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 A
Explanation
A. Consider gender and age when selecting an interpreter Cultural preferences may influence comfort and communication. For example, a client may feel more comfortable speaking with an interpreter of the same gender or age group.
B. Direct comments and questions to the interpreter The nurse should speak directly to the client, not the interpreter, to maintain engagement and respect.
C. Speak to the client in a loud voice Speaking louder does not improve comprehension and may come off as disrespectful. Clear, slow speech is more effective.
D. Ask a member of the client's family to serve as an interpreter Family members may omit or alter information and are not trained in medical terminology or confidentiality laws. A professional medical interpreter should be used.
Correct Answer is D
Explanation
A. "Previous caregiver experience." Experience may reduce stress by helping the caregiver develop coping strategies.
B. "25 to 50 years of age." Age alone is not a significant risk factor for caregiver burden.
C. "Lives in a different dwelling than the client." Caregivers living separately may experience less strain than those providing full-time, in-home care.
D. "Providing care for greater than 1 year." Long-term caregiving is associated with burnout, stress, and physical health issues, increasing the caregiver's risk of anxiety, depression, and chronic illness.
