Five gastrointestinal questions with answers
Cover the key. Write the first action. Then open the rationale and name why the other choices fail.
Question 1
List the major components of all healthcare systems
A. Facilities, workforce, financing mechanisms
B. Workforce, research, technology
C. Facilities, pharmaceuticals, insurance companies
D. Workforce, clinics, hospitals
Show answer and rationale
Correct answer: A — Facilities, workforce, financing mechanisms
The correct answer is A because facilities, workforce, and financing mechanisms are essential components found in all healthcare systems worldwide. Facilities include hospitals, clinics, and other healthcare settings. Workforce consists of healthcare professionals providing services. Financing mechanisms refer to how healthcare services are paid for.
Choice B (workforce, research, technology) is incorrect because research and technology are important but not universal components of all healthcare systems.
Choice C (facilities, pharmaceuticals, insurance companies) is incorrect because while facilities and insurance companies are common in healthcare systems, pharmaceuticals are not a universal component.
Choice D (workforce, clinics, hospitals) is incorrect as it omits financing mechanisms which are crucial for the functioning of healthcare systems.
Question 2
A lipoprotein has the following components: 5% triglyceride, 20% cholesterol, 30% phospholipid, and 45% protein. This molecule would be best described as a
A. micelle.
B. chylomicron.
C. low-density lipoprotein.
D. high-density lipoprotein.
Show answer and rationale
Correct answer: D — high-density lipoprotein.
The correct answer is D: high-density lipoprotein (HDL). HDL is known to have a higher proportion of protein compared to other lipoproteins. In this case, with 45% protein content, it aligns with the typical composition of HDL. HDL is responsible for transporting cholesterol from peripheral tissues back to the liver for excretion, making it crucial for maintaining cardiovascular health.
A: Micelle is incorrect as it is a single-layered structure formed by amphipathic molecules in a specific environment like bile salts in the intestines.
B: Chylomicron is incorrect as it is primarily composed of triglycerides and is responsible for transporting dietary lipids.
C: Low-density lipoprotein (LDL) is incorrect as it typically has higher cholesterol content compared to HDL and is known as "bad cholesterol" due to its role in depositing cholesterol in arteries.
Question 3
A patient with a history of PUD and a positive H. pylori test is prescribed a combination of antibiotics and a proton pump inhibitor. The patient asks why so many medications are needed. The nurse should explain:
A. Each medication targets a different cause of your ulcer.
B. The medications work together to reduce acid and eliminate the infection.
C. One medication reduces acid, and the others help your stomach heal.
D. The combination ensures that your symptoms will be controlled quickly.
Show answer and rationale
Correct answer: B — The medications work together to reduce acid and eliminate the infection.
Correct Answer: B - The medications work together to reduce acid and eliminate the infection.
Rationale:
1. Antibiotics target and eliminate H. pylori infection, a leading cause of PUD.
2. Proton pump inhibitors reduce gastric acid production, aiding in ulcer healing.
3. Combining antibiotics and PPIs effectively treats both infection and acid production.
4. This comprehensive approach helps resolve the underlying causes of PUD efficiently.
Incorrect Choices:
A: Each medication targets a different cause of your ulcer. - Not accurate as antibiotics and PPIs target infection and acid production.
C: One medication reduces acid, and the others help your stomach heal. - Oversimplifies the treatment process.
D: The combination ensures that your symptoms will be controlled quickly. - Focuses on symptom management rather than addressing the root causes.
Question 4
A nurse is preparing to administer a medication via intramuscular (IM) injection. Which of the following sites is considered the safest for administering an IM injection?
A. The dorsogluteal site
B. The deltoid muscle
C. The ventrogluteal site
D. The vastus lateralis
Show answer and rationale
Correct answer: C — The ventrogluteal site
The ventrogluteal site is considered the safest for IM injections due to the presence of fewer major blood vessels and nerves, reducing the risk of injury. The site is easily accessible and has a thick muscle mass suitable for medication absorption. To locate the ventrogluteal site, the nurse can ask the patient to lie on their side with the knee slightly flexed. The nurse should locate the greater trochanter and iliac crest, forming a V-shaped area where the injection is administered. The other choices are not as safe as the ventrogluteal site. The dorsogluteal site is not recommended due to proximity to the sciatic nerve and major blood vessels. The deltoid muscle is a smaller muscle and may not be suitable for all types of medications. The vastus lateralis site is more commonly used for pediatric patients or adults with limited muscle mass in other areas.
Question 5
Fatty acids and glycerol are released when _____ are broken down by liver or muscle cells.
A. micelles
B. chylomicrons
C. lacteals
D. lipoproteins
Show answer and rationale
Correct answer: B — chylomicrons
The correct answer is B: chylomicrons. Chylomicrons are lipoprotein particles that transport dietary lipids (including fatty acids and glycerol) from the small intestine to the liver or muscle cells for metabolism. When chylomicrons reach the liver or muscles, lipoprotein lipase breaks them down, releasing fatty acids and glycerol for energy production or storage.
Now, let's analyze why the other choices are incorrect:
A: Micelles are small lipid droplets formed in the small intestine to aid in lipid digestion and absorption, but they do not release fatty acids and glycerol when broken down.
C: Lacteals are lymphatic vessels in the small intestine that absorb dietary fats, but they do not release fatty acids and glycerol.
D: Lipoproteins are involved in transporting lipids in the bloodstream but do not release fatty acids and glycerol when broken down.

Question 6
During a long-distance run on a hot day, an athlete produces large quantities of sweat. As a result, the kidneys change the rate of urine production. Why is this change important?
A. Decreased urine production increases the amino acids in the blood.
B. Increased urine production removes amino acids produced as a result of running.
C. Decreased urine production allows the body to conserve water.
D. Increased urine production allows more water to remain in the bloodstream.
Correct answer:
The correct answer is C: Decreased urine production allows the body to conserve water. When an athlete sweats a lot during a long-distance run on a hot day, the body loses water through sweat. To prevent dehydration, the kidneys reduce urine production, allowing the body to retain more water. This helps maintain proper hydration levels and prevent water loss.
Rationale:
A: Decreased urine production does not directly impact amino acids in the blood. Amino acids are primarily regulated by protein metabolism and dietary intake.
B: Increased urine production does not specifically target the removal of amino acids produced during exercise. Amino acids are typically metabolized and used for energy or protein synthesis.
D: Increased urine production does not help more water remain in the bloodstream. Excess water is typically excreted to maintain fluid balance.
What is the fate of any excess glucose that goes to the liver that is not required for energy and not stored as glycogen?
A. it is converted into fat
B. it is converted into protein
C. it is immediately released back into the bloodstream
D. it is degraded
Correct answer:
The correct answer is A: it is converted into fat. Excess glucose not needed for immediate energy or stored as glycogen is converted into fat through a process called de novo lipogenesis in the liver. This occurs when glucose levels are high and glycogen stores are full. The liver converts the excess glucose into fatty acids and then into triglycerides for storage in adipose tissue. This process helps regulate blood glucose levels and prevents hyperglycemia.
Other choices are incorrect:
B: Glucose is not directly converted into protein. Proteins are synthesized from amino acids, not glucose.
C: Releasing excess glucose back into the bloodstream would lead to high blood sugar levels, which is not a typical physiological response.
D: Glucose is not simply degraded; it is either used for energy, stored as glycogen, or converted into fat when in excess.
A 40-year-old man complains of crampy abdominal pain associated with intermittent loose stools for the last three months. He had been healthy until he developed a week of severe diarrhea while visiting India. He then took metronidazole for a week. The diarrhea was resolving by then but evolved soon afterward into his current symptoms. He finds that eating precipitates his symptoms although his weight is stable. Physical examination is unremarkable. Stool microscopy is negative and labs are unrevealing. Which of the following diagnoses is the most likely explanation for his current symptoms?
A. Irritable bowel syndrome
B. Giardiasis
C. Crohn's disease
D. Lactose intolerance
Correct answer:
Postinfectious irritable bowel syndrome is an increasingly recognized form of the disease as several studies have demonstrated that a prior bout of gastroenteritis is found in approximately 10 to $20 \%$ of individuals with IBS. Giardiasis is a common cause of acute infectious diarrhea, and a single stool examination may not be sufficient for the diagnosis, but giardiasis usually resolves within several weeks without becoming a chronic illness and usually clears with metronidazole. Acquired lactose intolerance commonly occurs with intestinal infections but resolves once the infection clears. The onset of Crohn's disease does not typically occur after a bout of gastroenteritis, although intestinal bacteria are thought to fuel inflammation in Crohn's disease and antibiotics, such as ciprofloxacin and metronidazole, are used in the management of the disease.

Sometimes when you are talking and eating you initiate the gagging reflex. The gagging or coughing reflex is stimulated when foreign material enters the larynx. Some of the bolus you are swallowing enters the larynx when you are talking because the
A. epiglottis is not closed over the glottis.
B. soft palate moves inferiorly.
C. pharyngeal constrictor muscles relax.
D. esophageal sphincters relax.
Correct answer:
The correct answer is A: epiglottis is not closed over the glottis. When talking and eating simultaneously, the epiglottis fails to close over the glottis, leading to some of the food or liquid entering the larynx instead of being directed towards the esophagus. The epiglottis normally acts as a lid to cover the larynx during swallowing, preventing food or liquid from entering the airway. Therefore, failure of the epiglottis to close properly during talking and eating can trigger the gagging reflex.
Summary of why the other choices are incorrect:
B: Soft palate moving inferiorly is associated with the process of swallowing and closing off the nasopharynx, not the larynx.
C: Pharyngeal constrictor muscles relax would not lead to food entering the larynx during talking and eating; in fact, they contract to propel food downwards.
D: Esophageal sphinct
When monitoring the food intake of a client with Crohn's disease, the nurse observes that the client does not eat most of the food serve The nurse learns that the client finds the food unappetizing. Which of the following steps should the nurse take to address this issue?
A. Explain to the client the benefits of eating the prescribed food
B. Request the dietitian to suggest more acceptable food
C. Provide the client total parenteral nutrition and lipid infusions
D. Provide the client elemental diet formula and 5-ASA medications
Correct answer:
The correct answer is B. Request the dietitian to suggest more acceptable food. This step is appropriate because it involves seeking help from a professional who can provide tailored dietary recommendations based on the client's preferences and restrictions. The dietitian can work with the client to identify foods that are both appetizing and suitable for managing Crohn's disease.
Explanation for why the other choices are incorrect:
A: Explaining the benefits of eating the prescribed food may not address the client's issue of finding the food unappetizing.
C: Providing total parenteral nutrition and lipid infusions is an extreme measure and should only be considered when all other options have been exhausted.
D: Providing elemental diet formula and 5-ASA medications may not address the client's immediate concern of finding the food unappetizing.
A patient arrives in the ED very hypovolemic related to excretion of 'at least 3 gallon jugs of urine in the past 24 hours.' He describes the urine as being clear-like water. The physician suspects diabetes insipidus. The nurse should be prepared to administer which of the following medications?
A. Desmopressin acetate (DDAVP)
B. Benadryl, an anticholinergic
C. Calcium gluconate
D. Prednisone
Correct answer:
The correct answer is A: Desmopressin acetate (DDAVP). Desmopressin is a synthetic analogue of vasopressin that acts on the kidneys to increase water reabsorption, reducing urine output in diabetes insipidus. This medication helps to concentrate the urine and restore fluid balance in hypovolemic patients.
Choice B: Benadryl is an antihistamine with anticholinergic properties and is not indicated for treating diabetes insipidus.
Choice C: Calcium gluconate is used to treat calcium deficiencies and has no role in managing diabetes insipidus.
Choice D: Prednisone is a corticosteroid used for its anti-inflammatory properties and is not the appropriate treatment for diabetes insipidus.
In summary, Desmopressin (DDAVP) is the correct choice as it directly targets the underlying cause of diabetes insipidus by promoting water reabsorption in the
Which one of the following is the correct pathway of bile from the hepatocytes to the gallbladder?
A. bile canaliculus → hepatic duct → common hepatic duct → common bile duct → gallbladder.
B. bile canaliculus → hepatic duct → cystic duct → common hepatic duct → gallbladder.
C. hepatic sinusoid → central vein → hepatic vein → gall bladder.
D. bile canaliculus → hepatic duct → common hepatic duct → cystic duct → gallbladder.
Correct answer:
The correct answer is D: bile canaliculus → hepatic duct → common hepatic duct → cystic duct → gallbladder. This pathway reflects the anatomical sequence of bile flow from the smallest bile ducts within the liver (bile canaliculi) to the gallbladder. Bile canaliculi collect bile from hepatocytes, which then flows through larger ducts (hepatic duct, common hepatic duct) before reaching the cystic duct, which connects to the gallbladder for bile storage.
Choices A, B, and C are incorrect because they do not follow the correct anatomical pathway of bile flow. For example, in choice A, the common hepatic duct should connect directly to the cystic duct, not the common bile duct. In choice B, the cystic duct should not connect to the common hepatic duct. In choice C, bile does not flow through the central vein or hepatic vein
What is the most important long-term regulator of blood pressure?
A. the baroreceptor reflex
B. urinary output by the kidneys
C. shifting of fluid between the interstitial fluid and plasma
D. the thirst mechanism
Correct answer:
The correct answer is B: urinary output by the kidneys. The kidneys play a crucial role in regulating blood pressure by adjusting the volume of blood in circulation through the control of water and electrolyte balance. Increased urinary output decreases blood volume, leading to a decrease in blood pressure, while decreased urinary output increases blood volume and blood pressure. This long-term regulation mechanism helps maintain blood pressure within a normal range over time.
A: the baroreceptor reflex is a short-term regulator that responds to acute changes in blood pressure.
C: shifting of fluid between interstitial fluid and plasma may affect blood volume temporarily but is not the primary long-term regulator of blood pressure.
D: the thirst mechanism regulates fluid intake to maintain hydration but does not directly regulate blood pressure.
To treat a cirrhotic patient with hepatic encephalopathy, lactulose (Cephulac), rifaximin (Xifaxan), and a proton pump inhibitor are ordere The patient's family wants to know why the laxative is ordere What is the best explanation the nurse can give to the patient's family?
A. It reduces portal venous pressure.
B. It eliminates blood from the GI tract.
C. It traps ammonia and eliminates it in the feces.
D. It decreases bacteria to decrease ammonia formation.
Correct answer:
The correct answer is C: "It traps ammonia and eliminates it in the feces." In hepatic encephalopathy, excessive ammonia levels lead to neurological symptoms. Lactulose works by acidifying the colon, converting ammonia to ammonium, trapping it, and promoting its excretion in feces. This reduces ammonia absorption, alleviating encephalopathy.
Explanation of other choices:
A: Incorrect. Lactulose does not directly reduce portal venous pressure.
B: Incorrect. Lactulose does not eliminate blood from the GI tract.
D: Incorrect. Lactulose does not directly decrease bacteria to reduce ammonia formation.
In summary, the nurse should explain to the patient's family that lactulose helps by trapping ammonia in the GI tract and facilitating its removal in the feces, thus reducing ammonia levels in the body and improving hepatic encephalopathy symptoms.
