Immune Medications

A nurse administers diphenhydramine to a 9 year old client for hives. The client becomes hyperactive, jittery and tachycardic. What type of drug reaction is this client experiencing? A. Tolerance B. Toxic C. Allergic D. Idiosyncratic

D. An idiosyncratic drug reaction is one that is unusual or abnormal for the medication in question. Diphenhydramine (Benadryl) often produces drowsiness. However, it is possible for children to experience the opposite - hyperactivity, jitteriness, excitement, and tachycardia. This is considered an idiosyncratic reaction. Tolerance occurs when a client requires a higher dose of a drug to produce the same effect. This may have been evidenced by seeing no change in the client's original symptoms despite medicating them. Toxicity is typically evidenced by extreme versions of the medications usual effects. In this case, being overly drowsy or increased CNS depression would have indicated toxicity. Allergic reactions are characterized by swelling, itching, hives, and possible angioedema

A nurse is caring for a client that is taking carbapenems and having some adverse gastrointestinal effects. The nurse is reviewing the client's side effects and knows that all except which of the following are gastrointestinal effects of carbapenems? A. Diarrhea B. Nausea C. Vomiting D. Bloody stools

D. Bloody stools are not an adverse effect that would be caused by carbapenems use.

The client is taking rifampin and has developed a hypersensitivity reaction to the drug C. The client is taking multiple nephrotoxic drugs and has gone into renal failure D. The client is taking isoniazid and has neurotoxicity from the drug

D. One of the most common treatments for TB is isoniazid, which carries a risk for CNS toxicity. This can present in the form of a seizure or coma, and can manifest just 30 minutes after a dose of the drug.

A client presents to the emergency room with an abscess that was previously treated but is not responding to penicillin. The nurse knows the next line of antibiotics will be which of the following? A. Granulocyte colony-stimulating factor B. Ganciclovir C. Gatifloxacin D. Gentamicin

D. This medication is an anti-infective that is the next step in treatment for gram negative bacteria when penicillins are ineffective.

A client has a vancomycin trough of 22 mcg/mL. Which of the following is of primary concern to the nurse? A. Clostridium Difficile B. Red man syndrome C. Dizziness D. Nephrotoxicity

D. This trough is above the therapeutic range of 10-20 mcg/mL. This client is at risk for nephrotoxicity, or acute kidney injury, which could result in short-term dialysis, or in extreme cases, kidney transplantation. This would be the primary concern for the nurse.

A nurse is caring for a client requiring an antibiotic and the healthcare provider wants to prescribe a carbapenem drug. The nurse knows that which of the following drugs is not a carbapenem antibiotic? A. Meropenem (Merrem) B. Doripenem (Doribax) C. Imipenem-cilastatin (Primaxin) D. Vancomycin (Vancocin)

D. Vancomycin is a glycopeptide.

The nurse is caring for a client that is receiving aminoglycoside. The nurse knows to assess the client for which of the following adverse effects? Select all that apply. A. Ototoxicity B. Nephrotoxicity C. Vomiting D. Heart burn E. Fever

A, B - Ototoxicity is an adverse effect of aminoglycoside use. Ototoxicity would present as hearing problems, ringing in the ears, and balance problems. Nephrotoxicity is an adverse effect of aminoglycoside use. The client should be watched for nephrotoxicity which would present as decreased urinary output, fluid retention, nausea, weakness, and confusion. Vomiting, heart burn, and fever could occur, but are not adverse effects related to aminoglycoside use.

The nurse has been asked to give clindamycin to a client. For what type of infection is clindamycin effective? Select all that apply. A. Bone infection B. Bacterial septicemia C. Sinusitis D. Gynecological infection E. Brain abscess

A, B, D - Clindamycin can be used in bone and joint infections, head and neck infections, preoperative prophylaxis, gynecological infections, intra-abdominal infections, pneumonia, and infections of the skin and soft tissue. Brain abscess infections are usually treated with a ceftin antibiotic, metronidazole, or vancomycin. Sinusitis is often viral, so antibiotics are not prescribed.

The client has an order for penicillin for strep throat. Before giving the medication, the nurse notes some drug-drug interactions and should contact the provider if the client is taking which of the following medications? Select all that apply. A. Potassium supplements B. Aldactone C. Acetaminophen D. Captopril E. Ibuprofen

A, B, D - Penicillin increases potassium in the body. ACE inhibitors, potassium sparing diuretics, and potassium supplements given concurrently with penicillin can cause these levels to become dangerously high. Acetaminophen and ibuprofen does not affect potassium levels, and is safe to take concurrently with penicillins.

A nurse is caring for a client receiving carbapenems and knows that drug-induced seizure activity is increased in which of the following client populations? A. Renal impaired B. Pediatric C. Hepatic impaired D. Drug users E. Older adults

A, B, E - Renal impaired patients are at an increased risk for drug-induced seizures because the kidneys can not excrete as well so medication builds up in the body. Carbapenems can cause CNS toxicity and seizures and the pediatric population is more at risk. The older adult population is at an increased risk for drug-induced seizures because they do not metabolize medications as well. Carbapenem is metabolized in the renal system so the liver is not involved. If the drug was metabolized by the liver then a hepatic impaired client would be at risk. Drug use does not increase the risk of seizures from carbapenem medications.

The nurse reviews a client's vancomycin trough result prior to giving the next dose. The level is 8 mcg/mL. For which of the following reasons is the nurse concerned? Select all that apply. A. The client is receiving inadequate drug therapy B. The client is at risk of nephrotoxicity C. The client is at an increased risk for bacterial resistance D. The client is receiving a drug that was mixed in error by the pharmacy E. The client could develop an opportunistic infection

A, C - If the trough is too low, the client is not receiving adequate antibiotic coverage and the infection may worsen. A therapeutic vancomycin trough is 10-20 mcg/mL. If the value is below this range, the pathogen can develop resistance to the drug. The client is at risk of nephrotoxicity when the level is above 20 mcg/mL. The client is not responding to the drug at the dose that is being administered, but this does not mean that the pharmacy made an error. An opportunistic infection occurs when a client's immune system is compromised, not when a drug is at a sub-therapeutic level in the body.

The infusion nurse understands that immunoglobulins are effective against which of the following? Select all that apply. A. Myasthenia Gravis B. Disseminated intravascular coagulation C. Varicella-zoster D. Rheumatoid Arthritis E. Cystic fibrosis

A, C - Intravenous immune globulin (IVIG) therapy is often used for neuroimmunologic disorders such as myasthenia gravis. Immunoglobulins are used to treat varicella zoster. Treatment for DIC is specific to the situation. It may include plasma for a client who has used up clotting factors, or blood thinner medication for a client whose blood is clotting. Rheumatoid arthritis is treated with disease-modifying antirheumatic drugs (DMARDs), such as methotrexate and hydroxychloroquine. Cystic fibrosis treatment centers on symptom management, and includes respiratory treatments, enzymes, and nutritional supplements.

The community health nurse is conducting an educational session to teach about tuberculosis in an HIV positive population. Which of the following is accurate regarding extrapulmonary tuberculosis? Select all that apply. A. Extrapulmonary tuberculosis is more likely to affect persons who are immunocompromised B. Extrapulmonary tuberculosis refers to TB that has traveled to the brain C. Extrapulmonary tuberculosis is more likely to be seen in children than adults D. Extrapulmonary tuberculosis is often misdiagnosed E. Extrapulmonary tuberculosis is more manageable than pulmonary TB

A, C, D - Extrapulmonary tuberculosis occurs when a client has pulmonary tuberculosis and the body is not able to mount a significant immune response. The illness spreads to the kidneys, bone, and brain. At-risk populations for this condition includes persons who are immunocompromised and children. It is common to be misdiagnosed when this condition is present. For example, a person with extrapulmonary TB in the bones may complain of pain, and be diagnosed with a bone bruise or sprain. Extrapulmonary TB can be present in the brain, bones, and kidneys. A person with extrapulmonary TB still has the primary TB infection in the lungs.

A nurse receives in report that a client will be discharged with a prescription for oral fluoroquinolone and knows that the client would have which of the following types of infections? Select all that apply. A. Sexually transmitted infections B. Ear infections C. Urinary tract infections D. Respiratory infections E. HSV

A, C, D - Fluoroquinolone treats gram-positive infections that cause sexually transmitted infections, urinary tract infections, and respiratory infections. Fluoroquinolones are not indicated for ear infections. HSV is herpes simplex virus and although it is a sexually transmitted infection, it is a virus, which is not treated with antibiotics and instead with an antiviral called acyclovir.

The nurse is reviewing assigned clients. The nurse anticipates administering anti-viral medications to which of the following patients? Select all that apply. A. Smallpox B. Pneumonia C. Herpes D. HIV/AIDS E. Clostridium difficile

A, C, D - Smallpox and herpes are treated with antiviral medication. HIV/AIDS is treated with antiretroviral medication. Clostridium difficile is treated with antibiotics and antifungals. Pneumonia is treated with antibiotics, not antivirals.

A client has been prescribed metronidazole for an infection. The nurse should counsel this client not to take this drug if he has which of the following conditions? Select all that apply. A. Alcohol intoxication B. Diabetes C. Prolonged Q-T interval D. Numbness or tingling in the hands and feet E. Liver disease

A, C, D, E - Metronidazole is an antibiotic medication taken to control infections but it can cause some significant side effects and the patient should not take the drug if certain conditions are present. These include heart arrhythmias, such as a prolonged Q-T interval, liver disease, neuropathy and acute alcohol intoxication. Metronidazole does not affect blood sugar.

A nursing student is studying antifungals and knows that antifungals have which of the following suffixes? Select all that apply. A. -FUNGIN B. -FRON C. -AZIN D. -AZOLE E. -APRIL

A, D - Antifungals have -AZOLE & -FUNGIN suffixes.

A nursing student is caring for a client receiving sulfonamides. The student is reviewing this drug class with the nurse and correctly states that the drug is contraindicated in which of the following client populations? Select all that apply. A. Pregnant women B. Older adult females C. Girls between 12-16 years old D. Infants E. Males

A, D - Sulfonamide use is contraindicated in this population. Sulfonamides can cause adverse effects to an unborn fetus and an infant. Sulfonamides compete with bilirubin for binding to serum albumin. This causes free bilirubin levels to rise in the presence of sulfonamides. This puts the fetus and infant at risk for hyperbilirubinemia, jaundice, and kernicterus.

A nurse is giving a client education on tetracycline use and asks about other medications that the client takes. The nurse would be concerned by which of the following other medications being used with tetracyclines? Select all that apply. A. Iron B. Tylenol C. Probiotics D. Antacids E. Oral anticoagulants

A, D, E - Iron preparations and antacids interact with tetracyclines, reducing effectiveness. Oral anticoagulants interact with tetracyclines. Tetracyclines will cause an increase in bleeding time, so caution needs to be taken for a client on anticoagulants. Probiotics do not interact and would be good for the client to take since tetracyclines can alter the intestinal flora. Tylenol does not interact with tetracyclines.

What's an adverse reaction to aminoglycosides? A. Peripheral nerve toxicity B. Cardiotoxicity C. Hepatotoxicity D. Toxic megacolon

A. Adverse reactions to aminoglycosides include neuromuscular reactions, ranging from peripheral nerve toxicity to neuromuscular blockade, ototoxicity, and renal toxicity.

The nurse notes that a client will be receiving a lincosamide antibiotic for an anaerobic infection. Which of the following types of infection is considered to be anaerobic? A. Peritonitis B. Pharyngitis C. Otitis media D. Cellulitis

A. Anaerobic bacteria do not require oxygen for growth, so they are not common on the outside of the body or near a rich blood supply.

The preceptee correctly explains to the nurse that the mechanism of action of anti-tubercular medications is which of the following? A. Inhibiting protein synthesis in the mycobacterium B. Building up mycobacterium cell walls C. Creating gaps in the mycobacterium synapses D. Preventing neurotransmitter release between the bacterial cells

A. Anti-tubercular medication inhibits protein synthesis, which prevents RNA/DNA replication. This prevents the bacteria from communicating with each other.

The nurse is caring for a client receiving an antifungal and knows that which of the following interactions occur with this drug class? A. Decrease in anticoagulant effectiveness B. Increase in contraceptive effectiveness C. Increase in anticoagulant effectiveness D. Increase in hypoglycemic effectiveness

A. Anticoagulant effectiveness is decreased with antifungal drug use.

The nurse knows that which of the following is true of the mechanism of action of antiviral medications? A. They inhibit replication B. They interfere with fungal DNA synthesis C. They inhibit protein synthesis D. They prevent synthesis of folic acid

A. Antiviral medications inhibit replication of the virus, which either kills or suppresses the virus by blocking the activity of polymerase enzymes.

A. Warfarin is potentiated by macrolide use and erythromycin is a macrolide. Macrolides may increase INR by inhibiting warfarin's metabolism.

A client who is human immunodeficiency virus seropositive has been taking stavudine. The nurse should monitor which most closely while the client is taking this medication? 1. Gait 2. Appetite 3. Level of consciousness 4. Gastrointestinal function

Answer: 1 Rationale: Stavudine is an antiretroviral used to manage human immunodeficiency virus infection in clients who do not respond to or who cannot tolerate conventional therapy. The medication can cause peripheral neuropathy, and the nurse should monitor the client's gait closely and ask the client about paresthesia. Options 2, 3, and 4 are unrelated to this medication.

The nurse caring for a client who is taking an aminoglycoside should monitor the client for which adverse effects of the medication? Select all that apply. 1. Seizures 2. Ototoxicity 3. Renal toxicity 4. Dysrhythmias 5. Hepatotoxicity

Answer: 2, 3, 4 Rationale: Aminoglycosides are administered to inhibit the growth of bacteria. Adverse effects of this medication include confusion, ototoxicity, renal toxicity, gastrointestinal irritation, palpitations or dysrhythmias, blood pressure changes, and hypersensitivity reactions. Therefore, the remaining options are incorrect.

Ketoconazole is prescribed for a client with a diagnosis of candidiasis. Which interventions should the nurse include when administering this medication? Select all that apply. 1. Restrict fluid intake. 2. Monitor liver function studies. 3. Instruct the client to avoid alcohol. 4. Administer the medication with an antacid. 5. Instruct the client to avoid exposure to the sun. 6. Administer the medication on an empty stomach.

Answer: 2, 3, 5 Rationale: Ketoconazole is an antifungal medication. There is no reason for the client to restrict fluid intake; in fact, this could be harmful to the client. The medication is hepatotoxic, and the nurse monitors liver function. It is administered with food (not on an empty stomach), and antacids are avoided for 2 hours after taking the medication to ensure absorption. The client is also instructed to avoid alcohol. In addition, the client is instructed to avoid exposure to the sun, because the medication increases photosensitivity.

Amikacin is prescribed for a client with a bacterial infection. The nurse instructs the client to contact the primary health care provider (PHCP) immediately if which occurs? 1. Nausea 2. Lethargy 3. Hearing loss 4. Muscle aches

Answer: 3 Rationale: Amikacin is an aminoglycoside. Adverse effects of aminoglycosides include ototoxicity (hearing problems), confusion, disorientation, gastrointestinal irritation, palpitations, blood pressure changes, nephrotoxicity, and hypersensitivity. The nurse instructs the client to report hearing loss to the PHCP immediately. Lethargy and muscle aches are not associated with the use of this medication. It is not necessary to contact the PHCP immediately if nausea occurs. If nausea persists or results in vomiting, the PHCP should be notified.

The nurse is reviewing the results of serum laboratory studies drawn on a client with acquired immunodeficiency syndrome who is receiving didanosine. The nurse interprets that the client may have the medication discontinued by the health care provider if which elevated result is noted? 1. Serum protein level 2. Blood glucose level 3. Serum amylase level 4. Serum creatinine level

Answer: 3 Rationale: Didanosine can cause pancreatitis. A serum amylase level that is increased to 1.5 to 2 times normal may signify pancreatitis in the client with acquired immunodeficiency syndrome and is potentially fatal. The medication may have to be discontinued. The medication is also hepatotoxic and can result in liver failure.

The nurse is caring for a postrenal transplantation client taking cyclosporine. The nurse notes an increase in one of the client's vital signs, and the client is complaining of a headache. What vital sign is most likely increased? 1. Pulse 2. Respirations 3. Blood pressure 4. Pulse oximetry

Answer: 3 Rationale: Hypertension can occur in a client taking cyclosporine, and because this client is also complaining of a headache, the blood pressure is the vital sign to be monitored most closely. Other adverse effects include infection, nephrotoxicity, and hirsutism. Options 1, 2, and 4 are unrelated to the use of this medication.

The nurse is caring for a client who has been taking a sulfonamide and should monitor for signs and symptoms of which adverse effects of the medication? Select all that apply. 1. Ototoxicity 2. Palpitations 3. Nephrotoxicity 4. Bone marrow suppression 5. Gastrointestinal (GI) effects 6. Increased white blood cell (WBC) count

Answer: 3, 4, 5 Rationale: Adverse effects of sulfonamides include nephrotoxicity, bone marrow suppression, GI effects, hepatotoxicity, dermatological effects, and some neurological symptoms including headache, dizziness, vertigo, ataxia, depression, and seizures. Options 1, 2, and 6 are unrelated to these medications.

The nurse is assigned to care for a client with cytomegalovirus retinitis and acquired immunodeficiency syndrome who is receiving foscarnet, an antiviral medication. The nurse should monitor the results of which laboratory study while the client is taking this medication? 1. CD4+ T cell count 2. Lymphocyte count 3. Serum albumin level 4. Serum creatinine level

Answer: 4 Rationale: Foscarnet is toxic to the kidneys. The serum creatinine level is monitored before therapy, two or three times per week during induction therapy, and at least weekly during maintenance therapy. Foscarnet also may cause decreased levels of calcium, magnesium, phosphorus, and potassium. Thus, these levels also are measured with the same frequency.

The client with acquired immunodeficiency syndrome and Pneumocystis jiroveci infection has been receiving pentamidine. The client develops a temperature of 101° F (38.3° C). The nurse continues to assess the client, knowing that this sign most likely indicates which condition? 1. That the dose of the medication is too low 2. That the client is experiencing toxic effects of the medication 3. That the client has developed inadequacy of thermoregulation 4. That the client has developed another infection caused by leukopenic effects of the medication

Answer: 4 Rationale: Frequent adverse effects of this medication include leukopenia, thrombocytopenia, and anemia. The client should be monitored routinely for signs and symptoms of infection. Options 1, 2, and 3 are inaccurate interpretations.
