Pediatric Nursing Practice Questions Questions
Question 1 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 2 of 5
What is the best description of anorexia nervosa?
Correct Answer: D
Rationale: Anorexia nervosa is a serious eating disorder characterized by a persistent restriction of food intake, leading to significantly low body weight. Individuals with anorexia have an intense fear of gaining weight or becoming fat, despite being underweight. The disorder results in severe weight loss due to excessive dieting, exercising, or other behaviors to control weight. It is not caused by a posterior pituitary disorder, nor is it limited to a specific gender or socioeconomic group.
Question 3 of 5
All the following are characteristic of retinal hemorrhage caused by abusive head trauma (AHT) EXCEPT
Correct Answer: D
Rationale: Traumatic retinoschisis is not typically associated with AHT-related retinal hemorrhages. Characteristics such as multiple layers, central location, and varying sizes are hallmarks of AHT-induced retinal damage.
Question 4 of 5
An adolescent has been diagnosed with Chlamydia infection. Which medication should the nurse expect to be prescribed for this condition?
Correct Answer: B
Rationale: Chlamydia infection is commonly treated with antibiotics, such as azithromycin or doxycycline. Azithromycin is often preferred due to its convenience of a single oral dose. It is effective in treating Chlamydia infections in both adolescents and adults. Ceftriaxone, penicillin G benzathine, and acyclovir are used to treat different types of infections and are not appropriate choices for Chlamydia infection.
Question 5 of 5
The nurse notes frequent muscle twitching when collecting admission data on a patient admitted for increasing muscle weakness. Which of the ff. terms should the nurse use to document this?
Correct Answer: A
Rationale: Fasciculations are small, involuntary muscle contractions or twitching observed under the skin. In this scenario, the nurse noted frequent muscle twitching in the patient, which aligns with the characteristic manifestation of fasciculations. It is important for the nurse to accurately document this observation as it can provide valuable information to the healthcare team in assessing the patient's condition and determining the underlying cause of the muscle weakness. Chorea refers to irregular, rapid, and jerky movements that are not present in this case. Atrophy indicates muscle wasting, while neuropathy involves damage or dysfunction of nerves, neither of which specifically describes the observed muscle twitching.
