Answer to Question 1

D

Feedback
A In the case of research, regulations identify how protected health information of research subjects is to be managed. The nurse researcher who follows these guidelines is following the ethical principle of protection of subjects.
B Research aspects such as minimizing the risk to participants, allowing reasonable risk to participants in relation to anticipated benefits, and monitoring the research to ensure the safety of participants follow the ethical principle of freedom from harm.
C Confidentiality guarantees that any information provided by the participant will not be reported in any manner that identifies the subject and will not be made accessible to people outside the research team. Describing how confidentiality is maintained is a component of informed consent.
D As a component of informed consent, full and complete information is provided to research subjects about the purpose of the study, procedures, data collection, potential harm and benefits, and alternative methods of treatment.

Answer to Question 2

A
Hypernatremia is diagnosed by elevated serum sodium concentration. Blood pressure is not an accurate indicator of hypernatremia. Emesis and diarrhea will not stop because of intravenous therapy. Urine output is influenced by many factors, including extracellular fluid volume. A large dilute urine output can cause further hypernatremia.
