Correct Answer: C

Rationale: Implementing discipline and limit setting for infants and toddlers is primarily important as it provides them with a sense of security. This sense of security is crucial for their emotional and psychological development, helping them feel safe and supported as they explore the world around them. Choice A is incorrect because while developing social skills is important, the primary reason for discipline and limit setting in this context is to provide security. Choice B is incorrect as it does not address the main reason for implementing discipline and limit setting. Choice D is incorrect as the primary focus is not about dealing with authority at this early stage of development.

Correct Answer: C

Rationale: In the management of acute asthma exacerbations, the first-line medication for quick relief of bronchoconstriction is a short-acting beta agonist, such as albuterol. These medications help to rapidly open up the airways, providing immediate relief to the patient. Inhaled corticosteroids are more commonly used for long-term control of asthma symptoms, while oral corticosteroids and leukotriene receptor antagonists are often reserved for more severe or chronic cases. Therefore, in a child experiencing severe asthma symptoms, the practical nurse should anticipate the administration of short-acting beta agonists as the initial intervention to provide quick relief and improve breathing.

Correct Answer: A

Rationale: Keeping the infant away from people with colds is crucial to prevent the spread of respiratory infections, especially for infants recently hospitalized with bronchiolitis. This precaution helps protect the baby from further illnesses and promotes recovery. The other choices are incorrect because it is important to complete the prescribed medication course even if the baby seems better to ensure the infection is fully treated (Choice B). Solid foods are usually introduced around six months of age, so avoiding them entirely may not be necessary (Choice C). Placing the baby to sleep on their back is a safe sleep practice to prevent sudden infant death syndrome (SIDS) but may not directly help with breathing in the context of bronchiolitis (Choice D).

Correct Answer: A

Rationale: Obtaining a specimen for blood cultures is crucial in this situation as it helps identify the source of infection, if present, and guide appropriate treatment. This is important in a child with leukemia receiving chemotherapy to prevent potential complications and ensure timely intervention. Assessing the CBC may provide overall information on the child's condition but may not specifically identify a potential infection. Monitoring the oral temperature is important but obtaining blood cultures takes precedence in this scenario. Administering acetaminophen can help reduce fever but does not address the need to identify a possible infection source.

Correct Answer: B

Rationale: The correct answer is B: 'I will give my baby iron-fortified cereal.' Iron-fortified cereal is an excellent source of iron for infants, aiding in the prevention of iron deficiency anemia. Choice A is incorrect as whole cow's milk should not be introduced until the child is at least 12 months old to prevent iron deficiency. Choice C is incorrect because giving fruit juice between meals can interfere with iron absorption. Choice D is incorrect as giving water with meals can decrease nutrient intake. Therefore, the best choice to prevent iron deficiency anemia in a 9-month-old infant is to give them iron-fortified cereal.
