A nurse is providing care for a patient who is in skeletal traction. Which action should the nurse take?

Choice A rationale

Elevating the head of the bed 45 degrees before starting the CPM device is not necessary. The position of the bed does not affect the operation of the CPM device.

Choice B rationale

Instructing the patient to increase the degree of flexion as tolerated is not the nurse’s responsibility. The degree of flexion is usually set by the healthcare provider or physical therapist.

Choice C rationale

Ensuring the frame joint is in a flexed position before placing the leg onto the device is not necessary. The CPM device should be set up according to the manufacturer’s instructions and the healthcare provider’s orders.

Choice D rationale

Ensuring the knee joint is positioned over the CPM device frame joint is crucial. Proper alignment of the patient’s knee joint with the CPM device’s joint ensures effective and safe operation of the device.

Choice A rationale

Metoprolol is a beta-blocker that affects the heart and circulation. It does not typically cause elevated blood glucose levels.

Choice B rationale

Metoprolol is used to treat high blood pressure, not increase it. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.

Choice C rationale

Metoprolol does not typically reduce bronchospasms. In fact, it can sometimes cause breathing problems such as shortness of breath, cough, and wheezing.

Choice D rationale

Metoprolol is known to lower heart rate. This is one of the ways it helps to reduce blood pressure and relieve strains on the heart.
