A nurse is assisting a provider with a client who is to undergo a thoracentesis.
In which of the following positions should the nurse place the client?
Supine with the head of the bed flat.
Trendelenburg with the head flexed.
Sitting upright while leaning forward over pillows.
Lying prone with arms extended away from body.
The Correct Answer is C
Choice A rationale
The supine position with the head of the bed flat does not facilitate the safe and effective draining of fluid from the pleural cavity. This position can compromise the respiratory status of the patient and is therefore not suitable for a thoracentesis.
Choice B rationale
The Trendelenburg position, where the head is lower than the feet, can increase intracranial pressure and is not suitable for thoracentesis. This position does not allow for the optimal access to the pleural space needed for the procedure.
Choice C rationale
Sitting upright while leaning forward over pillows is the ideal position for a thoracentesis. This position allows the fluid to accumulate at the base of the pleural cavity and provides easy access for the procedure. It also facilitates better breathing and reduces the risk of injury to the diaphragm and other internal structures.
Choice D rationale
Lying prone with arms extended away from the body does not provide adequate access to the pleural space for thoracentesis. This position also makes it difficult to manage and monitor the patient's respiratory status during the procedure. .

Correct Answer is A
Explanation
Choice A rationale
Losing excess weight can help reduce the risk of stroke by lowering blood pressure and improving overall cardiovascular health.
Choice B rationale
An HbA1c level of 6 percent or less is typically considered good control of diabetes and does not increase the risk of stroke.
Choice C rationale
A total cholesterol level below 200 mg/dL is actually desirable and helps reduce the risk of stroke.
Choice D rationale
Glucocorticoids are not typically prescribed to reduce the risk of stroke; they can increase blood sugar levels and other risk factors. .
Correct Answer is A
Explanation
Choice A rationale
Platelets 60,000/mm³ is significantly below the normal range of 150,000 to 400,000/mm³, which can indicate a risk of bleeding and is a concern for a procedure like a liver biopsy.
Choice B rationale
Ammonia levels of 55 mcg/dL are within the normal range of 10 to 80 mcg/dL, so this value does not need to be reported.
Choice C rationale
Bilirubin 1.0 mg/dL is at the upper limit of the normal range of 0.3 to 1.0 mg/dL, but it does not necessarily indicate a significant risk for a liver biopsy.
Choice D rationale
Aspartate aminotransferase 34 units/L is at the upper limit of the normal range of 0 to 34 units/L, but it does not indicate a contraindication for the biopsy.
