A nurse is preparing to administer vitamin K 1mg IM to a newborn. Available is vitamin K injection 1 mg/0.5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
To administer the correct dose of vitamin K, which is 1 mg, the nurse should refer to the concentration of the available vitamin K injection.
The available concentration is 1 mg per 0.5 mL. Therefore, to deliver a dose of 1 mg, the nurse needs to administer 0.5 mL. When rounding to the nearest tenth, the amount remains 0.5 mL.

Correct Answer is A
Explanation
A. A lithium level of 1.2 mEq/L falls within the therapeutic range (0.6-1.2 mEq/L) for the treatment of bipolar disorder. Therefore, the nurse should administer the regular dose of lithium as prescribed and closely monitor the client for any side effects.
B. Repeating the lithium level is unnecessary because the current level is within the therapeutic range. Repeated testing may be warranted if the level is outside the therapeutic range or if there are clinical concerns.
C. This action is not indicated for a lithium level within the therapeutic range. ECG and seizure precautions are typically reserved for lithium toxicity, which presents with levels above the therapeutic range.
D. Increasing the dose of lithium is not warranted when the current level is within the therapeutic range. Doing so could increase the risk of toxicity.
Correct Answer is A
Explanation
A. Azithromycin is an antibiotic commonly used to treat infections such as chlamydia. While it's generally well-tolerated, it can rarely cause serious side effects such as allergic reactions or severe skin reactions. Sore throat or fever may indicate such adverse effects, and patients
should be instructed to contact their healthcare provider immediately if they experience these symptoms.
B. Dark yellow or orange urine is not a typical side effect of azithromycin. It can be caused by drugs such as rifampin.
C. Taking azithromycin with an antacid is generally not necessary and may interfere with the absorption of the medication. It's usually recommended to take azithromycin on an empty stomach, at least 1 hour before or 2 hours after meals, unless otherwise directed by a healthcare provider.
D. Bleeding gums are not a common side effect of azithromycin. If a patient experiences unusual bleeding or bruising, they should seek medical attention, but this symptom is not specifically associated with azithromycin use.
