The nurse administers 30 mL of lactulose for a client with stage 2 hepatic encephalopathy. Which assessment finding would indicate the medication is being therapeuitc? a. A decrease in blood ammonia levels. b. A softening in the stools. c. An increase in glucose absorption. d. A suppression of gut acidification.

a. A decrease in blood ammonia levels. 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.

The mother of a newborn refuses to have her newborn administer the vitamin K injection. Which information should the nurse provide the mother? a. Bacteria that synthesize vitamin K are not present in the newborn's intestinal tract. b. Oral vitamin K impedes the synthesis of clotting factors in the liver. c. The maternal diet is often deficient in vitamin K, so the newborn is deficient in the vitamin K. d. The synthesis of vitamin K is inadequate for 3 to 4 months in the newborn.

a. Bacteria that synthesize vitamin K are not present in the newborn's intestinal tract. 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 prevention or treat hemorrhagic disease in the newborn.

A client is diagnosed with peptic ulcer disease caused by Helicobacter pylori. Which medications should the nurse anticipate the healthcare provider to prescribe for the client?

a. INR of 2 to 3. 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).

The nurse is teaching a client who is newly diagnosed with Type 1 diabetes about neutral protamine Hagedor (NPH) insulin. Which statement by the client indicates an understanding of how the medication works? a. It facilitates the transport of glucose into the cells. b. It stimulates the function of beta cells in the pancreas. c. It increases the intracellular receptor site sensitivity. d. It delays the carbohydrate digestion and absorption.

a. It facilitates the transport of glucose into the cells. Glucose moves across the cell membrane by using an active transport mechanism. Neutral protamine Hagedor (NPH), also known as isophane insulin, is classified as an intermediate-acting insulin that peaks 4 to 12 hours after the injection and is effective for 12 to 18 hours. The insulin acts as the carrier of glucose and is the only hormone that decreases blood glucose levels by facilitating transport of glucose into the cells.

A nurse is providing medication education for a client prescribed a beta-blocking agents for treatment of glaucoma. Which statement by the client demonstrates an understanding of the mechanism of the medication? a. It inhibits the aqueous humor production. b. It enhances the aqueous humor outflow. c. It increases the intraocular pressure. d. It prevents extraocular infection.

a. It inhibits the aqueous humor production. Beta-blockers are used to inhibit aqueous humor production, with the goal is to reduce intraocular pressure experience by clients diagnosed with glaucoma.

Increased weight gain. d. Serum glucose level of 65 mg/dl. e. Delayed incisional wound healing. f. Serum hemoglobin level of 9 mg/dl.

a. Mood swings. c. Increased weight gain. e. Delayed incisional wound healing. f. Serum hemoglobin level of 9 mg/dl. 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. The medication produces the following side effects: mood swings, increased appetite resulting in weight gain, hyperglycemia (serum glucose level above 120 mg/dL) that is related to the gluconeogenesis properties of corticosteroids, delayed wound healing related to immune suppression properties, and complete blood count resulting in a decreased in WBC and hemoglobin (less than 12 mg/dL). When a client is receiving dexamethasone, they should be monitored for these side effects.

A client experiencing pain from metastatic cancer is prescribed morphine. Which route of administration should the nurse clarify with the healthcare provider prior to administering the medication? a. Oral. b. Buccal. c. Sublingual. d. Intravenous.

a. Oral. Morphine is a drug that has a first-pass effect occurs when hepatic metabolism decreases the bioavailability of a drug. Oral forms of medications are processed through the liver and undergo extensive biotransformation known as the first-pass effect in which some of the active ingredients is removed from the drug before it reaches the intended site of action.

A healthcare provider prescribes cefadroxil (Duricef) for a client with a postoperative infection. It is most important for the nurse to assess for what additional drug allergy before administering this prescription? a. Penicillins. b. Aminoglycosides. c. Erythromycins. d. Sulfonamides.

a. Penicillins. Cross-allergies exist between penicillins and cephalosporins, such as cefadroxil (Duricef), so checking for penicillin allergy is a wise precaution before administering this drug.

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

An end-stage terminally ill client being cared for at home is receiving morphine via a patient-controlled pump for intractable cancer pain. When the hospice nurse visits, the client awakens, moans in severe pain, and asks for an increase in the morphine dosage. The client's heart rate is 80 beats/minute, respirations are 10 breaths/minute, and the blood pressure is 102/68 mmHg. Which is the best action for the nurse to implement? a. Titrate the morphine dose upward until the client has adequate pain relief. b. Suggest to the family that they can also give the client ibuprofen, a non-narcotic analgesic. c. Hold additional morphine until the client's respirations are at least 16 per minute. d. Inform the client that an increased dose of morphine increases side effects without additional pain control.

a. Titrate the morphine dose upward until the client has adequate pain relief. 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 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? a. Whisper test. b. Romberg test. c. Tactile discrimination. d. Skin turgor.

a. Whisper test. 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 prescribed ipratropium reports nausea, blurred vision, headaches, and insomnia after using the inhaler. Which action should the nurse implement first? a. Withhold medication and report symptoms and vital signs to healthcare provider. b. Give PRN medication for nausea and vomiting and evaluate client in 30 minutes. c. Reassure client that the ipratropium given will alleviate the symptoms. d. Delay administration of ipratropium until next maintenance medication is scheduled.

a. Withhold medication and report symptoms and vital signs to healthcare provider. Headache, nausea, blurred vision, and insomnia are symptoms of excessive use of ipratropium. Withholding the medication until the healthcare provider is notified should be initiated to maintain client safety.

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

b. "I will increase my insulin dosage by 5 units each month during the first trimester." 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.

A client prescribed clindamycin hydrochloride intravenously asks the nurse why blood has to be drawn before the third dose and one hour after the completion of the administration of the medication. Which information should the nurse provide the client to answer the question? a. The onset action for the medication occurs very quickly. b. A small margin exists between safe and toxic plasma levels. c. Bioavailability is significantly reduced by the first-pass effect. d. Standard dosage is needed for the medication to be effective.

b. A small margin exists between safe and toxic plasma levels. Clindamycin hydrochloride has a narrow therapeutic index which means there is a narrow difference between safe and toxic drug levels, so clients receiving this medications should be closely monitored. The drawing of the client's blood samples before and one hour after the completion of the administration of the medication is known as a peak and trough level of the medication to monitor the medication's plasma levels in the client's blood.

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? a.

Avoid over-the-counter medications containing alcohol. c. Avoid diary products for 2 hours after taking the medication. d. Do not use teeth whitening agents during the treatment regimen.

c. Avoid diary products for 2 hours after taking the medication. 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 prescribed cyclosporine for the past nine months to prevent renal allograft rejection has a blood urea nitrogen level of 36 mg/dL. Which additional finding should the nurse notify the healthcare provider? a. Hemoglobin level of 16.8 g/dL. b. White blood cell count level of 10,000. c. Creatinine level of 2.8 mg/dL. d. Potassium of 4.2 mEq/L.

c. Creatinine level of 2.8 mg/dL. 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? a. Joint pain. b. Dizziness or muscle weakness. c. Daily weight gain of 2 pounds. d. Dry mouth.

c. Daily weight gain of 2 pounds. 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.

c. Place under the tongue as needed every 5 minutes up to 3 times. 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.

A client being treated with imipramine, an anti-depressant for chronic cancer pain asks the the nurse, "What is the reason for the antidepressant medication?" Which explanation should the nurse provide the client? a. Increases pain threshold by stimulating opiate receptors in the CNS to release of endogenous enkephalins. b. Decreases perception of pain by blocking opiate receptors in the brain and descending inhibitory nerves. c. Decreases transmission of pain impulses by altering serotonin and norepinephrine activity at nerve synapses. d. Increases pain tolerance through relief of depression by increasing the amounts of norepinephrine in the brain.

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

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

c. Irregular apical pulse with a rate of 87. 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 chronic gouty arthritis prescribed allopurinol is experiencing an acute attack of gouty arthritis. The healthcare provider prescribes concurrent low-dose colchicine. Which information should the nurse provide the client that best explains the action of the colchicine? a. It acts like aspirin to relieve pain. b. It facilitates the excretion of uric acid. c. It reduces the inflammation at the affected site. d. It prevents the formation of uric acid crystals.

c. It reduces the inflammation at the affected site. 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 antiinflammatory agent specific for gout, is used concurrently with allopurinol, which can precipitate an incident of acute gouty arthritis.

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? a. Sexual history. b. Use of oral contraceptives. c. Method of infant feeding. d. Possibility of pregnancy.

c. Method of infant feeding. 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.

A client prescribed furosemide for the past six months is scheduled to receive digoxin for heart failure. Which laboratory serum levels should the nurse review before administering the digoxin? a. Calcium. b. Magnesium. c. Potassium. d. Furosemide.

c. Potassium. The client's serum potassium levels should be evaluated before administered digoxin because furosemide can cause hypokalemia which increases the risk of digoxin toxicity and cardiac arrhythmias.

A client prescribed danazol (Danocrine) for endometriosis calls the clinic nurse and reports having a dark, swollen, and painful leg. Which instructions should the nurse provide the client? a. Wear support stockings. b. Elevate both legs and apply heat. c. Proceed to the closest emergency room. d. Walk for 20 to 30 minutes to reduce the pain and edema.

c. Proceed to the closest emergency room. 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.

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

c. Renal artery stenosis. 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.

c. Take within 30 to 60 minutes of sexual stimulation. d. Report rebound priapism that occurs for 4 hours or more. e. Can cause facial flushing and headache. 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.

A client's prescription of prednisone for the management of asthma is to be discontinued. Which information is important for the nurse to give the client? a. The remaining capsules in the medication bottle should be taken until empty. b. The medication should be stopped immediately. c.

c. The dose of the medication should be tapered over the course of 7 to 10 days. 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.

A client prescribed risperidone 10 mg/day for the past three months is being admitted to the hospital. Which physical assessment findings should the nurse report to the healthcare provider? a. Anorexia. b. Drowsiness and lethargy. c. Tremors and muscle twitching. d. Dry mouth, and constipation.

c. Tremors and muscle twitching. For a client with chronic mental illness, evidence-based pharmacological guidelines recommend first-line treatment using an atypical antipsychotic, such as risperidone (Risperdal). Risperidone can cause extrapyramidal symptoms (EPS) with dosages at or above 10 mg/day. Tardive dyskinesia movements, include twitches and uncontrollable movement of the facial, oral, tongue, teeth, and other akinesias of the trunk and extremities, such as tremors and muscle twitching.

The nurse is performing a physical assessment for a client who received fentanyl via an epidural infusion eight hours ago. Which finding should the nurse anticipate? a. Headache. b. Agitation. c. Urinary retention. d. Abdominal cramping and diarrhea.

c. Urinary retention. Anticipated common side effects of epidural opioids within the first 24 hours include nausea, itching, and urinary retention which may require urinary catheterization.

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? a. Cefazolin (Ancef) is another IV antibiotic that can be prescribed. b. Cefaclor (Ceclor) is a good alternative to suggest to the healthcare provider. c. Cefadroxil (Duricef) is usually prescribed when the IV is discontinued. d. Cefotaxime (Claforan) provides therapeutic CNS concentrations.

d. Cefotaxime (Claforan) provides therapeutic CNS concentrations. 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 implement which action to provide analgesic titration for a client in pain? a. Teach the client to increase the time range between doses of pain medication. b. Monitor the effects of continuous intravenous infusion of narcotic analgesics. c. Plan with the client how to use a specific total dose of analgesic over a 24-hour period. d. Determine the optimal analgesic dosage required that causes the least side effects.

d. Determine the optimal analgesic dosage required that causes the least side effects. 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 48-year-old client is experiencing a severe anaphylactic reaction to an injection of contrast media. Which pharmacologic agent is of greatest use in this situation? a. Dopamine (Intropin). b. Loratadine (Claritin). c. Nitroprusside (Nipride). d. Epinephrine (Adrenalin).

d. Epinephrine (Adrenalin). 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.

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? a. Assess the injection site for inflammation. b. Evaluate the client's level of pain. c. Monitor the client's alkaline phosphatase levels. d. Observe the client for signs of hypersensitivity.

d. Observe the client for signs of hypersensitivity. 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.

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? a. Offer the morning dose of the medicine before breakfast. b. Have the client chew the pill if it is difficult to swallow. c. Encourage high energy fluid intake by providing sports drinks or sodas. d. Report symptoms of hypothyroidism such as fatigue and constipation.

d. Report symptoms of hypothyroidism such as fatigue and constipation. 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? a. Tolerance does not occur. b. Less agitation is experienced. c. The analgesic ceiling is higher. d. Respiratory depression is less.

d. Respiratory depression is less. 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.

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? a. Drink fluids between meals to relieve gastric distress. b. Monitor for an increase in blood pressure during therapy. c. Dissolve capsule contents in fruit juice for easier ingestion. d. Take at same time each day one hour before eating a meal.

d. Take at same time each day one hour before eating a meal. 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.

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? a. Avoid prolonged exposure to direct sunlight. b. Stay away from products containing alcohol. c. Ingest 8 oz of grapefruit juice with the medication. d. Take the medication when consuming food.

d. Take the medication when consuming food. 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.

The nurse administers the initial dose of a fentanyl (Duragesic) transdermal patch to a client. Which assessment finding should the nurse use to evaluate the effectiveness of the medication? a. The absence of seizures. b. The increase in lactation. c. The presence of bowel sounds. d. The number on the numeric pain scale.

d. The number on the numeric pain scale. Transdermal fentanyl is an opioid analgesic and has an onset and peak action of 6 to 12 hours after the initial dose. To evaluate the effectiveness of the medication the nurse should determine the client's level of pain before application and then throughout the next 12 hours for pain relief.

A client is prescribed cefadroxil (Duricef) for a urinary tract infection. The client informs the nurse that she is currently taking oral contraceptives (OCP). Which client information should the nurse provide? a. The antibiotic may be less effective while taking OCP. b. The medication combination potentiates the risk of adverse reactions. c. Avoid prolonged sun exposure while taking the antibiotic. d. Use an additional form of contraception until your menstrual cycle.

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

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? a. Snacks on dairy products such as yogurt or ice cream. b. Previously had a mild allergic reaction to a cephalosporin. c. Consumes alcoholic drinks occasionally on the weekends. d. Works twenty hours a week as a lifeguard at the local pool.

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