Which action can the registered nurse (RN) who is caring for a critically ill patient with multiple IV lines and medications delegate to a licensed practical/vocational nurse (LPN/LVN)? a. Flush a saline lock with normal saline. b. Verify blood products prior to administration. c. Remove the patient's central venous catheter. d. Titrate the flow rate of vasoactive IV medications.

ANS: A A LPN/LVN has the education, experience, and scope of practice to flush a saline lock with normal saline. Administration of blood products, adjustment of vasoactive infusion rates, and removal of central catheters in critically ill patients require RN level education and scope of practice.

A nurse is caring for a client who has the following laboratory results: potassium 3.4 mEq/L, magnesium 1.8 mEq/L, calcium 8.5 mEq/L, sodium 144 mEq/L. Which assessment should the nurse complete first? a. Depth of respirations b. Bowel sounds c. Grip strength d. Electrocardiography

ANS: A A client with a low serum potassium level may exhibit hypoactive bowel sounds, cardiac dysrhythmias, and muscle weakness resulting in shallow respirations and decreased handgrips. The nurse should assess the client's respiratory status first to ensure respirations are sufficient. The respiratory assessment should include rate and depth of respirations, respiratory effort, and oxygen saturation. The other assessments are important but are secondary to the client's respiratory status.

A nurse is assessing clients on a medical-surgical unit. Which client is at risk for hypokalemia? a. Client with pancreatitis who has continuous nasogastric suctioning b. Client who is prescribed an angiotensin-converting enzyme (ACE) inhibitor c. Client in a motor vehicle crash who is receiving 6 units of packed red blood cells d. Client with uncontrolled diabetes and a serum pH level of 7.33

ANS: A A client with continuous nasogastric suctioning would be at risk for actual potassium loss leading to hypokalemia. The other clients are at risk for potassium excess or hyperkalemia.

A nurse assesses a client who is prescribed a medication that inhibits angiotensin I from converting into angiotensin II (angiotensin-converting enzyme [ACE] inhibitor). For which expected therapeutic effect should the nurse assess? a. Blood pressure decrease from 180/72 mm Hg to 144/50 mm Hg b. Daily weight increase from 55 kg to 57 kg c. Heart rate decrease from 100 beats/min to 82 beats/min d. Respiratory rate increase from 12 breaths/min to 15 breaths/min

ANS: A ACE inhibitors will disrupt the renin-angiotensin II pathway and prevent the kidneys from reabsorbing water and sodium. The kidneys will excrete more water and sodium, decreasing the client's blood pressure.

A nurse evaluates a client's arterial blood gas values (ABGs): pH 7.30, PaO2 86 mm Hg, PaCO2 55 mm Hg, and HCO3- 22 mEq/L. Which intervention should the nurse implement first? a. Assess the airway. b. Administer prescribed bronchodilators. c. Provide oxygen. d. Administer prescribed mucolytics.

ANS: A All interventions are important for clients with respiratory acidosis; this is indicated by the ABGs. However, the priority is assessing and maintaining an airway. Without a patent airway, other interventions will not be helpful.

A postoperative patient who had surgery for a perforated gastric ulcer has been receiving nasogastric suction for 3 days. The patient now has a serum sodium level of 127 mEq/L (127 mmol/L). Which prescribed therapy should the nurse question? a. Infuse 5% dextrose in water at 125 mL/hr. b. Administer 3% saline at 50 mL/hr for a total of 200 mL. c. Administer IV morphine sulfate 4 mg every 2 hours PRN. d. Give IV metoclopramide (Reglan) 10 mg every 6 hours PRN for nausea.

ANS: A Because the patient's gastric suction has been depleting electrolytes, the IV solution should include electrolyte replacement. Solutions such as lactated Ringer's solution would usually be ordered for this patient. The other orders are appropriate for a postoperative patient with gastric suction.

A nurse is assessing clients for fluid and electrolyte imbalances. Which client should the nurse assess first for potential hyponatremia? a. A 34-year-old on NPO status who is receiving intravenous D5W b. A 50-year-old with an infection who is prescribed a sulfonamide antibiotic c. A 67-year-old who is experiencing pain and is prescribed ibuprofen (Motrin) d. A 73-year-old with tachycardia who is receiving digoxin (Lanoxin)

ANS: A Dextrose 5% in water (D5W) contains no electrolytes. Because the client is not taking any food or fluids by mouth (NPO), normal sodium excretion can lead to hyponatremia. The sulfonamide antibiotic, ibuprofen, and digoxin will not put a client at risk for hyponatremia.

A nurse assesses a client who is experiencing an acid-base imbalance. The client's arterial blood gas values are pH 7.34, PaO2 88 mm Hg, PaCO2 38 mm Hg, and HCO3- 19 mEq/L. Which assessment should the nurse perform first? a. Cardiac rate and rhythm b. Skin and mucous membranes c. Musculoskeletal strength d. Level of orientation

ANS: A Early cardiovascular changes for a client experiencing moderate acidosis include increased heart rate and cardiac output. As the acidosis worsens, the heart rate decreases and electrocardiographic changes will be present. Central nervous system and neuromuscular system changes do not occur with mild acidosis and should be monitored if the acidosis worsens. Skin and mucous membrane assessment is not a priority now, but will change as acidosis worsens.

When caring for a patient with renal failure on a low phosphate diet, the nurse will inform unlicensed assistive personnel (UAP) to remove which food from the patient's food tray? a. Skim milk c. Mixed green salad b. Grape juice d. Fried chicken breast

ANS: A Foods high in phosphate include milk and other dairy products, so these are restricted on low-phosphate diets. Green, leafy vegetables; high-fat foods; and fruits and juices are not high in phosphate and are not restricted.

A patient receives 3% NaCl solution for correction of hyponatremia. Which assessment is most important for the nurse to monitor for while the patient is receiving this infusion? a. Lung sounds c. Peripheral pulses b. Urinary output d. Peripheral edema

ANS: A Hypertonic solutions cause water retention, so the patient should be monitored for symptoms of fluid excess. Crackles in the lungs may indicate the onset of pulmonary edema and are a serious manifestation of fluid excess. Peripheral pulses, peripheral edema, or changes in urine output are also important to monitor when administering hypertonic solutions, but they do not indicate acute respiratory or cardiac decompensation.

A patient has a serum calcium level of 7.0 mEq/L. Which assessment finding is most important for the nurse to report to the health care provider? a. The patient is experiencing laryngeal stridor. b. The patient complains of generalized fatigue. c. The patient's bowels have not moved for 4 days. d. The patient has numbness and tingling of the lips.

ANS: A Hypocalcemia can cause laryngeal stridor, which may lead to respiratory arrest. Rapid action is required to correct the patient's calcium level. The other data are also consistent with hypocalcemia, but do not indicate a need for as immediate action as laryngospasm.

A patient who has been receiving diuretic therapy is admitted to the emergency department with a serum potassium level of 3.0 mEq/L. The nurse should alert the health care provider immediately that the patient is on which medication? a. Digoxin (Lanoxin) 0.25 mg/day b. Metoprolol (Lopressor) 12.5 mg/day c. Ibuprofen (Motrin) 400 mg every 6 hours d. Lantus insulin 24 U subcutaneously every evening

ANS: A Hypokalemia increases the risk for digoxin toxicity, which can cause serious dysrhythmias. The nurse will also need to do more assessment regarding the other medications, but they are not of as much concern with the potassium level.

A patient has a magnesium level of 1.3 mg/dL. Which assessment would help the nurse identify a likely cause of this value? a. Daily alcohol intake b. Dietary protein intake c. Multivitamin/mineral use d. Over-the-counter (OTC) laxative use

ANS: A Hypomagnesemia is associated with alcoholism. Protein intake would not have a significant effect on magnesium level. OTC laxatives (such as milk of magnesia) and use of multivitamin/mineral supplements tend to increase magnesium levels.

The nurse teaches a patient who is experiencing stress at work how to use imagery as a relaxation technique. Which statement by the nurse would be appropriate? a. "Think of a place where you feel peaceful and comfortable." b. "Place the stress in your life into an image that you can destroy." c. "Repeatedly visualize yourself experiencing the distress in your workplace." d. "Bring what you hear and sense in your work environment into your image."

ANS: A Imagery is the use of one's mind to generate images that have a calming effect on the body. When using imagery for relaxation, the patient should visualize a comfortable and peaceful place. The goal is to offer a relaxing retreat from the actual work environment. Imagery that is not intended for relaxation purposes can target a disease, problem, or stressor.

A nurse is assessing a client with hypokalemia, and notes that the client's handgrip strength has diminished since the previous assessment 1 hour ago. Which action should the nurse take first? a. Assess the client's respiratory rate, rhythm, and depth. b. Measure the client's pulse and blood pressure. c. Document findings and monitor the client. d. Call the health care provider.

ANS: A In a client with hypokalemia, progressive skeletal muscle weakness is associated with increasing severity of hypokalemia. The most life-threatening complication of hypokalemia is respiratory insufficiency. It is imperative for the nurse to perform a respiratory assessment first to make sure that the client is not in immediate jeopardy. Cardiac dysrhythmias are also associated with hypokalemia. The client's pulse and blood pressure should be assessed after assessing respiratory status. Next, the nurse would call the health care provider to obtain orders for potassium replacement. Documenting findings and continuing to monitor the client should occur during and after potassium replacement therapy.

A nurse assesses a client who is admitted with an acid-base imbalance. The client's arterial blood gas values are pH 7.32, PaO2 85 mm Hg, PaCO2 34 mm Hg, and HCO3- 16 mEq/L. What action should the nurse take next? a. Assess client's rate, rhythm, and depth of respiration. b. Measure the client's pulse and blood pressure. c. Document the findings and continue to monitor. d. Notify the physician as soon as possible.

ANS: A Progressive skeletal muscle weakness is associated with increasing severity of acidosis. Muscle weakness can lead to severe respiratory insufficiency. Acidosis does lead to dysrhythmias (due to hyperkalemia), but these would best be assessed with cardiac monitoring. Findings should be documented, but simply continuing to monitor is not sufficient. Before notifying the physician, the nurse must have more data to report.

A patient who is taking antiretroviral medication to control human immunodeficiency virus (HIV) infection tells the nurse about feeling mildly depressed and anxious. Which additional information about the patient is mostimportant to communicate to the health care provider? a. The patient takes vitamin supplements and St. John's wort. b. The patient recently experienced the death of a close friend. c. The patient's blood pressure has increased to 152/88 mm Hg. d. The patient expresses anxiety about whether the drugs are effective.

ANS: A St. John's wort interferes with metabolism of medications that use the cytochrome P450 enzyme system, including many HIV medications. The health care provider will need to check for toxicity caused by the drug interactions. Teaching is needed about drug interactions. The other information will also be reported but does not have immediate serious implications for the patient's health.

A nurse is caring for a client who has just experienced a 90-second tonic-clonic seizure. The client's arterial blood gas values are pH 6.88, PaO2 50 mm Hg, PaCO2 60 mm Hg, and HCO3- 22 mEq/L. Which action should the nurse take first? a. Apply oxygen by mask or nasal cannula. b. Apply a paper bag over the client's nose and mouth. c. Administer 50 mL of sodium bicarbonate intravenously. d. Administer 50 mL of 20% glucose and 20 units of regular insulin.

ANS: A The client has experienced a combination of metabolic and acute respiratory acidosis through heavy skeletal muscle contractions and no gas exchange. When the seizures have stopped and the client can breathe again, the fastest way to return acid-base balance is to administer oxygen. Applying a paper bag over the client's nose and mouth would worsen the acidosis. Sodium bicarbonate should not be administered because the client's arterial bicarbonate level is normal. Glucose and insulin are administered together to decrease serum potassium levels. This action is not appropriate based on the information provided.

A patient with renal failure who arrives for outpatient hemodialysis is unresponsive to questions and has decreased deep tendon reflexes. Family members report that the patient has been taking aluminum hydroxide/magnesium hydroxide suspension (Maalox) at home for indigestion. Which action should the nurse take first? a. Notify the patient's health care provider. b. Obtain an order to draw a potassium level. c. Review the last magnesium level on the patient's chart. d. Teach the patient about magnesium-containing antacids.

ANS: A The health care provider should be notified immediately. The patient has a history and manifestations consistent with hypermagnesemia. The nurse should check the chart for a recent serum magnesium level and make sure that blood is sent to the laboratory for immediate electrolyte and chemistry determinations. Dialysis should correct the high magnesium levels. The patient needs teaching about the risks of taking magnesium-containing antacids. Monitoring of potassium levels also is important for patients with renal failure, but the patient's current symptoms are not consistent with hyperkalemia.

An adult patient who is hospitalized after a motorcycle crash tells the nurse, "I didn't sleep last night because I worried about missing work at my new job and losing my insurance coverage." Which nursing diagnosis is appropriate to include in the plan of care? a. Anxiety c. Ineffective denial b. Defensive coping d. Risk prone health behavior

ANS: A The information about the patient indicates that anxiety is an appropriate nursing diagnosis. The patient data do not support defensive coping, ineffective denial, or risk prone health behavior as problems for this patient.

A patient who is lethargic and exhibits deep, rapid respirations has the following arterial blood gas (ABG) results: pH 7.32, PaO288 mm Hg, PaCO237 mm Hg, and HCO316 mEq/L. How should the nurse interpret these results? a. Metabolic acidosis c. Respiratory acidosis b. Metabolic alkalosis d. Respiratory alkalosis

ANS: A The pH and HCO3indicate that the patient has a metabolic acidosis. The ABGs are inconsistent with the other responses.

Following a thyroidectomy, a patient complains of "a tingling feeling around my mouth." Which assessment should the nurse complete? a. Presence of the Chvostek's sign b. Abnormal serum potassium level c. Decreased thyroid hormone level d. Bleeding on the patient's dressing

ANS: A The patient's symptoms indicate possible hypocalcemia, which can occur secondary to parathyroid injury or removal during thyroidectomy. There is no indication of a need to check the potassium level, the thyroid hormone level, or for bleeding.

A nurse is caring for a client who has chronic emphysema and is receiving oxygen therapy at 6 L/min via nasal cannula. The following clinical data are available: pH = 7.28- PaO2 = 85 mm Hg- PaCO2 = 55 mm Hg- HCO3- = 26 mEq/L- Pulse rate = 96 beats/min- Blood pressure = 135/45- Respiratory rate = 6 breaths/min- O2 saturation = 88% Which action should the nurse take first? a. Notify the Rapid Response Team and provide ventilation support. b. Change the nasal cannula to a mask and reassess in 10 minutes. c. Place the client in Fowler's position if he or she is able to tolerate it. d. Decrease the flow rate of oxygen to 2 to 4 L/min, and reassess.

ANS: A The primary trigger for respiration in a client with chronic respiratory acidosis is a decreased arterial oxygen level (hypoxic drive). Oxygen therapy can inhibit respiratory efforts in this case, eventually causing respiratory arrest and death. The nurse could decrease the oxygen flow rate; eventually, this might improve the client's respiratory rate, but the priority action would be to call the Rapid Response Team whenever a client with chronic carbon dioxide retention has a respiratory rate less than 10 breaths/min. Changing the cannula to a mask does nothing to improve the client's hypoxic drive, nor would it address the client's most pressing need. Positioning will not help the client breathe at a normal rate or maintain client safety.

A nurse assesses a client with diabetes mellitus who is admitted with an acid-base imbalance. The client's arterial blood gas values are pH 7.36, PaO2 98 mm Hg, PaCO2 33 mm Hg, and HCO3- 18 mEq/L. Which manifestation should the nurse identify as an example of the client's compensation mechanism? a. Increased rate and depth of respirations b. Increased urinary output c. Increased thirst and hunger d. Increased release of acids from the kidneys

ANS: A This client has metabolic acidosis. The respiratory system compensates by increasing its activity and blowing off excess carbon dioxide. Increased urinary output, thirst, and hunger are manifestations of hyperglycemia but are not compensatory mechanisms for acid-base imbalances. The kidneys do not release acids.

The nurse notes a serum calcium level of 7.9 mg/dL for a patient who has chronic malnutrition. Which action should the nurse take next? a. Monitor ionized calcium level. b. Give oral calcium citrate tablets. c. Check parathyroid hormone level. d. Administer vitamin D supplements.

ANS: A This patient with chronic malnutrition is likely to have a low serum albumin level, which will affect the total serum calcium. A more accurate reflection of calcium balance is the ionized calcium level. Most of the calcium in the blood is bound to protein (primarily albumin). Alterations in serum albumin levels affect the interpretation of total calcium levels. Low albumin levels result in a drop in the total calcium level, although the level of ionized calcium is not affected. The other actions may be needed if the ionized calcium is also decreased.

A nurse assesses a client who is experiencing an acid-base imbalance. The client's arterial blood gas values are pH 7.32, PaO2 94 mm Hg, PaCO2 34 mm Hg, and HCO3- 18 mEq/L. For which clinical manifestations should the nurse assess? (Select all that apply.) a. Reduced deep tendon reflexes b. Drowsiness c. Increased respiratory rate d. Decreased urinary output e. Positive Trousseau's sign

ANS: A, B, C Metabolic acidosis causes neuromuscular changes, including reduced muscle tone and deep tendon reflexes. Clients usually present with lethargy and drowsiness. The respiratory system will attempt to compensate for the metabolic acidosis; therefore, respirations will increase rate and depth. A positive Trousseau's sign is associated with alkalosis. Decreased urine output is not a manifestation of metabolic acidosis.

A nurse is planning interventions that regulate acid-base balance to ensure the pH of a client's blood remains within the normal range. Which abnormal physiologic functions may occur if the client experiences an acid-base imbalance? (Select all that apply.) a. Reduction in the function of hormones b. Fluid and electrolyte imbalances c. Increase in the function of selected enzymes d. Excitable cardiac muscle membranes e.Increase in the effectiveness of many drugs

ANS: A, B, E Acid-base imbalances interfere with normal physiology, including reducing the function of hormones and enzymes, causing fluid and electrolyte imbalances, making heart membranes more excitable, and decreasing the effectiveness of many drugs.

A nurse is assessing clients on a medical-surgical unit. Which clients are at increased risk for hypophosphatemia? (Select all that apply.) a. A 36-year-old who is malnourished b. A 42-year-old with uncontrolled diabetes c. A 50-year-old with hyperparathyroidism d. A 58-year-old with chronic renal failure e. A 76-year-old who is prescribed antacids

ANS: A, B, E Clients at risk for hypophosphatemia include those who are malnourished, those with uncontrolled diabetes mellitus, and those who use aluminum hydroxide-based or magnesium-based antacids. Hyperparathyroidism and chronic renal failure are common causes of hyperphosphatemia.

A nurse assesses a client who is admitted for treatment of fluid overload. Which manifestations should the nurse expect to find? (Select all that apply.) a. Increased pulse rate b. Distended neck veins c. Decreased blood pressure d. Warm and pink skin e. Skeletal muscle weakness

ANS: A, B, E Manifestations of fluid overload include increased pulse rate, distended neck veins, increased blood pressure, pale and cool skin, and skeletal muscle weakness.

A nurse is caring for clients with electrolyte imbalances on a medical-surgical unit. Which clinical manifestations are correctly paired with the contributing electrolyte imbalance?(Select all that apply.) a. Hypokalemia - Flaccid paralysis with respiratory depression b. Hyperphosphatemia - Paresthesia with sensations of tingling and numbness c. Hyponatremia - Decreased level of consciousness d. Hypercalcemia - Positive Trousseau's and Chvostek's signs e. Hypomagnesemia - Bradycardia, peripheral vasodilation, and hypotension

ANS: A, C Flaccid paralysis with respiratory depression is associated with hypokalemia. Decreased level of consciousness is associated with hyponatremia. Paresthesia with sensations of tingling and numbness is associated with hypophosphatemia or hypercalcemia. Positive Trousseau's and Chvostek's signs are associated with hypocalcemia or hyperphosphatemia. Bradycardia, peripheral vasodilation, and hypotension are associated with hypermagnesemia.

A nurse is assessing a client who has an electrolyte imbalance related to renal failure. For which potential complications of this electrolyte imbalance should the nurse assess? (Select all that apply.) a. Electrocardiogram changes b. Slow, shallow respirations c. Orthostatic hypotension d. Paralytic ileus e. Skeletal muscle weakness

ANS: A, D, E Electrolyte imbalances associated with acute renal failure include hyperkalemia and hyperphosphatemia. The nurse should assess for electrocardiogram changes, paralytic ileus caused by decrease bowel mobility, and skeletal muscle weakness in clients with hyperkalemia. The other choices are potential complications of hypokalemia.

A nurse assesses a client who is receiving total parenteral nutrition. For which adverse effects related to an acid-base imbalance should the nurse assess? (Select all that apply.) a. Positive Chvostek's sign b. Elevated blood pressure c. Bradycardiad. Increased muscle strength e. Anxiety and irritability

ANS: A, E A client receiving total parenteral nutrition is at risk for metabolic alkalosis. Manifestations of metabolic alkalosis include positive Chvostek's sign, normal or low blood pressure, increased heart rate, skeletal muscle weakness, and anxiety and irritability.

The home health nurse cares for an alert and oriented older adult patient with a history of dehydration. Which instructions should the nurse give this patient related to fluid intake? a. "Drink more fluids in the late evening." b. "Increase fluids if your mouth feels dry." c. "More fluids are needed if you feel thirsty." d. "If you feel confused, you need more to drink."

ANS: B An alert older patient will be able to self-assess for signs of oral dryness such as thick oral secretions or dry-appearing mucosa. The thirst mechanism decreases with age and is not an accurate indicator of volume depletion. Many older patients prefer to restrict fluids slightly in the evening to improve sleep quality. The patient will not be likely to notice and act appropriately when changes in level of consciousness occur. :)

A nurse is caring for a client who has the following arterial blood values: pH 7.12, PaO2 56 mm Hg, PaCO2 65 mm Hg, and HCO3- 22 mEq/L. Which clinical situation should the nurse correlate with these values? a. Diabetic ketoacidosis in a person with emphysema b. Bronchial obstruction related to aspiration of a hot dog c. Anxiety-induced hyperventilation in an adolescent d. Diarrhea for 36 hours in an older, frail woman

ANS: B Arterial blood gas values indicate that the client has acidosis with normal levels of bicarbonate, suggesting that the problem is not metabolic. Arterial concentrations of oxygen and carbon dioxide are abnormal, with low oxygen and high carbon dioxide levels. Thus, this client has respiratory acidosis from inadequate gas exchange. The fact that the bicarbonate level is normal indicates that this is an acute respiratory problem rather than a chronic problem, because no renal compensation has occurred.

A patient comes to the clinic complaining of frequent, watery stools for the past 2 days. Which action should the nurse take first? a. Obtain the baseline weight. b. Check the patient's blood pressure. c. Draw blood for serum electrolyte levels. d. Ask about extremity numbness or tingling.

ANS: B Because the patient's history suggests that fluid volume deficit may be a problem, assessment for adequate circulation is the highest priority. The other actions are also appropriate, but are not as essential as determining the patient's perfusion status.

A patient is receiving a 3% saline continuous IV infusion for hyponatremia. Which assessment data will require the most rapid response by the nurse? a. The patient's radial pulse is 105 beats/min. b. There are crackles throughout both lung fields. c. There is sediment and blood in the patient's urine. d. The blood pressure increases from 120/80 to 142/94 mm Hg.

ANS: B Crackles throughout both lungs suggest that the patient may be experiencing pulmonary edema, a life-threatening adverse effect of hypertonic solutions. The increased pulse rate and blood pressure and the appearance of the urine should also be reported, but they are not as dangerous as the presence of fluid in the alveoli.

A patient with multiple draining wounds is admitted for hypovolemia. Which assessment would be the mostaccurate way for the nurse to evaluate fluid balance? a. Skin turgor c. Urine output b. Daily weight d. Edema presence

ANS: B Daily weight is the most easily obtained and accurate means of assessing volume status. Skin turgor varies considerably with age. Considerable excess fluid volume may be present before fluid moves into the interstitial space and causes edema. Urine outputs do not take account of fluid intake or of fluid loss through insensible loss, sweating, or loss from the gastrointestinal tract or wounds.

A nurse is caring for a client who exhibits dehydration-induced confusion. Which intervention should the nurse implement first? a. Measure intake and output every 4 hours. b. Apply oxygen by mask or nasal cannula. c. Increase the IV flow rate to 250 mL/hr. d. Place the client in a high-Fowler's position.

ANS: B Dehydration most frequently leads to poor cerebral perfusion and cerebral hypoxia, causing confusion. Applying oxygen can reduce confusion, even if perfusion is still less than optimal. Increasing the IV flow rate would increase perfusion. However, depending on the degree of dehydration, rehydrating the client too rapidly with IV fluids can lead to cerebral edema. Measuring intake and output and placing the client in a high-Fowler's position will not address the client's problem.

A patient who has a small cell carcinoma of the lung develops syndrome of inappropriate antidiuretic hormone (SIADH). The nurse should notify the health care provider about which assessment finding? a. Serum hematocrit of 42% b. Serum sodium level of 120 mg/dL c. Reported weight gain of 2.2 lb (1 kg) d. Urinary output of 280 mL during past 8 hours

ANS: B Hyponatremia is the most important finding to report. SIADH causes water retention and a decrease in serum sodium level. Hyponatremia can cause confusion and other central nervous system effects. A critically low value likely needs to be treated. At least 30 mL/hr of urine output indicates adequate kidney function. The hematocrit level is normal. Weight gain is expected with SIADH because of water retention.

IV potassium chloride (KCl) 60 mEq is prescribed for treatment of a patient with severe hypokalemia. Which action should the nurse take? a. Administer the KCl as a rapid IV bolus. b. Infuse the KCl at a rate of 10 mEq/hour. c. Only give the KCl through a central venous line. d. Discontinue cardiac monitoring during the infusion.

ANS: B IV KCl is administered at a maximal rate of 10 mEq/hr. Rapid IV infusion of KCl can cause cardiac arrest. KCl can cause inflammation of peripheral veins, but it can be administered by this route. Cardiac monitoring should be continued while patient is receiving potassium because of the risk for dysrhythmias.

A nurse is assessing clients on a medical-surgical unit. Which adult client should the nurse identify as being at greatest risk for insensible water loss?a. Client taking furosemide (Lasix) b. Anxious client who has tachypnea c. Client who is on fluid restrictions d. Client who is constipated with abdominal pain

ANS: B Insensible water loss is water loss through the skin, lungs, and stool. Clients at risk for insensible water loss include those being mechanically ventilated, those with rapid respirations, and those undergoing continuous GI suctioning. Clients who have thyroid crisis, trauma, burns, states of extreme stress, and fever are also at increased risk. The client taking furosemide will have increased fluid loss, but not insensible water loss. The other two clients on a fluid restriction and with constipation are not at risk for fluid loss.

After teaching a client who is being treated for dehydration, a nurse assesses the client's understanding. Which statement indicates the client correctly understood the teaching? a. "I must drink a quart of water or other liquid each day." b. "I will weigh myself each morning before I eat or drink." c. "I will use a salt substitute when making and eating my meals." d. "I will not drink liquids after 6 PM so I won't have to get up at night."

ANS: B One liter of water weighs 1 kg; therefore, a change in body weight is a good measure of excess fluid loss or fluid retention. Weight loss greater than 0.5 lb daily is indicative of excessive fluid loss. The other statements are not indicative of practices that will prevent dehydration.

After teaching a client who was malnourished and is being discharged, a nurse assesses the client's understanding. Which statement indicates the client correctly understood teaching to decrease risk for the development of metabolic acidosis? a. "I will drink at least three glasses of milk each day." b. "I will eat three well-balanced meals and a snack daily." c. "I will not take pain medication and antihistamines together." d. "I will avoid salting my food when cooking or during meals."

ANS: B Starvation or a diet with too few carbohydrates can lead to metabolic acidosis by forcing cells to switch to using fats for fuel and by creating ketoacids as a by-product of excessive fat metabolism. Eating sufficient calories from all food groups helps reduce this risk.

A patient has a parenteral nutrition infusion of 25% dextrose. A student nurse asks the nurse why a peripherally inserted central catheter was inserted. Which response by the nurse is accurate? a. "The prescribed infusion can be given more rapidly when the patient has a central line." b. "The hypertonic solution will be more rapidly diluted when given through a central line." c. "There is a decreased risk for infection when 25% dextrose is infused through a central line." d. "The required blood glucose monitoring is based on samples obtained from a central line."

ANS: B The 25% dextrose solution is hypertonic. Shrinkage of red blood cells can occur when solutions with dextrose concentrations greater than 10% are administered IV. Blood glucose testing is not more accurate when samples are obtained from a central line. The infection risk is higher with a central catheter than with peripheral IV lines. Hypertonic or concentrated IV solutions are not given rapidly.

The nurse is caring for a patient with a massive burn injury and possible hypovolemia. Which assessment data will be of mostconcern to the nurse? a. Urine output is 30 mL/hr. b. Blood pressure is 90/40 mm Hg. c. Oral fluid intake is 100 mL for the past 8 hours. d. There is prolonged skin tenting over the sternum.

ANS: B The blood pressure indicates that the patient may be developing hypovolemic shock as a result of intravascular fluid loss because of the burn injury. This finding will require immediate intervention to prevent the complications associated with systemic hypoperfusion. The poor oral intake, decreased urine output, and skin tenting all indicate the need for increasing the patient's fluid intake but not as urgently as the hypotension.

A nurse evaluates the following arterial blood gas values in a client: pH 7.48, PaO2 98 mm Hg, PaCO2 28 mm Hg, and HCO3- 22 mEq/L. Which client condition should the nurse correlate with these results?a. Diarrhea and vomiting for 36 hours b. Anxiety-induced hyperventilation c. Chronic obstructive pulmonary disease (COPD) d. Diabetic ketoacidosis and emphysema

ANS: B The elevated pH level indicates alkalosis. The bicarbonate level is normal, and so is the oxygen partial pressure. Loss of carbon dioxide is the cause of the alkalosis, which would occur in response to hyperventilation. Diarrhea and vomiting would cause metabolic alterations, COPD would lead to respiratory acidosis, and the client with emphysema most likely would have combined metabolic acidosis on top of a mild, chronic respiratory acidosis.

When assessing a pregnant patient with eclampsia who is receiving IV magnesium sulfate, which finding should the nurse report to the health care provider immediately? a. The bibasilar breath sounds are decreased. b. The patellar and triceps reflexes are absent. c. The patient has been sleeping most of the day. d. The patient reports feeling "sick to my stomach."

ANS: B The loss of the deep tendon reflexes indicates that the patient's magnesium level may be reaching toxic levels. Nausea and lethargy are also side effects associated with magnesium elevation and should be reported, but they are not as significant as the loss of deep tendon reflexes. The decreased breath sounds suggest that the patient needs to cough and deep breathe to prevent atelectasis.

An older adult patient who is malnourished presents to the emergency department with a serum protein level of 5.2 g/dL. The nurse would expect which clinical manifestation? a. Pallor c. Confusion b. Edema d. Restlessness

ANS: B The normal range for total protein is 6.4 to 8.3 g/dL. Low serum protein levels cause a decrease in plasma oncotic pressure and allow fluid to remain in interstitial tissues, causing edema. Confusion, restlessness, and pallor are not associated with low serum protein levels.

A nurse is planning care for a client who is hyperventilating. The client's arterial blood gas values are pH 7.30, PaO2 94 mm Hg, PaCO2 31 mm Hg, and HCO3- 26 mEq/L. Which question should the nurse ask when developing this client's plan of care? a. "Do you take any over-the-counter medications?" b. "You appear anxious. What is causing your distress?" c. "Do you have a history of anxiety attacks?" d. "You are breathing fast. Is this causing you to feel light-headed?

ANS: B The nurse should assist the client who is experiencing anxiety-induced respiratory alkalosis to identify causes of the anxiety. The other questions will not identify the cause of the acid-base imbalance.

A nurse is assessing a client who has acute pancreatitis and is at risk for an acid-base imbalance. For which manifestation of this acid-base imbalance should the nurse assess? a. Agitation b. Kussmaul respirations c. Seizures d. Positive Chvostek's sign

ANS: B The pancreas is a major site of bicarbonate production. Pancreatitis can cause a relative metabolic acidosis through underproduction of bicarbonate ions. Manifestations of acidosis include lethargy and Kussmaul respirations. Agitation, seizures, and a positive Chvostek's sign are manifestations of the electrolyte imbalances that accompany alkalosis.

A patient with new-onset confusion and hyponatremia is being admitted. When making room assignments, the charge nurse should take which action? a. Assign the patient to a semi-private room. b. Assign the patient to a room near the nurse's station. c. Place the patient in a room nearest to the water fountain. d. Place the patient on telemetry to monitor for peaked T waves..

ANS: B The patient should be placed near the nurse's station if confused for the staff to closely monitor the patient. To help improve serum sodium levels, water intake is restricted. Therefore a confused patient should not be placed near a water fountain. Peaked T waves are a sign of hyperkalemia, not hyponatremia. A confused patient could be distracting and disruptive for another patient in a semiprivate room.

A patient who had a transverse colectomy for diverticulosis 18 hours ago has nasogastric suction. The patient complains of anxiety and incisional pain. The patient's respiratory rate is 32 breaths/min, and the arterial blood gases (ABGs) indicate respiratory alkalosis. Which action should the nurse take first? a. Check to make sure the nasogastric tube is patent. b. Give the patient the PRN IV morphine sulfate 4 mg. c. Notify the health care provider about the ABG results. d. Teach the patient how to take slow, deep breaths when anxious.

ANS: B The patient's respiratory alkalosis is caused by the increased respiratory rate associated with pain and anxiety. The nurse's first action should be to medicate the patient for pain. The health care provider may be notified about the ABGs but is likely to instruct the nurse to medicate for pain. The patient will not be able to take slow, deep breaths when experiencing pain. Checking the nasogastric tube can wait until the patient has been medicated for pain.

The nurse is caring for a patient who has a central venous access device (CVAD). Which action by the nurse is appropriate? a. Avoid using friction when cleaning around the CVAD insertion site. b. Use the push-pause method to flush the CVAD after giving medications. c. Obtain an order from the health care provider to change CVAD dressing. d. Position the patient's face toward the CVAD during injection cap changes.

ANS: B The push-pause enhances the removal of debris from the CVAD lumen and decreases the risk for clotting. To decrease infection risk, friction should be used when cleaning the CVAD insertion site. The dressing should be changed whenever it becomes damp, loose, or visibly soiled. A provider's order is not necessary. The patient should turn away from the CVAD during cap changes.

A patient is admitted to the emergency department with severe fatigue and confusion. Laboratory studies are done. Which laboratory value will require the most immediate action by the nurse? a. Arterial blood pH is 7.32. b. Serum calcium is 18 mg/dL. c. Serum potassium is 5.1 mEq/L. d. Arterial oxygen saturation is 91%.

ANS: B The serum calcium is well above the normal level and puts the patient at risk for cardiac dysrhythmias. The nurse should initiate cardiac monitoring and notify the health care provider. The potassium, oxygen saturation, and pH are also abnormal, and the nurse should notify the health care provider about these values as well, but they are not immediately life threatening.

A nurse is caring for a client who has a serum calcium level of 14 mg/dL. Which provider order should the nurse implement first? a. Encourage oral fluid intake. b. Connect the client to a cardiac monitor. c. Assess urinary output. d. Administer oral calcitonin (Calcimar).

ANS: B This client has hypercalcemia. Elevated serum calcium levels can decrease cardiac output and cause cardiac dysrhythmias. Connecting the client to a cardiac monitor is a priority to assess for lethal cardiac changes. Encouraging oral fluids, assessing urine output, and administering calcitonin are treatments for hypercalcemia, but are not the highest priority.

A nurse is caring for a client who is experiencing excessive diarrhea. The client's arterial blood gas values are pH 7.28, PaO2 98 mm Hg, PaCO2 45 mm Hg, and HCO3- 16 mEq/L. Which provider order should the nurse expect to receive? a. Furosemide (Lasix) 40 mg intravenous push b. Sodium bicarbonate 100 mEq diluted in 1 L of D5W c. Mechanical ventilation d. Indwelling urinary catheter

ANS: B This client's arterial blood gas values represent metabolic acidosis related to a loss of bicarbonate ions from diarrhea. The bicarbonate should be replaced to help restore this client's acid-base balance. Furosemide would cause an increase in acid fluid and acid elimination via the urinary tract; although this may improve the client's pH, the client has excessive diarrhea and cannot afford to lose more fluid. Mechanical ventilation is used to treat respiratory acidosis for clients who cannot keep their oxygen saturation at 90%, or who have respirator muscle fatigue. Mechanical ventilation and an indwelling urinary catheter would not be prescribed for this client.

An adult patient who arrived at the triage desk in the emergency department (ED) with minor facial lacerations after a motor vehicle accident has a blood pressure (BP) of 182/94. Which action by the nurse is appropriate? a. Start an IV line to administer antihypertensive medications. b. Recheck the blood pressure after the patient has been assessed. c. Discuss the need for hospital admission to control blood pressure. d. Teach the patient about the stroke risk associated with uncontrolled hypertension.

ANS: B When a patient experiences an acute stressor, the BP increases. The nurse should plan to recheck the BP after the patient has stabilized and received treatment. This will provide a more accurate indication of the patient's usual blood pressure. Elevated BP that occurs in response to acute stress does not increase the risk for health problems such as stroke, indicate a need for hospitalization, or indicate a need for IV antihypertensive medications.

A nurse is planning care for a client who is anxious and irritable. The client's arterial blood gas values are pH 7.30, PaO2 96 mm Hg, PaCO2 43 mm Hg, and HCO3- 19 mEq/L. Which questions should the nurse ask the client and spouse when developing the plan of care?(Select all that apply.) a. "Are you taking any antacid medications?" b. "Is your spouse's current behavior typical?" c. "Do you drink any alcoholic beverages?" d. "Have you been experiencing any vomiting?" e. "Are you experiencing any shortness of breath?"

ANS: B, C This client's symptoms of anxiety and irritability are related to a state of metabolic acidosis. The nurse should ask the client's spouse or family members if the client's behavior is typical for him or her, and establish a baseline for comparison with later assessment findings. The nurse should also assess for alcohol intake because alcohol can change a client's personality and cause metabolic acidosis. The other options are not causes of metabolic acidosis.

A nurse is assessing clients who are at risk for acid-base imbalance. Which clients are correctly paired with the acid-base imbalance? (Select all that apply.) a.Metabolic alkalosis - Young adult who is prescribed intravenous morphine sulfate for pain b.Metabolic acidosis - Older adult who is following a carbohydrate-free diet c.Respiratory alkalosis - Client on mechanical ventilation at a rate of 28 breaths/min d.Respiratory acidosis - Postoperative client who received 6 units of packed red blood cells e.Metabolic alkalosis - Older client prescribed antacids for gastroesophageal reflux disease

ANS: B, C, E Respiratory acidosis often occurs as the result of underventilation. The client who is taking opioids, especially IV opioids, is at risk for respiratory depression and respiratory acidosis. One cause of metabolic acidosis is a strict low-calorie diet or one that is low in carbohydrate content. Such a diet increases the rate of fat catabolism and results in the formation of excessive ketoacids. A ventilator set at a high respiratory rate or tidal volume will cause the client to lose too much carbon dioxide, leading to an acid deficit and respiratory alkalosis. Citrate is a substance used as a preservative in blood products. It is not only a base, it is also a precursor for bicarbonate. Multiple units of packed red blood cells could cause metabolic alkalosis. Sodium bicarbonate antacids may increase the risk of metabolic alkalosis.

A patient who is hospitalized with a pelvic fracture after a motor vehicle accident just received news that the driver of the car died from multiple injuries. What actions should the nurse take based on knowledge of the physiologic stress reactions that may occur in this patient (select all that apply)? a. Assess for bradycardia. b. Observe for decreased appetite. c. Ask about epigastric discomfort. d. Monitor for decreased respiratory rate. e. Check for elevated blood glucose levels.

ANS: B, C, E The physiologic changes associated with the acute stress response can cause changes in appetite, increased gastric acid secretion, and increase blood glucose levels. In addition, stress causes an increase in respiratory and heart rates.

A nurse develops a plan of care for a client who has a history of hypocalcemia. What interventions should the nurse include in this client's care plan? (Select all that apply.) a. Encourage oral fluid intake of at least 2 L/day. b. Use a draw sheet to reposition the client in bed. c. Strain all urine output and assess for urinary stones. d. Provide nonslip footwear for the client to use when out of bed. e. Rotate the client from side to side every 2 hours.

ANS: B, D Clients with long-standing hypocalcemia have brittle bones that may fracture easily. Safety needs are a priority. Nursing staff should use a draw sheet when repositioning the client in bed and have the client wear nonslip footwear when out of bed to prevent fractures and falls. The other interventions would not provide safety for this client.

A nurse assesses a client who is prescribed a medication that inhibits aldosterone secretion and release. For which potential complications should the nurse assess? (Select all that apply.) a. Urine output of 25 mL/hr b. Serum potassium level of 5.4 mEq/L c. Urine specific gravity of 1.02 g/mL d. Serum sodium level of 128 mEq/L e. Blood osmolality of 250 mOsm/L

ANS: B, E Aldosterone is a naturally occurring hormone of the mineralocorticoid type that increases the reabsorption of water and sodium in the kidney at the same time that it promotes excretion of potassium. Any drug or condition that disrupts aldosterone secretion or release increases the client's risk for excessive water loss (increased urine output), increased potassium reabsorption, decreased blood osmolality, and increased urine specific gravity. The client would not be at risk for sodium imbalance.

A nurse cares for a client who has a serum potassium of 7.5 mEq/L and is exhibiting cardiovascular changes. Which prescription should the nurse implement first? a. Prepare to administer sodium polystyrene sulfate (Kayexalate) 15 g by mouth. b. Provide a heart healthy, low-potassium diet. c. Prepare to administer dextrose 20% and 10 units of regular insulin IV push. d. Prepare the client for hemodialysis treatment.

ANS: C A client with a high serum potassium level and cardiac changes should be treated immediately to reduce the extracellular potassium level. Potassium movement into the cells is enhanced by insulin by increasing the activity of sodium-potassium pumps. Insulin will decrease both serum potassium and glucose levels and therefore should be administered with dextrose to prevent hypoglycemia. Kayexalate may be ordered, but this therapy may take hours to reduce potassium levels. Dialysis may also be needed, but this treatment will take much longer to implement and is not the first prescription the nurse should implement. Decreasing potassium intake may help prevent hyperkalemia in the future but will not decrease the client's current potassium level.

A nurse prepares an adult patient with a severe burn injury for a dressing change. The nurse knows that this is a painful procedure and wants to try providing music to help the patient relax. Which action is bestfor the nurse to take? a. Use music composed by Mozart. b. Play music that does not have words. c. Ask the patient about music preferences. d. Select music that has 60 to 80 beats/minute.

ANS: C Although music with 60 to 80 beats/min, music without words, and music composed by Mozart are frequently recommended to reduce stress, each patient responds individually to music and personal preferences are important.

A female patient who initially came to the clinic with incontinence was recently diagnosed with endometrial cancer. She is usually well organized and calm, but the nurse who is giving her preoperative instructions observes that the patient is irritable, has difficulty concentrating, and yells at her husband. Which action should the nurse take? a. Ask the health care provider for a psychiatric referral. b. Focus teaching on preventing postoperative complications. c. Try to calm the patient before repeating any information about the surgery. d. Encourage the patient to combine the hysterectomy with surgery for bladder repair.

ANS: C Because behavioral responses to stress include temporary changes such as irritability, changes in memory, and poor concentration, patient teaching will need to be repeated. It is also important to try to calm the patient by listening to her concerns and fears. Psychiatric referral will not necessarily be needed for her but that can better be evaluated after surgery. Focusing on postoperative care does not address the need for preoperative instruction such as the procedure, NPO instructions before surgery, date and time of surgery, medications to be taken or discontinued before surgery, and so on. The issue of incontinence is not immediately relevant in the discussion of preoperative teaching for her hysterectomy.

The long-term care nurse is evaluating the effectiveness of protein supplements for an older resident who has a low serum total protein level. Which assessment finding indicates that the patient's condition has improved? a. Hematocrit 28% c. Decreased peripheral edema b. Absence of skin tenting d. Blood pressure 110/72 mm Hg

ANS: C Edema is caused by low oncotic pressure in individuals with low serum protein levels. The decrease in edema indicates an improvement in the patient's protein status. Good skin turgor is an indicator of fluid balance, not protein status. A low hematocrit could be caused by poor protein intake. Blood pressure does not provide a useful clinical tool for monitoring protein status.

After providing discharge teaching, a nurse assesses the client's understanding regarding increased risk for metabolic alkalosis. Which statement indicates the client needs additional teaching? a. "I don't drink milk because it gives me gas and diarrhea." b. "I have been taking digoxin every day for the last 15 years." c. "I take sodium bicarbonate after every meal to prevent heartburn." d. "In hot weather, I sweat so much that I drink six glasses of water each day."

ANS: C Excessive oral ingestion of sodium bicarbonate and other bicarbonate-based antacids can cause metabolic alkalosis. Avoiding milk, taking digoxin, and sweating would not lead to increased risk of metabolic alkalosis.

A nurse is assessing a newly admitted patient with chronic heart failure who forgot to take prescribed medications and seems confused. The patient has peripheral edema and shortness of breath. Which assessment should the nurse complete first? a. Skin turgor c. Mental status b. Heart sounds d. Capillary refill

ANS: C Increases in extracellular fluid (ECF) can lead to swelling of cells in the central nervous system, initially causing confusion, which may progress to coma or seizures. Although skin turgor, capillary refill, and heart sounds may also be affected by increases in ECF, these are signs that do not have as immediate impact on patient outcomes as cerebral edema.

After teaching a client to increase dietary potassium intake, a nurse assesses the client's understanding. Which dietary meal selection indicates the client correctly understands the teaching? a. Toasted English muffin with butter and blueberry jam, and tea with sugar b. Two scrambled eggs, a slice of white toast, and a half cup of strawberries c. Sausage, one slice of whole wheat toast, half cup of raisins, and a glass of milk d. Bowl of oatmeal with brown sugar, a half cup of sliced peaches, and coffee

ANS: C Meat, dairy products, and dried fruit have high concentrations of potassium. Eggs, breads, cereals, sugar, and some fruits (berries, peaches) are low in potassium. The menu selection of sausage, toast, raisins, and milk has the greatest number of items with higher potassium content.

A nurse teaches a client who is at risk for mild hypernatremia. Which statement should the nurse include in this client's teaching? a. "Weigh yourself every morning and every night." b. "Check your radial pulse twice a day." c. "Read food labels to determine sodium content." d. "Bake or grill the meat rather than frying it."

ANS: C Most prepackaged foods have a high sodium content. Teaching clients how to read labels and calculate the sodium content of food can help them adhere to prescribed sodium restrictions and can prevent hypernatremia. Daily self-weighing and pulse checking are methods of identifying manifestations of hypernatremia, but they do not prevent it. The addition of substances during cooking, not the method of cooking, increases the sodium content of a meal.

A client at risk for developing hyperkalemia states, "I love fruit and usually eat it every day, but now I can't because of my high potassium level." How should the nurse respond? a. "Potatoes and avocados can be substituted for fruit." b. "If you cook the fruit, the amount of potassium will be lower." c. "Berries, cherries, apples, and peaches are low in potassium." d. "You are correct. Fruit is very high in potassium."

ANS: C Not all fruit is potassium rich. Fruits that are relatively low in potassium and can be included in the diet include apples, apricots, berries, cherries, grapefruit, peaches, and pineapples. Fruits high in potassium include bananas, kiwi, cantaloupe, oranges, and dried fruit. Cooking fruit does not alter its potassium content.

A nurse teaches clients at a community center about risks for dehydration. Which client is at greatest risk for dehydration? a. A 36-year-old who is prescribed long-term steroid therapy b. A 55-year-old receiving hypertonic intravenous fluids c. A 76-year-old who is cognitively impaired d. An 83-year-old with congestive heart failure

ANS: C Older adults, because they have less total body water than younger adults, are at greater risk for development of dehydration. Anyone who is cognitively impaired and cannot obtain fluids independently or cannot make his or her need for fluids known is at high risk for dehydration.

A patient is extremely anxious about having a biopsy on a femoral lymph node. Which relaxation technique would be the bestchoice for the nurse to facilitate during the procedure? a. Yoga stretching c. Relaxation breathing b. Guided imagery d. Mindfulness meditation

ANS: C Relaxation breathing is an easy relaxation technique to teach and use. The patient should remain still during the biopsy and not move or stretch any of his extremities. Meditation and guided imagery require more time to practice and learn.

An older patient receiving iso-osmolar continuous tube feedings develops restlessness, agitation, and weakness. Which laboratory result should the nurse report to the health care provider immediately? a. K+ 3.4 mEq/L (3.4 mmol/L) c. Na+ 154 mEq/L (154 mmol/L) b. Ca+2 7.8 mg/dL (1.95 mmol/L) d. PO4-34.8 mg/dL (1.55 mmol/L)

ANS: C The elevated serum sodium level is consistent with the patient's neurologic symptoms and indicates a need for immediate action to prevent further serious complications such as seizures. The potassium, phosphate, and calcium levels vary slightly from normal but do not require immediate action by the nurse.

Which action should the nurse take firstwhen a patient complains of acute chest pain and dyspnea soon after insertion of a centrally inserted IV catheter? a. Notify the health care provider. b. Offer reassurance to the patient. c. Auscultate the patient's breath sounds. d. Give prescribed PRN morphine sulfate IV.

ANS: C The initial action should be to assess the patient further because the history and symptoms are consistent with several possible complications of central line insertion, including embolism and pneumothorax. The other actions may be appropriate, but further assessment of the patient is needed before notifying the health care provider, offering reassurance, or administration of morphine.

After receiving change-of-shift report, which patient should the nurse assess first? a. Patient with serum potassium level of 5.0 mEq/L who is complaining of abdominal cramping b. Patient with serum sodium level of 145 mEq/L who has a dry mouth and is asking for a glass of water c. Patient with serum magnesium level of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes d. Patient with serum phosphorus level of 4.5 mg/dL who has multiple soft tissue calcium-phosphate precipitates

ANS: C The low magnesium level and neuromuscular irritability suggest that the patient may be at risk for seizures. The other patients have mild electrolyte disturbances or symptoms that require action, but they are not at risk for life-threatening complications.

A patient who has frequent migraines tells the nurse, "My life feels chaotic and out of my control. I could not manage if anything else happens." Which response should the nurse make initially? a. "Regular exercise may get your mind off the pain." b. "Guided imagery can be helpful in regaining control." c. "Tell me more about how your life has been recently." d. "Your previous coping resources can be helpful to you now."

ANS: C The nurse's initial strategy should be further assessment of the stressors in the patient's life. Exercise, guided imagery, or understanding how to use coping strategies that worked in the past may be of assistance to the patient, but more assessment is needed before the nurse can determine this.

The nurse assesses a patient who has been hospitalized for 2 days. The patient has been receiving normal saline IV at 100 mL/hr, has a nasogastric tube to low suction, and is NPO. Which assessment finding would be a priorityfor the nurse to report to the health care provider? a. Oral temperature of 100.1°F b. Serum sodium level of 138 mEq/L (138 mmol/L) c. Gradually decreasing level of consciousness (LOC) d. Weight gain of 2 pounds (1 kg) over the admission weight

ANS: C The patient's history and change in LOC could be indicative of fluid and electrolyte disturbances: extracellular fluid (ECF) excess, ECF deficit, hyponatremia, hypernatremia, hypokalemia, or metabolic alkalosis. Further diagnostic information is needed to determine the cause of the change in LOC and the appropriate interventions. The weight gain, elevated temperature, crackles, and serum sodium level also will be reported but do not indicate a need for rapid action to avoid complications.

During the admission process, the nurse obtains information about a patient through a physical assessment and diagnostic testing. Based on the data shown in the accompanying figure, which nursing diagnosis is appropriate? a. Deficient fluid volume c. Risk for injury: seizures b. Impaired gas exchange d. Risk for impaired skin integrity

ANS: C The patient's muscle cramps and low serum calcium level indicate that the patient is at risk for seizures, tetany, or both. The other diagnoses are not supported by the data because the skin turgor is good. The lungs are clear, arterial blood gases are normal, and there is no evidence of edema or dehydration that might suggest that the patient is at risk for impaired skin integrity.

A hospitalized patient with diabetes tells the nurse, "I don't understand why I can keep my blood sugar under control at home with diet alone, but when I get sick, my blood sugar goes up. This is so frustrating." Which response by the nurse is accurate? a. "The liver is not able to metabolize glucose as well during stressful times." b. "Your diet at the hospital is the most likely cause of the increased glucose." c. "The stress of illness causes release of hormones that increase blood glucose." d. "It is probably coincidental that your blood glucose is higher when you are ill."

ANS: C The release of cortisol, epinephrine, and norepinephrine increase blood glucose levels. The increase in blood glucose is not coincidental. The liver does not control blood glucose. A patient with diabetes who is hospitalized will be on an appropriate diet to help control blood glucose.

After administering 40 mEq of potassium chloride, a nurse evaluates the client's response. Which manifestations indicate that treatment is improving the client's hypokalemia? (Select all that apply.) a. Respiratory rate of 8 breaths/min b. Absent deep tendon reflexes c. Strong productive cough d. Active bowel sounds e. U waves present on the electrocardiogram (ECG)

ANS: C, D A strong, productive cough indicates an increase in muscle strength and improved potassium imbalance. Active bowel sounds also indicate treatment is working. A respiratory rate of 8 breaths/min, absent deep tendon reflexes, and U waves present on the ECG are all manifestations of hypokalemia and do not demonstrate that treatment is working.

A nurse is caring for an older adult client who is admitted with moderate dehydration. Which intervention should the nurse implement to prevent injury while in the hospital? a. Ask family members to speak quietly to keep the client calm. b. Assess urine color, amount, and specific gravity each day. c. Encourage the client to drink at least 1 liter of fluids each shift. d. Dangle the client on the bedside before ambulating.

ANS: D An older adult with moderate dehydration may experience orthostatic hypotension. The client should dangle on the bedside before ambulating. Although dehydration in an older adult may cause confusion, speaking quietly will not help the client remain calm or decrease confusion. Assessing the client's urine may assist with the diagnosis of dehydration but would not prevent injury. Clients are encouraged to drink fluids, but 1 liter of fluid each shift for an older adult may cause respiratory distress and symptoms of fluid overload, especially if the client has heart failure or renal insufficiency.

Spironolactone (Aldactone), an aldosterone antagonist, is prescribed for a patient. Which statement by the patient indicates that the teaching about this medication has been effective? a. "I will try to drink at least 8 glasses of water every day." b. "I will use a salt substitute to decrease my sodium intake." c. "I will increase my intake of potassium-containing foods." d. "I will drink apple juice instead of orange juice for breakfast."

ANS: D Because spironolactone is a potassium-sparing diuretic, patients should be taught to choose low-potassium foods (e.g., apple juice) rather than foods that have higher levels of potassium (e.g., citrus fruits). Because the patient is using spironolactone as a diuretic, the nurse would not encourage the patient to increase fluid intake. Teach patients to avoid salt substitutes, which are high in potassium.

After teaching a client who is prescribed a restricted sodium diet, a nurse assesses the client's understanding. Which food choice for lunch indicates the client correctly understood the teaching? a. Slices of smoked ham with potato salad b. Bowl of tomato soup with a grilled cheese sandwich c. Salami and cheese on whole wheat crackers d. Grilled chicken breast with glazed carrots

ANS: D Clients on restricted sodium diets generally should avoid processed, smoked, and pickled foods and those with sauces and other condiments. Foods lowest in sodium include fish, poultry, and fresh produce. The ham, tomato soup, salami, and crackers are often high in sodium.

An obese female patient who had enjoyed active outdoor activities is stressed because osteoarthritis in her hips now limits her activity. Which action by the nurse will bestassist the patient to cope with this situation? a. Have the patient practice frequent relaxation breathing. b. Ask the patient what outdoor activities she misses the most. c. Teach the patient to use imagery for reducing pain and stress. d. Encourage the patient to consider weight loss to improve symptoms.

ANS: D For problems that can be changed or controlled, problem-focused coping strategies, such as encouraging the patient to lose weight, are most helpful. The other strategies also may assist the patient in coping with her problem, but they will not be as helpful as a problem-focused strategy.

A patient who is taking a potassium-wasting diuretic for treatment of hypertension complains of generalized weakness. Which action is appropriate for the nurse to take? a. Assess for facial muscle spasms. b. Ask the patient about loose stools. c. Recommend the patient avoid drinking orange juice with meals. d. Suggest that the health care provider order a basic metabolic panel.

ANS: D Generalized weakness is a manifestation of hypokalemia. After the health care provider orders the metabolic panel, the nurse should check the potassium level. Facial muscle spasms might occur with hypocalcemia. Orange juice is high in potassium and would be advisable to drink if the patient is hypokalemic. Loose stools are associated with hyperkalemia.

A nurse assesses a client who is prescribed furosemide (Lasix) for hypertension. For which acid-base imbalance should the nurse assess to prevent complications of this therapy? a. Respiratory acidosis b. Respiratory alkalosis c. Metabolic acidosis d. Metabolic alkalosis

ANS: D Many diuretics, especially loop diuretics, increase the excretion of hydrogen ions, leading to excess acid loss through the renal system. This situation is an acid deficit of metabolic origin.

A nurse is evaluating a client who is being treated for dehydration. Which assessment result should the nurse correlate with a therapeutic response to the treatment plan? a. Increased respiratory rate from 12 breaths/min to 22 breaths/min b. Decreased skin turgor on the client's posterior hand and forehead c. Increased urine specific gravity from 1.012 to 1.030 g/mL d. Decreased orthostatic light-headedness and dizziness

ANS: D The focus of management for clients with dehydration is to increase fluid volumes to normal. When fluid volumes return to normal, clients should perfuse the brain more effectively, therefore improving confusion and decreasing orthostatic light-headedness or dizziness. Increased respiratory rate, decreased skin turgor, and increased specific gravity are all manifestations of dehydration.

A middle-aged male patient with usually well-controlled hypertension and diabetes visits the clinic. Today he has a blood pressure of 174/94 mm Hg and a blood glucose level of 190 mg/dL. What patient information may indicate that additional intervention by the nurse is needed? a. The patient states that he takes his prescribed antihypertensive medications daily. b. The patient states that both of his parents have high blood pressure and diabetes. c. The patient indicates that he does blood glucose monitoring several times each day. d. The patient reports that he and his wife are disputing custody of their 8-yr-old son.

ANS: D The increase in blood pressure and glucose levels possibly suggests that stress caused by his divorce and custody battle may be adversely affecting his health. The nurse should assess this further and develop an appropriate plan to assist the patient in decreasing his stress. Although he has been very compliant with his treatment plan in the past, the nurse should assess whether the stress in his life is interfering with his management of his health problems. The family history will not necessarily explain why he has had changes in his blood pressure and glucose levels.

A patient who was involved in a motor vehicle crash has had a tracheostomy placed to allow for continued mechanical ventilation. How should the nurse interpret the following arterial blood gas results: pH 7.48, PaO285 mm Hg, PaCO232 mm Hg, and HCO325 mEq/L? a. Metabolic acidosis c. Respiratory acidosis b. Metabolic alkalosis d. Respiratory alkalosis

ANS: D The pH indicates that the patient has alkalosis and the low PaCO2indicates a respiratory cause. The other responses are incorrect based on the pH and the normal HCO3.

A nurse is caring for a client who is experiencing moderate metabolic alkalosis. Which action should the nurse take? a. Monitor daily hemoglobin and hematocrit values. b. Administer furosemide (Lasix) intravenously. c. Encourage the client to take deep breaths. d. Teach the client fall prevention measures.

ANS: D The priority nursing care for a client who is experiencing moderate metabolic alkalosis is providing client safety. Clients with metabolic alkalosis have muscle weakness and are at risk for falling. The other nursing interventions are not appropriate for metabolic alkalosis.

The nurse notes that a patient who was admitted with diabetic ketoacidosis has rapid, deep respirations. Which action should the nurse take? a. Give the prescribed PRN lorazepam (Ativan). b. Encourage the patient to take deep slow breaths. c. Start the prescribed PRN oxygen at 2 to 4 L/min. d. Administer the prescribed normal saline bolus and insulin.

ANS: D The rapid, deep (Kussmaul) respirations indicate a metabolic acidosis and the need for correction of the acidosis with a saline bolus to prevent hypovolemia followed by insulin administration to allow glucose to reenter the cells. Oxygen therapy is not indicated because there is no indication that the increased respiratory rate is related to hypoxemia. The respiratory pattern is compensatory, and the patient will not be able to slow the respiratory rate. Lorazepam administration will slow the respiratory rate and increase the level of acidosis.

The nurse is caring for a patient who has a calcium level of 12.1 mg/dL. Which nursing action should the nurse include on the care plan? a. Maintain the patient on bed rest. b. Auscultate lung sounds every 4 hours. c. Monitor for Trousseau's and Chvostek's signs. d. Encourage fluid intake up to 4000 mL every day.

ANS: D To decrease the risk for renal calculi, the patient should have a fluid intake of 3000 to 4000 mL daily. Ambulation helps decrease the loss of calcium from bone and is encouraged in patients with hypercalcemia. Trousseau's and Chvostek's signs are monitored when there is a possibility of hypocalcemia. There is no indication that the patient needs frequent assessment of lung sounds, although these would be assessed every shift.
