A nurse in an emergency department is assessing a client who is overusing prescribed diuretics and has a sodium level of 127 mEq/L. Which of the following laboratory findings should the nurse expect?

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:

While wearing a protective gown is essential to minimize exposure to bodily fluids and to ensure the nurse's protection, it is not specifically aimed at decreasing the risk for ventilator-associated pneumonia (VAP). The key interventions to prevent VAP focus on maintaining airway hygiene and proper positioning, not just personal protective equipment during suctioning.

Choice B rationale:

Monitoring oral secretions every 2 hours is an important strategy in reducing the risk of VAP. Accumulation of secretions in the mouth and upper airway can promote bacterial growth, increasing the risk of aspiration and infection. By regularly assessing and removing secretions, the nurse can reduce the chances of bacteria being aspirated into the lungs and causing pneumonia.

Choice C rationale:

Oral care every 2 hours is a critical intervention to reduce the risk of VAP. Mechanical ventilation predisposes clients to the growth of bacteria in the oral cavity, and poor oral hygiene increases the risk of oral bacteria being aspirated into the lungs. Regular oral care, including brushing teeth, gums, and the tongue, as well as using antiseptic solutions, helps reduce the microbial load in the mouth and decreases the risk of VAP.

Choice D rationale:

Maintaining a client in a supine position is not recommended for preventing VAP. The best practice is to maintain the head of the bed elevated at a 30-45 degree angle (semi-Fowler's position) to reduce the risk of aspiration. A supine position increases the likelihood of gastric contents or secretions being aspirated into the lungs, which can lead to VAP.

Choice E rationale:

Assessing the client daily for readiness for extubation is an essential practice in preventing VAP. The longer a patient remains intubated, the higher the risk of developing VAP due to prolonged exposure of the endotracheal tube in the airway. Regular assessment for extubation helps to ensure that the client is appropriately weaned off the ventilator as soon as they are stable, reducing the risk of VAP and other complications associated with prolonged ventilation.
