Foundations and Adult Health Nursing Study Guide Answers

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: A

Rationale: Hemoperfusion is not a standard management technique for poisoning. The other options are commonly used methods in managing poisoning cases.

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: D

Rationale: The symptoms described - muscle weakness, fatigue, constipation, hyperpigmentation of the skin, low serum cortisol levels, and elevated ACTH levels - are classic findings in Addison's disease. Addison's disease is a primary adrenal insufficiency characterized by the insufficient production of cortisol and, to some extent, aldosterone. The low cortisol levels result in symptoms such as muscle weakness, fatigue, and skin hyperpigmentation due to increased levels of ACTH stimulating melanin production. In contrast, in conditions like hyperthyroidism, hypothyroidism, and diabetes mellitus, the symptoms and laboratory findings would not fully align with those described in the patient in this scenario.

Correct Answer: A

Rationale: Osteoporosis is a common complication associated with long-term use of corticosteroids in orthopedic patients. Corticosteroids can lead to bone loss by inhibiting bone formation and promoting bone resorption, resulting in decreased bone mineral density and increased risk of fractures. Therefore, patients on long-term corticosteroid therapy, especially in high doses, should be monitored closely for osteoporosis and receive appropriate preventive measures such as calcium, vitamin D supplementation, and bisphosphonates to mitigate the risk of bone thinning and fractures.
