Question 1 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 2 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 3 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 4 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.
Question 5 of 5
Mr. Marquez with rheumatoid arthritis is about to begin aspirin therapy to reduce inflammation. When teaching the client about aspirin, the nurse discusses adverse reactions to prolonged aspirin therapy. These include:
Correct Answer: D
Rationale: The correct answer is D: bilateral hearing loss. Aspirin, when used in high doses and for prolonged periods, can cause damage to the cochlea, leading to hearing loss. This is known as aspirin-induced hearing loss. Weight gain (choice A) is not a common adverse reaction of aspirin therapy. Fine motor tremors (choice B) are not typically associated with aspirin use. Respiratory acidosis (choice C) is not a recognized adverse reaction of aspirin therapy. Therefore, the most relevant and correct adverse reaction to prolonged aspirin therapy among the options provided is bilateral hearing loss.
