A nurse is providing postoperative care for a patient who has a closed-wound drainage system. Which of the following actions should the nurse perform?
Irrigate the tubing with sterile normal saline solution at least once every 8 hours.
Replace the drainage plug after releasing hand pressure on the device.
Fully recollapse the reservoir after emptying it.
Empty the reservoir once per day.
The Correct Answer is C
Choice A rationale:
Irrigating the tubing with sterile normal saline solution is not a routine part of closed-wound drainage system care.
It's usually only done if there's evidence of a blockage or infection, and only under the direction of a healthcare provider. Unnecessary irrigation could introduce bacteria into the system and increase the risk of infection.
It could also disrupt the delicate balance of fluids in the wound and delay healing.
Choice B rationale:
Replacing the drainage plug after releasing hand pressure on the device is not correct. The drainage plug should actually be replaced before releasing hand pressure.
This is to prevent air from entering the system, which could disrupt the vacuum and impair drainage.
Choice D rationale:
Emptying the reservoir once per day is not frequent enough.
The reservoir should be emptied whenever it becomes full, which could be more often than once a day, depending on the amount of drainage.
Allowing the reservoir to become too full could put pressure on the wound and impede healing.
Choice C rationale:
Fully re-collapsing the reservoir after emptying it is essential to maintain the vacuum that promotes drainage. If the reservoir is not fully re-collapsed, the vacuum will be lost, and drainage will slow or stop.
This could lead to fluid accumulation in the wound, which could increase the risk of infection and delay healing.

Correct Answer is B
Explanation
Choice A rationale:
Removing the tube immediately upon patient gagging is not the most appropriate first step. Gagging is a common reflex during nasogastric tube insertion and can often be managed without removing the tube.
Premature removal could lead to unnecessary discomfort for the patient and potential delays in treatment.
The nurse should attempt to reposition the tube or have the patient sip water to facilitate passage before considering removal.
Choice B rationale:
Tucking the chin to the chest and swallowing are essential maneuvers that help guide the tube into the esophagus and reduce the risk of misplacement into the trachea.
These actions close off the airway and open the esophagus, creating a smoother path for the tube.
The nurse should instruct the patient to perform these actions during insertion to promote successful placement.
Choice C rationale:
While a supine position is often used for nasogastric tube insertion, it is not the most crucial factor for success.
Studies have shown that a high-Fowler's position (sitting upright with head elevated) may be equally effective and potentially more comfortable for patients.
The nurse should consider patient comfort and potential contraindications (such as respiratory distress) when choosing the most appropriate position.
Choice D rationale:
Measuring the tube from the nose tip to the navel is an outdated practice that can lead to inaccurate placement. The correct measurement is from the nose tip to the earlobe to the xiphoid process (NEX).
This landmark-based method provides a more reliable estimation of the distance to the stomach.
Correct Answer is D
Explanation
Choice A rationale:
Distended neck veins are not a reliable indicator of dehydration in adults. They can be caused by other factors, such as heart failure or fluid overload.
In cases of dehydration, the veins in the neck may actually be less visible due to decreased blood volume.
It's important to assess for other signs and symptoms of dehydration, such as urine output, skin turgor, and vital signs, to make an accurate diagnosis.
Choice B rationale:
A bounding pulse can be a sign of dehydration, but it can also be caused by other factors, such as anxiety, exercise, or fever. It's important to assess the pulse rate and rhythm in conjunction with other signs and symptoms to determine the cause.
A normal pulse rate is 60-100 beats per minute in adults. A bounding pulse is typically a strong, forceful pulse that can be easily felt.
Choice C rationale:
A blood pressure of 146/94 mm Hg is considered elevated, but it is not necessarily a sign of dehydration. Blood pressure can be elevated due to other factors, such as stress, pain, or underlying medical conditions. It's important to assess blood pressure in conjunction with other signs and symptoms to determine the cause. Choice D rationale:
Urine specific gravity is a measure of the concentration of solutes in the urine. A higher urine specific gravity indicates more concentrated urine, which is a sign of dehydration.
A normal urine specific gravity is 1.005-1.030. A urine specific gravity of 1.034 is considered high and is a strong indicator of dehydration.
