Certified Nursing Assistant Quiz Part 3

The statement is true because the ovaries are responsible for producing and secreting the female hormones estrogen and progesterone. These hormones play crucial roles in regulating the menstrual cycle, supporting pregnancy, and maintaining overall reproductive health in females.

The central nervous system is made up of the brain and spinal cord. It is responsible for processing and coordinating information received from the senses and sending out instructions to the rest of the body. The brain controls functions such as thinking, memory, and emotions, while the spinal cord serves as a pathway for transmitting signals between the brain and the body. The peripheral nervous system, on the other hand, consists of nerves that connect the central nervous system to the rest of the body. The circulatory system is responsible for the transportation of blood and nutrients throughout the body and is not directly related to the brain and spinal cord.

This statement is false because carriers can indeed pass pathogens to others. Carriers are individuals who are infected with a pathogen but do not show any symptoms. Despite being asymptomatic, carriers can still transmit the pathogen to others through various means such as direct contact, respiratory droplets, or contaminated surfaces. Therefore, it is incorrect to say that a carrier cannot pass a pathogen to others.

The pancreas is an organ in the body that secretes insulin. Insulin is a hormone that helps regulate blood sugar levels. When we eat, the pancreas releases insulin into the bloodstream to help transport glucose from the blood into the cells, where it can be used as energy. Without insulin, the body cannot effectively use glucose, leading to high blood sugar levels and potentially causing diabetes. Therefore, the pancreas plays a crucial role in maintaining proper blood sugar levels by secreting insulin.

A doctor is a medical professional who is trained and licensed to assess, diagnose, and treat diseases and injuries. They have extensive knowledge and expertise in medical science and are able to use various diagnostic tools and techniques to determine the cause of a patient's condition. Doctors also develop treatment plans and prescribe medications or therapies to help patients recover from their illnesses or injuries. They play a crucial role in the healthcare system and work closely with other healthcare professionals to provide comprehensive and effective care to patients.

Leukocytes, also known as white blood cells, play a crucial role in the clotting of blood. They are responsible for initiating the immune response by detecting and attacking foreign substances or pathogens in the body. In the case of an injury or damage to blood vessels, leukocytes are recruited to the site to form a clot and prevent excessive bleeding. This process, known as hemostasis, involves various interactions between different types of blood cells, including leukocytes, platelets, and plasma proteins. Therefore, leukocytes are indeed necessary for the clotting of blood.

The pituitary gland is known as the master gland because it plays a crucial role in regulating and controlling the functions of other endocrine glands in the body. It produces and releases various hormones that influence growth, metabolism, reproduction, and other important bodily processes. The pituitary gland is located at the base of the brain and is connected to the hypothalamus, which helps to control its hormone production. Therefore, the pituitary gland is considered the master gland due to its central role in coordinating the body's hormonal activities.

Wearing eyeglasses does not increase a person's risk for falls. Muscle weakness, memory problems, and joint pain and stiffness can all contribute to an increased risk of falling as they can affect a person's balance and coordination. However, wearing eyeglasses actually improves vision and can help prevent falls by allowing individuals to see clearly and navigate their surroundings more effectively.

Assisted living residents receive housing, help with personal care, and engage in social activities. However, they do not typically receive complex medical care in assisted living facilities. This type of care is usually provided in hospitals or skilled nursing facilities where there is a higher level of medical supervision and expertise.

An arteriole is the smallest branch of an artery. Arterioles are responsible for regulating blood flow and blood pressure in the body. They connect arteries to capillaries, which are even smaller blood vessels where gas exchange and nutrient exchange occur. Veins, on the other hand, carry blood back to the heart and are not the smallest branch of an artery. Therefore, the correct answer is arteriole.

As people age, their digestive system undergoes changes that can lead to decreased peristalsis, which is the wave-like contractions of the muscles in the digestive tract that help move food through the intestines. This decrease in peristalsis can result in slower movement of stool through the intestines, leading to constipation. Chewing problems and swallowing problems may contribute to constipation indirectly by affecting the amount and consistency of food intake. Decreased digestive juices may also contribute to constipation by reducing the efficiency of the digestive process.

The correct answer is "physical changes that are measured and that occur in a steady, orderly manner." This answer accurately describes growth as the process of physical changes that can be observed and quantified, and that happen in a consistent and organized way. It excludes the other options, which refer to different aspects of development such as social and mental changes or the completion of a skill.

Before leaving the room after admitting a new patient, there are several tasks that need to be done. These include filling the water pitcher and cup if oral fluids are allowed, placing the signal light within reach, and lowering the bed to the lowest position. However, raising the bed rails is not necessary before leaving the room. Bed rails are typically raised to ensure patient safety and prevent falls, but they do not need to be raised when leaving the room.

Bile is a digestive fluid produced by the liver and stored in the gallbladder. It is released into the small intestine to aid in the digestion and absorption of fats. It helps in breaking down fats into smaller molecules, making it easier for the body to absorb and utilize them. Therefore, bile is not the substance formed when food mixes with gastric juice to form a semi-liquid substance.

Saying hello from the doorway often is incorrect because it does not promote proper interaction and socialization with the person on contact precautions. It is important to treat the person with kindness and respect, provide hobby materials if possible, and spend as little time in the person's room as possible to minimize the risk of spreading any potential infection.

Presbyopia is the correct answer because it refers to age-related farsightedness. As people age, the lens of the eye becomes less flexible, making it difficult to focus on nearby objects. This condition is commonly known as presbyopia. Dysphagia refers to difficulty swallowing, cataract is a clouding of the eye's lens, and glaucoma is a group of eye conditions that damage the optic nerve. However, none of these conditions specifically relate to age-related farsightedness.

The statement suggests that a clean technique keeps equipment and supplies free of all microbes. However, this is not true as clean technique refers to practices that reduce the number of microbes and prevent the spread of infection, but it does not eliminate all microbes entirely. Therefore, the correct answer is False.

The statement is false because it is not necessary to put on sterile gloves before setting up a sterile field. Sterile gloves are typically worn after the sterile field has been set up, to maintain the sterility of the field while performing procedures within it. The process of setting up a sterile field usually involves cleaning the area, laying down sterile drapes or towels, and arranging sterile instruments and supplies. Sterile gloves are then put on before actually performing any procedures within the sterile field.

Before entering a resident's room who is on contact precautions, it is important to collect all needed equipment. This ensures that the necessary tools and supplies are readily available to properly care for the resident and prevent the spread of infection. By having all the equipment ready, healthcare workers can efficiently and effectively provide the required care while minimizing the risk of contamination.

Isolation precautions are based on clean and dirty practices. Clean practices involve maintaining a clean and hygienic environment, such as hand hygiene, wearing personal protective equipment, and proper disinfection of surfaces. Dirty practices involve handling contaminated items and materials, such as soiled linens or used medical equipment, in a way that prevents the spread of infection. By following clean and dirty practices, healthcare professionals can effectively prevent the transmission of infectious diseases and protect both themselves and their patients.

Transmission-based precautions are not used in the care of all patients and residents. These precautions are only implemented for patients or residents who have known or suspected infections that are spread through specific routes, such as airborne, droplet, or contact transmission. For patients or residents without such infections, standard precautions are typically sufficient to prevent the spread of germs and maintain a safe healthcare environment.
