With myocardial ischemia a person lacks

Correct Answer: A

Rationale: Step-by-step rationale: 1. Myocardial ischemia is a condition where the heart muscle doesn't receive enough oxygen. 2. Oxygen is crucial for the heart to function properly and generate energy. 3. Lack of oxygen can lead to chest pain (angina) or a heart attack. 4. Therefore, with myocardial ischemia, the person lacks oxygen, making choice A correct. Summary: - Choice A (Oxygen) is correct as myocardial ischemia involves oxygen deficiency. - Choices B, C, and D are incorrect as they are not directly related to the lack of oxygen in myocardial ischemia.

Correct Answer: B

Rationale: The correct answer is B (70 to 100 mg/dl). This range is considered normal for a person without diabetes as it reflects healthy blood glucose levels. Values below 70 may indicate hypoglycemia, while values above 100 may indicate prediabetes or diabetes. Choice A is too low and suggestive of hypoglycemia. Choices C and D are too high and indicate hyperglycemia, which is not normal for someone without diabetes. Therefore, B is the correct answer based on the typical fasting blood glucose range for a healthy individual.

Correct Answer: A

Rationale: The correct answer is A: Bleeding gums. HIV/AIDS can weaken the immune system, leading to oral health issues such as bleeding gums. Pressure injuries, jaundice, and changes in moles are not typical signs or symptoms of HIV/AIDS. Bleeding gums can result from gum disease, a common oral manifestation in individuals with HIV/AIDS due to compromised immunity. Regular dental check-ups are essential for early detection and management.

Correct Answer: B

Rationale: The correct answer is B: Finger. A pulse oximeter measures oxygen saturation in the blood by clipping onto a person's finger. The finger is chosen because it is easily accessible, has good blood flow, and provides accurate readings. Clipping the sensor on the neck (A) is incorrect as it may obstruct blood flow and provide inaccurate readings. The stomach (C) and lower arm (D) are also not ideal locations as they do not have as strong blood flow as the finger, leading to less accurate results.

Correct Answer: C

Rationale: The correct answer is C: Makes eye contact during the interview. Eye contact is essential for building rapport and showing confidence. It demonstrates attentiveness and credibility to the interviewer. It also signifies respect and genuine interest in the conversation. Incorrect answers: A: Exaggerating accomplishments can lead to dishonesty and harm credibility. B: Arriving on time is important, but arriving when the interview is starting is considered late. D: Bringing a family member for support is unprofessional and can give the impression of dependency or lack of confidence.
