Pediatric Nursing Practice Questions Questions
Question 1 of 5
Which neurotransmitter mediates the sympathetic response?
Correct Answer: A
Rationale: The sympathetic nervous system is responsible for our "fight or flight" response to stressful situations. Norepinephrine is the primary neurotransmitter that mediates the sympathetic response, acting on adrenergic receptors in various target tissues. It helps to increase heart rate, elevate blood pressure, dilate air passages in the lungs, and mobilize energy stores in the body to prepare for physical exertion or stress. Acetylcholine is another neurotransmitter involved in the sympathetic nervous system, but norepinephrine is the primary mediator of the fight or flight response.
Question 2 of 5
When performing a neurological examination on Mr. RR, which of the following would not be considered an important or useful part of the examination?
Correct Answer: D
Rationale: When performing a neurological examination on Mr. RR, pupil size due to neurologic medications would not typically be considered an important or useful part of the examination. While assessing pupil size and reactivity can provide valuable information about brain function and potential neurological issues, the focus of the initial examination would generally be on assessing eye movements, reflexes, and signs of nuchal rigidity. Pupil size related to medications would be more relevant in a medication review or history-taking rather than in the initial neurological examination.
Question 3 of 5
Which of the ff. statements does the nurse understand is true concerning air conduction of sound in the ear?
Correct Answer: B
Rationale: Air conduction of sound in the ear involves the transmission of sound waves through the air from the outer ear canal to the middle ear, where they cause the tympanic membrane (eardrum) to vibrate. These vibrations are then transmitted through the ossicles (tiny bones in the middle ear) to the inner ear, where they ultimately stimulate the hair cells in the cochlea to create the auditory nerve impulses. While air conduction is the most common method of sound transmission, it is less efficient than bone conduction. Bone conduction is the transmission of sound vibrations directly to the inner ear through the bones in the skull. This method bypasses the outer and middle ear and is often more efficient in conducting sound, especially at higher frequencies or in individuals with hearing loss related to the outer or middle ear.
Question 4 of 5
A client with a history of chronic hyperparathyroidism admits to being noncompliant. Based on initial assessment findings, the nurse formulates the nursing diagnosis of Risk for injury. To complete the nursing diagnosis statement for this client, which "related-to" phrase should the nurse add?
Correct Answer: A
Rationale: Chronic hyperparathyroidism can lead to excessive bone demineralization due to increased levels of parathyroid hormone. This can weaken the bones and increase the risk for pathologic fractures. Therefore, the most appropriate "related-to" phrase to add to the nursing diagnosis of Risk for injury for a client with chronic hyperparathyroidism would be bone demineralization resulting in pathologic fractures. This accurately reflects the potential risk for injury associated with the client's condition.
Question 5 of 5
Which nursing diagnosis takes highest priority for a client with hyperparathyroidism?
Correct Answer: B
Rationale: Among the listed nursing diagnoses, the highest priority for a client with hyperparathyroidism would be addressing the risk for impaired skin integrity. This is because hyperparathyroidism can lead to increased levels of calcium in the blood, which can result in skin issues such as edema (swelling), skin fragility, and poor wound healing. Addressing this risk is crucial to prevent skin breakdown, infections, and other complications associated with compromised skin integrity. Proper wound care, skin protection measures, and monitoring for any skin changes are essential in managing this priority nursing diagnosis for a client with hyperparathyroidism.
