The nurse is educating a group of older adults on ways to prevent falls. Which statement made by an older adult indicates the need for further teaching?
- A. "I will make sure that I wear my glasses when I walk outside."
- B. "I should make sure my home is free of clutter to prevent tripping."
- C. "I'll make sure I get up slowly from a sitting position to prevent dizziness."
- D. "I won't need to wear shoes in the house since I am only walking a short distance."
Correct Answer: D
Rationale: The correct answer is D. Walking barefoot increases the risk of slipping and falling, especially for older adults with balance issues. Wearing shoes indoors provides stability and reduces the risk of falls. Choices A, B, and C all demonstrate good fall prevention strategies by addressing vision, home safety, and orthostatic hypotension respectively.

Which of these processes occurs in the mouth?
- A. ingestion
- B. mechanical digestion
- C. chemical digestion
- D. all of the above
Correct Answer: D
Rationale: In the mouth, ingestion occurs when food is taken in. Mechanical digestion occurs through chewing and mixing food with saliva. Chemical digestion begins with enzymes in saliva breaking down carbohydrates. Therefore, all processes (ingestion, mechanical digestion, and chemical digestion) occur in the mouth. Other choices are incorrect because they do not encompass all the processes that happen in the mouth.
A client with an ileostomy wants to know why to avoid fibrous vegetables. What should be the nurse's response?
- A. They cause gas formation.
- B. They cause stomal obstruction.
- C. They are difficult to digest.
- D. They increase the risk of diarrhea.
Correct Answer: B
Rationale: The correct answer is B because fibrous vegetables can potentially cause stomal obstruction in clients with an ileostomy due to their indigestible nature, leading to blockages in the stoma. This can result in severe complications and require medical intervention. Gas formation (choice A) is a common issue with high-fiber foods but is not specific to fibrous vegetables. Fibrous vegetables are not necessarily difficult to digest (choice C) for most individuals, although they may be harder for those with reduced gut function. While fibrous vegetables may contribute to loose stools, they do not directly increase the risk of diarrhea (choice D) in the same way they can cause stomal obstruction.
The hydrogen ions that form hydrochloric acid of the stomach come from
- A. lactic acid.
- B. carbonic acid.
- C. citric acid.
- D. acetic acid.
Correct Answer: B
Rationale: The correct answer is B: carbonic acid. Carbonic acid is produced when carbon dioxide reacts with water in the stomach, forming hydrogen ions that combine with chloride ions to create hydrochloric acid. Lactic acid (A), citric acid (C), and acetic acid (D) do not directly contribute to the formation of hydrochloric acid in the stomach. Therefore, they are incorrect choices for this question.
The optimum pH for trypsin and chymotrypsin is about
- A. 1-3.
- B. 5-7.
- C. 7-9.
- D. 10-12.
Correct Answer: C
Rationale: The correct answer is C (7-9) because trypsin and chymotrypsin are proteolytic enzymes that function optimally in slightly basic environments. At pH 7-9, these enzymes maintain their structural integrity and catalytic activity. Choices A, B, and D are incorrect because trypsin and chymotrypsin are not acidic enzymes, so pH ranges 1-3 and 10-12 would denature and inactivate them, while pH 5-7 is still on the acidic side, not optimal for these enzymes.
Organs that lie outside the abdominal cavity such as the duodenum, pancreas, urinary bladder and rectum are
- A. covered with parietal peritoneum.
- B. covered with visceral peritoneum.
- C. retroperitoneal.
- D. covered with serous membranes
Correct Answer: C
Rationale: The correct answer is C: retroperitoneal. Organs like the duodenum, pancreas, urinary bladder, and rectum are considered retroperitoneal because they lie behind the parietal peritoneum, which lines the abdominal cavity. They are not completely covered by visceral peritoneum (B) as they are not suspended in the abdominal cavity. They are not covered by parietal peritoneum (A) as this layer lines the abdominal wall. While these organs are covered with serous membranes (D), the defining characteristic is their location behind the peritoneum, making option C the most accurate choice.
