A home health nurse is caring for a group of older adult clients. The nurse should initiate a referral to the Program of All-Inclusive Care for the Elderly (PACE) for which of the following clients?

- A. This choice is incorrect because an older adult client who reports constipation of 4 days is not an urgent situation that requires immediate attention. The nurse should assess the client's hydration status, bowel habits, and medication use, and provide education on dietary and lifestyle modifications to prevent constipation.

- B. This choice is incorrect because a preschooler who has a skin rash is not an urgent situation that requires immediate attention. The nurse should assess the type, location, and distribution of the rash, as well as any history of allergies, exposure, or infection, and provide appropriate treatment and education.

- C. This choice is incorrect because an adolescent who has a closed fracture is not an urgent situation that requires immediate attention. The nurse should assess the site of injury, neurovascular status, pain level, and immobilization device, and provide analgesia and education on fracture care.

- D. This choice is correct because a middle adult client who has unstable vital signs is an urgent situation that requires immediate attention. The nurse should assess the client's level of consciousness, airway, breathing, circulation, and possible causes of instability, and initiate lifesaving interventions.

- A. Incorrect. The lithotomy position is not appropriate for this procedure, as it can cause discomfort and embarrassment to the client. The nurse should place the client in a left lateral Sims' position with the right knee flexed for better access to the rectum and to reduce pressure on the abdominal organs.

- B. Incorrect. The nurse should avoid eliciting a vagal response, as it can cause bradycardia, hypotension, and syncope in some clients. The nurse should monitor the client's vital signs and stop the procedure if signs of vagal stimulation occur.

- C. Incorrect. Oral bisacodyl is a stimulant laxative that can cause abdominal cramping, diarrhea, and electrolyte imbalance. It is not indicated for fecal impaction, as it can worsen the condition by increasing the bulk and hardness of the stool. The nurse should administer an enema or a stool softener before attempting digital evacuation.

- D. Correct. The nurse should insert a lubricated gloved finger and advance along the rectal wall, breaking up the stool and removing it in small pieces. The nurse should use gentle pressure and avoid injuring the rectal mucosa. The nurse should also explain the procedure to the client and obtain informed consent before performing it.
