- A.
Pyrogens
- B.
Histamines
- C.
Leukotrienes
- D.
Catecholamines
Correct Answer
A. PyrogensExplanation
When there is an infection, white blood cells release endogenous chemicals called pyrogens. Pyrogens are substances that can stimulate the hypothalamus in the brain to increase body temperature, resulting in fever. This is a natural response of the immune system to help fight off the infection by creating an unfavorable environment for the pathogens. Histamines, leukotrienes, and catecholamines are not directly involved in producing fever in the presence of infection.Rate this question:

Allergies are acquired following.
- A.
Most bacterial infections
- B.
Initial exposure to an allergen
- C.
Indirect exposure to an allergen
- D.
Repeated exposure to an allergen
Correct Answer
B. Initial exposure to an allergenExplanation
Allergies are acquired following the initial exposure to an allergen. This means that when a person comes into contact with a specific allergen for the first time, their immune system recognizes it as a threat and produces an allergic response. This initial exposure triggers the immune system to create antibodies specific to that allergen. Subsequent exposures to the same allergen can then lead to an allergic reaction as the immune system has already been sensitized to it. Therefore, the correct answer is "initial exposure to an allergen."Rate this question:

Anaerobic metabolism and produces lactic acid
- B.
Aerobic metabolism and produces carbon dioxide
- C.
Fat metabolism and begins producing ketoacids
- D.
Anaerobic metabolism and produces bicarbonate
Correct Answer
A. Anaerobic metabolism and produces lactic acidExplanation
When oxygen does not reach the cell, it undergoes anaerobic metabolism as a backup energy production process. During anaerobic metabolism, the cell breaks down glucose without the presence of oxygen, resulting in the production of lactic acid. This process allows the cell to continue producing energy, although less efficiently than aerobic metabolism. The other options (aerobic metabolism and produces carbon dioxide, fat metabolism and begins producing ketoacids, anaerobic metabolism and produces bicarbonate) are not the correct answers because they do not accurately describe the metabolic process that occurs when oxygen is lacking.Rate this question:

Therefore, their overall safety is improved, leading to a lower likelihood of getting hurt.Rate this question:

Correct Answer
D. Carefully explain what you are doing and frequently talk to the patientExplanation
It is most important to carefully explain what you are doing and frequently talk to the patient. This is because the patient is confused, and providing clear explanations and regular communication can help alleviate their anxiety and confusion. It also helps to establish trust and rapport with the patient, making them feel more comfortable and reassured. Limiting dialogue may further agitate the patient, while sympathizing without providing information may not address their confusion effectively. Asking a family member to apprise the patient may not always be possible or practical in the moment.Rate this question:

Laws, on the other hand, are backed by a legal system that can impose penalties or sanctions on those who violate them, providing a more concrete and enforceable framework for behavior in society.Rate this question:

This scenario depicts abandonment because the patient with a possible fracture of the radius is in need of immediate medical attention, but instead of providing the necessary transportation or arranging for an ambulance, the healthcare provider delays the patient's access to care by arranging for a friend to take them to the emergency department the next day. This delay in treatment can potentially worsen the patient's condition and is considered abandonment as it goes against the duty of care to provide timely and appropriate medical assistance.Rate this question:

D. Maintain the patient's airway, begin artificial respirations, and transport the patient to the closest appropriate medical facilityExplanation
Based on the given scenario, the correct answer is to maintain the patient's airway, begin artificial respirations, and transport the patient to the closest appropriate medical facility. This is because the patient is not breathing and has a rapid carotid pulse, indicating that he needs immediate medical intervention. The charge nurse's information about the patient not wanting to be resuscitated is not sufficient to override the need for life-saving measures. Therefore, the best course of action is to provide artificial respirations and transport the patient to a medical facility for further evaluation and treatment.Rate this question:
