Of the following nerves, which, if any, controls the Larynx during the process of breathing?

Phrenic
Intercostal
Vagus
None of the above

Correct Answer

A. Vagus

Explanation

The vagus nerve controls the larynx during the process of breathing. It is responsible for regulating the muscles that control the vocal cords and the opening and closing of the larynx. The vagus nerve plays a crucial role in coordinating the movements of the larynx during breathing, allowing for proper airflow and vocalization. The other options, phrenic and intercostal nerves, are involved in the mechanics of breathing but do not directly control the larynx. Therefore, the correct answer is Vagus.

In what part of the body is cerebral spinal fluid produced?

Ventricles of the Brain
Spinal Cord
Meninges
Medulla oblongata

Correct Answer

A. Ventricles of the Brain

Explanation

Cerebral spinal fluid is produced in the ventricles of the brain. The ventricles are a system of interconnected cavities filled with cerebrospinal fluid that are located within the brain. These cavities produce and store the cerebral spinal fluid, which serves several important functions such as cushioning the brain and spinal cord, removing waste products, and providing nutrients to the central nervous system. Therefore, the ventricles of the brain are responsible for the production of cerebral spinal fluid.

Dilation of the pupil, a muscular response of the iris, normally occurs as a result of what?

Increased intensity of light
Decreased intensity of light
Irritation to the sclera
Irritation to the conjunctiva

Correct Answer

A. Decreased intensity of light

Explanation

The dilation of the pupil, a muscular response of the iris, normally occurs as a result of decreased intensity of light. When the amount of light entering the eye decreases, the pupil widens to allow more light to enter and improve visibility. This is a protective mechanism of the eye to adapt to different lighting conditions and ensure optimal vision.

What structure(s) of the inner ear provide(s) neural stimuli used to maintain equilibrium?

Fenestra rotunda
Fenestra ovalis
Semicircular canals
Organ of Corti

Correct Answer

A. Semicircular canals

Explanation

The semicircular canals in the inner ear provide neural stimuli used to maintain equilibrium. These canals are filled with fluid and are oriented in three different planes, allowing them to detect changes in head position and movement. When the head moves, the fluid in the canals also moves, which stimulates hair cells in the inner ear. These hair cells then send signals to the brain, which helps to maintain balance and coordination. The fenestra rotunda and fenestra ovalis are openings in the cochlea, and the organ of Corti is responsible for hearing, not equilibrium.

Absortion of food ocurrs prodominantly in which of the following areas of the intestines?

Duodenum
Jejunum
Ileum
Cecum

Correct Answer

A. Ileum

Explanation

The absorption of food occurs predominantly in the ileum. The ileum is the final section of the small intestine and is responsible for the absorption of nutrients, such as vitamins, minerals, and bile salts. It has a large surface area due to the presence of numerous tiny finger-like projections called villi, which increase the absorption capacity. The duodenum is the first section of the small intestine and is primarily responsible for the breakdown of food, while the jejunum is involved in further absorption. The cecum is the beginning of the large intestine and is mainly involved in the absorption of water and electrolytes.

The enzymatic action of amylaze results in the chemical breakdown of

Fats to fatty acids
Starches to fat
Starches to complex sugars
Proteins to complex sugars

Correct Answer

A. Starches to complex sugars

Explanation

Amylase is an enzyme that breaks down starches into simpler sugars. This process is known as hydrolysis, where water molecules are used to break the bonds between the sugar molecules in starch. As a result, complex starch molecules are broken down into smaller, more easily digestible sugar molecules, such as glucose and maltose. Therefore, the correct answer is "starches to complex sugars".

The concepts of the health include

The absence of dicease or disability
Soundness of mind, body, and spirit
Both 1 and 2 above
A feeling of euphoria

Correct Answer

A. Both 1 and 2 above

Explanation

The correct answer is "both 1 and 2 above". This is because the concepts of health include both the absence of disease or disability and the soundness of mind, body, and spirit. These two aspects are often considered essential for overall well-being and a healthy lifestyle. The feeling of euphoria, on the other hand, is not necessarily a requirement for health and can vary from person to person.

Assessing behavior and modifying if appropriate
Educating a patient regarding health and health care
Providing information on how to get to the appropriate clinic for treatment
Obtaining information to determinea patient's illness

Correct Answer

A. Assessing behavior and modifying if appropriate

Explanation

The purpose of therapeutic communication includes educating a patient regarding health and health care, providing information on how to get to the appropriate clinic for treatment, and obtaining information to determine a patient's illness. Assessing behavior and modifying if appropriate is not a purpose of therapeutic communication.

SF-522 Request for Administration of Anesthesia and fo Performance of Operations and other procedures, is normally signed by a parent, legal guardian, or spouse EXCEPT when the patient

Able to do so
Over 16 years of age but under 18
Over 18 years of age but under 21
A member of the Armed Forces

Correct Answer

A. A member of the Armed Forces

Explanation

The SF-522 form is used to request the administration of anesthesia and the performance of operations and procedures. Normally, this form is signed by a parent, legal guardian, or spouse of the patient. However, if the patient is a member of the Armed Forces, they are exempt from having the form signed by someone else. This is because members of the Armed Forces are considered capable of making their own medical decisions and giving consent for anesthesia and procedures.

Unless otherwise directed by the physician, when one is applying a cast to an arm, the patient's wrists is generally in which of the following positions?

Extended about 10 degrees
In the neutral position
Flexed about 30 degrees
In any of the above; specific position is immaterial

Correct Answer

A. In the neutral position

Explanation

When applying a cast to an arm, the patient's wrist is generally in the neutral position. This means that the wrist is neither flexed nor extended, but rather in a straight and natural position. This position helps to ensure proper alignment and support for the arm while the cast is in place.

In the immediate postoperative recovery phase, a patient's skin color may be indicative of all of the following EXCEPT

The patient's ability to recover from the anesthetic agent
Postoperative hemorrhage
Degradation of respiratory function
The development of shock

Correct Answer

A. The patient's ability to recover from the anesthetic agent

Explanation

In the immediate postoperative recovery phase, a patient's skin color may be indicative of postoperative hemorrhage, degradation of respiratory function, or the development of shock. However, it is not indicative of the patient's ability to recover from the anesthetic agent. Skin color changes can be influenced by factors such as blood loss, oxygenation levels, and circulatory status, but not specifically by the patient's ability to metabolize or eliminate the anesthetic agent. Therefore, the patient's ability to recover from the anesthetic agent is not reflected in their skin color.

What source is considered the most frequent reservoir of infectious agents pathogenic to man?

Soil
Animals
Man
Plants

Correct Answer

A. Man

Explanation

The correct answer is "Man" because humans are the most common source of infectious agents that can cause diseases in other humans. This is because humans can carry and transmit various pathogens through direct contact, respiratory droplets, bodily fluids, and other means of transmission. In crowded or unsanitary conditions, the risk of spreading infectious diseases among humans is significantly higher. Therefore, man is considered the most frequent reservoir of infectious agents pathogenic to man.
