While eating in the hospital cafeteria, a nurse notices a toddler at a nearby table choking on a piece of food and appearing slightly blue. What is the appropriate initial action to take?

Correct Answer: C

Rationale: When a toddler is choking on a piece of food and appears blue, it indicates airway obstruction. The appropriate initial action should be to perform 5 abdominal thrusts. This technique can help dislodge the obstructing object and clear the airway. Initiating mouth-to-mouth resuscitation is not recommended as the first step in a choking emergency, especially in children. Giving water may not be effective and can worsen the situation by causing further blockage. Calling the emergency response team should be considered if the abdominal thrusts are unsuccessful in clearing the airway.

Correct Answer: A

Rationale: The correct answer is 'Cereal.' The guidelines of the American Academy of Pediatrics recommend introducing one new food at a time, starting with strained cereal. Cereal is often recommended as a first solid food for infants due to its soft texture and iron-fortified properties, which are important for the baby's development. Eggs and meat are common allergenic foods and are usually introduced later. Juice is not recommended for infants under 1 year old due to its high sugar content and lack of nutritional value compared to whole fruits.

Correct Answer: C

Rationale: The correct answer is self-blame. In this scenario, the victim is attributing the abuse to their own inadequacies or faults, thinking that if they were different, the abuse would not occur. This is a common response seen in victims of domestic violence, where they wrongly internalize the blame for the abuser's actions. Fear (Choice A) is a valid emotion, but in this case, the victim is not expressing fear but rather self-blame. Helplessness (Choice B) is also a common feeling in victims of domestic violence, but in this specific statement, the victim is demonstrating self-blame. Rejection (Choice D) does not accurately reflect the victim's statement and emotional response in the given scenario.

Correct Answer: B

Rationale: The correct answer is to ask the client to perform a calculation that involves working memory and processing skills. This question not only assesses the recent memory but also evaluates attention and executive functioning. The choice 'I am going to say the names of three things, and I want you to repeat them after me: blue, ball, pen' assesses immediate recall rather than recent memory. Asking about the current year or season tests orientation rather than recent memory. Inquiring about the watch and its purpose assesses comprehension and judgment rather than recent memory.

Correct Answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.
