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

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. A nurse is teaching a newly licensed nurse about ergonomic principles. Which of the following actions by the newly licensed nurse indicates an understanding of the teaching?

Correct answer: C

Rationale: The correct answer is C because using a mechanical lift is an ergonomic practice that ensures safe body mechanics and prevents injuries. Choice A is incorrect as standing with feet together when lifting a client does not promote proper body mechanics. Choice B is incorrect as raising the client's head of bed before pulling the client up is not directly related to ergonomic principles. Choice D is incorrect as placing a gait belt around the client's upper chest is a safety measure for assisting with standing but does not address ergonomic principles.

3. What is the most appropriate action when a patient experiences chest pain?

Correct answer: A

Rationale: Administering aspirin is the correct initial action when a patient experiences chest pain. Aspirin helps reduce the risk of clot formation and is a standard first-line treatment for chest pain related to possible cardiac issues. Administering nitroglycerin may be appropriate based on the underlying cause of chest pain, but aspirin is typically administered first. Repositioning the patient is not the primary intervention for chest pain, and preparing for surgery is not the immediate action required unless indicated by a healthcare provider after assessment.

4. Following a spinal cord injury suffered in a motor vehicle accident, a 22-year-old male has lost fine motor function of his finger and thumb, but is still able to perform gross motor movements of his hand and arm. Which component of his 'white matter' has most likely been damaged?

Correct answer: C

Rationale: The correct answer is C: The outer layer (neolayer). The white matter of the spinal cord consists of three layers: the outer layer (neolayer), the middle layer (paleolayer), and the inner layer (archilayer). Damage to the outer layer (neolayer) is likely to affect fine motor skills, explaining the loss of fine motor function in the finger and thumb while gross motor movements remain intact. Choices A, B, and D are incorrect as they do not correspond to the specific layer of the white matter that is typically associated with fine motor control.

5. A healthcare provider is assessing a client who had a myocardial infarction. Upon auscultating heart sounds, the provider hears the following sound. What action by the provider is most appropriate?

Correct answer: A

Rationale: The sound described is an S3 heart sound, which can indicate heart failure. The next appropriate action for the provider is to listen to the client's lung sounds. Lung sounds can provide additional information about the client's condition, especially when abnormal heart sounds are present. Calling the Rapid Response Team is not warranted based solely on the heart sound assessment. Having the client sit upright is not directly related to addressing the abnormal heart sound.
