A patient undergoing mechanical ventilation in the ICU develops ventilator-associated pneumonia (VAP) caused by multidrug-resistant organisms (MDROs). What intervention should the healthcare team prioritize to manage the patient's infection?

Correct Answer: A

Rationale: The most appropriate intervention for managing ventilator-associated pneumonia (VAP) caused by multidrug-resistant organisms (MDROs) is to administer combination antibiotic therapy targeting the specific resistant pathogens identified in the patient's culture results. MDROs are often resistant to multiple antibiotics, so combination therapy is required to maximize the chances of effectively treating the infection. Identifying the specific pathogens causing the VAP through cultures is crucial in tailoring the antibiotic therapy to target these organisms effectively. Implementing appropriate antibiotic therapy promptly is essential to improve outcomes and prevent further complications in patients with VAP caused by MDROs. Option A is the priority intervention in this case to address the multidrug-resistant nature of the infection and provide targeted treatment for the patient.

Correct Answer: B

Rationale: Phlebitis is the most common complication that patients may contract while on IV therapy. Phlebitis is the inflammation of the vein where the IV is inserted, which can cause redness, pain, and swelling along the vein. It can be caused by mechanical irritation, chemical irritation, or infection from the IV catheter. Prompt removal of the IV catheter and appropriate treatment are necessary to manage phlebitis and prevent further complications. While embolism, cardiac overload, and aneurysm are potential complications of IV therapy, phlebitis is more commonly seen in clinical practice.

Correct Answer: B

Rationale: The 5's strategy to prevent dengue infection includes Search and Destroy mosquito breeding places, seek early consultation at the nearest health care facility, say no to fogging spraying, and misting in hot spot areas. While using mosquito repellent on exposed skin is a common preventive measure against mosquito bites, applying it all over your body is not included in the official 5's strategy for dengue prevention. The focus of the 5's strategy is on eliminating mosquito breeding sites, seeking medical advice early in case of symptoms, and avoiding certain mosquito control methods like fogging in hot spot areas.

Correct Answer: A

Rationale: Patients with COPD are at increased risk for developing ventilator-induced lung injury (VILI) due to their underlying lung pathology. Using a low tidal volume strategy (6-8 ml/kg predicted body weight) has been shown to reduce the risk of VILI in these patients. Additionally, applying high positive end-expiratory pressure (PEEP) helps to recruit collapsed alveoli, improve oxygenation, and decrease the risk of barotrauma by keeping the alveoli open throughout the respiratory cycle. Therefore, the most appropriate ventilator settings to minimize the risk of VILI in a COPD patient with acute exacerbation and respiratory failure requiring mechanical ventilation would be low tidal volume and high PEEP.

Correct Answer: A

Rationale: An open chest wound, also known as a sucking chest wound, can lead to a collapsed lung and respiratory distress. Immediate management involves sealing the wound to prevent air from entering the pleural space and further compromising the patient's respiratory function. Applying a sterile dressing over the wound helps to prevent contamination and occluding the wound with an airtight covering, such as an occlusive dressing, can effectively reduce the risk of a tension pneumothorax, a serious complication that can arise from a sucking chest wound. These interventions help to stabilize the patient's condition and improve the chances of a successful recovery. Administering supplemental oxygen, though beneficial, would be secondary to the primary management of sealing the chest wound. Providing emotional support is important but addressing the physical emergency takes precedence. Elevating the patient's legs would not be appropriate in managing an open chest wound.

Correct Answer: C

Rationale: In cases of persistent fetal malpresentation, such as a transverse lie position, a cesarean section is often the safest and most effective intervention to address the abnormal labor presentation. Delivering a baby in a transverse lie position vaginally is associated with high risks, including fetal complications such as umbilical cord prolapse and head entrapment. Therefore, to ensure the safety of both the mother and the baby, a cesarean section is usually the most appropriate and timely intervention to address this situation. It is crucial to prioritize the immediate preparation and facilitation of a cesarean section in cases of persistent fetal malpresentation to prevent potential complications and ensure the best outcome for the mother and the baby.

Correct Answer: C

Rationale: Hyperthyroidism is a condition where the thyroid gland produces an excess amount of thyroid hormone. One of the clinical manifestations of hyperthyroidism is a fine motor tremor, which is characterized by hand tremors or shaky movements in the fingers. This tremor is often more noticeable when the individual is trying to perform delicate tasks requiring fine motor skills. It is important for Nurse Rachel to watch for this symptom in patient Claire as it can impact her ability to perform daily activities and may require intervention or management strategies to help alleviate the tremor and improve quality of life.

Correct Answer: B

Rationale: The correct information about the nature of dengue fever that the nurse should relay to the community is that it could be deadly but preventable. Dengue fever is a viral infection spread by mosquitoes, particularly the Aedes aegypti mosquito. While many cases of dengue fever are mild, it can also lead to severe dengue, which can be life-threatening if not properly managed. However, preventive measures such as using mosquito repellent, wearing protective clothing, and eliminating breeding sites for mosquitoes can significantly reduce the risk of contracting dengue fever. Therefore, it is important for the community to be aware that while dengue fever can be deadly, it is also preventable with appropriate measures.

Correct Answer: C

Rationale: Mast cells are primarily responsible for mediating allergic responses such as severe allergies. When an allergen triggers the immune response, mast cells release histamine, leukotrienes, and other inflammatory mediators. These substances cause symptoms such as difficulty breathing, hives, and swelling. Basophils also release histamine, but mast cells are more abundant in tissues and play a significant role in allergic reactions. Eosinophils are involved in allergic reactions but are more focused on combating parasitic infections. Neutrophils are not typically involved in allergic responses but play a key role in combating bacterial infections.
