Reading Passage Question
Gastrostomy tubes are commonly used to provide nutrition and hydration for patients unwilling or unable to maintain an adequate oral intake. Among hospitalized patients aged 65 years or older in the United States, the number undergoing placement of a gastrostomy tube increased from 61000 in 1988 to 121000 in 1995. In 1990 and 1991, roughly one in every hundred hospitalized patients aged 85 years or older received a gastrostomy tube.
The short-term mortality rates following gastrostomy placement are high. In a cohort of more than 7000 American veterans who underwent placement of percutaneous endoscopic gastrostomy tubes between 1990 and 1992, median survival was 7.5 months and 1-year mortality was 59%. Among Medicare beneficiaries receiving gastrostomy tubes in 1991, 30-day and 1-year mortality was 24% and 63%, respectively. Because tube insertion itself is only rarely associated with fatal complications, the high short-term mortality clearly reflects a substantial underlying co-morbidity in this population. Most patients receiving gastrostomy tubes have advanced dementia, other types of severe neurological impairment, cancer, or advanced failure of other internal organs.
The growing use of tube feeding in a population with limited life expectancy inevitably raises the following question: Do physicians discuss the benefits and burdens of tube feeding adequately with patients or surrogate decision-makers before gastrostomy tubes are inserted? Assessing benefits and burdens is an integral part of informed decision-making and should precede any elective life-sustaining intervention. However, anecdotal observations and a recent interview study raise serious questions about the quality of the informed consent process preceding the insertion of gastrostomy tubes.
A small body of literature suggests that fully informed patients or their surrogates might in fact decline permanent tube feeding at a higher-than-expected rate. For example, in the study by Callahan et al, nearly half of the patients undergoing gastrostomy placement (or their surrogates) reported that no alternatives had been discussed before insertion of the tube. O' Brien and colleagues asked 379 mentally competent nursing home residents if they would want a gastrostomy tube if they became unable to eat because of permanent brain damage; only 33% expressed a preference for tube feedings in this circumstance. In an interview study of 121 competent patients with amyotrophic lateral sclerosis, only 28% favored feeding by gastrostomy.

Solutions and Explanation
- The passage is primarily concerned with
(A) the morbidity and mortality rates associated with the use of gastrostomy tubes
(B) the proliferation of the use of gastronomy tubes in patients aged 85 years or older
(C) whether physicians adequately discuss the benefits and burdens of tube feeding with patients or surrogate decision-makers before gastrostomy tubes are inserted
(D) the growing number of patients undergoing placement of a gastrostomy tube
(E) the complications that often follow the insertion of a percutaneous endoscopic gastrostomy tube
Answer: (C)
Explanation: The third option is the right answer. This is because it is discussed in paragraph 4, but if given the option, most patients will reject the GT procedure. The first two paragraphs explain what GT is and the statistics that show that, given a choice, most patients will reject the GT procedure. The remaining options are all wrong choices as they only correspond to a small portion of the passage.
- According to the passage, the high mortality rate following gastrostomy found in research cited in paragraph two is not necessarily a direct result of the placement of a gastrostomy tube because
(A) tube insertion itself is only rarely associated with fatal complications
(B) 30-day and 1-year mortality was 24% and 63% respectively in 1991 among Medicare beneficiaries
(C) only cases in which the percutaneous endoscopic gastrostomy tube was incorrectly place were examined
(D) all the patients in the studies mentioned suffered from life threatening diseases
(E) most of the patients in the studies mentioned suffered from life threatening diseases
Answer: (E)
Explanation: Complex question. One that specifically states that GTs did not lead to a high mortality rate can be the correct answer option. It might also claim that there was another factor contributing to the high mortality rate. Both rings are true. The document makes mention of both. In accordance with this, the final option is the correct answer. The rest of the options are incorrect choices as they are not accurate or have distorted information.
- It can be inferred from the passage that
(A) there are alternatives to the use of gastrostomy tubes to provide nutrition but not hydration for patients unwilling or unable to maintain an adequate oral intake.
(B) there are alternatives to the use of gastrostomy tubes to provide hydration but not nutrition for patients unwilling or unable to maintain an adequate oral intake.
(C) there are alternatives to the use of gastrostomy tubes to provide nutrition and hydration for patients unwilling or unable to maintain an adequate oral intake.
(D) the alternatives to gastrostomy tubes do not provide adequate nutrition and hydration
(E) the alternatives to gastrostomy tubes provide more adequate nutrition and hydration than the gastrostomy tubes
Answer: (C)
Explanation: The best answer is the third option. It might not be mentioned specifically. However, it might be implied. Not a great distance from what the author suggests. The remaining options are completely wrong answers as the statements have no correspondence with the passage. They have no mention in the passage
- The author uses the word “only” [Highlighted] most likely in order to
(A) highlight the oddity of the decision of the patients
(B) emphasize the relatively low percentage of patients that would opt for a gastrostomy tube if given the choice
(C) point out the limited value of inserting a gastrostomy tube
(D) distinguish the primary factor in the decision making process of brain damaged patients
(E) single out a unique merit of gastrostomy tubes for brain damaged patients
Answer: (B)
Explanation: When the study represents a well-informed group, the author uses the word "only" to show that less than a majority (33%) would choose GTs. This is also consistent with the passage's main idea and a fact. That is, given a choice, patients/surrogates would most likely not choose a GT if fully informed about its pros and cons. With this understanding, the second option is the right answer.
