Nursing Elites

1. Which reflex is expected to disappear by 4 months of age?

• A. Rooting reflex
• B. Moro reflex
• C. Babinski reflex
• D. Palmar grasp

Correct answer: B

Rationale: The Moro reflex, also known as the startle reflex, typically disappears by 4 months as the infant's nervous system matures. This reflex is important for assessing the development of the nervous system in newborns. The Rooting reflex (Choice A) is related to turning the head in response to cheek stimulation; the Babinski reflex (Choice C) involves the fanning of toes in response to foot stimulation; and the Palmar grasp (Choice D) is the curling of the fingers around an object placed in the infant's hand. These reflexes have different timelines for disappearance and are not typically expected to be gone by 4 months of age.

2. The charge nurse in the pediatric unit is teaching nursing students about pyloric stenosis. A student asks what causes pyloric stenosis. How should the nurse respond?

• A. One portion of the intestines invaginates or telescopes into another
• B. Hypertrophy of the circular pylorus muscle
• C. Relaxed cardiac sphincter
• D. Absent ganglion cells in the colon

Correct answer: B

Rationale: Pyloric stenosis is caused by the hypertrophy (thickening) of the circular muscle of the pylorus, leading to obstruction. Choice A is incorrect as it describes intussusception, not pyloric stenosis. Choice C is incorrect as a relaxed cardiac sphincter is related to gastroesophageal reflux. Choice D is incorrect as it describes Hirschsprung's disease, not pyloric stenosis.

3. The nurse is caring for a child receiving chemotherapy with the following orders: Zantac 70 mg IV in normal saline 30 mL to infuse over 30 minutes. The nurse should set the infusion pump to deliver how many mL/hour?

• A. 60 mL/hour
• B. 45 mL/hour
• C. 30 mL/hour
• D. 15 mL/hour

Correct answer: A

Rationale: The correct answer is A: 60 mL/hour. The total volume to be infused is 30 mL over 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume by the total time in hours. In this case, 30 mL / 0.5 hours = 60 mL/hour. Choice B, 45 mL/hour, is incorrect as it does not correspond to the calculated infusion rate. Choices C and D, 30 mL/hour and 15 mL/hour respectively, are also incorrect based on the calculation.

4. The nurse is describing clinical reasoning to a group of nursing students. Which is most descriptive of clinical reasoning?

• A. Purposeful and goal-directed
• B. A simple developmental process
• C. Based on deliberate and irrational thought
• D. Assists individuals in guessing what is most appropriate

Correct answer: A

Rationale: Clinical reasoning is purposeful and goal-directed, involving the use of critical thinking and decision-making skills to provide effective patient care.

5. Which medication should the nurse expect to administer to a child with an acute sickle cell pain crisis?

• A. Meperidine (Demerol)
• B. Morphine
• C. Acetaminophen (Tylenol)
• D. Ibuprofen (Motrin)

Correct answer: B

Rationale: In the management of acute sickle cell pain crisis in children, morphine is the preferred medication due to its effectiveness in providing pain relief. Meperidine (Demerol) is less commonly used in this scenario because of its potential for neurotoxicity with repeated doses. Acetaminophen (Tylenol) and Ibuprofen (Motrin) are not typically sufficient for managing the severe pain associated with sickle cell crises and are not the first-line treatment options.
