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 statement best describes the use of activity or task analysis?

• A. A foundational tool in occupational therapy for over a century
• B. A technique used to evaluate motor deficits in pediatrics
• C. Recently applied in some areas of pediatric occupational therapy
• D. A tool used exclusively by occupational therapy practitioners

Correct answer: A

Rationale: The correct answer is A: 'A foundational tool in occupational therapy for over a century.' Activity or task analysis has been a fundamental method in occupational therapy for a long time. It involves breaking down activities or tasks into smaller components to understand the skills required and identify areas of difficulty. This process helps occupational therapists develop effective intervention strategies to improve a client's ability to perform daily activities independently. Choices B, C, and D are incorrect because activity or task analysis is not limited to evaluating motor deficits in pediatrics, recently applied only in some areas of pediatric occupational therapy, or exclusively used by occupational therapy practitioners. It is a widely used and established method in the field of occupational therapy.

3. A healthcare professional is planning care for an infant who has a colostomy. Which of the following actions should the healthcare professional take?

• A. Change the ostomy pouch every day.
• B. Use baby wipes to clean the stoma.
• C. Avoid using soap to clean the stoma.
• D. Apply barrier ointment to the skin around the stoma.

Correct answer: D

Rationale: When caring for an infant with a colostomy, it is essential to apply barrier ointment to the skin around the stoma. This helps in preventing skin breakdown and irritation caused by exposure to stool or urine. Changing the ostomy pouch as needed, using appropriate cleaning supplies such as warm water and mild soap (avoiding harsh chemicals like alcohol), and ensuring gentle cleaning of the stoma with a soft cloth or gauze are also important steps in colostomy care. Using baby wipes may not be recommended as they can contain chemicals that may irritate the sensitive skin around the stoma.

4. Which statement regarding the human papillomavirus vaccine (Gardasil) is true?

• A. Gardasil is administered in a two-dose series.
• B. Gardasil provides protection against chlamydia.
• C. Gardasil is recommended for males and females.
• D. Gardasil becomes effective after the first dose.

Correct answer: C

Rationale: Gardasil is recommended for both males and females to protect against HPV and related conditions such as genital warts and certain cancers. It is essential for both genders to receive the vaccine to prevent the spread of HPV and its associated health risks.

5. The patient taking spironolactone (Aldactone) makes a statement indicating effective teaching. Which statement shows understanding of the teaching?

• A. I will use salt substitutes to lower my sodium intake
• B. I will increase my intake of foods that are high in potassium
• C. I will call my doctor if I begin having menstrual irregularities
• D. I will take this medication at bedtime each evening

Correct answer: C

Rationale: The correct answer is C because spironolactone is a potassium-sparing diuretic that can cause endocrine effects like menstrual irregularities. Therefore, the patient recognizing the need to report such changes indicates effective teaching. Choices A and B are incorrect as salt substitutes and high-potassium foods should be avoided with spironolactone. Choice D is also incorrect because diuretics, including spironolactone, are ideally taken in the morning to prevent disturbances in sleep due to nocturia.
