Question

A nurse administers nitroglycerin to a client. Which finding indicates that the medication has been therapeutic?

Answer 1

Correct Answers:

Reports minimal chest pain

Rationale :

💊Nitroglycerin is a vasodilator that increases coronary blood flow to the heart muscle.

❤️‍🔥The main therapeutic goal of nitroglycerin is to relieve anginal chest pain caused by myocardial ischemia.

🫀When blood flow and oxygen delivery to the myocardium improve, the client will report minimal or no chest discomfort, which shows the drug is effective.

📉Changes like decreased blood pressure or the presence of a headache are expected side effects, but they are not the primary measure of therapeutic success.

📌Core Message

Nitroglycerin is considered effective when anginal chest pain decreases, not just when vital signs or side effects change.

Answer 2

Correct Answers:

Several days

Rationale :

🕒Warfarin works by inhibiting the synthesis of vitamin K–dependent clotting factors, which naturally have long half-lives.

📚Because these existing clotting factors must be cleared from circulation first, it takes several days before the full anticoagulant effect is seen.

🔁This delayed onset is why bridging therapy with a faster-acting anticoagulant, like heparin, is often used initially.

🧪Monitoring INR values over several days helps confirm when the medication has reached a therapeutic level.

📌Core Message

Warfarin has a delayed onset, taking several days to reach a therapeutic anticoagulant effect due to the time needed to clear existing clotting factors.

Answer 3

Correct Answers:

"I will take my theophylline capsule in the evening before bed."

Rationale :

🚑Theophylline is a xanthine bronchodilator that can cause central nervous system stimulation, including insomnia.

🧬Because of this stimulating effect, taking the medication at bedtime can interfere with sleep quality and rest.

💉The drug is usually best taken at consistent times, often earlier in the day, to maintain a steady therapeutic level while minimizing sleep disturbance.

🩸The statement about taking it before bed shows a knowledge deficit, so it indicates a need for additional education.

📌Core Message

Theophylline can stimulate the CNS, so it should not be taken at bedtime, and a plan to take it before sleep signals the need for further teaching.

Answer 4

Correct Answers:

Administer vitamin K.

Rationale :

🩺Warfarin exerts its effect by antagonizing vitamin K, which is necessary for clotting factor synthesis.

🌬️In an unintentional overdose, the priority is to reverse excessive anticoagulation to reduce the risk of serious bleeding.

🌡️Administering vitamin K directly counteracts warfarin’s action and helps restore normal clotting ability.

💭Supportive measures like monitoring vital signs are important, but reversal of the drug’s effect with vitamin K addresses the root cause most effectively.

📌Core Message

In warfarin overdose, vitamin K is the priority intervention because it reverses the anticoagulant effect and reduces the risk of serious bleeding.

Answer 5

Correct Answers:

Drowsiness
Dry mouth
Constipation

Rationale :

💨Diphenhydramine is a first-generation antihistamine that crosses the blood–brain barrier, leading to sedation and drowsiness.

🫁It also has strong anticholinergic properties, which reduce secretions and commonly cause dry mouth.

🔊These anticholinergic effects slow gastrointestinal motility, making constipation a frequent adverse effect, especially in older adults.

🧂Older adult clients are particularly vulnerable to sedation, confusion, and anticholinergic side effects, so monitoring for drowsiness, dry mouth, and constipation is essential.

📌Core Message

Diphenhydramine commonly causes sedation and anticholinergic effects such as dry mouth and constipation, which are especially important to monitor in older adults.

Answer 6

Correct Answers

This medication will help to lower cholesterol levels. [ Indicated ]
Report yellowing of the skin to your provider. [ Indicated ]
Gemfibrozil should be taken at the same time as atorvastatin. [ Not Indicated ]
Fatigue is a common side effect of this medication. [ Indicated ]

Rationale :

🪥Gemfibrozil is a fibric acid derivative that primarily lowers triglycerides and can improve the overall lipid profile, which many clients understand as lowering “cholesterol.”

🍵Clients should be taught to report yellowing of the skin or eyes, because this may signal hepatotoxicity or gallbladder disease, known risks of this medication class.

😴Taking gemfibrozil together with a statin such as atorvastatin significantly increases the risk of myopathy and rhabdomyolysis, so this combination or timing is not recommended.

🚭Clients should be informed that fatigue can occur as a common side effect, and recognizing this helps them know what to expect and when to report more severe symptoms.

📌Core Message

Gemfibrozil is used to improve the lipid profile and can cause liver and gallbladder issues and fatigue, while concurrent timing with statins is generally unsafe due to increased muscle toxicity risk.

Answer 7

Correct Answers:

Bradycardia

Rationale :

🔍Atenolol is a beta₁-selective blocker that slows the heart rate and reduces myocardial oxygen demand.

🧼By blocking beta₁ receptors in the heart, it commonly produces bradycardia, which is an important adverse effect to monitor.

🧵Excessive slowing of the heart can lead to dizziness, hypotension, and syncope, especially in clients with conduction problems.

🧴Nurses must routinely check apical pulse and blood pressure before giving atenolol to detect bradycardia early.

📌Core Message

Atenolol, a beta₁-blocker, commonly causes bradycardia, so heart rate monitoring is essential to detect excessive slowing of the heart.

Answer 8

Correct Answers:

Heart palpitations

Rationale :

🧲Milrinone is an inotrope and vasodilator that increases contractility and cardiac output by inhibiting phosphodiesterase III.

🧷This enhanced contractility and change in electrical activity can predispose clients to ventricular arrhythmias, felt as palpitations.

✍️Because of this proarrhythmic risk, milrinone is usually reserved for short-term use in severe heart failure under close monitoring.

🧾Telemetry and frequent assessments for palpitations, irregular rhythm, or ectopy are critical to detect this serious adverse effect early.

📌Core Message

Milrinone can trigger dangerous arrhythmias, so heart palpitations are a key adverse effect that require immediate assessment and monitoring.

Answer 9

Correct Answers

Blank 1 Correct Option: A productive cough
Blank 2 Correct Option: Thin mucus

Rationale :

🧮Guaifenesin is an expectorant that works by increasing the hydration of respiratory secretions.

🪫It is most useful when a client has a productive cough, because it helps the body clear existing mucus more effectively.

🎯By thinning and loosening mucus, it makes secretions less viscous, so they can be coughed up more easily.

🧘This reduces chest congestion and discomfort, supporting better airway clearance and breathing.

📌Core Message

Guaifenesin is an expectorant used for a productive cough to thin mucus, making it easier to expectorate secretions and relieve congestion.

Answer 10

Correct Answers:

I will take this medication at the same time every day

Rationale :

🧎Montelukast is a leukotriene receptor antagonist used for long-term control of asthma, not for rapid relief of acute attacks.

🚿Taking it at the same time each day helps maintain steady drug levels, which is necessary for ongoing preventive control of symptoms.

🧦Clients should not increase the dose during an acute attack or use it as a rescue medication, because it has a slow onset of action.

🥼Continuing it regularly as prescribed, while using a short-acting bronchodilator for acute episodes, provides the best asthma management strategy.

📌Core Message

Montelukast is a maintenance controller for asthma and should be taken once daily at the same time, while rescue inhalers are used for acute attacks, not extra doses of montelukast.
