CSLB General Building (B) — All Questions

A patient asks why the provider prescribed furosemide. Which drug classification does furosemide belong to?

• a.Anticoagulant
• b.Diuretic✓
• c.Bronchodilator
• d.Antibiotic

Furosemide is a loop diuretic that increases urine output to reduce fluid overload and lower blood pressure, and patients on it often need potassium monitoring. Anticoagulants such as warfarin reduce clot formation. Bronchodilators open airways in asthma and antibiotics treat bacterial infection, so none of those describe furosemide's action.

A patient with chest pain is instructed to place a nitroglycerin tablet under the tongue. What is the main advantage of this route?

• a.Rapid absorption directly into the bloodstream through the mucous membranes, bypassing the digestive tract✓
• b.Slower, more even absorption over 12 hours
• c.It allows the tablet to be chewed and swallowed for better taste
• d.It prevents the medication from entering the bloodstream at all

Sublingual administration lets the drug pass through the rich capillary bed under the tongue directly into the circulation, giving fast relief and avoiding first-pass metabolism in the liver. Extended, even absorption describes transdermal patches or extended-release tablets. Chewing or swallowing a sublingual tablet defeats the route, and the whole purpose is systemic absorption.

A provider orders 0.5 mg of a medication. The tablets on hand are 0.25 mg each. How many tablets should be given?

• a.Half a tablet
• b.One tablet
• c.Three tablets
• d.Two tablets✓

Dividing the desired dose of 0.5 mg by the 0.25 mg strength on hand gives 2 tablets. Half a tablet would deliver only 0.125 mg and one tablet only 0.25 mg, both serious underdoses. Three tablets would deliver 0.75 mg, which exceeds the order by 50 percent.

A child weighs 44 pounds. The provider orders a medication at 10 mg per kilogram per dose. What is the correct single dose?

• a.44 mg
• b.100 mg
• c.200 mg✓
• d.440 mg

Converting weight, 44 pounds divided by 2.2 equals 20 kg, and 20 kg times 10 mg per kg equals 200 mg per dose. Using the weight in pounds without converting yields 440 mg, a dangerous overdose. The 44 mg and 100 mg answers come from skipping the multiplication or using the wrong conversion factor.

Minutes after receiving an injection, a patient develops hives, swelling of the lips, wheezing, and light-headedness. What should the medical assistant do first?

• a.Stay with the patient, call for the provider and emergency help immediately, and prepare to assist with epinephrine per protocol✓
• b.Give the patient a glass of water and observe for 30 minutes
• c.Document the reaction and schedule a follow-up visit for next week
• d.Apply a cold pack to the injection site and send the patient home

Hives, lip swelling, wheezing, and dizziness after an injection suggest anaphylaxis, a life-threatening emergency that requires immediate help and rapid epinephrine administration under the provider's protocol. Water, a cold pack, or a routine follow-up delay definitive treatment while the airway is closing. Documentation is essential but happens after the patient is stabilized.

A patient states, "Penicillin gives me a rash." How should the medical assistant handle this information?

• a.Ignore it because a rash is only a mild side effect
• b.Record it as a documented drug allergy in a prominent place in the record and alert the provider✓
• c.Write it in the free-text visit note only, without flagging the allergy field
• d.Tell the patient that penicillin allergies always disappear with age

Reported drug reactions must be entered in the designated allergy field so the alert follows the patient through prescribing and administration, and the provider should be informed. Burying it in a narrative note or dismissing it risks a repeat exposure that could progress to a severe reaction. Telling a patient an allergy has resolved is a clinical judgment outside the medical assistant's scope.

How must Schedule II controlled substances be handled in a medical office?

• a.Stored in an unlocked cabinet for quick access during emergencies
• b.Counted once a year with no written record required
• c.Stored in a securely locked, substantially constructed cabinet with an accurate inventory and dispensing record maintained✓
• d.Discarded in the regular trash when expired

Federal controlled substance rules require secure storage in a locked, substantially constructed cabinet, accurate records of receipt and dispensing, and periodic inventory of Schedule II drugs. Unlocked storage and annual counts without records invite diversion and violate recordkeeping requirements. Expired controlled substances must be disposed of through an approved method, never in ordinary trash.Controlled Substances Act

Before administering a routine childhood vaccine, what must be given to the parent or guardian?

• a.A copy of the clinic's fee schedule
• b.A prescription for an antipyretic
• c.The manufacturer's shipping invoice for the vaccine lot
• d.The current Vaccine Information Statement for that vaccine✓

Federal law requires that the current Vaccine Information Statement be provided before each dose of a covered vaccine, and the date of the statement and the date it was given must be recorded. A fee schedule or shipping invoice conveys no safety or benefit information to the parent. A prescription for fever medication may be discussed but does not satisfy the legal requirement.National Childhood Vaccine Injury Act

A patient takes warfarin daily. Which instruction is most appropriate for the medical assistant to reinforce?

• a.Double the dose if a headache develops
• b.Keep scheduled blood tests such as INR, report unusual bruising or bleeding, and keep vitamin K intake consistent✓
• c.Stop taking it whenever a cut or scrape occurs
• d.Take an extra dose before dental work to prevent clots

Warfarin requires regular INR monitoring, prompt reporting of unusual bruising or bleeding, and a steady dietary intake of vitamin K, since swings in green leafy vegetables alter the drug's effect. Doubling or adding doses raises bleeding risk sharply. Starting or stopping an anticoagulant is a provider decision, not something a patient should do independently.

Before administering a beta blocker such as metoprolol, which assessment is most important?

• a.Measure the apical pulse and blood pressure, and hold the dose and notify the provider if the pulse is below 60 beats per minute✓
• b.Measure the patient's height and calculate BMI
• c.Check the patient's visual acuity with a Snellen chart
• d.Ask the patient to rate their pain from 0 to 10

Beta blockers slow heart rate and lower blood pressure, so the pulse and blood pressure are checked first and the dose is withheld with provider notification when the pulse falls below about 60 beats per minute. Height, BMI, vision screening, and pain scores do not detect the drug's main risk. Skipping the pulse check can allow dangerous bradycardia.

Which route of administration generally produces the fastest onset of drug action?

• a.Oral tablets swallowed with water
• b.Transdermal patch applied to the chest
• c.Rectal suppository
• d.Intravenous injection✓

Intravenous administration places the drug directly into the bloodstream, so it acts fastest with essentially complete bioavailability. Oral tablets must dissolve and pass through absorption and liver metabolism before acting. Transdermal patches are designed for slow, steady release over hours or days, and rectal absorption is variable and slower than intravenous.

Which statement best distinguishes a side effect from an adverse drug reaction?

• a.A side effect is always life threatening, while an adverse reaction is minor
• b.The two terms describe exactly the same event
• c.A side effect is a known, usually tolerable secondary effect, while an adverse reaction is an unintended, harmful response that may require stopping the drug✓
• d.Only brand-name drugs cause side effects, while generics cause adverse reactions

Side effects are expected secondary effects such as mild drowsiness that patients can often tolerate, while adverse reactions are harmful, unintended responses such as anaphylaxis or organ toxicity that usually require intervention. The severity descriptions in the first choice are reversed. Brand and generic products contain the same active ingredient and can both produce either type of response.

A patient with asthma is prescribed albuterol by metered-dose inhaler. How should the medical assistant describe its purpose?

• a.It is a fast-acting bronchodilator that relaxes airway muscles to relieve wheezing and shortness of breath✓
• b.It is an antibiotic that cures the underlying asthma
• c.It is a long-term sedative that slows breathing
• d.It replaces the need for any other asthma medication permanently

Albuterol is a short-acting bronchodilator that relaxes smooth muscle in the airways, producing rapid relief of wheezing and shortness of breath during an asthma flare. Asthma is not a bacterial infection, so antibiotics have no role. Slowing respiration would worsen an attack, and rescue inhalers do not replace controller medications prescribed for long-term management.

How should most refrigerated vaccines be stored in the clinic?

• a.On the refrigerator door shelf for easy access
• b.In the center of the refrigerator within the manufacturer's recommended temperature range, with temperatures monitored and logged daily✓
• c.At room temperature on the counter until the end of the clinic day
• d.In the freezer, regardless of the manufacturer's instructions

Refrigerated vaccines are stored in the central area of a dedicated unit within the labeled temperature range, with daily temperature monitoring and documentation so excursions are caught early. The door shelf experiences the largest temperature swings each time it opens. Leaving vaccines at room temperature or freezing products not meant to be frozen can inactivate them and require disposal.
