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. Which type of food is the most difficult to swallow?

• A. Raw Vegetables
• B. Strained Fruit
• C. Chopped Meat
• D. Mashed Vegetables

Correct answer: C

Rationale: Chopped meat is the most difficult to swallow as it requires thorough chewing and coordination to avoid swallowing hazards, making it more challenging compared to raw vegetables, strained fruit, and mashed vegetables.

3. A patient is 1 hour postoperative following an open reduction internal fixation of the left tibia. Which of the following actions should the nurse take?

• A. Assess neurovascular status of the extremities every 4 hours
• B. Monitor the patient's pain level every 8 hours
• C. Assist the patient to the bathroom every 2 hours
• D. Keep the patient's left leg elevated on two pillows

Correct answer: A

Rationale: The correct action for the nurse to take 1 hour postoperative following an open reduction internal fixation of the left tibia is to assess neurovascular status of the extremities every 4 hours. This frequent assessment is crucial to monitor for any signs of complications such as impaired circulation or nerve damage. Monitoring every 4 hours allows for early detection of any issues, enabling timely intervention and prevention of potential complications. Monitoring the patient's pain level every 8 hours (choice B) is not as immediate or essential for postoperative care. Assisting the patient to the bathroom every 2 hours (choice C) may not be necessary if the patient is not ambulatory yet. Keeping the patient's left leg elevated on two pillows (choice D) can be beneficial but is not the priority in the immediate postoperative period compared to assessing neurovascular status.

4. The healthcare professional is preparing to administer an immunization to a four-year-old child. Which of the following actions should the professional plan to take?

• A. Place the child in a prone position for the immunization
• B. Request that the child's caregiver stay in the room during the immunization
• C. Administer the immunization using a 24-gauge needle
• D. Inject the immunization slowly without aspirating

Correct answer: C

Rationale: When administering an immunization to a four-year-old child, it is important to use a 24-gauge needle to minimize pain and discomfort for the child. Thicker needles can cause more pain and tissue trauma. Using a thinner needle like a 24-gauge is appropriate for pediatric immunizations. Placing the child in a prone position for immunization is not recommended as it can be uncomfortable and may not allow for proper access to the injection site. Having the caregiver stay in the room during the immunization is beneficial for support and comfort for the child. Injecting the immunization slowly without aspirating is correct, as aspirating before administering the immunization is not required for intramuscular injections in current practice.

5. A nurse is providing teaching to the guardian of an infant about home safety. Which of the following statements by the guardian indicates an understanding of the teaching?

• A. I will place my baby on her stomach to sleep
• B. I will put a small pillow in my baby's crib
• C. I will keep my baby's crib away from the radiator
• D. I will use a drop-side crib for my baby

Correct answer: C

Rationale: The nurse should instruct the guardian to keep the baby�s crib away from the radiator to prevent burns.
