Choice A rationale:

"I'll get you some over-the-counter pain relievers." Over-the-counter pain relievers may not be sufficient to manage severe abdominal pain associated with PID.

Prescription analgesics are often required for adequate pain control, making this option less appropriate.

Choice B rationale:

"Let's apply a cold pack to your lower abdomen." Applying a cold pack may provide some relief for mild discomfort but is not suitable for managing severe abdominal pain associated with PID.

It is essential to address the pain adequately with medication rather than relying solely on non-pharmacological interventions.

Choice C rationale:

"I'll administer the prescribed analgesics as ordered." This is the most appropriate nursing intervention for managing severe abdominal pain in a client with PID.

Administering prescribed analgesics as ordered by the healthcare provider ensures effective pain relief and is in line with the standard of care for managing PID-related pain.

Choice D rationale:

"You should try some deep breathing exercises to relieve the pain." Deep breathing exercises can be helpful for relaxation and pain management in some situations, but they may not be sufficient for managing severe abdominal pain associated with PID.

Pharmacological interventions are typically necessary to provide adequate pain relief.

Therefore, this option is less appropriate for managing the client's pain in this context.
