A nurse is preparing to administer phenobarbital 30 mg PO to a client. Available is phenobarbital 20 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["7.5"]
To calculate the correct dosage, use the formula:
Dose to administer = (Desired dose/Available dose) ×Volume available
Given:
Desired dose = 30 mg
Available ,dose = 20 mg
Volume available = 5 mL
(30mg/20mg) × 5ml = 7.5ml
Final Answer:
7.5 mL

Correct Answer is C
Explanation
A. "A client was placed in the waiting room based on their triage assessment." Hospitals can prioritize clients based on triage assessment as long as they receive a medical screening examination and stabilizing treatment if necessary.
B. "A client was transferred to the inpatient antepartum unit to rule out preterm labor." EMTALA requires that hospitals evaluate and stabilize clients with emergency medical conditions, including preterm labor. Transferring a client within the same facility for further evaluation does not violate EMTALA.
C. "A client was referred to the county hospital for medical screening evaluation." Under EMTALA, hospitals must provide a medical screening examination and necessary stabilizing treatment before referring or transferring a client, regardless of their insurance status. Sending a client elsewhere for evaluation without treatment is a violation.
D. "A stable client was transferred to a public hospital that provides reduced-cost care." Once a client has been stabilized, hospitals may arrange for transfer to another facility, provided the transfer meets EMTALA guidelines and is in the client's best interest.
Correct Answer is A
Explanation
A. "Use IV tube ports when injecting medications." Latex-free IV ports should be used instead of rubber stoppers found in some IV bags and vials.
B. "Remove medication from multi-dose vials with the stopper in place." Many vial stoppers contain latex, so the nurse should use single-dose vials or vials labeled as latex-free.
C. "Secure loose cords in stockinette with tape." Stockinettes are sometimes made with latex, posing a risk to the client. Non-latex materials should be used instead.
D. "Schedule the client's surgery as the last procedure of the day." Clients with latex allergies should be scheduled first to minimize exposure to airborne latex particles from gloves and equipment used earlier in the day.
