneumonia has a total serum calcium level of 13.3 mg/dL. What should the nurse anticipate will be tested next? a. Calcitonin b. Catecholamine c. Thyroid hormone d. Parathyroid hormone

ANS: B Iodine-based contrast dye is used during IVP and for many CT scans. The nurse will need to notify the health care provider before the procedures so that the patient can receive medications such as antihistamines or corticosteroids before the procedures are started. The other information does not have immediate implications for the patient's care during the procedures.

A patient gives the admitting nurse health information before a scheduled intravenous pyelogram (IVP). Which item requires the nurse to intervene before the procedure? a. The patient has not had food or drink for 8 hours. b. The patient lists allergies to shellfish and penicillin. c. The patient reports costovertebral angle (CVA) tenderness. d. The patient used a bisacodyl (Dulcolax) tablet the previous night.

ANS: A Patients with most permanent pacemakers cannot have an MRI because of the force exerted by the magnetic field on metal objects. Supplemental oxygen can be delivered during the MRI. The patient will need to be instructed to remove the hearing aid before the MRI, but this does not require consultation with the health care provider. Because contrast medium will not be used, shellfish allergy is not a contraindication to MRI.

A patient has a new order for magnetic resonance imaging (MRI) to evaluate possible left femur osteomyelitis after hip arthroplasty surgery. Which information indicates the nurse should consult with the health care provider before scheduling the MRI? a. The patient has a pacemaker. b. The patient wears a hearing aid. c. The patient is allergic to shellfish. d. The patient uses supplemental oxygen

ANS: B When dealing with a patient with a chronic condition such as diabetes, identification of the patient's values and beliefs can assist the interprofessional team in choosing strategies for successful lifestyle change. The other information also will be useful but is not as important in developing an individualized plan for the necessary lifestyle changes.

A patient has been newly diagnosed with type 2 diabetes. Which information about the patient will be most useful to the nurse who is helping the patient develop strategies for successful adaptation to this disease? a. Ideal weight b. Value system c. Activity level d. Visual changes

ANS: C Tetany is associated with hypocalcemia. The other values would not be useful for this patient

A patient is admitted with tetany. Which laboratory value should the nurse plan to monitor? a. Total protein b. Blood glucose c. Ionized calcium d. Serum phosphate

ANS: C Cortisol levels are usually drawn in the morning, when levels are highest. The other instructions would be given to patients who were having other endocrine testing.

A patient is scheduled in the outpatient clinic for blood cortisol testing. Which instruction should the nurse provide? a. "Avoid adding any salt to your foods for 24 hours before the test." b. "You will need to lie down for 30 minutes before the blood is drawn." c. "Come to the laboratory to have the blood drawn early in the morning." d. "Do not have anything to eat or drink before the blood test is obtained."

ANS: C Because aldosterone increases the excretion of potassium, a medication that blocks aldosterone will tend to cause hyperkalemia. Aldosterone also promotes the reabsorption of sodium and water in the renal tubules, so spironolactone will tend to cause increased urine output, a decreased or normal serum sodium level, and signs of dehydration.

A patient is taking spironolactone (Aldactone), a drug that blocks the action of aldosterone on the kidney, for hypertension. What additional effect of the medication should the nurse monitor? a. Increased serum sodium b. Decreased urinary output c. Elevated serum potassium d. Evidence of fluid overload

ANS: C In a cystoscope and cystogram procedure, a cystoscope is inserted into the bladder for direct visualization, and then contrast solution is injected through the scope so that x-rays can be taken. The response beginning, "Your doctor will place a catheter" describes a renal arteriogram procedure. The response beginning, "Your doctor will inject a radioactive solution" describes a nuclear scan. The response beginning, "Your doctor will insert a lighted tube into the bladder, and little catheters will be inserted" describes a retrograde pyelogram.

A patient passing bloody urine has scheduled a cystoscopy with cystogram. Which description of the procedure by the nurse is accurate? a. "Your doctor will place a catheter into an artery in your groin and inject a dye to visualize the blood supply to the kidneys." b. "Your doctor will insert a lighted tube into the bladder, and little catheters will be inserted through the tube into your kidneys." c. "Your doctor will insert a lighted tube in the bladder through your urethra, inspect the bladder, and instill dye to outline your bladder on x-ray." d. "Your doctor will inject a radioactive solution into a vein in your arm, then the isotope in your kidneys and bladder will be visible on a scanner."

ANS: B The patient's pain will make it more difficult to accomplish tasks such as putting on a shirt or jacket. This pain should not affect the patient's ability to feed himself or use the toilet because these tasks do not involve moving the arm behind the patient. The arm will not usually be positioned behind the patient during sleeping.

A patient reports shoulder pain when the nurse moves the patient's arm behind the back. Which question should the nurse ask? a. "Are you able to feed yourself without difficulty?" b. "Do you have difficulty when you are putting on a shirt?" c. "Are you able to sleep through the night without waking?" d. "Do you ever have trouble lowering yourself to the toilet?"

ANS: C The patient's impaired fasting glucose indicates prediabetes, and the patient should be counseled about lifestyle changes to prevent the development of type 2 diabetes. The patient with prediabetes does not require insulin or oral hypoglycemics for glucose control and does not need to self-monitor blood glucose.

A patient screened for diabetes at a clinic has a fasting plasma glucose level of 120 mg/dL (6.7 mmol/L). What should the nurse plan to teach the patient? a. Self-monitoring of blood glucose b. Using low doses of regular insulin c. Lifestyle changes to lower blood glucose d. Effects of oral hypoglycemic medications

ANS: B Elevated levels of antidiuretic hormone will cause water retention and decrease serum sodium levels. The other tests would not be helpful in determining the cause of the patient's hyponatremia.

A patient seen in the emergency department for severe headache and acute confusion has a serum sodium level of 118 mEq/L. The nurse should anticipate the need for which diagnostic test? a. Urinary 17-ketosteroids b. Antidiuretic hormone level c. Growth hormone stimulation test d. Adrenocorticotropic hormone level

ANS: A High-phosphate enemas, such as Fleet enemas, should be avoided in patients with elevated BUN and creatinine because phosphate cannot be excreted by patients with renal failure. The other medications for bowel evacuation are more appropriate

A patient who has increased blood urea nitrogen (BUN) and serum creatinine levels is scheduled for a renal arteriogram. Which bowel preparation order would the nurse question for this patient? a. Fleet enema b. Tap-water enema c. Senna/docusate (Senokot-S) d. Bisacodyl (Dulcolax) tablets

ANS: B Because the usual contrast media is iodine-based, the health care provider will need to know about the allergy before the CT scan. The other findings are common with any mass in the brain such as a pituitary adenoma.

A patient with a possible pituitary adenoma is scheduled for a computed tomography (CT) scan with contrast media. Which patient information is important for the nurse to communicate to the health care provider before the test? a. Bilateral poor peripheral vision b. Allergies to iodine and shellfish c. Recent weight loss of 20 pounds d. Patient reports ongoing headaches

ANS: A Bursae are fluid-filled sacs that cushion joints and bony prominences. Fibrocartilage is a solid tissue that cushions some joints. Ligaments are connective tissue joining bones within a joint. The synovial membrane lines many joints but is not affected in bursitis

A patient with left knee pain is diagnosed with bursitis. What area should the nurse explain is the site of inflammation in bursitis? a. A fluid-filled sac found at some joints. b. A synovial membrane that lines some joints. c. The connective tissue joining bones within a joint. d. The fibrocartilage that acts as a shock absorber in the knee.

ANS: A DXA testing is painless and noninvasive. No IV access is necessary. Contrast medium is not used. Shellfish or iodine allergies are not a concern with DXA testing. Because the procedure is painless, antianxiety medications are not typically required

A patient with severe kyphosis is scheduled for dual-energy x-ray absorptiometry (DXA) testing. Which action should the nurse plan to take? a. Explain the procedure to the patient. b. Start an IV line for contrast injection. c. Give an oral sedative 60 to 90 minutes before the procedure. d. Screen the patient for allergies to shellfish or iodine products.

ANS: B Palpation can cause the release of thyroid hormones in a patient with an enlarged thyroid and should be avoided. The other actions by the new RN are appropriate when caring for a patient with an enlarged thyroid.

A registered nurse (RN) is caring for a patient with a goiter and possible hyperthyroidism. Which action by the RN indicates that the charge nurse needs to provide the RN with additional teaching? a. The RN checks the blood pressure in both arms. b. The RN palpates the neck to assess thyroid size. c. The RN orders saline eyedrops to lubricate the patient's bulging eyes. d. The RN lowers the thermostat to decrease the temperature in the room

ANS: D Exposure to the chemicals involved with working as a hair stylist and in smoking both increase the risk of bladder cancer, and the nurse should assess whether the patient understands this risk. The patient is not at increased risk for renal failure, pyelonephritis, or kidney stones.

A young adult employed as a hair stylist who has a 15 pack-year history of cigarette smoking arrives for an annual physical examination. Which area of increased risk should the nurse plan to teach the patient? a. Renal failure b. Kidney stones c. Pyelonephritis d. Bladder cancer

ANS: A Increased secretion of adrenocorticotropic hormone (ACTH) by the anterior pituitary gland will lead to an increase in serum and urinary cortisol levels. An increase, rather than a decrease, in thyroxine level would be expected with increased secretion of thyroid-stimulating hormone (TSH) by the anterior pituitary. The anterior pituitary does not control aldosterone and catecholamine levels.

A young adult patient who is being seen in the clinic has excessive secretion of the anterior pituitary hormones. Which laboratory test result should the nurse expect? a. Increased urinary cortisol b. Decreased serum thyroxine c. Elevated serum aldosterone d. Low urinary catecholamines

ANS: B Because the brain requires glucose to function, untreated hypoglycemia can cause unconsciousness, seizures, and death. The nurse will rapidly assess and treat the patient with low blood glucose. The other patients also have symptoms that require assessments or interventions, but they are not at immediate risk for life-threatening complications.

After change-of-shift report, which patient should the nurse assess first? a. A 19-yr-old patient with type 1 diabetes who has a hemoglobin A1C of 12% b. A 23-yr-old patient with type 1 diabetes who has a blood glucose of 40 mg/dL c. A 50-yr-old patient who uses exenatide (Byetta) and is reporting acute abdominal pain d. A 40-yr-old patient who is pregnant and whose oral glucose tolerance test is 202 mg/dL

ANS: B Because the brain requires glucose to function, untreated hypoglycemia can causeunconsciousness, seizures, and death. The nurse will rapidly assess and treat the patient with low blood glucose. The other patients also have symptoms that require assessments or interventions, but they are not at immediate risk for life-threatening complications.

After change-of-shift report, which patient should the nurse assess first? a. A 19-yr-old patient with type 1 diabetes who has a hemoglobin A1C of 12% b. A 23-yr-old patient with type 1 diabetes who has a blood glucose of 40 mg/dL c. A 50-yr-old patient who uses exenatide (Byetta) and is reporting acute abdominal pain d. A 40-yr-old patient who is pregnant and whose oral glucose tolerance test is 202 mg/dL

ANS: D The patient's diagnosis of HHS and signs of dehydration indicate that the nurse should rapidly assess for signs of shock and determine whether increased fluid infusion is needed. The other patients also need assessment and intervention but do not have life-threatening complications.

After change-of-shift report, which patient will the nurse assess first? a. A 19-yr-old patient with type 1 diabetes who was admitted with dawn phenomenon b. A 35-yr-old patient with type 1 diabetes whose most recent blood glucose reading was 230 mg/dL c. A 68-yr-old patient with type 2 diabetes who has severe peripheral neuropathy and reports burning foot pain d. A 60-yr-old patient with hyperosmolar hyperglycemic syndrome who has poor skin turgor and dry oral mucosa

ANS: D The patient's diagnosis of HHS and signs of dehydration indicate that the nurse should rapidly assess for signs of shock and determine whether increased fluid infusion is needed. The other patients also need assessment and intervention but do not have life-threatening complications

After change-of-shift report, which patient will the nurse assess first? a. A 19-yr-old patient with type 1 diabetes who was admitted with dawn phenomenon b. A 35-yr-old patient with type 1 diabetes whose most recent blood glucose reading was 230 mg/dL c. A 68-yr-old patient with type 2 diabetes who has severe peripheral neuropathy and reports burning foot pain d. A 60-yr-old patient with hyperosmolar hyperglycemic syndrome who has poor skin turgor and dry oral mucosa

ANS: C The usual technique in the physical assessment is to begin with inspection. Abnormalities in muscle mass or configuration will allow the nurse to perform a more focused assessment of affected areas. The other assessments are included but are usually done after inspection.

After completing the health history, how should the nurse begin to assess the musculoskeletal system? a. Feel for the presence of crepitus during joint movement. b. Have the patient move the extremities against resistance. c. Observe the patient's body build and muscle configuration. d. Check active and passive range of motion for the extremities

ANS: D Hypoglycemia is induced during the growth hormone stimulation test, and the nurse should be ready to administer 50% dextrose immediately. Regular insulin is used to induce hypoglycemia. The patient does not need cardiac monitoring during the test. Although blood samples for some tests must be kept on ice, this is not true for the growth hormone stimulation test.

An 18-yr-old male patient with small stature is scheduled for a growth hormone stimulation test. What should the nurse obtain in preparation for the test? a. Ice in a basin b. Glargine insulin c. A cardiac monitor d. 50% dextrose solution

ANS: C To decrease the incidence of macrovascular and microvascular problems in patients with diabetes, the blood pressure should be kept in normal range. An A1C less than 6.5%, a low resting heart rate (consistent with regular aerobic exercise in a young adult), and an HDL level of 65 mg/dL all indicate that the patient's diabetes and risk factors for vascular disease are well controlled.

An active 32-yr-old male who has type 1 diabetes is being seen in the endocrine clinic. Which finding indicates a need for the nurse to discuss a possible a change in therapy with the health care provider? a. Hemoglobin A1C level of 6.2% b. Heart rate at rest of 58 beats/min c. Blood pressure of 140/88 mmHg d. High-density lipoprotein (HDL) level of 65 mg/dL

ANS: D The nurse in the photo is using indirect percussion to determine the presence or absence of costovertebral angle (CVA) tenderness, which suggests pyelonephritis or polycystic kidney disease. The liver size would be percussed from the anterior direction with the patient positioned supine. Chest stability and excursion are determined by palpating and observing for symmetry of expansion. Pulmonary tissue density would be determined by tapping the interphalangeal joint over the lung fields and listening for resonance

In the accompanying figure, what is the nurse assessing via percussion? a. Liver size and shape b. Pulmonary tissue density c. Posterior chest skeletal stability d. Upper urinary tract inflammation

ANS:A, D, E, B, C When mixing regular insulin with NPH, it is important to avoid contact between the regular insulin and the additives in the NPH that slow the onset, peak, and duration of activity in the long-acting insulin.

In which order will the nurse take these steps to prepare NPH 20 units and regular insulin 2 units using the same syringe? (Put a comma and a space between each answer choice [A, B, C, D, E]). a. Rotate NPH vial. b. Withdraw regular insulin. c. Withdraw 20 units of NPH. d. Inject 20 units of air into NPH vial. e. Inject 2 units of air into regular insulin vial.

ANS: D Muscle strength of 3 indicates the patient is unable to move against resistance but can move against gravity. Level 1 indicates minimal muscle contraction, level 2 indicates the arm can move when gravity is eliminated, and level 4 indicates active movement with some resistance.

The nurse finds that a patient can flex the arms when no resistance is applied but is unable to flex against light resistance. How should the nurse document the patient's muscle strength level? a. 0 b. 1 c. 2 d. 3

ANS: A The "rule of 15" indicates that administration of quickly acting carbohydrates should be done two or three times for a conscious patient whose glucose remains less than 70 mg/dL before notifying the health care provider. More complex carbohydrates and fats may be used after the glucose has stabilized. Glucagon should be used if the patient's level of consciousness decreases so that oral carbohydrates can no longer be given.

The nurse has administered 4 oz of orange juice to an alert patient whose blood glucose was 62 mg/dL. Fifteen minutes later, the blood glucose is 67 mg/dL. Which action should the nurse take next? a. Give the patient 4 to 6 oz more orange juice. b. Administer the PRN glucagon (Glucagon) 1 mg IM. c. Have the patient eat some peanut butter with crackers. d. Notify the health care provider about the hypoglycemia.

ANS: A Patients with impaired renal function are at risk for decreased renal function after IVP because the contrast medium used is nephrotoxic, so the nurse should monitor the patient's urine output. MAC sedation and retention catheterization are not required for the procedure. The contrast medium is given IV, not orally

The nurse is caring for a hospitalized patient with a decreased glomerular filtration rate who is scheduled for an intravenous pyelogram (IVP). Which action will be included in the plan of care? a. Monitor the urine output after the procedure. b. Assist with monitored anesthesia care (MAC). c. Give oral contrast solution before the procedure. d. Insert a large size urinary catheter before the IVP.

ANS: B A drop in the weight of more than 2 kg indicates severe dehydration, and the test should be discontinued. The other assessment data are not unusual with this test.

The nurse is caring for a patient during a water deprivation test. Which finding is most important for the nurse to communicate to the health care provider? a. The patient reports intense thirst. b. The patient has a 5-lb (2.3-kg) weight loss. c. The patient feels dizzy when sitting on the bed. d. The patient's urine osmolality does not increase.

ANS: B Because contrast media may cause acute kidney injury in patients with poor renal function, the health care provider will need to prescribe therapies such as IV fluids to prevent this complication. The other findings are consistent with the patient's diagnosis of a pituitary tumor

The nurse is caring for a patient with a possible pituitary tumor who is scheduled for a computed tomography scan with contrast. Which information about the patient is importantto discuss with the health care provider before the test? a. Report of chronic headache b. History of renal insufficiency c. Recent bilateral visual field loss d. Blood glucose level of 134 mg/dL

ANS: C A distended bladder may be palpable above the symphysis pubis. Palpation would not be helpful in assessing for the other listed urinary tract information

The nurse is examining an adult patient. For what purpose would the nurse use palpation? a. Determining kidney function b. Identifying renal artery bruits c. Checking for bladder distention d. Assessing for ureteral peristalsis

ANS: B Crackling sounds and a grating sensation that accompany movement are described as crepitus or crepitation. Torticollis is a twisting of the neck to one side, subluxation is a partial dislocation of the joint, and epicondylitis is an inflammation of the elbow causing a dull ache that increases with movement.

The nurse notes crackling sounds and a grating sensation with palpation of an older patient's elbow. How should this finding be documented? a. Torticollis b. Crepitation c. Subluxation d. Epicondylitis

ANS: D The decreased height and the patient's age suggest that the patient may have osteoporosis, and bone density testing is needed. Discography, MRI, and myelography are typically done for patients with current symptoms caused by musculoskeletal dysfunction and are not the initial diagnostic tests for osteoporosis

The nurse notes that a 59-yr-old female patient has lost 1 inch in height over the past 2 years. What diagnostic test should the nurse plan to discuss with the patient? a. Discography studies b. Myelographic testing c. Magnetic resonance imaging (MRI) d. Dual-energy x-ray absorptiometry (DXA)

ANS: B, C, D, F Blood pressure, serum creatinine, urine testing for microalbuminuria, and monofilament testing of the foot are recommended at least annually to screen for possible microvascular and macrovascular complications of diabetes. Chest x-ray and CBC might be ordered if the patient with diabetes presents with symptoms of respiratory or infectious problems but are not routinely included in screening.

To monitor for complications in a patient with type 2 diabetes, which tests will the nurse in the diabetic clinic schedule at least annually? (Select all that apply.) a. Chest x-ray b. Blood pressure c. Serum creatinine d. Urine for microalbuminuria e. Complete blood count (CBC) f. Monofilament testing of the foot

ANS: B, C, D, F Blood pressure, serum creatinine, urine testing for microalbuminuria, and monofilament testing of the foot are recommended at least annually to screen for possible microvascular and macrovascular complications of diabetes. Chest x-ray and CBC might be ordered if the patient with diabetes presents with symptoms of respiratory or infectious problems but are not routinely included in screening.

To monitor for complications in a patient with type 2 diabetes, which tests will the nurse in the diabetic clinic schedule at least annually? (Select all that apply.) a. Chest x-ray b. Blood pressure c. Serum creatinine d. Urine for microalbuminuria e. Complete blood count (CBC) f. Monofilament testing of the foot

ANS: C Normally the urinalysis will show zero to trace amounts of protein, but some medications may give false-positive readings. The other actions by the nurse may be appropriate but checking for medications that may affect the dipstick accuracy should be first.

What action should the nurse take first when a patient's urine dipstick test indicates a small amount of protein? a. Send a urine specimen to the laboratory to test for ketones. b. Obtain a clean-catch urine for culture and sensitivity testing. c. Inquire about which medications the patient is currently taking. d. Ask the patient about any family history of chronic renal failure.

ANS: A The creatinine clearance approximates the GFR. The other responses are not accurate.

What glomerular filtration rate (GFR) would the nurse estimate for a 30-yr-old patient with a creatinine clearance result of 60 mL/min? a. 60 mL/min b. 90 mL/min c. 120 mL/min d. 180 mL/min

ANS: C Glycosylated hemoglobin testing measures glucose control over the last 3 months. Glucose testing before/after a meal or random testing may reveal impaired glucose tolerance and indicate prediabetes, but it is not done on patients who already have a diagnosis of diabetes. There is no test to evaluate for hypoglycemic episodes in the past.

What information will a review of a patient's glycosylated hemoglobin (A1C) results provide to the nurse? a. Fasting preprandial glucose levels b. Glucose levels 2 hours after a meal c. Glucose control over the past 90 days d. Hypoglycemic episodes in the past 3 months

ANS: B The specimen must be kept on ice or refrigerated until the collection is finished. Voided or catheterized specimens are acceptable for the test. The initial voided specimen is discarded. There is no fluid intake requirement for the 24-hour collection.

What should the nurse teach a patient who is scheduled to complete a 24-hour urine collection for 17 ketosteroids? a. To insert and maintain a retention catheter b. To keep the specimen refrigerated or on ice c. To drink at least 3 L of fluid during the 24 hours d. To void and save the specimen to start the collection

ANS: B Pink-tinged urine and urinary frequency are expected after cystoscopy. Burning on urination is common, but pain that requires opioids for relief is not expected. A good fluid intake is encouraged after this procedure. Bed rest is not required after cystoscopy.

When caring for a patient after cystoscopy, what should the nurse include in the plan of care? a. The patient learns to request narcotics for pain. b. The patient understands to expect blood-tinged urine. c. The patient restricts activity to bed rest for 4 to 6 hours. d. The patient remains NPO for 8 hours to prevent vomiting.

ANS: D LPN/VN education includes common procedures such as catheterization of stable patients. The other patients require complex assessments or patient teaching that are included in registered nurse (RN) education and scope of practice.

When working in the urology/nephrology clinic, which patient's care could the nurse delegate to an experienced licensed practical/vocational nurse (LPN/VN)? a. Patient who is scheduled for a renal biopsy after a recent kidney transplant. b. Patient who will need monitoring for several hours after a renal arteriogram. c. Patient who requires teaching about possible post-cystoscopy complications. d. Patient who will have catheterization to check for residual urine after voiding

ANS: A When performing the straight leg-raising test, nurse passively lifts the patient's legs to a 60-degree angle while the patient is in the supine position. The other actions would not be correct for this test

Which action should the nurse include when performing the straight-leg raising test for an ambulatory patient with back pain? a. Lift the patient's leg to a 60-degree angle from the bed. b. Place the patient in the prone position on the exam table. c. Ask the patient to dangle both legs over the edge of the exam table. d. Instruct the patient to elevate the legs and tense the abdominal muscles.

ANS: B Part of the total calcium is bound to albumin, so hypoalbuminemia can lead to misinterpretation of calcium levels. The other laboratory values will not affect total calcium interpretation.

Which additional information should the nurse consider when reviewing the laboratory results for a patient's total calcium level? a. The blood glucose b. The serum albumin c. The phosphate level d. The magnesium level

ANS:D A history of falls is a safety issue that requires further assessment and development of fall prevention strategies. The other changes may require additional attention but are less urgent.

Which finding for a 77-yr-old patient seen in the outpatient clinic is the highest priority for further nursing assessment and intervention? a. Symmetric joint swelling of fingers b. Decreased right knee range of motion c. Report of left hip aching when jogging d. History of recent loss of balance and fall

ANS: A The presence of purulent (cloudy) fluid suggests a possible joint infection. Normal synovial fluid is scant in amount and pale yellow/straw-colored.

Which finding from analysis of fluid from a patient's right knee arthrocentesis should be of concern to the nurse? a. Cloudy fluid b. Scant thin fluid c. Pale yellow fluid d. Straw-colored fluid

ANS: B Corticosteroids can affect blood glucose results. The other information will not affect the test results.

Which information about a patient who is scheduled for an oral glucose tolerance test should the nurse consider in interpreting the test results? a. The patient reports having occasional orthostatic dizziness. b. The patient takes oral corticosteroids for rheumatoid arthritis. c. The patient has had a 10 pound weight gain in the last month. d. The patient drank several glasses of water an hour previously.

ANS: C The increased number of white blood cells (WBCs) indicates the presence of urinary tract infection or inflammation. The other findings are normal.

Which information from a patient's urinalysis requires that the nurse notify the health care provider? a. pH 6.2 b. Trace protein c. WBC 20 to 26/hpf d. Specific gravity 1.021

ANS: C A family history of height loss with aging may indicate osteoporosis, and the nurse should perform a more thorough assessment of the patient's current height and other risk factors for osteoporosis. A sprained ankle during adolescence does not place the patient at increased current risk for musculoskeletal problems. A family history of tuberculosis is not a risk factor. Occasional nonsteroidal antiinflammatory drug (NSAID) use does not indicate any increased musculoskeletal risk.

Which information in a 67-yr-old woman's health history should alert the nurse to the need for a focused assessment of the musculoskeletal system? a. The patient sprained her ankle at age 13. b. The patient's father died of tuberculosis. c. The patient's mother became shorter with aging. d. The patient takes ibuprofen for occasional headaches.

ANS: C The patient's height and weight indicate obesity, which places stress on weight-bearing joints and predisposes the patient to osteoarthritis. The use of whole milk, avoidance of fruits and vegetables, and use of a daily multivitamin are not risk factors for musculoskeletal problems.

Which information obtained during the nurse's assessment may indicate a patient's increased risk for musculoskeletal problems? a. The patient takes a multivitamin daily. b. The patient dislikes fruits and vegetables. c. The patient is 5 ft, 2 in tall and weighs 180 lb. d. The patient prefers whole milk to nonfat milk.

ANS: C A low TSH level indicates that the patient's hypothyroidism is caused by decreased anterior pituitary secretion of TSH. Low T3and T4 levels are not diagnostic of the primary cause of the hypothyroidism. TRH levels indicate the function of the hypothalamus.

Which laboratory value should the nurse review to determine whether a patient's hypothyroidism is caused by a problem with the anterior pituitary gland? a. Thyroxine (T4) level b. Triiodothyronine (T3) level c. Thyroid-stimulating hormone (TSH) level d. Thyrotropin-releasing hormone (TRH) level

ANS: B Frequent or chronic corticosteroid use may lead to skeletal problems such as avascular necrosis and osteoporosis. The use of HRT and calcium supplements will help prevent osteoporosis. NSAID use does not increase the risk for musculoskeletal problems.

Which medication information should the nurse identify as a potential risk to a patient's musculoskeletal system? a. The patient takes a daily multivitamin and calcium supplement. b. The patient has asthma requiring frequent therapy with oral corticosteroids. c. The patient takes hormone replacement therapy (HRT) to prevent "hot flashes." d. The patient has headaches treated with nonsteroidal antiinflammatory drugs (NSAIDs).

ANS: A Nonsteroidal antiinflammatory medications (NSAIDs) are nephrotoxic and should be avoided in patients with impaired renal function. The nurse should also ask about reasons the patient is taking the other medications, but the medication of most concern is the ibuprofen

Which medication taken by a patient with decreased renal function will be of most concern to the nurse? a. ibuprofen (Motrin) b. warfarin (Coumadin) c. folic acid (vitamin B9) d. penicillin (Bicillin C-R)

ANS: A Checking systolic pressure at the ankle and brachial areas and calculating the ankle-brachial index is a procedure that can be done by UAP who have been trained in the procedure. The other assessments require more education and critical thinking and should be done by the registered nurse (RN)

Which nursing action can the nurse delegate to experienced unlicensed assistive personnel (UAP) who are working in the diabetic clinic? a. Measure the ankle-brachial index. b. Check for changes in skin pigmentation. c. Assess for unilateral or bilateral foot drop. d. Ask the patient about symptoms of depression.

Check for changes in skin pigmentation. c. Assess for unilateral or bilateral foot drop. d. Ask the patient about symptoms of depression.

ANS: C A pressure dressing is applied, and the patient is kept on the affected side for 30 to 60 minutes to put pressure on the biopsy side and decrease the risk for bleeding. The blood glucose and BUN/creatinine will not be affected by the biopsy. Although monitoring for hematuria is needed, there is no need for catheterization.

Which nursing action is essential for a patient immediately after a renal biopsy? a. Insert a urinary catheter and test urine for microscopic hematuria. b. Check blood glucose to assess for hyperglycemia or hypoglycemia. c. Apply a pressure dressing and position the patient on the affected side. d. Monitor blood urea nitrogen (BUN) and creatinine to assess renal function.

ANS: C Because exenatide slows gastric emptying, oral medications should be taken at least 1 hour before the exenatide to avoid slowing absorption. Exenatide is injected and increases feelings of satiety. Hypoglycemia can occur with this medication.

Which patient statement indicates that the nurse's teaching about exenatide (Byetta) has been effective? a. "I may feel hungrier than usual when I take this medicine." b. "I will not need to worry about hypoglycemia with the Byetta." c. "I should take my daily aspirin at least an hour before the Byetta." d. "I will take the pill at the same time I eat breakfast in the morning."

"I will not need to worry about hypoglycemia with the Byetta." c. "I should take my daily aspirin at least an hour before the Byetta." d. "I will take the pill at the same time I eat breakfast in the morning."

ANS: C Because thyroid function affects metabolic rate, changes in weight may indicate hyperfunction or hypofunction of the thyroid gland. Nocturia, visual difficulty, and changes in stress level are associated with other endocrine disorders.

Which question from the nurse during a patient interview will provide focused information about a possible thyroid disorder? a. "What methods do you use to help cope with stress?" b. "Have you experienced any blurring or double vision?" c. "Have you had a recent unplanned weight gain or loss?" d. "Do you have to get up at night to empty your bladder?"

ANS: D Dysuria is painful urination. The alternate responses can be used to assess other urinary tract symptoms: hematuria, nocturia, and frequency

Which question should the nurse ask to assess a patient's dysuria? a. "Do you have to urinate at night?" b. "Do you have blood in your urine?" c. "Do you have to urinate frequently?" d. "Do you have pain when you urinate?"

ANS: C For some patients with type 2 diabetes, changes in lifestyle are sufficient to achieve blood glucose control. Insulin is frequently used for type 2 diabetes, complications are equally severe as for type 1 diabetes, and type 2 diabetes is usually diagnosed with routine laboratory testing or after a patient develops complications such as frequent yeast infections.

Which statement by a nurse to a patient newly diagnosed with type 2 diabetes is accurate? a. Insulin is not used to control blood glucose in patients with type 2 diabetes. b. Complications of type 2 diabetes are less serious than those of type 1 diabetes. c. Changes in diet and exercise may control blood glucose levels in type 2 diabetes. d. Type 2 diabetes is usually diagnosed when a patient is admitted in hyperglycemic coma

ANS: D The patient's elevated temperature may indicate a bladder infection, a possible complication of cystoscopy. The health care provider should be notified so that antibiotic therapy can be started. Pink-tinged urine is expected after a cystoscopy. The insomnia and bruising should be discussed further with the patient but do not indicate a need to notify the health care provider.

Which statement by a patient who had a cystoscopy the previous day should the nurse report immediately to the health care provider? a. "My urine looks pink." b. "My IV site is bruised." c. "My sleep was restless." d. "My temperature is 101."

ANS: C Difficulty in swallowing can occur with a goiter. Nocturia is associated with diseases such as diabetes, diabetes insipidus, or chronic kidney disease. Breast tenderness would occur with excessive gonadal hormone levels. Thirst is a sign of disease such as diabetes.

Which statement made by a 50-yr-old female patient indicates to the nurse that further assessment of thyroid function may be needed? a. "I am so thirsty that I drink all day long." b. "I get up several times at night to urinate." c. "I feel a lump in my throat when I swallow." d. "I notice my breasts are always tender lately."

ANS: A, C, E Smoking may affect the results of oral glucose tolerance tests. Blood samples are obtained at baseline and at 30, 60, and 120 minutes. Accuracy requires that the patient be fasting before the test. The patient should consume at least 1500 calories/day for 3 days before the test. The patient should be ambulatory and active for accurate test results.

Which statements will the nurse include when teaching a patient who is scheduled for oral glucose tolerance testing in the outpatient clinic? (Select all that apply.) a. "You will need to avoid smoking before the test." b. "Exercise should be avoided until the testing is complete." c. "Several blood samples will be obtained during the testing." d. "You should follow a low-calorie diet the day before the test." e. "The test requires that you fast for at least 8 hours before testing."

ANS: B In clinic setting, drawing blood specimens is a common skill performed by UAP who are trained. The other actions are assessments and require registered nurse (RN)-level judgment and critical thinking.

Which task can the nurse assign to unlicensed assistive personnel (UAP) who are working in the orthopedic clinic? a. Grade leg muscle strength for a patient with back pain. b. Obtain blood sample for uric acid from a patient with gout. c. Perform straight-leg-raise testing for a patient with sciatica. d. Check for knee joint crepitation before arthroscopic surgery.
