A patient presents with chest pain, dyspnea, and signs of hypotension. An electrocardiogram (ECG) shows ST- segment elevation in the inferior leads. Which cardiovascular disorder is most likely responsible for these symptoms?

Correct Answer: C

Rationale: Chest pain, dyspnea, hypotension, and ST-segment elevation on an ECG in the inferior leads are classic signs of an acute myocardial infarction (MI). An acute MI occurs when there is a sudden blockage of blood flow to a part of the heart muscle, leading to tissue damage. This causes symptoms such as chest pain due to ischemia, dyspnea due to heart failure, and hypotension due to poor cardiac output. The ST-segment elevation seen on the ECG is indicative of significant myocardial injury. Prompt diagnosis and management are crucial in acute MI to prevent further complications and to minimize damage to the heart muscle. It is important to differentiate an acute MI from stable or unstable angina or other cardiovascular disorders, as the management and prognosis vary significantly.

Correct Answer: A

Rationale: The clinical presentation of fever, chills, headache, and myalgia after a trip to sub-Saharan Africa is highly indicative of malaria. Specifically, the presence of intraerythrocytic ring forms and trophozoites on blood smear examination points towards Plasmodium falciparum as the most likely causative agent. Plasmodium falciparum is the most deadly of the Plasmodium species that cause malaria and is responsible for the majority of severe malaria cases worldwide. It is transmitted through the bite of infected Anopheles mosquitoes. Treatment for Plasmodium falciparum infection usually involves antimalarial medications such as artemisinin-based combination therapies.

Correct Answer: D

Rationale: Ovarian torsion is the most likely cause of the pregnant woman's symptoms as described. Ovarian torsion occurs when the ovary twists on its pedicle, leading to compromised blood flow to the ovary. This can cause severe abdominal pain, bloating, and constipation. On examination, an abdominal mass may be palpable due to an enlarged, twisted ovary. Bowel sounds may be diminished due to the effect of the torsion on surrounding structures. Ectopic pregnancy, threatened abortion, and placenta previa are less likely to present with an abdominal mass and diminished bowel sounds.

Correct Answer: A

Rationale: Checking the flow of oxygen is the priority action because it ensures that Sonny is receiving the correct amount of oxygen prescribed by the healthcare provider. Before connecting the flow meter to the oxygen outlet, turning on the oxygen, or attaching the humidifier, it is crucial to verify that the flow rate is appropriate for Sonny's condition. Monitoring and adjusting the oxygen flow will help maintain the desired oxygen saturation levels and prevent potential complications related to oxygen therapy.

Correct Answer: B

Rationale: Risk management in a healthcare facility involves identifying, assessing, and minimizing risks to prevent potential harm to patients and reduce liability issues. A planned program of loss prevention and liability control falls under the umbrella of risk management. This program includes strategies to mitigate risks such as patient safety protocols, infection control measures, staff training, and proper documentation practices to minimize legal liabilities. By implementing risk management practices, healthcare facilities aim to provide safe and high-quality care to their patients while also protecting themselves against potential legal challenges.

Correct Answer: A

Rationale: The right to considerate and respectful care irrespective of socio-economic status is applicable in this case because Mr. Steve is facing financial difficulties in paying for his medical bills. This right ensures that all patients receive proper treatment and care regardless of their ability to pay. It emphasizes that every individual deserves to be treated with dignity and respect, regardless of their financial situation. In Mr. Steve's case, being referred to a social worker due to inability to pay should not impact the quality of care and respect he receives from healthcare providers.

Correct Answer: C

Rationale: Allowing people's participation to confirm the health problems would yield better results in facilitating the recognition of the community's health issues. By involving the community members themselves in the process of identifying and acknowledging their health problems, there is a higher likelihood of garnering accurate and relevant information. This participatory approach fosters a sense of ownership and empowerment among the community members, making them more likely to actively engage in addressing the identified health concerns. Additionally, community participation can help build trust between the nurse and the residents, leading to more effective communication and collaboration in improving overall health outcomes.

Correct Answer: B

Rationale: Vestibular neuritis is a condition characterized by the acute onset of severe vertigo, nausea, vomiting, and nystagmus. These symptoms are typically worsened by head movement. Vestibular neuritis is caused by inflammation of the vestibular nerve, which plays a key role in balance and spatial orientation. The classic presentation of these symptoms, along with the absence of hearing loss (which is seen in labyrinthitis), points towards vestibular neuritis as the most likely cause in this scenario. Meniere's disease presents with recurrent episodes of vertigo, hearing loss, tinnitus, and sensation of fullness in the ear. Benign paroxysmal positional vertigo (BPPV) is characterized by brief episodes of vertigo triggered by changes in head position.

Correct Answer: C

Rationale: The most commonly associated adverse effect with ACE inhibitors is a dry cough. This cough is non-productive and can be quite bothersome for patients, often leading to non-compliance with the medication. The cough is thought to be due to the accumulation of bradykinin and substance P, which are vasodilatory and bronchoconstrictive peptides that are normally degraded by ACE. When ACE is inhibited, these peptides accumulate and can lead to irritation of the respiratory tract, resulting in the dry cough. It's important for healthcare providers to be aware of this common side effect and consider alternative medications if the cough becomes problematic for the patient.
