DHA Critical Care Nurse - General Exam Info Sample Questions

Most calcium channel blockers work by blocking calcium ion channels in the plasma membranes of what?





Correct Answer:
smooth muscle.


calcium channel blockers are a class of medications that primarily target the smooth muscles in the walls of arteries. these drugs function by inhibiting the influx of calcium ions through specific channels in the plasma membranes of smooth muscle cells.

calcium ions play a critical role in the contraction mechanisms of muscle cells, including smooth muscles, which are found in the walls of arteries and arterioles. by blocking calcium channels, these medications prevent calcium from entering the cells, thus reducing muscular contraction. this relaxation of the vascular smooth muscle leads to a dilation of the blood vessels, which in turn lowers blood pressure and reduces the strain on the heart.

the impact of calcium channel blockers is more pronounced on arterial smooth muscle compared to venous smooth muscle. this selective action is beneficial in treating conditions like hypertension (high blood pressure) and angina (chest pain caused by reduced blood flow to the heart muscle), as these conditions primarily involve the arteries rather than the veins.

while calcium channel blockers are effective in targeting vascular smooth muscle, they have lesser effects on other types of muscle tissues, such as striated muscle, which includes skeletal and cardiac muscle. similarly, these drugs do not significantly affect nerve tissue or epithelial tissue, both of which have different mechanisms and roles in the body.

understanding the specific action of calcium channel blockers on vascular smooth muscle helps in their appropriate application in clinical settings, ensuring that they are used effectively to manage specific cardiovascular conditions.

What does a tension pneumothorax require?





Correct Answer:
chest tube


tension pneumothorax is a serious and potentially life-threatening condition that occurs when air enters the pleural space, the area between the lungs and the chest wall, and continues to accumulate without an escape route. this build-up of air puts increasing pressure on the lung, eventually causing it to collapse. it can also shift the mediastinum (the central compartment of the thoracic cavity) to the opposite side, which can compress the heart and major blood vessels, decreasing cardiac output and leading to life-threatening consequences.

the primary treatment required for a tension pneumothorax is the immediate decompression of the pleural space. this is typically achieved by the insertion of a chest tube, a procedure known as tube thoracostomy. the chest tube allows the trapped air to escape, thereby relieving the pressure on the lung and other thoracic structures. this procedure helps re-expand the collapsed lung and restore normal cardiopulmonary function.

in emergency situations, where a chest tube cannot be immediately placed, a needle decompression may be performed. this involves the insertion of a needle into the pleural space to provide a temporary relief by allowing air to escape until a chest tube can be inserted. however, needle decompression is only a temporary measure, and placement of a chest tube remains essential for definitive management.

aside from mechanical intervention, supplemental oxygen is often provided to improve oxygenation, especially if the patient is hypoxic. it is important, however, to understand that while oxygen can help alleviate symptoms associated with low blood oxygen levels, it does not address the root cause of the tension pneumothorax, which is the physical compression due to the trapped air.

in conclusion, the management of a tension pneumothorax primarily requires the insertion of a chest tube to drain the air from the pleural space, thereby relieving pressure, allowing lung re-expansion, and stabilizing the patient. prompt medical intervention is crucial to prevent severe complications or death.
