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. Laboratory results Lab results are diagnostic data, not part of the health history. They are obtained separately through testing.
B. Physical examination findings The physical exam is a separate component of the assessment and is not included in the health history, which focuses on subjective data.
C. Health habits The health history includes subjective data provided by the client, such as dietary habits, exercise routine, smoking, alcohol use, sleep patterns, and medication use. This information helps the nurse understand the client’s lifestyle and risk factors.
D. Observed client behaviors While a nurse may take note of behaviors, the health history is based on the client’s self-reported information, not observations.
Correct Answer is A
Explanation
A. "Your family member has the right to refuse care." Every competent adult has the legal and ethical right to make decisions about their own medical treatment, including the right to refuse care, even if it results in death.
B. "To continue treatment, you must be appointed as your family member's health care surrogate." The client is still competent and capable of making their own decisions, so a surrogate is not necessary or legally allowed to override their wishes.
C. "We should discuss different treatment options when your family member is not present." Discussing medical decisions behind the client’s back would be unethical and violate the principle of autonomy.
D. "I can submit your request to the ethics committee." There is no ethical dilemma here, as the client has the right to refuse treatment, and their decision must be respected.
