Question 1

During the cardiac cycle, the S2 heart sound indicates the ________ of the ________ valves.

Accepted Answer

The S2 heart sound occurs during diastole, specifically during the closure of the aortic and pulmonic valves, which prevent blood from flowing back into the ventricles. Therefore, choice D is the correct option. Choices A and C are incorrect because they describe the S1 heart sound, which occurs during systole and is caused by the closure of the mitral and tricuspid valves. Choice B is also incorrect because the S2 heart sound does not indicate the opening of any valves during the cardiac cycle.

Question 2

Using your sense of touch to gather information about the patient's condition is called:

Accepted Answer

Palpation is the use of touch to gather information about a patient's condition. Auscultation involves listening to sounds within the body, percussion involves tapping to assess the density of underlying tissues, and inspection involves visual observation.

Question 3

When you ask the patient to puff out her cheeks, show her upper and lower teeth, and raise her eyebrows, which cranial nerve are you evaluating?

Accepted Answer

These actions evaluate the function of the facial nerve (cranial nerve VII). Puffing out the cheeks tests the motor function of the buccinator muscle, showing the upper and lower teeth tests the motor function of the muscles of mastication, and raising the eyebrows tests the motor function of the frontalis muscle.

Question 4

The crunching sound that is made when unlubricated skeletal parts rub against each other is called:

Accepted Answer

The term for the crunching sound made by unlubricated skeletal parts rubbing together is crepitus. Choice A, a synovial rub, is a term for a different phenomenon when the lubricated sacs surrounding joints become inflamed and cause a rubbing sound. Choice B, bursal friction, is another term for an inflamed bursa sac, causing a rubbing sound. Choice D, a pleural friction rub, is a term for a specific medical condition where inflamed or damaged pleura (lining of the lungs) causes a rubbing sound during breathing.

Question 5

Shining a light onto the iris from the lateral side could cause a crescent-shaped shadow on the medial side if the patient is suffering from:

Accepted Answer

Shining a light onto the iris from the lateral side and observing a crescent-shaped shadow on the medial side is indicative of a narrow anterior chamber angle, which is a common sign of angle-closure glaucoma. This shadow is caused by the light being blocked by the iris, which protrudes forward due to the increased pressure in the eye, a characteristic of glaucoma.

Question 6

During ventricular systole, the ventricles contract while the:

Accepted Answer

During ventricular systole, the ventricles contract to pump blood out of the heart. This causes the tricuspid (right atrioventricular) and mitral (left atrioventricular) valves to close to prevent backflow of blood into the atria.

Question 7

Components of a general survey include all of the following EXCEPT:

Accepted Answer

The answer of Components of a general survey include all...

Question 8

A 23-year-old female patient is complaining of lower abdominal and genital pain. Upon examination you find a white, curdlike vaginal discharge. This is most typical of:

Accepted Answer

The white, curdlike vaginal discharge and lower abdominal and genital pain are typical symptoms of candidiasis, an infection caused by the overgrowth of the yeast Candida. Gardnerella (A) can cause a gray, watery discharge with a fishy odor; gonorrhea (B) can cause painful urination and a yellow or green discharge; herpes simplex (D) can cause painful sores on the genitals.

Question 9

You are assessing a 34-year-old female patient who appears to be in hypovolemic shock. You would expect her pulse to be:

Accepted Answer

Hypovolemic shock is caused by decreased blood volume and can result in an increased heart rate in an attempt to compensate for the decreased blood flow. A tachycardic and weak pulse would be expected in hypovolemic shock.

Question 10

To inspect and examine the anus, a paramedic should place the patient in the ________ position.

Accepted Answer

The left lateral recumbent position, also known as the Sims position, is the appropriate position for inspecting and examining the anus. This position helps to expose the anus and provide a clear view of the area. The supine position is lying on the back, which would not be helpful in inspecting the anus. The kneeling position would not provide a clear view of the anus, and the prone position is lying on the stomach, which would not be practical for examining the anus.

Question 11

A tear in the tracheobronchial tree or a pneumothorax can be characterized by ________ in the neck.

Accepted Answer

Subcutaneous emphysema, which is the presence of air under the skin, can be a sign of a tear in the tracheobronchial tree or a pneumothorax. It can cause a characteristic crackling sensation when felt. Swollen lymph nodes, jugular venous distention, or mediastinal deviation, would not be specific to these conditions.

Question 12

When auscultating the posterior chest, you should listen:

Accepted Answer

When auscultating the posterior chest, it is important to listen from side to side as you proceed down the chest to ensure that you cover all lung fields. Listening only at the apices or bases may lead to missing important breath sounds. Also, it is important to listen to both sides simultaneously so that any differences in breath sounds can be easily identified.

Question 13

A patient experienced a brief loss of consciousness following a blow to the head. During your questioning, she describes a series of events that do not match what observers had noted before the trauma. This might be an example of:

Accepted Answer

Confabulation is the production of false, distorted or misinterpreted memories about oneself or the world, without the intention to deceive. In this case, the patient's recollection of events does not match the observations of the witnesses, which suggests that she may be confabulating.

Question 14

A condition that makes posterior chest and lung examination difficult is thoracic:

Accepted Answer

Kyphoscoliosis is a curvature of the spine that can make it difficult to perform posterior chest and lung examinations due to limited mobility and poor chest expansion. Spondylosis and ankylosis refer to the degenerative changes and fusion of the spine, respectively, but they do not typically affect chest examination. Lordosis is an inward curvature of the spine that primarily affects the lower back, so it is also not likely to affect posterior chest examination.

Question 15

A patient who is misinterpreting what is happening is experiencing a(n):

Accepted Answer

An illusion is a misinterpretation of a real external stimulus. This means the patient is incorrectly perceiving something that is actually present in the environment, which differentiates it from hallucinations (perceptions without external stimuli) and delusions (fixed false beliefs). Paresthesia refers to abnormal sensations, such as tingling or prickling, which is unrelated to misinterpretation of events.

Question 16

Which of the following best describes the pulse pressure?

Accepted Answer

Pulse pressure is defined as the difference between systolic and diastolic blood pressures.

Question 17

While you are assessing for Babinski's response, the patient's big toe dorsiflexes and the other toes fan out. This indicates a ________ response, which is ________.

Accepted Answer

The Babinski's response is considered abnormal when the big toe dorsiflexes and the other toes fan out, which is also known as a positive Babinski's sign. A negative Babinski's response is when there is no dorsiflexion of the big toe and the other toes do not fan out, which is considered normal. Therefore, the correct answer is B.

Question 18

Which of the following is included in examination of the mouth?

Accepted Answer

The answer of Which of the following is included in...

Question 19

When checking for skin turgor, you should:

Accepted Answer

Checking skin turgor involves gently picking up a fold of skin, typically on the back of the hand or over the sternum, and then releasing it. This allows you to assess how quickly the skin returns to its normal position, which can be an indicator of dehydration. Option B involves checking for temperature, not skin turgor. Option C involves checking capillary refill, not skin turgor. Option D involves looking for skin flaking, which is not related to skin turgor.

Question 20

Areas of a neurologic exam include all of the following EXCEPT:

Accepted Answer

The cranium is not typically included as an area of the neurologic exam, as it pertains to the structure of the skull rather than the function of the nervous system. The other options - mental status and speech, reflexes, and cranial nerves - are all important components of the neurologic exam.

Quiz 5: Secondary Assessment

During the cardiac cycle, the S2 heart sound indicates the of the valves.
