( Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero. TYPE THE ANSWER ONLY, no label )
The Correct Answer is ["6"]
To calculate the amount of ampicillin needed for one dose, we need to use a proportion. We can set up the proportion as follows:
150 mg / x mL = 125 mg / 5 mL
We can cross-multiply and solve for x:
150 * 5 = 125 * x
750 = 125 * x
x = 750 / 125
x = 6
Therefore, we need 6 mL of ampicillin for one dose

Explanation
To administer the ordered dose of digoxin, you need to calculate how many tablets of the available strength are equivalent to 0.25 mg. You can use the formula:
Ordered dose / Available dose = Number of tablets
Plugging in the values, you get:
0.25 mg / 0.125 mg = 2 tablets
Therefore, you need to administer two tablets of digoxin 0.125 mg to give the ordered dose of 0.25 mg.
Correct Answer is ["A","D","E"]
Explanation
A. Client reports feeling dizzy when sitting up from a supine position.
Dizziness or lightheadedness when moving from a lying down to a sitting or standing position can be indicative of orthostatic hypotension.
B. Client reports feeling palpitations when rising from a supine to a standing position.
Palpitations (feeling of rapid or irregular heartbeat) can be associated with orthostatic changes and may indicate the heart's compensatory response to low blood pressure.
C. Erythema is present on the bilateral lower extremities.
Erythema (redness of the skin) is not typically associated with orthostatic hypotension. This symptom is more likely related to skin conditions or other causes.
D. The client has a temperature of 100.4 F.
Fever (elevated body temperature) is not a direct symptom of orthostatic hypotension. Orthostatic hypotension is primarily related to changes in blood pressure upon assuming an upright position.
E. The client states, “I feel lightheaded when sitting up.”
Lightheadedness upon sitting up or standing is a common symptom of orthostatic hypotension.
