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. When educating a patient starting on oral contraceptives, what should the nurse include regarding the medication's effectiveness?
- A. Oral contraceptives are 100% effective when taken correctly.
- B. Oral contraceptives are effective immediately after starting.
- C. Oral contraceptives are less effective if taken with antibiotics.
- D. Oral contraceptives are less effective if taken with food.
Correct answer: C
Rationale: The correct answer is C. Oral contraceptives can be less effective when taken with certain antibiotics as they may interfere with the contraceptive's efficacy, potentially leading to decreased effectiveness. Therefore, patients should be advised to use additional contraception methods if they are also taking antibiotics. Choice A is incorrect because while oral contraceptives are highly effective, they are not 100% foolproof. Choice B is incorrect as oral contraceptives may take some time to reach their full effectiveness after starting. Choice D is incorrect since taking oral contraceptives with food does not necessarily impact their effectiveness.
3. Which of the following is an example of a Type 1 hypersensitivity reaction?
- A. Anaphylaxis
- B. Indigestion
- C. Beta cell destruction
- D. ABO transfusion reaction
Correct answer: A
Rationale: Anaphylaxis is a classic example of a Type 1 hypersensitivity reaction. In Type 1 hypersensitivity, allergens trigger an immediate immune response mediated by IgE antibodies, leading to the release of histamine and other mediators. This reaction can result in symptoms ranging from mild itching and hives to severe conditions like anaphylaxis, which is a life-threatening emergency. The other options, such as indigestion (choice B), beta cell destruction (choice C), and ABO transfusion reaction (choice D), are not classified as Type 1 hypersensitivity reactions. Indigestion is typically related to gastrointestinal disturbances, beta cell destruction is associated with autoimmune conditions like type 1 diabetes, and ABO transfusion reaction involves antibodies targeting incompatible blood groups, which is a different immune mechanism compared to Type 1 hypersensitivity.
4. A client presents to the emergency department with complaints of chest pain and shortness of breath. The client's ECG shows ST-segment elevation. What is the priority nursing intervention?
- A. Administer aspirin as prescribed.
- B. Prepare the client for emergent coronary angiography.
- C. Administer oxygen therapy.
- D. Initiate CPR.
Correct answer: B
Rationale: In a client presenting with chest pain, shortness of breath, and ST-segment elevation on ECG, the priority nursing intervention is to prepare the client for emergent coronary angiography. This procedure is crucial in diagnosing and treating acute myocardial infarction promptly. Administering aspirin (Choice A) is important but not the priority over emergent coronary angiography. Administering oxygen therapy (Choice C) is supportive but does not address the underlying cause of the ST-segment elevation. Initiating CPR (Choice D) is not the priority in this scenario as the client is stable and conscious.
5. A client has experienced a pontine stroke which has resulted in severe hemiparesis. What priority assessment should the nurse perform prior to allowing the client to eat or drink from the food tray?
- A. Evaluate the client's gag reflex.
- B. Assess the client's bowel sounds.
- C. Check the client's pupil reaction.
- D. Monitor the client's heart rate.
Correct answer: A
Rationale: The correct answer is to evaluate the client's gag reflex. When a client has experienced a stroke resulting in severe hemiparesis, assessing the gag reflex is crucial before allowing them to eat or drink. This assessment helps prevent aspiration, a serious complication that can occur due to impaired swallowing ability. Assessing bowel sounds (Choice B), pupil reaction (Choice C), or heart rate (Choice D) are important assessments but are not the priority in this situation where the risk of aspiration is higher.
