1. The body system that functions to maintain fluid balance, support immunity, and contains the spleen is the:

• A. Lymphatic System
• B. Digestive System
• C. Urinary System
• D. Respiratory System

Correct answer: A

Rationale: The Lymphatic System is responsible for maintaining fluid balance and supporting immunity. It contains organs like the spleen, tonsils, thymus, lymph nodes, and lymph vessels. The spleen, a part of the lymphatic system, plays a crucial role in filtering blood and storing blood cells. The Digestive System is primarily involved in the breakdown and absorption of nutrients, not fluid balance or immunity. The Urinary System is responsible for filtering waste products from the blood and regulating fluid balance, but it does not support immunity or contain the spleen. The Respiratory System is focused on gas exchange and oxygenating the blood, not fluid balance or immunity.

2. A patient's urine specimen tested positive for bilirubin. Which of the following is most true?

• A. The patient should be evaluated for kidney disease
• B. The specimen was probably left at room temperature for more than two hours
• C. The specimen is positive for bacteria
• D. The specimen should be stored in an area protected from light

Correct answer: D

Rationale: Bilirubin is easily broken down by light, so all samples testing positive for bilirubin should be protected from light exposure. Storing the specimen in an area protected from light helps maintain the integrity of the bilirubin levels for accurate testing. Choice A is incorrect because the presence of bilirubin in urine does not necessarily indicate kidney disease. Choice B is incorrect as the exposure to light, not room temperature, affects bilirubin levels. Choice C is incorrect as the presence of bilirubin does not indicate the presence of bacteria in the specimen.

3. The client starting an exercise program will progress to walking a 20-minute mile in one month.

• A. Client will walk quickly three times a day
• B. Client will be able to walk a mile
• C. Client will have no alteration in breathing during the walk
• D. Client will progress to walking a 20-minute mile in one month

Correct answer: D

Rationale: Outcome statements must be written in behavioral terms and identify specific, measurable client behaviors. They are stated in terms of the client with an action verb that, under identified conditions, will achieve the desired behavior. Choice A lacks specificity and does not mention a target time or goal. Choice B is vague and does not provide a specific target for improvement. Choice C focuses on a negative outcome (no alteration) rather than a positive goal. The correct answer, Choice D, is specific, measurable, and time-bound, making it a suitable outcome statement for a client starting an exercise program.

4. A healthcare professional is preparing to administer an enteral feeding through a gastrostomy tube. Before administering the feeding, the healthcare professional aspirates some stomach contents and checks the pH. The result is 3.9. What is the next action of the healthcare professional?

• A. Administer the feeding as ordered
• B. Pull the feeding tube out approximately 3 cm
• C. Flush the feeding tube with 60 cc of water
• D. Contact the physician

Correct answer: A

Rationale: When the pH of the aspirated stomach contents is 4 or less, it indicates that the gastrostomy tube is in the stomach, confirming correct placement. A pH of 3.9 falls within this range, so the healthcare professional can proceed with administering the enteral feeding. There is no need to adjust the tube placement, flush with water, or contact the physician in this situation as the tube is appropriately positioned for feeding.

5. In the Gram Stain procedure, which component acts as the mordant?

• A. Crystal violet
• B. Methyl alcohol
• C. Iodine
• D. Safranin

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
