Assessment of Hematologic System NCLEX Questions Questions
Question 1 of 5
Which toy is the most developmentally appropriate for an 18- to 24-month-old child?
Correct Answer: A
Rationale: The correct answer is A: A push-and-pull toy. At 18-24 months, children are developing gross motor skills. Push-and-pull toys help strengthen muscles and improve coordination. They also encourage balance and enhance spatial awareness. Nesting blocks are more suitable for fine motor skills, while a bicycle with training wheels requires more advanced motor skills. A computer is not developmentally appropriate as young children need hands-on, physical play for optimal growth and learning.
Question 2 of 5
A cardiac defect that allows blood to shunt from the (high pressure) left side of the heart to the (lower pressure) right side can result in:
Correct Answer: B
Rationale: The correct answer is B: Congestive heart failure. A cardiac defect causing left-to-right shunting leads to increased blood volume in the right side of the heart, causing volume overload and eventually congestive heart failure. Cyanosis (choice A) occurs with right-to-left shunting, not left-to-right shunting. Decreased pulmonary blood flow (choice C) would be more likely with a defect causing right-to-left shunting. Bounding pulses in upper extremities (choice D) are not directly related to left-to-right shunting but can be seen in conditions like aortic regurgitation.
Question 3 of 5
Nursing care of the child with Kawasaki disease is challenging because of:
Correct Answer: A
Rationale: The correct answer is A because Kawasaki disease is characterized by high fever, irritability, and mucous membrane changes. The child's irritability can make nursing care challenging due to difficulties in assessing and managing their symptoms and needs effectively. The other choices are incorrect because: B - Kawasaki disease has an unpredictable course with potential complications; C - Antibiotics are not the primary treatment for Kawasaki disease; D - Requests for food are not typically a significant challenge in caring for a child with this condition. In summary, the correct answer highlights the primary symptom that can complicate nursing care, while the other choices are not directly related to the challenges of managing Kawasaki disease.
Question 4 of 5
Which of the following is not associated with mucosal surfaces?
Correct Answer: D
Rationale: The correct answer is D: white pulp. White pulp is a component of the spleen and is not directly associated with mucosal surfaces. Mucosal surfaces are lined with mucus-secreting goblet cells (A) that provide a protective barrier. Lysozyme (B) is an enzyme found in tears, saliva, and mucus that helps defend against bacterial infections on mucosal surfaces. M cells (C) are specialized cells in the mucosa-associated lymphoid tissue that transport antigens from the gut lumen to immune cells. In summary, white pulp is not part of mucosal surfaces, making it the correct answer.
Question 5 of 5
Immune cells within the lymphatic circulation are directly deposited into which of the following anatomical sites so that the cells may reenter the bloodstream?
Correct Answer: B
Rationale: Step-by-step rationale: 1. Immune cells exit lymphatic circulation via thoracic duct. 2. Thoracic duct empties into left subclavian vein. 3. Immune cells reenter bloodstream through left subclavian vein. 4. Therefore, B (left subclavian vein) is correct. Summary: A: The right aorta does not connect to lymphatic circulation. C: The left carotid artery carries blood to the brain, not lymph. D: High endothelial venule is within lymph nodes, not the bloodstream.
