Q1A 65-year-old female is experiencing severe shortness of breath and chest pain after climbing a flight of stairs. She appears very distressed and insists on going to the hospital immediately. The patient is sitting on her living room couch, and your stretcher is outside by the ambulance. You are trying to manage her anxiety and stabilize her condition to avoid a potential cardiac arrest. Which of the following would not be appropriate care in this situation?
Show answer
✓ Correct answer: Ask the patient to walk to the stretcher
Answer: Ask the patient to walk to the stretcher In a patient with severe shortness of breath and chest pain, exerting any further effort could lead to worsening of her condition or even cardiac arrest. The stretcher should be brought to the patient, or she should be carefully carried to it. Keeping her calm and minimizing physical exertion is crucial. Instead, place the patient in a comfortable position and assist her with taking aspirin if appropriate. Physical reassurance like holding her hand or touching her shoulder can also help make her feel more relaxed if she permits it.
Q2Which condition was formerly referred to as toxemia during pregnancy?
Show answer
✓ Correct answer: Preeclampsia
Answer: Preeclampsia Preeclampsia (formerly known as toxemia) is a condition characterized by high blood pressure and signs of damage to another organ system, often the kidneys, during pregnancy. Symptoms of preeclampsia include severe headaches, changes in vision, upper abdominal pain, and swelling of the hands and feet. Eclampsia is a severe complication of preeclampsia that includes the same symptoms as preeclampsia along with seizures. Gestational diabetes is a form of high blood sugar affecting pregnant women who have never had diabetes before. Hyperemesis gravidarum is a severe form of nausea and vomiting during pregnancy, which can lead to dehydration and weight loss.
Q3While performing CPR on a patient, you discover an implanted pacemaker where you need to place the AED pad. What is the appropriate action to take?
Show answer
✓ Correct answer: Place the AED pad at least one inch away from the pacemaker
Answer: Place the AED pad at least one inch away from the pacemaker When a patient has an implanted pacemaker, the AED pad should be placed at least one inch away from the device. Placing the pad directly over the pacemaker can disrupt the function of the pacemaker and may not deliver an effective shock. Do not remove the pacemaker.
Q4What is the definition of a premature birth?
Show answer
✓ Correct answer: The birth of a baby before 37 weeks of gestation
Answer: The birth of a baby before 37 weeks of gestation A premature birth, also known as preterm birth, occurs when a baby is born before 37 completed weeks of gestation. Such births can lead to various health complications for the baby, including respiratory issues, gastrointestinal problems, and developmental delays. Accurate identification of premature birth is essential for the implementation of appropriate medical interventions and care.
Q5For a mother who just delivered a baby, how frequently should her vital signs be monitored during the immediate postpartum period?
Show answer
✓ Correct answer: Every 15 minutes
Correct answer: Every 15 minutes After a mother has delivered a baby, it is essential to monitor her vital signs every 15 minutes during the immediate postpartum period. This frequent monitoring helps ensure the mother is not experiencing any complications such as postpartum hemorrhage or hypertension. In contrast, checking vital signs too frequently (e.g., every 5 minutes) can be overwhelming and unnecessary, while less frequent checks (e.g., every 30 minutes) might delay the identification of emergent issues.
Q6Which type of heart chamber in the human body has the thickest walls?
Show answer
✓ Correct answer: Left ventricle
Answer: Left ventricle The left ventricle has the thickest walls of all the heart chambers because it needs to pump blood to the entire body, requiring great force. The right ventricle has thinner walls compared to the left ventricle as it only pumps blood to the lungs. The atria, both right and left, have thinner walls as they only need to pump blood to the ventricles and do not require as much force.
