A nurse is preparing to administer 50 mcg of fentanyl to a client who is in labor. The amount available is 100 mcg per 2 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Health department data and statistics reports: Local or state health departments routinely collect and publish epidemiological data, including incidence and prevalence rates of communicable diseases like tuberculosis. These reports provide reliable, up-to-date statistics that are essential for planning and evaluating public health programs.

B. Expert opinion from local health care providers: Expert opinion can provide insights into trends or clinical observations, but it is anecdotal and not sufficient for calculating incidence rates. Public health planning requires data that is systematically collected and analyzed.

C. Browsing an internet search engine: While internet searches may yield general information, the results may not be accurate, up-to-date, or specific to the local population. Official health department sources are more reliable for incidence data.

D. Clinical guidelines from a professional organization: Clinical guidelines provide recommendations for diagnosis, treatment, and management, but they do not usually include local incidence statistics. They are not a primary source for epidemiological data.

A. Prepare for chest tube placement: Chest tube placement is indicated for conditions like pneumothorax or pleural effusion, which are not clearly present in this scenario. Immediate interventions should focus on stabilizing the client and evaluating cardiopulmonary status first.

B. Ensure that the client has venous access: Establishing IV access is essential for rapid administration of medications, fluids, or emergency interventions if the client’s condition deteriorates. This is a priority in acute postoperative complications.

C. Place the client in High Fowler's position: Elevating the head of the bed improves lung expansion, reduces dyspnea, and enhances oxygenation in a client experiencing sudden respiratory distress and crackles, which may indicate pulmonary edema or fluid overload.

D. Activate the rapid response team: The client exhibits acute respiratory distress, hypoxemia, tachypnea, and cardiovascular changes. Activating the rapid response team ensures timely advanced intervention and evaluation to prevent further deterioration.

E. Administer fondaparinux as prescribed: Postoperative clients following total hip arthroplasty are at high risk for venous thromboembolism. Administering anticoagulant therapy, such as fondaparinux, helps prevent pulmonary embolism, which could be causing the client’s sudden dyspnea.

F. Administer midazolam as prescribed: Midazolam is a sedative and would not address the client’s acute respiratory distress. Sedation could worsen hypoxemia and respiratory compromise in this scenario.
