NUR 112 LAB TEST 2

An unlicensed assistive personnel (UAP) was feeding a client with a tracheostomy. Later that evening, the UAP reports that the client had a coughing spell during the meal. What action by the nurse takes priority? a. Assess the client's lung sounds. b. Assign a different UAP to the client. c. Report the UAP to the manager. d. Request thicker liquids for meals.

ANS: A

The nurse is administering lispro (Humalog) insulin and will keep in mind that this insulin will start to have an effect within which time frame? a. 15 minutes b. 1 to 2 hours c. 80 minutes d. 3 to 5 hours

ANS: A

The nurse is teaching a group of patients about management of diabetes. Which statement about basal dosing is correct? a. "Basal dosing delivers a constant dose of insulin." b. "With basal dosing, you can eat what you want and then give yourself a dose of insulin." c. "Glargine insulin is given as a bolus with meals." d. "Basal-bolus dosing is the traditional method of managing blood glucose levels."

ANS: A

The nurse knows that a subcutaneous injection takes longer to absorb because a. Fewer blood vessels are found under the subcutaneous level. b. Adipose tissue takes longer to metabolize medication. c. Connective tissue holds medication in place longer. d. Some medication leaks out after instillation.

ANS: A

Give it after the meal has been completed. c. Administer it once daily at the time of the midday meal. d. Administer it with a snack before bedtime.

ANS: A

. A school-age child with diabetes gets 30 units of NPH insulin at 0800. According to when this insulin peaks, the child should be at greatest risk for a hypoglycemic episode between when? a. Lunch and dinner b. Breakfast and lunch c. 0830 to his midmorning snack d. Bedtime and breakfast the next morning

ANS: A Intermediate-acting (NPH and Lente) insulins reach the blood 2 to 6 hours after injection. The insulins peak 4 to 14 hours later and stay in the blood for about 14 to 20 hours.

The nurse is discussing with a child and family the various sites used for insulin injections. What site usually has the fastest rate of absorption? a. Arm b. Leg c. Buttock d. Abdomen

ANS: D The abdomen has the fastest rate of absorption but the shortest duration. The arm has a fast rate of absorption but a short duration. The leg has a slow rate of absorption but a long duration. The buttock has the slowest rate of absorption and the longest duration.

A student is practicing suctioning a tracheostomy in the skills laboratory. What action by the student demonstrates that more teaching is needed? a. Applying suction while inserting the catheter b. Preoxygenating the client prior to suctioning c. Suctioning for a total of three times if needed d. Suctioning for only 10 to 15 seconds each time

ANS: A Suction should only be applied while withdrawing the catheter. The other actions are appropriate.

A client has a tracheostomy that is 3 days old. Upon assessment, the nurse notes the client's face is puffy and the eyelids are swollen. What action by the nurse takes priority? a. Assess the client's oxygen saturation. b. Notify the Rapid Response Team. c. Oxygenate the client with a bag-valve-mask. d. Palpate the skin of the upper chest.

ANS: A This client may have subcutaneous emphysema, which is air that leaks into the tissues surrounding the tracheostomy. The nurse should first assess the client's oxygen saturation and other indicators of oxygenation.

A nurse is planning discharge teaching on tracheostomy care for an older client. What factors does the nurse need to assess before teaching this particular client? (Select all that apply.) a. Cognition b. Dexterity c. Hydration d. Range of motion e. Vision

ANS: A, B, D, E The older adult is at risk for having impairments in cognition, dexterity, range of motion, and vision that could limit the ability to perform tracheostomy care and should be assessed. Hydration is not directly related to the ability to perform self-care.

The nurse is preparing a community outreach program for adolescents about the characteristic differences between type 1 and type 2 diabetes mellitus (DM). What concepts should the nurse include? (Select all that apply.) a. Type 1 DM has an abrupt onset. b. Type 1 DM is often controlled with oral glucose agents. c. Type 1 DM occurs primarily in whites. d. Type 2 DM always requires insulin therapy. e. Type 2 DM frequently has a familial history. f. Type 2 DM occurs in people who are overweight.

ANS: A, C, E, F Characteristics of type 1 DM include having an abrupt onset, primarily occurring in whites, and not being controlled with oral glucose agents (insulin is required for therapy). Type 2 DM frequently has a familial history, occurs in people who are overweight, and does not always require insulin therapy (it is used in 20% to 30% of patients).

A nurse is caring for a client who has a tracheostomy tube. What actions may the nurse delegate to unlicensed assistive personnel (UAP)? (Select all that apply.) a. Applying water-soluble lip balm to the client's lips b. Ensuring the humidification provided is adequate c. Performing oral care with alcohol-based mouthwash d. Reminding the client to cough and deep breathe often e. Suctioning excess secretions through the tracheostomy

ANS: A, D The UAP can perform hygiene measures such as applying lip balm and reinforce teaching such as reminding the client to perform coughing and deep-breathing exercises. Oral care can be accomplished with normal saline, not products that dry the mouth. Ensuring the humidity is adequate and suctioning through the tracheostomy are nursing functions.

A client is being discharged home after having a tracheostomy placed. What suggestions does the nurse offer to help the client maintain self-esteem? (Select all that apply.) a. Create a communication system. b. Don't go out in public alone. c. Find hobbies to enjoy at home. d. Try loose-fitting shirts with collars. e. Wear fashionable scarves.

ANS: A, D, E

A client has a tracheostomy tube in place. When the nurse suctions the client, food particles are noted. What action by the nurse is best? a. Elevate the head of the client's bed. b. Measure and compare cuff pressures. c. Place the client on NPO status. d. Request that the client have a swallow study.

ANS: B

A client is scheduled to have a tracheostomy placed in an hour. What action by the nurse is the priority? a. Administer prescribed anxiolytic medication. b. Ensure informed consent is on the chart. c. Reinforce any teaching done previously. d. Start the preoperative antibiotic infusion.

ANS: B Since this is an operative procedure, the client must sign an informed consent, which must be on the chart. Giving anxiolytics and antibiotics and reinforcing teaching may also be required but do not take priority

The nurse is planning home care for a 2-year-old child with a tracheostomy. What recommendation should be included? a. Sterile technique is essential in home care of the tracheostomy. b. Parents are able to change the tracheostomy tube when needed. c. Play activities must be sedentary such as listening to music and working on puzzles. d. The child must wear a plastic bib when eating or drinking to prevent aspiration into the stoma.

ANS: B A plugged, clogged, or obstructed tracheostomy tube is a life-threatening circumstance. Parents are taught the signs and symptoms, how to suction, and how to change the tube. Clean technique and thorough hand washing are sufficient for suctioning, cleaning the tracheostomy site, and changing the tracheostomy tube. The child who is physically able can engage in activities appropriate to age. Young children who may spill food near the stoma should wear a fabric bib without a plastic lining or other device to prevent dribbled food and crumbs from being aspirated

The nurse is caring for a patient with a tracheostomy tube. Which nursing intervention is most effective in promoting effective airway clearance? a. Suctioning respiratory secretions several times every hour b. Administering humidified oxygen through a tracheostomy collar c. Instilling normal saline into the tracheostomy to thin secretions before suctioning d. Deflating the tracheostomy cuff before allowing the patient to cough up secretions

ANS: B Humidification from air humidifiers or humidified oxygen tracheostomy collars can help prevent drying of secretions that cause occlusion. Suctioning should be done only as needed; too frequent suctioning can damage the mucosal lining, resulting in thicker secretions. Normal saline should not be instilled into a tracheostomy; research showed no benefit with this technique. The purpose of the tracheostomy cuff is to keep secretions from entering the lungs; the nurse should not deflate the tracheostomy cuff unless instructed to do so by the health care provider.

The nurse is caring for a child with a tracheostomy. What clinical manifestation should the nurse recognize as an early sign of impending respiratory distress or failure? a. Cyanosis b. Restlessness c. Audible stridor d. Crowing respirations

ANS: B Signs of hypoxemia are initially subtle. Cardinal signs of impending respiratory failure include restlessness, tachypnea, tachycardia, and diaphoresis. Cyanosis is a sign of severe hypoxia. Stridor and crowing respirations are indicative of inflammation. Sternal retractions are an early but less obvious sign.

The nurse is suctioning a patient with a tracheostomy tube. Which action will the nurse take? a. Set suction regulator at 150 to 200 mm Hg. b. Limit the length of suctioning to 10 seconds. c. Apply suction while gently rotating and inserting the catheter. d. Liberally lubricate the end of the suction catheter with a water-soluble solution.

ANS: B Suctioning passes should be limited to 10 seconds to avoid hypoxemia. Suction for a tracheostomy should be set at 100 to 150 mm Hg. Excessive lubrication can clog the catheter or occlude the airway; lubricant is not necessary for oropharyngeal or artificial airway (tracheostomy) suctioning. Suction should never be applied on insertion.

A patient has an order to receive 10 units of U-50 insulin. The nurse is using a U-100 syringe. How many units should the nurse draw up in the syringe and administer? a. 0.2 units b. 2 units c. 5 units d. 20 units

ANS: D The nurse is careful to perform nursing calculations to ensure proper medication administration. U-50 insulin has 50 units of insulin in every milliliter, a U-100 syringe has 100 units in every milliliter. Conversion equals 20 units.

The nurse must suction a 6-month-old infant with a tracheostomy. What intervention should be included? a. Encourage the child to cough to raise the secretions before suctioning. b. Perform each pass of the suction catheter for no longer than 5 seconds. c. Allow the child to rest after every five times the suction catheter is passed. d. Select a catheter with a diameter three quarters of the diameter of the tracheostomy tube.

ANS: B Suctioning should require no longer than 5 seconds per pass. Otherwise, the airway may be occluded for too long. An infant would be unable to cooperate with instructions to cough up secretions. The child is allowed to rest for 30 to 60 seconds after each aspiration to allow oxygen tension to return to normal. Then the process is repeated until the trachea is clear. The catheter should have a diameter one half the size of the tracheostomy tube. If it is too large, it might block the child's airway.

A patient has an order to receive 20 units of U-50 insulin. The nurse is using a U-100 syringe. How many units should the nurse draw up in the syringe and administer? a. 0.04 mL b. 0.4 mL c. 4 mL d. 10 mL

ANS: B The nurse is careful to perform nursing calculations to ensure proper medication administration. U-50 insulin has 50 units of insulin in every milliliter, a U-100 syringe has 100 units in every milliliter. Conversion equals 20 units.

While the nurse is changing the ties on a tracheostomy collar, the patient coughs, dislodging the tracheostomy tube. Which action will the nurse take first? a. Press the emergency response button. b. Insert a spare tracheostomy with the obturator. c. Manually occlude the tracheostomy with sterile gauze. d. Place a face mask delivering 100% oxygen over the nose and mouth.

ANS: B The nurse's first priority is to establish a stable airway by inserting a spare trach into the patient's airway; ideally an obturator should be used. The nurse could activate the emergency response team if the patient is still unstable after the tracheostomy is placed. A patient with a tracheostomy breathes through the tube, not the nose or mouth; a face mask would not be an effective method of getting air into the lungs. Manually occluding pressure over the tracheostomy site is not appropriate and would block the patient's only airway.

The nurse is teaching the parent of a preschool child how to administer the child's insulin injection. The child will be receiving 2 units of regular insulin and 12 units of NPH insulin every morning. What should the parent be taught? a. Draw the insulin in separate syringes. b. Draw the regular insulin first and then the NPH into the same syringe. c. Draw the NPH insulin first and then the regular into the same syringe. d. Check blood sugar first, and if below 120, hold the regular insulin and give the NPH.

ANS: B To obtain maximum benefit from mixing insulins, the recommended practice is to (1) inject the measured amount of air (equivalent to the dosage) into the long-acting insulin; (2) inject the measured amount of air into the rapid-acting (clear) insulin and, without removing the needle; (3) withdraw the clear insulin; and (4) insert the needle (already containing the clear insulin) into the long-acting (cloudy) insulin and then withdraw the desired amount. The blood sugar may be checked before giving the insulin, but the prescribed dose should not be withheld if the blood sugar is 120.

A client with a new tracheostomy is being seen in the oncology clinic. What finding by the nurse best indicates that goals for the nursing diagnosis Impaired Self-Esteem are being met? a. The client demonstrates good understanding of stoma care. b. The client has joined a book club that meets at the library. c. Family members take turns assisting with stoma care. d. Skin around the stoma is intact without signs of infection.

ANS: B The client joining a book club that meets outside the home and requires him or her to go out in public is the best sign that goals for Impaired Self-Esteem are being met.

The nurse is teaching the family of a child with type 1 diabetes about insulin. What should the nurse include in the teaching session? (Select all that apply.) a. Unopened vials are good for 60 days. b. Diabetic supplies should not be left in a hot environment. c. Insulin can be placed in the freezer if not used every day. d. After it has been opened, insulin is good for up to 28 to 30 days. e. Insulin bottles that have been opened should be stored at room temperature or refrigerated.

ANS: B, D, E Insulin bottles that have been "opened" (i.e., the stopper has been punctured) should be stored at room temperature or refrigerated for up to 28 to 30 days. After 1 month, these vials should be discarded. Unopened vials should be refrigerated and are good until the expiration date on the label. Diabetic supplies should not be left in a hot environment. Insulin need not be refrigerated but should be maintained at a temperature between 15° and 29.5° C (59° and 85° F). Freezing renders insulin inactive.

A nurse knows that patient education has been effective when the patient states a. "I must take my parenteral medication with food." b. "If I am 30 minutes late taking my medication, I should skip that dose." c. "I will rotate the location where I give myself injections." d. "Once I start feeling better, I will stop taking my medication."

ANS: C

The nurse needs to administer insulin subcutaneously (subcut) to an obese patient. Which is the proper technique for this injection? a. Using the Z-track method b. Inserting the needle at a 5- to 15-degree angle until resistance is felt c. Pinching the skin at the injection site, and then inserting the needle to below the tissue fold at a 90-degree angle d. Spreading the skin tightly over the injection site, inserting the needle, and then releasing the skin

ANS: C

The nurse needs to administer insulin subcutaneously to an obese patient. Which is the proper technique for this injection? a. Using the Z-track method b. Inserting the needle at a 5- to 15-degree angle until resistance is felt c. Pinching the skin at the injection site, and then inserting the needle to below the tissue fold at a 90-degree angle d. Spreading the skin tightly over the injection site, inserting the needle, and then releasing the skin

ANS: C

When teaching about hypoglycemia, the nurse will make sure that the patient is aware of the early signs of hypoglycemia, including a. hypothermia and seizures. b. nausea and diarrhea. c. confusion and sweating. d. fruity, acetone odor to the breath.

ANS: C

A 3-year-old child with a tracheostomy will soon be discharged. What recommendation should the nurse share with the family? a. Tub baths cannot be given. b. The child cannot be allowed to play outdoors. c. Avoid exposure to noxious fumes such as paint or varnish. d. Cover the tracheostomy with a plastic bib when exposed to cold air.

ANS: C The child with a tracheostomy should not be exposed to noxious fumes such as paint, varnish, or hair spray or to substances such as talc. The parent and child must be cautioned about safety measures around bodies of water. Baths can be taken, but parents must observe the necessary safety precautions. The child may play outdoors with a scarf or other protection that allows air through.

The supervising nurse is observing several different nurses. Which action will cause the supervising nurse to intervene? a. A nurse administers a vaccine without aspirating. b. A nurse gives an IV medication through a 22-gauge IV needle without blood return. c. A nurse draws up the NPH insulin first when mixing a short-acting and intermediate-acting insulin. d. A nurse calls the health care provider for a patient with nasogastric suction and orders for oral meds.

ANS: C The supervising nurse must intervene with the nurse who is drawing up the NPH insulin first; if regular and intermediate-acting (NPH) insulin is ordered, prepare the regular insulin first to prevent the regular insulin from becoming contaminated with the intermediate-acting insulin.

A student nurse is providing tracheostomy care. What action by the student requires intervention by the instructor? a. Holding the device securely when changing ties b. Suctioning the client first if secretions are present c. Tying a square knot at the back of the neck d. Using half-strength peroxide for cleansing

ANS: C To prevent pressure ulcers and for client safety, when ties are used that must be knotted, the knot should be placed at the side of the client's neck, not in back. The other actions are appropriate.

The nurse is teaching a group of patients about self-administration of insulin. What content is important to include? a. Patients need to use the injection site that is the most accessible. b. If two different insulins are ordered, they need to be given in separate injections. c. When mixing insulins, the cloudy (such as NPH) insulin is drawn up into the syringe first. d. When mixing insulins, the clear (such as regular) insulin is drawn up into the syringe first.

ANS: D

The nurse is teaching patients about self-injection of insulin. Which statement is true regarding injection sites? a. Avoid the abdomen because absorption there is irregular. b. Choose a different site at random for each injection. c. Give the injection in the same area each time. d. Rotate sites within the same location for about 1 week before rotating to a new location.

ANS: D

The nurse is teaching the client how to prepare 10 units of regular insulin and 5 units of NPH insulin for injection. The nurse instructs the client to: A. Inject air into the regular insulin and then into the NPH insulin .B Withdraw the regular insulin first C. Inject air into and withdraw the NPH insulin immediately D. Inject air into both vials and withdraw the regular insulin first

ANS: D

The nurse is using a closed suction device. Which patient will be most appropriate for this suctioning method? a. A 5-year-old with excessive drooling from epiglottitis b. A 5-year-old with an asthma attack following severe allergies c. A 24-year-old with a right pneumothorax following a motor vehicle accident d. A 24-year-old with acute respiratory distress syndrome requiring mechanical ventilation

ANS: D

A nurse is assessing a client who has a tracheostomy. The nurse notes that the tracheostomy tube is pulsing with the heartbeat as the client's pulse is being taken. No other abnormal findings are noted. What action by the nurse is most appropriate? a. Call the operating room to inform them of a pending emergency case. b. No action is needed at this time; this is a normal finding in some clients. c. Remove the tracheostomy tube; ventilate the client with a bag-valve-mask. d. Stay with the client and have someone else call the provider immediately.

ANS: D This client may have a trachea-innominate artery fistula, which can be a life-threatening emergency if the artery is breached and the client begins to hemorrhage. Since no bleeding is yet present, the nurse stays with the client and asks someone else to notify the provider.

. The nurse is teaching an adolescent about giving insulin injections. The adolescent asks if the disposable needles and syringes can be used more than once. The nurse's response should be based on which knowledge? a. It is unsafe. b. It is acceptable for up to 24 hours. c. It is acceptable for families with very limited resources. d. It is suitable for up to 3 days if stored in the refrigerator.

ANS: D Bacterial counts are unaffected if insulin syringes are handled in an aseptic manner and stored in the refrigerator between use. The syringes can be used up to 3 days and result in a considerable cost savings. Bacterial counts remain low for up to 72 hours with proper technique. The family's resources are not an issue; if a practice is unsafe, the family should not be encouraged to endanger the child by reusing equipment.

The supervising nurse is watching nurses prepare medications. Which action by one of the nurses will the supervising nurse stop immediately? a. Rolls insulin vial between hands b. Administers a dose of correction insulin c. Draws up glargine (Lantus) in a syringe by itself d. Prepares NPH insulin to be given intravenously (IV)

ANS: D The only insulin that can be given IV is regular. NPH cannot be given IV and must be stopped. All the rest demonstrate correct practice. Insulin is supposed to be rolled, not shaken. Glargine is supposed to be given by itself; it cannot be mixed with another medication. Correction insulin, also known as sliding-scale insulin, provides a dose of insulin based on the patient's blood glucose level. The term correction insulin is preferred because it indicates that small doses of rapid- or short-acting insulins are needed to correct a patient's elevated blood sugar.
