Question

A client receives a prescription for IV famotidine. Which finding indicates to the nurse the medication is effective?

Answer 1

Correct Answers:

Reduced epigastric pain.

Rationale :

⏺️Famotidine is an H2 receptor antagonist that decreases gastric acid secretion, promoting healing of gastric and duodenal ulcers and reducing symptoms of gastroesophageal reflux disease (GERD).

⏺️The most direct measure of effectiveness is symptom relief, especially a reduction in epigastric pain caused by acid irritation.

⏺️Other effects, such as improved sleep, may occur, but pain reduction reflects the primary therapeutic goal.

⏺️Pain relief indicates healing of the mucosa and improved gastric comfort.

⏺️Long-term therapy may be required to maintain remission.

Answer 3

Correct Answers:

Blood urea nitrogen 17 mg/dL (6.07 mmol/L).
Dosage in safe range.
No known allergies.
Peripheral IV (PIV) in large vein.

Rationale :

Blood urea nitrogen 17 mg/dL (within normal limits)

💎 Vancomycin is renally cleared; safe administration depends on adequate renal function to avoid drug accumulation and nephrotoxicity.

💎 A BUN of 17 mg/dL falls within the normal range (≈8–20 mg/dL), supporting appropriate clearance.

💎 The client’s creatinine 0.82 mg/dL further corroborates preserved kidney function, lowering immediate risk for toxicity.

💎 With normal renal indices, no pre‑dose renal adjustment is required (continue to monitor levels per protocol if therapy continues).

💎 Stable renal labs help prevent AKI and supratherapeutic exposure during prophylaxis.

Dosage in safe range

💎 Vancomycin 1 g IV is a commonly used adult prophylactic dose and aligns with many perioperative protocols when weight‑based calculations are not mandated.

💎 The ordered infusion 250 mL at 125 mL/hr ≈ 120 min, which is slower than the minimum 60‑minute requirement for 1 g, helping prevent infusion reactions (e.g., red man syndrome).

💎 The effective, guideline‑concordant dose and rate support antibacterial coverage while minimizing adverse effects.

💎 Dose safety always pairs with clinical monitoring (vitals, infusion site, signs of reaction).

💎 Appropriate dosing and rate together optimize efficacy and tolerability.

No known allergies

💎 Absence of documented drug allergy significantly reduces immediate risk for IgE‑mediated anaphylaxis or severe hypersensitivity to vancomycin.

💎 Screening for prior reactions to glycopeptides (e.g., vancomycin) is a critical safety step before first-dose administration.

💎 Even without allergies, the nurse should monitor closely for infusion‑related reactions (flushing, pruritus, hypotension).

💎 Clear allergy status enables timely prophylaxis without delay for alternative agents.

💎 Maintaining an updated allergy record is essential for safe antimicrobial stewardship.

Peripheral IV (PIV) in large vein

💎 Vancomycin is an irritant and can cause phlebitis if infused through small or fragile veins.

💎 A 20‑gauge PIV in the antecubital fossa qualifies as a large, high‑flow peripheral vein, lowering local infusion complications.

💎 Proper vein selection helps preserve line patency and ensures the ordered infusion rate can be safely maintained.

💎 Good vascular access reduces infiltration/extravasation risk and improves patient comfort.

💎 Optimal line choice is a core safety measure for vesicant/irritant antimicrobials.

Answer 4

Correct Answers

Blank 1 Correct Option: adverse drug reaction.
Blank 2 Correct Option: antibiotic.

Rationale :

🟠The client’s dizziness, headache, flushing, burning sensation on extremities, and erythema shortly after starting vancomycin are classic signs of "red man syndrome", which is a rate-related adverse drug reaction rather than an allergy.

🟠This reaction occurs when histamine is released due to rapid infusion of the antibiotic.

🟠It is not related to cardiac bradycardia, hypovolemia, or fluid overload.

🟠The drop in blood pressure is due to vasodilation from histamine release, not from fluid loss or heart rate changes.

🟠Prevention includes infusing vancomycin slowly (≥60 minutes for 1 g) and premedicating with antihistamines if the patient has a history of infusion reactions.

🟠Stopping the infusion and notifying the provider—as done here—are the appropriate immediate interventions.

Answer 5

Correct Answers

Blank 1 Correct Option: anaphylaxis.
Blank 2 Correct Option: dysrhythmias.
Blank 3 Correct Option: cardiac arrest.

Rationale :

Anaphylaxis

The rapid onset of flushing, diffuse erythema, hives (urticaria), nausea, hypotension, and tachycardia minutes after the infusion is classic for anaphylaxis, a life‑threatening systemic hypersensitivity reaction.
In anaphylaxis, mast‑cell mediator release (e.g., histamine) triggers peripheral vasodilation and capillary leak, producing the observed hypotension and warm, flushed skin.
The development of hives distinguishes this from simple rate‑related flushing and indicates a generalized immunologic reaction requiring emergency treatment.
Untreated, anaphylaxis can progress to airway edema/bronchospasm, shock, and multisystem compromise.
Immediate priorities are stop the offending agent, activate emergency response, ensure airway/breathing/circulation, and administer epinephrine with high‑flow oxygen and IV fluids as indicated.

Dysrhythmias

During anaphylaxis, profound vasodilation and relative hypovolemia can precipitate myocardial hypoperfusion, predisposing to cardiac dysrhythmias.
Concurrent tachycardia (compensatory) and hypotension increase myocardial oxygen demand while decreasing supply, further raising arrhythmia risk.
Emergency therapies (e.g., epinephrine, beta‑agonists) are lifesaving but can also provoke dysrhythmias, especially in older adults or those with cardiac history.
Continuous cardiac monitoring, prompt correction of hypoxia and hypotension, and judicious use of vasoactive agents are essential to minimize this risk.
Early recognition and stabilization of hemodynamics reduce progression to malignant rhythms.

Cardiac arrest

Severe anaphylaxis can deteriorate to distributive shock with refractory hypotension, culminating in cardiac arrest if not rapidly reversed.
Airway edema and bronchospasm may cause hypoxemia, another direct pathway to pulseless arrest.
Escalating dysrhythmias in the setting of hypoxia and shock can degenerate into ventricular fibrillation or asystole.
Given the patient’s age and cardiac history, the threshold for rapid escalation (airway equipment at bedside, ACLS readiness, large‑bore IV access, aggressive crystalloid boluses) should be low.
Early epinephrine, oxygenation/ventilation, and volume resuscitation are the proven measures that prevent progression to arrest.

Answer 6

Correct Answers

Blank 1 Correct Option: skin color.
Blank 2 Correct Option: increased heart rate.
Blank 3 Correct Option: dyspnea.

Rationale :

Skin color

🔹 The client’s skin remains red despite improvement in other vital signs, which is a residual manifestation of the ongoing adverse reaction to vancomycin.

🔹 Skin flushing and erythema are hallmark findings in infusion-related reactions like red man syndrome, even after initial treatment.

🔹 This persistent skin change indicates that the histamine-mediated vascular response is still active, though less severe.

Increased heart rate

🔹 Although the heart rate improved from 110 bpm to 90 bpm and then to 60 bpm, any episode of tachycardia during the reaction is a sign of systemic involvement.

🔹 The earlier elevated heart rate reflects the body’s compensatory response to vasodilation and hypotension.

🔹 Monitoring heart rate trends is crucial because a recurrence or rebound in tachycardia could signal worsening of the reaction.

Dyspnea

🔹 Even though it is not directly stated that the client is currently breathless, dyspnea is a possible ongoing symptom in systemic hypersensitivity due to histamine-induced bronchoconstriction or airway involvement.

🔹 Continued respiratory monitoring is essential because airway compromise can develop later in the reaction, especially if it progresses toward anaphylaxis.

🔹 Early identification allows for prompt intervention with oxygen therapy, bronchodilators, or escalation to advanced airway management.

Answer 7

Correct Highlights :

Shaking is lessened.
no longer flushed.
No longer itching.
Anxiety has decreased.
Skin warm and dry.
Heart rate 62 beats/minute,
No chest pain noted.
Respirations are even and unlabored.

Rationale :

Shaking is lessened

✅Rigors and restlessness in severe infusion reactions are driven by catecholamine surge, histamine release, and distress.

✅A reduction in shaking shows neuro‑autonomic stabilization and improved perfusion/oxygenation.

✅It also reflects the therapeutic effect of diphenhydramine and corticosteroids in dampening mediator activity.

✅With less motor agitation, myocardial oxygen demand falls, lowering the risk of dysrhythmias.

✅Clinically, this is a trajectory toward recovery, not simply masking symptoms.

No longer flushed

✅ Flushing in this context is a marker of histamine‑mediated vasodilation (e.g., red‑man–type reaction).

✅Resolution of flushing indicates decreased histamine effect and restoration of vascular tone.

✅As cutaneous vasodilation abates, systemic blood pressure stabilizes, and heat loss diminishes.

✅This aligns with the improving vitals noted after treatment. The skin finding is a visible surrogate for systemic improvement.

No longer itching

✅Pruritus is a classic H1‑receptor–mediated symptom.

✅ Its resolution signals effective antihistamine therapy and declining mast‑cell mediator activity.

✅Less itching also means lower stress response, which supports hemodynamic stability.

✅Together with fading hives/flushing, it marks symptom control rather than progression. This is a direct, patient‑reported indicator of recovery.

Anxiety has decreased

✅Acute anxiety often reflects air hunger, chest discomfort, and autonomic activation during reactions.

✅Improvement suggests better oxygenation, stable circulation, and symptom relief.

✅Lower anxiety reduces sympathetic drive, helping normalize heart rate and blood pressure.

✅ It also improves cooperation with care and rest.

✅Thus, decreased anxiety is a holistic sign of physiologic stabilization.

Skin warm and dry

✅Early reactions can produce flushed, clammy, or diaphoretic skin.

✅Warm, dry skin indicates normalized perfusion and thermoregulation without excessive vasodilation or catecholamine‑driven diaphoresis.

✅ It corroborates the return to hemodynamic steadiness seen in the vitals.

✅This finding is consistent with resolution of shock physiology.

✅ It is a routine but reliable bedside marker of recovery.

Heart rate 62 bpm; BP 130/72 mm Hg (stable)

✅The patient moved from tachycardia with hypotension to euvolemic, normotensive parameters after therapy and fluids.

✅Stable vitals reflect reversed vasodilation, adequate preload/afterload, and reduced sympathetic stress.

✅A resting heart rate in the low 60s is appropriate given pacemaker context and clinical calm.

✅This reduces risk of myocardial ischemia and dysrhythmias. Vitals are the primary objective evidence of recovery.

No chest pain noted

✅Earlier “pounding chest pain” signaled autonomic surge and potential myocardial strain.

✅Absence of chest pain with normalized vitals and imaging (CXR/echo reassuring) supports cardiac stability post‑reaction and post‑procedure.

✅It lowers concern for ischemia, lead malposition, or pneumothorax.

✅This symptom resolution aligns with the overall down‑trend in severity.

✅It’s an important safety milestone before transfer.

Respirations even and unlabored

✅Dyspnea can accompany reactions via bronchospasm or airway edema.

✅Quiet, effortless breathing indicates no ongoing bronchospasm, adequate gas exchange, and resolved airway threat.

✅ Improved respiratory pattern also curbs work of breathing, reducing cardiac workload.

✅This satisfies the “A/B/C” priorities (airway/breathing) for recovery readiness.

✅It supports safe step‑down from close monitoring.

Answer 8

Correct Answers:

Leave the patch in place and administer a PRN dose of sublingual nitroglycerin.

Rationale :

💎Transdermal nitroglycerin patches provide continuous prophylactic antianginal therapy but are not for acute relief of chest pain.

💎When a client experiences angina while on a patch, short-acting sublingual nitroglycerin should be given for rapid vasodilation and symptom relief.

💎Leaving the patch in place maintains baseline nitrate blood levels to prevent further ischemic episodes.

💎PRN nitroglycerin dosing can be repeated every 5 minutes up to 3 doses if pain persists, with close BP monitoring for hypotension.

💎This approach aligns with standard chest pain protocols to rapidly restore myocardial oxygen balance.

Answer 9

Correct Answers:

Watch for signs of jitteriness or diaphoresis.

Rationale :

⏺️GLP-1 receptor agonists (e.g., exenatide, liraglutide) improve glycemic control by increasing insulin secretion, decreasing glucagon release, and slowing gastric emptying.

⏺️When combined with a sulfonylurea like glimepiride, there is an increased risk of hypoglycemia because both drugs enhance insulin effects.

⏺️Hypoglycemia symptoms include jitteriness, diaphoresis, shakiness, dizziness, and confusion.

⏺️Clients should be instructed to carry rapid-acting carbohydrate sources and monitor blood glucose closely, especially during therapy initiation or dose changes.

⏺️Early recognition and treatment of hypoglycemia prevent severe complications such as seizures or loss of consciousness.
