Pediatric HESI Test Bank Questions
Question 1 of 5
is X linked recessive disorder :
Correct Answer: B
Rationale: Hemophilia is an X-linked recessive disorder where the genes responsible for blood clotting factors are located on the X chromosome. This disorder primarily affects males, as they have only one X chromosome. Females are carriers and can pass the gene on to their sons. Hemophilia results in prolonged bleeding episodes as the blood is unable to clot properly. Thalassemia, leukemia, and sickle cell anemia are not X-linked disorders. Digoxin is a medication used for heart conditions, not related to X-linked disorders.
Question 2 of 5
The nurse is presenting an in-service session on assessing gestational age in newborns. Which information should be included?
Correct Answer: C
Rationale: The newborn's posture at rest and arm recoil are two physical signs used to determine gestational age. Assessment of posture at rest involves observing the newborn's flexed or extended posture when lying flat on their back. Premature infants tend to have more flexed postures due to their immature muscular tone. Arm recoil refers to the ability of the newborn to return their extended arm flexes to the flexed position. This reflex is typically present in more mature infants. These physical signs, along with other factors such as skin texture, breast development, and ear formation, are used by healthcare providers to estimate the gestational age of newborns. While length, weight, and head circumference are also important measurements, the posture at rest and arm recoil are specifically used in determining gestational age.
Question 3 of 5
Parents of a newborn ask the nurse why vitamin K is being administered. The nurse accurately responds by explaining phytonadione (vitamin K) is administered to the newborn to:
Correct Answer: A
Rationale: Vitamin K is essential for the production of clotting factors in the liver. Newborns have lower levels of vitamin K and may not have a fully functioning clotting system, putting them at risk for bleeding disorders such as vitamin K deficiency bleeding (VKDB). Administering vitamin K to newborns helps prevent these bleeding issues and ensures proper clotting function. It does not have a direct effect on enhancing the immune response, preventing bacterial infections, or maintaining nutritional status, as its primary function in this context is to prevent bleeding disorders.
Question 4 of 5
Which nursing consideration is important when caring for a child with impetigo contagiosa?
Correct Answer: C
Rationale: Carefully washing hands and maintaining cleanliness when caring for an infected child with impetigo contagiosa is important due to its highly contagious nature. Impetigo is a skin infection that is easily spread through direct contact with the lesions or with items contaminated by the infected person such as towels, clothing, or bedding. By washing hands and maintaining cleanliness, caregivers can help prevent the spread of infection to others and minimize the risk of re-infection to the child. This nursing consideration is crucial in managing impetigo and promoting the child's recovery.
Question 5 of 5
Which may be given to high-risk children after exposure to chickenpox to prevent varicella?
Correct Answer: D
Rationale: VCZ immune globulin (VariZIG) is given to high-risk children after exposure to chickenpox to prevent varicella. VariZIG contains antibodies against the varicella-zoster virus, providing passive immunity to the child. This can help reduce the severity of the infection or prevent it altogether in high-risk individuals. Acyclovir (Zovirax) is an antiviral medication used to treat varicella infections but is not typically used for prevention post-exposure. Varicella globulin is not a treatment for varicella. Diphenhydramine hydrochloride (Benadryl) is an antihistamine and is not used for preventing varicella post-exposure.
