Which statement by a client warrants further instruction by the nurse about the changing insulin needs of a diabetic client during pregnancy? "Episodes of hypoglycemia are more likely to occur during the first 3 months." "I will increase my insulin dosage by 5 units each month during the first trimester." "Insulin dosage will likely need to be increased during the second and third trimesters." "Breastfeeding will decrease my insulin needs to lower than my prepregnancy levels."

"I will increase my insulin dosage by 5 units each month during the first trimester." Rationale Insulin needs during pregnancy are determined individually according to the client's glucose levels. Insulin needs in the first trimester may actually decrease, so the client's statement about increasing her insulin dose, indicates the need for reteaching.

Which heparin concentration should the nurse use to convert an intravenous site to a heparin lock? 10 units/ml. 100 units/ml. 1000 units/ml. 10,000 units/ml.

100 units/ml. Rationale The concentration of heparin 100 unit/ml is used for flushing and maintaining a heparin lock.

A client asks the nurse to explain the meaning of a narrow therapeutic index of a medication. What information should the nurse use to answer the question? The onset of action for the medication occurs very quickly. A small margin exists between safe and toxic plasma levels. Bioavailability is significantly reduced by the first-pass effect. Minimum dosage is needed for the medication to be effective.

A small margin exists between safe and toxic plasma levels. Rationale A narrow therapeutic index means that there is a narrow difference between safe and toxic drug levels, so clients receiving these medications should be closely monitored.

A school-aged child is taking methylphenidate hydrochloride (Ritalin, Biphentin) for the treatment of attention-deficit hyperactivity disorder (ADHD). The mother tells the nurse that she gives the medication at bedtime so it is "working" during school the next morning. What modification to the administration plan should the nurse recommend to this mother? Continue administering the medication dose at bedtime. Give the medication when the child arrives at school. Take the medication with meals. Administer at least six hours before bedtime.

Administer at least six hours before bedtime. Rationale Central nervous system stimulants, such as Ritalin, should be taken at least six hours before bedtime to decrease insomnia.

Based on the blood culture and sensitivity results, the healthcare provider prescribes an IV aminoglycoside antibiotic and discontinues the current prescription for another broad spectrum antibiotic. The medication administration record indicates that the client received the broad spectrum antibiotic two hours ago. Which action should the nurse implement? Obtain peak and trough serum levels so the aminoglycoside antibiotic can be initiated. Administer the initial dose of the aminoglycoside antibiotic as soon as possible. Withhold antibiotic administration until the healthcare provider clarifies the prescriptions. Schedule the initial dose of the aminoglycoside antibiotic for the following day.

Administer the initial dose of the aminoglycoside antibiotic as soon as possible. Rationale Based on the blood culture and sensitivity results, the prescribed aminoglycoside antibiotic is the most effective in treating the client's infection, so it should be administered as soon as possible.

The nurse should instruct a client to avoid which product while taking carisoprodol (Soma) for muscle spasms? Aspirin products. Antacids. Alcoholic beverages. Dairy products. Submit

Alcoholic beverages. Rationale Soma is a centrally-acting muscle relaxant that can cause CNS depression and can have an additive effect when taken with other CNS depressants, such as alcohol.

Which drug of choice is indicated for acute ventricular dysrhythmias associated with myocardial infarction? Diltiazem.VT dys Bretylium. Amiodarone. Adenosine.

Amiodarone. Rationale Based on the Tachycardia Algorithm, amiodaroneis the drug of choice for acute ventricular dysrhythmias associated with myocardial infarction (C). (B) is not indicated. (A and D) are used for supraventricular tachyarrhythmias.

A client with pneumonia receives a prescription for tetracycline (Sumycin). What precautions should the nurse include in this client's teaching? Take the medication with a glass of orange juice. Avoid over-the-counter medications containing alcohol. Avoid diary products for 2 hours after taking the medication. Do not use teeth whitening agents during the treatment regimen.

Avoid diary products for 2 hours after taking the medication. Rationale Dairy products should not be ingested until at least 2 hours after taking Sumycin because the calcium from the dairy binds with tetracycline and decreases the medication's absorption.

A client who has Trichomonas vaginalis receives a prescription for metronidazole (Flagyl) . Which instruction should the nurse provide during client education? Do not ingest with diary products. Notify the clinic if the urine changes color. Obtain liver function tests every 3 months. Avoid over-the-counter antitussives.

Avoid over-the-counter antitussives. Rationale Flagyl can produce disulfiram (Antabuse)-like the reaction when combined with products containing alcohol, such as over-the-counter cough remedies, so the client should be informed to avoid ingesting any alcohol product during the use of Flagyl.

A client with depression receives a prescription for amitriptyline (Elavil). Which instruction should the nurse include in the client's teaching? Do not ingest foods with tyramine. Avoid the consumption of alcohol. Obtain daily blood pressure readings. Take with a glass of orange juice.

Avoid the consumption of alcohol. Rationale Tricyclic antidepressants (TCAs) such as amitriptyline can cause sedation and should not be mixed with agents that depress the central nervous system, so the client should be instructed to avoid alcohol. The consumption of alcohol and TCAs interaction could worsen the client's depression; increased drunkenness and potentially cause death.

A male client with meningitis is prescribed cefotaxime (Claforan) IV and asks the nurse why he cannot receive an oral drug, such as cefaclor (Ceclor) or cefadroxil (Duricef), that he has taken before for infections. How should the nurse respond when considering the actions of cephalosporins? Cefazolin (Ancef) is another IV antibiotic that can be prescribed. Cefaclor (Ceclor) is a good alternative to suggest to the healthcare provider. Cefadroxil (Duricef) is usually prescribed when the IV is discontinued. Cefotaxime (Claforan) provides therapeutic CNS concentrations. Submit

Cefotaxime (Claforan) provides therapeutic CNS concentrations. Rationale According to research studies, only third generation cephalosporins such as cefotaxime (Claforan), and ceftazidime have been shown effective in treating bacterial meningitis with the exception of cefuroxime, the only second generation cephalosporin shown to be effective. First generation cephalosporins have not been successful in the treatment of bacterial meningitis. IV administration of these antibiotics are preferred route of administration due to oral administration medication levels tend to be too low to be effective in comparison to parental administration.

The nurse should expect the healthcare provider to prescribed what treatment regimen for a client with peptic ulcer caused by Helicobacter pylori ? (Select all that apply.) Clarithromycin (Biaxin). Sulfisoxazole (Gantrisin). Misoprostol (Cytotec). Omeprazole (Prilosec). Metronidazole (Flagyl). Sucralfate (Carafate). Submit

Clarithromycin (Biaxin). Omeprazole (Prilosec). Metronidazole (Flagyl). Rationale Recommended medical treatment for Helicobacter pylori includes the use of at least 2 different antibiotics and a proton pump inhibitor to decrease the incidence of antibiotic resistance.

The nurse should withhold which medication if a client reports nausea, vomiting, and diarrhea. Colchicine (Colchicine). Erythromycin (E-Mycin). Naproxen (Aleve, Naprosyn). Labetolol (Normodyne).

Colchicine (Colchicine). Rationale Nausea, vomiting, and diarrhea are indicators of toxic effects of colchicine which can be life-threatening, and if present, this drug should be withheld and the healthcare provider notified.

A client is taking cyclosporine for renal allograft rejection prevention. After 9 months of drug therapy, the nurse reviews laboratory data and notes that the blood urea nitrogen level is 36 mg/dl. What additional finding should the nurse identify? Hypotension. White blood cell count 10,000. Creatinine 28 mg/dl. Anaphylactic reaction.

Creatinine 28 mg/dl. Rationale Acute organ rejection usually occurs in the first 3 months after transplantation or at any time if an infection develops. Cyclosporine (Sandimmune, Neoral, Gengraf), is a cytokine inhibitor used to prevent and treat organ rejection, which is manifested by elevated blood urea nitrogen (norm 10 to 20 mg/dl) and creatinine (norm 0.6 to 1.2 mg/dl).

A client is admitted for atrial fibrillation, and the healthcare provider prescribes disopyramide (Norpace). After explaining the action of this antidysrhythmic agent, which complaint should the nurse instruct the client to report? Joint pain. Dizziness or muscle weakness. Daily weight gain of 2 pounds. Dry mouth.

Daily weight gain of 2 pounds. Rationale Disopyramide (Norpace) is a Class IA antiarrhythmic (with similar actions as procainamide) used to suppress and prevent premature ventricular contractions, episodes of ventricular tachycardia, atrial flutter, and atrial fibrillation. The nurse should instruct the client to report any sudden weight gain that may indicate fluid retention related to poor cardiac output, which may be the result of ineffective management of the dysrhythmia.

What pathophysiological action supports the expected outcome for a client with chronic cancer pain who is treated with imipramine (Tofranil), a tricyclic antidepressant? Increases pain threshold by stimulating opiate receptors in the CNS to release of endogenous enkephalins. Decreases perception of pain by blocking opiate receptors in the brain and descending inhibitory nerves. Decreases transmission of pain impulses by altering serotonin and norepinephrine activity at nerve synapses. Increases pain tolerance through relief of depression by increasing the amounts of norepinephrine in the brain. Submit

Decreases transmission of pain impulses by altering serotonin and norepinephrine activity at nerve synapses. Rationale Tricyclic antidepressants reduce neuropathic pain due to cancer invasion by blocking the reuptake of serotonin and norepinephrine in the CNS and thereby inhibiting pain transmission in the spinal cord dorsal horn, which are part of the descending pain-modulating system

What action should the nurse implement to provide analgesic titration for a client in pain? Teach the client to increase the time range between doses of pain medication. Monitor the effects of continuous intravenous infusion of narcotic analgesics. Plan with the client how to use a specific total dose of analgesic over a 24-hour period. Determine the optimal analgesic dosage required that causes the least side effects. Submit

Determine the optimal analgesic dosage required that causes the least side effects. Rationale No given dosage of an analgesic provides the same level of pain relief for every patient, and so titration upward or downward is determined based on the client's response, so that the optimal dosage achieves adequate pain relief with minimal side effects for the client. An individual's response to the medication dosage is the assessment for titration, and the titration dose should be implemented as long as analgesia is needed.

A pediatric client who has been diagnosed with partial seizures receives a prescription for topiramate (Topamax). What information should the nurse provide to the child's parents? Do not crush the tablet prior to administration. Give the medication with 8 oz of orange juice. Avoid prolonged exposure to direct sunlight. Administer the tablet an hour before meals.

Do not crush the tablet prior to administration. Rationale The tablet form of topiramate should be taken with adequate fluids and without breaking it because of its extremely bitter taste, so crushing the tablet should be avoided.

A client receives a prescription for sulfamethoxazole-trimethoprim (Septra) for a urinary tract infection (UTI). What instruction should the nurse provide the client? Ingest food prior to taking the antibiotic. Drink at least 8 glasses of water a day. Take the medication with grapefruit juice. Avoid prolonged exposure to sunlight.

Drink at least 8 glasses of water a day. Rationale To decrease the risk of renal damage due to crystalluria associated with sulfamethoxazole, the client should be instructed to consume at least 8 glasses of water a day. To increase absorption, sulfamethoxazole should be given on an empty stomach.

Miotic drug therapy for the treatment of glaucoma is based chiefly upon which physiologic action? Enhancing aqueous humor outflow. Inhibiting aqueous humor production. Maintaining intraocular pressure. Preventing extraocular infection.

Enhancing aqueous humor outflow. Rationale Miotic drugs act to enhance aqueous outflow through papillary constriction with the goal to reduce intraocular pressure.

A 48-year-old client is experiencing a severe anaphylactic reaction to an injection of contrast media. What pharmacologic agent is of greatest use in this situation? Dopamine (Intropin). Loratadine (Claritin). Nitroprusside (Nipride). Epinephrine (Adrenalin).

Epinephrine (Adrenalin). Rationale Epinephrine is the drug of choice in treating hypotension and circulatory failure associated with anaphylaxis because it is a potent vasoconstrictor. An anaphylactic reaction is an acute systemic hypersensitivity reaction that occurs within minutes of antigen exposure (such as with contrast material containing iodine) that can result in peripheral vascular collapse.

The healthcare provider prescribes a medication for an older adult client who is complaining of insomnia, and instructs the client to return in two weeks. The nurse should question which prescription? Zolpidem (Ambien) 10 milligrams orally at bedtime. Eszopiclone (Lunesta) 10 milligrams orally at bedtime. Temazepam (Restoril) 7.5 milligrams orally at bedtime. Ramelteon (Rozerem) 8 milligrams orally at bedtime.

Eszopiclone (Lunesta) 10 milligrams orally at bedtime. Rationale The prescription for eszopiclone (Lunesta) 10mg at bedtime is too high for this client. The dosing of this medication is usually a client is started off at 1mg at bedtime and may advance up to 3mg maximum if needed.

The therapeutic effect of insulin in treating Type 1 diabetes mellitus is based on which physiologic action? Facilitates transport of glucose into the cells. Stimulates function of beta cells in the pancreas. Increases intracellular receptor site sensitivity. Delays carbohydrate digestion and absorption.

Facilitates transport of glucose into the cells. Rationale Glucose moves across the cell membrane by using an active transport mechanism. Insulin acts as the carrier of glucose and is the only hormone that decreases blood glucose levels by facilitating the transport of glucose into the cells.

A client who is receiving chemotherapy is prescribed ondansetron (Zofran). What side effect should the nurse include in the teaching plan? Headache. Dry mouth. Impaired taste. Blurred vision. Submit

Headache. Rationale Ondansetron (Zofran), a serotonin antagonist, is the most effective antiemetic in suppressing nausea and vomiting caused by cancer chemotherapy-induced emesis or emetogenic anticancer drugs. Common side effects include headache, diarrhea, dizziness, and fatigue.

A client receives a prescription for esomeprazole (Nexium) for heartburn. Which finding in the client's history should the nurse report to the healthcare provider before administering the prescription? Eats spicy food three times a week. History of deep vein thrombosis. Drinks 2 alcoholic beverages on weekends. Family history of diabetes mellitus.

History of deep vein thrombosis. Rationale Esomeprazole (Nexium), a proton pump inhibitor (PPI), may increase the chance of bleeding in a client who is taking both a PPI and warfarin (Coumadin), which is used in the treatment of deep vein thrombosis (DVT). The healthcare provider should be informed of the client's recent history and treatment for DVT prior to giving Nexium.

An older client is taking warfarin sodium (Coumadin) PO 2.5 mg twice a day. Which laboratory value should the nurse identify as a therapeutic response of the medication? INR of 2 to 3. PT of 4 seconds. PTT of 20 seconds. aPTT of 3 times normal.

INR of 2 to 3. Rationale Recommended INR ranges for clients on warfarin therapy is 2 to 3. Therapeutic anticoagulation using Coumadin should prolong the prothrombin time (PT) by 1.5 to 2 times the control value (a normal value is 10-20 seconds), (or 20% to 30% of the normal value, if percentages are used).

What is the effect of beta-blocking agents when used for treatment of glaucoma? Inhibiting aqueous humor production. Enhancing aqueous humor outflow. Increasing intraocular pressure. Preventing extraocular infection.

Inhibiting aqueous humor production. Rationale Beta-blockers are used to inhibit aqueous humor production, with the goal is to reducing intraocular pressure.

When assessing a client prior to the administration of digoxin (Lanoxin, APO-Digoxin), which data is most important for the nurse to consider? Presence of a grade 2 murmur. Nailbed capillary refill of 5 seconds. Irregular apical pulse with a rate of 87. Bilateral lower extremity dependent rubor.

Irregular apical pulse with a rate of 87. Rationale The action of digoxin is to slow the heart rate and strengthen the force of contraction, so it is essential for the nurse to auscultate the apical pulse for a full minute and that the apical pulse is grater then 60 beats per minute for an adult or greater then 90 beats per minute for an infant prior to administration. If apical pulse is below the desired parameters, hold the dose and recheck the rate in one hour.

A client with rheumatoid arthritis is receiving a prescription for minocycline (Minocin). Which side effect is most important for the nurse to instruct the client to report? Loss of balance and dizziness. Nausea and vomiting. Headache and mouth sores. Abdominal pain and diarrhea.

Loss of balance and dizziness. Rationale Minocycline (Minocin), a tetracycline antibiotic, is used to treat mild cases of rheumatoid arthritis and can cause damage to the vestibular part of the inner ear, so the client should report dizziness or difficulty maintaining balance.

When prescribed for a client with hepatic encephalopathy, what is the therapeutic action of lactulose (Portalac)? Lowers the pH of the colon. Softens the stool. Increases glucose absorption. Stimulates peristalsis.

Lowers the pH of the colon. Rationale Colonic bacteria digest lactulose to create a drug-induced acidic and hyperosmotic environment that draws water and blood ammonia into the colon. The physiologic action of lactulose for the client with hepatic encephalopathy is to lower the pH of the colon which inhibits diffusion of ammonia into the bloodstream.

A 38-year-old gravida 2 para 2 is diagnosed with bacterial vaginosis 9-months postpartum. A prescription is written for metronidazole (Flagyl). Which information is most important for the nurse to obtain from the client before initiating treatment? Sexual history. Use of oral contraceptives. Method of infant feeding. Possibility of pregnancy.

Method of infant feeding. Rationale Flagyl is contraindicated if the woman is breastfeeding because high concentrations have been found in breast milk fed to infants. If Flagyl must be prescribed, the woman should be instructed to pump and discard the milk during treatment and for 48 to 72 hours after the last dose.

Which side effects should the nurse monitor for a client who is receiving dexamethasone (Decadron) following neurosurgery? (Select all that apply.) Mood swings. Decreased appetite. Increased weight gain. Serum glucose level of 65 mg/dl. Delayed incisional wound healing. Serum hemoglobin level of 9 mg/dl. Submit

Mood swings increased weight gain delayed incisional would healing serum hemoglobin level of 9 mg/dl Rationale Dexamethasone (Decadron) is a long-acting glucocorticoid prescribed for neurosurgical procedures because it suppresses inflammation and has a low sodium-retaining ability, which is important in averting cerebral edema. However though the medication does produce the following side effects such as: mood swings; an increase in appetite, resulting in weight gain; hyperglycemia (serum glucose level above 120 mg/dl) which is related to the gluconeogenesis properties of corticosteroids; delayed in wound healing related to immune suppression properties; and complete blood count resulting in a decreased in WBC and hemoglobin (less than 12mg/dl). When a client is receiving dexamethasone, they should be monitor for these side effects.

The nurse administers the initial dose of a fentanyl (Duragesic) transdermal patch to a client with chronic pain. When monitoring the client an hour later, which assessment is most important for the nurse to obtain? Level of consciousness. Moistness of mucosa. Bowel sound activity. Numeric pain scale.

Numeric pain scale. Rationale Transdermal fentanyl, an opioid analgesic, has an onset and peak of 6 to 12 hours after the initial dose, so it is most important to determine the client's level of pain, which can persist as breakthrough pain throughout the 72-hour duration of the patch.

A client with Paget's disease is started on calcitonin (Calcimar) 500 mcg subcutaneously daily. During the initial treatment, what is the priority nursing action? Assess the injection site for inflammation. Evaluate the client's level of pain. Monitor the client's alkaline phosphatase levels. Observe the client for signs of hypersensitivity.

Observe the client for signs of hypersensitivity. Rationale Calcitonin is given to a client with Paget's disease to lower serum calcium levels. The nurse's highest priority is to observe for signs of hypersensitivity, such as skin rash, hives, or anaphylaxis. Upon initiation of treatment, emergency equipment should be readily available.

Which route should the nurse clarify with the healthcare provider prior to administering a drug with a high first-pass effect? Oral. Buccal. Sublingual. Intravenous.

Oral The first-pass effect occurs when hepatic metabolism decreases the bioavailability of a drug. Oral forms of medications are processed through the GI tract, absorbed through the small intestines, and undergo the first-pass effect in the liver in which some of the active ingredients is removed from the drug before it reaches the intended site of action. Rationale The first-pass effect occurs when hepatic metabolism decreases the bioavailability of a drug. Oral forms of medications are processed through the GI tract, absorbed through the small intestines, and undergo the first-pass effect in the liver in which some of the active ingredients is removed from the drug before it reaches the intended site of action.

A client receives a new prescription for nitroglycerin (Nitrostat) tablets. Which instruction should the nurse include in this client's teaching? Take the medication at least an hour before every meal. Monitor your pulse for 60 seconds before administration. Place under the tongue as needed every 5 minutes up to 3 times. Resume normal activities after chest pain relief is obtained.

Place under the tongue as needed every 5 minutes up to 3 times. Rationale The client should be instructed to place a tablet under the tongue every 5 minutes up to 3 times, and call 911 if the anginal pain is not relieved after the third tablet. Nitrostat tablets should be taken sublingually (SL), under the tongue, to avoid first-pass effect, and be taken at the onset of chest pain without delay to expedite oxygen flow to myocardial tissues.

The healthcare provider has prescribed digoxin for a client who has been taking furosemide (Lasix) for six months. What laboratory serum levels should the nurse review before administering the digoxin? Calcium. Magnesium. Potassium. Furosemide.

Potassium. Rationale The client's serum potassium levels should be evaluated before giving the first dose of digoxin because Lasix is can cause hypokalemia which increases the risk of digoxin toxicity and cardiac arrhythmias.

A client is taking danazol (Danocrine) for endometriosis and calls the clinic nurse to complain of a dark, swollen, and painful leg. What instructions should the nurse provide the client? Wear support stockings. Elevate both legs and apply heat. Proceed to the closest emergency room. Walk for 20 to 30 minutes to reduce muscle cramps. Submit

Proceed to the closest emergency room. Rationale A dark, swollen, and painful leg is consistent with deep vein thrombosis (DVT), an adverse effect of danazol, so the client should be instructed to seek immediate emergency care.

What is the expected outcome of esomeprazole (Nexium) when prescribed for a client with gastroesophageal reflux disease (GERD)? Promotion of rapid tissue healing. Increased gastric emptying. Improved esophageal peristalsis. Neutralization of gastric secretions.

Promotion of rapid tissue healing. Rationale Proton pump inhibitors, such as esomeprazole (Nexium), act to inhibit gastric acid secretion and promote rapid healing of esophageal tissue.

A client is taking sulfisoxazole (Gantrisin) for a urinary tract infection (UTI) and complains of nausea and gastric upset since starting the medication. Which additional adverse reaction should the nurse instruct the client to report? Rash. Diarrhea. Hematuria. Muscle cramping. Submit

Rash. Rationale Side effects of sulfisoxazole (Gantrisin), a sulfonamide antibiotic, include possible allergic response, manifested by skin rash and itching, which can progress to Stevens-Johnson syndrome - erythema multiforme, a severe hypersensitivity reaction. Other gastrointestinal disturbances, such as diarrhea, crystalluria and photosensitivity are other side effects that commonly occur with "sulfa" agents, but do not indicate a discontinuation of the prescription.

A client with chronic gouty arthritis takes allopurinol (Zyloprim) and experiences an acute attack of gouty arthritis. The healthcare provider prescribes concurrent low-dose colchicine. What information should the nurse provide the client that best explains the action of the colchicine? Acts like aspirin to relieve pain. Facilitates the excretion of uric acid. Reduces inflammation at the affected site. Prevents formation of uric acid crystals.

Reduces inflammation at the affected site. Rationale Allopurinol (Zyloprim) improves joint function in chronic gouty arthritis by reducing blood uric acid levels to prevent and promote regression of tophi. Low-dose colchicine, an anti-inflammatory agent specific for gout, is used concurrently with allopurinol, which can precipitate an incident of acute gouty arthritis.

A client receives a new prescription for an angiotensin-converting enzyme (ACE) inhibitor. What client history contraindicates its use? Asthma. Heart failure. Renal artery stenosis. Coronary artery disease.

Renal artery stenosis. Rationale Angiotensin-converting enzyme (ACE) inhibitors can cause severe renal insufficiency in clients with bilateral renal artery stenosis or stenosis in the artery to a single remaining kidney.

A resident of a long-term care facility is taking lithium carbonate (Eskalith) to treat bipolar disorder. Which instruction should the nurse provide to this client's caregivers? Offer the morning dose of the medicine before breakfast. Have the client chew the pill if it is difficult to swallow. Encourage high energy fluid intake by providing sports drinks or sodas. Report symptoms of hypothyroidism such as fatigue and constipation.

Report symptoms of hypothyroidism such as fatigue and constipation. Rationale Lithium carbonate (Eskalith) causes hypothyroidism in 1 to 4% of those clients receiving the medication, so caregivers should assess for signs of hypothyroidism, including fatigue and constipation (early signs) and myxedema or goiter (late symptoms).

A client receives a new prescription for pentazocine (Talwin), a mixed opioid agonist-antagonist after an opioid agonist is discontinued. What is the advantage for the client when the new prescription is implemented? Tolerance does not occur. Less agitation is experienced. The analgesic ceiling is higher. Respiratory depression is less.

Respiratory depression is less. Rationale Mixed agonist-antagonists bind as an agonist at the Kappa receptor and as antagonists or partial agonists on the mu receptor, which produces less respiratory depression than opioid agonists that are pure mu agonists.

The nurse receives a unit of blood from the blood bank for a postoperative client who is currently in the X-ray department. What action should the nurse implement? Return the blood to the blood bank for refrigeration within 30 minutes. Hang the blood transfusion as soon as the client returns to the unit. Store the blood bag in the nursing unit's refrigerator until the client returns. Take the unit of blood to the X-ray department to initiate the transfusion.

Return the blood to the blood bank for refrigeration within 30 minutes. Rationale A blood transfusion should be hung for administration within 30 minutes of its arrival from the blood bank. If it is not going to be used within that time frame, it must be returned to the blood bank for refrigeration. Waiting until the client returns to the unit is unpredictable, and the delay to hang the blood within 30 minutes can contribute to contamination and infection.

The nurse is providing medication teaching for a client who has recently received a prescription for clozapine (Clozaril). Which instruction should be included in this client's teaching plan? Avoid prolonged sun exposure. Rise slowly from a lying position. Do not eat any aged cheese. Take as needed for anxiety.

Rise slowly from a lying position Rationale Orthostatic hypotension is a side effect of Clozaril, so the client should be instructed to rise slowly from a lying down or sitting position.

A client who takes a statin and gemfibrozil (Lopid) for hyperlipidemia reports onset of muscle pain and weakness. What additional assessment is most important for the nurse to obtain? Serum liver enzymes. T3 and T4 blood levels. Bowel function. Peripheral sensation.

Serum liver enzymes. Rationale Concomminent use of gemfibrozil and statins can cause muscle weakness and wasting known as myopathy, which is reflected in serum liver function enzymes, such as elevated serum aspartate aminotransferase (AST or SGOT) that is also found in skeletal muscle.

An emergency department triage nurse is interviewing a female client who has a history of epilepsy with tonic-clonic seizures controlled by phenytoin (Dilantin). Which information is most significant in planning this client's care? She has missed 2 menstrual periods. She has had no dental care for several years. She ran out of her medication 4 days ago. She has smoked 3 packs of cigarettes a day for 10 years. Submit

She ran out of her medication 4 days ago. Rationale Abruptly stopping anticonvulsant medications can precipitate seizures or the development of status epilepticus. Immediate seizure precautions and medication administration are necessary.

A client at 30-weeks gestation is in preterm labor. The healthcare provider prescribes two 12-mg doses of betamethasone (Celestone) intramuscularly every 12 hours. The client asks the nurse why she is receiving the Celestone. What information should the nurse use to explain the action of the medication? Suppresses uterine contractions. Stimulates fetal surfactant production. Reduces maternal and fetal tachycardia associated with terbutaline (Brethine) administration. Maintains adequate maternal respiratory effort and ventilation with magnesium administration.

Stimulates fetal surfactant production. Rationale Antenatal glucocorticoids, such as betamethasone (Celestone), are given IM to the mother to stimulate surfactant production in the fetus and accelerate fetal lung maturity, in the event the fetus is delivered prematurely to minimize respiratory distress syndrome associated with premature infants.

A client calls the clinic and states that she forgot to take her oral contraceptives for the past two days. Which instruction is best for the nurse to provide to this client? Take 2 pills a day for 2 days and use an alternate method of contraception for 7 days. Quit the pills for this cycle, use an alternate method of contraception, and resume pills on the fifth day of menstruation. Take one extra pill per day for the rest of this cycle, then resume taking pills as usual next cycle. Take 4 pills now and use an alternate method of contraception for the rest of this cycle.

Take 2 pills a day for 2 days and use an alternate method of contraception for 7 days. Rationale If two pills are missed in a roll, the client should take 2 pills a day for two days and used an alternative form of birth control for seven days.

A client is diagnosed with peptic ulcer disease and receives a prescription for esomeprazole (Nexium) 20 mg capsule daily. When providing this client with discharge teaching, the nurse should include which instruction? Drink fluids between meals to relieve gastric distress. Monitor for an increase in blood pressure during therapy. Dissolve capsule contents in fruit juice for easier ingestion. Take at same time each day one hour before eating a meal.

Take it at the same time each day one hour before eating a meal. Rationale Nexium, a proton pump inhibitor (PPI), is a first-line agent for symptomatic GERD that poorly responds to other acid-reducing drugs, such as H2 antagonists. Nexium is most effective when taken 30 to 60 minutes before a meal.

The healthcare provider prescribes pyridostigmine bromide (Mestinon) tablets for a client with myasthenia gravis (MG). What instruction should the nurse provide this client? Increase activity in the afternoon when the medication is most effective. Take the medication 30 to 45 minutes before eating. Use a PRN dose for increasing muscular weakness or fasciculations. Give the client a dietary guide that describes low-protein foods.

Take the medication 30 to 45 minutes before eating. Rationale Mestinon, an acetylcholinesterase inhibitor, increases the amount of neuromuscular transmitters to promote muscular strength and swallowing, so the client should take the medication at least 30 minutes before meals.

A client who is recently diagnosed with myasthenia gravis received a prescription for pyridostigmine (Mestinon), a cholinergic agent. Which information should the nurse instruct the client to implement when taking this medication? Always take it with meals to avoid gastrointestinal distress. Plan the doses close together for maximal therapeutic effect. Take the medication at least 30 minutes before eating meals. Avoid dairy products two hours before and after taking medications.

Take the medication at least 30 minutes before eating meals. Rationale The nurse should instruct the client to take the medication 30 minutes before meals with an empty stomach, which allows for the onset of action and therapeutic effects to be present during the meal to help improve swallowing and chewing. The doses should also be spaced evenly apart to optimize the effects of the medication.

A client with chronic pancreatitis receives a new prescription for pancrelipase (Pancrease). Which instruction is most important for the nurse to include in this client's teaching? Avoid prolonged exposure to direct sunlight. Stay away from products containing alcohol. Ingest 8 oz of grapefruit juice with the medication. Take the medication when consuming food.

Take the medication when consuming food. Rationale With the loss of exocrine function for a client with chronic pancreatitis, replacement of pancreatic enzymes using pancrelipase (Pancrease) becomes necessary. Diarrhea and steatorrhea (fatty stools) indicate insufficient pancreatic enzymes are present to digest dietary fats and other of nutrients, so pancrelipase, a fat-digesting enzyme, should be consumed with any type of food.

What teaching should the nurse provide a client who has received a new prescription for sildenafil (Viagra)? (Select all that apply.) Frequent use can lead to the development of hypertension. Most effective if taken after at least 6 hours of REM sleep. Take within 30 to 60 minutes of sexual stimulation. Report rebound priapism that occurs for 4 hours or more. Can cause facial flushing and headache.

Take within 30 to 60 minutes of sexual stimulation. Report rebound priapism that occurs for 4 hours or more. Can cause facial flushing and headache. Rationale Sildenafil (Viagra) enhances the natural response to sexual stimuli, so a client should be instructed to take Viagra within 30 to 60 minutes before sexual intercourse to provide adequate time to enhance penile erection. Sildenafil does not cause erection directly, but priapism can occur and should be reported to the healthcare provider if it persists. Common side effects include headaches, facial flushing, and diarrhea. Viagra can potentiate vasodilators, such as alpha-adrenergic blockers, nitroglycerin, and other nitrates used for angina pectoris, and may cause hypotension, which decreases perfusion to vital organs.

The healthcare provider discontinues prednisone, a glucocorticoid, for a client with chronic obstructive pulmonary disease. What instructions should the nurse give the client about the regimen to follow? Life-long treatment is common for chronic disease. The drug should be stopped immediately if no longer needed. The dose must be tapered over the course of 7 to 10 days. Another glucocorticoid should be used to prevent cross-tolerance.

The dose must be tapered over the course of 7 to 10 days. Rationale To minimize the impact of adrenal insufficiency, withdrawal of exogenous glucocorticoids should be done by gradually decreasing the dosage over several days because it can cause life-threatening adrenal insufficiency if abruptly terminated.

The healthcare provider prescribes oral antifungal therapy for a client with onychomycosis. What information should the nurse tell the client? A single dose of the oral antifungal agent is usually sufficient to treat the infection. The infection is difficult to eradicate and requires prolonged therapy for 3 to 6 months. Complete eradicate is important because of the risk of a systemic infection. Prolonged therapy provides no benefit and increases the risk of adverse effects.

The infection is difficult to eradicate and requires prolonged therapy for 3 to 6 months. Rationale Treatment of onychomycosis, a fungal infection of the fingernails and toenails, is difficult to treat and requires prolonged therapy of 3 to 6 months for oral antifungal therapy.

The mother of a newborn asks the nurse why her infant needs the vitamin K (AquaMEPHYTON) injection. What information should the nurse provide? Bacteria that synthesize vitamin K are not present in the newborn's intestinal tract. Oral vitamin K impedes the synthesis of clotting factors in the liver. The maternal diet is often deficient in vitamin K, so the infant is deficient in the vitamin.aquamephyton The synthesis of vitamin K is inadequate for 3 to 4 months in the newborn.

The synthesis of vitamin K is inadequate for 3 to 4 months in the newborn. Rationale Vitamin K is provided due to the fact the newborn does not have the intestinal flora to synthesize adequate vitamin K in the intestines at birth and vitamin K levels in breast milk are considered inadequate for the first 2-3 days of life. Vitamin K promotes the formation of clotting factors in the liver and is routinely given by injection to prevent or treat hemorrhagic disease in the newborn.

Which findings should the nurse identify in an adult client with possible chronic salicylate intoxication? Tinnitus and hearing loss. Photosensitivity and nervousness. Acute gastrointestinal bleeding and anorexia. Hyperventilation and central nervous system effects. Submit

Tinnitus and hearing loss. Rationale The most frequent manifestations of chronic salicylate intoxication in adults are tinnitus and hearing loss.

A male client who is in the terminal stage of cancer is cared for at home by his family and receives a prescription for morphine at a rate to control intractable pain. When the hospice nurse visits, the client awakens, moans in severe pain, and asks for an increase in the morphine dosage. After determining the client's respirations are 10 per minute, what is the best action for the nurse to implement? Titrate the morphine dose upward until the client has adequate pain relief. Suggest to the family that they can also give the client ibuprofen, a non-narcotic analgesic. Hold additional morphine until the client's respirations are at least 16 per minute. Inform the client that an increased dose of morphine increases side effects without additional pain control.

Titrate the morphine dose upward until the client has adequate pain relief. Rationale Tolerance can occur in a client who requires large doses of opioids for intractable pain management, and an increased titration of the analgesic or an additional drug in the same or a different classification may provide more effective pain management. The client's basic need for comfort during the last stages of a terminal malignancy is the main priority for this hospice client.

A client with chronic schizophrenia illness is admitted after taking risperidone (Risperdal) 10 mg/day for three months. The nurse implements a daily assessment using the Abnormal Involuntary Movement Scale (AIMS). What findings should the nurse report to the healthcare provider? Cogwheel rigidity. Drowsiness and dizziness. Tremors and muscle twitching. Dry mouth, constipation, and blurred vision.

Tremors and muscle twitching. Rationale For a client with chronic mental illness, evidence-based pharmacological guidelines recommend first-line treatment using an atypical antipsychotic, such as risperidone (Risperdal), which can cause extrapyramidal symptoms (EPS) at dosages above 10 mg/day. The AIMS criteria measures tardive dyskinesia movements, such as facial, oral, tongue, teeth, and other akinesias of the trunk and extremity, such as tremors and muscle twitching, which should be reported.

A client is receiving fentanyl via an epidural infusion. Which side effect should the nurse anticipate in the first 24 hours of epidural analgesia? Headache. Agitation. Urinary retention. Abdominal cramping and diarrhea.

Urinary retention Rationale Anticipated common side effects of epidural opioids include nausea, itching, and urinary retention which may require urinary catheterization.

A female client receives a prescription for cefadroxil (Duricef) for a urinary tract infection. The client informs the nurse that she is currently taking oral contraceptives (OCP). What information is important for the nurse to share with the client? The antibiotic may be less effective while taking OCP. The medication combination potentiates the risk of adverse reactions. Avoid prolonged sun exposure while taking the antibiotic. Use an additional form of contraception until your menstrual cycle.

Use an additional form of contraception until your menstrual cycle. Rationale Cephalosporins such as cefadroxil can decrease the efficacy of oral contraceptives, so the client should be instructed to use an additional form of contraception.

Which common side effect should the nurse alert a female client about when medroxyprogesterone (Depo-Provera) is prescribed Leg or calf pain. Headaches or visual changes. Vaginal bleeding after discontinuing the medication. Jaundice during the first 3 weeks of administration.

Vaginal bleeding after discontinuing the medication. Rationale Approximately 3 to 7 days after the last cyclic dose of medroxyprogesterone, a female client may experience withdrawal vaginal bleeding.

A client who is diagnosed with methillicin-resistant Staphylococcus aureus receives a prescription for vancomycin (Vancocin). Which assessment should the nurse perform to identify a potential adverse effect? Whisper test. Romberg test. Tactile discrimination. Skin turgor.

Whisper test. Rationale The most serious adverse effect of vancomycin is ototoxicity, which often causes irreversible, permanent impairment. So, a whisper test determines the presence of early hearing impairment.

A client is beginning therapy with montelukast (Singulair) PO 10 mg once a day in the evening. The client asks the nurse, "When should I begin to feel better?" How should the nurse respond? Immediately. Within 24 hours. In about 12 hours. 30 minutes to 1 hour.

Within 24 hours. Rationale Maximal effects of montelukast (Singulair) develop within 24 hours after initiating the first dose.

A client receives a new prescription for ciprofloxacin (Cipro), a synthetic quinolone. When teaching about this drug, which information in the client's history requires special emphasis by the nurse? Snacks on dairy products such as yogurt or ice cream. Previously had a mild allergic reaction to a cephalosporin. Consumes alcoholic drinks occasionally on the weekends. Works twenty hours a week as a lifeguard at the local pool.

Works twenty hours a week as a lifeguard at the local pool. Rationale Cipro can cause both dizziness and photosensitivity. Since the client works as a lifeguard outdoors, measures related to these adverse effects should be addressed.
