The nurse educator is presenting a lecture on the respiratory and cardiovascular systems. Which response given by the nursing staff would indicate to the educator that they have an understanding of cardiac output?

"If the client's stroke volume is 50 mL and heart rate is 50 beats per minute, then the cardiac output is 2.5 L/minute."

A nurse is performing CPR on a client who collapsed. Which guidelines should be used for this procedure? Select all that apply.

- Postion client supine - Use head tilt chin lift maneuver to open airway - Rest elbows on the flat surface under the client, grasp the angle of the client's lower jaw, and lift with both hands

The nurse is teaching a healthy adult client about adequate hydration. How much average daily intake does the nurse recommend?

2,500 mL/day

The nurse is preparing to administer a large-volume enema to an adult client. How far should the nurse insert the tubing into the rectum?

3 inches (7.5 cm)

A physician has asked the nurse to use microdrip tubing to administer a prescribed dosage of IV solution to a client. What is the standard drop factor of microdrip tubing?

60 drops/mL

Which client would be a candidate for total parenteral nutrition?

A client with colitis and bloody diarrhea

The nurse is replacing a client's ileostomy appliance and has identified that the diameter of the stoma is 3.5 cm. The nurse has trimmed the flange of the new appliance to a diameter of 7 cm. What will be the most likely outcome of the nurse's action?

A risk that the peristomal skin will become excoriated Rationale: An appliance that is too large will expose peristomal skin to digestive enzymes, leading to skin breakdown. It will not fit as securely as it should, but this does not necessarily mean that it will need to be changed daily. Prolapse is not related to the way that the appliance is sized or trimmed.

A nurse assessing a client's respiratory effort notes that the client's breaths are shallow and 8 per minute. Shortly after, the client's respirations cease. Which form of oxygen delivery should the nurse use for this client?

Ambu bag Rationale: If the client is not breathing with an adequate rate and depth, or if the client has lost the respiratory drive, a manual resuscitation bag (Ambu bag) may be used to deliver oxygen until the client is resuscitated or can be intubated with an endotracheal tube. Oxygen masks may cover only the nose and mouth and can vary in the amount of oxygen delivered. A nasal oxygen cannula is a device that consists of a plastic tube that fits behind the ears, and a set of two prongs that are placed in the nostril. An oxygen tent is a tentlike enclosure within which the air supply can be enriched with oxygen to aid a client's breathing. Oxygen masks, nasal cannula, and oxygen tents are used for clients who have a respiratory drive.

A client with closed-angle glaucoma and a cough has a prescription for a cough medicine. The nurse would question which cough medicine if prescribed for this client?

Any cough medicine that contains an anti-histamine Rationale: The client with closed-angle glaucoma should avoid cough medicine because of its anticholinergic action. The client with diabetes should avoid cough medicine with a high sugar content. The client with thyroid disorders should avoid cough medicine containing iodine. The client with hypertension should avoid cough medicine with decongestants.

The nurse is monitoring fluid intake and output (I&O) for a client who has diarrhea. What will the nurse document as input on the record? Select all that apply.

Any liquids (no solid foods)

A client is admitted to the hospital with shortness of breath, cyanosis and an oxygen saturation of 82% (0.82) on room air. Which action should the nurse implement first?

Apply oxygen as prescribed

The nurse is planning to discontinue a peripherally inserted central catheter (PICC) for a client who is prescribed warfarin therapy. Which intervention will individualize care for this client?

Apply pressure to insertion site for at least 3 minutes

The nurse is caring for a client who has a compromised cardiopulmonary system and needs to assess the client's tissue oxygenation. The nurse would use which appropriate method to assess this client's oxygenation?

Arterial blood gas Rationale: Arterial blood gases include the levels of oxygen, carbon dioxide, bicarbonate, and pH. Blood gases determine the adequacy of alveolar gas exchange and the ability of the lungs and kidneys to maintain the acid-base balance of body fluids.

A client 57 years of age is recovering in a hospital following a bilateral mastectomy and breast reconstruction 2 days earlier. Since her surgery, the client has been unwilling to mobilize despite the nurse's education on the benefits of early mobilization following surgery. The nurse would recognize that the client's prolonged immobility creates a risk for:

Atelectasis Rationale: Prolonged bed rest can result in the incomplete lung expansion and collapse of alveoli that characterize atelectasis. Immobility is not commonly implicated in cases of pneumothorax or hemothorax. A pneumothorax is a collapsed lung. Hemothorax is a collection of blood in the space between the chest wall and the lung. Tachypnea, if present, would likely be a sign of atelectasis rather than an independent finding.

A nurse is reading a journal article about pollutants and their effect on an individual's respiratory function. Which problem would the nurse most likely identify as an effect of exposure to automobile pollutants?

Bronchitis

A client is diagnosed with metabolic acidosis. The nurse develops a plan of care for this client based on the understanding that the body compensates for this condition by:

By increasing ventilation through the lungs Rationale: The body compensates for the metabolic acidosis by increasing ventilation through the lungs, thus increasing the rate of carbonic acid excretion, resulting in a fall in PaCO2. To compensate for respiratory alkalosis, the kidneys increase the excretion of HCO3− to the urine. Kidneys compensate for respiratory acidosis by increasing the excretion of H+ ion into the urine. The kidneys respond to metabolic alkalosis by retaining acid and excreting HCO3−.

The nurse is caring for a client who had a parathyroidectomy. Upon evaluation of the client's laboratory studies, the nurse would expect to see imbalances in which electrolytes related to the removal of the parathyroid gland?

Calcium and phosphorus Rationale: The parathyroid gland secretes parathyroid hormone, which regulates the level of calcium and phosphorus. Removal of the parathyroid gland will cause calcium and phosphorus imbalances. Sodium, chloride, and potassium are regulated by the kidneys and affected by fluid balance.

The nurse is preparing to irrigate a Foley catheter. What is the nurse's initial action?

Check electronic health record for medical order.

Which is a common anion?

Chloride

A nurse is caring for a client who is on total parenteral nutrition (TPN). Which clients are candidates for TPN? Select all that apply.

Clients with: - Liver or renal failure - Clients with major burns - Clients with inflammatory bowel disease

The nurse is informed while receiving a nursing report that the client has been hypoxic during the evening shift. Which assessment finding is consistent with hypoxia?

Confusion

A client has edema of the feet and ankles, along with crackles in the lower lobes and a frothy, productive cough. The client is suffering from:

Congestive heart failure

A client admitted with heart failure requires careful monitoring of his fluid status. Which method will provide the nurse with the best indication of the client's fluid status?

Daily weight Rationale: Due to the possible numerous sources of inaccuracies in fluid intake and output measurement, the record of a client's daily weight may be the more accurate measurement of a client's fluid status. Laboratory tests are helpful in assessing kidney function and electrolyte values, but do not provide the precise information on fluid losses or gains as is provided by a daily weight (at the same time, using the same scale). Output measurements are not meaningful without intake measurements.

A client is taking a diuretic such as furosemide. When implementing client education, what information should be included?

Decreased potassium levels Rationale: Many diuretics such as furosemide are potassium wasting; hence, potassium levels are measured to detect hypokalemia.

An older adult client visits a health care facility for a scheduled physical assessment. During the assessment, the client reports difficulty breathing. Which suggestion could the nurse make to improve the client's respiratory function?

Drink liberal amounts of water Rationale: The nurse could suggest liberal fluid intake for the client in order to improve respiratory function. Older adults need encouragement to maintain liberal fluid intake, which keeps the mucous membranes moist. Unless contraindicated, the nurse should encourage the client to engage in regular exercise to maintain optimal respiratory function. A nasal strip reduces airflow resistance by widening the nasal breathing passageway, thus promoting easier breathing. An older adult may or may not use a nasal strip to improve respiratory function. The nurse should advise older adults to receive annual influenza immunizations and a pneumonia immunization after 65 years of age or earlier if there is a history of chronic illness.

A nurse is caring for a client recovering from abdominal surgery who is experiencing paralytic ileus. The client has a nasogastric tube connected to suction. How often should the nurse irrigate this tube?

Every 4-8 hours

After surgery, a client is on IV therapy for the next 4 days. How often should the nurse change the IV tubing for this client?

Every 72 hours Rationale: IV tubings are generally changed every 72 hours or as per the facility's policy. Solutions are replaced when they finish infusing or every 24 hours, whichever occurs first. IV tubings are not replaced after every solution is over or after every 12, 24, or 36 hours.

The nurse is implementing an order for oxygen for a client with facial burns. Which delivery device will the nurse gather?

Face tent

A nurse is changing a client's peripheral venous access dressing. The nurse finds that the site is bleeding and oozing. Which type of dressing should the nurse use for this client?

Gauze dressing

The process of filtration begins at the:

Glomerulus

An older adult client is visibly pale with a respiratory rate of 30 breaths per minute. Upon questioning, the client states to the nurse, "I can't seem to catch my breath." The nurse has responded by repositioning the client and measuring the client's oxygen saturation using pulse oximetry, yielding a reading of 90%. The nurse should interpret this oxygen saturation reading in light of the client's:

Hemoglobin Rationale: Pulse oximetry readings are reflective of the number of available oxygen receptors on hemoglobin molecules. Consequently, an acceptable reading in a client with low hemoglobin can be artificially inflated. Age, blood pH, and electrolyte levels do not have a direct bearing on the accuracy and clinical application of pulse oximetry.

During a blood transfusion, a client displays signs of immediate onset facial flushing, hypotension, tachycardia, and chills. Which transfusion reaction should the nurse suspect?

Hemolytic transfusion reaction: incompatibility of blood product Rationale: The listed symptoms occur when a blood product is incompatible. Hives, itching, and anaphylaxis occur in allergic reactions; fever, chills, headache, and malaise occur in febrile reactions. In a bacterial reaction, fever; hypertension; dry, flushed skin; and abdominal pain occur.

To drain the apical sections of the upper lobes of the lungs, the nurse should place the client in which position?

High fowlers position

A client needs an intravenous fluid that will pull fluids into the vascular space. What type of fluid does the nurse prepare to administer as prescribed?

Hypertonic

A client who is admitted to the health care facility has been diagnosed with cerebral edema. Which intravenous solution needs to be administered to this client?

Hypertonic Rationale: Hypertonic solutions are used in extreme cases when it is necessary to reduce cerebral edema or to expand the circulatory volume rapidly because it is more concentrated than body fluid and draws cellular and interstitial water into the intravascular compartment. Hypotonic solutions are administered to clients with fluid losses in excess of fluid intake, such as those who have diarrhea or vomiting. Isotonic solution is generally administered to maintain fluid balance in clients who may not be able to eat or drink for a short period. Colloid solutions are used to replace circulating blood volume because the suspended molecules pull fluid from other compartments. However, these solutions are not related to clients with cerebral edema.

A nurse is reviewing the client's serum electrolyte levels which are as follows:Sodium: 138 mEq/L (138 mmol/L)Potassium: 3.2 mEq/L (3.2 mmol/L)Calcium: 10.0 mg/dL (2.5 mmol/L)Magnesium: 2.0 mEq/L (1.0 mmol/L)Chloride: 100 mEq/L (100 mmol/L)Phosphate: 4.5 mg/dL (2.6 mEq/L)Based on these levels, the nurse would identify which imbalance?

Hypokalemia

A client with protracted nausea and vomiting has been receiving intravenous solution at 125 ml/h for the past several hours. The administration of this solution has resulted in an increase in blood pressure because the water in the solution has passed through the semipermeable membrane of blood cells, causing them to swell. What type of solution has the client been receiving?

Hypotonic solution

A nursing student is teaching a healthy adult client about adequate hydration. Which statement by the client indicates understanding of adequate hydration?

I should drink 2,500 mL a day

Which nursing interventions would be appropriate for a client diagnosed with deficient fluid volume? Select all that apply.

IV therapy, nutrition management and electrolyte management Rationale: If a client is at a fluid volume deficit, intravenous therapy may be ordered by the primary care provider to replenish fluids and electrolytes, warranting fluid and electrolyte management. Nutrition management may help to increase and maintain electrolyte levels by adding foods high in certain electrolytes to the diet. Hypervolemia refers to fluid volume excess. Fluid restriction would be contraindicated because the client is already at a deficit. Edema would be monitored in the case of fluid volume excess.

When providing chemotherapeutic agents, which catheter is accessed with a non-coring needle?

Implanted venous access catheter

A nurse is preparing an education plan for a client with heart failure who is experiencing edema. As part of the plan, the nurse wants to describe the underlying mechanism for why the edema develops. Which mechanism will nurse likely address?

Increased hydrostatic pressure Rationale: The edema that occurs with heart failure is caused by decreased cardiac output with a back-up of blood resulting from increased hydrostatic pressure. Decreased colloid oncotic pressure is the mechanism responsible for edema of malnutrition, liver failure, and nephrosis. Lymph node blockage is the mechanism responsible for edema associated with a mastectomy or lymphoma. Increased capillary permeability is the mechanism responsible for edema associated with allergies, septic shock and pulmonary edema.

The nurse is assessing the vital signs of clients in a community health care facility. Which client respiratory results should the nurse report to the health care provider?

Infant with respiratory rate of 16bpm Rationale: The infant's normal respiratory rate is 20 to 40 breaths per minute. The normal range for a child age 1 to 5 years is 20 to 32 breaths per minute. For a child 6 to 12 years of age the normal respiratory rate is 18 to 26 breaths per minute. The normal respiratory rate for an adult 65 years and older is 16 to 24 breaths per minute.

A health care provider orders the collection of a sputum specimen from a client with a suspected bacterial infection. Which action best ensures a usable specimen?

Instruct the client to inhale deeply and then cough.

The nurse, along with a nursing student, is caring for Mrs. Roper, who was admitted with dehydration. The student asks the nurse where most of the body fluid is located. The nurse should answer with which fluid compartment?

Intracellular

Which solution is a crystalloid solution that has the same osmotic pressure as that found within the cells of the body and is used to expand the intravascular volume?

Isotonic

When the nurse reviews the client's laboratory reports revealing sodium, 140 mEq/L (140 mmol/L); potassium, 4.1 mEq/L (4.1 mmol/L); calcium 7.9 mg/dL (1.975 mmol/L), and magnesium 1.9 mg/dL (0.781 mmol/L); the nurse should notify the physician of the client's:

Low calcium Rationale: Normal total serum calcium levels range between 8.9 and 10.1 mg/dL (2.225 to 2.525 mmol/L).

A nurse is caring for a female client who is unable to transfer to a commode. The nurse is assisting the client with positioning on a bedpan. Which statement should guide the nurse's action?

Many clients find it embarrassing or degrading to use a bedpan.

A young man has developed gastric esophageal reflux disease. He is treating it with antacids. Which acid-base imbalance is he at risk for developing?

Metabolic alkalosis Rationale: Endocrine disorders and ingestion of large amounts of antacids cause metabolic alkalosis.

A nurse is obtaining an arterial blood specimen from a client to assess acid-base status. Which value is expected for a client with normal status?

Normal values include: HCO3: 22 to 26 mEq/L; pH: 7.35 to 7.45; PaCO2: 35; and SaO2: oxygen saturation greater than 95%.

The nurse is caring for a client whose blood type is B negative. Which donor blood type does the nurse confirm as compatible for this client?

O negative

While examining a client, the nurse palpates the client's chest and back. What would the nurse expect to identify with this technique?

Pattern of thoracic expansion Rationale: The nurse can assess patterns of thoracic expansion through palpation. Fluid-filled and consolidated portions of lungs can be assessed through percussion, not through palpation. Presence of pleural rub can be assessed through auscultation.

The nurse observes that the client's pulse oximetry is 89%. What is the priority nursing action?

Perform respiratory assessment Rationale: As the nurse enters the room, the respiratory assessment immediately begins by visualizing the client's skin color, observing chest symmetry, vocalization, and auditory adventitious lung sounds. The nurse can then proceed to check the placement of the pulse oximeter, report findings to the health care provider, and document.

A client sustained severe trauma in a motor vehicle accident and has had 26 units of packed red blood cells infused since admission 2 days previously. What does the nurse predict will be prescribed to replace the clotting factors lost with the infusion of large amounts of packed red blood cells?

Plasma

A client's primary care provider has informed the nurse that the client will require thoracentesis. The nurse should suspect that the client has developed which disorder of lung function?

Pleural effusion Rationale: Thoracentesis involves the removal of fluid from the pleural space, either for diagnostic purposes or to remove an accumulation of fluid in this space (pleural effusion). Tachypnea and wheezes are not symptoms that directly indicate a need for thoracentesis. Pneumonia would necessitate the procedure only if the infection resulted in pleural effusion.

When a nurse observes that an older client's skin is dry and shiny and his nails are thickened, the nurse determines that the client is most likely experiencing

Poor tissue perfusion

A 50-year-old client with hypertension is being treated with a diuretic. The client reports muscle weakness and falls easily. The nurse should assess which electrolyte?

Potassium

The nurse is performing a check with an oxygen analyzer. Which oxygen analyzer assessment finding indicates that the device is working properly?

Reads 0.21 when checking oxygen in room air

The nurse is caring for a client who has a prescription for a peripheral intravenous (IV) infusion of a liter of 0.9 sodium chloride solution over 10 hours by gravity infusion. The drop factor is 60 gtts/mL. After reviewing the image, what is best action by the nurse to provide the appropriate drops per minute of medication?

Regulate flow to allow 25 gtts every 15 seconds

A client vomits as a nurse is inserting his oropharyngeal airway. What would be the mostappropriate intervention in this situation?

Remove the airway, turn the client to the side, and provide mouth suction, if necessary

The nurse is describing the role of antidiuretic hormone in the regulation of body fluids. What phenomenon takes place when antidiuretic hormone is present?

Renal system retains more water Rationale: When antidiuretic hormone is present, the distal tubule of the nephron becomes more permeable to water. This causes the renal system to retain more water. A lack of antidiuretic hormone causes increased production of dilute urine. Antidiuretic hormone does not cause thirst.

When caring for a client who is on intravenous therapy, the nurse observes that the client has developed redness, warmth, and discomfort along the vein. Which intervention should the nurse perform for this complication?

Restart infusion in another vein and apply warm compress Rationale: Prolonged use of the same vein can cause phlebitis; the nurse should apply a warm compress after restarting the IV. The nurse need not elevate the client's head, position the client on the left side, or apply antiseptic and a dressing. The client's head is elevated if the client exhibits symptoms of circulatory overload. The client is positioned on the left side if exhibiting signs of air embolism. The nurse applies antiseptic and a dressing to an IV site in the event of an infection.

A health care provider has prescribed oxygen to be delivered at 8 L/minute for a client who does not have a tracheostomy. Which oxygen delivery device(s) will the nurse consider using? Select all that apply.

Simple mask and partial rebreather mask

The nurse is performing an assessment for an older adult client admitted with dehydration. When assessing the skin turgor of this client, which area of the body will be best for the nurse to assess?

Sternum

When inspecting a client's chest to assess respiratory status, the nurse should be aware of which normal finding?

The chest should be slightly convex with no sternal depression

A nurse takes a client's pulse oximetry reading and finds that it is normal. What does this finding indicate?

The client available hemoglobin is adequately saturated with oxygen.

The nurse is preparing a packed red blood cell transfusion for a client. The nurse checks the client's blood type in the electronic medical record (EMR) and notes that it is blood type B. What does this mean?

The client has anti-A antibodies

The nurse is assessing a client with an older arteriovenous (AV) graft for hemodialysis access in the left arm. The client reports significant pain to the distal left arm. Capillary refill in the left hand is greater than 4 seconds. Which should the nurse assess before contacting the health care provider?

Thrill and bruit

The nurse is assessing a client's intravenous line and notes small air bubbles within the tubing. What is the priority nursing action?

Tighten roller clamp to stop infusion

A nurse suctioning a client through a tracheostomy tube should be careful not to occlude the Y-port when inserting the suction catheter because it would cause what condition to occur?

Trauma to the tracheal mucosa

T/F: After insertion of a chest tube, fluctuations in the water-seal chamber that correspond with inspiration and expiration are an expected and normal finding.

True Rationale: After insertion of a chest tube, fluctuations in the water-seal chamber that correspond with inspiration and expiration are an expected and normal finding. A nurse caring for a client with a chest tube should monitor the patient's respiratory status and vital signs, check the dressing, and maintain the patency and integrity of the drainage system.

During data collection, the nurse auscultates low-pitched, soft sounds over the lungs' peripheral fields. Which appropriate terminology would the nurse use to describe these lung sounds when documenting?

Vesicular breath sounds Rationale: Vesicular breath sounds are normal and described as low-pitched, soft sounds over the lungs' peripheral fields. Crackles are soft, high-pitched, discontinuous popping sounds heard on inspiration. Medium-pitched blowing sounds heard over the major bronchi describe bronchovesicular breath sounds. Bronchial breath sounds are loud, high-pitched sounds heard over the trachea and larynx.

A nurse needs to get an accurate fluid output assessment of a client with severe diarrhea. Which action should the nurse perform?

Weigh the clients wet linen/dressing

The nurse auscultates the lungs of a client with asthma who reports shortness of breath, sore throat, and congestion. Which finding does the nurse expect to document?

Wheezing

Which guideline describes the proper method for measuring the appropriate length to use when inserting a nasopharyngeal airway?

When holding the airway on the side of the client's face, it should reach from the tragus of the ear to the tip of the nostril. Rationale: The nasopharyngeal airway length is measured by holding the airway on the side of the client's face. The airway should reach from the tragus of the ear to the tip of the nostril. The diameter should be slightly smaller than the diameter of the nostril. For an oropharyngeal airway, when holding the airway on the side of the client's face, it should reach from the opening of the mouth to the back angle of the jaw.

An infant is brought to the emergency room with dehydration due to vomiting. After several failed attempts to start an IV, the nurse observes a scalp vein. When accessing the scalp vein, the nurse should use:

Winged infusion needle
