1. The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?

• A. Angiotensin I
• B. Angiotensin II
• C. Angiotensin III
• D. Renin

Correct answer: B

Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.

2. A patient with Parkinson�s disease who takes levodopa/carbidopa (Sinemet) comes to the clinic for a semi-annual physical examination. Which question is the most important for that nurse to ask?

• A. Have you noticed any swelling in your feet?
• B. Are you having vivid dreams or hallucination?
• C. Have you noticed any changes in your stool?
• D. Have you had your flu vaccine?

Correct answer: B

Rationale: Patients taking levodopa/carbidopa (Sinemet) are at increased risk for the psychiatric side effects of levodopa, including visual hallucinations, vivid dreams, nightmares, and paranoid ideation. The other questions are not directly related to problems that are likely to occur with this drug.

3. The nurse is planning care for a school-age client who is postoperative for the surgical removal of the appendix. In addition to pharmacologic pain management, what should the nurse include in the plan of care to address pain?

• A. Applying a warm, moist pack every 4 hours
• B. Applying EMLA cream to the incision site prior to ambulation
• C. Applying a cold, moist pack every 2 hours
• D. Applying a pillow against the abdomen to splint the incision site when coughing

Correct answer: D

Rationale: After an appendectomy, applying a pillow against the abdomen to splint the incision site when coughing helps reduce pain by providing support and minimizing movement that could cause discomfort.

4. A preschool-age child is admitted to the hospital with acute postinfectious glomerulonephritis (APIGN). Which is the priority nursing diagnosis for this child?

• A. Risk for Injury related to hypertension.
• B. Altered Growth and Development related to chronic disease.
• C. Risk for Infection related to hypertension.
• D. Fluid Volume Excess related to decreased plasma filtration.

Correct answer: A

Rationale: The priority nursing diagnosis for a preschool-age child with acute postinfectious glomerulonephritis (APIGN) is 'Risk for Injury related to hypertension' due to the potential complications such as hypertensive encephalopathy. Hypertension poses an immediate threat to the child's well-being, making it crucial to address the risk for injury associated with elevated blood pressure as the top priority.

5. 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.
