What Drugs to Study for the HESI Pharmacology Exam

When considering what drugs to study for the HESI Pharmacology Exam, focus on medications commonly used in acute care settings. Priority drug categories include:

Anticoagulants (heparin, warfarin, NOACs)
Cardiovascular drugs (beta-blockers, calcium channel blockers, antiarrhythmics)
Emergency medications (epinephrine, atropine, adenosine)
Antibiotics (especially those given IV)
Pain medications (opioids and non-opioids)
Sedatives and anesthetics
Insulin and other diabetic medications administered IV
Diuretics
Electrolyte replacements (potassium, magnesium, calcium)
Vasopressors and inotropes

For each medication category, know the mechanism of action, indications, contraindications, side effects, nursing considerations, and patient education points.

Sample Questions for HESI IV Medication Test:

Revised Question 1:

A patient is undergoing intravenous heparin therapy. Which lab value is most essential for the nurse to monitor to ensure therapeutic effectiveness?

A) Serum potassium
B) Activated Partial Thromboplastin Time (aPTT)
C) Blood glucose
D) Creatinine

Correct Answer: B) Activated Partial Thromboplastin Time (aPTT)
aPTT is the primary lab test used to evaluate the effectiveness of IV heparin therapy. Heparin affects the intrinsic clotting pathway, and aPTT helps determine if the dose is within the therapeutic range.

A) Serum potassium: Important for general health, especially in cardiac patients, but not directly impacted by heparin.

C) Blood glucose: Relevant for diabetic management, not for monitoring anticoagulation.

D) Creatinine: Assesses kidney function but is more relevant for medications cleared renally; not the key indicator for heparin therapy.

Revised Question 2:

While administering IV vancomycin, a patient reports flushing, itching, and develops a red rash on the upper body. What is the nurse’s priority action?

A) Continue the infusion but slow the rate
B) Stop the infusion immediately
C) Administer the ordered PRN antihistamine
D) Call the pharmacy for an alternative antibiotic

Correct Answer: B) Stop the infusion immediately
These signs are characteristic of Red Man Syndrome, a reaction to rapid vancomycin infusion. The nurse should stop the infusion right away to prevent worsening symptoms.

A) Slow the rate: May help prevent Red Man Syndrome but is not appropriate once symptoms have begun.

C) Administer antihistamine: Might be part of later management, but stopping the drug comes first.

D) Call the pharmacy: Not an immediate priority; the nurse must first address the acute reaction

Important IV Drugs for HESI Nursing Exams

The Important IV Drugs for HESI Nursing Exams span several categories, but certain medications appear more frequently due to their common use in clinical settings. These include:

Anticoagulants:

Heparin
Low molecular weight heparins (enoxaparin)
Direct thrombin inhibitors (bivalirudin)

Cardiovascular Medications:

Cardiotonic glycosides (digoxin)
Antiarrhythmics (amiodarone, lidocaine)
Vasopressors (norepinephrine, dopamine)
Vasodilators (nitroglycerin, nicardipine)

Antimicrobials:

Broad-spectrum antibiotics (piperacillin-tazobactam)
Vancomycin
Aminoglycosides (gentamicin)
Antifungals (fluconazole, amphotericin B)

Critical Care Medications:

Sedatives (propofol, midazolam)
Neuromuscular blockers (vecuronium)
Analgesics (fentanyl, hydromorphone)

For each medication, know the following key elements:

Classification
Mechanism of action
Therapeutic effects
Adverse effects
Nursing considerations
Safe administration practices
Monitoring parameters

Dosage Calculations for IV Meds on the HESI

Dosage Calculations for IV Meds on the HESI form a significant portion of the exam. You should be comfortable calculating:

Drip rates (mL/hr or gtts/min)
Dosages based on patient weight (mg/kg)
Titration adjustments
IV fluid maintenance rates
IV push medication administration times
Converting units (e.g., mg to mcg, pounds to kg)

Here’s a simple formula to remember for drip rate calculations:

Drip rate (mL/hr) = (Dose ordered × Weight × 60 min) ÷ (Concentration × Time in minutes)

Practice these calculations regularly until you can solve them quickly and accurately. Even small errors in IV medication calculations can have serious consequences in real clinical situations.

Clinical Applications

The exam also tests your understanding of the clinical applications of IV pharmacology, including:

Prioritizing assessments for patients receiving specific IV medications
Recognizing signs of adverse reactions
Understanding compatibility issues between IV medications
Knowing appropriate administration techniques (e.g., central line vs. peripheral IV)
Identifying medications requiring special monitoring or administration considerations
