A nurse is reinforcing teaching about a transcutaneous electrical nerve stimulation (TENS) unit for a client who has a herniated intervertebral disk. Which of the following statements by the client indicates an understanding of the teaching?

The nurse should perform neurovascular checks of the affected extremity every 2 hours to monitor for any signs of compartment syndrome or impaired circulation. It is important to assess for the five Ps: pain, pulse, pallor, paresthesia, and paralysis. Using a hair dryer to relieve itching can cause burns and is not a recommended intervention. Positioning the fractured arm below the level of the client's heart can increase swelling and exacerbate pain. Immobilizing the client's fingers using a hand splint is not indicated unless there is a finger fracture or injury.

Choice A (Use a hair dryer to blow hot air into the cast to relieve itching) is not an answer because it can cause burns and is not a recommended intervention.

Choice C (Position the fractured arm below the level of the client's heart) is not an answer because it can increase swelling and exacerbate pain.

Choice D (Immobilize the client's fingers using a hand splint) is not an answer because it is not indicated unless there is a finger fracture or injury.

The client should wear a mask during transport to prevent the spread of infectious droplets. The nurse should wear appropriate personal protective equipment (PPE) based on the precautions required for the specific client, which in this case would be a mask. The nurse does not need to wear a gown as droplet precautions do not require the use of a gown during transport.

The correct answer is choice C, the client should wear a mask during transport.

Choice A rationale:

The client wearing a gown during transport is not typically necessary for droplet precautions unless there is a risk of the gown becoming contaminated with infectious material. Gowns are primarily used to protect the healthcare worker or other patients if there is direct contact with the patient.

Choice B rationale:

While the nurse should wear a mask if they will be within close proximity to the client, the primary concern in droplet precautions is to prevent the spread of infection from the client, who is the source of the droplets.

Choice C rationale:

The client should wear a mask during transport to contain respiratory secretions and minimize the risk of droplet spread, as droplets can be disseminated by coughing, sneezing, or talking. This is a key component of source control in droplet precautions.

Choice D rationale:

Similar to choice A, the nurse wearing a gown during transport is not a standard requirement for droplet precautions unless there is anticipated contact with the patient or their environment that might result in contamination.

In summary, the primary goal of droplet precautions is to prevent the spread of infections through large respiratory droplets that are expelled by the client. Therefore, having the client wear a mask is the most effective measure among the options provided to reduce the risk of transmission during transport.
