The school nurse is teaching the faculty the most effective methods to prevent the spread of lice in the school. The information that would be most important to include would be which of these statements?

Correct Answer: C

Rationale: The most crucial information to prevent the spread of lice in schools is to avoid sharing hats, scarves, and combs. This is important as lice can easily spread through shared personal items. Choices A, B, and D are not as critical as choice C in preventing the spread of lice. Reapplication of treatment, boiling or steaming bedding and clothing, and using nit combs are important but not as crucial as avoiding the sharing of personal items.

Correct Answer: B

Rationale: The correct answer is B, Chvostek's sign. This is a classic sign of hypocalcemia, which can occur after a thyroidectomy due to injury or removal of the parathyroid glands. Hypocalcemia can lead to serious complications like tetany and laryngospasm, necessitating immediate attention. Assessing Chvostek's sign helps in early identification and management of hypocalcemia. Choices A, C, and D are not the priority in this situation. While assessing the calcium level is important for diagnosing hypocalcemia, the immediate concern is to identify clinical signs like Chvostek's sign, which indicate acute hypocalcemia. Trousseau's sign is also related to hypocalcemia but is not the most critical sign to assess first. Serum potassium level, although important for overall electrolyte balance, is not directly related to the client's current symptoms of tingling in the fingers and around the mouth.

Correct Answer: A

Rationale: Auscultation of breath sounds is the highest priority assessment in a client with a history of asthma experiencing difficulty breathing. It helps the nurse evaluate the severity of the asthma exacerbation by listening for wheezing, crackles, or decreased breath sounds. This assessment guides treatment decisions, such as administering bronchodilators or oxygen therapy. Measurement of peak expiratory flow, although important in assessing asthma severity, may not be feasible in an emergency situation where immediate intervention is needed. Observation of accessory muscle use and assessment of skin color are also important assessments in asthma exacerbation, but auscultation of breath sounds takes precedence in determining the need for urgent interventions.

Correct Answer: D

Rationale: The correct answer is to check the client's oxygen saturation level first. This action is crucial in assessing the severity of dyspnea and determining the necessity for oxygen therapy. Administering oxygen therapy without knowing the current oxygen saturation level can be inappropriate and potentially harmful. Encouraging deep breathing exercises and raising the head of the bed are important interventions, but assessing the oxygen saturation level takes precedence in managing dyspnea in a client with COPD.

Correct Answer: C

Rationale: When a client is receiving intravenous antibiotics, checking the IV site for signs of phlebitis is a priority assessment for the nurse. Phlebitis is an inflammation of the vein, which can lead to serious complications such as infection and thrombosis. Monitoring the IV site helps prevent these complications and ensures the safe delivery of antibiotics. While monitoring the client's temperature, pain level, and respiratory status are important assessments, they are not the priority in this scenario where IV antibiotic administration requires close monitoring for complications like phlebitis.
