A nurse is reinforcing teaching with a client who has cancer and is undergoing external radiation therapy. Which of the following instructions should the nurse include in the teaching?

A) Clenched teeth:
Clenched teeth are often a sign of discomfort or pain, especially in a client who is undergoing an epidural for pain management. This physical response typically occurs when the pain is not well controlled, as the body subconsciously tenses muscles in an attempt to cope with the pain. A clenched jaw is a clear indicator that the client is experiencing unrelieved pain, despite treatment.

B) Constipation:
Constipation is a potential side effect of medications such as opioids, which may be prescribed to manage pain. However, constipation itself is not necessarily an immediate indicator of unrelieved pain. While it can occur due to pain medications, it doesn't directly correlate with the effectiveness of pain relief from a spinal epidural.

C) Difficulty swallowing:
Difficulty swallowing, or dysphagia, is not a typical indicator of unrelieved pain. This symptom could be related to other issues such as neurological complications, side effects of medications, or other conditions. It is not a specific or common sign of ongoing pain, particularly in the context of an epidural for herniated disc treatment.

D) Urinary retention:
Urinary retention can occur due to the use of an epidural, especially if the epidural is affecting the lower spinal regions that control bladder function. However, it is more likely a side effect of the epidural itself rather than a sign that pain is unrelieved. While urinary retention should be monitored, it doesn't indicate whether the client’s pain is well-managed or not.

A) Completely undress the toddler:
Completely undressing a toddler can cause unnecessary distress and anxiety, especially if they are not prepared for the examination. It’s more appropriate to undress the toddler only as needed for the physical exam and allow them to remain clothed or partially clothed whenever possible to help them feel secure.

B) Allow the toddler to handle the equipment:
Allowing a toddler to handle the medical equipment is an excellent way to reduce fear and anxiety. This familiarizes the child with the instruments and allows them to feel more in control of the situation. It also helps in building trust with the nurse, making the examination less intimidating for the toddler.

C) Start the examination with routine immunizations:
Immunizations can be particularly stressful for toddlers, so starting the examination with vaccines is not the best approach. It’s better to begin with non-invasive procedures, such as listening to the heart or measuring the toddler’s height and weight, to build rapport before proceeding to any painful procedures.

D) Thoroughly explain each procedure to the toddler:
While it’s important to explain the examination to the toddler in simple, age-appropriate language, toddlers typically have a limited understanding of detailed explanations. Over-explaining may increase anxiety. Instead, it's better to keep things brief and comforting, using simple phrases, and focus on creating a positive experience.
