Nursing Elites

1. A healthcare professional is preparing to administer a measles, mumps, and rubella (MMR) vaccine to a 15-month-old child. Which of the following findings is a contraindication to the administration of this vaccine?

• A. Family history of egg allergy
• B. Currently taking antibiotics
• C. History of asthma
• D. Presence of rhinorrhea

Correct answer: B

Rationale: Taking antibiotics is a contraindication to receiving the MMR vaccine because antibiotics can potentially interfere with the effectiveness of the vaccine. It is essential to avoid administering the MMR vaccine while the child is on antibiotics to ensure the vaccine provides the intended protection.

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 parent of a child with cystic fibrosis is being taught about dietary guidelines. Which statement by the parent indicates an understanding of the teaching?

• A. My child should eat a high-calorie, high-protein diet.
• B. My child should avoid eating eggs.
• C. My child should follow a low-fat, low-sodium diet.
• D. My child should follow a high-fiber, high-protein diet.

Correct answer: A

Rationale: The correct answer is A. For a child with cystic fibrosis, a high-calorie, high-protein diet is recommended to meet the increased metabolic needs associated with the condition. The protein helps with growth and repair, while the extra calories help compensate for malabsorption and increased energy requirements. Choice B is incorrect because eggs are a good source of protein and essential nutrients unless the child has a specific allergy. Choice C is incorrect as a low-fat, low-sodium diet is not typically recommended for children with cystic fibrosis who need higher calorie and fat intake. Choice D is incorrect because while a high-protein diet is beneficial, a high-fiber diet may not be suitable for a child with cystic fibrosis due to potential gastrointestinal issues.

4. During an assessment, an infant is suspected to have intussusception. Which of the following findings should the nurse expect?

• A. Currant jelly stools
• B. Projectile vomiting
• C. Scaphoid abdomen
• D. Frequent stools

Correct answer: A

Rationale: Intussusception is a condition where one segment of the intestine telescopes into another, causing obstruction. The classic presentation includes currant jelly stools, which are a mixture of blood and mucus due to the sloughing of the intestinal mucosa. This finding is a result of the compromised blood supply to the affected area and is a key characteristic associated with intussusception.

5. A nurse is teaching a parent of a child who has asthma. Which of the following instructions should the nurse include?

• A. Use a peak flow meter daily.
• B. Administer the medication with meals.
• C. Provide a low-carbohydrate diet.
• D. Limit exposure to cold air.

Correct answer: A

Rationale: The nurse should instruct the parent to use a peak flow meter daily to monitor the child�s respiratory status and detect early signs of an asthma attack.
