A nurse is preparing to admit a client who has a new diagnosis of methicillin-resistant Staphylococcus aureus (MRSA). The nurse should plan to place the client in which of the following types of transmission-based precautions?
Contact
Protective
Airborne
Droplet
The Correct Answer is A
Choice A Reason:
Contact precautions are recommended for patients with MRSA to prevent the spread of the bacteria. This includes measures such as placing the patient in a single room, using personal protective equipment (PPE) like gowns and gloves, and ensuring proper hand hygiene. These precautions help to minimize the risk of transmission through direct or indirect contact with the patient or their environment.
Choice B Reason:
Protective precautions, also known as reverse isolation, are used to protect immunocompromised patients from infections. This is not applicable for MRSA patients, as the goal is to prevent the spread of MRSA to others, not to protect the patient from external infections.
Choice C Reason:
Airborne precautions are used for diseases that are transmitted through the air, such as tuberculosis or measles. MRSA is not transmitted through airborne particles, so this type of precaution is not appropriate.
Choice D Reason:
Droplet precautions are used for diseases that are spread through large respiratory droplets, such as influenza or pertussis. MRSA is primarily spread through direct contact, not through respiratory droplets, making droplet precautions unnecessary.

Correct Answer is D
Explanation
Choice A Reason: Try to defecate at different times of the day
This statement is not advisable for clients with constipation. Regularity is key in managing constipation. Encouraging the client to try to defecate at the same time each day can help establish a routine and improve bowel regularity. The body’s natural circadian rhythms can aid in this process, making it easier to have a bowel movement at a consistent time.
Choice B Reason: Consume a low-fiber diet
A low-fiber diet is not recommended for clients with constipation. Fiber adds bulk to the stool and helps it pass more easily through the intestines. Foods high in fiber include fruits, vegetables, whole grains, and legumes. Increasing dietary fiber intake is a common and effective strategy for managing constipation. The recommended daily intake of fiber is 25 grams for women and 38 grams for men.
Choice C Reason: Reduce your daily activity
Reducing daily activity is not beneficial for managing constipation. Physical activity helps stimulate intestinal function and can promote regular bowel movements. Encouraging clients to engage in regular exercise, such as walking, swimming, or yoga, can help alleviate constipation. The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic activity per week.
Choice D Reason: Increase your daily fluid intake
Increasing daily fluid intake is a key recommendation for managing constipation. Fluids help soften the stool, making it easier to pass. Water is the best choice, but other fluids like herbal teas and clear soups can also be beneficial. It is generally recommended to drink at least 8 cups (64 ounces) of water per day, though individual needs may vary based on factors such as age, sex, and activity level.
Correct Answer is A
Explanation
Choice A Reason: Portal of entry
The client’s mouth serves as the portal of entry in the chain of infection. The portal of entry is the route through which an infectious agent enters the host. In the case of hepatitis A, the virus enters the body through the mouth when contaminated food or water is ingested. This link is crucial in the chain of infection as it determines how the pathogen gains access to the host’s body.
Choice B Reason: Susceptible host
A susceptible host is an individual who is at risk of infection due to factors such as a weakened immune system, age, or underlying health conditions. While the client in this scenario may be a susceptible host, the mouth specifically represents the portal of entry, not the host itself.
Choice C Reason: Infectious agent
The infectious agent is the pathogen that causes the disease. In this case, the infectious agent is the hepatitis A virus. The mouth is not the infectious agent but rather the entry point for the virus into the body.
Choice D Reason: Reservoir
A reservoir is the habitat in which the infectious agent normally lives, grows, and multiplies. Common reservoirs include humans, animals, and the environment. The client’s mouth is not a reservoir but the portal of entry for the hepatitis A virus.
