Biological Basis of Behavior Quizlet Questions
Question 1 of 5
The nurse is caring for Kenneth experiencing an acute asthma attack. The client stops wheezing and breath sounds aren't audible. The reason for this change is that:
Correct Answer: B
Rationale: The correct answer is B. When the client stops wheezing and breath sounds are not audible during an acute asthma attack, it indicates that the airways are so swollen that no air can get through. This is a sign of severe airway constriction, which can be life-threatening. The other choices are incorrect because: A, the attack is not over as the symptoms indicate a worsening condition; C, the swelling decreasing would not cause the absence of breath sounds; D, crackles are typically heard in conditions like pneumonia, not in asthma attacks.
Question 2 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 3 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 4 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.
Question 5 of 5
Nurse Trinity administered neutral protamine Hagedorn (NPH) insulin to a diabetic client at 7 a.m. At what time would the nurse expect the client to be most at risk for a hypoglycemic reaction?
Correct Answer: C
Rationale: The correct answer is C (16:00) because NPH insulin typically peaks around 4-12 hours after administration. Since NPH insulin was given at 7 a.m., the peak effect would likely occur around 4 p.m. This timing increases the risk of hypoglycemia as the insulin's potency is at its highest, potentially causing a sudden drop in blood sugar levels. The other choices (A, B, and D) are incorrect because they do not align with the expected peak time for NPH insulin, which is crucial in determining the client's vulnerability to hypoglycemia.
