Question 1 of 5
For an organ lying within a body cavity, the tissue which is farthest away from the inner core or lumen of the organ is called the:
Correct Answer: B
Rationale: The correct answer is B: Serosa. The serosa is the outermost layer of an organ lying within a body cavity. It is composed of connective tissue covered by a layer of mesothelium. This layer is farthest away from the inner core or lumen of the organ. The muscularis externa (choice A) is the layer of muscle tissue located just beneath the serosa. The mucosa (choice C) is the innermost layer of the organ, lining the lumen. The myenteric plexus (choice D) is a network of nerve fibers located between the circular and longitudinal layers of the muscularis externa, playing a role in regulating gastrointestinal motility.
Question 2 of 5
A 20-yr-old woman is being admitted with electrolyte disorders of unknown etiology. Which assessment finding is most important to report to the health care provider?
Correct Answer: D
Rationale: The correct answer is D. A serum potassium level of 2.9 mEq/L indicates hypokalemia, which can be life-threatening. Hypokalemia can lead to cardiac arrhythmias and muscle weakness. It is crucial to report this finding promptly to the healthcare provider for immediate intervention. Choice A is relevant but not as urgent as hypokalemia. Choice B is unrelated to electrolyte disorders. Choice C is incomplete and does not provide any relevant information.
Question 3 of 5
The nurse recognizes that teaching a patient following a laparoscopic cholecystectomy has been effective when the patient makes which statement?
Correct Answer: A
Rationale: Rationale for Correct Answer (A): The statement "I can take a shower and walk around the house tomorrow" indicates an understanding of post-operative activity expectations. After a laparoscopic cholecystectomy, early ambulation is encouraged to prevent complications like blood clots. Additionally, showering promotes wound healing and hygiene. Incorrect Choices: B: "I need to limit my activities and not return to work for 4 weeks" - This choice is incorrect as it overestimates the recovery time for a laparoscopic cholecystectomy, which typically allows for a quicker return to normal activities. C: "I can expect yellowish drainage from the incision for a few days" - While drainage is common after surgery, the color and duration mentioned are not typical for this procedure. D: "I will follow a low-fat diet for life because I do not have a gallbladder" - Following a low-fat diet is recommended after surgery, but the statement is too extreme as dietary
Question 4 of 5
Which lymphatic areas are most commonly the site of inflammation?
Correct Answer: B
Rationale: The correct answer is B: palatine tonsils. Palatine tonsils are the most commonly inflamed lymphatic areas due to their location at the back of the throat where they can easily come into contact with pathogens. They play a crucial role in immune defense against infections. Peyer's patches are found in the small intestine and are involved in immune responses to pathogens in the digestive tract. Lingual tonsils are located at the base of the tongue and are less frequently inflamed compared to the palatine tonsils. Adenoids are located in the upper part of the throat behind the nose and are also less commonly inflamed than the palatine tonsils.
Question 5 of 5
The hormone which causes the pancreas to secrete an enzyme-rich fluid is _____.
Correct Answer: A
Rationale: The correct answer is A: cholecystokinin. Cholecystokinin stimulates the pancreas to secrete an enzyme-rich fluid to aid in digestion in response to the presence of fats and proteins in the small intestine. Secretin mainly stimulates bicarbonate secretion from the pancreas. Enterogastrone inhibits gastric emptying. Enterocrinin stimulates the secretion of digestive enzymes from the pancreas and also helps regulate the movements of the intestine.
