Correct Answer: A

Rationale: When a person is struck by lightning, it can cause an electrical shock that may affect the heart rhythm. Therefore, assessing pulse characteristics is crucial as lightning can act as a natural defibrillator. Monitoring the pulse rate and regularity will help determine if there are any cardiac abnormalities that need immediate attention. Open airway, entrance and exit wounds, and cervical spine injury assessments are also important but assessing pulse characteristics takes precedence in this situation to address potential cardiac issues.

Correct Answer: A

Rationale: The ventrogluteal site is the preferred location for administering large volume IM injections to avoid nerve injury. This site is situated away from major nerves and blood vessels, reducing the risk of complications associated with injecting into other areas. The ventrogluteal site allows for deep muscle penetration and is recommended for injections over 2 mL in volume to ensure proper dispersion and absorption of the medication. Choices B, C, and D are incorrect because the outer upper quadrant of the buttock is not the recommended site for large volume injections, two inches below the acromion process is a location for a deltoid injection, and the vastus lateralis is typically used for smaller volume injections.

Correct Answer: A

Rationale: Using sterile technique when applying the compresses is crucial to prevent infection and promote wound healing. Ensuring a clean environment during wound care reduces the risk of introducing pathogens that can lead to complications. Proper infection control measures play a significant role in the healing process of open wounds. Choice B is incorrect because leaving the compresses on continuously can lead to skin damage or thermal injury. Choice C is incorrect as alternating warm compresses with cold compresses is not appropriate for an open wound. Choice D is incorrect as applying a wet dressing without following specific orders can be detrimental to wound healing.

Correct Answer: D

Rationale: Before assisting the client out of bed, the nurse should first assess the client's blood pressure and pulse. This assessment is crucial to determine the client's physiological stability and readiness for ambulation. It ensures the client's safety during the transfer and helps prevent any potential complications that may arise from getting out of bed. Administering oxygen, lying the client back down, or quickly moving the client to a chair without assessing vital signs can compromise the client's safety and may lead to adverse outcomes.

Correct Answer: B

Rationale: Hinge joints, like the elbow, primarily allow movement in one direction, in this case, bending the arm. The correct action to exercise hinge joints is to bend the arm by flexing the ulnar to the humerus. This movement specifically targets the hinge joint and promotes its range of motion. Choices A, C, and D involve movements that do not specifically target hinge joints. Tilt the pelvis involves the ball-and-socket joints of the hip, turning the head involves the pivot joint of the neck, and extending the arm and rotating it in circles involve multiple joints including ball-and-socket and pivot joints.
