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 healthcare provider is caring for a child on bed rest who has severe edema in the left lower extremity due to blocked lymphatic drainage. Which nursing diagnosis would take priority?

• A. Risk for Impaired Skin Integrity
• B. Risk for Altered Body Image
• C. Risk for Imbalanced Nutrition: Less Than Body Requirements
• D. Risk for Activity Intolerance

Correct answer: A

Rationale: The priority nursing diagnosis in this scenario is 'Risk for Impaired Skin Integrity' because severe edema in the left lower extremity can lead to compromised circulation and pressure ulcers, increasing the risk of skin breakdown and infection. Addressing and preventing impaired skin integrity is crucial for the child's overall health and well-being.

3. A young child admitted to the pediatric unit has fever, irritability, and vomiting with suspected bacterial meningitis. Which cerebrospinal fluid (CSF) result should the nurse anticipate based on these data?

• A. Decreased protein count
• B. Clear, straw-colored fluid
• C. Positive for red blood cells (RBCs)
• D. Decreased glucose level

Correct answer: D

Rationale: In bacterial meningitis, the glucose level in the cerebrospinal fluid (CSF) is typically decreased due to the increased utilization of glucose by the infecting bacteria. This metabolic change leads to a decrease in CSF glucose levels, making choice D the correct answer in this scenario. Choices A, B, and C are incorrect because bacterial meningitis usually results in an increased protein count, cloudy appearance of the CSF due to the presence of bacteria, and absence of red blood cells (RBCs) in the CSF unless there is a traumatic tap, respectively.

4. What type of mode best describes Kasey's approach when meeting with the principal to change the cafeteria to better accommodate her client with difficulty eating in a noisy and distracting environment?

• A. Collaborating
• B. Instructing
• C. Advocating
• D. Encouraging

Correct answer: C

Rationale: Advocating best describes Kasey's approach in this scenario. Advocating involves presenting stories, research, and ideas to support and champion for a specific cause or individual, in this case, advocating for changes to better meet the child's needs in the cafeteria. Collaborating involves working together with others towards a common goal, instructing involves providing guidance or directions, and encouraging involves giving support or motivation, none of which fully capture Kasey's proactive and supportive advocacy actions in this context.

5. The healthcare provider discussed strategies with a parent to prevent a recurrence of urinary tract infection in the child. Which statement made by the parent indicates a need for further teaching?

• A. My daughter should wash and wipe the perineal area from front to back.
• B. I am only going to have my daughter wear cotton underwear.
• C. It is acceptable to take frequent bubble baths.
• D. She needs to drink lots of fluids and void frequently.

Correct answer: C

Rationale: The statement 'It is acceptable to take frequent bubble baths' indicates a need for further teaching. Oils in bubble bath and similar products can irritate the urethra, potentially leading to recurrent urinary tract infections. The other choices are correct: wiping from front to back helps prevent the spread of bacteria, wearing cotton underwear promotes breathability and reduces moisture, and drinking fluids and voiding frequently help flush out bacteria.
