A nurse is caring for a client who reports taking 0.5 oz of diphenhydramine elixir every night to sleep. The concentration on the client's bottle reads diphenhydramine 12.5 mg/5 mL. How many mg of diphenhydramine is the client taking each night? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Indication of potential improvement:
• Shortness of breath with exertion
• Lung sounds clear

Indication of potential worsening condition:
• WBC count 11,800/mm³
• Temperature 38.5°C (101.3°F)
• Weight 113 kg (249 lb)
• Creatinine 1.8 mg/dL

Rationale:

• Shortness of breath with exertion: Previously, the client had dyspnea at rest. Improvement to exertional dyspnea suggests better fluid balance and cardiac function.

• Lung sounds clear: The initial presence of crackles indicated pulmonary congestion. Clear lung sounds suggest reduced fluid overload, reflecting improved cardiac function.

• WBC count 11,800/mm³: An increasing WBC count suggests a possible infection, which can worsen heart failure by increasing metabolic demands and fluid retention.

• Temperature 38.5°C (101.3°F): Fever indicates a possible infection, such as a UTI, which the client has a history of. Infections can exacerbate heart failure by triggering systemic inflammation and fluid shifts.

• Weight 113 kg (249 lb): Weight gain in heart failure is often due to fluid retention, indicating worsening congestion.

• Creatinine 1.8 mg/dL: A rising creatinine level suggests worsening kidney function, which may result from reduced perfusion due to heart failure or excessive diuresis from furosemide.

A. Applying a vest restraint daily at bedtime is inappropriate because restraints should only be used as a last resort when other interventions have failed. Restraints must be ordered based on ongoing assessment rather than routine use, as they pose risks such as impaired circulation, skin breakdown, and decreased mobility.

B. Soft heel protectors help prevent pressure injuries and provide cushioning for clients at risk of skin breakdown. They are a non-restrictive intervention and do not require verification with the provider.

C. An abduction pillow helps maintain proper hip alignment and prevents dislocation in clients following hip surgery. This is a standard postoperative intervention that does not require additional verification.

D. Mitten restraints are a less restrictive alternative to wrist restraints and may be used to prevent a client from interfering with medical devices. However, their use still requires a provider's order and close monitoring to ensure patient safety.
