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: The presentation of a palpable, non-tender mass in the right neck, just below the angle of the mandible, along with ultrasound imaging findings of a well-defined, hypoechoic lesion with cystic components, is classic for a branchial cleft cyst. Branchial cleft cysts are congenital anomalies that arise from remnants of the branchial clefts or pouches during embryonic development. They are typically located along the anterior border of the sternocleidomastoid muscle, just below the mandible. Ultrasound imaging often shows a cystic lesion with well-defined borders and hypoechoic content, which is consistent with the described findings. Thyroglossal duct cysts usually present as midline neck masses that move with swallowing or tongue protrusion, not in the location described in the scenario. Lymphadenopathy would present as enlarged lymph nodes that may be tender and associated with systemic symptoms.

Correct Answer: D

Rationale: Negligence refers to the failure to take proper care in doing something. In this scenario, the nurse failed to exercise the standard of care expected in placing a heating pad directly on Mr. C's lower leg, knowing his history of peripheral vascular disease. This failure led to a burn and subsequent infection that required a skin graft for treatment. The actions of the nurse were negligent as they did not meet the expected standard of care, resulting in harm to the patient. This situation does not fit the definition of assault, malpractice, or vicarious liability, making negligence the most appropriate choice.

Correct Answer: B

Rationale: The nurse's appropriate response is to provide the requested information clearly and directly. In this case, the client asked for the time, so the best response is to say "It is 10 o'clock" to answer their question promptly. Options A, C, and D do not address the client's question and may be perceived as dismissive or unhelpful.

Correct Answer: B

Rationale: Long-term aspirin therapy, especially at higher doses, can increase the risk of gastrointestinal bleeding. Aspirin irreversibly inhibits cyclooxygenase enzyme, which is essential for the production of prostaglandins involved in mucosal protection of the gastrointestinal tract. Without these protective prostaglandins, the stomach lining becomes more susceptible to damage from gastric acid, leading to potential ulcer formation and bleeding. Patients with a history of coronary artery disease may be on aspirin for secondary prevention, and it is crucial to monitor for signs of bleeding such as black, tarry stools or abdominal pain. The benefits of aspirin in preventing cardiovascular events need to be weighed against the risk of adverse effects like gastrointestinal bleeding, especially in patients on long-term therapy.
