35 practice questions

1. The basic communication model includes:

   1. A. Sender, receiver, and a radio channel
   2. B. Speaker and listener with a shared language
   3. C. Sender, message, receiver, and feedback
   4. D. Transmitter, repeater, and receiving antenna
   Show answer

   Answer: C. Sender, message, receiver, and feedback

   The model has a sender, a message, a receiver, and feedback. Feedback is what tells you the message arrived as intended.

2. Feedback in communication means:

   1. A. Interference that distorts or garbles the radio signal
   2. B. The sender repeating the message more loudly and slowly
   3. C. The receiver's response confirming understanding
   4. D. The written record made after the exchange is complete
   Show answer

   Answer: C. The receiver's response confirming understanding

   Feedback is the receiver's response showing how the message was understood. Asking a patient to repeat instructions back is feedback in practice.

3. Semantic interference occurs when:

   1. A. Two people talk over each other at the same time
   2. B. Words are misunderstood, like unfamiliar jargon
   3. C. A weak radio signal garbles part of the transmission
   4. D. Loud background noise drowns out the speaker's voice
   Show answer

   Answer: B. Words are misunderstood, like unfamiliar jargon

   Semantic interference is a word-meaning problem, such as medical jargon a patient does not know. Plain language solves most of it.

4. Technical interference refers to:

   1. A. Equipment problems like static or dead spots
   2. B. Emotions such as fear that block understanding
   3. C. Word choices the listener cannot interpret
   4. D. Cultural norms that change a message's meaning
   Show answer

   Answer: A. Equipment problems like static or dead spots

   Technical interference includes static, dead spots, or a failing battery. Moving to a different location or channel often fixes it.

5. Nonverbal communication includes:

   1. A. Word choice and sentence structure
   2. B. Written notes and documentation
   3. C. Posture, gestures, eye contact, and tone
   4. D. Only facial expressions and hand gestures
   Show answer

   Answer: C. Posture, gestures, eye contact, and tone

   Nonverbal communication also includes interpersonal distance. Patients read your body language before they hear your words.

6. Studies of communication suggest that:

   1. A. Written content matters far more than delivery style
   2. B. Spoken words carry nearly all of a message's meaning
   3. C. Tone and nonverbal cues carry much of the meaning
   4. D. Nonverbal cues are too unreliable to interpret well
   Show answer

   Answer: C. Tone and nonverbal cues carry much of the meaning

   A large share of meaning travels through tone and nonverbal cues. Your calm posture may reassure more than your explanation.

7. Active listening involves:

   1. A. Full attention, brief encouragers, and confirming
   2. B. Writing down every word the patient says verbatim
   3. C. Planning your next question while the patient speaks
   4. D. Interrupting often to steer toward the key findings
   Show answer

   Answer: A. Full attention, brief encouragers, and confirming

   Active listening means full attention, brief encouragers, and confirming what you heard. It also catches details a distracted listener misses.

8. An open-ended question is best used to:

   1. A. Let the patient describe the problem freely
   2. B. Confirm a specific yes-or-no detail quickly
   3. C. Steer the patient toward a likely diagnosis
   4. D. Speed up the interview on a critical call
   Show answer

   Answer: A. Let the patient describe the problem freely

   Open-ended questions invite the patient to describe the problem in their own words. "What's been going on today?" opens; "Does it hurt here?" closes.

9. A closed-ended question is most appropriate when:

   1. A. You are trying to build rapport early in the call
   2. B. You need specific facts fast from a critical patient
   3. C. You are opening the interview with a stable patient
   4. D. You want the patient to explore their own feelings
   Show answer

   Answer: B. You need specific facts fast from a critical patient

   Critical patients often need short, targeted questions.

10. A leading question is a problem because it:

    1. A. Suggests the expected answer and biases the report
    2. B. Takes too long for the patient to answer fully
    3. C. Only allows the patient a yes or no response
    4. D. Is too general to produce the useful details you need
    Show answer

    Answer: A. Suggests the expected answer and biases the report

    "The pain goes to your left arm, right?" plants an answer and can distort the patient's report.

11. Encoding in the communication model refers to:

    1. A. Receiver interpreting the incoming message
    2. B. Sender turning an idea into words or signals
    3. C. Message passing through the radio channel
    4. D. Receiver replying to confirm understanding
    Show answer

    Answer: B. Sender turning an idea into words or signals

    The sender encodes the idea; the receiver decodes it.

12. Decoding refers to:

    1. A. The sender putting ideas into words
    2. B. Interference distorting the signal
    3. C. The receiver interpreting the message
    4. D. The receiver replying to the sender
    Show answer

    Answer: C. The receiver interpreting the message

    Misinterpretation happens here.

13. Noise in communication means:

    1. A. Only loud sounds in the patient's environment
    2. B. Radio static and other signal problems only
    3. C. Anything that interferes with understanding
    4. D. Silence that leaves gaps in the exchange of ideas
    Show answer

    Answer: C. Anything that interferes with understanding

    Noise is anything that interferes with accurate transmission or understanding. It can be physical, semantic, or psychological.

14. Psychological interference includes:

    1. A. Fear, anger, or bias distorting understanding
    2. B. Static or dropouts on the radio channel mid-call
    3. C. Sirens and traffic noise in the background
    4. D. Medical jargon that the patient does not know
    Show answer

    Answer: A. Fear, anger, or bias distorting understanding

    Fear, anger, prejudice, or distraction all distort understanding. A frightened patient hears less.

15. Cultural interference occurs when:

    1. A. Medical terms are used with a patient who is a layperson
    2. B. Equipment fails in the middle of an important message
    3. C. Differing norms and meanings cause misunderstanding
    4. D. Sender and receiver speak entirely different languages
    Show answer

    Answer: C. Differing norms and meanings cause misunderstanding

    Gestures and eye contact vary by culture; a language difference alone is a separate barrier.

16. Verbal communication includes:

    1. A. Only spoken words
    2. B. Spoken and written words
    3. C. Facial expressions
    4. D. Tone and pitch of voice
    Show answer

    Answer: B. Spoken and written words

    Written reports are verbal communication.

17. Paralanguage refers to:

    1. A. The specific words a speaker chooses
    2. B. Written and typed messages in a report
    3. C. Gestures, posture, and facial expression
    4. D. Tone, pitch, volume, and pace
    Show answer

    Answer: D. Tone, pitch, volume, and pace

    The same words can comfort or threaten.

18. Kinesics refers to:

    1. A. Communication through touch
    2. B. Use of personal space and distance
    3. C. Tone and pitch of the voice
    4. D. Body movements and gestures
    Show answer

    Answer: D. Body movements and gestures

    Posture speaks.

19. Proxemics refers to:

    1. A. Use of personal space
    2. B. Hand gestures and posture
    3. C. Tone and pace of the voice
    4. D. Patterns of eye contact
    Show answer

    Answer: A. Use of personal space

    Entering intimate space without warning alarms patients.

20. Intimate space extends to about:

    1. A. 12 feet
    2. B. 6 feet
    3. C. 4 feet
    4. D. 1.5 feet
    Show answer

    Answer: D. 1.5 feet

    Most patient care happens inside it.

21. Social space, used for interviewing strangers, extends roughly:

    1. A. 1.5 to 4 feet
    2. B. 4 to 12 feet
    3. C. Beyond 12 feet
    4. D. 0 to 1.5 feet

    2. B. Communication through touch
    3. C. Patterns and duration of eye contact
    4. D. Physical distance between two people
    Show answer

    Answer: B. Communication through touch

    A hand on the shoulder can reassure or offend.

23. Congruence in communication means:

    1. A. Repeating key messages for emphasis
    2. B. Using consistent medical terms
    3. C. Speaking at a steady, even volume
    4. D. Verbal and nonverbal messages match
    Show answer

    Answer: D. Verbal and nonverbal messages match

    Patients trust what they see when words and body disagree.

24. A provider saying everything is fine while looking alarmed sends:

    1. A. A clear message that calms the patient
    2. B. A neutral message the patient will likely ignore
    3. C. Reassurance, since the words are positive
    4. D. An incongruent message that erodes trust
    Show answer

    Answer: D. An incongruent message that erodes trust

    Patients read faces. Patients watch faces closely, and when words and expression conflict they tend to believe the expression rather than ignore it.

25. Which open-ended question invites the most information?

    1. A. Does your chest hurt?
    2. B. Is the pain sharp?
    3. C. Tell me what happened today.
    4. D. Did you take your medications?
    Show answer

    Answer: C. Tell me what happened today.

    It lets the patient tell their story.

26. Which closed-ended question is appropriate?

    1. A. What brings you here?
    2. B. Tell me about your history.
    3. C. When did the pain start?
    4. D. How are you feeling?
    Show answer

    Answer: C. When did the pain start?

    It targets a specific fact.

27. Which question is least likely to bias a patient's description of chest pain?

    1. A. "It feels like crushing pressure, doesn't it?"
    2. B. "The pain goes into your left arm, right?"
    3. C. "Can you describe what the pain feels like?"
    4. D. "You're short of breath with it too, aren't you?"
    Show answer

    Answer: C. "Can you describe what the pain feels like?"

    An open, neutral question lets the patient choose the words. Each of the other three is a leading question: it suggests the 'classic' answer, and anxious patients often agree just to be cooperative. That can make an atypical presentation look typical, or the reverse.

28. Stacked questions, asking several at once, cause:

    1. A. More complete descriptions
    2. B. Faster, shorter interviews
    3. C. Confusion and incomplete answers
    4. D. Better recall of related details
    Show answer

    Answer: C. Confusion and incomplete answers

    Ask one at a time.

29. Why questions can be counterproductive because they:

    1. A. Are too open-ended for field use
    2. B. Are too long for frightened patients to follow
    3. C. Limit patients to yes-or-no answers
    4. D. May sound accusatory and cause defensiveness
    Show answer

    Answer: D. May sound accusatory and cause defensiveness

    What led you to wait? works better than why did you wait?

30. A patient who is refusing transport has been told when to call 911 again. Which gives the strongest evidence that she understood?

    1. A. She nods along while you explain each of the instructions
    2. B. She says, "Okay, got it," when you finish explaining
    3. C. She explains in her own words when she should call back
    4. D. She signs the refusal form without asking any questions
    Show answer

    Answer: C. She explains in her own words when she should call back

    Feedback confirms that a message was received as intended. Teach-back, where the patient restates the instructions in her own words, is the strongest form. Nodding and 'okay' are often just politeness. A signature shows she signed, not that she understood.

31. Barriers to communication include:

    1. A. Only radio and equipment failures
    2. B. Noise, language, sensory loss, and emotion
    3. C. Only the patient's emotional state at the time
    4. D. Only language differences between people
    Show answer

    Answer: B. Noise, language, sensory loss, and emotion

    Barriers include noise, language, hearing or vision loss, emotion, culture, and provider behavior. Many are within the provider's control.

32. Jargon is a barrier because it:

    1. A. Is barred from patient care reports
    2. B. Confuses patients and creates distance
    3. C. Is too vague to describe findings precisely
    4. D. Slows the interview down too much
    Show answer

    Answer: B. Confuses patients and creates distance

    Use plain words. Medical terms belong in the written report and are precise among clinicians; the problem is that patients often do not understand them.

33. Interrupting patients early in the interview:

    1. A. Cuts off information and signals disinterest
    2. B. Improves the accuracy of the history
    3. C. Is standard practice on most calls
    4. D. Saves time on critical calls
    Show answer

    Answer: A. Cuts off information and signals disinterest

    Most patients finish their opening statement quickly if allowed.

34. The first impression a patient forms is based on:

    1. A. Your credentials and level of training
    2. B. The equipment and gear you carry in with you
    3. C. The look of the ambulance outside
    4. D. Appearance, approach, tone, and first words
    Show answer

    Answer: D. Appearance, approach, tone, and first words

    It shapes the whole encounter.

35. Communication effectiveness is ultimately measured by:

    1. A. Whether it was understood as intended
    2. B. How loudly and clearly the message is delivered
    3. C. The length of the conversation with the patient
    4. D. The number of precise medical terms used
    Show answer

    Answer: A. Whether it was understood as intended

    Understanding is the goal.
