    The heart is appears larger in AP than a PA chest x-rays because:

    • The film is closer to the heart

    • The film is farther from the heart

    • The AP x-ray is taken closer to the patient

    • The PA x-ray is taken closer to the patient

    Correct Answer
    A. The AP x-ray is taken closer to the patient
    Explanation
    In an Anteroposterior (AP) chest X-ray, the X-ray source is positioned in front of the patient, while the X-ray detector (film or digital sensor) is placed behind the patient. This configuration places the heart closer to the X-ray source, resulting in a larger heart silhouette on the X-ray image compared to a Posteroanterior (PA) chest X-ray, where the X-ray source is behind the patient, producing a smaller heart image.

    An adult patient is on a pressure controlled ventilation mode.  Suctioning is needed often.  The patient is experiencing repeated bouts of severe coughing, tachypnea, wheezing and is not receiving adequate tidal volumes.  This can be best corrected by:

    • Increasing the diameter of the suction catheter.

    • Changing to a closed system (inline) suction catheter.

    • Increasing the pressure limit.

    • Changing to a volume regulated mode.

    Correct Answer
    A. Changing to a volume regulated mode.
    Explanation
    The patient should be changed from a pressure-cycled to a volume-cycled ventilator to deliver a consistent tidal volume. Changing airway resistance conditions in the patient will result in a pressure-cycled ventilator delivering inconsistent tidal volumes.

    To calculate a patients dead space (VD) without body plethysmography a caregiver needs to know:

    • The change in the amount of Helium.

    • The change in the amount of Nitrogen.

    • The PaCO2

    • The average PetCO2

    • The average PetO2

    Correct Answer(s)
    A. The PaCO2
    A. The average PetCO2
    Explanation
    Arterial carbon dioxide and average exhaled carbon dioxide are needed to calculate the dead space to tidal volume ratio.

    Rate this question:

  • 5. 

    What formula correctly calculates the dead space of a patient

    • (PaCO2 - PetCO2) / PaCO2

    • (PetCO2 - PaCO2) / PetCO2

    • (PaCO2 - PetCO2) / PetCO2

    • (PetCO2 - PaCO2) / PaCO2

    Correct Answer
    A. (PaCO2 - PetCO2) / PaCO2
    Explanation
    The formula (PaCO2 - PetCO2) / PaCO2 correctly calculates the dead space of a patient. Dead space refers to the portion of the respiratory system where no gas exchange occurs, and it is measured by comparing the partial pressure of carbon dioxide (PaCO2) in arterial blood to the partial pressure of end-tidal carbon dioxide (PetCO2), which represents the concentration of carbon dioxide at the end of expiration. Dividing the difference between these two values by the arterial partial pressure of carbon dioxide gives an accurate measurement of dead space.

    The following are true in regards to APRV

    • The expiratory time should be between 0.4 and 0.6 seconds

    • The tidal volume should be between 4ml - 6ml per kg

    • Should have the high pressure set at the mean airway pressure of the previous mode

    • Should start at 28 cmH20 or less if first mode on a patient

    • The low pressure (peep or low CPAP) should be 0 cmH20

    Correct Answer(s)
    A. The expiratory time should be between 0.4 and 0.6 seconds
    A. The tidal volume should be between 4ml - 6ml per kg
    A. Should have the high pressure set at the mean airway pressure of the previous mode
    A. Should start at 28 cmH20 or less if first mode on a patient
    A. The low pressure (peep or low CPAP) should be 0 cmH20
    Explanation
    APRV stands for Airway Pressure Release Ventilation. In APRV, the expiratory time should be between 0.4 and 0.6 seconds, which allows for adequate time for expiration and prevents air trapping. The tidal volume should be between 4ml - 6ml per kg, ensuring adequate ventilation. The high pressure should be set at the mean airway pressure of the previous mode, maintaining consistent pressure levels. If APRV is the first mode used on a patient, it should start at 28 cmH20 or less to avoid excessive pressure. The low pressure, also known as peep or low CPAP, should be 0 cmH20, providing no additional pressure during expiration.

    Which test best diagnosis upper airway obstructions?

    • FEV 1

    • FEV 25%-75%

    • Helium Washout

    • Nitrogen Washout

    • Maximum Expiatory Flow Volume

    Correct Answer
    A. Maximum Expiatory Flow Volume
    Explanation
    The Maximum Expiatory Flow Volume test is the best for diagnosing upper airway obstructions. This test measures the maximum flow rate of air that can be forcefully exhaled after a full inhalation. It provides information about the flow of air through the upper airways, which can be helpful in identifying obstructions such as narrowing or blockages. The other options listed, such as FEV 1, FEV 25%-75%, Helium Washout, and Nitrogen Washout, are not specifically designed to diagnose upper airway obstructions.

    Patients with variable airway compliance and resistance should be placed on what type of ventilation mode?

    • CPAP

    • Pressure Control

    • Volume Control

    Correct Answer
    A. Volume Control
    Explanation
    Ask a pulmonologist.

    A 20-year-old patient is admitted to the ER while having an asthma attack.  She is being treated with 0.63 mg of levalbuterol (Xopenex) by small volume nebulizer. After 45 minutes, the patient's wheezing has decreased in the lower lobes, her respiratory rate has decreased from 32 to 15 per minute, and heart rate has decreased from 120 to 87 beats/min. Based on this information, the physician wants to know what you would recommend.

    • Switch to 2.5 mg Albuterol

    • Decrease the levalbuterol dose to 0.31 mg

    • Continue this dose (0.63) of levalbuterol.

    • Send the patient home after telling them to always use their inhaler

    Correct Answer
    A. Continue this dose (0.63) of levalbuterol.
    Explanation
    Based on the given information, the patient's condition has improved after receiving 0.63 mg of levalbuterol. Her wheezing has decreased, respiratory rate has decreased, and heart rate has also decreased. Therefore, it is recommended to continue with the same dose of levalbuterol (0.63 mg) as it has shown effectiveness in managing the asthma attack. Switching to a higher dose or decreasing the dose may not be necessary at this point. Sending the patient home with instructions to always use their inhaler may not be appropriate as they may still require further observation and treatment in the ER.

    What is the best way to reduce intrapulmonary shunting in ARDS patients while on a ventilator.

    • High FiO2

    • Increase in i Time

    • Decrease in i Tim

    • Carefully adjusting the PEEP to help Oxygenation

    • High Pressures to help Oxygenation

    Correct Answer
    A. Carefully adjusting the PEEP to help Oxygenation
    Explanation
    Carefully adjusting the PEEP (positive end-expiratory pressure) can help improve oxygenation in ARDS (acute respiratory distress syndrome) patients on a ventilator. PEEP is used to keep the alveoli open and prevent collapse during expiration, improving gas exchange. By carefully adjusting the PEEP, the clinician can optimize lung recruitment and oxygenation while minimizing the risk of lung injury. This approach is considered the best way to reduce intrapulmonary shunting, which is the mixing of oxygenated and deoxygenated blood in the lungs, in ARDS patients on a ventilator.
