A nurse is caring for a client who is receiving mechanical ventilation. Which of the following actions should the nurse implement to decrease the client's risk for ventilator-associated pneumonia (VAP)? (Select all that apply.).

Wear a protective gown when suctioning the client's airway.

Monitor for oral secretions every 2 hr.

Provide oral care every 2 hr.

Maintain the client in a supine position.

Assess the client daily for readiness of extubation.

Answer and Explanation

Correct Answer : B,C,E

Choice A rationale:

While wearing a protective gown is essential to minimize exposure to bodily fluids and to ensure the nurse's protection, it is not specifically aimed at decreasing the risk for ventilator-associated pneumonia (VAP). The key interventions to prevent VAP focus on maintaining airway hygiene and proper positioning, not just personal protective equipment during suctioning.

Choice B rationale:

Monitoring oral secretions every 2 hours is an important strategy in reducing the risk of VAP. Accumulation of secretions in the mouth and upper airway can promote bacterial growth, increasing the risk of aspiration and infection. By regularly assessing and removing secretions, the nurse can reduce the chances of bacteria being aspirated into the lungs and causing pneumonia.

Choice C rationale:

Oral care every 2 hours is a critical intervention to reduce the risk of VAP. Mechanical ventilation predisposes clients to the growth of bacteria in the oral cavity, and poor oral hygiene increases the risk of oral bacteria being aspirated into the lungs. Regular oral care, including brushing teeth, gums, and the tongue, as well as using antiseptic solutions, helps reduce the microbial load in the mouth and decreases the risk of VAP.

Choice D rationale:

Maintaining a client in a supine position is not recommended for preventing VAP. The best practice is to maintain the head of the bed elevated at a 30-45 degree angle (semi-Fowler's position) to reduce the risk of aspiration. A supine position increases the likelihood of gastric contents or secretions being aspirated into the lungs, which can lead to VAP.

Choice E rationale:

Assessing the client daily for readiness for extubation is an essential practice in preventing VAP. The longer a patient remains intubated, the higher the risk of developing VAP due to prolonged exposure of the endotracheal tube in the airway. Regular assessment for extubation helps to ensure that the client is appropriately weaned off the ventilator as soon as they are stable, reducing the risk of VAP and other complications associated with prolonged ventilation.

Correct Answer is A

Explanation

Choice A rationale:

The nurse should wash the client in a distal to proximal direction during a bed bath after a cerebrovascular accident (CVA) to prevent the risk of clot dislodgement. This method ensures that any potential clots or debris are moved away from the central circulation, reducing the risk of harm.

Choice B rationale:

Using a circular motion with the washcloth can increase friction and potentially irritate the skin. Clients with a history of CVA might have reduced sensation or mobility, making them susceptible to skin breakdown. Hence, avoiding circular motions is important to prevent skin damage.

Choice C rationale:

Massaging the legs after completing the bath can also pose a risk of clot dislodgement. It is essential to avoid vigorous massage on areas affected by deep vein thrombosis (DVT) to prevent complications like pulmonary embolism.

Choice D rationale:

There is no need to disconnect the IV tubing before performing the bath unless specifically indicated by the healthcare provider. In general, clients receiving continuous IV infusions can continue the infusion while maintaining proper infection control measures during the bath.

A. PaO2 86 mm Hg. B. pH 7.4. C. HCO3 16 mEq/L. D. PaCO2 58 mm Hg.

Correct Answer is D

Explanation

Choice A rationale:
A PaO2 value of 86 mm Hg is within the normal range (80-100 mm Hg) and does not indicate respiratory acidosis. PaO2 measures the partial pressure of oxygen in arterial blood.
Choice B rationale:
A pH of 7.4 is within the normal range (7.35-7.45) and does not indicate respiratory acidosis. The pH reflects the acidity or alkalinity of the blood.
Choice C rationale:
An HCO3 (bicarbonate) level of 16 mEq/L is within the normal range (22-28 mEq/L) and does not indicate respiratory acidosis. HCO3 is a measure of the metabolic component of the body's acid-base balance.
Choice D rationale:
This is the correct choice. A PaCO2 value of 58 mm Hg is elevated and indicates respiratory acidosis. PaCO2 measures the partial pressure of carbon dioxide in arterial blood, and an elevated value suggests the presence of excess carbon dioxide, leading to acidosis.
