The nurse is reviewing the laboratory findings of a patient to assess the patient's nutritional status.
The nurse understands the laboratory finding that is the best indicator of inadequate protein intake is a:
High blood urea nitrogen.
Low specific gravity.
Low serum albumin.
High hemoglobin.
The Correct Answer is C
Choice A rationale
High blood urea nitrogen (BUN) levels primarily indicate impaired kidney function or dehydration, as urea is a waste product of protein metabolism filtered by the kidneys. While severe protein catabolism can elevate BUN, it is not the most direct or sensitive indicator of inadequate protein intake. Normal BUN ranges typically fall between 7 to 20 mg/dL.
Choice B rationale
Low specific gravity of urine suggests that the kidneys are excreting dilute urine, which can be caused by various factors such as excessive fluid intake, diabetes insipidus, or kidney dysfunction. It is not a reliable indicator of protein nutritional status. Normal urine specific gravity ranges from 1.005 to 1.030.
Choice C rationale
Serum albumin is a protein synthesized by the liver and is a key indicator of long-term protein status. Inadequate protein intake leads to decreased albumin synthesis, resulting in low serum albumin levels. Albumin has a relatively long half-life (around 20 days), making it a reflection of chronic protein deficiency. Normal serum albumin levels typically range from 3.5 to 5.0 g/dL.
Choice D rationale
Hemoglobin is the protein in red blood cells responsible for oxygen transport. While severe protein deficiency can eventually affect hemoglobin levels due to the protein component, it is not the most direct or immediate indicator of inadequate protein intake. Other factors like iron deficiency are more commonly associated with low hemoglobin. Normal hemoglobin ranges for adults are typically 13.5 to 17.5 g/dL for males and 12.0 to 15.5 g/dL for females.

Correct Answer is C
Explanation
Choice A rationale
Asking "How loud is his snoring?" is subjective and difficult for the spouse to quantify accurately. While loudness can be a factor, it doesn't directly address potential underlying medical conditions like obstructive sleep apnea.
Choice B rationale
Determining the frequency of awakenings due to snoring provides some information about the impact on the spouse's sleep but doesn't offer specific details about the nature of the snoring itself or potential pauses in breathing.
Choice C rationale
Asking "Is there silence after snoring which then is followed with a snort?" directly inquires about a pattern indicative of obstructive sleep apnea. Apneic episodes involve cessation of breathing (silence), followed by a gasp or snort as the airway reopens.
Choice D rationale
Knowing the duration of snoring each night provides a general overview but doesn't offer specific details about the characteristics of the snoring, such as pauses in breathing or gasping, which are crucial for identifying potential sleep disorders. .
Correct Answer is D
Explanation
Choice A rationale
Expressing remorse indicates an awareness of the negative consequences of past actions, which aligns with the valuing process step of choosing, where the individual recognizes the value and impact of different choices. However, it doesn't fully demonstrate prizing, which involves cherishing and affirming the value.
Choice B rationale
Explaining how past choices contributed to the renal failure demonstrates understanding and cognitive processing of the situation, aligning with the choosing step of the valuing process, where the individual intellectually recognizes the value. However, it doesn't necessarily indicate an emotional investment or affirmation of new values.
Choice C rationale
Stating an intention to adopt new behaviors reflects the acting step of the valuing process, where the individual commits to and implements the chosen values in their actions. While important for change, it doesn't directly demonstrate the internal valuing or cherishing of these new actions.
Choice D rationale
Expressing pride in gaining knowledge and skills to manage diabetes signifies that the client now holds this self-management in high regard and finds personal worth in it. This aligns with the prizing step of the valuing process, where the individual emotionally embraces and values the new belief or behavior, leading to a sense of satisfaction and affirmation.
