Ordered: Hydroxyzine (Vistaril) 35 mg IM stat

Available: Hydroxyzine (Vistaril) 50 mg/mL

Administer: ____ ml

Answer and Explanation

The Correct Answer is ["0.7"]

To calculate the amount of hydroxyzine (Vistaril) to administer, use the formula:

D (desired dose) / H (have dose) x Q (quantity) = X (amount to give)

In this case, D = 35 mg, H = 50 mg/mL, and Q = 1 mL. Plug in the values and solve for X:

35 mg / 50 mg/mL x 1 mL = 0.7 mL

Therefore, the amount of hydroxyzine (Vistaril) to administer is 0.7 mL.

Correct Answer is C

Explanation

A. Assess the pedal pulses with a Doppler device:

Assessing the pedal pulses with a Doppler device may be useful in certain situations, but when the radial pulse is irregular, it's more important to assess the central (apical) pulse to get a more accurate representation of the heart's rhythm.

B. Assess the apical pulse with a Doppler device:

While using a Doppler device on the apical pulse is an option, it's generally not the first choice when assessing irregular pulses. The apical pulse can often be palpated manually, and it's more practical to assess it directly for irregularities.

C. Assess the apical pulse for a full minute:

This is the recommended action when the radial pulse is irregular. By assessing the apical pulse for a full minute, the nurse can accurately determine the heart rate and identify any irregularities in rhythm, providing a comprehensive assessment of the cardiac status.

D. Assess the pedal pulses for a full minute:

While assessing the pedal pulses is important in certain situations, it may not be the priority when dealing with an irregular radial pulse. Assessing the apical pulse for a full minute gives a more direct and accurate reflection of the heart's rhythm.

Correct Answer is ["6"]

Explanation

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
