A nurse is caring for a client who is obese and is prescribed a calorie reduction of 500 fewer calories per day. The nurse should expect the client to have which of the following rates of weight loss?

0.45 kg (1 lb)/week

0.45 kg (1 lb)/day

0.23 kg (0.5 lb)/week

0.23 kg (0.5 lb)/day

Answer and Explanation

The Correct Answer is A

The nurse should expect the client to have a weight loss rate of 0.45 kg (1 lb) per week when reducing their calorie intake by 500 calories per day. A general guideline for weight loss is that a calorie deficit of 500 calories per day can lead to a weight loss of approximately 0.45 kg (1 lb) per week. This estimate is based on the notion that 1 pound of body weight is roughly equivalent to 3,500 calories. By creating a calorie deficit of 500 calories per day (500 calories x 7 days = 3,500 calories), the client can expect to lose around 0.45 kg (1 lb) of weight per week.

It is important to note that individual factors, such as metabolism and activity level, can influence weight loss rates. Therefore, the actual rate of weight loss may vary among individuals. It is generally recommended to aim for gradual and sustainable weight loss rather than rapid or extreme weight loss.

Correct Answer is B

Explanation

Coronary heart disease (CHD) is a condition characterized by the buildup of plaque in the coronary arteries, leading to reduced blood flow to the heart. Several risk factors contribute to the development of CHD, including high blood glucose levels, high levels of low-density lipoprotein (LDL) cholesterol, and high total cholesterol levels.

HbA1c 5%: HbA1c is a measure of average blood glucose levels over the past 2-3 months. A level of 5% is within the target range for individuals without diabetes and indicates good glycemic control. It does not place the client at risk for CHD.

Fasting glucose 140 mg/dL: Fasting glucose levels above 126 mg/dL are considered diagnostic criteria for diabetes mellitus. A level of 140 mg/dL indicates hyperglycemia and suggests impaired glucose metabolism, which is a risk factor for CHD.

LDL 64 mg/dL: LDL cholesterol is often referred to as "bad" cholesterol, as elevated levels are associated with an increased risk of CHD. A level of 64 mg/dL is within the desirable range and does not place the client at risk for CHD.

Total cholesterol 173 mg/dL: Total cholesterol levels below 200 mg/dL are generally considered desirable. A level of 173 mg/dL is within the desirable range and does not place the client at risk for CHD.

A. BUN 15 mg/dL B. Blood pressure 150/82 mm Hg C. Urine specific gravity 1.010 D. Urine output of 20 mL/hr

Correct Answer is D

Explanation

A urine output of 20 mL/hr is considered to be low and suggests decreased fluid intake or fluid loss. In a postoperative client with an indwelling urinary catheter, a low urine output may indicate dehydration, especially if the client is not receiving adequate fluids or experiencing excessive fluid loss.

BUN 15 mg/dL: Blood urea nitrogen (BUN) is a laboratory value that reflects the amount of urea nitrogen in the blood and can be used to assess kidney function and hydration status. A BUN level of 15 mg/dL falls within the normal range, indicating that the client's kidneys are adequately removing urea from the blood. However, it does not provide definitive information about hydration status on its own.

Blood pressure 150/82 mm Hg: The blood pressure reading of 150/82 mm Hg does not provide specific information about hydration status. It is important to consider the client's baseline blood pressure, medical history, and other factors when interpreting blood pressure readings.

Urine specific gravity 1.010: A urine specific gravity of 1.010 falls within the normal range and does not indicate dehydration. It suggests that the concentration of solutes in the urine is within the expected range.
