A nurse is reinforcing teaching with a client about preventing the transmission of hepatitis A. The nurse should identify that hepatitis A is transmitted by which of the following routes?

Choice A reason: Having the client gently blow clots from his nose every 5 min is an incorrect action, because it can increase the bleeding and trauma to the nasal mucosa. The client should avoid blowing or picking his nose.

Choice B reason: Instructing the client to sit with his head hyperextended is an incorrect action, because it can cause the blood to drain into the throat and increase the risk of aspiration or vomiting. The client should sit with his head tilted forward.

Choice C reason: Applying ice compresses to the back of the client’s neck is an incorrect action, because it has no effect on the bleeding site. The nurse should apply ice compresses to the bridge of the nose or the cheeks to constrict the blood vessels and reduce the bleeding.

Choice D reason: Pinching the soft portion of the client’s nose for 10 min is a correct action, because it applies direct pressure to the bleeding site and allows clot formation. The nurse should instruct the client to breathe through his mouth and avoid swallowing the blood.

Choice A reason: This is a correct statement, because checking the heart rate each day can help monitor the function and effectiveness of the pacemaker, and detect any signs of malfunction, such as bradycardia, tachycardia, or irregular rhythm.

Choice B reason: This is an incorrect statement, because the client still needs to take the antihypertensive medications as prescribed, even with a pacemaker. The pacemaker regulates the heart rate, but does not control the blood pressure, which can be affected by other factors, such as stress, diet, or kidney function.

Choice C reason: This is an incorrect statement, because the client should avoid stretching the arms above the head for the first few weeks after the pacemaker insertion, as it can cause dislodgment or damage to the pacemaker leads. The client should limit the arm movements and activities until the incision site heals and the provider approves.

Choice D reason: This is an incorrect statement, because the client can stand in front of a microwave oven without any risk, as long as the oven is in good working condition and does not leak radiation. The modern microwave ovens and pacemakers are designed to prevent any interference or damage. However, the client should avoid close contact with other sources of electromagnetic fields, such as metal detectors, cell phones, or MRI machines.
