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. What is an essential nursing care intervention for a neonate with a suspected tracheoesophageal fistula?

• A. Feed glucose water only.
• B. Elevate the patient's head for feedings.
• C. Raise the patient's head and give nothing by mouth.
• D. Avoid suctioning unless the infant is cyanotic.

Correct answer: C

Rationale: Raising the patient’s head and giving nothing by mouth is crucial in managing tracheoesophageal fistula. This intervention helps prevent aspiration and further complications until surgical correction can be performed. Feeding the neonate or suctioning could exacerbate the condition by risking aspiration. Elevating the head for feedings does not address the primary concern of preventing oral intake, making it less appropriate than the correct answer.

3. The nurse is performing an oral examination on a preschool child. Which strategies should the nurse use to encourage the child to open the mouth for the examination? (Select all that apply.)

• A. Lightly brush the palate with a cotton swab
• B. Perform the examination in front of a mirror
• C. Let the child examine someone else's mouth first
• D. All of the above

Correct answer: D

Rationale: Using a cotton swab, allowing the child to observe, and demonstrating on someone else are effective ways to encourage a preschooler to open their mouth for examination.

4. The nurse is evaluating research studies according to the GRADE criteria and has determined the quality of evidence on the subject is moderate. Which type of evidence does this determination indicate?

• A. Strong evidence from unbiased observational studies
• B. Evidence from randomized clinical trials showed inconsistent results
• C. Consistent evidence from well-performed randomized clinical trials
• D. Evidence for at least one critical outcome from randomized clinical trials had serious flaws

Correct answer: B

Rationale: Moderate evidence typically indicates that results from randomized clinical trials were inconsistent, highlighting the need for further research to confirm findings.

5. Which drug is usually the best choice for patient-controlled analgesia (PCA) for a child in the immediate postoperative period?

• A. Codeine sulfate (Codeine)
• B. Morphine (Roxanol)
• C. Methadone (Dolophine)
• D. Meperidine (Demerol)

Correct answer: B

Rationale: Morphine is the drug of choice for PCA in children because of its efficacy, safety profile, and rapid onset of action for pain management.
