Correct Answer: A

Rationale: Nurses typically collect blood specimens from patients as part of their everyday duties in medical settings. They are trained in venipuncture techniques and are responsible for ensuring that blood samples are properly obtained and labeled for diagnostic testing. Medical technologists process and analyze the blood specimens in the laboratory under the direction of a physician. Physicians are not commonly involved in the direct collection of blood specimens. While phlebotomists are specialized professionals trained to draw blood, in many medical settings, nurses perform this task as part of their responsibilities.

Correct Answer: D

Rationale: The correct answer is D, Combat lifesaver. A Combat Lifesaver is a nonmedical member of a unit who receives specialized training in advanced first aid procedures, beyond basic first aid care. This training equips them to provide crucial medical assistance in emergency situations where immediate medical personnel may not be available. Choices A, B, and C are incorrect as they do not specifically refer to nonmedical members trained in advanced first aid care beyond basic procedures.

Correct Answer: B

Rationale: The Patient Holding Squad is the module that is composed of practical nurses, medical specialists, and equipment to provide medical support for minimal care patients. This squad focuses on providing necessary care for patients who require minimal attention. Choices A, C, and D are incorrect because they do not specifically cater to the needs of minimal care patients. The Treatment Squad may involve more intensive procedures, the Area Support Squad focuses on broader support functions, and the Surgical Squad is specialized for surgical interventions.

Correct Answer: B

Rationale: The correct action for the nurse to take when there is a pause after activating the machine for synchronized cardioversion on a client in atrial fibrillation is to shout "all clear" and not touch the bed. This step is crucial to ensure the safety of everyone present by warning them that the machine will discharge, preventing anyone from being inadvertently shocked. Waiting for the machine to discharge (choice A) is not recommended as it can lead to accidental injury. While ensuring the client is all right (choice C) is important, the immediate focus should be on safety during the procedure. Increasing the joules and re-discharging (choice D) without assessing the situation can pose risks to the client and the healthcare team.
