The reninangiotensinald osterone system controls fluid volume with aldosterone causing increased reabsorption of sodium and water by the kidneys in an attempt to increase blood volume. The thirst center in the hypothalamus stimulates or inhibits the desire for a person to drink. Antidiuretic hormone (ADH) is released from storage in the posterior pituitary gland as part of the negative feedback mechanism in response to conditions within the cardiovascular system. When ADH is released, urine production is decreased and water reabsorption is increased.
Answer to Question 2
B
Feedback:
Subjective data consist of the client's opinions or feelings about what is happening. Only the client can tell you that he or she is afraid or has pain. Sometimes, the client communicates through body language: gestures, facial expressions, and body posture. Both spoken and written words and body language tell you the client's opinions and feelings. Objective data include all the measurable and observable pieces of information about the client and his or her overall state of health. The term objective means that only precise, accurate measurements or clear descriptions are used. Therefore, other healthcare providers can verify objective data. Restless, pale, diaphoresis, and being very quiet are examples of objective data that the nurse can observe.
