The _____ duct directly receives the fluids from the gallbladder.
- A. cystic
- B. common bile
- C. hepatic
- D. common hepatic
Correct Answer: A
Rationale: The correct answer is A: cystic duct. The cystic duct directly receives the fluids from the gallbladder and connects it to the common bile duct. The cystic duct is responsible for carrying bile from the gallbladder to the digestive system. Choices B, C, and D are incorrect because the common bile duct carries a mixture of bile from the liver and gallbladder, the hepatic duct connects the liver to the common bile duct, and the common hepatic duct connects the liver to the gallbladder, respectively. Therefore, the cystic duct is the only duct directly receiving fluids from the gallbladder.

Which of these digestive processes occurs in the mouth?
- A. chemical digestion of proteins
- B. mechanical digestion of food
- C. chemical digestion of starch
- D. all of the above
Correct Answer: C
Rationale: The correct answer is C: chemical digestion of starch. In the mouth, salivary glands secrete enzymes like amylase to break down starch into simpler sugars. This process initiates the digestion of carbohydrates. Mechanical digestion (Choice B) occurs in the mouth through chewing and mixing food with saliva, but it does not involve chemical breakdown. Chemical digestion of proteins (Choice A) primarily occurs in the stomach and small intestine with the help of enzymes like pepsin and trypsin. Choice D is incorrect because not all the processes listed occur in the mouth.
Which of the following will have the greatest implication on a client scheduled for a percutaneous liver biopsy?
- A. History of coagulation studies
- B. Allergy to iodine
- C. Family history of GI disorders
- D. Presence of radioactive material in the work environment
Correct Answer: A
Rationale: The correct answer is A: History of coagulation studies. This is because coagulation studies assess the client's ability to form blood clots, which is crucial for a percutaneous liver biopsy to prevent excessive bleeding. It helps determine the risk of bleeding complications during the procedure.
Choice B, Allergy to iodine, is incorrect because an allergy to iodine is more relevant in procedures involving contrast media, not typically in percutaneous liver biopsies.
Choice C, Family history of GI disorders, is incorrect as it does not directly impact the client's safety or outcome during a percutaneous liver biopsy.
Choice D, Presence of radioactive material in the work environment, is also incorrect as it is not directly related to the procedure or its implications on the client's safety during a percutaneous liver biopsy.
The nurse is caring for a patient who returns to the floor at lunchtime after undergoing an upper GI (UGI) series. Which action is most important for the nurse to perform first?
- A. Administer a laxative.
- B. Educate the patient about the possibility of white stools.
- C. Offer the patient a small snack.
- D. Provide oral care.
Correct Answer: A
Rationale: The correct answer is A: Administer a laxative. After an upper GI series, it is important to help the patient eliminate the contrast dye used during the procedure. Administering a laxative will facilitate the removal of the dye from the gastrointestinal tract. This is crucial to prevent any potential complications or adverse effects from the contrast dye.
Explanation for incorrect choices:
B: Educating the patient about the possibility of white stools is not the most immediate concern after an upper GI series. While this information is important for the patient to know, it is not the most urgent action to take.
C: Offering the patient a small snack may be appropriate after the procedure, but ensuring the elimination of the contrast dye through a laxative is more critical.
D: Providing oral care is important for overall patient comfort and hygiene, but it is not the priority immediately following an upper GI series.
A 22-year-old patient calls the outpatient clinic complaining of nausea and vomiting and right lower abdominal pain. What should the nurse advise the patient to do?
- A. Use a heating pad to relax the muscles at the site of the pain.
- B. Drink at least 2 quarts of juice to replace the fluid lost in vomiting.
- C. Take a laxative to empty the bowel before examination at the clinic.
- D. Have the symptoms evaluated by a health care provider right away.
Correct Answer: D
Rationale: The correct answer is D because the patient is experiencing symptoms that could indicate appendicitis, a serious condition that requires immediate medical attention. Nausea, vomiting, and right lower abdominal pain are classic signs of appendicitis. Advising the patient to have the symptoms evaluated by a healthcare provider right away is crucial to prevent potential complications like a ruptured appendix.
Choice A is incorrect because using a heating pad may worsen the condition if it is indeed appendicitis. Choice B is incorrect because drinking juice may not address the underlying cause of the symptoms. Choice C is incorrect because taking a laxative is not recommended as it could potentially aggravate the condition.
In summary, choice D is the correct answer as it prioritizes the patient's health and safety by seeking prompt medical evaluation for the concerning symptoms.
The nurse is educating a patient who is starting treatment with warfarin. Which instruction is most important to include in the teaching plan?
- A. "You can continue taking your aspirin as prescribed."
- B. "Be sure to have regular blood tests to monitor your INR."
- C. "You should increase your intake of vitamin K-rich foods."
- D. "If you miss a dose, double the dose the next day."
Correct Answer: B
Rationale: The correct answer is B: "Be sure to have regular blood tests to monitor your INR." Warfarin is a medication that requires close monitoring of the International Normalized Ratio (INR) to ensure it is within the therapeutic range. Regular blood tests are crucial to prevent complications such as bleeding or blood clots.
Choice A is incorrect because aspirin increases the risk of bleeding when taken with warfarin. Choice C is incorrect because increasing vitamin K-rich foods can interfere with the effectiveness of warfarin. Choice D is incorrect because doubling the dose can lead to an increased risk of bleeding. Regular monitoring of INR levels is essential for safe and effective warfarin therapy.
