B) Frequently assessing the mental and neurologic status.
C) Taking daily weights and vital signs.
D) Inducing vomiting.

Question 15

The nurse assesses that the patient's urine has become much more concentrated,which results from the effect of:

A) Adrenaline
B) Aldosterone
C) Antidiuretic hormone (ADH)

Question 16

Each compartment of the body has a water-fluid distribution movement of its own.These fluids move and distribute themselves among these compartments via a process known as:

A) Active transport
B) Diffusion
C) Filtration
D) Osmosis

Question 17

The nurse clarifies that fluid balance is mainly monitored in the body by which two systems?

A) Circulatory and renal
B) Respiratory and circulatory
C) Renal and gastrointestinal

Question 18

The patient's intravenous (IV)injection has been infusing at a very high rate,and now the patient appears to be in fluid volume overload,as indicated by:

A) Hypotension
B) Tachycardia
C) Pulmonary edema
D) Kidney failure

Question 19

A patient has renal damage because of diabetes,which places the patient at risk for:

A) Hypercalcemia
B) Hypocalcemia
C) Hyperkalemia

Question 20

The nurse assists a patient with dyspnea to sit in a high Fowler position.This position allows gravity to help move oxygen from the pulmonary capillaries into the blood by a process known as:

A) Active transport
B) Diffusion
C) Filtration
D) Osmosis

Question 21
