A patient with osteoarthritis is scheduled for a total knee arthroplasty. The nurse identifies that the surgery will be postponed if the patient experiences which condition?

Chronic joint inflammation

Pain

Infection

Immobility

Answer and Explanation

The Correct Answer is C

A. Chronic joint inflammation is a common feature of osteoarthritis, but it does not necessarily preclude surgery. In fact, joint inflammation is often a reason for considering a total knee arthroplasty.
B. Pain is a typical symptom of osteoarthritis, but it is not a reason to postpone surgery. Pain management can be addressed during the perioperative period.
C. Infection is a critical factor that would delay surgery. If the patient has an active infection, particularly in the joint or surrounding tissues, the risk of spreading the infection during surgery is high, and the procedure would need to be postponed until the infection is resolved.
D. Immobility is a concern for postoperative recovery but does not typically delay surgery. Physical therapy and rehabilitation can address immobility after the procedure.

Correct Answer is D

Explanation

A. Sodium bicarbonate is typically used in cases of metabolic acidosis, especially during prolonged resuscitation efforts. It is not the first-line medication for symptomatic bradycardia.
B. Magnesium is used in cases of torsades de pointes or other arrhythmias associated with low magnesium levels. It is not indicated for symptomatic bradycardia.
C. Epinephrine is used in cases of cardiac arrest to stimulate the heart and improve perfusion, but it is not the first-line treatment for symptomatic bradycardia.
D. Atropine is the first-line medication for symptomatic bradycardia. It works by blocking the parasympathetic effects on the heart, increasing heart rate. This is especially useful in bradycardia that is causing symptoms like hypotension or altered mental status.

A. Notify the dietary department of the client's allergy. B. Ask the client if any other foods cause such a reaction. C. Attach a wrist band indicating the client's allergy. D. Notify the provider of the client's allergy

Correct Answer is D

Explanation

A. While notifying the dietary department of the client's allergy to shellfish is important, the priority is to ensure that the healthcare provider is aware of the allergy, especially since shellfish allergies are often associated with iodine-based contrast agents used in cardiac catheterization.
B. Asking about other foods causing a reaction is helpful for understanding the scope of the client's allergies, but it is not the priority in this situation. The primary concern is the shellfish allergy, which may relate to contrast dye.
C. While it is important to attach an allergy wristband, the most critical action is to notify the provider so that alternative contrast agents can be considered if necessary.
D. Notifying the provider of the client's shellfish allergy is the priority action. Shellfish allergies can indicate a potential reaction to iodine-based contrast media, which could lead to severe reactions such as anaphylaxis. The provider needs to be aware to take appropriate precautions.
