A home health nurse is teaching about endotracheal suctioning. Which of the following information should the nurse include in the teaching?

Allow the client to rest for 10 to 15 seconds after each suctioning attempt.

Set the suction pressure to 110 mm Hg

Apply suction for less than 10 seconds.

Apply suction when inserting the catheter.

Answer and Explanation

Correct Answer : A,C

A) Allow the client to rest for 10 to 15 seconds after each suctioning attempt: Allowing the client to rest between suctioning attempts helps to minimize hypoxemia and reduces the risk of trauma to the airway mucosa. It also allows the client to recover from the physiological stress of suctioning before initiating another attempt.

C) Apply suction for less than 10 seconds: Prolonged suctioning can lead to hypoxemia and tissue trauma. The nurse should limit suctioning to less than 10 seconds per pass to minimize these risks and prevent complications such as mucosal damage and bleeding.

B) Set the suction pressure to 110 mm Hg: The appropriate suction pressure for endotracheal suctioning depends on various factors, including the client's age, condition, and clinical status. While suction pressures of 80 to 120 mm Hg are commonly used for adults, the specific pressure setting should be individualized based on the client's needs and should not exceed the safe range to prevent mucosal injury or hypoxemia.

D) Apply suction when inserting the catheter: Suction should be applied only during withdrawal of the catheter to minimize the risk of mucosal trauma and hypoxemia. Applying suction during catheter insertion can increase the risk of airway trauma and should be avoided.

Correct Answer is B

Explanation

A) The client reports numbness at the site: Numbness at the insertion site is not a typical finding of infection. It may indicate nerve damage or another issue but is not specific to infection.

B) Purulent drainage noted from the site: Purulent drainage, characterized by pus-like discharge, is a common sign of infection at the insertion site of an intravenous catheter. It suggests the presence of bacteria and inflammation at the site.

C) Skin over the site is sloughing: Sloughing of the skin may occur with severe tissue damage but is not specific to infection. It could indicate other complications such as tissue necrosis or chemical irritation.

D) The vein appears cord-like: A cord-like appearance of the vein, known as thrombophlebitis, can occur with or without infection. It indicates inflammation and clot formation within the vein, which can be a complication of intravenous catheter insertion, but it does not specifically indicate infection.

A. Flushed skin B. Fever C. Nausea and vomiting D. Extreme thirst

Correct Answer is C

Explanation

A) Flushed skin: Flushed skin is not typically associated with hyponatremia. Instead, hyponatremia may present with symptoms such as pallor or cool, clammy skin due to alterations in perfusion and fluid balance.

B) Fever: Fever is not a common manifestation of hyponatremia. Elevated body temperature is typically associated with conditions such as infection or inflammation rather than electrolyte imbalances like hyponatremia.

C) Nausea and vomiting: Hyponatremia, defined as a serum sodium level below 135 mEq/L, can lead to neurological symptoms, including nausea and vomiting. These symptoms occur due to alterations in osmotic pressure and cellular swelling resulting from the relative excess of water compared to sodium in the extracellular fluid. Other neurological symptoms of hyponatremia can include headache, confusion, lethargy, and seizures.

D) Extreme thirst: Extreme thirst, or polydipsia, is more commonly associated with hypernatremia, which is characterized by a serum sodium level above 145 mEq/L. Hypernatremia results from dehydration or a deficit of body water relative to sodium, leading to increased thirst as the body attempts to restore fluid balance.
