1. The nurse is providing care for a patient with chronic obstructive pulmonary disease. When describing the process of respiration the nurse explains how oxygen and carbon dioxide are exchanged between the pulmonary capillaries and the alveoli. The nurse is describing what process?

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

Correct answer: A

Rationale:

2. A nurse is caring for a client who has just had a central venous access line inserted. Which action should the nurse take next?

A. Begin the prescribed infusion via the new access
B. Ensure an x-ray is completed to confirm placement.
C. Check medication calculations with a second RN.
D. Make sure the solution is appropriate for a central line

Correct answer: B

Rationale:

3. Who would have the greatest percentage of body water?

A. an obese male
B. a nonobese male
C. a nonobese female
D. a newborn

Correct answer: D

Rationale: Newborns have a higher percentage of body water compared to adults due to their higher body fluid content. Factors such as the higher ratio of body surface area to body volume and lower body fat content contribute to this. This is why a newborn would have the greatest percentage of body water. Choices A, B, and C are incorrect because obesity and gender do not determine the percentage of body water in individuals. Therefore, the correct answer is a newborn.

4. A nurse assesses a client who was started on intraperitoneal therapy 5 days ago. The client reports abdominal pain and feeling warm. For which complication of this therapy should the nurse assess this client?

A. Allergic reaction
B. Bowel obstruction
C. Catheter lumen occlusion
D. Infection

Correct answer: D

Rationale:

5. Which of the following is not considered an extracellular fluid?

A. Cerebrospinal fluid
B. The humors of the eye
C. Lymph
D. Cerebrospinal fluid and the humors of the eye

Correct answer: D

Rationale: The correct answer is D. Cerebrospinal fluid and the humors of the eye are not considered extracellular fluids. Extracellular fluids are fluids found outside the cells, such as interstitial fluid and lymph. Cerebrospinal fluid is found within the central nervous system, while the humors of the eye (aqueous humor and vitreous humor) are located within the eyeball, making them distinct from extracellular fluids.
