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
The nurse is caring for a patient who experiences frequent generalized
A. clonic seizures associated with periods of apne
B. The nurse must be alert
C. base imbalance? -Respiratory acidosis -Respiratory alkalosis -Metabolic alkalosis -Metabolic acidosis Rationale: Seizures may be associated with apnea and thus hypoxemia and lactic acidosis. Lactic acidosis, a form of metabolic acidosis, occurs when cells use glucose without adequate oxygen (anaerobic metabolism); glucose then is incompletely broken
D. This acid releases hydrogen ions, causing acidosis. Lactic acidosis occurs whenever the body has too little oxygen to meet metabolic oxygen
Show answer and rationale
Correct answer: A — clonic seizures associated with periods of apne
Step 1: Clonic seizures are characterized by rhythmic jerking movements.
Step 2: Apnea is the cessation of breathing.
Step 3: Generalized clonic seizures associated with apnea can lead to hypoxemia (low oxygen in the blood).
Step 4: Hypoxemia can result in lactic acidosis due to anaerobic metabolism.
Conclusion: The correct answer is A because the patient experiencing generalized clonic seizures associated with periods of apnea is at risk for hypoxemia and subsequent lactic acidosis.
Summary of other choices:
B: Being alert is important but not directly related to the patient's condition.
C: Base imbalance options are not relevant to the scenario provided.
D: While lactic acidosis is mentioned, this choice does not directly address the association between clonic seizures, apnea, hypoxemia, and lactic acidosis.
Question 2
Define the terms used to describe the delivery of healthcare services
A. Primary, secondary, tertiary care
B. Basic, advanced, emergency care
C. Preventive, diagnostic, therapeutic care
D. Inpatient, outpatient, emergency care
Show answer and rationale
Correct answer: A — Primary, secondary, tertiary care
The correct answer is A: Primary, secondary, tertiary care. Primary care focuses on prevention and basic healthcare needs. Secondary care involves specialized treatment by healthcare professionals like specialists and hospitals. Tertiary care is complex and specialized care typically provided in academic medical centers.
Choice B (Basic, advanced, emergency care) is incorrect because it does not cover the full spectrum of healthcare services like primary, secondary, and tertiary care.
Choice C (Preventive, diagnostic, therapeutic care) is incorrect because it does not encompass the different levels of care provided in the healthcare system.
Choice D (Inpatient, outpatient, emergency care) is incorrect because it only refers to the setting of care rather than the actual levels of healthcare services provided.
Question 3
For which condition is magnetic resonance elastography showing great promise?
A. Gallstones
B. Pancreatic cancer
C. Cholecystitis
D. Cirrhosis of the liver
Show answer and rationale
Correct answer: D — Cirrhosis of the liver
The correct answer is D, Cirrhosis of the liver. Magnetic resonance elastography (MRE) is a non-invasive imaging technique used to assess tissue stiffness, making it ideal for evaluating liver fibrosis in cirrhosis. MRE can accurately detect and quantify liver stiffness, providing valuable information about the progression of cirrhosis and guiding treatment decisions.
Choice A, Gallstones, is incorrect as MRE is not typically used to diagnose this condition. Choice B, Pancreatic cancer, is also incorrect as MRE is not the primary imaging modality for this cancer. Choice C, Cholecystitis, is incorrect because MRE is not commonly used to diagnose inflammation of the gallbladder. In summary, MRE is particularly useful in assessing liver fibrosis in cirrhosis due to its ability to measure tissue stiffness accurately.
Question 4
How should a healthcare provider respond to a parent concerned about their child's sleep pattern?
A. Recommend a sleep study
B. Suggest increasing daytime naps
C. Provide education on sleep hygiene
D. Advise on medication use
Show answer and rationale
Correct answer: C — Provide education on sleep hygiene
When a parent expresses concerns about their child's sleep pattern, providing education on sleep hygiene is a beneficial response. Teaching parents about establishing a consistent sleep routine, creating a conducive sleep environment, and promoting healthy sleep habits can help address the child's sleep issues. This empowers the parent to make positive changes that can improve the child's sleep patterns. Recommending a sleep study (Choice A) may be premature and unnecessary without first addressing basic sleep hygiene. Suggesting increasing daytime naps (Choice B) may not always be appropriate and could further disrupt the child's nighttime sleep. Advising on medication use (Choice D) should be considered only after other non-pharmacological approaches have been tried and if deemed necessary by a healthcare provider.
Question 5
A nurse is planning care for a client who is postoperative and at risk for paralytic ileus. Which of the following interventions should the nurse plan to take to promote peristalsis?
A. Increase ambulation.
B. Decrease fluid intake.
C. Increase protein intake.
D. Offer the client the bedpan every 2 hr.
Show answer and rationale
Correct answer: A — Increase ambulation.
The correct answer is A: Increase ambulation. Ambulation helps stimulate peristalsis by promoting movement in the gastrointestinal tract. This movement aids in preventing or alleviating paralytic ileus, a common postoperative complication. Increasing ambulation helps to increase muscle tone and activity in the intestines, promoting bowel motility.
Summary of other choices:
B: Decrease fluid intake - This is incorrect because adequate hydration is essential for promoting peristalsis and preventing constipation.
C: Increase protein intake - Protein intake is important for wound healing and overall nutrition but does not directly impact peristalsis.
D: Offer the client the bedpan every 2 hr - While providing opportunities for toileting is important, it does not directly promote peristalsis like ambulation does.

Question 6
A patient has been diagnosed with a brain tumor that cannot be removed surgically. During each office visit, the nurse will be assessing the patient for syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following assessments would alert the clinic nurse that the patient may be developing this complication?
A. Complaints that his urine output is decreased, no edema noted in ankles, and increasing headache
B. Elevated blood glucose levels, dry mucous membranes, and severe projectile vomiting
C. Fever, diarrhea, and nausea
D. Muscle cramps, pins and needle sensation around the mouth/lips, and unexplained bruising
Correct answer:
The correct answer is A: Complaints that his urine output is decreased, no edema noted in ankles, and increasing headache.
Rationale:
1. Decreased urine output: SIADH leads to water retention, causing decreased urine output.
2. No edema in ankles: SIADH causes dilutional hyponatremia, not fluid overload like in other conditions causing edema.
3. Increasing headache: Due to cerebral edema from water retention, a common symptom of SIADH.
Summary of incorrect choices:
B: Elevated blood glucose levels, dry mucous membranes, and severe projectile vomiting - These are not typical signs of SIADH.
C: Fever, diarrhea, and nausea - These symptoms are not specific to SIADH.
D: Muscle cramps, pins and needles sensation around the mouth/lips, and unexplained bruising - These are not characteristic symptoms of SIADH.
Which would be true for a county to be defined as having persistent poverty?
A. Population in poverty for over 10 years
B. Population in poverty for over 20 years
C. Population in poverty for over 25 years
D. Population in poverty for over 30 years
Correct answer:
The correct answer is D because persistent poverty refers to a prolonged period of poverty. A county would be defined as having persistent poverty if its population has been in poverty for over 30 years. This timeframe demonstrates a long-standing issue of poverty that has persisted for a significant duration. Choices A, B, and C do not meet the threshold for persistent poverty as they represent shorter durations. Choice A (10 years) and B (20 years) may indicate some level of sustained poverty but do not fully capture the concept of persistent poverty. Choice C (25 years) is closer but still falls short of the extended timeframe required to be considered persistent poverty. Thus, the correct answer is D as it aligns with the definition of persistent poverty as a prolonged period of poverty lasting over 30 years.
Which of the following has contributed to the increasing demand for telehealth services in rural areas?
A. Increased healthcare costs in urban areas
B. High rates of transportation barriers in rural areas
C. Better access to specialized care in rural areas
D. Both A and B
Correct answer:
The correct answer is B: High rates of transportation barriers in rural areas. Telehealth services have become crucial in rural areas due to the challenges of accessing healthcare facilities. Transportation barriers, such as long distances to healthcare providers and lack of public transportation, make it difficult for rural residents to receive timely care. This has led to an increased demand for telehealth services as a convenient and cost-effective solution. Choices A and C are incorrect because increased healthcare costs in urban areas and better access to specialized care in rural areas do not directly contribute to the increasing demand for telehealth services in rural areas. Choice D is also incorrect because only transportation barriers specifically address the unique challenges faced by rural residents.
The major focus of nutritional recommendations in this century has shifted to:
A. prevention and control of chronic diseases.
B. improved sanitation and public health.
C. prevention and control of infectious diseases.
D. development of healthful foods using food technology.
Correct answer:
The correct answer is A: prevention and control of chronic diseases. In this century, nutritional recommendations have increasingly emphasized the importance of preventing and managing chronic diseases like obesity, diabetes, cardiovascular diseases, and cancer. Lifestyle factors such as diet play a significant role in the development of these conditions. Option B, improved sanitation and public health, although important for overall health, is not the primary focus of nutritional recommendations. Option C, prevention and control of infectious diseases, is also crucial but does not reflect the current major focus of nutritional recommendations. Option D, development of healthful foods using food technology, is a valid area of interest but is not the primary shift in focus observed in nutritional recommendations.
Which of these organs is not considered an accessory digestive structure?
A. mouth
B. salivary glands
C. pancreas
D. liver
Correct answer:
The correct answer is A: mouth. The mouth is not considered an accessory digestive structure because it is part of the main digestive system. The mouth is where the process of digestion begins with the mechanical breakdown of food through chewing and the chemical breakdown through the action of saliva produced by salivary glands. The salivary glands, pancreas, and liver are all accessory digestive structures because they aid in the digestion process but are not part of the alimentary canal. Salivary glands produce enzymes to further break down food, the pancreas secretes digestive enzymes and bicarbonate into the small intestine, and the liver produces bile to aid in the digestion and absorption of fats. These organs work alongside the main digestive system to help with the breakdown and absorption of nutrients.
The pancreas secretes a large amount of digestive enzymes after a meal. Which statement about this process is correct?
A. Pepsinogen is the chief enzyme which digests protein and requires removal of a peptide sequence from the active cleft before it can work
B. Pancreatic á-amylase will hydrolyse starch to free glucose
C. Enteropeptidase converts trypsinogen to trypsin by cleavage of a peptide sequence that blocks the active site of trypsin.
D. Pancreatic secretion of hydrochloric acid is required to provide the correct pH for maximal pancreatic enzyme in the duodenum
Correct answer:
Rationale for Correct Answer C:
Enteropeptidase converts trypsinogen to trypsin by cleaving a peptide sequence that blocks the active site of trypsin. This is crucial for the activation of trypsin, a key enzyme in protein digestion. Trypsin then activates other pancreatic enzymes. This process ensures efficient breakdown of proteins in the small intestine.
Summary of Incorrect Choices:
A: Pepsinogen is not secreted by the pancreas and does not require removal of a peptide sequence from the active site for activation.
B: Pancreatic α-amylase is responsible for breaking down starch into maltose and not glucose.
D: Pancreatic secretion of hydrochloric acid is not directly related to the activation of pancreatic enzymes; it is the role of stomach acid to provide an acidic environment for pepsin activation.
How should a caregiver manage a child with a known allergy to peanuts?
A. Avoid all peanut-containing products
B. Encourage regular exposure to peanuts
C. Administer antihistamines daily
D. Recommend peanut-containing supplements
Correct answer:
Avoiding peanut-containing products is crucial for managing a peanut allergy and preventing allergic reactions. Choice B suggesting regular exposure to peanuts can be harmful and trigger severe allergic reactions in a child with a peanut allergy. Regular exposure can increase the risk of anaphylaxis. Choice C of administering antihistamines daily is not a primary prevention strategy and should not be the first-line approach for managing a peanut allergy. Antihistamines only treat symptoms and do not prevent the allergic reaction. Choice D of recommending peanut-containing supplements can also lead to severe allergic reactions and is not recommended for a child with a known peanut allergy. It is essential to eliminate all sources of peanuts to prevent accidental exposure and potential life-threatening reactions.
The nurse is performing an assessment on a client with acute pancreatitis who was admitted to the hospital. Which of the following assessment questions most specifically would elicit information regarding the pain that is associated with acute pancreatitis?
A. Does the pain in your abdomen radiate to your groin.
B. Does the pain in your stomach radiate to the back?
C. Does the pain in your stomach radiate to your lower middle abdomen?
D. Does the pain in your lower abdomen radiate to the hip?
Correct answer:
The correct answer is B: "Does the pain in your stomach radiate to the back?" This question is specific to acute pancreatitis as the pain typically radiates from the epigastric area to the back. Pancreatitis pain often presents as severe, constant, and radiating to the back due to the inflammation of the pancreas affecting surrounding structures.
Choice A is incorrect as the pain in acute pancreatitis typically radiates to the back, not the groin. Choice C is incorrect as it specifies a different area in the abdomen, not the typical location for pancreatitis pain. Choice D is incorrect as pancreatitis pain does not typically radiate to the hip.
In summary, understanding the characteristic radiation of pain in acute pancreatitis is key to assessing and differentiating it from other abdominal conditions.
A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?
A. Refer her for an exploratory laparotomy
B. Measure serum gastrin in response to secretin infusion
C. Treat her for H. pylori
D. Measure gastric acid secretion
Correct answer:
Although the fasting serum gastrin is elevated, this finding alone is insufficient for establishing the diagnosis of gastrinoma. The serum gastrin can be elevated in other conditions, most notably recent therapy with proton-pump inhibitors or H2 antagonists and gastric achlorhydria. In fact, the serum gastrin has been reported to be elevated over 1000 pg/mL in patients with pernicious anemia. Thus, a measurement of basal acid output is required. If the gastric pH is less than 2, the diagnosis of gastrinoma is highly suspicious, and a serum secretin test should be performed. Secretin 2 IU/kg is given over 2 minutes and measurements of the serum gastrin are obtained 2.5, 5, 10, 15, and 30 minutes after infusion. A paradoxical increase in the serum gastrin of greater than 200 pg/mL is diagnostic of Z-E syndrome.
