A nurse is collecting data from a client following the application of a leg cast for the treatment of a fracture. Which of the following findings should the nurse expect to find first if the cast is too tight?

Toes cool to touch

Inability to move toes

Pallor of the toes

Edema of the toes

Answer and Explanation

The Correct Answer is A

The correct answer is choice A: Toes cool to touch.

Choice A rationale: When a cast is too tight, it can compromise blood circulation to the extremity. This results in decreased blood flow and reduced oxygenation, causing the toes to feel cool to the touch.

Choice B rationale: Inability to move toes is a significant concern that can also indicate nerve compression due to a tight cast. However, it may not be the first sign of a tight cast, as impaired blood circulation will likely be evident before nerve damage.

Choice C rationale: Pallor of the toes, or a pale appearance, can occur when there is restricted blood flow. However, the coolness of the toes is often noticeable before pallor develops.

Choice D rationale: Edema of the toes, or swelling, can occur due to a tight cast, but it is usually a later sign. Initially, the toes may feel cool to the touch, followed by other symptoms such as pallor, pain, and eventually, swelling.

Correct Answer is D

Explanation

The nurse should immediately report small drops of clear ﬂuid in the left ear to the charge nurse. This finding could indicate a cerebrospinal ﬂuid (CSF) leak, which can occur as a result of a head injury. A CSF leak can be a serious medical condition that requires immediate attention.

An edematous bruise on the forehead, client disorientation to place, and a heart rate of 110/min and regular are also important findings that the nurse should report to the charge nurse. However, these findings are not as urgent as the presence of small drops of clear ﬂuid in the left ear.

A. Taking too much prescribed medication B. Developing a respiratory infection C. Insufficient sleep D. Insufficient exercise

Correct Answer is B

Explanation

The nurse should identify that developing a respiratory infection can cause a myasthenic crisis in a client who has myasthenia gravis. A myasthenic crisis is a sudden worsening of myasthenia gravis symptoms, which can include difficulty breathing and swallowing. Respiratory infections can exacerbate these symptoms and trigger a myasthenic crisis.

Taking too much-prescribed medication, insufficient exercise, and insufficient sleep are not factors that can cause a myasthenic crisis. Taking too much-prescribed medication can cause side eﬀects but would not directly cause a myasthenic crisis. Insufficient exercise and insufficient sleep can worsen overall health but would not directly cause a myasthenic crisis.
