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 nurse is reviewing the prescriber�s orders and notes that omeprazole has been order for a patient admitted with acute coronary syndrome (ACS). The nurse should be concerned if this medication is combined with which medication noted on the patient�s record.

• A. Aspirin 81mg daily
• B. Clopidogrel (Plavix) 75mg daily
• C. Heparin 5000 units subQ q12hrs
• D. Metoprolol 50mg q8hrs

Correct answer: B

Rationale: For patients who lack risk factors for GI bleeding, combined use of clopidogrel with a PPI, may reduce the effects of clopidogrel without offering any real benefits and thus should be avoided.

3. A healthcare professional is performing hearing screenings for children at a community health fair. Which of the following children should the professional refer to a provider for a more extensive hearing evaluation?

• A. A toddler who is 18 months old and has unintelligible speech
• B. An infant who is 3 months old and has an exaggerated startle response
• C. A preschooler who is 4 years old and prefers playing with others rather than alone
• D. An infant who is 8 months old and is not yet making babbling sounds

Correct answer: D

Rationale: The healthcare professional should refer an infant who is not making babbling sounds by the age of 7 months to a provider for a more extensive evaluation of hearing. Babbling sounds are a developmental milestone that typically occurs by 7 months of age. Delayed or absent babbling can indicate potential hearing issues that warrant further assessment.

4. A patient develops hypotension, laryngeal edema, and bronchospasm after eating peanuts. Which medication should the nurse prepare to administer?

• A. Promethazine
• B. Epinephrine
• C. Diphenhydramine
• D. Hydroxyzine

Correct answer: B

Rationale: The patient is exhibiting symptoms of anaphylaxis triggered by a peanut allergy, a severe and potentially life-threatening allergic reaction. The appropriate medication for anaphylaxis is epinephrine. Epinephrine acts quickly to reverse the symptoms by constricting blood vessels, relaxing bronchial muscles, and reducing laryngeal edema, making it the drug of choice for this situation. Promethazine, diphenhydramine, and hydroxyzine are not the first-line treatments for anaphylaxis. Promethazine is an antihistamine with sedative effects, Diphenhydramine is an antihistamine, and Hydroxyzine is also an antihistamine with sedative properties. While these medications can help with mild allergic reactions, they are not as effective or fast-acting as epinephrine in treating the severe manifestations of anaphylaxis.

5. During a developmental screening, a 4-year-old child is asked to perform a task. Which of the following tasks should the nurse expect the child to perform?

• A. Draw a stick figure with seven body parts
• B. Draw a circle
• C. Identify right from left hand
• D. Tie their shoelaces

Correct answer: B

Rationale: At 4 years old, children are typically able to draw a circle, which is a developmental milestone for their age. Drawing a stick figure with specific body parts might be beyond their developmental level, identifying right from left hand can be challenging, and tying shoelaces requires more advanced motor skills.
