Nurs 215( Med Surg 1)

ANS: C The nurse should note irregular patterns of bruising, especially in the shapes of hands or fingers, in different stages of resolution. These may be indications of other health problems or abuse and should be further investigated. It is important that the nurse interview the patient alone because, if mistreatment is occurring, the patient may not disclose it in the presence of the person who may be the abuser. Throw rugs and shoes with slippery surfaces may contribute to falls. Radiographs may be needed if the patient has fallen recently and reports pain or decreased mobility. However, the nurse's first nursing action is to further assess the patient's safety.

. The home health nurse notices irregular patterns of bruising at different stages of healing on an older patient's body. Which action should the nurse take first? a. Ensure the patient wears shoes with nonslip soles. b. Discourage using throw rugs throughout the house. c. Talk with the patient alone and ask about the bruising. d. Suggest that the health care provider prescribe radiographs

ANS: D A recommended bundle at insertion of a central line is hand hygiene prior to catheter insertion; use of maximum sterile barrier precautions upon insertion; chlorhexidine skin antisepsis prior to insertion and during dressing changes; avoidance of the femoral vein for central venous access for adults; and daily evaluation of line necessity, with prompt removal of non-essential lines. Povidone-iodine is not recommended

.A nurse is assisting the health care provider in inserting a central line. Which action indicates the nurse is following the recommended bundle protocol to reduce central line-associated bloodstream infections (CLABSI)? a. Preps skin with povidone-iodine solution. b. Suggests the femoral vein for insertion site. c. Applies double gloving without hand hygiene. d. Uses chlorhexidine skin antisepsis prior to insertion.

ANS: D The steps for inserting an intravenous catheter are as follows: Apply tourniquet; select vein; release tourniquet; clean site; reapply tourniquet; insert vascular access device; and advance and secure.

.A nurse is preparing to start peripheral intravenous (IV) therapy. In which order will the nurse perform the steps starting with the first one? 1. Clean site. 2. Select vein. 3. Apply tourniquet. 4. Release tourniquet. 5. Reapply tourniquet. 6. Advance and secure. 7. Insert vascular access device. a. 1, 3, 2, 7, 5, 4, 6 b. 1, 3, 2, 5, 7, 6, 4 c. 3, 2, 1, 5, 7, 6, 4 d. 3, 2, 4, 1, 5, 7, 6

ANS: C An incisional biopsy would remove the entire mole and the tissue borders. The appearance of the mole indicates that it may be cancerous. A shave biopsy would not remove the entire mole. The mole is too large to be removed with punch biopsy. Excisional biopsies are done for smaller lesions and where a good cosmetic effect is desired, such as on the face.

.A patient in the dermatology clinic is scheduled for removal of a 15-mm multicolored and irregular mole from the upper back. The nurse should prepare the patient for which type of biopsy? a. Shave biopsy b. Punch biopsy c. Incisional biopsy d. Excisional biopsy

ANS: B The description of the lesions indicates that they are grouped in a bilateral distribution. The other terms are inconsistent with the description of the lesions.

.During assessment of the patient's skin, the nurse observes a similar pattern of discrete, small, raised lesions on the left and right upper back areas. Which term should the nurse use to document the distribution of these lesions? a. Confluent b. Symmetric c. Zosteriform d. Generalized

ANS: B Physical examination findings of deficit include postural hypotension, tachycardia, thready pulse, dry mucous membranes, and poor skin turgor. Pitting edema indicates that the patient may be retaining excess extracellular fluid.

A nurse is assessing a patient. Which assessment finding should cause a nurse to further assess for extracellular fluid volume deficit? a. Moist mucous membranes b. Postural hypotension c. Supple skin turgor d. Pitting edema

ANS: B A contrast medium containing iodine is injected into the subarachnoid space during a myelogram. The patient's allergy would contraindicate the use of this medium. The health care provider may need to provide orders to treat back pain after the procedure. Clear liquids are usually considered safe up to 4 hours before a diagnostic or surgical procedure. The patient's anxiety should be addressed, but procedural plans would not need to be changed.

A 39-yr-old patient with a suspected herniated intervertebral disc is scheduled for a myelogram. Which information communicated by the nurse to the health care provider before the procedure would change the procedural plans? a. The patient is anxious about the test results. b. The patient reports a previous allergy to shellfish. c. The patient has back pain when lying flat for more than 4 hours. d. The patient drank apple juice 4 hours before the scheduled procedure.

ANS: A It is important to note whether the patient takes any -adrenergic blockers because this classification of medications is also used to treat glaucoma, and there may be an increase in adverse effects. The use of aspirin does not increase intraocular pressure and is safe for patients with glaucoma. Although older patients should have yearly eye examinations, treatment will not be affected by the 10-year gap in eye care. Conjunctivitis does not increase the risk for glaucoma.

A 65-yr-old patient is being evaluated for glaucoma. Which information given by the patient has implications for the patient's treatment plan? a. "I take metoprolol (Lopressor) for angina." b. "I take aspirin when I have a sinus headache." c. "I have had frequent episodes of conjunctivitis." d. "I have not had an eye examination for 10 years."

ANS: B The nurse's initial action should be further assessment of the patient's concerns and visual problems. The other actions may be appropriate, depending on what the nurse finds with further assessment.

A 75-yr-old patient who lives alone at home tells the nurse, "I am afraid of losing my independence because my eyes don't work as well they used to." Which action should the nurse take first? a. Discuss the increased risk for falls that is associated with impaired vision. b. Ask the patient about what type of vision problems are being experienced. c. Explain that there are many ways to compensate for decreases in visual acuity. d. Suggest ways of improving the patient's safety, such as using brighter lighting.

ANS: D A rapid gain in weight usually indicates extracellular volume (ECV) excess if the person began with normal ECV. Asking the patient about urination habits will help determine whether the body is trying to excrete the excess fluid or if renal dysfunction is contributing to ECV excess. This is too rapid a weight gain to be dietary; it is fluid retention. Asking about following a weight loss program will not help determine the cause of the problem. Caloric intake does not account for rapid weight changes. Dry mouth and thirst accompany ECV deficit, which would be associated with rapid weight loss.

A chemotherapy patient has gained 5 pounds in 2 days. Which assessment question by the nurse is most appropriate? a. "Are you following any weight loss program?" b. "How many calories a day do you consume?" c. "Do you have dry mouth or feel thirsty?" d. "How many times a day do you urinate?"

ANS: A,C, D Decreased temperature and swelling at the insertion site are manifestions of IV infiltration. Stop the infusion and start a new line in the other extremity. Apply a warm or cold compress for a client who is experiencing manifestations fo an IV infiltraion, depending on the solution. Elevate the arm of a client who is experienceing edema with an infiltration.

A nurse assessing the IV catheter insertion site for a client receiving a nonvesicant solution and notes swelling at the site with decreased skin temperature. Which of the following actions should the nurse take? (select all that apply.) A. Stop the infusion. B. Start a new IV access distal to this site. C. Apply warm compresses to the insertion site. D. Elevate the client's arm. E. Obtain a specimen for a culture at the insertion site.

ANS: B 250 mL ÷ 50 mL/hr = 5 hr 1845 + 5 hr = 2345, which would be 2345 on Monday.

A nurse begins infusing a 250-mL bag of IV fluid at 1845 on Monday and programs the pump to infuse at 50 mL/hr. At what time should the infusion be completed? a. 2300 Monday b. 2345 Monday c. 0015 Tuesday d. 0045 Tuesday

ANS: B Potatoes and fruits are high in potassium. Milk and cheese are high in calcium. Canned soups and vegetables are high in sodium. Whole grains and dark green leafy vegetables are high in magnesium.

A nurse is administering a diuretic to a patient and teaching the patient about foods to increase. Which food choices by the patient will best indicate successful teaching? a. Milk and cheese b. Potatoes and fresh fruit c. Canned soups and vegetables d. Whole grains and dark green leafy vegetables

ANS: A The signs and symptoms are concurrent with fluid volume overload. Anaphylactic shock would have presented with urticaria, dyspnea, and hypotension. Septicemia would include a fever. A hemolytic reaction would consist of flank pain, chills, and fever.

A nurse is assessing a patient who is receiving a blood transfusion and finds that the patient is anxiously fidgeting in bed. The patient is afebrile and dyspneic. The nurse auscultates crackles in both lung bases and sees jugular vein distention. On which transfusion complication will the nurse focus interventions? a. Fluid volume overload b. Hemolytic reaction c. Anaphylactic shock d. Septicemia

ANS: C Total parenteral nutrition is an intravenous solution composed of nutrients and electrolytes to replace the ones the patient is not eating or losing. TPN does not stimulate the appetite. TPN does not contain blood pressure medication or antibiotics

A nurse is caring for a cancer patient who presents with anorexia, blood pressure 100/60, and elevated white blood cell count. Which primary purpose for starting total parenteral nutrition (TPN) will the nurse add to the care plan? a. Stimulate the patient's appetite to eat. b. Deliver antibiotics to fight off infection. c. Replace fluid, electrolytes, and nutrients. d. Provide medication to raise blood pressure.

ANS: B. According to the evidence-based practice the nurse should first withdraw the solution from the IV access. This reduces the amount of vesicant in the body and lowers the risk of tissue damange.

A nurse is caring for a client experinencing IV extravasation. The facility requires the administraition of a antidote for the prescribed IV solution. After stopping the IV infusion, which of the following actions should the nurse take first? A. Remove the IV catheter. B. Withdraw the solution from the IV access. C. Administer the antidote to the vesicant. D. Insert a new IV access in a different extremity.

ANS: A The total fluid intake and output equals 700 mL, which meets the provider goals. Patients with nasogastric suctioning are at risk for potassium deficit, so the nurse would anticipate a potassium supplement to correct this condition. Remember to record half the volume of ice chips when calculating intake. The other measures would be unnecessary because the net fluid volume is equal.

A nurse is caring for a diabetic patient with a bowel obstruction and has orders to ensure that the volume of intake matches the output. In the past 4 hours, the patient received dextrose 5% with 0.9% sodium chloride through a 22-gauge catheter infusing at 150 mL/hr and has eaten 200 mL of ice chips. The patient also has an NG suction tube set to low continuous suction that had 300-mL output. The patient has voided 400 mL of urine. After reporting these values to the health care provider, which order does the nurse anticipate? a. Add a potassium supplement to replace loss from output. b. Decrease the rate of intravenous fluids to 100 mL/hr. c. Administer a diuretic to prevent fluid volume excess. d. Discontinue the nasogastric suctioning

ANS: D The IV site has phlebitis. The nurse should discontinue the IV. The phlebitis score is 3. The site has phlebitis, not infiltration. A moist compress may be needed after the IV is discontinued.

A nurse is caring for a patient who is receiving peripheral intravenous (IV) therapy. When the nurse is flushing the patient's peripheral IV, the patient reports pain. Upon assessment, the nurse notices a red streak that is warm to the touch. What is the nurse's initial action? a. Record a phlebitis grade of 4. b. Assign an infiltration grade. c. Apply moist compress. d. Discontinue the IV.

ANS: A A nursing assistive personnel (NAP) can record intake and output. An RN cannot delegate regulating flow rate, starting an IV, or changing an IV dressing to an NAP.

A nurse is caring for a patient with peripheral intravenous (IV) therapy. Which task will the nurse assign to the nursing assistive personnel? a. Recording intake and output b. Regulating intravenous flow rate c. Starting peripheral intravenous therapy d. Changing a peripheral intravenous dressing

ANS: B, E, F The nurse should stop the infusion before removing the IV catheter, so the fluid does not drip on the patient's skin; keep the catheter parallel to the skin while removing it to reduce trauma to the vein; and apply pressure to the site for 2 to 3 minutes after removal to decrease bleeding from the site. Scissors should not be used because they may accidentally cut the catheter or tubing or may injure the patient. During removal of the IV catheter, light pressure, not firm pressure, is indicated to prevent trauma. Clean gloves are used for discontinuing a peripheral IV access because gloved hands will handle the external dressing, tubing, and tape, which are not sterile.

A nurse is discontinuing a patient's peripheral IV access. Which actions should the nurse take? (Select all that apply.) a. Wear sterile gloves and a mask. b. Stop the infusion before removing the IV catheter. c. Use scissors to remove the IV site dressing and tape. d. Apply firm pressure with sterile gauze during removal. e. Keep the catheter parallel to the skin while removing it. f. Apply pressure to the site for 2 to 3 minutes after removal.

ANS: C Distend the veins using a blood pressure cuff to reduce overfilling of the vein, which can result in a hematoma.

A nurse is preparing to initiate IV therapy for an older adult client. Which of the following actions should the nurse plan to take? A. Use a disposable razor to remove excess hair on the extremity. B. Select the back of the client's hand to insert the IV catheter. C. Distend the veins by using a blood pressure cuff. D. Direct the client to raise their arm above the heart.

ANS: C When administering a transfusion you need an appropriate-size IV catheter and blood administration tubing that has a special in-line filter. The patient's blood should not be mixed with the infusion blood. Air bubbles should not be allowed to enter the blood. The only substance compatible with blood is normal saline; no additives should be mixed with the infusing blood.

A nurse is preparing to start a blood transfusion. Which type of tubing will the nurse obtain? a. Two-way valves to allow the patient's blood to mix and warm the blood transfusing b. An injection port to mix additional electrolytes into the blood c. A filter to ensure that clots do not enter the patient d. An air vent to let bubbles into the blood

ANS: A, C, F The vein should be relatively straight to avoid catheter occlusion. Contraindications to starting an IV catheter are conditions such as mastectomy, AV fistula, and central line in the extremity and should be checked before initiation of IV. Avoid areas of flexion if possible. The nurse should start distally and move proximally, choosing the nondominant arm if possible. The nurse should feel for the best location; a good vein should feel spongy, a rigid vein should be avoided because it might have had previous trauma or damage.

A nurse is selecting a site to insert an intravenous (IV) catheter on an adult. Which actions will the nurse take? (Select all that apply.) a. Check for contraindications to the extremity. b. Start proximally and move distally on the arm. c. Choose a vein with minimal curvature. d. Choose the patient's dominant arm. e. Select a vein that is rigid. f. Avoid areas of flexion.

ANS: 460 The patient's fluid intake is 250 mL of feeding, 60 mL of water (30 mL before and after), and 150 blood: . Fluid intake includes all liquids that a person eats (e.g., gelatin, ice cream, soup), drinks (e.g., water, coffee, juice), or receives through nasogastric or jejunostomy feeding tubes. IV fluids (continuous infusions and intermittent IV piggybacks) and blood components also are sources of intake. Fluid output includes urine, diarrhea, vomitus, gastric suction, and drainage from postsurgical wounds or other tubes.

A patient has 250 mL of a jejunostomy feeding with 30 mL of water before and after feeding and 200 mL of urine. Thirty minutes later the patient has 100 mL of diarrhea. At 1300 the patient receives 150 mL of blood and voids another 200 mL. Calculate the patient's intake. Record your answer as a whole number. _____ mL

ANS: A Because functions of the cerebellum include coordination and balance, the patient with dysfunction is at risk for falls. The cerebellum does not affect memory, mood, or swallowing ability.

A patient has a tumor in the cerebellum. What goal should the nurse use to focus the plan of care? a. Prevent falls. b. Stabilize mood. c. Avoid aspiration. d. Improve memory.

ANS: D The nurse should first attach new tubing and begin running in normal saline at a rate to keep the vein open, in case any medications need to be delivered through an IV site. The existing tubing should not be used because that would infuse the blood in the tubing into the patient. It is necessary to preserve the IV catheter in place for IV access to treat the patient. After the patient has been assessed and stabilized, the blood can be returned to the blood bank.

A patient has an acute intravascular hemolytic reaction to a blood transfusion. After discontinuing the blood transfusion, which is the nurse's next action? a. Discontinue the IV catheter. b. Return the blood to the blood bank. c. Run normal saline through the existing tubing. d. Start normal saline at TKO rate using new tubing.

ANS: A Intracellular (inside the cells) fluid accounts for approximately two thirds of total body water. Extracellular (outside the cells) is approximately one third of the total body water. Intravascular fluid (liquid portion of the blood) and transcellular fluid are two major divisions of the extracellular compartment.

A patient has dehydration. While planning care, the nurse considers that the majority of the patient's total water volume exists in with compartment? a. Intracellular b. Extracellular c. Intravascular d. Transcellular

ANS: C The patient's sensation that a curtain is coming across the field of vision suggests retinal detachment and the need for rapid action to prevent blindness. The other findings would be expected with the patient's history of being hit in the eye

A patient in the emergency department reports being struck in the right eye with a fist. Which finding is a priority for the nurse to communicate to the health care provider? a. The patient reports a right-sided headache. b. The sclera on the right eye has broken blood vessels. c. The patient reports "a curtain" over part of the visual field. d. The area around the right eye is bruised and tender to the touch.

ANS: C Microdrip tubing delivers 60 drops/mL. Calculation for a rate of 125 mL/hr using microdrip tubing: (125 mL/1 hr)(60 drops/1 mL)(1 hr/60 min) = 125 drop/min.

A patient is to receive 1000 mL of 0.9% sodium chloride intravenously at a rate of 125 mL/hr. The nurse is using microdrip gravity drip tubing. Which rate will the nurse calculate for the minute flow rate (drops/min)? a. 12 drops/min b. 24 drops/min c. 125 drops/min d. 150 drops/min

ANS: C Patients with prolonged vomiting and diarrhea become hypovolemic. A solution to replace extracellular volume is 0.9% sodium chloride, which is an isotonic solution. 0.225% and 0.45% sodium chloride are hypotonic. 3% sodium chloride is hypertonic.

A patient presents to the emergency department with reports of vomiting and diarrhea for the past 48 hours. The health care provider orders isotonic intravenous (IV) therapy. Which IV will the nurse prepare? a. 0.225% sodium chloride (1/4 NS) b. 0.45% sodium chloride (1/2 NS) c. 0.9% sodium chloride (NS) d. 3% sodium chloride (3% NaCl)

ANS: C Vision may not be restored for up to 1 year after corneal transplant. Because the patient is not experiencing complications of the surgery, an emergency clinic visit is not needed. Because "floaters" are not associated with complications of corneal transplant, the nurse will not need to ask the patient about their presence. Corticosteroid drops, not mydriatic drops, are used after corneal transplant surgery

A patient who received a corneal transplant 2 weeks ago calls the ophthalmology clinic to report that his vision has not improved with the transplant. Which action should the nurse take? a. Suggest the patient arrange a ride to the clinic immediately. b. Ask about the presence of "floaters" in the patient's visual field. c. Remind the patient it may take months to restore vision after transplant. d. Teach the patient to continue using prescribed pupil-dilating medications.

ANS: B Lichenification is likely to occur in areas where the patient scratches the skin often. It results in thickening of the skin with accentuated normal skin markings. Vitiligo is the complete absence of melanin in the skin. Keloids are hypertrophied scars. Yellowish-brown skin indicates jaundice. Vitiligo, keloids, and jaundice do not usually occur because of scratching the skin

A patient who reports chronic itching of the ankles continuously scratches the area. Which assessment finding should the nurse expect? a. Hypertrophied scars on both ankles b. Thickening of the skin around the ankles c. Yellowish-brown skin around both ankles d. Complete absence of melanin in both ankles

ANS: A The loss of stereoscopic vision created by the eye patch impairs the patient's ability to see in three dimensions and to judge distances. This increases the risk for falls. There is no evidence in the assessment data for inability to care for home, disturbed body image, or difficulty coping.

A patient who underwent eye surgery must wear an eye patch until the scheduled postoperative clinic visit. Which patient problem will the nurse address in the plan of care? a. Risk for falls b. Difficulty coping c. Disturbed body image d. Inability to care for home

ANS: C The priority action for a patient after a head injury is to assess and maintain airway and breathing. Because the patient is reporting shortness of breath, it is essential that the nurse assess the oxygen saturation. The other actions are also appropriate but are not the first action the nurse will take.

A patient with a head injury after a motorcycle crash arrives in the emergency department (ED) reporting shortness of breath and severe eye pain. Which action will the nurse take first? a. Assess cranial nerve functions. b. Administer the prescribed analgesic. c. Check the patient's oxygen saturation. d. Examine the eye for evidence of trauma.

ANS: C Following pneumatic retinopexy, the patient will need to position the head so the air bubble remains in contact with the retinal tear. Dark lenses and bilateral eye patches are not required after this procedure. Saturation of any eye dressings would not be expected following this procedure.

A patient with a right retinal detachment had a pneumatic retinopexy procedure. Which information will the nurse include in the discharge teaching plan? a. The use of eye patches to reduce movement of the operative eye b. The need to wear dark glasses to protect the eyes from bright light c. The purpose of maintaining the head resting in a prescribed position d. The procedure for dressing changes when the eye dressing is saturated

ANS: D The photosensitizing drug used for photodynamic therapy is activated by exposure to bright light and can cause burns in areas exposed to light for 5 days after the treatment. There are no restrictions on the use of facial lotions, medications to keep the pupils dilated would not be appropriate, and bright lights would increase the risk for damage caused by the treatment.

A patient with age-related macular degeneration (AMD) has just had photodynamic therapy. Which statement by the patient indicates that the discharge teaching has been effective? a. "I will use drops to keep my pupils dilated until my appointment." b. "I will need to use brighter lights to read for at least the next week." c. "I will not use facial lotions near my eyes during the recovery period." d. "I will cover up with long-sleeved shirts and pants for the next 5 days."

ANS: C Cyanosis persons with dark skin is more easily seen in the mucous membranes. Earlobe color may change in persons with light skin, but this change in skin color is hard to detect on darker skin. Application of pressure to the palms of the hands and nail bed assessment would check for adequate circulation but not for skin color

A patient with dark skin has been admitted to the hospital with acute decompensated heart failure. How would the nurse assess this patient for cyanosis? a. Assess the skin color of the earlobes. b. Apply pressure to the palms of the hands. c. Check the lips and oral mucous membranes. d. Examine capillary refill time of the nail beds.

ANS: B Patients should be taught that eye discomfort and visual blurring are expected side effects of the ophthalmic drops but that the drops must be used to prevent further visual-field loss. The temporary burning and visual blurriness might not lessen with ongoing use and do not indicate a need for a dosage or medication change.

A patient with glaucoma who has been using timolol (Timoptic) drops for several days tells the nurse that the eyedrops cause eye burning and visual blurriness after administration. The best response to the patient's statement is a. "Those symptoms may indicate a need for a change in dosage of the eyedrops." b. "The drops are uncomfortable, but it is important to use them to retain your vision." c. "These are normal side effects of the drug, which should be less noticeable with time." d. "Notify your health care provider so that different eyedrops can be prescribed for you."

ANS: D For a lumbar puncture, the patient lies in the lateral recumbent position. The procedure does not usually require a sedative, is done in the patient room, and has no risk for aspiration

A patient with suspected meningitis is scheduled for a lumbar puncture. What action should the nurse take before the procedure? a. Enforce NPO status for 4 hours. b. Transfer the patient to radiology. c. Administer a sedative medication. d. Help the patient to a lateral position.

ANS: B After a head injury, the patient may be experiencing intracranial bleeding and increased intracranial pressure. Herniation of the brain could result if lumbar puncture is performed. The other orders are appropriate

An unconscious male patient has just arrived in the emergency department with a head injury caused by a motorcycle crash. Which planned intervention by the health care provider should the nurse question? a. Obtain x-rays of the skull and spine. b. Prepare the patient for lumbar puncture. c. Send for computed tomography (CT) scan. d. Perform neurologic checks every 15 minutes.

ANS: A When documenting visual acuity, the first number indicates the standard (for normal vision) of 20 feet and the second number indicates the line that the patient is able to read when standing 20 feet from the Snellen chart. OS is the abbreviation for left eye, and OD is the abbreviation for right eye. The remaining three answers do not correctly describe the patient's visual acuity

Assessment of a patient's visual acuity reveals that the left eye can see at 20 feet what a person with normal vision can see at 50 feet and the right eye can see at 20 feet what a person with normal vision can see at 40 feet. Which finding should the nurse record? a. OS 20/50; OD 20/40 b. OU 20/40; OS 50/20 c. OD 20/40; OS 20/50 d. OU 40/20; OD 50/20

ANS: C Expressive speech (ability to express the self in language) is controlled by Broca's area in the frontal lobe. The temporal lobe contains Wernicke's area, which is responsible for receptive speech (ability to understand language input). The cerebellum and brainstem do not affect higher cognitive functions such as speech.

During the neurologic assessment, the patient is unable to respond verbally to the nurse but cooperates with the nurse's directions to move his hands and feet. What should the nurse suspect as a likely cause of these findings? a. Cerebellar injury b. A brainstem lesion c. Frontal lobe damage d. A temporal lobe lesion

ANS: A The infant should be seen first. An infant's proportion of total body water (70% to 80% total body weight) is greater than that of children or adults. Infants and young children have greater water needs and immature kidneys. They are at greater risk for extracellular volume deficit and hypernatremia because body water loss is proportionately greater per kilogram of weight. A teenager with excessive edema from a sprained ankle can wait. A middle-aged adult moaning in pain can wait as can an older adult with a blood pressure of 112/60.

Four patients arrive at the emergency department at the same time. Which patient will the nurse see first? a. An infant with temperature of 102.2° F and diarrhea for 3 days b. A teenager with a sprained ankle and excessive edema c. A middle-aged adult with abdominal pain who is moaning and holding her stomach d. An older adult with nausea and vomiting for 3 days with blood pressure 112/60

ANS: C The trigeminal and facial nerves are responsible for the corneal reflex. The optic nerve is tested by having the patient read a Snellen chart or a newspaper. Assessment of pupil response to light and ptosis are used to evaluate function of the oculomotor nerve.

How should the nurse assess the patient's trigeminal and facial nerve function (CNs V and VII)? a. Check for unilateral eyelid droop. b. Shine a light into the patient's pupil. c. Touch a cotton wisp strand to the cornea. d. Have the patient read a magazine or book.

ANS: B POAG develops slowly and without symptoms except for a gradual loss of visual fields. Acute closed-angle glaucoma may present with excruciating pain, colored halos, and blurred vision. Problems with depth perception are not associated with POAG.

How should the nurse evaluate a patient for improvement after treatment of primary open-angle glaucoma (POAG)? a. Question the patient about blurred vision. b. Note any changes in the patient's visual field. c. Ask the patient to rate the pain using a 0 to 10 scale. d. Assess the patient's depth perception when climbing stairs.

ANS: D The patient's increased intraocular pressure indicates glaucoma, which decreases peripheral vision. Because central visual acuity is unchanged by glaucoma, assessment of visual acuity could be normal even if the patient has worsening glaucoma. Color perception and pupil reaction to light are not affected by glaucoma.

In reviewing a patient's medical record, the nurse notes that the last eye examination revealed an intraocular pressure of 28 mm Hg. What should the nurse plan to assess? a. Visual acuity b. Pupil reaction c. Color perception d. Peripheral vision

ANS: B Because cerebral angiograms require insertion of a catheter into the femoral artery, bleeding is a possible complication. The nurse will need to check the pulse and blood pressure and assess the catheter insertion site in the groin as soon as the patient arrives. Carotid duplex studies and EEG are noninvasive. The nurse will need to assist with the lumbar puncture as soon as possible but monitoring for hemorrhage after cerebral angiogram has a higher priority.

Several patients have been hospitalized for diagnosis of neurologic problems. Which patient should the nurse assess first? a. A patient with a transient ischemic attack (TIA) returning from carotid duplex studies b. A patient with a brain tumor who has just arrived on the unit after a cerebral angiogram c. A patient with a seizure disorder who has just completed an electroencephalogram (EEG) d. A patient prepared for a lumbar puncture whose health care provider is waiting for assistance

ANS: C When performing a sensory assessment, the nurse should not provide verbal clues. The other actions by the new nurse are appropriate.

The charge nurse is observing a new nurse who is assessing a patient with a traumatic spinal cord injury for sensation. Which action by the new nurse indicates the need for further teaching about neurologic assessment? a. Tests for light touch before testing for pain. b. Has the patient close the eyes during testing. c. Asks the patient if the instrument feels sharp. d. Uses an irregular pattern to test for intact touch.

ANS: B Because coughing will increase intraocular pressure, patients are generally taught to avoid coughing during the acute postoperative time. The other actions are appropriate for a patient after having this surgery.

The charge nurse observes a newly hired nurse performing all the following interventions for a patient who has just undergone right cataract removal and an intraocular lens implant. Which action requires that the charge nurse intervene? a. The nurse leaves the eye shield in place. b. The nurse encourages the patient to cough. c. The nurse elevates the patient's head to 45 degrees. d. The nurse applies corticosteroid drops to the right eye.

ANS: C An effective measure of fluid retention or loss is daily weights; each kilogram (2.2 pounds) change is equivalent to 1 liter of fluid gained or lost. This measurement should be performed at the same time every day using the same scale and the same amount of clothing. Although intake and output records are important assessment measures, some patients are not able to keep their own records themselves. Blood pressure can decrease with extracellular volume (ECV) deficit but will not necessarily increase with recent ECV excess (heart failure patient). Edema occurs with ECV excess but not with clinical dehydration.

The health care provider asks the nurse to monitor the fluid volume status of a heart failure patient and a patient at risk for clinical dehydration. Which is the most effective nursing intervention for monitoring both of these patients? a. Assess the patients for edema in extremities. b. Ask the patients to record their intake and output. c. Weigh the patients every morning before breakfast. d. Measure the patients' blood pressures every 4 hours.

ANS: A 0.45% sodium chloride is a hypotonic solution. NS and LR are isotonic. D5LR is hypertonic.

The health care provider has ordered a hypotonic intravenous (IV) solution to be administered. Which IV bag will the nurse prepare? a. 0.45% sodium chloride (1/2 NS) b. 0.9% sodium chloride (NS) c. Lactated Ringer's (LR) d. Dextrose 5% in Lactated Ringer's (D5LR)

ANS: A Hypertonic solutions will move fluid from the intracellular to the extracellular (intravascular). A hypertonic solution has a concentration greater than normal body fluids, so water will shift out of cells because of the osmotic pull of the extra particles. Movement of water from the extracellular (intravascular) into cells (intracellular) occurs when hypotonic fluids are administered. Distribution of fluid between intravascular and interstitial spaces occurs by filtration, the net sum of hydrostatic and osmotic pressures

The nurse administers an intravenous (IV) hypertonic solution to a patient. In which direction will the fluid shift? a. From intracellular to extracellular b. From extracellular to intracellular c. From intravascular to intracellular d. From intravascular to interstitial

ANS: B If the lesion is caused by intradermal or subcutaneous bleeding or a nonvascular cause, the discoloration will remain when direct pressure is applied to the lesion. If the lesion is caused by blood vessel dilation, blanching will occur with direct pressure. The other assessments will assess circulation to the leg but will not be helpful in determining the etiology of the lesion

The nurse assesses a circular, flat, reddened lesion about 5 cm in diameter on a middle-aged patient's ankle. How should the nurse determine if the lesion is related to intradermal bleeding? a. Elevate the patient's leg. b. Press firmly on the lesion. c. Check the temperature of the skin around the lesion. d. Palpate the dorsalis pedis and posterior tibial pulses.

ANS: D Postoperative cataract surgery patients usually experience little or no pain, so pain at a level 5 on a 10-point pain scale may indicate complications such as hemorrhage, infection, or increased intraocular pressure. The other information given by the patient indicates a need for patient teaching or follow-up does not indicate that complications of the surgery may be occurring.

The nurse at the eye clinic made a follow-up telephone call to a patient who underwent cataract extraction and intraocular lens implantation the previous day. Which information is the priority to communicate to the health care provider? a. The patient reports that the vision has not improved. b. The patient requests a prescription refill for next week. c. The patient feels uncomfortable wearing an eye patch. d. The patient reports eye pain rated 5 (on a 0 to 10 scale).

ANS: C Mydriatic medications used for pupil dilation are sympathetic nervous system stimulants and may increase heart rate and blood pressure. Using punctal occlusion when administering the mydriatic and monitoring of blood pressure are indicated for this patient. Blurred vision is an expected finding with cataracts. Patients are expected to be NPO before the surgical procedure. Cataract extraction and intraocular lens implantation are done using local anesthesia.

The nurse at the outpatient surgery unit obtains the following information about a patient who is scheduled for cataract extraction and implantation of an intraocular lens. Which information is important to report to the health care provider before the procedure? a. The patient has had blurred vision for 3 years. b. The patient has not eaten anything for 8 hours. c. The patient takes antihypertensive medications. d. The patient gets nauseated with general anesthesia

ANS: D Although "floaters" are usually caused by vitreous liquefaction and are common in aging patients, they can be caused by hemorrhage into the vitreous humor or by retinal tears, so the nurse's first action will be to examine the retina and posterior chamber. Although the ophthalmologist will examine the patient, the presence of spots or floaters in a 65-year-old patient is not an emergency. The spots may indicate retinal damage, but the nurse should assess the eye further before discussing this with the patient

The nurse in the eye clinic is examining a 67-yr-old patient who says, "I see small spots that move around in front of my eyes." Which action will the nurse take first? a. Immediately have the ophthalmologist evaluate the patient. b. Explain that spots and "floaters" are a normal part of aging. c. Warn the patient that these spots may indicate retinal damage. d. Use an ophthalmoscope to examine the posterior eye chambers.

ANS: A The Jaeger card is used to assess near vision problems and presbyopia in persons older than 40 years of age. The card should be held 14 inches away from eyes while the patient reads words in various print sizes. Using a penlight to determine pupil change is testing pupil response. A short burst of air may be used to test intraocular pressure but is not used for testing presbyopia. Covering one eye at a time while reading a wall chart at 20 feet describes the Snellen test.

The nurse is assessing a 65-yr-old patient for presbyopia. Which instruction will the nurse give the patient before the test? a. "Hold this card and read the print out loud." b. "Cover one eye while reading the wall chart." c. "You'll feel a short burst of air directed at your eyeball." d. "A light will be used to look for a change in your pupils."

ANS: C The patient is in fluid overload. Raising the head of the bed to ease breathing is the first action. Offering calcium-rich foods is for hypocalcemia, not fluid overload. Administering a diuretic is the second action. Increasing fluids is contraindicated and would make the situation worse.

The nurse is assessing a patient and finds crackles in the lung bases and neck vein distention. Which action will the nurse take first? a. Offer calcium-rich foods. b. Administer diuretic. c. Raise head of bed. d. Increase fluids

ANS: A Intake = 150 mL of orange juice, 60 mL of ice chips (but only counts as 30 since ice chips are half of the amount), and 75 mL of chicken broth; 150 + 30 + 75 = 255. Output = 125 mL of urine (void) and 250 mL of vomitus; 125 + 250 = 375.

The nurse is calculating intake and output on a patient. The patient drinks 150 mL of orange juice at breakfast, voids 125 mL after breakfast, vomits 250 mL of greenish fluid, sucks on 60 mL of ice chips, and for lunch consumes 75 mL of chicken broth. Which totals for intake and output will the nurse document in the patient's medical record? a. Intake 255; output 375 b. Intake 285; output 375 c. Intake 505; output 125 d. Intake 535; output 125

ANS: A The nurse will see the patient with D5W and blood to prevent a medication error. When preparing to administer blood, prime the tubing with 0.9% sodium chloride (normal saline) to prevent hemolysis or breakdown of RBCs. All the rest are normal. A patient with type A blood can receive type O. Type O is considered the universal donor. A patient with a mastectomy should have the IV in the other arm. Potassium chloride should be diluted, and it is never given IV push.

The nurse is caring for a group of patients. Which patient will the nurse see first? a. A patient with D5W hanging with the blood b. A patient with type A blood receiving type O blood c. A patient with intravenous potassium chloride that is diluted d. A patient with a right mastectomy and an intravenous site in the left arm

ANS: B Patients with AIC have a high risk for concurrent genital Chlamydia infection and should be referred for sexually transmitted infection testing. AIC is treated with antibiotics. Antiviral and corticosteroid medications are not appropriate therapies. Although some types of Chlamydia infection do cause blindness, AIC does not lead to blindness, so referral for visual rehabilitation is not appropriate.

The nurse is caring for a patient diagnosed with adult inclusion conjunctivitis (AIC) caused by C. trachomatis. Which action should be included in the plan of care? a. Applying topical corticosteroids to decrease inflammation b. Discussing the need for sexually transmitted infection testing c. Educating about the use of antiviral eyedrops to treat the infection d. Assisting with applying for community visual rehabilitation services

ANS: D, E A patient who has worked as a landscaper is at risk for skin lesions caused by sun exposure such as erythema and actinic keratosis. Vitiligo, alopecia, and intertrigo are not associated with excessive sun exposure.

The nurse is developing a health promotion plan for an older adult who worked in the landscaping business for 40 years. The nurse will plan to teach the patient about how to self-assess for which clinical manifestations? (Select all that apply.) a. Vitiligo b. Alopecia c. Intertrigo d. Erythema e. Actinic keratosis

ANS: C Hypernatremia is diagnosed by elevated serum sodium concentration. Blood pressure is not an accurate indicator of hypernatremia. Emesis and diarrhea will not stop because of intravenous therapy. Urine output is influenced by many factors, including extracellular fluid volume. A large dilute urine output can cause further hypernatremia.

The nurse is evaluating the effectiveness of the intravenous fluid therapy in a patient with hypernatremia. Which finding indicates goal achievement? a. Urine output increases to 150 mL/hr. b. Systolic and diastolic blood pressure decreases. c. Serum sodium concentration returns to normal. d. Large amounts of emesis and diarrhea decrease.

ANS: B Photophobia is not a normally occurring change with aging and would require further assessment. The other assessment data are common gerontologic differences in assessment and would not be unusual in a 76-yr-old patient.

The nurse is performing an eye examination on a 76-yr-old patient. Which finding indicates that the nurse should refer the patient for a more extensive assessment? a. The patient's sclerae are light yellow. b. The patient reports persistent photophobia. c. The pupil recovers slowly after responding to a bright light. d. There is a whitish gray ring encircling the periphery of the iris.

ANS: A Sodium is the most abundant cation in the blood. Potassium is the predominant intracellular cation. Chloride is an anion (negatively charged) rather than a cation (positively charged). Magnesium is found predominantly inside cells and in bone.

The nurse is reviewing laboratory results. Which cation will the nurse observe is the mostabundant in the blood? a. Sodium b. Chloride c. Potassium d. Magnesium

ANS: A The process of moving water from an area of low particle concentration to an area of higher particle concentration is known as osmosis. Filtration is mediated by fluid pressure from an area of higher pressure to an area of lower pressure. Diffusion is passive movement of electrolytes or other particles down the concentration gradient (from areas of higher concentration to areas of lower concentration). Active transport requires energy in the form of adenosine triphosphate (ATP) to move electrolytes across cell membranes against the concentration gradient (from areas of lower concentration to areas of higher concentration).

The nurse is teaching about the process of passively moving water from an area of lower particle concentration to an area of higher particle concentration. Which process is the nurse describing? a. Osmosis b. Filtration c. Diffusion d. Active transport

ANS: A When the Snellen chart is used to check visual acuity, the patient should stand 20 ft away. Accommodation is tested by looking at an object at both near and far distances. Shining a pen light into the eyes tests for pupil response. Following the examiner's fingers with the eyes tests extraocular movements.

The nurse is testing the visual acuity of a patient in the outpatient clinic. Which instructions should the nurse give for this test? a. "Stand 20 feet away from the wall chart." b. "Look at an object far away and then near to you." c. "Follow the examiner's finger with your eyes only." d. "Look straight ahead while I check your eyes with a light."

ANS: D The sudden change in peripheral vision may indicate an acute problem, such as retinal detachment, that should be treated quickly to preserve vision. The other data about the patient are not indicative of any acute problem. The other actions are also appropriate, but the highest priority for this patient is prevention of blindness.

The nurse is working in an urgent care clinic that has standardized treatment protocols for implementation by nursing staff. After reviewing the history, physical assessment, and vital signs for a 60-yr-old patient as shown in the accompanying figure, which action should the nurse take first? a. Check the patient's blood glucose level. b. Take the blood pressure on the left arm. c. Use an irrigating syringe to clean the ear canals. d. Report a vision change to the health care provider.

ANS: C Making eye contact with a partially sighted patient allows the patient to hear the nurse more easily and allows the nurse to assess the patient's facial expressions. The patient (rather than the spouse) should be asked first about any need for assistance. The information about the cause of the vision loss and assessment of the patient's visual acuity are not priorities during the initial assessment.

The nurse learns that a newly admitted patient has functional blindness and that the spouse has cared for the patient for many years. What is the nurse's most important action during the initial assessment? a. Obtain more information about the cause of the patient's vision loss. b. Obtain information from the spouse about the patient's special needs. c. Make eye contact with the patient and ask about any need for assistance. d. Perform an evaluation of the patient's visual acuity using a Snellen chart.

ANS: D The presence of acanthosis nigricans in skinfolds suggests either having type 2 diabetes or being at an increased risk for it. The description of the patient's skin does not indicate problems with fungal infection, poor hygiene, or the need to dry the skinfolds better

The nurse notes darker skin pigmentation in the skinfolds of a middle-aged patient who has a body mass index of 40 kg/m2. What is the nurse's appropriate action? a. Discuss the use of drying agents to minimize infection risk. b. Instruct the patient about the use of mild soap to clean skinfolds. c. Teach the patient about treating fungal infections in the skinfolds. d. Ask the patient about a personal or family history of type 2 diabetes

ANS: C Venous congestion increases capillary hydrostatic pressure. Increased hydrostatic pressure causes edema by causing increased movement of fluid into the interstitial area. Osmotic and oncotic pressures involve the concentrations of solutes and can contribute to edema in other situations, such as inflammation or malnutrition. Concentration pressure is not a nursing term

The nurse observes edema in a patient who has venous congestion from right heart failure. Which type of pressure facilitated the formation of the patient's edema? a. Osmotic b. Oncotic c. Hydrostatic d. Concentration

ANS: B Phosphate will decrease. Serum calcium and phosphate have an inverse relationship. When one is elevated, the other decreases, except in some patients with end-stage renal disease.

The nurse observes that the patient's calcium is elevated. When checking the phosphate level, what does the nurse expect to see? a. Increased b. Decreased c. Equal to calcium d. No change in phosphate

ANS: C Fungal cultures are obtained by swabbing the affected area of the skin with cotton-tipped applicators. Sterile gloves are not needed because it is not a sterile procedure. Local injection or aspiration is not involved in the procedure. The patch test is done to determine whether a patient is allergic to specific testing material, not for obtaining fungal specimens.

The nurse prepares to obtain a culture from a patient who has a possible fungal infection on the foot. Which items should the nurse gather for this procedure? a. Sterile gloves b. Patch test instruments c. Cotton-tipped applicators d. Syringe and intradermal needle

ANS: B Normal calcium range is 8.4 to 10.5 mg/dL; therefore, a value of 15.5 mg/dL is abnormally high and of concern. The rest of the laboratory values are within their normal ranges: sodium 136 to 145 mEq/L; potassium 3.5 to 5.0 mEq/L; and chloride 98 to 106 mEq/L.

The nurse receives the patient's most recent blood work results. Which laboratory value is of greatest concern? a. Sodium of 145 mEq/L b. Calcium of 15.5 mg/dL c. Potassium of 3.5 mEq/L d. Chloride of 100 mEq/L

ANS: A Increasing loss of peripheral vision is characteristic of glaucoma, and the patient should be scheduled for an examination as soon as possible. The other patients have symptoms commonly associated with aging: presbyopia, decreased tear formation, and impaired night vision.

The nurse working in the clinic receives telephone calls from several patients who want appointments as soon as possible. Which patient should be seen first? a. 71-yr-old who has noticed increasing loss of peripheral vision b. 74-yr-old who has difficulty seeing well enough to drive at night c. 60-yr-old who is reporting dry eyes with decreased tear formation d. 64-yr-old who states that it is becoming difficult to read news print

ANS: B In the case of chemical exposure, the nurse should begin treatment by flushing the eyes until the patient has been assessed by a health care provider and orders are available. No other interventions should delay flushing the eyes.

The occupational health nurse is caring for an employee who reporting bilateral eye pain after a cleaning solution splashed into the employee's eyes. Which action will the nurse take? a. Apply cool compresses. b. Flush the eyes with saline. c. Apply antiseptic ophthalmic ointment to the eyes. d. Cover the eyes with dry sterile patches and shields

ANS: A Change regular gowns by following these steps for maximum speed and arm mobility: (1) To remove a gown, remove the sleeve of the gown from the arm without the IV line, maintaining the patient's privacy. (2) Remove the sleeve of the gown from the arm with the IV line. (3) Remove the IV solution container from its stand, and pass it and the tubing through the sleeve. (If this involves removing the tubing from an EID, use the roller clamp to slow the infusion to prevent the accidental infusion of a large volume of solution or medication.)

The patient has an intravenous (IV) line and the nurse needs to remove the gown. In which order will the nurse perform the steps, starting with the first one? 1. Remove the sleeve of the gown from the arm without the IV. 2. Remove the sleeve of the gown from the arm with the IV. 3. Remove the IV solution container from its stand. 4. Pass the IV bag and tubing through the sleeve. a. 1, 2, 3, 4 b. 2, 3, 4, 1 c. 3, 4, 1, 2 d. 4, 1, 2, 3

ANS: C When using the sighted-guide technique, the nurse walks slightly in front and to the side of the patient and has the patient hold the nurse's elbow. The other techniques are not as safe in assisting a blind patient.

What is the safest technique for the nurse to use when assisting a blind patient to ambulate to the bathroom? a. Lead the patient slowly to the bathroom, holding on to the patient by the arm. b. Stay beside the patient and describe any obstacles on the path to the bathroom. c. Walk slightly ahead of the patient, allowing the patient to hold the nurse's elbow. d. Have the patient place a hand on the nurse's shoulder and guide the patient forward.

ANS: B Lenses are prescribed to correct the patient's near and distant vision. The nurse may assess for cloudiness of the lenses, increased intraocular pressure, and eye movement, but these data do not evaluate whether the patient's bifocals are effective.

What should the nurse assess to evaluate the effectiveness of treatment for the patient's myopia and presbyopia? a. Strength of the eye muscles. b. Both near and distant vision. c. Cloudiness in the eye lenses. d. Intraocular pressure changes.

ANS: C The posterior temporal lobe integrates the visual and auditory input for language comprehension. Reasoning and problem solving are functions of the anterior frontal lobe. Sensation on the left side of the body is located in the right postcentral gyrus. Voluntary movement on the right side is controlled in the left precentral gyrus.

What should the nurse include in a focused assessment of a patient's left posterior temporal lobe functions? a. Sensation on the left side of the body b. Reasoning and problem-solving ability c. Ability to understand written and oral language d. Voluntary movements on the right side of the body

ANS: C Baby shampoo is used to soften and remove crusts associated with blepharitis. The other interventions are not used in treating this disorder

What should the nurse teach a patient with recurrent staphylococcal and seborrheic blepharitis to do? a. Irrigate the eyes with saline solution. b. Schedule an appointment for eye surgery. c. Use a gentle baby shampoo to clean the eyelids. d. Apply cool compresses to the eyes three times daily.

ANS: B Hordeolum (styes) are commonly caused by Staphylococcus aureus, which may be present in cosmetics that the patient is using. Warm compresses are recommended to treat hordeolum. Antiseborrheic shampoos are recommended for seborrheic blepharitis. Patients with adult inclusion conjunctivitis, which is caused by Chlamydia trachomatis, should be referred for STI testing.

What should the nurse teach a patient with repeated hordeolum about how to prevent further infection? a. Apply cold compresses. b. Discard all used eye cosmetics. c. Wash the eyebrows with an antiseborrheic shampoo. d. Be examined for sexually transmitted infections (STIs).

ANS: B Fluorescein angiography involves injecting IV dye. If extravasation occurs, fluorescein is toxic to the tissues. Teach the patient to report any signs of extravasation, such as pain or burning. The nurse should closely monitor the IV site as well. The cornea is anesthetized during ultrasonography. Refractometry involves measuring visual acuity and asking the patient to choose lenses that are the sharpest; it is a painless test. The Amsler grid test involves using a hand-held card with grid lines. The patient fixates on the center dot and records any abnormalities of the grid lines.

What should the nurse teach the patient before fluorescein angiography? a. Hold a card and fixate on the center dot. b. Report any burning or pain at the IV site. c. Remain still while the cornea is anesthetized. d. Let the examiner know when images shown appear clear.

ANS: A When admitting a patient who is likely to be a poor historian, the nurse should obtain health history information from others who have knowledge about the patient's health. Waiting until the patient is oriented or obtaining only physiologic data will result in incomplete assessment data, which could adversely affect decision making about treatment. Asking leading questions may result in inaccurate or incomplete information.

When admitting an acutely confused patient with a head injury, which action should the nurse take? a. Ask family members about the patient's health history. b. Ask leading questions to assist in obtaining health data. c. Wait until the patient is better oriented to ask questions. d. Obtain only the physiologic neurologic assessment data.

ANS: C The patient has clinical manifestations that could be caused by systemic problems such as malnutrition or hypothyroidism, so further diagnostic evaluation is indicated. Patient teaching about nutrition, addressing the patient's dry skin, and referral to a podiatrist may also be needed, but the priority is to rule out underlying disease that may be causing these manifestations.

When assessing a new patient at the outpatient clinic, the nurse notes dry, scaly skin; thin hair; and thick, brittle nails. What is the nurse's most important action? a. Instruct the patient about the importance of nutrition for skin health. b. Make a referral to a podiatrist so that the nails can be safely trimmed. c. Consult with the health care provider about the need for further diagnostic testing. d. Teach the patient about using moisturizing creams and lotions to decrease dry skin.

ANS: B Angiomas are a common occurrence as patients get older, but they may occur with systemic problems such as liver disease. The patient may want to see a dermatologist to have the angiomas removed, but this is not the initial action by the nurse. The nurse may need to teach the patient about the effects of aging on the skin and about the effects of sun exposure, but the first action should be further assessment.

When performing a skin assessment, the nurse notes angiomas on the chest of an older patient. Which action should the nurse take next? a. Suggest an appointment with a dermatologist. b. Assess the patient for evidence of liver disease. c. Teach the patient about skin changes with aging. d. Discuss the use of sunscreen to prevent skin cancers.

ANS: C Petechiae are caused by pinpoint hemorrhages and are associated with a variety of serious disorders such as meningitis and coagulopathies. The nurse should contact the patient's health care provider about this finding for further diagnostic follow-up. The other skin changes are associated with aging. Although the other changes will also require ongoing monitoring or intervention by the nurse, they do not indicate a need for urgent action.

Which abnormality on the skin of an older patient is the priority for the nurse to discuss with the health care provider? a. Dry, scaly patches on the face b. Numerous varicosities on both legs c. Petechiae on the chest and abdomen d. Small dilated blood vessels on the face

ANS: B The Snellen test does not require nursing judgment and is appropriate to delegate to UAP who have been trained to perform it. History taking about infection or medications and assessment are actions that require critical thinking and should be done by the RN.

Which action can the nurse working in the emergency department delegate to an experienced unlicensed assistive personnel (UAP)? a. Ask a patient with decreased visual acuity about medications taken at home. b. Perform Snellen testing of visual acuity for a patient with a history of cataracts. c. Obtain information from a patient about any history of childhood ear infections. d. Inspect a patient's external ear for redness, swelling, or presence of skin lesions.

ANS: B Using standardized screening tests such as a Snellen chart to test visual acuity is included in LPN education and scope of practice. Evaluation, assessment, and patient teaching are higher level skills that require RN education and scope of practice.

Which action could the registered nurse (RN) who is working in the clinic delegate to a licensed practical/vocational nurse (LPN/VN)? a. Evaluate a patient's ability to administer eyedrops. b. Check a patient's visual acuity using a Snellen chart. c. Inspect a patient's external ear for signs of irritation caused by a hearing aid. d. Teach a patient with otosclerosis about use of sodium fluoride and vitamin D.

ANS: B The glossopharyngeal and vagus nerves innervate the pharynx and control the gag reflex. A patient with impaired function of these nerves is at risk for aspiration. An oral airway may be needed when a patient is unconscious and unable to maintain the airway, but it will not decrease aspiration risk. Taste and eye blink are controlled by the facial nerve. Balance and coordination are cerebellar functions

Which action should the nurse include in the plan of care for a patient with impaired functioning of the left glossopharyngeal nerve (CN IX) and vagus nerve (CN X)? a. Assist to stand and ambulate. b. Withhold oral fluids and food. c. Insert an oropharyngeal airway. d. Apply artificial tears every hour.

ANS: A, C Skills such as administration of patch testing and sterile dressing technique are included in LPN/VN education and scope of practice. Obtaining a health history and patient education require registered nurse (RN) level education and scope of practice.

Which activities can the nurse working in the outpatient clinic delegate to a licensed practical/vocational nurse (LPN/VN)? (Select all that apply.) a. Administer patch testing to a patient with allergic dermatitis. b. Interview a new patient about chronic health problems and allergies. c. Apply a sterile dressing after the health care provider excises a mole. d. Explain potassium hydroxide testing to a patient with a skin infection. e. Teach a patient about site care after a punch biopsy of an upper arm lesion.

ANS: B Classic signs of cataracts include blurred vision and light sensitivity. Thyroid problems are a major cause of exophthalmos. Unequal pupil is not indicative of cataracts. Loss of peripheral vision is a sign of glaucoma.

Which assessment finding alerts the nurse to provide patient teaching about cataract development? a. Unequal pupil size b. Sensitivity to light c. Loss of peripheral vision d. History of hyperthyroidism

ANS: B, C The cerebellum is responsible for coordination and is assessed by looking at the patient's gait and the finger-to-nose test. The other assessments will be used for other parts of the neurologic assessment.

Which assessments should the nurse make to monitor a patient's cerebellar function? (Select all that apply.) a. Test for graphesthesia. b. Observe arm swing with gait. c. Perform the finger-to-nose test. d. Assess heat and cold sensation. e. Measure strength against resistance

ANS: A, C, F Infiltration results in skin that is edematous near the IV insertion site. Skin is cool to the touch and may be pale or discolored. Pain, warmth, erythema, a reddish streak, and a palpable venous cord are all symptoms of phlebitis.

Which assessments will alert the nurse that a patient's IV has infiltrated? (Select all that apply.) a. Edema of the extremity near the insertion site b. Reddish streak proximal to the insertion site c. Skin discolored or pale in appearance d. Pain and warmth at the insertion site e. Palpable venous cord f. Skin cool to the touch

ANS: B The protein level is high. The specific gravity, WBCs, and glucose values are normal.

Which cerebrospinal fluid analysis result should the nurse recognize as abnormal and communicate to the health care provider? a. Specific gravity of 1.007 b. Protein of 65 mg/dL (0.65 g/L) c. Glucose of 45 mg/dL (1.7 mmol/L) d. White blood cell (WBC) count of 4 cells/L

ANS: B Vibration sense is testing by touching the patient with a vibrating tuning fork. The other equipment is needed for testing of pain sensation, reflexes, and two-point discrimination.

Which equipment should the nurse obtain to assess vibration sense in a patient with diabetes who has peripheral nerve dysfunction? a. Sharp pin b. Tuning fork c. Reflex hammer d. Calibrated compass

ANS: D Accommodation is defined as the ability of the lens to adjust to various distances. The pupils constrict while fixating on an object that is being moved from far away to near the eyes. The other responses may also be elicited as part of the eye examination, but they do not indicate accommodation.

Which finding by the nurse performing an eye examination indicates that the patient has normal accommodation? a. After covering one eye for 1 minute, the pupil constricts as the cover is removed. b. Shining a light into the patient's eye causes pupil constriction in the opposite eye. c. A blink reaction occurs after touching the patient's pupil with a piece of sterile cotton. d. The pupils constrict while fixating on an object being moved toward the patient's eyes.

ANS: B Because the cell bodies of lower motor neurons are located in the spinal cord, damage to the neuron will decrease motor activity of the affected muscles. Spasticity and hyperactive reflexes are caused by upper motor neuron damage. Sensation is not impacted by motor neuron lesions

Which finding should the nurse expect when assessing the legs of a patient who has a lower motor neuron lesion? a. Spasticity b. Flaccidity c. Impaired sensation d. Hyperactive reflexes

ANS: B Although changes in appetite are normal with aging, a 15-pound weight loss requires further investigation. Orthostatic drops in blood pressure, changes in sleep patterns, and slowing of reflexes are normal changes in aging.

Which information about a 76-yr-old patient should the nurse identify as uncharacteristic of normal aging? a. Triceps reflex response graded at 1/5 b. Unintended weight loss of 15 pounds c. Patient report of chronic difficulty in falling asleep d. 10 mm Hg orthostatic drop in systolic blood pressure

ANS: B The pupils are dilated using cycloplegic medications during refractometry. This effect will last several hours and cause photophobia. The other teaching would not be appropriate for a patient who was having refractometry

Which information will the nurse provide to the patient scheduled for refractometry? a. "You should not take any of your eye medicines before the examination." b. "You will need to wear sunglasses for a few hours after the examination." c. "The doctor will shine a bright light into your eye during the examination." d. "The surface of your eye will be numb while the doctor does the examination."

ANS: A The best way to avoid the spread of infection from one eye to another is to avoid rubbing or touching the eyes and to use careful hand washing when touching the eyes is unavoidable. Occlusive dressings are not used for herpes keratitis. Herpes simplex is a virus, and antibiotic drops will not be prescribed. Topical corticosteroids are immunosuppressive and typically are not ordered because they can contribute to a longer course of infection and more complications

Which instruction should the nurse include in a teaching plan for a patient with herpes simplex keratitis? a. Wash hands frequently and avoid touching the eyes. b. Apply antibiotic drops to the eye several times daily. c. Apply a new occlusive dressing to the affected eye at bedtime. d. Use corticosteroid ophthalmic ointment to decrease inflammation

ANS: B Because the patient will be receiving antibiotics to treat the pneumonia, the nurse should be most concerned about her history of allergic rashes. The nurse needs to do further assessment of possible causes of the allergic rashes and whether she has ever had allergic reactions to any drugs, especially antibiotics. The assessment data in the other response would be normal for an older patient

Which integumentary assessment data from an older patient admitted with bacterial pneumonia should be of concern to the nurse? a. Brown macules on extremities b. Reports a history of allergic rashes c. Skin wrinkled with tenting on both hands d. Longitudinal nail ridges and sparse scalp hair

ANS: B, D, E Because a catheter is inserted into an artery (e.g., the femoral artery) during cerebral angiography, the nurse should assess for bleeding at the site and bleeding that may affect pulse and blood pressure. Neuro status should be assessed often. There is no reason to keep the patient NPO. Photophobia is not expected.

Which nursing actions should be included in the plan of care for a patient after cerebral angiography? (Select all that apply.) a. Monitor for photophobia. b. Observe for bleeding at the puncture site. c. Keep patient NPO until gag reflex returns. d. Check pulse and blood pressure frequently. e. Assess orientation to person, place, and time

ANS: B Application of cold and warm packs is included in UAP education and the ability to accomplish this safely would be expected for UAP working in an eye clinic. Medication administration, patient teaching, and assessment are high-level skills appropriate for the education and legal practice level of the RN.

Which nursing activity is appropriate for the registered nurse (RN) working in the eye clinic to delegate to experienced unlicensed assistive personnel (UAP)? a. Instilling antiviral drops for a patient with a corneal ulcer b. Application of a warm compress to a patient's hordeolum c. Instruction about hand washing for a patient with herpes keratitis d. Checking for eye irritation in a patient with possible conjunctivitis

ANS: B Vital centers that control respiration are located in the medulla and part of the brainstem. They require priority assessments because changes in respiratory function may be life threatening. The other information will also be obtained by the nurse but is not as urgent.

Which of the following should the nurse consider the priority nursing assessment for a patient being admitted with a brainstem infarction? a. Pupil reaction b. Respiratory rate c. Reflex reaction time d. Level of consciousness

ANS: B The history and symptoms suggest eye trauma with a possible penetrating injury. Blindness may occur unless the patient is assessed and treated rapidly. The other patients should be treated as soon as possible, but do not have clinical manifestations that indicate any acute risk for vision or hearing loss.

Which patient arriving at the urgent care center will the nurse assess first? a. Patient who is reporting that the left eyelid has just started to droop b. Patient with acute right eye pain that began while using power tools c. Patient with purulent left eye discharge and conjunctival inflammation d. Patient who has redness, crusting, and swelling along the lower right lid margin

ANS: B The most immediate concern for the patient is to lower intraocular pressure, which will occur most rapidly with IV administration of a hyperosmolar diuretic such as mannitol. The other medications are also appropriate for a patient with glaucoma but would not be the first medication administered

Which prescribed medication should the nurse give first to a patient who has just been admitted to a hospital with acute angle-closure glaucoma? a. Morphine sulfate 4 mg IV b. Mannitol (Osmitrol) 100 mg IV c. Betaxolol (Betoptic) 1 drop in each eye d. Acetazolamide (Diamox) 250 mg orally

ANS: B A positive Romberg test result indicates that the patient has difficulty maintaining balance when standing with the eyes closed. The Romberg test does not assess orientation, thermoregulation, or discomfort.

Which problem should the nurse expect for a patient who has a positive Romberg test result? a. Pain b. Falls c. Aphasia d. Confusion

ANS: B Contact lenses should not be used when patients have conjunctivitis because they can further irritate the conjunctiva. Hand washing is the major means to prevent the spread of conjunctivitis. Infection may be spread by sharing towels or other contact. It is common for bacterial conjunctivitis to spread through a family or other group in close contact.

Which statement by a patient with bacterial conjunctivitis indicates a need for further teaching? a. "I will wash my hands often during the day." b. "I will remove my contact lenses at bedtime." c. "I will not share towels with my friends or family." d. "I will monitor my family for eye redness or drainage."

ANS: D Various types of magnifiers can enhance the remaining vision enough to allow theperformance of many tasks and activities of daily living. Audio books, Braille instruction, and canes usually are reserved for patients with no functional vision.

Which teaching point should the nurse plan to include when caring for a patient whose vision is corrected to 20/200? a. How to access audio books? b. How to use a white cane safely? c. Where Braille instruction is available? d. Where to obtain hand-held magnifiers?

ANS: D Seizure disorders are usually assessed using EEG testing. Evoked potential is used to diagnose problems with the visual or auditory systems. Cerebral angiography is used to diagnose vascular problems. EMG is used to evaluate electrical innervation to skeletal muscle.

Which test should the nurse anticipate discussing with a patient who has a possible seizure disorder? a. Cerebral angiography b. Evoked potential studies c. Electromyography (EMG) d. Electroencephalography (EEG)

ANS: B Antibiotic and corticosteroid eyedrops are commonly prescribed after cataract surgery. The patient should be able to administer them using safe technique. Pain is not expected after cataract surgery, and opioids will not be needed. Coughing and deep breathing exercises are not needed because a general anesthetic agent is not used. There is no bed rest restriction after cataract surgery.

Which topic will the nurse teach after a patient has had outpatient cataract surgery and lens implantation? a. Use of oral opioids for pain control b. Administration of corticosteroid drops c. Need for bed rest for 1 to 2 days after the surgery d. Importance of coughing and deep breathing exercises
