The nurse is the first person on the scene of a motor vehicle crash. The victim was the driver and is in the driver's seat unconscious. The driver is breathing, has a pulse, and has minor lacerations on the head and face. What action should the nurse implement first?

Use the head tilt chin lift method to maintain the airway

Control any external bleeding

Do not move the victim from the accident

Stabilize the cervical spine until help arrives

Answer and Explanation

The Correct Answer is D

A. The head tilt chin lift method should be avoided due to the risk of aggravating a spinal injury; the jaw-thrust maneuver is safer if airway management is necessary.

B. While controlling bleeding is important, cervical spine stabilization takes priority in trauma with suspected spinal injury.

C. Not moving the victim is appropriate, but stabilizing the cervical spine provides active support to avoid further injury.

D. Stabilizing the cervical spine is crucial to prevent potential spinal cord damage in an unconscious trauma victim, particularly in a motor vehicle accident. This action helps prevent exacerbation of any spinal injury.

Correct Answer is A

Explanation

A. Metoprolol, a beta-blocker, decreases the heart rate and reduces myocardial oxygen demand by lowering the workload on the heart, which is beneficial for managing unstable angina.

B. While metoprolol has some vasodilatory effects, its primary action is to reduce heart workload, not to dilate coronary arteries.

C. Although beta-blockers can reduce the risk of arrhythmias, the main purpose in angina management is to decrease cardiac workload.

D. Metoprolol does not make the heart beat more forcefully; instead, it decreases the force of contraction to reduce myocardial oxygen consumption.

A. Fifth intercostal space, left midclavicular line B. Fourth intercostal space, right sternal boarder C. Third intercostal space, left midclavicular line D. Second intercostal space, right sternal boarder

Correct Answer is A

Explanation

A. The fifth intercostal space at the left midclavicular line is the location of the mitral valve, where murmurs associated with mitral valve disease are best auscultated.

B. The fourth intercostal space at the right sternal border is the location for assessing the tricuspid valve, not the mitral valve.

C. The third intercostal space at the left midclavicular line is not associated with loudest auscultation of the mitral valve murmur.

D. The second intercostal space at the right sternal border is where the aortic valve sounds are best heard.
