The practical nurse (PN) administers an injection using a syringe with a retractable needle. After the needle is removed from the client's skin, the needle does not retract, and the PN gets stuck in the finger with the used needle. What action should the PN take first?

The correct answer is choice A: Have the client sit down in the hall.

Choice A rationale: The PN should first have the client sit down to help alleviate the client's chest tightness and shortness of breath. Sitting down allows for better lung expansion and reduces the risk of falling due to dizziness or lightheadedness. This is the most appropriate initial action in response to the client's complaint.

Choice B rationale: While assisting the client back to their room is important, the PN should first ensure that the client is sitting down to help manage their symptoms. After the client is seated and more stable, the PN can then assist them back to their room for further assessment and intervention.

Choice C rationale: Administering sublingual nitroglycerin may be appropriate if the client is experiencing cardiac-related chest pain. However, the PN should first have the client sit down and gather more information about their symptoms before administering any medications.

Choice D rationale: Obtaining a 12-lead electrocardiogram can help assess the client's cardiac status, but it is not the first action that the PN should take in this situation. Ensuring the client's safety and managing their symptoms are immediate priorities. The PN can consider obtaining an electrocardiogram after addressing the client's immediate needs and assessing their condition further.

A thready pulse is a weak and rapid pulse that is easily obliterated by light pressure. It indicates poor blood flow and perfusion and may be caused by conditions such as shock, dehydration, or hemorrhage.

The other options are not correct because:

B. A missing pulse is a pulse that is absent or cannot be detected, even with firm pressure. It indicates a complete blockage of blood flow, and may be caused by conditions such as arterial occlusion, embolism, or trauma.

C. Light pressure applied to pulse is not a documentation of the pulse quality, but a description of the technique used to palpate the pulse.

D. Pulse skips beats is a documentation of an irregular pulse rhythm, not a pulse volume. It indicates that the heart beats are unevenly spaced, and may be caused by conditions such as arrhythmia, stress, or caffeine intake.
