RN exams gastrointestinal practice questions set 7

Correct answer:

The correct answer is A. This patient reporting intermittent nausea may have altered nutritional intake, which warrants a referral to the dietitian for a complete nutritional assessment. Nausea can affect food intake and nutrient absorption, potentially leading to malnutrition. Options B, C, and D do not directly indicate a need for a dietitian referral based on the information provided. The patient with rheumatoid arthritis taking prednisone may benefit from dietary interventions, but the information provided does not specify any nutritional concerns. The patient with fluctuating weight gains and losses may have nutritional issues, but further details are needed to justify a dietitian referral. The patient admitted for debridement of an infected wound may have increased nutritional needs due to wound healing, but this alone does not warrant a dietitian referral without additional information on the patient's nutritional status.

Correct answer:

The correct answer is D: Pancreatic abscess. A pancreatic abscess is a serious complication of acute pancreatitis that can lead to sepsis if not promptly drained surgically. Abscess formation occurs when infected necrotic tissue accumulates in the pancreas. Prompt surgical drainage is necessary to prevent the spread of infection and systemic complications. A: Tetany is not a complication of acute pancreatitis that requires surgical drainage to prevent sepsis. Tetany is associated with hypocalcemia, which can occur in pancreatitis but is managed medically. B: Pseudocyst is a common complication of pancreatitis but usually resolves spontaneously or can be managed conservatively unless it becomes infected or causes symptoms. C: Pleural effusion can occur in severe cases of pancreatitis but is managed medically through supportive care and may not always require surgical drainage unless it leads to complications like infection.

Correct answer:

The role of the small intestine's MALT (Mucosa-Associated Lymphoid Tissue) is to prevent bacteria from entering the bloodstream. MALT contains immune cells that help protect the body from harmful pathogens in the gut. When bacteria breach the intestinal barrier, MALT responds by generating an immune response to eliminate the invaders and prevent systemic infection. This function is crucial for maintaining the body's overall health and preventing infections. Choice A (secreting mucus) is incorrect because mucus secretion is primarily performed by goblet cells in the intestine to lubricate and protect the intestinal lining, not by MALT. Choice B (buffering acidic chyme) is incorrect as buffering acidic chyme is mainly done by bicarbonate secreted by the pancreas to neutralize stomach acid, not by MALT. Choice C (activating pepsin) is incorrect as pepsin activation occurs in the stomach, not in the small intestine's MALT.

Correct answer:

The most likely diagnosis for the 50-year-old man with swollen ankles, raised jugular venous pressure, and a history of chronic obstructive pulmonary disease is right heart failure (Choice D). In this case, the patient's symptoms suggest signs of right-sided heart failure, such as peripheral edema and jugular venous distention. Chronic obstructive pulmonary disease can lead to pulmonary hypertension, causing right heart failure. Asthma (Choice A) is primarily a respiratory condition, not typically associated with jugular venous distention or peripheral edema. Congestive heart failure (Choice B) usually presents with features of pulmonary edema and bilateral lower extremity edema, rather than isolated right-sided heart failure. Constrictive pericarditis (Choice C) may present with jugular venous distention, but it is less common compared to right heart failure in a patient with a history of chronic obstructive pulmonary disease.

Correct answer:

The correct answer is B: Test for presence of Chvostek's sign. After a thyroidectomy, tingling around the mouth could indicate hypocalcemia, which can lead to tetany. Chvostek's sign is a test for hypocalcemia, where facial twitching occurs when the facial nerve is tapped. This assessment is crucial to identify potential complications and initiate timely interventions. Incorrect choices: A: Verify the serum potassium level - While electrolyte imbalances can occur post-thyroidectomy, hypocalcemia is more likely to cause the tingling sensation around the mouth. C: Observe for blood on the neck dressing - While assessing for bleeding is important, it does not directly address the tingling sensation reported by the patient. D: Confirm a prescription for thyroid replacement - While important for long-term management post-thyroidectomy, it does not address the immediate concern of tingling sensation related to hypocalcemia.

Correct answer:

The correct answer is D: Obtain serologic studies for antibodies to Trypanosoma cruzi. This patient's presentation is consistent with Chagas disease, caused by Trypanosoma cruzi. The patient is from Brazil, where Chagas disease is endemic. The dilated esophagus and lower esophageal sphincter tapering are classic findings of megaesophagus, a complication of Chagas disease. Serologic studies for antibodies to Trypanosoma cruzi are necessary for definitive diagnosis. Choice A: Refer for partial esophagectomy - Not appropriate as surgery is not indicated without confirming the diagnosis. Choice B: Thick and thin smears of peripheral blood looking for parasites - Not appropriate as Chagas disease is diagnosed through serologic testing, not blood smears. Choice C: Therapeutic trial of a proton pump inhibitor - Not appropriate as the patient's symptoms are likely due to Chagas disease, not gastroesophageal reflux disease.

Correct answer:

The correct answer is D: Pancreatic abscess. A pancreatic abscess is a serious complication of acute pancreatitis that can lead to sepsis if not promptly drained surgically. Abscess formation occurs when infected necrotic tissue accumulates in the pancreas. Prompt surgical drainage is necessary to prevent the spread of infection and systemic complications. A: Tetany is not a complication of acute pancreatitis that requires surgical drainage to prevent sepsis. Tetany is associated with hypocalcemia, which can occur in pancreatitis but is managed medically. B: Pseudocyst is a common complication of pancreatitis but usually resolves spontaneously or can be managed conservatively unless it becomes infected or causes symptoms. C: Pleural effusion can occur in severe cases of pancreatitis but is managed medically through supportive care and may not always require surgical drainage unless it leads to complications like infection.

Correct answer:

The correct answer is C: membrane potential. Membrane potential refers to the difference in electrical charge between the inside and outside of a cell due to the unequal distribution of positively and negatively charged ions across the plasma membrane. This potential difference is crucial for various cellular processes such as nerve conduction and muscle contraction. A: Disequilibrium constant is a term used in chemical reactions to describe the ratio of product concentrations to reactant concentrations at equilibrium, not related to the distribution of charged solutes in a cell. B: Charge separation is a generic term and does not specifically refer to the unequal distribution of charged solutes across the plasma membrane. D: Chemical disequilibrium refers to a state where a system is not at equilibrium in terms of chemical reactions, not directly related to the distribution of charged solutes across the membrane.

Correct answer:

The correct answer is C: Teaching the client to use a folded blanket or pillow to splint the incision. This measure helps support the incision site, reducing pain during coughing and deep breathing. Splinting the incision promotes effective coughing and deep breathing post-surgery, aiding in lung expansion and preventing complications like atelectasis. Explanation of why other choices are incorrect: A: Having the client take rapid, shallow breaths to decrease pain is incorrect as it can lead to inadequate lung expansion and retention of secretions. B: Having the client lay on the left side while coughing and deep breathing is incorrect as it does not directly support the incision site and may not be as effective in reducing pain. D: Withholding pain medication so the client can be alert enough to follow the nurse's instructions is incorrect as pain management is crucial post-surgery for comfort and optimal recovery.
