COLLECTION WITH EXPERT SOLUTIONS
◉ When performing a 12-lead ECG, which of the following positions
demonstrates correct lead placement?
A. V4 is placed left midclavicular 5th intercostal space
B. V5 is paced left midclavicular 4th intercostal space
C. V5 is placed left midaxillary 5th intercostal space
D. V4 is placed left midclavicular 4th intercostal space
Answer: Correct response:
V4 is placed left midclavicular 5th intercostal space
Rationale: The precordial chest lead is positioned at the apex of the
heart, where the apical pulse is auscultated and Point of Maximal
Impulse (PMI) can be felt. V4 is placed on the left midclavicular 5th
intercostal space, at the mitral valve (left ventricular) area.
◉ Which of the following pieces of equipment should the medical
assistant anticipate using when taking a patient's blood pressure?
A. sphygmomanometer
B. pulse oximeter
C. otoscope
D. speculum
,Answer: Correct response:
sphygmomanometer
Rationale: A sphygmomanometer is used to auscultate and measure
blood pressure readings. An otoscope is used to examine the ear, a
speculum is used to examine body cavities, and a pulse oximeter is
used to see what a person's oxygen saturation is in the body.
◉ Which of the following actions should the medical assistant take
first after coming in direct contact with a patient's blood via
needlestick injury?
A. Apply pressure at the site to stop bleeding.
B. Flush the area with water and thoroughly wash it.
C. Obtain the Hep B vaccine if not currently immunized.
D. Inform the patient about the incident.
Answer: Correct response:
Flush the area with water and thoroughly wash it.
Rationale: Immediately after a needlestick injury, wash or clean the
injury at the needle stick site with soap and water and/or flush
mucous membranes. Bleeding could be a good thing, as it serves to
help flush pathogens out rather than keep them in the wound.
Depending on Hepatitis B vaccination status, it might be necessary
to continue the shots (but that would not be the first action after a
needlestick). There would be no need to alarm the patient in this
case. However, it may be necessary to inform the patient later.
,◉ A patient is discharged from the hospital with a diagnosis of HIV
and MRSA and comes to the office for a follow-up appointment.
What is the best method the medical assistant could use to clean the
nasal speculum, forceps, and hemostat used in the exam?
A. disinfect with 70% isopropyl alcohol
B. disinfect with sodium hypochlorite (1:10)
C. chemical sterilization
D. steam sterilization
Answer: Correct response:
steam sterilization
Rationale: All of the instruments here can be cleaned a number of
ways (sanitized, disinfected, and sterilized). Steam sterilization (high
pressure saturated steam in an autoclave) would be the best way to
ensure removal of all HIV/MRSA from the instruments. This will
properly sterilize the instruments without subjecting them to harsh
chemicals. Other medical equipment (i.e. an endoscope) that is not
suitable for the autoclave and must be cleaned based on
manufacturer's instructions and office protocol. These instruments
could be disinfected using a 1:10 sodium hypochlorite solution
(a.k.a. bleach). Bleach is considered safe to use on medical
equipment (though it may pit some metals) and is widely used in
hospitals and clinics to disinfect supplies and counter tops. MRSA
and HIV are both susceptible to the proper dilution of bleach.
However, it is very important to maintain proper contact time
between the bleach and instrument surfaces (or else residual
bacteria and virus could be left behind to infect others). Ethyl
alcohol has been shown to inactivate HIV, but isopropyl alcohol has
, not (making it an inadequate option in this situation). Chemicals
may be effective for disinfection and sterilization, but in turn can be
harsh on instruments. The length of time instruments must remain
immersed in a chemical (i.e. 10 hours for Cidex disinfectant) may
create a potential for damage to the instruments over time.
Chemicals are highly effective and have a definite use in a medical
facility, but the best answer in this case is steam sterilization.
◉ In most cultures in the United States, when a medical assistant is
speaking with a patient, making direct eye contact encourages
A. emotional reasoning
B. a subordinate relationship
C. open communication
D. control of the conversation
Answer: Correct response:
open communication
Rationale: Open communication is the best way to get an honest
exchange with patients. Perceived negative body language may be
viewed as a defense mechanism or communication barrier. If the
patient is relaxed , the communication process will be a more
pleasant exchange. It is advisable to visit without indication of
"control" or "submissive" behavior by either person.
◉ Which of the following forms of medication can be administered
vaginally?
