A nurse is providing discharge teaching to a client who has a hearing impairment and a new hearing aid. Which of the following client statements indicates an understanding of the teaching?

A) High-pitched bowel sounds: High-pitched bowel sounds, also known as "tinkling" sounds, are characteristic of mechanical bowel obstructions. These sounds are created by the intestines as they try to move contents past the obstruction, resulting in increased peristaltic activity. In the case of intussusception, where one segment of the intestine telescopes into another, the obstruction can cause these distinctive high-pitched sounds due to the narrowing of the bowel lumen.

B) Abdominal bruit: An abdominal bruit is a swishing sound heard over the abdomen, usually indicating turbulent blood flow through narrowed arteries. It is commonly associated with vascular conditions such as atherosclerosis or renal artery stenosis. It is not related to bowel obstruction, as bowel sounds in obstruction cases are generally due to changes in peristaltic activity rather than blood flow.

C) Bruising on the flank area: Bruising on the flank area, known as Grey Turner's sign, is typically seen in conditions involving retroperitoneal hemorrhage, such as severe pancreatitis or trauma. It is not a symptom of bowel obstruction. Bowel obstruction symptoms generally relate to the gastrointestinal tract and include abdominal pain, distension, and altered bowel sounds.

D) Coffee-ground emesis: Coffee-ground emesis is vomit that appears like coffee grounds, indicating the presence of partially digested blood. This is a sign of upper gastrointestinal bleeding, often due to peptic ulcers or gastritis. In mechanical bowel obstruction, vomiting is more likely to contain bile (bilious vomiting) and may occur if the obstruction is high in the small intestine. The appearance of coffee-ground emesis is not typical for bowel obstructions and indicates a different type of gastrointestinal issue.

A) "If you experience angina, take a 10-minute rest period, then resume exercise."
It's important for clients to stop exercising immediately and consult a healthcare provider if they experience angina during exercise. Resting and then resuming exercise can be unsafe without medical advice, as angina indicates insufficient blood flow to the heart.

B) "Stop exercising if your heart rate increases by 20 beats per minute from baseline."
An increase in heart rate during exercise is expected, and stopping at a 20 BPM increase may be overly cautious. Clients should be taught to monitor for excessive fatigue or symptoms like dizziness, but a 20 BPM increase alone isn't necessarily a concern.

C) "Limit your exercise to an indoor facility to avoid exposure to the sun."
While excessive sun exposure can be a concern for some individuals, limiting exercise to indoors is unnecessary unless there are specific contraindications. Clients should be encouraged to exercise in environments they enjoy, with appropriate sun protection if outdoors.

D) "Begin by walking half a mile two times a day for the first week."
This recommendation is a reasonable starting point for postoperative exercise. Walking is a low-impact exercise that can help improve cardiovascular health gradually. Clients should gradually increase their activity level based on their tolerance and healthcare provider's advice.
