LPN exams gastrointestinal practice questions set 7

Correct answer:

The correct answer is D because esomeprazole (Nexium) is a proton pump inhibitor that works by decreasing stomach acid production, thereby treating gastroesophageal reflux disease. This explanation is important for the patient to understand the mechanism of action of the medication. Choice A is incorrect because esomeprazole does not increase the rate of gastric emptying; instead, it reduces acid production. Choice B is incorrect because esomeprazole does not neutralize stomach acid immediately; it takes a few days to reach its full effect. Choice C is incorrect because esomeprazole does not coat and protect the stomach and esophagus; it works by reducing acid production. In summary, the correct answer is D because it accurately describes how esomeprazole works to manage recurring heartburn by decreasing stomach acid production, which is essential for treating gastroesophageal reflux disease.

Correct answer:

The correct answer is D: Hepatitis A infection may have a relapsing course. Hepatitis A infection can indeed have a relapsing course, with symptoms recurring after an initial improvement. This is due to the nature of the virus and the immune response. A: Alcoholic hepatitis typically has an AST/ALT ratio less than 2 - This statement is incorrect because in alcoholic hepatitis, the AST/ALT ratio is typically greater than 2. B: Alpha-1 Antitrypsin (A1AT) deficiency is associated with arteriovenous malformations of the brain - This statement is incorrect as A1AT deficiency is primarily associated with pulmonary manifestations such as emphysema and liver disease, not brain arteriovenous malformations. C: Serum A1AT levels are diagnostic of A1AT deficiency - This is incorrect as A1AT levels can be influenced by various factors and genetic testing is needed for a definitive diagnosis of A1AT deficiency

Correct answer:

The correct answer is B: Implicit bias. Implicit bias refers to unconscious attitudes or stereotypes that affect our actions and decisions. In this scenario, the nurse's decision to medicate the Black woman with less potent pain medication compared to the White man with more potent pain medication could be influenced by implicit bias. The nurse may have assumed the Black woman needs less pain relief or may have unconsciously prioritized the White man's pain over hers. This highlights how biases can impact healthcare decisions. Summary: A: Explicit racism is not demonstrated in the scenario as there is no overt discrimination based on race. C: Professional standard of care could be argued, but the unequal treatment based on race suggests bias rather than following professional standards. D: Structural racism involves systemic inequalities, which are not directly evident in this scenario.

Correct answer:

The correct answer is B: Impaired skin integrity related to seepage. This is the priority nursing diagnosis because a colostomy appliance can lead to skin breakdown due to seepage of stool, which can cause irritation and skin breakdown. Maintaining skin integrity is crucial to prevent infection and promote healing. A: Diarrhea is not the priority as it is a common issue after colostomy surgery but can be managed with appropriate interventions. C: Impaired nutrition is not the priority as it is not specifically related to the immediate care of the colostomy appliance. D: Impaired physical mobility is not the priority as it is not directly related to the immediate care of the colostomy appliance. In summary, choice B is the correct answer because maintaining skin integrity is essential for the client's well-being and to prevent complications associated with a colostomy appliance.

Correct answer:

The correct answer is D: Production of cholecystokinin by the duodenum. Cholecystokinin (CCK) is released by the duodenum in response to the presence of fatty acids and amino acids. It stimulates the gallbladder to contract, causing the release of bile into the small intestine to aid in digestion. This is directly related to the patient's symptoms of gallbladder pain after eating, as the contraction of the gallbladder is triggered by CCK. A: Production of bile by the liver is not the mechanism responsible for the gallbladder contraction. B: Production of secretin by the duodenum is involved in regulating the pH of the duodenum, not gallbladder contraction. C: Release of gastrin from the stomach antrum is related to stomach acid secretion, not gallbladder contraction. In summary, the correct answer, D, is directly related to the mechanism responsible for gallbladder pain after eating,

Correct answer:

The Recommended Dietary Allowances (RDAs) are the best measure to describe the amounts of nutrients that should be consumed by the population. RDAs represent the average daily intake level that meets the nutrient requirements of nearly all (97-98%) healthy individuals in a particular life stage and gender group. Choice A, the Dietary Reference Intakes, provide a set of nutrient intake values but do not specifically address the average daily amount of a nutrient considered adequate for practically all individuals. Choice B, the Tolerable Upper Intake levels, focus on the maximum daily amount of a nutrient deemed safe for most healthy people, not the average daily amount needed. Choice C, the Estimated Average Requirements, reflect the average daily amount of a nutrient needed by half of the healthy individuals, which is not as comprehensive as the RDAs that cater to nearly all healthy people.

Correct answer:

The correct answer is D. After a laparoscopic cholecystectomy, the patient typically has up to four small abdominal incisions that are covered with small dressings. This is because laparoscopic cholecystectomy is a minimally invasive procedure involving small incisions, which do not require extensive wound care. The incisions are small and usually heal well with minimal scarring. Explanation for why other choices are incorrect: A: Return to work in 2 to 3 weeks - This is not part of the immediate postoperative plan of care. Patients may need more time to recover before returning to work. B: Be hospitalized for 3 to 5 days postoperatively - Patients undergoing laparoscopic cholecystectomy typically have a shorter hospital stay, usually 1 to 2 days, not 3 to 5 days. C: Have a T-tube placed in the common bile duct to provide bile drainage - This is not typically done after a laparoscopic

Correct answer:

The correct answer is B: Lying on the left side with knees bent. This position allows for better visualization and access to the colon during the colonoscopy procedure. By lying on the left side, the client's colon is in a more optimal position for the scope to navigate through the colon. Additionally, bending the knees helps to relax the abdominal muscles and make the procedure more comfortable for the client. Incorrect choices: A: Lying on the right side with legs straight - This position does not provide optimal access to the colon and may make the procedure more difficult. C: Prone with the torso elevated - This position is not suitable for a colonoscopy as it does not allow for proper access to the colon. D: Bent over with hands touching the floor - This position is not recommended for a colonoscopy as it is not conducive to the procedure and may cause discomfort for the client.

Correct answer:

The correct answer is A: Semiliquid stools with increased fluid requirements. A transverse colostomy is located in the upper part of the colon, where stool consistency is more liquid. This type of colostomy typically produces semiliquid stools due to the shorter transit time in the colon, leading to increased fluid requirements to prevent dehydration. Summary of other choices: B: Liquid stools in a pouch and increased fluid requirements - Incorrect because transverse colostomies produce semiliquid stools, not entirely liquid. C: Formed stools with a pouch, needing irrigation, but no fluid needs - Incorrect as transverse colostomies do not produce formed stools, and fluid intake is necessary. D: Semiformed stools in a pouch with the need to monitor fluid balance - Incorrect because transverse colostomies produce semiliquid stools, not semiformed, and increased fluid intake is needed.

Correct answer:

Rationale for Correct Answer D: - Psyllium is a bulk-forming laxative that works by absorbing water in the intestines, forming a gel-like mass that helps with bowel movements. - Taking large amounts of fluid is essential when using psyllium to prevent the gel-like mass from hardening and causing impaction or bowel obstruction. - Adequate fluid intake is crucial for the safe and effective use of psyllium as a laxative. Summary of Incorrect Choices: - Choice A is incorrect because fiber-containing laxatives like psyllium do not directly impact the absorption of fat-soluble vitamins. - Choice B is incorrect as dietary sources of fiber should not be eliminated entirely but rather balanced to prevent excessive gas. - Choice C is incorrect as all medications, including laxatives, can have potential adverse effects; however, psyllium is generally well-tolerated when used appropriately.
