A patient develops food poisoning from contaminated food. The contaminated food would be an example of which part of the infectious cycle?

Infectious agent

Susceptible host

Portal of exit

Reservoir

Answer and Explanation

The Correct Answer is D

The correct answer is D. Reservoir. A reservoir is a source of infection where infectious agents can live and reproduce. In the case of food poisoning, the contaminated food serves as the reservoir of infectious agents, such as bacteria or viruses, that cause the illness. Other examples of reservoirs include animals, soil, water, and contaminated medical equipment. The contaminated food can be a potential source of infection for anyone who consumes it, and it is important to properly handle and prepare food to prevent the spread of illness. By identifying and controlling the source of the infection, such as the contaminated food, healthcare providers can help prevent the spread of infectious diseases.

Correct Answer is A

Explanation

The correct answer is choice A. After inserting the catheter 2-5 cm, the nurse should then inflate the balloon. It is important to confirm urine return before inflating the balloon to ensure that the catheter is in the correct position and has not entered the bladder neck or prostate. Inflating the balloon before confirming urine return can cause trauma and increase the risk of infection. Option B is incorrect because inflating the balloon too early can cause discomfort, trauma and increase the risk of infection. Option C is incorrect because advancing the catheter too far can cause injury to the bladder or ureters. Option D is incorrect because pulling back the catheter after meeting resistance can also cause trauma to the urethra.

A. Serosanguineous B. Sanguinous C. Purulent D. Serous

Correct Answer is B

Explanation

The correct answer is B. Sanguinous. Sanguinous drainage is bright red, indicating fresh bleeding, and may be seen in the first few hours after surgery. Dark red drainage may indicate that there is an increase in bleeding, and the nurse should notify the provider immediately. Serosanguineous drainage is pink in color and consists of both blood and serum. Purulent drainage is thick, yellow or green in color and consists of pus, indicating an infection. Serous drainage is clear or light yellow in color and contains serum without red blood cells.
