A nurse is caring for a client who has diabetes mellitus and is receiving long-acting daily insulin for blood glucose management.
The nurse should anticipate administering which of the following types of insulin?

Choice A rationale:

The described cardiac rhythm with a wavy baseline, no distinguishable P waves, and an increased heart rate is consistent with atrial fibrillation. In atrial fibrillation, the atria quiver instead of contracting effectively, leading to an irregular and often rapid heart rate. This rhythm is characterized by the absence of distinct P waves on the ECG.

Choice B rationale:

Ventricular asystole is a flatline on the ECG, indicating the absence of electrical activity in the heart. It is a life-threatening arrhythmia and requires immediate intervention with cardiopulmonary resuscitation (CPR) and advanced cardiac life support (ACLS) protocols.

Choice C rationale:

Second-degree heart block is characterized by intermittent failure of atrial electrical impulses to conduct to the ventricles. This results in occasional dropped beats and a varying heart rate. It is not consistent with the described ECG findings in the question.

Choice D rationale:

Sinus tachycardia is a regular, fast heart rate originating from the sinoatrial (SA) node. In sinus tachycardia, P waves are present, indicating that the electrical impulses originate in the SA node. The described ECG findings do not match the characteristics of sinus tachycardia.

Choice A rationale:

Documenting the desire to be an organ donor in writing is a legal requirement and ensures that the individual's wishes are respected after their passing. It also provides clear guidance to healthcare providers and family members about the individual's decision.

Choice B rationale:

There is no specific age requirement to become an organ donor. People of various ages can register as organ donors, and eligibility often depends on the condition of the organs at the time of death.

Choice C rationale:

Once someone is listed as an organ donor, their name can be removed if they change their mind. It's essential for individuals to inform their family members about their decision and ensure their wishes are respected.

Choice D rationale:

The nurse can indeed be a witness for the consent to donate. Being a witness ensures the authenticity of the individual's decision to become an organ donor and can be helpful in legal and ethical contexts.
