The practical nurse (PN) observes that a client is experiencing melena. Which serum laboratory test should the PN monitor in response to this finding?

Rationale:

A. In what part of town is your home located: This question assesses environmental or social context but does not provide information about the client’s level of physical activity or mobility. Disuse syndrome is related to prolonged immobility and inactivity, so location alone does not help evaluate risk or presence of muscle atrophy, contractures, or deconditioning.

B. On a scale 0-10, how would you rate overall pain level: Pain assessment is important in neuromuscular conditions because it can limit mobility. However, pain alone does not directly assess the extent of activity or immobility contributing to disuse syndrome. Additional functional questions are needed to determine how inactivity is affecting the client’s musculoskeletal system.

C. What is included in a typical day for you: This question directly evaluates the client’s level of daily activity, mobility, and engagement in physical tasks. Disuse syndrome develops from prolonged inactivity leading to muscle atrophy, decreased strength, and joint stiffness. Understanding daily routines provides insight into whether the client is at risk due to insufficient movement.

D. Do you feel you are financially stable: Financial stability relates to socioeconomic status and access to care but does not directly assess physical activity or immobility. While it may influence overall health outcomes, it does not provide specific information about the development of disuse syndrome.

E. How much assistance do you need to move around: This question assesses the client’s level of dependence in mobility and ability to perform transfers or ambulation. Increased reliance on assistance suggests reduced muscle use, which contributes to muscle wasting, decreased endurance, and joint contractures characteristic of disuse syndrome.

Rationale:

A. Obtain a pulse oximeter reading: Pulse oximetry measures oxygen saturation and does not provide information regarding lymph node abnormalities. It is unrelated to the assessment of neck lymphadenopathy and would not guide follow-up care for an enlarged node.

B. Assess for tenderness or pain: Evaluating tenderness, consistency, mobility, and size of the lymph node helps differentiate between reactive lymphadenopathy due to infection and more concerning causes such as malignancy. Tender, soft, and mobile nodes indicate an inflammatory process, whereas hard, fixed, and nontender nodes may suggest a more serious pathology.

C. Ask about the onset of syncope: Syncope is related to cardiovascular or neurological issues and does not provide information about lymph node enlargement. It is not a relevant follow-up assessment in this context.

D. Check for the presence of a thrill: A thrill is a palpable vibration over an artery or vascular anomaly and is unrelated to lymph node assessment. This action would not yield clinically useful information for an enlarged cervical lymph node.
