The mother of a 14-month-old child is concerned because the child’s appetite has decreased. The best response for the nurse to make to the mother is:

Correct Answer: B

Rationale: The correct answer is B: It is not unusual for toddlers to eat less. Toddlers often go through phases where their appetites fluctuate, and it is normal for them to eat less at times. This response reassures the mother that her child's decreased appetite is a common phenomenon among toddlers and typically not a cause for concern. Rationale: - A (It is important for your toddler to eat three meals a day and nothing in between): This answer is too rigid and may cause unnecessary stress for the mother. Toddlers may have varying eating patterns, and forcing them to adhere to a strict meal schedule can be counterproductive. - C (Be sure to increase your child’s milk consumption, which will improve nutrition): Increasing milk consumption may not necessarily improve nutrition and could lead to other issues such as iron deficiency. It is important to focus on a balanced diet rather than solely relying on milk. - D (Giving your child a multivitamin supplement daily will increase your toddler’s

Correct Answer: D

Rationale: The correct answer is D: Place child in the knee-chest position. This is the first action to relieve hypercyanotic spells in infants with Tetralogy of Fallot. Placing the child in the knee-chest position increases systemic vascular resistance, reduces venous return to the heart, and improves pulmonary blood flow. This helps alleviate the cyanosis by decreasing the right-to-left shunting of blood. Assessing for neurologic defects (A) is not the priority in this situation. Preparing the family for imminent death (B) is premature and not appropriate as the first action. Beginning cardiopulmonary resuscitation (C) is not indicated unless the infant becomes unresponsive.

Correct Answer: D

Rationale: The correct answer is D because therapeutic management of Kawasaki disease includes administration of gamma globulin to reduce the risk of coronary artery abnormalities and salicylates for anti-inflammatory effects. A is incorrect because aspirin is actually indicated for Kawasaki disease. B is incorrect as the principal area of involvement is the coronary arteries, not the joints. C is incorrect because Kawasaki disease is not responsive to antibiotics as it is an autoimmune disease.

Correct Answer: D

Rationale: The correct answer is D because all bacteria, viruses, and fungi are examples of pathogens that can cause human disease. Bacteria (choice A) such as Streptococcus and Staphylococcus can lead to infections like pneumonia and meningitis. Viruses (choice B) like Influenza and HIV cause illnesses such as the flu and AIDS. Fungi (choice C) such as Candida can result in fungal infections like yeast infections. Therefore, the correct answer includes all possible types of pathogens that can harm human health.

Correct Answer: C

Rationale: The correct answer is C because the flow of lymph through a lymph node draining an infected tissue follows this pathway: afferent lymphatic vessel (brings lymph into the node) → lymph node (where lymph is filtered) → efferent lymphatic vessel (carries filtered lymph out of the node). This sequence ensures that lymph containing pathogens or antigens from the infected tissue enters the lymph node for immune response activation and filtering before being circulated back into the bloodstream. Choice A is incorrect because it reverses the order of the lymphatic vessels, leading to the lymph node first and then out of the node. Choice B is incorrect because it introduces a venule before the lymph node, which is not part of the typical lymphatic pathway. Choice D is incorrect because it introduces an artery before the lymph node, which is not part of the lymphatic circulation pathway.
