1. Which risk factors increase the risk of atherosclerosis?
- A. Exercise
- B. Excessive sun exposure
- C. Insufficient vaccinations
- D. Smoking
Correct answer: D: Smoking
Rationale: Smoking is a major risk factor for atherosclerosis. It significantly contributes to the buildup of plaque in the arteries and thereby increases the risk of cardiovascular diseases. On the other hand, exercise is generally beneficial for cardiovascular health and is not a risk factor for atherosclerosis. Excessive sun exposure and insufficient vaccinations have no established links to atherosclerosis, making them incorrect options for this question.
2. Which of the following is not an effect of the drug isoflurane?
- A. Elevated lipid levels
- B. Nausea
- C. Increased blood flow to the brain
- D. Decreased respiratory function
Correct answer: A
Rationale: Isoflurane is not known to cause elevated lipid levels. Common effects of isoflurane include nausea, increased blood flow to the brain, and decreased respiratory function. Elevated lipid levels are not typically associated with the administration of isoflurane, making choice A the correct answer.
3. Parents are speaking with the urologist about their son's undescended testicle. Which statement by the child's father causes the nurse to determine he understands the information presented?
- A. An undescended testicle can reduce fertility.
- B. The testicle usually descends spontaneously during the first month of life.
- C. Surgical correction reduces the risk for testicular tumors.
- D. The optimal time to surgically correct the condition is at diagnosis.
Correct answer: A
Rationale: The correct answer is A because an undescended testicle can reduce fertility. Even after surgical correction (orchiopexy), fertility rates may be reduced, especially when one testis remains undescended. The statement in choice B is incorrect as the testicle should have descended into the scrotum by the time the infant is 4-6 months old. While choice C is true that surgical correction can reduce the risk of testicular tumors, the question focuses on the father's understanding of the information presented, which is better reflected in choice A. Choice D is incorrect because the optimal time for surgical correction of an undescended testicle is typically around 6-18 months of age, not necessarily at the time of diagnosis.
4. Which hormone reduces the amount of water in the body?
- A. ADH
- B. aldosterone
- C. ANH
- D. ADH and aldosterone
Correct answer: B
Rationale: The correct answer is 'aldosterone.' Aldosterone is the hormone that reduces the amount of water in the body by increasing the reabsorption of sodium and water from the kidney tubules. ANH (atrial natriuretic hormone) actually works to increase the excretion of sodium and water by the kidneys, leading to a reduction in blood volume and pressure. ADH (antidiuretic hormone) works to increase water reabsorption by the kidneys, thereby increasing blood volume. Therefore, choices A (ADH) and D (ADH and aldosterone) are incorrect in the context of reducing the amount of water in the body.
5. The nurse is developing a plan of care for the client with multiple myeloma and includes which priority intervention in the plan?
- A. Encouraging fluids
- B. Providing frequent oral care
- C. Coughing and deep breathing
- D. Monitoring the red blood cell count
Correct answer: A
Rationale: The correct answer is A: Encouraging fluids. In a client with multiple myeloma, encouraging fluids is a priority intervention to prevent kidney damage from high calcium levels. Adequate hydration helps maintain renal function and prevents complications. Providing frequent oral care (Choice B) is essential for clients at risk of mucositis or oral infections, such as those undergoing chemotherapy. Coughing and deep breathing exercises (Choice C) are commonly used for clients at risk of respiratory complications, like postoperative patients. Monitoring the red blood cell count (Choice D) is important for conditions like anemia but is not the priority in a client with multiple myeloma, where fluid management is crucial.
