A nurse is attending to a patient with a bowel obstruction who has been prescribed a nasogastric tube. What steps should the nurse take during the insertion of the nasogastric tube?

Remove the tube if the patient gags during insertion.

Advise the patient to tuck his chin to his chest and swallow.

Position the patient in a supine position.

Measure the tube for insertion from the nose tip to the navel.

Answer and Explanation

The Correct Answer is B

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Measuring the tube from the nose tip to the navel is an outdated practice that can lead to inaccurate placement.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 B

Explanation

Choice B rationale:

Stridor is a high-pitched, whistling sound that is heard during inspiration. It is a sign of upper airway obstruction, indicating a potentially life-threatening complication that requires immediate intervention.

Here's a detailed explanation of why stridor is the most concerning finding and why the other choices are not as indicative of a serious problem:

Stridor:

Mechanism: Stridor occurs when there is narrowing or obstruction of the upper airway, typically at the level of the larynx or trachea. This narrowing can be caused by various factors, including:

Laryngospasm: A sudden constriction of the vocal cords, often triggered by irritation or inflammation. Post-extubation edema: Swelling of the tissues in the airway after removal of the endotracheal tube.

Mucus plugging: Accumulation of thick secretions in the airway, which can partially block airflow.

Vocal cord dysfunction: Impairment of the vocal cords' movement, which can affect their ability to open and close properly.

Significance: Stridor is a serious sign because it indicates that airflow is significantly restricted. If left untreated, upper airway obstruction can lead to hypoxia (low oxygen levels) and respiratory failure.

Nursing intervention: If stridor is present, the nurse should immediately notify the provider and prepare for potential interventions to secure the airway, such as:

Reintubation: Reinserting the endotracheal tube to bypass the obstruction.

Nebulized racemic epinephrine: Medication to reduce swelling in the airway.

Heliox: A mixture of helium and oxygen that can improve airflow through a narrowed airway. Steroids: Medications to reduce inflammation in the airway.

Crackles (Choice A):

Description: Crackles are rattling, crackling sounds heard in the lungs, often during inspiration. They are typically associated with lower airway problems, such as pneumonia or pulmonary edema.

Significance: While crackles can indicate respiratory issues, they are not as immediately concerning as stridor in the context of post-extubation care.

Strong cough (Choice C):

Significance: A strong cough is generally a positive sign after extubation, as it indicates that the patient is able to clear secretions from their airway effectively.

Deep breathing (Choice D):

Significance: Deep breathing is also a positive sign, as it promotes lung expansion and oxygenation.

A. Explain the importance and rationale of implementing the new policy to the nurse. B. Encourage the nurse to verbalize the reasons for resistance to the change. C. Indicate that there will be disciplinary consequences if the nurse does not implement the new policy. D. Ignore the resistance and allow peer pressure to facilitate a change in the nurse’s behavior.

Correct Answer is B

Explanation

Choice A rationale:

While explaining the importance and rationale of the new policy may be helpful in some cases, it may not be sufficient for nurses who are resistant to change. This approach assumes that the nurse's resistance is due to a lack of understanding, which may not be the case. It's possible that the nurse understands the rationale but has other concerns or objections.

Focusing solely on explaining the rationale can make the nurse feel they are not being listened to or that their concerns are not being valued. This can further contribute to resistance.

Choice B rationale:

Encouraging the nurse to verbalize their reasons for resistance allows the nurse manager to understand the root cause of the resistance. This could include:

Concerns about the effectiveness of the new policy

Belief that the new policy will create more work or make their job more difficult

Feeling that they were not adequately consulted or involved in the decision-making process Personal factors such as fear of change or a preference for established routines

Once the nurse manager understands the nurse's concerns, they can work together to address them and find ways to facilitate acceptance of the new policy. This approach fosters open communication, collaboration, and shared decision-making, which are essential for successful change management.

Choice C rationale:

Indicating disciplinary consequences may be necessary in some cases, but it should be a last resort. It can create a negative and hostile work environment, further alienate the nurse, and potentially lead to resentment and decreased morale among other staff members.

It's important to prioritize understanding and addressing the underlying reasons for resistance before resorting to disciplinary measures.

Choice D rationale:

Ignoring the resistance and relying on peer pressure is a passive and ineffective approach. It does not address the nurse's concerns and may even exacerbate the situation. This can lead to conflict among staff members, create a divide between those who support the change and those who resist it, and potentially compromise patient care.
