Nursing Elites

1. When caring for premature newborns in an intensive care setting, a nurse carefully monitors oxygen concentration. What is the most common complication of this therapy?

• A. Intraventricular hemorrhage
• B. Retinopathy of prematurity
• C. Bronchopulmonary dysplasia
• D. Necrotizing enterocolitis

Correct answer: B

Rationale: Retinopathy of prematurity is the most common complication in premature infants exposed to high concentrations of oxygen. This condition leads to abnormal blood vessel growth in the retina, which can potentially result in blindness if not managed promptly. Intraventricular hemorrhage, though a significant concern in premature infants, is not directly related to oxygen therapy. Bronchopulmonary dysplasia is primarily associated with mechanical ventilation and oxygen exposure over time, not specifically with oxygen concentration monitoring. Necrotizing enterocolitis is more linked to gastrointestinal issues and is not the most common complication of oxygen therapy in premature newborns.

2. Which of the following activities is an example of tertiary prevention?

• A. Health education
• B. Regular exercise
• C. Screening tests
• D. Physical therapy

Correct answer: D

Rationale: The correct answer is D, physical therapy. Tertiary prevention focuses on rehabilitation and treatment to prevent complications from a disease or injury. Physical therapy falls under this category as it helps individuals recover and improve functionality after an illness or injury. Choices A, B, and C are not examples of tertiary prevention. Health education (choice A) is more aligned with primary prevention by promoting healthy behaviors to prevent disease onset. Regular exercise (choice B) can be categorized under both primary and secondary prevention as it aims to prevent disease development and detect conditions early. Screening tests (choice C) are part of secondary prevention as they aim to detect diseases at an early stage for prompt treatment.

3. While caring for a client with infective endocarditis, the nurse must be alert for signs of pulmonary embolism. Which of the following assessment findings suggests this complication?

• A. Positive Homan's sign
• B. Fever and chills
• C. Dyspnea and cough
• D. Sensory impairment

Correct answer: C

Rationale: The correct answer is C: 'Dyspnea and cough.' Pulmonary embolism often presents with a sudden onset of dyspnea (difficulty breathing) and cough, which are due to the obstruction of blood flow in the pulmonary arteries. Choices A, B, and D are incorrect. Positive Homan's sign is associated with deep vein thrombosis, fever and chills are nonspecific symptoms commonly seen in infective endocarditis, and sensory impairment is not typically indicative of pulmonary embolism.

4. The nurse is teaching a client with cardiac disease about the anatomy and physiology of the heart. Which is the correct pathway of blood flow through the heart?

• A. Right ventricle, left ventricle, right atrium, left atrium
• B. Left ventricle, right ventricle, left atrium, right atrium
• C. Right atrium, right ventricle, left atrium, left ventricle
• D. Right atrium, left atrium, right ventricle, left ventricle

Correct answer: C

Rationale: The correct pathway of blood flow through the heart starts with blood entering the right atrium, moving to the right ventricle, then to the lungs for oxygenation, returning to the left atrium, and finally to the left ventricle before being pumped out to the body. Option A is incorrect as it starts with the ventricles instead of the atria. Option B is incorrect as it has the sequence of ventricles before atria reversed. Option D is incorrect as it has the atria and ventricles mixed up.

5. What is the most common cause of vaginal bleeding immediately after birth?

• A. Uterine atony
• B. Genital lacerations
• C. Abnormal clotting mechanism
• D. Endometritis

Correct answer: A

Rationale: Vaginal bleeding immediately after birth is most often due to uterine atony, which is the failure of the uterus to contract following delivery. This results in inadequate compression of blood vessels at the placental site, leading to hemorrhage. Genital lacerations and abnormal clotting mechanisms can also cause bleeding but are less common immediately after birth compared to uterine atony. Endometritis, inflammation of the lining of the uterus, usually presents with symptoms like fever and pelvic pain rather than immediate postpartum bleeding.
