A nurse is assessing an outbreak of mumps among school-age children. Using the epidemiological triangle, the nurse should recognize that which of the following is the host?
The school
The children
The virus
The vaccine
The Correct Answer is B
The host in the epidemiological triangle is the organism that harbors the disease. In the case of a mumps outbreak among school-age children, the host is the children themselves. The virus (choice C) is the agent that causes the disease, and the vaccine (choice D) is a means of preventing the disease. The school (choice A) is not the host, but it may be the environment where the disease is spreading.

Explanation
A client who expresses fear of experiencing pain near the end may be at risk for suicide. This statement suggests that the client is considering end-of-life issues, which may be a trigger for suicidal ideation. The other statements do not necessarily indicate a risk for suicide. Statement A suggests a desire for control, statement B expresses optimism, and statement C suggests reliance on a partner for support.
Correct Answer is D
Explanation
When reviewing home safety precautions with a client who is to begin radioactive iodine therapy, the nurse should emphasize the importance of using a toilet that is not used by others in the family. The client should also flush the toilet several times after use and clean it with household bleach. The nurse should advise the client to use disposable plates, cups, and utensils and to avoid close contact with others, especially pregnant women and children. The client should also avoid sharing towels, linens, and other personal items. Waiting one week after treatment to use a laxative (choice A) and using cloth handkerchiefs instead of tissues (choice B) are not relevant to home safety precautions for this client. Allowing the granddaughter to visit for four hours daily (choice C) may be unsafe, as the client may still be emitting radiation.
