Nursing Elites

1. Women who have breast cancer due to a BRCA1 gene mutation are usually:

• A. positive for human epidermal growth factor receptor 1 and 2.
• B. negative for estrogen receptor.
• C. positive for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2.
• D. negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2.

Correct answer: D

Rationale: Women with breast cancer due to a BRCA1 gene mutation commonly have a triple-negative breast cancer subtype, which means they are negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2). This subtype tends to be more aggressive and harder to treat. Choice A is incorrect as they are typically negative for HER2. Choice B is incorrect because they are usually negative for estrogen receptor. Choice C is incorrect as they are usually negative for progesterone receptor and HER2.

2. What is the best method to identify which type of stroke the client has?

• A. Obtain a 12-lead electrocardiogram STAT
• B. Obtain a blood specimen for electrolytes and blood cultures
• C. Ask the client about current allergies
• D. Obtain a cranial computerized tomogram (CT) STAT

Correct answer: D

Rationale: The correct answer is to obtain a cranial computerized tomogram (CT) STAT. A cranial CT scan is the best method to quickly identify the type of stroke a client is experiencing. Options A, B, and C are not appropriate for identifying the type of stroke as they are not specific to assessing stroke types.

3. Which of the following describes the etiology of a cerebrovascular accident (CVA)?

• A. A blow to the head from a hard object
• B. Lack of blood flow to part of the brain
• C. Excessive exercise, such as running
• D. A ruptured artery in the heart

Correct answer: B

Rationale: The correct answer is B. A cerebrovascular accident (CVA), or stroke, is often caused by a lack of blood flow to part of the brain. This leads to damage in the brain tissue due to the deprived oxygen and nutrients. Choices A, C, and D are incorrect. A blow to the head from a hard object can cause a traumatic brain injury but is not the etiology of a CVA. Excessive exercise like running does not typically lead to a stroke. A ruptured artery in the heart may result in a heart attack, not a cerebrovascular accident.

4. Which of the following mediates humoral immunity?

• A. Natural killer cells
• B. T cells
• C. B cells
• D. Neutrophils

Correct answer: C

Rationale: Humoral immunity is mediated by B cells, not natural killer cells, T cells, or neutrophils. B cells are responsible for producing antibodies, which are essential components of humoral immunity.

5. A 30-year-old woman is taking an oral contraceptive and is concerned about the potential side effects. What should the nurse include in the patient education?

• A. Oral contraceptives can cause weight loss and increased energy levels.
• B. Oral contraceptives can cause increased appetite and weight gain.
• C. Oral contraceptives can cause headaches and breast tenderness.
• D. Oral contraceptives have no side effects.

Correct answer: C

Rationale: The correct answer is C: 'Oral contraceptives can cause headaches and breast tenderness.' It is essential for the nurse to educate the patient about common side effects of oral contraceptives, such as headaches and breast tenderness. Choices A, B, and D are incorrect. Weight loss and increased energy levels (Choice A) are not common side effects of oral contraceptives. Similarly, increased appetite and weight gain (Choice B) are not typical side effects. Finally, stating that oral contraceptives have no side effects (Choice D) is inaccurate as they can have various side effects, albeit usually mild and manageable.
