A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory tests should the nurse review prior to adjusting the client's heparin?

- 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.

Droplet.

The rationale for each choice is as follows:

• A. Droplet: Correct. Pneumonia is transmitted by respiratory droplets that are generated by coughing, sneezing, or talking. The nurse should wear a surgical mask and eye protection when caring for the client and maintain a distance of at least 3 feet from the client.
• B. Airborne: Incorrect. Airborne precautions are used for diseases that are transmitted by small particles that remain suspended in the air for long periods of time, such as tuberculosis, measles, or chickenpox. The nurse should wear a respirator and place the client in a negative-pressure room.
• C. Contact: Incorrect. Contact precautions are used for diseases that are transmitted by direct or indirect contact with the client or the client's environment, such as Clostridium difficile, scabies, or MRSA. The nurse should wear gloves and a gown and use dedicated equipment for the client.
• D. Protective environment: Incorrect. Protective environment precautions are used for clients who are immunocompromised and at risk of infection from others, such as clients who have had a stem cell transplant or are receiving chemotherapy. The nurse should wear a mask, gloves, and a gown and place the client in a positive-pressure room with HEPA filtration.
