Nursing Elites

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 nurse administers naloxone (Narcan) to a post-op patient experiencing respiratory sedation. What undesirable effect would the nurse anticipate after giving this medication?

• A. Drowsiness
• B. Tics and tremors
• C. Increased Pain
• D. Nausea and vomiting

Correct answer: C

Rationale: Naloxone reverses the effects of narcotics. Although the patient�s respiratory status will improve after administration of naloxone, the pain will be more acute.

3. A nurse is providing discharge teaching to the parent of a child who has juvenile idiopathic arthritis. Which of the following statements should the nurse include?

• A. Encourage the child to sleep for 8 hours each night.
• B. Perform range-of-motion exercises once per week.
• C. Give your child NSAIDs on a regular schedule.
• D. Apply heat to the child's affected joints twice daily.

Correct answer: C

Rationale: The nurse should instruct the parent to give the child NSAIDs on a regular schedule to maintain therapeutic levels and control pain.

4. A nurse is planning care for a school-age child who has thrombocytopenia. Which of the following interventions should the nurse include in the plan?

• A. Administer aspirin as needed for fever.
• B. Avoid venipunctures whenever possible.
• C. Encourage the child to participate in contact sports.
• D. Administer ibuprofen for pain.

Correct answer: B

Rationale: The correct answer is B: 'Avoid venipunctures whenever possible.' Thrombocytopenia is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. Venipunctures can cause bleeding in these patients; therefore, they should be avoided whenever possible. Choice A is incorrect because aspirin should be avoided in patients with thrombocytopenia as it can further increase the risk of bleeding due to its antiplatelet effects. Choice C is incorrect because participating in contact sports can also increase the risk of injury and bleeding in a child with thrombocytopenia. Choice D is incorrect as ibuprofen, like aspirin, can also increase the risk of bleeding and should be avoided in these patients.

5. 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.
