Nursing Elites

1. What physiological reaction occurs in the body with the 'Fight or flight' response?

• A. Increased heart rate
• B. Constricted pupils
• C. Decreased blood pressure
• D. Decreased heart rate

Correct answer: A

Rationale: The 'fight or flight' response is a primal physiological reaction that prepares the body to respond to a perceived threat or danger. This response triggers an increase in heart rate to pump more blood to the muscles and vital organs, preparing the body for action. Choice B, 'Constricted pupils,' is part of the 'fight or flight' response as well, as it helps improve focus and vision. Choice C, 'Decreased blood pressure,' is incorrect because blood pressure typically increases to ensure adequate circulation during the 'fight or flight' response. Choice D, 'Decreased heart rate,' is incorrect as the heart rate increases to supply more oxygen and nutrients to the body during times of stress.

2. What causes type I diabetes?

• A. Overproduction of insulin from the beta cells of the pancreas
• B. Destruction of the beta cells within the pancreas, resulting in an inability to produce insulin
• C. Loss of insulin receptors on the target cells, resulting in insulin resistance
• D. A pituitary tumor in the brain, resulting in increased antidiuretic hormone production

Correct answer: B

Rationale: Type I diabetes is caused by the destruction of the beta cells in the pancreas, leading to an inability to produce insulin. This results in a lack of insulin, leading to hyperglycemia. Choice A is incorrect as type I diabetes is characterized by a deficiency of insulin production, not overproduction. Choice C describes the pathophysiology of type 2 diabetes, where insulin receptors become less responsive to insulin. Choice D is unrelated to type I diabetes as it describes a pituitary tumor causing increased antidiuretic hormone production.

3. Which of the following women is at highest risk for the development of endometrial cancer?

• A. A 50-year-old postmenopausal woman with a history of high-risk human papillomavirus
• B. A 45-year-old woman who is obese and has a menstrual pattern consisting of periods of amenorrhea and infrequent periods
• C. A 40-year-old woman who is overweight and has hypertension
• D. A 55-year-old woman who smokes

Correct answer: B

Rationale: The correct answer is a 45-year-old woman who is obese and has a menstrual pattern consisting of periods of amenorrhea and infrequent periods. Obesity and prolonged exposure to estrogen unopposed by progesterone due to infrequent ovulation are significant risk factors for endometrial cancer. Choices A, C, and D do not directly correlate with the increased risk of endometrial cancer. Postmenopausal status alone (Choice A), overweight with hypertension (Choice C), and smoking (Choice D) are not the primary risk factors for endometrial cancer.

4. What long-term risks should the nurse discuss with a patient being treated with hormone replacement therapy (HRT) for menopausal symptoms?

• A. HRT may increase the risk of cardiovascular events and breast cancer.
• B. HRT may decrease the risk of osteoporosis.
• C. HRT may improve mood and energy levels.
• D. HRT may increase the risk of venous thromboembolism.

Correct answer: A

Rationale: The correct answer is A. Long-term hormone replacement therapy (HRT) is associated with increased risks of cardiovascular events and breast cancer. These risks should be discussed with the patient to ensure they are aware of the potential adverse effects. Choice B is incorrect because HRT does not decrease the risk of osteoporosis; in fact, it has been linked to an increased risk of this condition. Choice C is incorrect as while HRT may have positive effects on mood and energy levels for some individuals, the focus here is on the long-term risks that need to be addressed. Choice D is incorrect as HRT is indeed associated with an increased risk of venous thromboembolism, but the primary focus of the question is on cardiovascular events and breast cancer.

5. A patient with a history of breast cancer is prescribed tamoxifen (Nolvadex). What critical information should the nurse include in the patient education?

• A. Tamoxifen may increase the risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots.
• B. Tamoxifen may cause weight gain, so patients should monitor their diet.
• C. Tamoxifen may decrease the risk of osteoporosis, so patients should ensure adequate calcium intake.
• D. Tamoxifen may cause hot flashes and other menopausal symptoms.

Correct answer: A

Rationale: Tamoxifen increases the risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots and the importance of seeking immediate medical attention if they occur.
