A nurse is assisting an older adult client who sometimes loses her balance while walking. Which of the following devices should the nurse use when helping the client ambulate?

A. This refers to irregular bleeding between menstrual periods. While anorexia nervosa can lead to amenorrhea (the absence of menstruation) due to hormonal imbalances from severe weight loss and malnutrition, metrorrhagia is not a typical finding associated with anorexia nervosa.
B. This is a condition characterized by elevated levels of potassium in the blood. It is not a common finding in anorexia nervosa. Instead, clients with anorexia nervosa are more likely to have electrolyte imbalances such as hypokalemia (low potassium levels), especially if they engage in behaviors like vomiting or excessive use of laxatives.
C. This is a common finding in clients with anorexia nervosa. Constipation occurs due to inadequate intake of food and fluids, which results in decreased bowel motility. Malnutrition and dehydration from restricted intake can also contribute to this problem.
D. This refers to an abnormally fast heart rate. While tachycardia can occur in various conditions, in the context of anorexia nervosa, clients may actually exhibit bradycardia (slow heart rate) rather than tachycardia. The low body weight and malnutrition associated with anorexia can lead to a slowed heart rate as part of the body's response to starvation and decreased metabolic activity.

A. A urine output of 175 mL over 8 hours is significantly below normal, which is generally considered less than 0.5 mL/kg/hr in adults (the normal range is about 0.5-1.5 mL/kg/hr). Reduced urine output can be indicative of acute kidney injury or worsening renal function, and it needs prompt evaluation and intervention.
B. This finding is generally not urgent but could be noted. Strong-smelling urine, especially in the morning, may be due to concentration of waste products overnight or dietary factors. While it might suggest dehydration or infection, it is less immediately concerning than changes in urine output. If accompanied by other symptoms such as pain, fever, or changes in urine color, it might warrant further investigation.
C. This finding is typically within normal limits and may not need immediate reporting. Normal urine output is about 800-2,000 mL per day. An output of 2,200 mL is slightly elevated but still within the normal range, depending on fluid intake.
D. This finding is generally not urgent but worth noting. Cloudy urine can result from the presence of cells, bacteria, or other substances. It may become cloudy after standing due to the formation of crystals or precipitation of substances.
