Correct Answer: A

Rationale: A resting respiratory rate of 40 breaths per minute is within the expected range for a 3-year-old child. This is considered normal in this age group as their respiratory rate is generally higher compared to adults. Bronchovesicular breath sounds in the peripheral lung fields are not an expected finding in a 3-year-old. Retractions in the intercostal spaces with each inspiration indicate increased work of breathing and are abnormal. High-pitched whistling sounds over the bronchi are characteristic of wheezing, which is not typically expected in a healthy 3-year-old during a routine check-up.

Correct Answer: D

Rationale: The correct first action for the school nurse to take in this situation is to wash Child B's arm thoroughly with soap and water. Washing the wound immediately is crucial to reduce the risk of infection from the bite. Applying antibiotic cream may come after cleaning the wound. Determining Child A's medical history or checking Child B's tetanus status is important but not the immediate priority when dealing with a bite wound.

Correct Answer: A

Rationale: The correct answer is A because counseling will help the woman understand her risk and options for surveillance or preventive measures. At this point, it is crucial to address the woman's immediate concerns related to the BRCA1 gene mutation. Choice B is incorrect as the focus should be on the woman's individual risk due to the specific gene mutation she carries. Choice C is not the priority as treatment options come after assessing the risk and deciding on surveillance or preventive measures. Choice D is incorrect because discussing survival rates is not the immediate need for someone who has just received information about having a genetic mutation.

Correct Answer: C

Rationale: In this scenario, the priority action for the nurse is to send the client for a computed tomography (CT) scan of the brain. A CT scan is crucial in assessing acute changes or bleeding that could influence treatment decisions in a suspected cerebrovascular accident (CVA). While addressing symptoms like headache and nausea is important, ruling out acute changes in the brain with a CT scan takes precedence in this situation. Collecting blood for coagulation times may be necessary but is not the initial priority. Obtaining a history of medication use, recent surgery, or injury is also important but not the first action to take when a CVA is suspected.
