Question 1
ECG shows ST-segment elevation in leads II, III, and aVF. Most likely diagnosis?
Correct Answer:
Acute inferior myocardial infarction (STEMI)
Explanation:
ST-segment elevation in the inferior leads (II, III, and aVF) localizes the problem to the inferior wall of the heart. When the ECG shows this pattern, it points to an acute inferior myocardial infarction caused by a sudden occlusion of a coronary artery, most often the right coronary artery. This is a STEMI, meaning the injury is transmural and requires urgent reperfusion. In contrast, an acute anterior MI would produce ST elevations in the chest leads (V1–V4), not the inferior leads. Non-ST-elevation MI would not have ST elevation, instead showing ST depression or T-wave changes. Aortic dissection isn’t diagnosed from this pattern and would present differently with symptoms and diagnostic clues beyond the ECG.
Question 2
Which is a protective factor for suicide risk?
Correct Answer:
Strong social support
Explanation:
Strong social support acts as a protective factor against suicide by providing emotional connection, practical help, and encouragement to seek help during times of distress. When someone has reliable relationships—family, friends, mentors, or community networks—they’re less likely to feel isolated, more likely to cope with painful thoughts, and more likely to access mental health resources in a crises moment. This connectedness helps regulate stress, reduces impulsivity in crises, and creates a safety net that can promote help-seeking behavior. In contrast, easier access to lethal means increases risk because it makes a lethal option more readily available during a crisis. A history of prior attempts is a known risk factor, signaling a higher probability of future attempts. Substance abuse can worsen mood, impair judgment, and amplify risk during depressive or crisis states.
Question 3
Which of the following should be used to relieve RSV nasal symptoms in children?
Correct Answer:
Saline drops
Explanation:
Saline drops are the best choice because they address the mucosal congestion directly and safely. RSV causes inflammation and increased mucus in the nasal passages, leading to swelling and blockage. Icing in on that swelling with plain saline helps loosen and thin the mucus, moisturize the nasal lining, and make it easier to clear secretions—often improving breathing, feeding, and sleep. It’s a simple, nonpharmacologic option that is appropriate for children. Antibiotics don’t help with a viral infection like RSV, since there’s no bacteria to target, and using them unnecessarily can cause side effects and contribute to resistance. Corticosteroids and antihistamines aren’t routinely beneficial for nasal symptoms due to RSV in kids and can have limited effectiveness or unwanted effects. If needed, saline is used regularly to provide relief, sometimes followed by gentle suction to remove loosened mucus.
Question 4
Which factors can increase the need for vitamin C?
Correct Answer:
Stress, illness, and cigarette smoking
Explanation:
Increased vitamin C needs come from situations that raise oxidative stress or demand more collagen and immune activity. Stress, illness, and cigarette smoking all push the body to use and lose vitamin C more quickly. Smoking introduces a lot of free radicals, so the antioxidant vitamin C is used up to neutralize them, leading to lower levels unless intake is increased. Illness and inflammation boost the immune response and tissue repair processes, which require vitamin C for producing collagen and supporting white blood cell function; this elevates daily needs. Physical or emotional stress also raises metabolic activity and may increase antioxidant use, including vitamin C. Regular exercise with adequate sleep is not inherently a driver of higher vitamin C requirements in the same way, and tends to enhance overall antioxidant defenses. A high calcium intake or a low-fat diet doesn’t directly increase vitamin C needs.
Question 5
What is the number one concern when addressing intimate partner violence?
Correct Answer:
Safety and creating a plan
Explanation:
Immediate safety and having a plan for leaving or reducing risk is the highest priority when addressing intimate partner violence. Ongoing violence can escalate quickly and create life-threatening situations, so the first goal is to protect the person in danger and help them establish a concrete safety plan. This includes assessing how imminent the danger is, identifying a safe place to go, arranging trusted contacts who can help, securing important documents and money, and preparing a go-bag with essentials and emergency numbers. Providers also help with practical steps like knowing where to seek shelter, how to contact authorities if needed, and what resources are available in the community, all while respecting the person’s autonomy and confidentiality. Financial resources, legal action, and counseling are important parts of long-term support, but they depend on the ability to stay safe and to engage with these options. Without safety, pursuing these avenues can be ineffective or even dangerous. Focusing on safety planning ensures the patient has a tangible, immediate path to reduce harm and regain control.
