Biological Basis of Behavior Quizlet Questions
Question 1 of 5
Nurse Len is teaching a group of women to perform BSE. The nurse should explain that the purpose of performing the examination is to discover:
Correct Answer: C
Rationale: The correct answer is C: Changes from previous examinations. The purpose of Breast Self-Examination (BSE) is to help women become familiar with the normal look and feel of their breasts so they can detect any changes early. By regularly performing BSE and comparing the findings to previous examinations, women can identify any new or unusual changes such as lumps, thickening, or other abnormalities that may indicate a potential health concern. This approach allows for early detection of breast abnormalities and promotes timely medical intervention if necessary. Choices A, B, and D focus on specific characteristics or conditions, but the primary goal of BSE is to identify changes over time.
Question 2 of 5
Kennedy with acute asthma showing inspiratory and expiratory wheezes and a decreased forced expiratory volume should be treated with which of the following classes of medication right away?
Correct Answer: B
Rationale: The correct answer is B: Bronchodilators. In acute asthma exacerbation, bronchodilators are crucial for immediate relief by dilating the airways and improving airflow. Beta-adrenergic blockers (A) are contraindicated in asthma as they can worsen bronchoconstriction. Inhaled steroids (C) are used for long-term control, not for immediate relief. Oral steroids (D) are used in severe asthma exacerbations that don't respond to bronchodilators, not as first-line treatment. Therefore, the immediate priority for Kennedy would be to administer bronchodilators to alleviate the acute symptoms.
Question 3 of 5
A 51-year-old female client tells the nurse in-charge that she has found a painless lump in her right breast during her monthly self-examination. Which assessment finding would strongly suggest that this client's lump is cancerous?
Correct Answer: B
Rationale: Correct Answer: B - Nonmobile mass with irregular edges Rationale: 1. Nonmobile mass indicates fixed growth, common in cancerous tumors. 2. Irregular edges suggest rapid, abnormal cell growth, characteristic of cancer. 3. These features raise suspicion for malignancy and warrant further investigation. Summary: A: Eversion of the right nipple and mobile mass - Typically seen in benign conditions like fibroadenomas. C: Mobile mass that is soft and easily delineated - Likely a benign cyst. D: Nonpalpable right axillary lymph nodes - Presence of palpable lymph nodes would suggest metastasis, not primary breast cancer.
Question 4 of 5
During a breast examination, which finding most strongly suggests that the Luz has breast cancer?
Correct Answer: B
Rationale: The correct answer is B. A fixed nodular mass with dimpling of the overlying skin is a classic sign of breast cancer due to infiltration of the skin by the tumor. This finding suggests an aggressive, invasive cancer. Choice A is common and often benign. Choice C can be a sign of cancer but is less specific. Choice D describes fibrocystic changes, which are benign.
Question 5 of 5
Which of the following statements explains the main difference between rheumatoid arthritis and osteoarthritis?
Correct Answer: B
Rationale: The correct answer is B: Osteoarthritis is a localized disease, while rheumatoid arthritis is systemic. In osteoarthritis, the degeneration of joint cartilage primarily affects specific joints, causing localized pain and stiffness. In contrast, rheumatoid arthritis is an autoimmune disease that affects the entire body, leading to inflammation in multiple joints and potentially impacting other organs. This fundamental difference in the scope of the diseases is crucial in distinguishing between them. Choices A, C, and D are incorrect because they do not accurately describe the main difference between rheumatoid arthritis and osteoarthritis.
