A college health nurse interprets the peak expiratory flow rate for student who has asthma and finds that the student is in the yellow zone of his asthma action plan. The nurse should base her actions on which of the following information? (Select all that apply.)
The student's asthma is not well controlled.
The nurse should obtain a second expiratory flow rate.
The student needs to go to the hospital.
The student should use his quick-relief inhaler.
The student's peak flow is 50% to 80% of his best peak flow.
Correct Answer : A,D,E
A. The student's asthma is not well controlled: Being in the yellow zone indicates that the student's asthma is not well controlled and that their peak expiratory flow rate (PEFR) is lower than usual. This is a crucial point for the nurse to recognize, as it suggests that the student may need to adjust their management plan to prevent an exacerbation.
B. The nurse should obtain a second expiratory flow rate: While it can be helpful to reassess peak flow rates, it is not always necessary unless there is a concern about the accuracy of the initial measurement. The initial yellow zone result provides sufficient information for the nurse to take appropriate action regarding the student's asthma management.
C. The student needs to go to the hospital: Being in the yellow zone does not automatically require hospitalization. The yellow zone typically indicates that the student is experiencing some worsening of asthma symptoms but can often be managed at home with appropriate interventions. Hospitalization is usually reserved for the red zone, where severe symptoms or a significant decrease in peak flow occurs.
D. The student should use his quick-relief inhaler: This is an appropriate action for a student in the yellow zone. The yellow zone often indicates the need for the use of a quick-relief inhaler to alleviate symptoms and improve airflow. The nurse should advise the student to use their inhaler as per their asthma action plan.
E. The student's peak flow is 50% to 80% of his best peak flow: This statement accurately describes the yellow zone, where the peak flow is between 50% and 80% of the student's personal best. This information is essential for determining the appropriate response to the current asthma status and guides the nurse's actions.

Correct Answer is ["4"]
Explanation
Formula:
Volume to administer (mL) = (Desired dose (mg) / Available concentration (mg/mL))
Desired dose = 1.6 mg
Available concentration = 2 mg / 5 mL
Calculate the concentration per mL:
2 mg / 5 mL = 0.4 mg/mL
Volume to administer = 1.6 mg / 0.4 mg/mL
= 4 mL
The nurse should administer 4 mL per dose.
Correct Answer is B
Explanation
A. Poorly coordinated care and nosocomial infections are examples of errors: While poorly coordinated care can lead to adverse events, nosocomial infections are typically classified as healthcare-associated infections rather than errors. Errors generally refer to mistakes made in clinical practice that can lead to harm, whereas nosocomial infections are outcomes that arise from the healthcare environment.
B. As many as 90% of medication errors are preventable: This statement is true and highlights the significant opportunity for improvement in patient safety. Recognizing that a large percentage of medication errors can be prevented underscores the importance of implementing safety protocols, effective communication, and education to reduce the likelihood of errors occurring in clinical practice.
C. Errors of execution are usually intentional and occur because of time or resource constraints: This statement is misleading, as errors of execution typically refer to mistakes made during the performance of a task rather than intentional actions. These errors often occur due to lack of knowledge, skill, or attention rather than being intentional, and they are not solely attributed to time or resource constraints.
D. Medication errors are adverse events: While medication errors can lead to adverse events, not all medication errors result in harm. An adverse event is defined as an injury caused by medical management rather than the underlying condition of the patient, so this statement is not entirely accurate. Medication errors can be classified as near misses or adverse events, depending on whether they resulted in harm to the patient.
