A nurse is completing discharge teaching with a client who has a new prescription for enoxaparin to treat unstable angina. Which of the following instructions should the nurse include in the teaching?

Choice A rationale:
The nurse should instruct the client to place cellular phones on the ear opposite the side of the pacemaker to minimize the risk of electromagnetic interference. Although the risk of interference is low with modern pacemakers, it is still a precautionary measure. Placing the phone on the ear opposite the pacemaker reduces the likelihood of any potential electromagnetic interaction.
Choice B rationale:
The instruction in choice B, "Avoid showering for the first 2 weeks following surgery,”. is not appropriate. There is no need for the client to avoid showering after pacemaker insertion. In fact, maintaining good hygiene is essential to prevent infection at the incision site. The client can take a shower, but they should avoid soaking the incision area and patting it dry afterward.
Choice C rationale:
The instruction in choice C, "Avoid heavy lifting for 1 week following insertion,”. is not the best option. The recommended timeframe to avoid heavy lifting after a pacemaker insertion is usually around 4 to 6 weeks. This duration allows the surgical site to heal properly and reduces the risk of dislodging the pacemaker leads or causing damage.
Choice D rationale:
The instruction in choice D, "Stand at least 2 feet away while using a microwave,”. is not directly related to pacemaker care. While it is generally recommended to maintain a safe distance from microwaves during use, this instruction is not specific to clients with pacemakers.

Choice A rationale:
Expiratory rhonchi are typically associated with conditions such as chronic bronchitis or asthma but are not specific to pulmonary embolism.
Choice B rationale:
Petechiae over the lower extremities is not a characteristic finding in pulmonary embolism. Petechiae are tiny red or purple spots that appear due to bleeding under the skin and may be associated with other conditions like thrombocytopenia.
Choice C rationale:

The correct choice. Hemoptysis, which refers to coughing up blood, is a concerning finding in pulmonary embolism. It occurs due to the obstruction of blood flow in the pulmonary vasculature, leading to blood leaking into the lungs.
Choice D rationale:
Flattened neck veins are more likely to be observed in conditions associated with decreased venous return to the heart, such as hypovolemia or cardiac tamponade, and are not directly related to pulmonary embolism.
