Question: Water makes up what percentage of the body's composition?
Correct Answer
C. 60 to 70%
Explanation
Water makes up a significant percentage of the body's composition because it is essential for various bodily functions. It helps in maintaining body temperature, transporting nutrients and oxygen, lubricating joints, and removing waste products. The correct answer is 60 to 70% because this range represents the average water content in the human body.
2.
Dehydration can endanger a person's life within:
Correct Answer
A. 24 to 48 hours
Explanation
Dehydration can endanger a person's life within 24 to 48 hours because when the body loses more fluids than it takes in, it can lead to a severe imbalance in electrolytes and impair the normal functioning of vital organs. Without enough water, the body cannot perform essential functions such as regulating body temperature, maintaining blood pressure, and removing waste products. Severe dehydration can quickly lead to complications like organ failure, heatstroke, and even death if not treated promptly. Therefore, it is crucial to address dehydration promptly to prevent life-threatening consequences.
3.
The clearest sign that a person lacks proper hydration is:
Correct Answer
C. Urine output
Explanation
Proper hydration is essential for maintaining the body's fluid balance. When a person lacks proper hydration, their urine output decreases. This is because the body tries to conserve water by reducing the amount of urine produced. Therefore, decreased urine output is a clear sign that a person is not properly hydrated. Dry mouth and excessive thirst can also be signs of dehydration, but they are not as reliable as urine output.
4.
To prevent dehydration the average adult should consume how many cups of water each day?
Correct Answer
C. 9 to 13
Explanation
The average adult should consume 9 to 13 cups of water each day to prevent dehydration. This amount is necessary to maintain proper hydration levels and support bodily functions. Drinking enough water helps to regulate body temperature, lubricate joints, and transport nutrients throughout the body. It also aids in digestion, flushes out toxins, and supports healthy skin. Consuming less than the recommended amount of water can lead to dehydration, which can cause symptoms such as fatigue, dizziness, and dry mouth.
5.
Urinary tract infection: Resident has at least 1 of the following signs and symptoms
Correct Answer
D. All of the above
Explanation
The correct answer is "all of the above" because a urinary tract infection can present with any of the mentioned signs and symptoms. Fever is commonly associated with infections, and increased burning or pain on urination is a common symptom of a urinary tract infection. Additionally, a worsening of mental status can occur in severe cases of urinary tract infection, especially in older adults. Therefore, all of these signs and symptoms can be indicative of a urinary tract infection.
6.
Preventative strategy for urinary tract infections is?
Correct Answer
D. All of the above
Explanation
The correct answer is "All of the above". Adequate hydration helps to flush out bacteria from the urinary tract, reducing the risk of infection. Attention to perineal hygiene, such as wiping from front to back after using the toilet, helps prevent the spread of bacteria to the urethra. Cranberry capsules contain compounds that can prevent E.coli bacteria from adhering to the bladder wall, reducing the likelihood of infection. Therefore, all of these strategies can be used together to prevent urinary tract infections.
7.
Neurogenic bladder is proven factor in contributing to UTI's.
Correct Answer
A. True
Explanation
Neurogenic bladder refers to a condition where there is a dysfunction in the nerves that control the bladder, leading to problems with bladder control. This can result in incomplete emptying of the bladder, urinary retention, or involuntary urine leakage. These issues can increase the risk of urinary tract infections (UTIs) as stagnant urine in the bladder provides a breeding ground for bacteria. Therefore, neurogenic bladder is indeed a proven factor in contributing to UTIs, making the statement true.
8.
Positive urine cultures use the standard confirmation of how many colony-forming units (CFU/ml)?
Correct Answer
C. >100,000
Explanation
Positive urine cultures use the standard confirmation of >100,000 colony-forming units (CFU/ml). This threshold is used to differentiate between significant bacteriuria and contamination. A high number of CFU/ml indicates a true infection, while a lower number may suggest contamination from external sources. Therefore, a positive urine culture is confirmed when the number of CFU/ml exceeds 100,000.
9.
Hands should be washed before and after putting on gloves.
Correct Answer
A. True
Explanation
It is important to wash hands before and after putting on gloves to maintain proper hygiene and prevent the spread of germs. Washing hands before wearing gloves ensures that any existing bacteria or viruses on the hands are removed, reducing the risk of contamination. Similarly, washing hands after removing gloves helps in getting rid of any potential pathogens that may have accumulated on the gloves during use. This practice is particularly crucial in healthcare settings, food handling, and other situations where gloves are used to protect against infection.
10.
A positive culture always means an infection
Correct Answer
B. False
Explanation
The statement "A positive culture always means an infection" is false. A positive culture result indicates the presence of microorganisms in a sample, but it does not necessarily mean that there is an infection. It could simply indicate colonization or contamination. Further clinical evaluation and interpretation are required to determine if the positive culture is indicative of an actual infection or not.
11.
A positive culture should always be treated.
Correct Answer
B. False
Explanation
A positive culture should not always be treated. This statement implies that a positive culture does not require any intervention or action. It suggests that a positive culture should be nurtured and encouraged rather than being treated as a problem or issue. Treating a positive culture may imply that there is something wrong with it, which is not the case. Therefore, the correct answer is False.
12.
Which residents with the following conditions should always be isolated?
Correct Answer
E. C&D
Explanation
Residents with C.diff and Chicken pox should always be isolated. C.diff, also known as Clostridium difficile, is a highly contagious bacterial infection that causes severe diarrhea. Isolation is necessary to prevent the spread of the infection to other residents. Chickenpox, caused by the varicella-zoster virus, is also highly contagious and can easily spread through respiratory droplets. Isolation is necessary to prevent the transmission of the virus to individuals who have not been vaccinated or previously had the disease.

How long should you rub hands together when using alcohol handrub to be effective?
Correct Answer
B. 20 to 30 seconds
Explanation
Rubbing hands together for 20 to 30 seconds when using alcohol handrub is effective because this duration allows enough time for the alcohol to kill the germs on the hands. Rubbing the hands together spreads the handrub evenly and ensures that all surfaces of the hands are covered, including the fingers, nails, and wrists. This duration also allows the alcohol to evaporate completely, leaving the hands clean and dry. Rubbing for a shorter duration may not effectively kill all the germs, while rubbing for a longer duration may lead to unnecessary wastage of the handrub.
14.
How long should you wash hands with soap and water to be effective?
Correct Answer
B. 20 to 30 seconds
Explanation
To effectively wash hands with soap and water, it is recommended to wash for 20 to 30 seconds. This duration allows enough time for the soap to create lather, which helps in removing dirt, germs, and bacteria from the hands. Washing for less than 20 seconds may not be sufficient to clean the hands thoroughly, while washing for more than 30 seconds may not provide any additional benefits in terms of cleanliness. Therefore, washing hands for 20 to 30 seconds strikes a balance between effectiveness and efficiency.
