1. At what age does a 9-year-old child typically lose which of the following teeth?

Correct answer: A

Rationale: A 9-year-old child typically loses their central incisors, not the lateral incisors or second molars. The central incisors are usually among the first teeth that children lose around 6 to 7 years of age, as part of the natural process of shedding primary teeth to make way for permanent teeth. The second molars and cuspids are typically lost later in the mixed dentition phase. Therefore, option A, 'Central incisor,' is the correct answer.

2. The PN assigns a UAP to assist with the personal care of a client experiencing an acute exacerbation of multiple sclerosis. Which instruction should the PN provide the UAP?

Correct answer: B

Rationale: During an acute exacerbation of multiple sclerosis, it is important to encourage self-care to maintain the client's independence. Allowing rest periods helps prevent fatigue, which is crucial in managing MS exacerbations. Choice A is incorrect as hot baths can exacerbate symptoms in MS. Choice C is about communication techniques and not directly related to client care during an exacerbation. Choice D is not a priority intervention during an MS exacerbation.

3. During a blood transfusion, which sign or symptom should prompt the healthcare provider to immediately stop the transfusion?

Correct answer: B

Rationale: The correct answer is B: Elevated temperature and chills. These symptoms are indicative of a transfusion reaction, which can be severe and life-threatening. It is crucial to stop the transfusion immediately and notify the healthcare provider for further assessment and management. Elevated temperature and chills are classic signs of a transfusion reaction, specifically indicating a possible febrile non-hemolytic reaction. Choice A, a slight increase in blood pressure, is not typically a reason to stop a transfusion unless it is a significant sudden increase. Mild nausea (Choice C) and a slight headache (Choice D) are common side effects of blood transfusions and are not primary indicators of a transfusion reaction that require immediate cessation of the transfusion.

4. A post-operative client develops a sudden onset of chest pain and dyspnea. The nurse suspects a pulmonary embolism (PE). What is the priority nursing action?

Correct answer: A

Rationale: Administering oxygen via face mask is the priority nursing action in a post-operative client suspected of a pulmonary embolism. This intervention helps ensure adequate oxygenation while further assessments and interventions are initiated. Elevating the client's legs is not indicated for a suspected pulmonary embolism; it is more appropriate for conditions like shock. Immediate surgery is not the priority in this situation as the client is experiencing acute symptoms requiring prompt intervention. While notifying the healthcare provider is important, the immediate focus should be on providing oxygen to the client to support respiratory function.

5. Which hormone is primarily responsible for the regulation of calcium and phosphate in the blood?

Correct answer: A

Rationale: Parathyroid hormone is the correct answer. It regulates calcium and phosphate levels in the blood by increasing calcium reabsorption in the kidneys and releasing calcium from bones. Insulin is involved in glucose metabolism, not calcium and phosphate regulation. Cortisol is a stress hormone and is not primarily responsible for regulating calcium and phosphate levels. Thyroxine is a thyroid hormone that primarily regulates metabolism, not calcium and phosphate in the blood.
