Nursing Elites

1. Which heart sound is produced by vibrations within the heart chambers or in the major arteries from the back-and-forth flow of blood?

• A. S1 and S2
• B. S3 and S4
• C. Murmur
• D. Physiologic splitting

Correct answer: C

Rationale: A murmur is produced by turbulent blood flow within the heart or major arteries, resulting in audible vibrations.

2. An appropriate method for administering oral medications that are bitter to an infant or small child should be to mix them with which?

• A. Bottle of formula or milk
• B. Any food the child is going to eat
• C. One teaspoon of something sweet-tasting such as jam
• D. Carbonated beverage, which is then poured over crushed ice

Correct answer: C

Rationale: Mixing bitter medication with a small amount of something sweet, like jam, can mask the taste effectively without diluting the medication too much. Mixing with milk or formula is not recommended as the child may refuse future feedings, and carbonated beverages are not suitable for infants.

3. The parents of a school-age child ask the nurse if she thinks that their child has attention deficit hyperactivity disorder (ADHD). Which statement regarding the child’s behavior at school is most indicative of ADHD?

• A. He finishes his work on time in order to go to recess.
• B. He occasionally gets into trouble for talking.
• C. He enjoys math but does not like reading.
• D. He cannot sit still in his seat and constantly moves his legs.

Correct answer: D

Rationale: The most indicative behavior of ADHD is the inability to sit still and constant movement, known as hyperactivity. This behavior is a hallmark symptom of ADHD, making option D the correct choice. Options A, B, and C do not specifically reflect the characteristic hyperactivity associated with ADHD, making them less indicative of the disorder. While option B suggests impulsivity, it is not as specific to ADHD as the hyperactivity described in option D.

4. A 10-month-old infant is diagnosed with gastroesophageal reflux. An esophageal (pH) probe monitor is ordered. What explanation for the purpose of the esophageal probe should the nurse provide to the parents?

• A. Assist in the passage of formula through the esophagus
• B. Identify the number of reflux episodes that are occurring
• C. Determine the time it takes for the stomach to empty its contents
• D. Monitor the pH within the stomach

Correct answer: B

Rationale: The correct answer is B. The esophageal pH probe is used to identify the frequency and severity of reflux episodes by measuring the pH in the esophagus. Choice A is incorrect because the probe does not assist in the passage of formula through the esophagus. Choice C is incorrect as determining the time it takes for the stomach to empty its contents would require a different procedure. Choice D is incorrect as the esophageal pH probe monitors the pH in the esophagus, not the stomach.

5. When taking a child’s blood pressure, what percentage of the upper arm should the nurse ensure the cuff bladder width covers?

• A. 20%
• B. 40%
• C. 60%
• D. 80%

Correct answer: B

Rationale: When taking a child's blood pressure, the nurse should select a cuff with a bladder width that covers 40% of the arm circumference at the midpoint of the upper arm. This ensures accurate readings. Choosing a cuff that covers less or more than 40% can lead to incorrect blood pressure measurements. Therefore, options A, C, and D are incorrect.
