In order to appropriately select the sized OPA, which of the following is necessary?
- Measuring from the corner of the mouth to the earlobe
- Measuring from the center of the mouth to the back of the earlobe
- Measuring from the mouth to the chin
- Measuring from the jaw to the skull base

About This Quiz

The nasopharyngeal airway is also known as an NPA, nasal trumpet due to it's flared end. It is a type of airway adjunct which is tube-like and serves the purpose of creating an alternative breathing outlet to secure an open airway. It is mostly used for patients who have in one way or another lost consciousness. This short quiz is See moreto test your knowledge regarding the use of NPA as well as other aspects related to it.

If a person is found to be unconscious, which of the following is most necessary?
- Placing the person in a good position for CPR
- Beating such a person to startle the heart
- Pouring water on the person to wake him or her up
- Taking off the clothes of such person to allow air
Correct Answer

A. Placing the person in a good position for CPR

Explanation

Placing the person in a good position for CPR is the most necessary action if a person is found to be unconscious. CPR (Cardiopulmonary Resuscitation) is a life-saving technique that involves chest compressions and rescue breaths to maintain blood flow and oxygenation to the vital organs. By placing the person in a good position for CPR, it ensures that the airway is clear and open, allowing effective chest compressions and rescue breaths to be administered. This increases the chances of reviving the person and sustaining their life until medical help arrives.

Which of the following is true?
- Low blood O2 levels influence hypoxic drive
- Hypoxic drive is influenced by CO2 levels
- The leaf-shaped structure located superior to the larynx is the glottis
- Respiration of 20 breathes/min will cause a decreased minute volume in an adult
Correct Answer

A. Low blood O2 levels influence hypoxic drive

Explanation

Low blood O2 levels influence hypoxic drive. Hypoxic drive refers to the body's response to low oxygen levels in the blood, which stimulates an increase in respiratory rate and depth. When blood O2 levels are low, the body senses the need for more oxygen and increases the drive to breathe. This helps to improve oxygenation and maintain homeostasis in the body.

The primary waste product of aerobic metabolism is which of the following?
- Carbon dioxide
- Amino acids
- Pyruvic acid
- Iron
Correct Answer

A. Carbon dioxide

Explanation

During aerobic metabolism, the cells use oxygen to break down glucose and produce energy. The primary waste product of this process is carbon dioxide. Carbon dioxide is produced as a result of the breakdown of glucose molecules in the mitochondria of cells. It is then transported to the lungs through the bloodstream and exhaled from the body. Amino acids are the building blocks of proteins and are not waste products of aerobic metabolism. Pyruvic acid is an intermediate product of glucose metabolism, but it is further processed in the mitochondria to produce energy, so it is not the primary waste product. Iron is a mineral and is not directly related to aerobic metabolism.

Which of the following is the term for the exchange of O2 and CO2 between the alveoli and the blood of the capillaries?
- Ventilation
- Internal respiration
- Ventriculation
- External respiration
Correct Answer

A. External respiration

Explanation

External respiration is the term for the exchange of oxygen (O2) and carbon dioxide (CO2) between the alveoli (air sacs) in the lungs and the blood in the capillaries. This process occurs through diffusion, where oxygen from the alveoli enters the bloodstream and carbon dioxide from the bloodstream enters the alveoli to be exhaled. Ventilation refers to the movement of air in and out of the lungs, while internal respiration refers to the exchange of gases between the blood and body tissues. Ventriculation is not a term related to gas exchange.

The sizes are usually quoted in which of the following?
- Centimeters
- Millimeters
- Inches
- Pentameter
Correct Answer

A. Millimeters

Explanation

The correct answer is millimeters. Millimeters are commonly used to measure sizes, especially in fields such as engineering, manufacturing, and construction. It is a unit of length in the metric system and is equal to one thousandth of a meter. Millimeters provide a more precise measurement compared to centimeters or inches, making them suitable for smaller objects or more accurate calculations. Pentameter, on the other hand, is a unit of poetic meter, not used for measuring sizes.

The outside of the tube is lubricated with what?
- Olive oil
- It has no libricant
- Water-based lubricant
- Chemical-based lubricant
Correct Answer

A. Water-based lubricant

Explanation

The correct answer is water-based lubricant because it is commonly used for lubricating the outside of tubes. Water-based lubricants are preferred in certain applications because they are non-toxic, non-staining, and easily washable. They provide a smooth and slippery surface, reducing friction and allowing for easier movement of the tube.

If the airway is too long, which of the following will not occur?
- It will fail to separate the soft palate from the pharynx
- It can wrongly pass into the larynx
- It can aggravate cough
- It can cause gag reflexes
Correct Answer

A. It will fail to separate the soft palate from the pharynx

Explanation

If the airway is too long, it will fail to separate the soft palate from the pharynx. This is because the soft palate helps to close off the nasal cavity from the oral cavity during swallowing and speech. If the airway is too long, the soft palate will not be able to effectively close off the pharynx, leading to difficulties in swallowing and speech.

The NPA does not prevent which of the following?
- Airway obstruction
- Hypoxia
- Asphyxia
- Anaemia
Correct Answer

A. Anaemia

Explanation

Anaemia is not prevented by the NPA. The NPA, or nasopharyngeal airway, is a medical device used to maintain an open airway and prevent airway obstruction. It helps in ensuring adequate oxygenation and preventing hypoxia, a condition characterized by low oxygen levels in the body. Additionally, the NPA also helps in preventing asphyxia, which is a condition caused by the lack of oxygen and excess of carbon dioxide in the body. However, anaemia is a condition characterized by a decrease in the number of red blood cells or hemoglobin in the blood, and it is not directly prevented by the use of an NPA.

Which of the following doesn't require the use of the NPA in children?
- Congenital maxillofacial abnormalities
- Syndromic craniosynotosis
- Mid-facial hypoplasia
- Scarlet impetigo abnormalities
Correct Answer

A. Scarlet impetigo abnormalities

Explanation

Scarlet impetigo abnormalities do not require the use of the NPA in children. The NPA, or nasopharyngeal airway, is a medical device used to maintain an open airway in patients who are unable to breathe adequately on their own. Scarlet impetigo is a bacterial skin infection that primarily affects the skin and does not directly impact the airway or breathing. Therefore, it does not necessitate the use of an NPA.
