Question

A client diagnosed with depression is prescribed a monoamine oxidase inhibitor (MAOI). The nurse is providing dietary teaching to prevent hypertensive crises caused by tyramine-rich foods, which can dangerously elevate blood pressure when combined with MAOIs. Select all that apply meals that would not be safe or appropriate for the client on a tyramine-restricted diet:

Answer 1

Correct Answers:

Noodles with cheddar cheese sauce, smoked sausage, lettuce salad, yeast rolls
Avocado salad, ham, creamed potatoes, asparagus, chocolate cake
Macaroni and cheese, hot dogs, banana bread, caffeinated coffee

Rationale :

Noodles with cheddar cheese sauce, smoked sausage, lettuce salad, yeast rolls

💠 Cheddar cheese is an aged cheese, which contains high levels of tyramine.

💠 Smoked sausage is a cured/processed meat, a well-known tyramine source.

💠 Yeast rolls may contain active or concentrated yeast, which can contribute to tyramine exposure.

💠 The combination of aged cheese and processed meat significantly elevates blood pressure risk.

💠 This meal represents a classic high-risk MAOI dietary violation.

Avocado salad, ham, creamed potatoes, asparagus, chocolate cake

💠 Avocados, especially if overripe, contain moderate to high tyramine levels.

💠 Ham is a cured meat, making it unsafe for clients on MAOIs.

💠 Tyramine reactions are dose-dependent, and multiple risky items increase danger.

💠 MAOI–tyramine interactions can cause rapid and severe hypertension.

💠 This meal contains hidden tyramine sources that are commonly overlooked.

Macaroni and cheese, hot dogs, banana bread, caffeinated coffee

💠 Macaroni and cheese often contains aged or processed cheeses, which are high in tyramine.

💠 Hot dogs are processed meats, increasing tyramine exposure.

💠 Banana bread may be prepared with overripe bananas, another tyramine source.

💠 Caffeinated coffee can further increase blood pressure in clients taking MAOIs.

💠 Multiple interacting foods in this meal create a high risk for hypertensive crisis.

Mashed potatoes, ground beef patty, corn, green beans, apple pie

💠 This meal consists of fresh, unprocessed foods, which are naturally low in tyramine.

💠 It avoids aged, fermented, cured, and overripe foods, making it appropriate for a tyramine-restricted diet.

Answer 2

Correct Answers:

“I am so excited for my Italian vacation next month for 3 weeks!”

Rationale :

💠 Phenelzine (Nardil) is a monoamine oxidase inhibitor, which requires strict avoidance of tyramine-rich foods to prevent serious adverse reactions.

💠 Italian cuisine commonly includes aged cheeses, cured meats, fermented foods, and wine, all of which are high in tyramine.

💠 During extended travel, especially abroad, dietary control is difficult, increasing the chance of accidental tyramine ingestion.

💠 Tyramine accumulation while on an MAOI can trigger a sudden hypertensive crisis, potentially leading to severe headache, stroke, or death.

💠 This statement represents a direct medication–diet safety risk, making it the most concerning update.

Moving into a senior living facility

💠 This is a social/environmental change, not a medication safety issue.

💠 It does not increase the risk of MAOI-related adverse effects.

Son moving away

💠 This reflects a psychosocial stressor, not a pharmacologic danger.

💠 Emotional stress alone does not cause MAOI toxicity.

Rescuing a kitten

💠 Pet adoption can provide emotional support and mood benefits.

💠 There is no interaction with MAOI therapy.

Answer 3

Correct Answers:

The client has congestive heart failure (CHF) and is taking furosemide (Lasix).

Rationale :

💠 Lithium is excreted almost entirely by the kidneys, making serum levels highly sensitive to changes in renal perfusion and fluid balance.

💠 Furosemide causes sodium and water loss, and because lithium follows sodium, the kidneys compensate by reabsorbing more lithium, raising serum levels.

💠 Congestive heart failure reduces renal blood flow, further impairing lithium clearance and increasing accumulation risk.

💠 Fluid shifts and dehydration are common in CHF management, causing unpredictable lithium level fluctuations.

💠 This combination makes close and frequent lithium monitoring critical to prevent toxicity.

Arthritis treated with acetaminophen (Tylenol)

💠 Acetaminophen does not affect renal sodium handling.

💠 It is generally safe for pain management in clients taking lithium.

Epilepsy treated with diazepam

💠 Diazepam does not interfere with lithium excretion.

💠 There is no significant pharmacokinetic interaction affecting lithium levels.

Psoriasis treated with topical triamcinolone

💠 Topical corticosteroids have minimal systemic absorption.

💠 They do not significantly impact fluid balance or renal function.

Answer 4

Correct Answers:

“SSRIs increase serotonin concentration by making more serotonin available in the synaptic cleft.”

Rationale :

💠 SSRIs block the serotonin reuptake transporter (SERT) on the presynaptic neuron, preventing serotonin from being taken back up.

💠 This action increases the amount of serotonin available in the synaptic cleft, prolonging its effect on postsynaptic receptors.

💠 Enhanced serotonin signaling helps regulate mood, sleep, appetite, and emotional balance, improving depressive symptoms.

💠 SSRIs act on availability, not synthesis, of serotonin.

💠 Clinical improvement occurs after adaptive changes in neural signaling, explaining the delayed therapeutic onset.

SSRIs increase the production of serotonin within the presynaptic neuron

💠 SSRIs do not increase serotonin synthesis.

💠 Their action occurs after serotonin has already been released.

SSRIs cause an increase in the number of serotonin receptors at the postsynaptic terminal

💠 SSRIs do not directly increase receptor numbers.

💠 Any receptor changes occur secondarily over time, not as the primary mechanism.

SSRIs block muscarinic and alpha-1 norepinephrine receptors

💠 This mechanism describes tricyclic antidepressants, not SSRIs.

💠 SSRIs are selective for serotonin reuptake and avoid these receptor effects.

Answer 5

Correct Answers:

Psychoanalysis

Rationale :

💠 Free association is a core psychoanalytic technique that allows unconscious thoughts and feelings to emerge without censorship.

💠 Dream analysis is used to explore unconscious desires, fears, and internal conflicts influencing behavior.

💠 Transference is intentionally facilitated, helping clients project unconscious feelings onto the therapist for insight and resolution.

💠 Therapy is long-term and intensive, often lasting years with regular sessions, which matches the 3-year weekly treatment described.

💠 The primary goal is lasting personality restructuring, not short-term symptom relief.

Behavioral therapy

💠 Behavioral therapy focuses on observable behaviors and conditioning, not unconscious processes.

💠 It does not use dream analysis or transference.

Cognitive therapy

💠 Cognitive therapy targets conscious thought patterns and distortions, not the unconscious mind.

💠 Techniques such as free association are not used.

Interpersonal Therapy (IPT)

💠 IPT is time-limited and present-focused, addressing current relationships and roles.

💠 It does not explore unconscious conflicts or early childhood experiences.

Answer 6

Correct Answers:

Carotid

Rationale :

💠 The carotid arteries supply blood directly to the brain, making them critical for cerebral perfusion.

💠 Palpating both carotid arteries simultaneously can decrease blood flow to the brain, leading to dizziness, syncope, or cerebral ischemia.

💠 Bilateral pressure may also stimulate the carotid sinus, triggering a vagal response with bradycardia and hypotension.

💠 For safety, carotid pulses should be assessed one side at a time, especially in older adults or those with cardiovascular disease.

💠 This precaution helps prevent reduced cerebral oxygenation and neurologic compromise during assessment.

Popliteal

💠 Popliteal pulses can be assessed bilaterally without affecting cerebral circulation.

💠 There is no associated risk of syncope or vagal stimulation.

Brachial

💠 Brachial pulses are safe to assess on both arms simultaneously.

💠 Bilateral assessment does not interfere with vital organ perfusion.

Femoral

💠 Femoral pulses may be checked bilaterally when indicated.

💠 This does not compromise blood flow to the brain.

Answer 8

Correct Answers:

The ST segment is above the isoelectric line.

Rationale :

💠 ST-segment elevation reflects acute myocardial injury caused by complete or near-complete coronary artery occlusion.

💠 It represents ongoing transmural ischemia, where the full thickness of the heart muscle is affected.

💠 This ECG change is classically associated with ST-elevation myocardial infarction (STEMI).

💠 ST elevation correlates with the client’s symptoms of chest pain, dyspnea, and diaphoresis, which are hallmark signs of AMI.

💠 Recognition of this finding is critical because it requires immediate reperfusion therapy to prevent permanent myocardial damage.

QRS intervals are 0.08 second

💠 A QRS duration of 0.08 seconds is normal, indicating normal ventricular depolarization.

💠 It does not indicate myocardial ischemia or infarction.

PR intervals are 0.15 second

💠 A PR interval of 0.12–0.20 seconds is normal, reflecting normal atrioventricular conduction.

💠 PR interval changes are not diagnostic of acute MI.

QT interval is equal to the R-to-R interval

💠 QT interval varies with heart rate and must be corrected (QTc) for interpretation.

💠 This finding is not specific to myocardial infarction.

Answer 9

Correct Answers:

Irregular pulsations

Rationale :

💠 PVCs originate in the ventricles, causing early beats that interrupt the normal cardiac rhythm.

💠 These premature beats result in irregular pulsations when the nurse palpates the pulse.

💠 A compensatory pause often follows a PVC, making the pulse feel uneven or skipped.

💠 The irregularity is especially noticeable with frequent or consecutive PVCs.

💠 This finding directly corresponds with the electrical disturbance seen on cardiac monitoring.

S3 heart sounds

💠 An S3 is associated with heart failure and volume overload, not PVCs.

💠 PVCs affect rhythm, not ventricular filling sounds.

Increase in point of maximum impulse (PMI)

💠 A displaced or increased PMI suggests cardiac enlargement or hypertrophy.

💠 PVCs do not cause structural heart changes detectable on physical exam.

Bradycardia

💠 Bradycardia refers to a slow heart rate, not premature beats.

💠 PVCs may occur at normal or elevated heart rates.

Answer 10

Correct Answers:

Begin chest compressions immediately and call for help.

Rationale :

💠 Asystole is a non-shockable, pulseless rhythm, meaning there is no effective cardiac electrical activity.

💠 Early chest compressions are essential to maintain cerebral and coronary perfusion when no pulse is present.

💠 Calling for help activates the emergency response team, ensuring rapid access to advanced life support.

💠 Defibrillation is not indicated in asystole, making CPR the most critical first intervention.

💠 Prompt CPR improves survival chances by sustaining vital organ perfusion until advanced measures are initiated.

Administer atropine to stimulate heart activity

💠 Atropine is not recommended for routine management of asystole in current ACLS guidelines.

💠 It does not restore electrical activity in a heart with no rhythm.

Prepare the defibrillator for shock delivery

💠 Asystole is a non-shockable rhythm, unlike ventricular fibrillation or pulseless VT.

💠 Defibrillation would delay lifesaving CPR.

Administer a precordial thump

💠 Precordial thump is not effective for asystole and is rarely used in modern practice.

💠 It can delay CPR, worsening outcomes.
