An older adult client with a history of heart failure (HF) is brought to the clinic by a family member. Which finding(s) confirm to the nurse that the client is experiencing an exacerbation of the HF? Select all that apply.

Choice A Reason:
Fluid volume excess is incorrect. Fluid volume excess refers to an overabundance of fluid in the body, leading to symptoms such as edema, weight gain, and hypertension. However, a BMI of 14 kg/m^2 indicates underweight, not fluid volume excess. Therefore, this choice is incorrect.
Choice B Reason:
Unbalanced nutrition, less than body needs is correct. A BMI of less than 18.5 indicates underweight according to the provided reference range. Underweight individuals often do not consume enough nutrients to meet their body's needs, leading to potential nutritional deficiencies. Therefore, the nursing problem of "Unbalanced nutrition, less than body needs" is appropriate for addressing the client's low BMI.
Choice C Reason:
Unbalanced nutrition, greater than body needs is incorrect. This choice would be more applicable if the client's BMI indicated overweight or obesity, as it suggests an excess intake of nutrients relative to the body's needs. However, a BMI of 14 kg/m^2 indicates underweight, not excess weight. Therefore, this choice is incorrect.
Choice D Reason:
Fluid volume deficit is incorrect. Fluid volume deficit refers to a decreased amount of fluid in the body, leading to symptoms such as dehydration, decreased urine output, and hypotension. However, a low BMI does not necessarily indicate fluid volume deficit; it primarily reflects undernutrition. Therefore, this choice is incorrect.

Choice A Reason:
Reviewing the client's serum electrolytes is incorrect. While abnormalities in electrolyte levels can sometimes contribute to neurological symptoms, such as paresthesia, reviewing the client's serum electrolytes may not directly identify additional findings consistent with the client's reported paresthesia of the hands and legs. Therefore, this option is less relevant for assessing paresthesia and identifying additional consistent findings.
Choice B Reason:
This is the correct action to identify additional findings consistent with the client's paresthesia. Paresthesia, or abnormal sensations like burning or tingling, may indicate neurological dysfunction. Assessing the client's muscle strength and hand grips can provide valuable information about neurological function and help identify any weakness or changes that may be associated with the paresthesia.
Choice C Reason:
Checking distal phalanges capillary refill is incorrect. Checking distal phalanges capillary refill is important for assessing peripheral circulation, but it may not directly identify additional findings consistent with paresthesia. While impaired circulation could contribute to sensory disturbances, such as paresthesia, it is not always the primary cause. Therefore, this option may not fully capture the sensory aspect of the client's reported symptoms.
Choice D Reason:
While observing the skin for signs of inflammation or irritation is important in assessing for other conditions, such as infection or inflammation, it is not directly related to identifying additional findings consistent with paresthesia. Paresthesia primarily involves abnormal sensations and neurological function rather than changes in the skin.
