A nurse is preparing to administer vancomycin 500 mg via intermittent IV infusion every 6 hr. Available is vancomycin 500 mg in 0.9% sodium chloride 100 mL to infuse over 2 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.).

Choice A rationale:

Chronic grief is characterized by a prolonged and ongoing sense of loss that doesn't seem to improve with time. It doesn't directly relate to maladaptive coping, which the client in the scenario is exhibiting. Chronic grief may involve a persistent yearning or sadness for the deceased, but it doesn't necessarily involve maladaptive coping strategies.

Choice B rationale:

The client's use of alcohol and controlled substances to cope with the death of their partner indicates an exaggerated grief response. Exaggerated grief involves an intense and prolonged expression of grief that may be accompanied by excessive, intense emotions and behaviors. The client's use of substances to cope is an unhealthy and maladaptive way of dealing with their grief.

Choice C rationale:

Delayed grief refers to a situation where the emotional response to a loss is significantly postponed, often resulting in a delayed and intense reaction later on. It doesn't necessarily involve maladaptive coping, as seen in the client's case.

Choice D rationale:

Masked grief occurs when the grieving person's behavior and emotional responses are influenced by the loss but not recognized as being related to it. This can lead to various physical or psychological symptoms that mask the true underlying cause, the grief. While maladaptive coping can sometimes be seen in masked grief, it doesn't directly correlate with the client's substance use in this scenario.

Choice A rationale:

Performing oral care once each day is not sufficient to reduce the risk of ventilator-associated pneumonia (VAP). Ventilated patients are at an increased risk of developing VAP due to the presence of an endotracheal tube that bypasses the body's natural defenses. Bacteria can accumulate in the mouth and respiratory tract, leading to pneumonia. Therefore, performing oral care only once a day is inadequate for maintaining oral hygiene and preventing VAP.

Choice B rationale:

Brushing the client's teeth with a firm-bristle toothbrush can cause trauma to the oral tissues, potentially leading to bleeding and irritation. In critically ill patients with an endotracheal tube, using a firm-bristle toothbrush can exacerbate the risk of infection and VAP. It is essential to use gentle and non-traumatic methods for oral care to maintain the integrity of the oral mucosa.

Choice C rationale:

Swabbing the client's mouth with chlorhexidine solution is the correct choice. Chlorhexidine is an antiseptic solution that effectively reduces the growth of bacteria in the oral cavity. Regular use of chlorhexidine mouthwash has been shown to decrease the risk of VAP in mechanically ventilated patients. By reducing the bacterial load in the mouth, the risk of aspiration and subsequent pneumonia is lowered, making it a crucial intervention for preventing VAP.

Choice D rationale:

Raising the head of the bed by 15° for oral care is an important measure to prevent aspiration during oral care. However, it alone is not sufficient to reduce the risk of VAP. While proper head positioning helps prevent the entry of oral secretions into the lower respiratory tract, it must be combined with effective oral hygiene practices, such as using chlorhexidine solution, to comprehensively reduce the risk of VAP.
