What is the normal resting heart rate range for a healthy adult?
60-100 beats per minute
100-120 beats per minute
120-140 beats per minute
40-60 beats per minute
A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Rates below or above this range may indicate bradycardia or tachycardia respectively.
When measuring blood pressure, the patient's arm should be positioned:
At heart level
Above head level
Extended above elbow level
Below heart level
Positioning the arm at heart level ensures accurate hydrostatic pressure measurement. Arms above or below this level can give falsely low or high readings.
The minimum hand hygiene duration recommended by CDC before patient contact is:
At least 5 seconds
At least 20 seconds
At least 5 minutes
At least 60 seconds
The CDC recommends a minimum of 20 seconds of hand washing with soap and water or alcohol-based hand rub. Shorter durations are not sufficient for effective microbial removal.
How many electrodes are used in a standard 12-lead ECG setup?
10 electrodes
6 electrodes
12 electrodes
8 electrodes
A 12-lead ECG requires 10 physical electrodes: six precordial electrodes and four limb electrodes. The leads are derived from these ten contact points.
Which color tube is most commonly used for a complete blood count (CBC)?
Red top tube
Lavender top tube
Green top tube
Blue top tube
Lavender-top tubes contain EDTA anticoagulant, which preserves blood cells for hematology tests such as a CBC. Other tubes are used for different assays.
A patient's blood pressure reads 138/85 mm Hg. According to current guidelines, this is classified as:
Prehypertension
Normal blood pressure
Stage 2 hypertension
Stage 1 hypertension
Under updated guidelines, systolic 130-139 or diastolic 80-89 mm Hg is Stage 1 hypertension. This classification helps guide early intervention.
To maintain asepsis when changing a surgical wound dressing, which technique should be used?
Wear clean exam gloves
Use nonsterile gloves and disinfect dressing
Clean hands with soap and water only
Wear sterile gloves
Sterile gloves prevent introducing microorganisms into a surgical site. Nonsterile gloves or simple handwashing are insufficient for aseptic wound care.
Where is the V4 chest lead correctly placed during a 12-lead ECG?
Sixth intercostal space at the midclavicular line
Fourth intercostal space at the midaxillary line
Fifth intercostal space at the midclavicular line
Second intercostal space to the right of the sternum
Lead V4 is placed in the fifth intercostal space at the midclavicular line to accurately capture the anterior wall electrical activity. Misplacement can alter ECG interpretation.
How long should a tourniquet be applied before phlebotomy to minimize hemoconcentration?
At least three minutes
No longer than one minute
No longer than five minutes
At least two minutes
Applying a tourniquet for more than one minute can lead to hemoconcentration and spurious lab results. Keeping it under one minute maintains sample integrity.
When should specimen labels be applied during phlebotomy?
Immediately after collection at the bedside
During transport to the lab
Prior to drawing blood
Hours after collection in the lab
Labels must be applied right after collection at the bedside to ensure accurate patient identification and prevent labeling errors. Labeling before or later risks misidentification.
Which section of a patient intake form gathers information about current medications?
Surgical history section
Family history section
Social history section
Medication history section
The medication history section records all current prescriptions and over-the-counter drugs. This information is crucial to avoid interactions and allergies.
What is the recommended method for disposing of a used needle immediately after use?
Break the needle off before disposal
Recap the needle before discarding in the trash
Without recapping, place directly into a puncture-resistant sharps container
Flush the needle in running water before disposal
Needles should never be recapped or broken; they must be placed uncapped into an approved sharps container to reduce needlestick injury risk.
The apical pulse is auscultated at which anatomical location?
Second intercostal space at the sternal border
Fifth intercostal space at the midclavicular line
Third intercostal space at the midaxillary line
Fourth intercostal space at the midclavicular line
The apical pulse is best heard at the fifth intercostal space along the midclavicular line, where the left ventricle is closest to the chest wall.
To protect against splashes of body fluids, which personal protective equipment is essential?
Nonsterile gloves only
Clean lab coat only
Goggles and face shield
Surgical mask only
Goggles or a face shield protect the mucous membranes of the eyes and face from splashes. Masks or gloves alone do not provide full facial protection.
During phlebotomy, a patient becomes dizzy and begins to faint. The first action should be:
Recap the needle and leave the room
Continue the draw slowly
Remove the needle and apply pressure
Encourage the patient to stand up
Removing the needle prevents injury and applying pressure controls bleeding. Leaving the patient standing or continuing the procedure can worsen the situation.
In a 12-lead ECG, if the left and right arm electrodes are inadvertently reversed, which change may appear?
Inverted P waves in lead I
Absence of QRS complexes in lead II
Elevated ST segments across all leads
Peaked T waves in precordial leads
Reversing the limb electrodes for arms flips the polarity of lead I, causing inverted P waves and QRS complexes. Other patterns are unrelated to arm lead reversal.
Calculate the mean arterial pressure (MAP) for a blood pressure reading of 120/80 mm Hg.
Approximately 80 mm Hg
Approximately 93 mm Hg
Approximately 120 mm Hg
Approximately 100 mm Hg
MAP is calculated as (2×diastolic + systolic) / 3. Substituting values gives (2×80 + 120)/3 ≈93 mm Hg, reflecting average arterial pressure.
If a blood sample is labeled as QNS (quantity not sufficient), what is the appropriate next step?
Dilute the sample to increase volume
Send the QNS sample to the lab as is
Reject the entire patient sample without notifying
Recollect the sample with correct volume
A QNS label indicates insufficient volume for accurate analysis. Recollecting ensures adequate quantity and reliable test results.
What is the best method to disinfect a blood culture bottle septum before inoculation?
Wipe quickly with nonsterile glove
Clean with chlorhexidine or alcohol swab and allow to dry
Rinse with sterile water
Submerge the septum in alcohol for 30 seconds
Proper antisepsis requires wiping the septum with an alcohol or chlorhexidine swab and letting it dry to eliminate contaminants. Other methods are insufficient.
During patient intake, which finding would require immediate clinical escalation?
Sudden onset chest pain and dyspnea
Mild seasonal allergies
Occasional headache relieved by rest
Controlled hypertension without changes
Sudden chest pain with dyspnea may indicate a cardiac emergency and needs immediate attention. The other findings are less acute and can be managed routinely.
