The physician orders Lorabid 350 mg po for pneumonia. After reconstitution, the medication is available as 200 mg/5 mL. How many milliliters will the nurse administer? Round to tenths.
The Correct Answer is ["8.8"]
Ordered dose: 350 mg
Available concentration: 200 mg per 5 mL
Step 1: Use the formula
mL to give = (Desired dose ÷ Available dose) × Volume
mL to give = (350 ÷ 200) × 5
mL to give = 1.75 × 5
mL to give = 8.75
Step 2: Round to the nearest tenth
8.75 → 8.8
Final Answer: 8.8 mL

Correct Answer is A
Explanation
A. Placing the tablet under the tongue allows for rapid absorption through the mucous membranes, providing quick relief of anginal pain—typically within 1 to 3 minutes.
B. Nitroglycerin acts quickly; waiting up to 15 minutes is not accurate. Clients should seek emergency care if pain persists after 3 doses taken 5 minutes apart.
C. Headache is a common side effect due to vasodilation and is not a reason to discontinue the medication; clients can manage it with mild analgesics.
D. Clients may take nitroglycerin prophylactically before activities (e.g., exercise, sexual activity) that may trigger angina. Avoiding use prior to exertion is not recommended.
Correct Answer is D
Explanation
