Question

A 58-year-old man is receiving vancomycin as part of the treatment for a severe bone infection. After the infusion, he begins to experience some itching and flushing of the neck, face, and upper body. He reports no chills or difficulty breathing. What should the nurse suspect?

Answer 1

Correct Answers:

The IV dose may have infused too quickly.

Rationale :

🟦 The client’s symptoms of flushing and itching of the neck, face, and upper body are classic for Red Man Syndrome.

🟦 This reaction occurs when vancomycin is infused too rapidly, causing histamine release.

🟦 The absence of hypotension, bronchospasm, or respiratory distress helps rule out anaphylaxis.

🟦 Red Man Syndrome is rate-related, not immune-mediated, and is preventable.

🟦 Slowing the infusion rate and administering antihistamines usually resolves symptoms.

🟦 Incorrect Options:

An allergic reaction has occurred

🟦 True allergies typically involve urticaria, wheezing, or hypotension.

🟦 These findings are absent in this client.

The medication will not be effective

🟦 Effectiveness is unrelated to infusion-related flushing.

🟦 Vancomycin remains appropriate for bone infections.

An anaphylactic reaction is about to occur

🟦 Anaphylaxis includes airway compromise and cardiovascular instability.

🟦 This client shows none of these signs.

Answer 2

Correct Answers:

Gentamicin (Garamycin)
Ethambutol (Myambutol)
Rifabutin (Mycobutin)
Pyrazinamide

Rationale :

🟦 Streptomycin sulfate

🟦 Streptomycin is an aminoglycoside antibiotic that is effective against Mycobacterium tuberculosis, particularly in severe or resistant cases.

🟦 It works by inhibiting protein synthesis, leading to impaired bacterial replication.

🟦 Streptomycin is often used as part of combination therapy to reduce the risk of resistance.

🟦 It is especially useful in meningeal or disseminated TB due to its strong bactericidal action.

🟦 Monitoring is essential because it carries risks of ototoxicity and nephrotoxicity.

🟦 Ethambutol (Myambutol)

🟦 Ethambutol inhibits mycobacterial cell wall synthesis, weakening the organism and enhancing the effects of other TB drugs.

🟦 It is included in early TB treatment to prevent the development of drug resistance.

🟦 Ethambutol is particularly effective against actively dividing TB bacilli.

🟦 A key nursing consideration is monitoring for optic neuritis, which can cause visual changes.

🟦 Patients should be instructed to report blurred vision or color discrimination changes immediately.

🟦 Rifabutin (Mycobutin)

🟦 Rifabutin is a rifamycin antibiotic that works by inhibiting RNA synthesis in Mycobacterium tuberculosis.

🟦 It is often used as an alternative to rifampin, especially in patients with HIV infection due to fewer drug interactions.

🟦 Rifabutin is highly effective in reducing bacterial load during active TB infection.

🟦 It contributes significantly to shortening treatment duration when used appropriately.

🟦 Patients should be educated that it may cause orange discoloration of body fluids, which is harmless.

🟦 Pyrazinamide

🟦 Pyrazinamide is especially active in acidic environments, such as within macrophages where TB organisms reside.

🟦 It plays a critical role in the initial intensive phase of TB treatment.

🟦 This medication helps reduce treatment duration by rapidly decreasing the bacterial population.

🟦 Pyrazinamide enhances the effectiveness of other TB drugs when used in combination therapy.

🟦 Liver function must be monitored due to the risk of hepatotoxicity and hyperuricemia.

Answer 3

Correct Answers:

Brown-colored urine is a harmless side effect of the medication.

Rationale :

🟦 Nitrofurantoin commonly causes urine discoloration, including brown or dark yellow urine.

🟦 This effect is benign and expected during therapy.

🟦 It does not indicate kidney damage or treatment failure.

🟦 Patients should be reassured to continue the medication as prescribed.

🟦 Education prevents unnecessary anxiety and nonadherence.

🟦 Incorrect Options:

Drinking more fluid will prevent discoloration

🟦 Hydration does not alter drug pigment excretion.

🟦 Color change may persist despite fluid intake.

Increased RBC destruction causes brown urine

🟦 Hemolysis presents with additional systemic symptoms.

🟦 This is not associated with nitrofurantoin use.

The provider will change the medication

🟦 Discoloration alone is not a reason to discontinue therapy.

🟦 The infection can still be resolving.

Answer 4

Correct Answers:

Use a back-up method of contraception if taking oral contraceptives.

Rationale :

🟦 Doxycycline reduces the effectiveness of oral contraceptives.

🟦 This increases the risk of unintended pregnancy.

🟦 A back-up method should be used during therapy and shortly after.

🟦 Patient education prevents contraceptive failure.

🟦 This is a critical safety teaching point for reproductive-age patients.

🟦 Incorrect Options:

The drug is not teratogenic

🟦 Doxycycline is teratogenic and contraindicated in pregnancy.

🟦 It can cause fetal tooth discoloration.

Increase dairy intake

🟦 Dairy products reduce drug absorption.

🟦 They should be avoided near dosing times.

Nausea and vomiting are uncommon

🟦 GI upset is a common adverse effect.

🟦 Patients should be advised to take with food if tolerated.

Answer 5

Correct Answers:

Sulfonamides are not derived from biologic substances

Rationale :

🟦 Sulfonamides are synthetic antimicrobial agents, unlike many antibiotics derived from fungi or bacteria.

🟦 This distinction separates them pharmacologically from beta-lactams and macrolides.

🟦 Their mechanism involves inhibition of folic acid synthesis, not cell wall destruction.

🟦 They are classified as bacteriostatic, not bactericidal.

🟦 Understanding drug origin aids in classification and allergy assessment.

🟦 Incorrect Options:

Sulfonamides are bactericidal

🟦 They inhibit growth rather than kill bacteria.

🟦 This makes them bacteriostatic.

They have antifungal and antiviral properties

🟦 Sulfonamides act only against bacteria.

🟦 They have no antiviral or antifungal activity.

They increase folic acid synthesis

🟦 They block folic acid production.

🟦 Bacteria require folate for DNA synthesis.

Answer 6

Correct Answers:

Hypokalemia

Rationale :

🟦 Amphotericin B is nephrotoxic, leading to renal tubular damage.

🟦 Renal impairment causes excessive potassium loss, resulting in hypokalemia.

🟦 Low potassium levels increase the risk of cardiac dysrhythmias and muscle weakness.

🟦 Electrolyte monitoring is critical throughout therapy to prevent life-threatening complications.

🟦 Early identification allows timely potassium replacement and renal protection.

🟦 Incorrect Options:

Hypernatremia

🟦 Sodium imbalance is not a primary effect of amphotericin B.

🟦 Potassium loss is the major concern.

Hypermagnesemia

🟦 Amphotericin B more commonly causes magnesium loss, not excess.

🟦 Magnesium may decrease alongside potassium.

Hypocalcemia

🟦 Calcium levels are not the primary electrolyte affected.

🟦 Potassium monitoring takes priority.

Answer 7

Correct Answers:

If I have received the BCG vaccine recently, my Mantoux test result might be falsely positive, so I will need additional tests like a chest x-ray or QuantiFERON-TB Gold test

Rationale :

🟦 The BCG vaccine can cause false-positive Mantoux results.

🟦 A positive skin test does not confirm active tuberculosis.

🟦 Additional testing such as chest x-ray or IGRA testing is required.

🟦 These tests help distinguish latent infection from active disease.

🟦 Correct follow-up prevents misdiagnosis and unnecessary treatment.

🟦 Incorrect Options:

Positive Mantoux means active TB

🟦 A positive result only indicates exposure.

🟦 It does not confirm active disease.

Negative test rules out TB in immunosuppressed patients

🟦 Immunosuppression can cause false-negative results.

🟦 TB cannot be excluded based on this alone.

Reliable immediately after exposure

🟦 The test requires 2–8 weeks after exposure to become positive.

🟦 Immediate testing may be inaccurate.

Answer 8

Correct Answers:

Taking pyridoxine (B6)

Rationale :

🟦 Isoniazid interferes with vitamin B6 metabolism.

🟦 This deficiency causes peripheral neuropathy, presenting as tingling.

🟦 Pyridoxine supplementation prevents and treats neuropathy.

🟦 This intervention allows continuation of effective TB therapy.

🟦 Early treatment prevents permanent nerve damage.

🟦 Incorrect Options:

Changing to ethambutol

🟦 INH remains effective and should not be discontinued unnecessarily.

🟦 Neuropathy is manageable with supplementation.

Adding acetaminophen

🟦 This does not address nerve irritation.

🟦 It treats pain, not the cause.

Increasing oral fluids

🟦 Hydration does not affect neuropathy.

🟦 Vitamin replacement is required.

Answer 9

Correct Answers:

Ribavirin

Rationale :

🟦 Ribavirin is an antiviral effective against RSV.

🟦 It inhibits viral RNA synthesis, reducing replication.

🟦 Ribavirin may be used in severe RSV infections, especially in high-risk neonates.

🟦 Other antivirals listed do not target RSV.

🟦 Supportive care remains primary, with ribavirin as adjunct therapy.

🟦 Incorrect Options:

Acyclovir
🟦 Targets herpes viruses, not RSV.
🟦 Ineffective for respiratory syncytial virus.
Sofosbuvir
🟦 Used for hepatitis C treatment.
🟦 No role in RSV therapy.
Ganciclovir
🟦 Used for CMV infections.
🟦 Not effective against RSV.

Answer 10

Correct Answers:

Promoting hydration

Rationale :

🟦 Many antiviral medications are nephrotoxic.

🟦 Adequate hydration supports renal clearance of the drug.

🟦 This reduces the risk of acute kidney injury.

🟦 Hydration also helps prevent crystalluria and renal irritation.

🟦 Maintaining fluid balance is the top nursing priority.

🟦 Incorrect Options:

Enhancing bowel function

🟦 Constipation is not the primary risk.

🟦 Kidney protection is more urgent.

Promoting good circulation

🟦 Circulation is important but secondary.

🟦 Renal safety comes first.

Increasing tidal volume

🟦 Respiratory function is not directly affected.

🟦 Hydration has greater clinical impact.
