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. The 6-year-old child scheduled for an orchiopexy shyly asks the nurse, 'What are they going to do to me 'down there'? What is the nurse's best response?

• A. They are going to fix you up 'down there'.
• B. They will move your testicle from your abdomen to your scrotum.
• C. What do you think your doctor is going to do?
• D. You shouldn't worry. Your doctor knows exactly what to do.

Correct answer: C

Rationale: The nurse should encourage the child to express his thoughts and feelings about the upcoming surgery. This approach helps the child feel heard and understood while providing an opportunity to address any misconceptions or fears. By asking the child what he thinks the doctor will do, the nurse engages the child in a conversation that can help alleviate anxiety and build trust. School-age children often have fears related to bodily harm, and open communication can help alleviate such concerns. Choices A and D do not encourage open communication or address the child's concerns directly. Choice B provides too much detail that may overwhelm the child and is not age-appropriate for a 6-year-old.

3. 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.

4. A healthcare provider is assessing an infant who has hydrocephalus and is 6 hours postoperative following placement of a ventriculoperitoneal shunt. Which of the following findings should the provider report to the healthcare provider?

• A. Decreased urine output
• B. Temperature of 37.5 degrees C (99.5 degrees F)
• C. Heart rate 130/min
• D. Leakage of cerebrospinal fluid

Correct answer: D

Rationale: The provider should report the leakage of cerebrospinal fluid to the healthcare provider as it may indicate shunt malfunction or infection, requiring immediate attention to prevent complications. Decreased urine output, a temperature of 37.5 degrees C, and a heart rate of 130/min are common postoperative findings and may not be directly related to shunt function. While these findings should still be monitored, they do not require immediate reporting like cerebrospinal fluid leakage.

5. Which type of play involves actions such as looking and touching the mother's face, putting hands in one's mouth, and responding to familiar people?

• A. Exploratory
• B. Functional or relational
• C. Pretend
• D. Symbolic or imaginary

Correct answer: A

Rationale: Exploratory play is characterized by exploring sensory experiences and learning about the environment. In this type of play, infants engage in activities like looking, touching, and responding to familiar stimuli to understand the world around them.
