1. Which parental statement indicates correct understanding of preventive techniques for heat-related illnesses when children exercise?

• A. Wearing dark clothing during exercise is not recommended.
• B. Water is the preferred fluid for fluid replenishment.
• C. During activity, stopping for fluids every 15 to 20 minutes is essential.
• D. Hydration should be maintained throughout the exercise session.

Correct answer: C

Rationale: The correct preventive technique for heat-related illnesses during exercise is to stop for fluids every 15 to 20 minutes to prevent dehydration and maintain hydration levels. This practice helps regulate body temperature and prevent heat-related complications. Choice A is incorrect as wearing light-colored, loose-fitting clothing is recommended to reflect sunlight and allow better air circulation. Choice B is incorrect as while water is important, a sports drink containing electrolytes may be more beneficial for longer exercise sessions. Choice D is incorrect as it does not emphasize the importance of regular fluid intake during exercise to prevent dehydration.

2. 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.

3. A nurse assesses a male patient who has developed gynecomastia while receiving treatment for peptic ulcers. Which medication from the patient�s history should the nurse recognize as a contributing factor?

• A. Amoxicillin (Amoxil)
• B. Cimetidine (Tagamet)
• C. Metronidazole (Flagyl)
• D. Omeprazole (Prilosec)

Correct answer: B

Rationale: Cimetidine binds to androgen receptors, producing receptor blockade, which can cause enlarged breast tissue, reduced libido, and impotence. All these effects reverse when dosing stops. Amoxicillin, metronidazole, and omeprazole are not associated with gynecomastia.

4. During a vaso-occlusive crisis in sickle cell anemia, what action is crucial for a nurse to take?

• A. Administer meperidine for pain.
• B. Apply cold compresses to the child's joints.
• C. Limit the child's fluid intake.
• D. Maintain bed rest for the child.

Correct answer: D

Rationale: During a vaso-occlusive crisis in sickle cell anemia, maintaining bed rest is crucial to reduce oxygen consumption and alleviate pain. Movement can worsen the crisis by increasing sickling of red blood cells, leading to further tissue damage and pain. Bed rest helps to improve blood flow, reduce pain, and promote healing. Administering meperidine for pain (Choice A) is not recommended due to the risk of normeperidine accumulation and potential neurotoxicity. Applying cold compresses (Choice B) may cause vasoconstriction, worsening the vaso-occlusive crisis. Limiting fluid intake (Choice C) is not appropriate as adequate hydration is essential to prevent dehydration and maintain blood flow.

5. Before administering a live virus vaccine to a patient taking a glucocorticoid medication, what action should the nurse take?

• A. Continue screening and administer the vaccine if appropriate
• B. Note the contraindication but administer the vaccine regardless
• C. Note the contraindication and clarify the order with the healthcare provider
• D. Withhold the vaccine and inform the department of health

Correct answer: C

Rationale: The correct action for the nurse to take when a patient on glucocorticoid medication is to note the contraindication and clarify the order with the healthcare provider. Glucocorticoids can suppress the immune response, potentially reducing the effectiveness of vaccines. Therefore, it is crucial to consult with the healthcare provider to assess the risks and benefits of administering a live virus vaccine in such circumstances. Administering a live virus vaccine to a patient taking glucocorticoids can increase the risk of developing a viral infection, making it essential to seek guidance from the healthcare provider before proceeding.
