A nurse is reviewing the ABGs of a client who has pneumonia. The nurse should identify which of the following findings is an indication of respiratory acidosis.

Choice A rationale:
Allergy to eggs is not a contraindication for taking chondroitin with glucosamine. These supplements do not contain eggs and are generally safe for individuals with egg allergies.
Choice B rationale:
Hypotension is not directly related to the use of chondroitin with glucosamine. These supplements are not known to cause significant changes in blood pressure.
Choice C rationale:
History of hypoglycemia is not a specific concern with chondroitin and glucosamine supplements. These supplements do not significantly impact blood sugar levels in people without diabetes.
Choice D rationale:
The correct choice. The nurse should instruct the client to use chondroitin with glucosamine with caution if they are on anticoagulant therapy. Chondroitin and glucosamine may have mild anticoagulant effects, and when combined with prescribed anticoagulant medications, there is a potential risk of increased bleeding or altered blood clotting times. It is essential to monitor the client's coagulation parameters closely if they decide to use these supplements.

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.
