Prior to an invasive examination of a hospitalized client, a consent form should be obtained. Which action best describes the responsibility of the practical nurse (PN)?

The correct answer is choice A: Never scratch under the cast.

Choice A rationale:

It is important not to scratch under the cast because inserting objects can lead to skin injury and infection. If itching occurs, blowing cool air from a hair dryer into the cast is recommended.

Choice B rationale:

While mild swelling and some discomfort are common after a cast is applied, patients should not expect an increase in pain. Persistent or severe pain could indicate complications such as increased swelling, decreased blood flow, or pressure on nerves and should be evaluated by a healthcare provider.

Choice C rationale:

Applying a cold pack to “hot spots” on the cast is not recommended as it can lead to moisture accumulation and skin problems. Instead, to manage swelling and discomfort, ice can be applied over the cast, covered with a thin towel, for 20 minutes every two hours while awake during the first 48 hours.

Choice D rationale:

Keeping the injured leg in a dependent position is not advised because it can increase swelling and pain. The affected limb should be elevated above the level of the heart to reduce swelling and promote healing.

Correct Answer: D. Report the findings to the charge nurse.

Choice A rationale:

Monitoring the client's temperature hourly may be indicated if the client's condition deteriorates or if there are specific concerns about fever. However, the temperature of 99.8°F (37.66°C) is not significantly elevated and may not be the primary concern in this situation.

Choice B rationale:

Offering the client fluids frequently is a good nursing practice, but it is not the most important intervention in this case. The client's nonproductive cough and increased confusion need to be addressed and reported first.

Choice C rationale:

Providing care to moisten oral mucosa is important for maintaining oral health and preventing dryness and discomfort. However, it may not directly address the client's current symptoms of cough and confusion.

Choice D rationale:

Reporting the findings to the charge nurse is the most crucial intervention. The client's nonproductive cough and increased confusion may be indicative of an underlying issue, such as a respiratory infection or a change in neurological status. The charge nurse can initiate further assessments, notify the healthcare provider, and implement appropriate interventions to address the client's condition promptly. Timely reporting and communication are essential to ensure the client receives appropriate care.
