1. Following a stroke, a client has been started on clopidogrel (Plavix). Why is this medication being administered?
- A. To prevent stroke in high-risk patients, such as those with prosthetic heart valves
- B. To decrease blood pressure
- C. To increase heart rate
- D. To provide antiplatelet activity in patients who cannot tolerate aspirin
Correct answer: D
Rationale: Clopidogrel (Plavix) is an antiplatelet medication that inhibits platelet aggregation, reducing the risk of blood clots. It is commonly used in patients who have had a stroke and cannot tolerate aspirin due to allergies or intolerances. Choosing clopidogrel in these cases helps prevent further clot formation and reduces the risk of recurrent strokes.
2. Joseph, a 12-year-old child, complains to the school nurse about nausea and dizziness. While assessing the child, the nurse notices a black eye that looks like an injury. This is the third time in 1 month that the child has visited the nurse. Each time, the child provides vague explanations for various injuries. Which of the following is the school nurse’s priority intervention?
- A. Contact the child’s parents and ask about the child’s injuries.
- B. Encourage the child to be honest about the injuries.
- C. Question the teacher about the child's injuries.
- D. Report suspicion of abuse to the proper authorities.
Correct answer: D
Rationale: The school nurse's priority intervention in this situation is to report suspicion of abuse to the proper authorities. Given the pattern of unexplained injuries and vague explanations provided by the child, it raises significant concerns for possible abuse. Reporting to the appropriate authorities is crucial to ensure the child's safety and well-being. Contacting the child's parents (Choice A) may not be appropriate if abuse is suspected, as it could potentially put the child at further risk. Merely encouraging the child to be honest (Choice B) does not address the immediate safety concerns. Questioning the teacher (Choice C) is not the appropriate initial action when abuse is suspected; reporting to authorities should take precedence.
3. Which condition is characterized by the right ventricle of the heart failing due to increased pressure in the lungs, often caused by chronic lung disease?
- A. Cor pulmonale
- B. Pulmonary embolism
- C. Aortic stenosis
- D. Hypertrophic cardiomyopathy
Correct answer: A
Rationale: The correct answer is Cor pulmonale, a condition where the right ventricle of the heart fails due to increased pressure in the lungs, commonly caused by chronic lung diseases like COPD. Pulmonary embolism (choice B) is a blockage in one of the pulmonary arteries in the lungs, usually caused by a blood clot. Aortic stenosis (choice C) is a narrowing of the aortic valve opening that restricts blood flow from the left ventricle to the aorta. Hypertrophic cardiomyopathy (choice D) is a genetic condition where the heart muscle becomes abnormally thick, making it harder for the heart to pump blood.
4. Each statement is true of fat-soluble vitamins, except one. Which is the exception?
- A. Fairly stable to heat, such as during cooking
- B. Contain carbon
- C. Stored in the pancreas
- D. Absorbed in the intestine along with fats and lipids in food
Correct answer: C
Rationale: Fat-soluble vitamins are not stored in the pancreas; they are stored in the liver and fatty tissues. Choice A is correct as fat-soluble vitamins are fairly stable to heat. Choice B is also correct as fat-soluble vitamins contain carbon. Choice D is correct as fat-soluble vitamins are absorbed in the intestine along with fats and lipids in food.
5. A nurse is planning care for a client who had gastric bypass surgery 1 week ago and has signs of early dumping syndrome. Which of the following findings should the nurse expect?
- A. Facial flushing
- B. Syncope
- C. Diaphoresis
- D. Bradycardia
Correct answer: A
Rationale: Facial flushing is a common symptom of early dumping syndrome, which occurs when food moves too quickly into the small intestine. This rapid movement triggers the release of vasoactive peptides causing vasodilation, leading to facial flushing. Syncope (choice B) is not a typical finding in early dumping syndrome. Diaphoresis (choice C) and bradycardia (choice D) are also not characteristic symptoms of early dumping syndrome.
