The nurse is admitting a child with severe isotonic dehydration. Which intravenous fluid should the nurse anticipate the doctor to order initially to replace fluids?
- A. 0.9% normal saline
- B. D5 0.2% (1/4) normal saline
- C. D5W
- D. Albumin
Correct Answer: A
Rationale: In the case of severe isotonic dehydration, the initial fluid of choice is 0.9% normal saline. This solution is preferred because it helps to restore both fluids and electrolytes effectively. Options B, C, and D are not suitable for the initial management of severe isotonic dehydration. D5 0.2% (1/4) normal saline (Choice B) is a hypotonic solution and might worsen the imbalance. D5W (Choice C) is a hypotonic solution that does not contain electrolytes essential for rehydration. Albumin (Choice D) is a colloid solution used for specific indications like hypoproteinemia or hypoalbuminemia, not for initial rehydration in severe dehydration.
Where would nonpathologic cyanosis normally be present in the newborn shortly after birth?
- A. Feet and hands
- B. Bridge of nose
- C. Circumoral area
- D. Mucous membranes
Correct Answer: A
Rationale: Nonpathologic cyanosis in newborns shortly after birth is typically present in the feet and hands, known as acrocyanosis. This is a normal finding due to the immature peripheral circulation in newborns. Cyanosis of the bridge of the nose, circumoral area, and mucous membranes indicates generalized cyanosis, which suggests a potential underlying distress or major abnormality. Therefore, choice A is correct as it describes the expected location for nonpathologic cyanosis in newborns, while choices B, C, and D represent areas associated with abnormal cyanosis.
Several types of long-term central venous access devices are used. What is a benefit of using an implanted port (e.g., Port-a-Cath)?
- A. You do not need to pierce the skin for access.
- B. It is easy to use for self-administered infusions.
- C. The patient does not need to limit regular physical activity, including swimming.
- D. The catheter cannot dislodge from the port even if the child plays with the port site.
Correct Answer: C

The nurse on a pediatric unit is writing guidelines for age-specific preparation of children for procedures based on developmental characteristics. What guideline is accurate?
- A. Inform toddlers about an upcoming procedure 2 hours before the procedure is to be performed.
- B. Inform school-age children about an upcoming procedure immediately before the procedure is scheduled to occur.
- C. Discourage parent presence during procedures on infants and toddlers.
- D. Use simple diagrams of anatomy and physiology to explain a procedure to a school-age child.
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Chemicals, agents, or factors that cause physical defects in the developing embryo and are most harmful during organogenesis are:
- A. Teratogens
- B. Heterozygous
- C. Inborn errors
- D. Multifactorial
Correct Answer: A
Rationale: Teratogens are substances that can cause congenital abnormalities, especially during the first trimester when organogenesis occurs. Choice A, Teratogens, is the correct answer as it specifically refers to substances that cause physical defects in the developing embryo. Choices B, Heterozygous, C, Inborn errors, and D, Multifactorial, are incorrect as they do not directly relate to substances that cause physical defects in embryos during organogenesis.
