A client with syndrome of inappropriate antidiuretic hormone secretion (SIADH) is admitted with hyponatremia. Which intervention is most important for the nurse to include in the plan of care to protect the client from injury?

Heart failure in older adults involves the heart’s inability to maintain cardiac output, leading to pulmonary and systemic venous congestion. When the left ventricle fails, fluid backs up into the lungs, causing interstitial edema and crackles. This shift in fluid dynamics results in impaired gas exchange and orthopnea, necessitating immediate repositioning and pharmacological intervention to reduce preload and improve respiratory efficiency.

Rationale:

A. Administering the prescribed furosemide is a vital pharmacological intervention to treat the underlying fluid overload. As a loop diuretic, it inhibits sodium reabsorption, causing rapid diuresis that reduces circulatory volume and pulmonary congestion. This action directly addresses the cause of the crackles and pedal edema by shifting fluid out of the tissues.

B. Raising the head of the bed to the Fowler’s position is the initial priority to alleviate orthopnea. This position allows the abdominal contents to move downward, reducing pressure on the diaphragmatic muscle and increasing thoracic capacity. By optimizing lung expansion, the nurse provides immediate, non-invasive relief to the patient’s respiratory distress before other interventions.

C. Providing oxygen per nasal cannula addresses the hypoxemia indicated by the saturation of 93%. Supplemental oxygen increases the concentration of oxygen in the alveoli, facilitating better diffusion across the fluid-filled membranes of the lungs. Correcting the oxygen deficit is a critical secondary step to prevent myocardial strain and cellular hypoxia in the elderly client.

D. Monitoring urinary output is the final step used to evaluate the effectiveness of the diuretic therapy. The nurse must track the volume and concentration of urine to ensure the kidneys are responding to the medication and that fluid balance is being restored. This assessment provides the objective data needed to guide further treatment and ensure patient safety.

Type 1 diabetes mellitus involves the autoimmune destruction of pancreatic beta cells, resulting in absolute insulin deficiency and a lifelong requirement for exogenous hormone replacement. A new diagnosis often triggers the stages of grief, specifically anger or denial, as the client confronts a significant lifestyle alteration and the burden of chronic self-management. Effective patient education cannot occur when a client is in a state of emotional distress, as psychological barriers significantly impair the cognitive processing of complex clinical information.

Rationale:

A. Explaining that insulin is life-saving during an outburst of anger is often perceived as condescending or threatening, further escalating the client's frustration. While medically factual, the client is currently emotionally unavailable to process rational justifications for treatment. The nurse must prioritize the therapeutic relationship over immediate factual instruction to ensure long-term compliance.

B. Referring a client to a social worker immediately after a single episode of anger is an excessive intervention that may be interpreted as a dismissal of the client's feelings. Anger is a normal adjustment response to a life-altering diagnosis and does not necessarily indicate a need for professional therapy. Initial support should come from the primary nursing staff through empathy and patience.

C. Encouraging relaxation techniques while a client is actively shouting is ineffective and dismissive of their current emotional state. Forcing a coping strategy during a peak emotional crisis typically increases resistance to learning and damages rapport. The client requires personal space and time to regain autonomy before they can engage in any therapeutic or behavioral interventions.

D. Leaving the room is the most appropriate action because it respects the client's current boundaries and allows the anger to subside. Returning later in the day demonstrates professional persistence and provides a new opportunity for teaching when the client is more stable. Timing is a critical component of readiness to learn, which must be assessed before proceeding with insulin education.
