A patient has been prescribed celecoxib [Celebrex] to treat arthritis. The nurse will contact the healthcare provider if the patient shows symptoms of which condition? a) anemia b) cataracts c) glaucoma d) hyperthyroidism

A Celecoxib [Celebrex] is a COX-2 inhibitor that is contraindicated in patients with anemia. Celecoxib can cause an increased risk of gastrointestinal adverse effects, including bleeding, which can worsen anemia. The other conditions are not contraindications for use of the COX-2 inhibitor.

Which intervention is most appropriate for a patient who needs treatment for acute postoperative pain? a) administer ketorolac IV every 6 hours PRN. b) Administer acetaminophen PO every 4 hours. c) Administer celecoxib [Celebrex] PO every 6 hours. d) Administer indomethacin [Indocin] PO every 4 hours

A Ketorolac is the only nonsteroidal anti-inflammatory drug (NSAID) that can be administered by injection (intramuscularly or intravenously) and is indicated for short-term use for severe-to-moderate pain. Acute postoperative pain cannot be effectively managed on oral medication.

The nurse is responsible for dispensing medications and notes that the patient has a Schedule IV drug. What should the nurse interpret from this? Select all that apply. a) The drug is a controlled substance. b) The drug has a high potential for abuse. c) The prescription is valid for only 1 year. d) The drug can be filled without a prescription. e) The drug is dispensed via an approved protocol.

A, B Controlled drugs are classified into five categories. A Schedule IV drug is a controlled substance whose use is limited. The drug has a high potential for abuse. Schedule I drugs need to be dispensed via an approved protocol because they have a high potential for causing dependency. The prescription of a Schedule IV drug is valid for only 6 months with a maximum of five refills during that period. Schedule IV drugs must have a valid prescription before being filled.

A nurse instructs a patient to discontinue the scheduled use of high-dose aspirin before undergoing which procedure(s)? Select all that apply. a) hysterectomy b) cataract surgery c) cholecystectomy d) removal of a skin mole e) routine dental cleaning

A, C Aspirin promotes bleeding by causing irreversible suppression of platelet aggregation. High-dose aspirin should be discontinued 1 week before elective surgery (cholecystectomy, hysterectomy). There is no need to stop aspirin before procedures with a low risk of bleeding such as dental cleaning or dermatologic or cataract surgery.

Which statement(s) about the care of a patient with aspirin poisoning does the nurse identify as correct? Select all that apply. a) Hemodialysis or peritoneal dialysis can accelerate salicylate removal. b) Warming blankets are routinely used to raise the patient's temperature. c) Activated charcoal is contraindicated in the treatment of aspirin poisoning. d) Bicarbonate infusions are used to reverse acidosis and promote renal excretion of salicylate. e) Diuretics and fluid restrictions are needed to correct the fluid overload commonly seen with aspirin poisoning.

A, D Aspirin poisoning is an acute medical emergency that requires hospitalization. Treatment is largely supportive and consists of external cooling (eg, sponging with tepid water), infusion of fluids (to correct dehydration and electrolyte loss), infusion of bicarbonate (to reverse acidosis and promote renal excretion of salicylates), and mechanical ventilation (if respiration is severely depressed). Absorption of aspirin can be reduced by gastric lavage and by giving activated charcoal. If necessary, hemodialysis or peritoneal dialysis can accelerate salicylate removal.

A patient sustains significant burns to the skin and is experiencing fluid shift associated with edema in the fluid overload phase. The nurse would anticipate that this will interfere most with which phase of pharmacodynamics? A. Absorption B. Distribution C. Metabolism Excretion

A. Distribution

Which is a physiologic change seen in the older adult that has an effect on drug administration? A.Lower (acidic) gastric secretions B.Increased first-pass effect through the liver C.Increased glomerular filtration rate D.Lower cardiac output

A.Lower cardiac output •Rationale: Lower cardiac output is a physiologic change associated with the older adult. The pH increases, not decreases, causing alkaline gastric secretions. The first-pass effect through the liver is decreased. The glomerular filtration rate is decreased.

A patient has liver and kidney disease. He is given a medication with a half-life of 30 hours. What is the expected duration of this medication? A.increase. B.decrease. C.remain unchanged. D.dissipate.

A.increase. build up in body -no metabolism = no excretion

When administering medications to the older adult population, the nurse is aware that the physiologic changes of aging that can affect drug activity include all of the following except A.increased fat-to-water ratio. B.decreased liver enzyme production. C.loss of nephrons. D.increased gastrointestinal blood flow.

A.increased gastrointestinal blood flow. Rationale: Older adults have decreased gastric acidity, reduced peristalsis, decreased body water, increased fat-to-water ratio, decreased numbers of functioning nephrons, and decreased liver enzyme production and function.

A patient is to receive codeine, 40 mg subcutaneously, every 6 hours as needed for pain. The solution is available in a concentration of 30 mg/mL. Identify how many milliliters of codeine will be drawn up for this dose. (record answer to one decimal place) _______

ANS: 1.3 mL

A patient was diagnosed with pancreatic cancer last month, and has complained of a dull ache in the abdomen for the past 4 months. This pain has been gradually increasing, and the pain relievers taken at home are no longer effective. What type of pain is the patient experiencing? a. Acute pain b. Chronic pain c. Somatic pain d. Neuropathic pain

ANS: B Chronic pain is associated with cancer and is characterized by slow onset, long duration, and dull, persistent aching. The patient's symptoms are not characteristics of acute pain, somatic pain, or neuropathic pain.

The nurse is reviewing herbal therapies. Which is a common use of the herb feverfew? a. Muscle aches b. Migraine headaches c. Leg cramps d. Incision pain after surgery

ANS: B Feverfew is commonly used for migraine headaches, menstrual problems, arthritis, and fever. Possible adverse effects include muscle stiffness and muscle and joint pain.

A 57-year-old woman being treated for end-stage breast cancer has been using a transdermal opioid analgesic as part of the management of pain. Lately, she has been experiencing breakthrough pain. The nurse expects this type of pain to be managed by which of these interventions? a. Administering NSAIDs b. Administering an immediate-release opioid c. Changing the opioid route to the rectal route d. Making no changes to the current therapy

ANS: B If a patient is taking long-acting opioid analgesics, breakthrough pain must be treated with an immediate-release dosage form that is given between scheduled doses of the long-acting opioid. The other options are not appropriate actions.

A patient is recovering from abdominal surgery, which he had this morning. He is groggy but complaining of severe pain around his incision. What is the most important assessment data to consider before the nurse administers a dose of morphine sulfate to the patient? a. His pulse rate b. His respiratory rate c. The appearance of the incision d. The date of his last bowel movement

ANS: B One of the most serious adverse effects of opioids is respiratory depression. The nurse must assess the patient's respiratory rate before administering an opioid. The other options are incorrect.

A patient has been treated for lung cancer for 3 years. Over the past few months, the patient has noticed that the opioid analgesic is not helping as much as it had previously and more medication is needed for the same pain relief. The nurse is aware that this patient is experiencing which of these? a. Opioid addiction b. Opioid tolerance c. Opioid toxicity d. Opioid abstinence syndrome

ANS: B Opioid tolerance is a common physiologic result of long-term opioid use. Patients with opioid tolerance require larger doses of the opioid agent to maintain the same level of analgesia. This situation does not describe toxicity (overdose), addiction, or abstinence syndrome (withdrawal).

Vicodin (acetaminophen/hydrocodone) is prescribed for a patient who has had surgery. The nurse informs the patient that which common adverse effects can occur with this medication? (Select all that apply.) a. Diarrhea b. Constipation c. Lightheadedness d. Nervousness e. Urinary retention f. Itching

ANS: B, C, E, F Constipation (not diarrhea), lightheadedness (not nervousness), urinary retention, and itching are some of the common adverse effects that the patient may experience while taking Vicodin.

A patient is to receive acetylcysteine (Mucomyst) as part of the treatment for an acetaminophen (Tylenol) overdose. Which action by the nurse is appropriate when giving this medication? a. Giving the medication undiluted for full effect b. Avoiding the use of a straw when giving this medication c. Disguising the flavor with soda or flavored water d. Preparing to give this medication via a nebulizer

ANS: C Acetylcysteine has the flavor of rotten eggs and so is better tolerated if it is diluted and disguised by mixing with a drink such as cola or flavored water to help increase its palatability. The use of a straw helps to minimize contact with the mucous membranes of the mouth and is recommended. The nebulizer form of this medication is used for certain types of pneumonia, not for acetaminophen overdose.

A patient is suffering from tendonitis of the knee. The nurse is reviewing the patient's medication administration record and recognizes that which adjuvant medication is most appropriate for this type of pain? a. Antidepressant b. Anticonvulsant c. Corticosteroid d. Local anesthesia

ANS: C Corticosteroids have an anti-inflammatory effect, which may help to reduce pain. The other medications do not have anti-inflammatory properties.

A patient will be discharged with a 1-week supply of an opioid analgesic for pain management after abdominal surgery. The nurse will include which information in the teaching plan? a. How to prevent dehydration due to diarrhea b. The importance of taking the drug only when the pain becomes severe c. How to prevent constipation d. The importance of taking the drug on an empty stomach

ANS: C Gastrointestinal (GI) adverse effects, such as nausea, vomiting, and constipation, are the most common adverse effects associated with opioid analgesics. Physical dependence usually occurs in patients undergoing long-term treatment. Diarrhea is not an effect of opioid analgesics. Taking the dose with food may help minimize GI upset.

A 38-year-old man has come into the urgent care center with severe hip pain after falling from a ladder at work. He says he has taken several pain pills over the past few hours but cannot remember how many he has taken. He hands the nurse an empty bottle of acetaminophen (Tylenol). The nurse is aware that the most serious toxic effect of acute acetaminophen overdose is which condition? a. Tachycardia b. Central nervous system depression c. Hepatic necrosis d. Nephropathy

ANS: C Hepatic necrosis is the most serious acute toxic effect of an acute overdose of acetaminophen. The other options are incorrect.

The nurse is assessing a patient for contraindications to drug therapy with acetaminophen (Tylenol). Which patient should not receive acetaminophen? a. A patient with a fever of 101° F (38.3° C) b. A patient who is complaining of a mild headache c. A patient with a history of liver disease d. A patient with a history of peptic ulcer disease

ANS: C Liver disease is a contraindication to the use of acetaminophen. Fever and mild headache are both possible indications for the medication. Having a history of peptic ulcer disease is not a contraindication.

A 78-year-old patient is in the recovery room after having a lengthy surgery on his hip. As he is gradually awakening, he requests pain medication. Within 10 minutes after receiving a dose of morphine sulfate, he is very lethargic and his respirations are shallow, with a rate of 7 per minute. The nurse prepares for which priority action at this time? a. Assessment of the patient's pain level b. Immediate intubation and artificial ventilation c. Administration of naloxone (Narcan) d. Close observation of signs of opioid tolerance

ANS: C Naloxone, an opioid-reversal agent, is used to reverse the effects of acute opioid overdose andis the drug of choice for reversal of opioid-induced respiratory depression. This situation is describing an opioid overdose, not opioid tolerance. Intubation and artificial ventilation are not appropriate because the patient is still breathing at 7 breaths/min. It would be inappropriate to assess the patient's level of pain.

The nurse is assessing a patient who has been admitted to the emergency department for a possible opioid overdose. Which assessment finding is characteristic of an opioid drug overdose? a. Dilated pupils b. Restlessness c. Respiration rate of 6 breaths/min d. Heart rate of 55 beats/min

ANS: C The most serious adverse effect of opioid use is CNS depression, which may lead to respiratory depression. Pinpoint pupils, not dilated pupils, are seen. Restlessness and a heart rate of 55 beats/min are not indications of an opioid overdose.

A patient arrives at the urgent care center complaining of leg pain after a fall when rock climbing. The x-rays show no broken bones, but he has a large bruise on his thigh. The patient says he drives a truck and does not want to take anything strong because he needs to stay awake. Which statement by the nurse is most appropriate? a. "It would be best for you not to take anything if you are planning to drive your truck." b. "We will discuss with your doctor about taking an opioid because that would work best for your pain." c. "You can take acetaminophen, also known as Tylenol, for pain, but no more than 1000 mg per day." d. "You can take acetaminophen, also known as Tylenol, for pain, but no more than 3000 mg per day."

ANS: D Acetaminophen is indicated for mild-to-moderate pain and does not cause drowsiness, as an opioid would. Currently, the maximum daily amount of acetaminophen is 3000 mg/day. The 1000-mg amount per day is too low. Telling the patient not to take any pain medications is incorrect.

The drug nalbuphine (Nubain) is an agonist-antagonist (partial agonist). The nurse understands that which is a characteristic of partial agonists? a. They have anti-inflammatory effects. b. They are given to reverse the effects of opiates. c. They have a higher potency than agonists. d. They have a lower dependency potential than agonists.

ANS: D Partial agonists such as nalbuphine are similar to the opioid agonists in terms of their therapeutic indications; however, they have a lower risk of misuse and addiction. They do not have anti-inflammatory effects, nor are they given to reverse the effects of opiates. They do not have a higher potency than agonists.

An 18-year-old basketball player fell and twisted his ankle during a game. The nurse will expect to administer which type of analgesic? a. Synthetic opioid, such as meperidine (Demerol) b. Opium alkaloid, such as morphine sulfate c. Opioid antagonist, such as naloxone HCL (Narcan) d. Nonopioid analgesic, such as indomethacin (Indocin)

ANS: D Somatic pain, which originates from skeletal muscles, ligaments, and joints, usually responds to nonopioid analgesics such as nonsteroidal anti-inflammatory drugs (NSAIDs). The other options are not the best choices for somatic pain.

An adolescent patient who has acne is given a regimen of topical medications and an oral antibiotic that generally clears up lesions to fewer than 10 within 6 to 8 weeks. At a 2-month follow-up, the patient continues to have more than 25 lesions. The child's parent affirms that the child is using the medications as prescribed. Which statement below is correct for this patient to evaluate the outcome? a. "Goal of fewer than 10 lesions in 6 to 8 weeks is not met." b. "Goal that the medication will be effective is not met." c. "Goal that the patient will take medications as prescribed is not met." d. "Goal that the patient understands the medication regimen is not met."

ANS: a All indications are that this patient is taking the medications and they are not effective. The first statement is correct because it identifies a measurable desired outcome and a specific time frame.

The nurse is preparing to administer a medication and reviews the patient's chart for drug allergies, serum creatinine, and blood urea nitrogen (BUN) levels. The nurse's actions are reflective of which of the following? a. Recognizing cues (assessment) b. Analyze cues & prioritize hypothesis (analysis) c. Take action (nursing interventions) d. Generate solutions (planning)

ANS: a Recognizing cues (assessment) involves gathering subjective and objective information about the patient and the medication. Laboratory values from the patient's chart would be considered collection of objective data.

Which of the following would be correctly categorized as objective data? a. A list of herbal supplements regularly used provided by the patient. b. Lab values associated with the drugs the patient is taking. c. The ages and relationship of all household members to the patient. d. Usual dietary patterns and food intake.

ANS: b Objective data are measured and detected by another person and would include lab values. The other examples are subjective data.

A school-age child will begin taking a medication to be administered at 5 mL three times daily. The child's parent tells the nurse that, with a previous use of the drug, the child repeatedly forgot to bring the medication home from school, resulting in missed evening doses. What will the nurse recommend? a. Encourage the child to be more responsible and that it is important to take the medication as prescribed. b. Putting a note on the child's locker to encourage the child to take responsibility for medication administration. c. Asking the provider if 7.5 mL may be taken in the morning and 7.5 mL may be taken in the evening so that the correct amount is given daily. d. Taking the noon dose to school every day and giving it to the school nurse to administer.

ANS: c For busy families with school-age children, it may be necessary to adjust the medication schedule to one that fits their schedule. The nurse should ask the provider if a revised schedule is possible. In this case, the most effective revised schedule would involve not taking the medication while at school. Putting a note on the locker is not likely to be effective. It is not correct to adjust the dose.

A high-school student regularly forgets to use a twice-daily inhaled corticosteroid to prevent asthma flares and is repeatedly admitted to the hospital. The child's parent tells the nurse that the child has been told that forgetting to take the medication causes frequent hospitalizations. The nurse will... a. encourage the child to take responsibility for taking the medication. b. reinforce the need to take prescribed medications to avoid hospitalizations. c. suggest putting the inhaler with the child's toothbrush to use before brushing teeth. d. suggest that the child's parents administer the medication to increase compliance.

ANS: c It is important to empower patients to take responsibility for managing medications. Putting the medication with the toothbrush can help this child remember to use it. Telling the child to take medications and reminding the child that failure to do so results in hospitalization is not working. Asking the child's parents to administer the medication does not empower the adolescent to take responsibility.

An older patient must learn to administer a medication using a device that requires manual dexterity. The patient becomes frustrated and expresses lack of self-confidence in performing this task. Which action will the nurse perform next? a. Ask the patient to keep trying until the skill is learned. b. Provide written instructions with illustrations showing each step of the skill. c. Schedule multiple sessions and practice each step separately. d. Teach the procedure to family members who can administer the medication for the patient.

ANS: c Nurses should be sensitive to patient's level of frustration when teaching skills. In this case, breaking the steps down into individual parts will help with this patient's frustration level.

Which of the following would not be considered an important element of health teaching in drug therapy? a. Assess the patients' health literacy skills. b. Assess all of the drugs on the patients' chart for possible drug interactions. c. Avoid discussing potential side effects and adverse reactions with the patient to avoid nonadherence. d. Determine if the patient needs laboratory monitoring.

ANS: c Potential side effects and adverse reactions should always be discussed with the patient so they know what to report to their health care team should they occur. All other factors considerations listed are important elements of health teaching.

The nurse reviews a patient's database and learns that the patient lives alone, is forgetful, and does not have an established routine. The patient will be sent home with three new medications to be taken at di昀昀erent times of the day. The nurse develops a daily medication chart and enlists a family member to put the patient's pills in a pill organizer. This is an example of which element of the nursing process? a. Recognizing cues (assessment) b. Analyze cues & prioritize hypothesis (analysis) c. Take action (nursing interventions) d. Generate solutions (planning)

ANS: c Taking action (nursing interventions) involves education and patient care in order to assist the patient to accomplish the goals of treatment.

The nurse is using data collected to delegate a set of interventions to achieve the most desirable outcomes. Which of the following steps is the nurse applying? a. Recognizing cues (assessment) b. Analyze cues & prioritize hypothesis (analysis) c. Generate solutions (planning) d. Take action (nursing interventions)

ANS: c When generating solutions (planning), the nurse identifies expected outcomes and uses the patient's problem(s) to define a set of interventions to achieve the most desirable outcomes. Recognizing cues (assessment) involves the gathering of cues (information) from the patient about their health and lifestyle practices, which are important facts that aid the nurse in making clinical care decisions. Prioritizing hypothesis is used to organize and rank the patient problem(s) identified. Finally, taking action involves implementation of nursing interventions to accomplish the expected outcomes.

A patient will be sent home with a metered-dose inhaler, and the nurse is providing teaching. Which is a correctly written expected outcome for this process? a. The nurse will demonstrate the correct use of a metered-dose inhaler to the patient. b. The nurse will teach the patient how to administer medication with a metered-dose inhaler. c. The patient will know how to self-administer the medication using the metered-dose inhaler. d. The patient will independently administer the medication using the metered-dose inhaler at the end of the session.

ANS: d Expected outcomes must be patient-centered and clearly state the outcome with a reasonable deadline and should identify components for evaluation. PTS: 1

A patient who is hospitalized for chronic obstructive pulmonary disease (COPD) wants to go home. The nurse and the patient discuss the patient's situation and decide that the patient may go home when able to perform self- care without dyspnea and hypoxia. This is an example of which phase of the nursing process? a. Recognizing cues (assessment) b. Analyze cues & prioritize hypothesis (analysis) c. Take action (nursing interventions) d. Generate solutions (planning)

ANS: d Generating solutions (planning) involves delegating a set of interventions to achieve the most desirable outcomes, which, for this patient, means being able to perform self-care activities without dyspnea and hypoxia.

All of the following would be considered subjective data, EXCEPT: a. Patient-reported health history b. Patient-reported signs and symptoms of their illness c. Financial barriers reported by the patient's caregiver d. Vital signs obtained from the medical record

ANS: d Subjective data is based on what patients or family members communicate to the nurse. Patient-reported health history, signs and symptoms, and caregiver-reported financial barriers would be considered subjective data. Vital signs obtained from the medical record would be considered objective data

A 5-year-old child with type 1 diabetes mellitus has had repeated hospitalizations for episodes of hyperglycemia. The parents tell the nurse that they can't keep track of everything that has to be done to care for their child. The nurse reviews medications, diet, and symptom management with the parents and draws up a daily checklist for the family to use. These activities are completed in which step of the nursing process? a. Recognizing cues (assessment) b. Analyze cues & prioritize hypothesis (analysis) c. Generate solutions (planning) d. Take action (nursing interventions)

ANS: d Taking action through nursing interventions is where the nurse provides patient health teaching, drug administration, patient care, and other interventions necessary to assist the patient in accomplishing expected outcomes.

The nurse is developing a teaching plan for an elderly patient who will begin taking an antihypertensive drug that causes dizziness and orthostatic hypotension. Which hypothesis (problem) documented by the nurse is appropriate for this patient? a. Deficient knowledge related to drug side effects. b. Ineffective health maintenance related to age. c. Readiness for enhanced knowledge related to medication side effects. d. Risk for injury related to side effects of the medication.

ANS: d This patient has an increased risk for injury because of drug side effects, so this is an appropriate hypothesis (problem) to direct the type of care and follow-up the patient will receive.

Which statement places the four processes of pharmacokinetics in the correct sequence?

Absorption, distribution, metabolism, excretion

The doctor ordered a patient who is post-op from surgery to receive 2 mg of IV Morphine. The patient can have the pain medication every 4 hours PRN for a breakthrough pain rating of 5 or greater on 1-10 scale. The patient's current pain rating is a 6 on 1-10 scale. The patient's last dose was at 0400 and it is now 1000. You administer the medication as ordered. What information will you include in your documentation? Select all that applies: A. Pain Rating B. Route C. Location of the Pain D. Dosage E. Medication Name F. Current Vital Signs G. Follow-up Pain Rating H. Time

All the answers are correct. This nurse would want to include all the information above when documenting.

Drugs that are _________ block responses

Antagonists

Which interventions regarding drug therapy should the nurse implement?

Assess for side effects, with a focus on undesirable side-effects, check reference books or drug inserts before administering the medication, evaluate Peak and trough levels before administering drugs with a narrow therapeutic range, check the patient's serum therapeutic range of drugs that have a narrow therapeutic range

A nurse should recognize that a patient who takes an angiotensin-converting enzyme (ACE) inhibitor while also taking high-dose aspirin is at risk of developing which complication? a) hemorrhage b) renal failure c) liver toxicity d) congestive heart failure

B High-dose aspirin therapy should be avoided in patients taking ACE inhibitors. In susceptible patients, these medications can impair renal function when they are combined with aspirin. Liver toxicity, congestive heart failure, and hemorrhage are not effects of ACE inhibitor and aspirin interactions.

Which route of drug absorption has the greatest bioavailability?

Intravenous

The patient has been taking aspirin long term for a chronic inflammatory illness. Which adverse effects should the nurse teach the patient to report? Select all that apply. a) diaphoresis b) black, tarry stools c) ringing in the ears d) bleeding of the gums e) increase in urine output

B, C, D Increase in bleeding is an adverse effect of aspirin. Black, tarry stools and bleeding of the gums are both indications this could be occurring. Ringing in the ears is a symptom of salicylism, a syndrome that occurs when therapeutic levels are slightly elevated. Diaphoresis could indicate reduction of fever, which is a desired effect of aspirin. Aspirin can cause renal impairment, which is characterized by decreased urine output.

Which information will the nurse include in the patient teaching? (Select all that apply.) A.Cost of drugs B.Administration technique C.Instructions regarding drug discontinuation D.Foods to avoid when taking a certain drug E.Side effects to report to health care provider

B,D,E,C -nurses don't know the cost of drugs

Which of the following is an example of objective data? A. Chief problem B. Laboratory results C. Medical history of patient D. Review of body systems

B. Laboratory results

A patient who has rheumatoid arthritis is scheduled to start taking celecoxib [Celebrex]. Which condition, if found in the patient's medical record, would prompt the nurse to hold the medication and consult with the prescribing provider? a) Hypothyroidism b) Allergy to penicillin c) Recent heart bypass surgery d) Positive tuberculin skin test result

C Celecoxib [Celebrex] should be avoided in patients who have undergone recent heart bypass surgery. Because it does not inhibit COX-1, platelet aggregation is not suppressed. It does inhibit COX-2 in blood vessels, which results in increased vasoconstriction. Unimpeded platelet aggregation and increased vasoconstriction pose a higher risk of thrombotic events in patients with certain cardiovascular risk factors. Hypothyroidism, a penicillin allergy, and a positive tuberculin skin test result are not contraindications to taking celecoxib [Celebrex].

The nurse assesses a patient who takes ibuprofen [Advil] on a regular basis. Which finding in the patient would prompt the nurse to contact the healthcare provider immediately? a) jaundice b) drowsiness c) hematemesis d) dysmenorrhea

C Ibuprofen is a member of the nonaspirin, first-generation nonsteroidal anti-inflammatory drugs (NSAIDs). Through inhibition of cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), ibuprofen poses a risk for gastric ulceration and bleeding, which may lead to hematemesis. Ibuprofen is used to reduce inflammation, fever, and pain and therefore is effective in reducing dysmenorrhea (painful menstrual cramping). It is not known to cause drowsiness or jaundice.

The nurse should include which statement(s) when teaching a patient about the use of acetaminophen [Tylenol]? Select all that apply. a) "Use of this drug can prevent heart attack and stroke." b) "The most common side effect of treatment with this drug is kidney failure." c) "Do not routinely use acetaminophen to prevent vaccine-associated fever and pain." d) "Notify your healthcare provider if you notice that your skin or eyes are turning yellow." e) "Acetaminophen is a useful drug for the treatment of inflammation such as rheumatoid arthritis."

C,D Acetaminophen [Tylenol] is used to treat fever and pain. It is not an antiinflammatory drug. The most serious side effect of acetaminophen therapy is liver failure; therefore, the healthcare provider should be notified if indications of jaundice are seen, such as yellowing of the skin or sclera. Acetaminophen therapy has no antiplatelet activity; therefore, it is not used to prevent heart attack or stroke. Routine use of acetaminophen may blunt the immune response to vaccines; therefore, it should be avoided as routine treatment for vaccine-associated fever and pain.

When assessing older adults and those with renal dysfunction, the nurse would expect the creatinine* clearance to be which of the following? A. substantially increased. B. slightly increased. C. decreased. D.in the normal range.

C. decreased. * filtered through the kidney and excreted in urine. Doctors measure the creatinine level as a test of kidney function.

Adverse reactions and drug interactions occur frequently in older adults due to all of the following except A. consumption of numerous drugs owing to multiple chronic illnesses. B. drugs ordered by several health care providers. C. increased incidence of allergic responses. D. self-medication with OTC preparations.

C. increased incidence of allergic responses.

What is the primary site of metabolism for most drugs? A. kidney. B. small intestine. C. liver. D. brain.

C. liver.

Before information about drug therapy is presented to a patient, it is most important for the nurse to: A.determine the patient's reading level. B.plan the number of teaching sessions. C.assess the patient's readiness to learn. D.tell the patient that he or she must comply with the drug therapy.

C.assess the patient's readiness to learn.

Older adults are at risk for taking many medications together. This is known as: A.tachyphylaxis. B.drug interaction. C.polypharmacy. D.tolerance.

C.polypharmacy. •Rationale: Polypharmacy is taking many medications together.

Before administering a medication, the nurse checks a drug reference book or pamphlet to obtain pertinent data. Which data should the nurse note?

Contradictions, half life, protein binding effect, therapeutic range

What is the drug class of prednisone?

Corticosteroids

patient with a history of stroke and myocardial infarction (MI) is on a daily aspirin regimen. Which of the following would alert the nurse to contact the primary healthcare provider? a) temperature 97.9 F b) heart rate 99 beats/min c) blood glucose level 78 mg/dL d) blood pressure 160/94 mm Hg

D An elevated blood pressure over 150/90 mm Hg puts the patient at a greater risk for hemorrhagic stroke.

Before administering celecoxib [Celebrex], it is most important for the nurse to assess the patient for which condition? a) Hypothyroidism b) Diabetes mellitus c) A history of hepatitis C d) An allergy to sulfonamides

D Celecoxib contains a sulfur molecule and therefore can precipitate an allergic reaction in patients allergic to sulfonamides. Accordingly, the drug should be avoided by patients with a sulfa allergy. Hypothyroidism, diabetes mellitus, and hepatitis C should be part of the nurse's assessment but are not the most important.

Which assessment finding indicates that the nonsteroidal anti-inflammatory drug has been effective? a) PTT is 100 seconds. b) Patient's bleeding time is prolonged. c) Patient has increased circulation to his legs. d) Pain has decreased from a 6 to a 1 on a scale of 10.

D Prostaglandins are produced in response to activation of the arachidonic acid pathway. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen work by blocking cyclooxygenase, the enzyme responsible for conversion of arachidonic acid into prostaglandins. Decreasing the synthesis of prostaglandins results in decreased pain and inflammation. The length of the PTT, the bleeding time, and the increased extremity circulation are not therapeutic effects of the medication.

A patient who takes daily aspirin for stroke risk and nabumetone [Relafen] for arthritis is concerned after reading that aspirin should not be taken with other nonsteroidal antiinflammatory drugs. What is the nurse's best response to the patient? a) "You are correct; you shouldn't take aspirin." b) "You should take Tylenol instead of aspirin." c) "Ask your provider to increase your dose of Relafen." d) "Take an aspirin every day even though you are on Relafen."

D Relafen inhibits COX-2 and does not inhibit platelet aggregation. Patients at risk for stroke or heart attack who take aspirin to prevent blood clotting (decrease platelet aggregation) would not benefit from COX-2 inhibitors. The nurse should not reinforce the patient's erroneous ideas about the medication. Tylenol does not inhibit platelet aggregation, so it would not be an adequate substitute for aspirin. Increasing the dose of Relafen will not change the action.

A patient is brought to the emergency department with a history of an overdose of acetaminophen. The health care team starts treatment, involving various protocols to prevent possible toxicity. What measures should be taken to reverse the toxic effects of the drug? Select all that apply. a. Obtain blood work. b. Administer anesthesia. c. Ensure a patent airway. d. Administer acetylcysteine. e. Administer activated charcoal. f. Administer intravenous calcium.

a, c, d, e In a case of drug overdose and possible toxicity, the first priority would be preservation of vital functions such as the airway and circulation. Administration of activated charcoal prevents further absorption of the drug into the blood. Blood work should be obtained to determine the concentration of the drug present in the blood, and the antidote acetylcysteine should be administered. Anesthesia does not serve any purpose in reducing drug toxicity. Intravenous calcium maybe administered when there is an overdose of calcium channel blockers.

A patient is prescribed an enteric-coated preparation to prevent stomach irritation related to a drug. What should the nurse advise this patient regarding administration of an enteric-coated preparation? Select all that apply. a. Anticholinergic drugs may negate the effect of the enteric coating. b. The enteric-coated drugs should be crushed before administration. c. The enteric coating prevents absorption of the drug in the intestine. d. The enteric coating prevents dissolution of the drug in the stomach. e. The enteric-coated drugs should be taken with large amounts of food.

a, d Anticholinergic drugs reduce gastric transit time and may result in dissolution of the drug in the stomach itself. Therefore, enteric-coated tablets should not be taken with anticholinergic drugs. Enteric-coated tablets are resistant to dissolution in the stomach because of the coating. These tablets should not be crushed, because it hampers the effectiveness of the drug. Enteric-coated tablets dissolve and are absorbed in intestine. Eating a large amount of food may also result in dissolution of the drug in the stomach itself and negate the drug effect.

Medications given orally bypass the portal circulatory system. b. Medications given intravenously are not affected by the first-pass effect. c. Drugs administered intravenously enter the portal system before systemic distribution. d. A large percentage of an intravenously administered drug is metabolized into inactive metabolites in the liver.

b. When drugs with a high first-pass effect are administered orally, a large amount of drug may be metabolized before it reaches the systemic circulation. The same drug given intravenously will bypass the liver. This prevents the first-pass effect from taking place, and therefore more of the drug reaches the circulation. Parenteral doses of drugs with a high first-pass effect are much smaller than oral doses, yet they produce the same pharmacologic response.

A patient has taken a drug orally. If the drug has a high first-pass effect, which statement about the drug is appropriate? a.Formation of active metabolites is high in bile. b.Formation of inactive metabolites is high in feces. c. Formation of inactive metabolites is high in the liver. d. Formation of inactive metabolites is low in the kidneys.

c. Formation of inactive metabolites is high in the liver. The first-pass effect is determined by the levels of active or inactive metabolites of a drug in the liver or blood, not kidneys, after first-pass metabolism. If the drug has a high first-pass effect, the proportion of drug metabolized into inactive metabolites is high in the liver. As a result, a smaller amount of active metabolites will be released into the blood. So, the higher the first-pass effect, the lower the bioavailability of active metabolites. The formation of inactive metabolite is low in the liver and high in feces, indicating that the drug has a low first-pass effect. A drug with low first-pass metabolism will have high active metabolites in bile.
