A client receives a prescription for penicillin 1.2 million units IM. The available vial is labeled, "600,000 units/2 mL." How many mL should the nurse administer? (Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["4"]

Calculations:

Desired dose: 1.2 million units

Available dose: 600,000 units/2 mL

To find the volume to administer, we can use the following formula:

Volume to administer = (Desired dose / Available dose) * Volume per dose

Volume to administer = (1,200,000 units / 600,000 units/mL) * 2 mL = 4 mL

Therefore, the nurse should administer 4 mL of the penicillin solution.

Correct Answer is D

Explanation

A) Avoid prolonged exposure to direct sunlight: While erythromycin can increase sensitivity to sunlight, this is not directly related to the interaction between oral contraceptives and erythromycin. The primary concern with erythromycin and oral contraceptives is their interaction rather than sun exposure.

B) Stop the oral contraceptive immediately: There is no need to stop oral contraceptives when taking erythromycin. However, erythromycin can potentially reduce the effectiveness of oral contraceptives, so additional precautions should be taken rather than discontinuing the contraceptive.

C) Take the medications at least 12 hours apart: Timing of administration is not a primary concern for this interaction. The main issue is the potential reduction in contraceptive efficacy rather than timing the doses of the medications.

D) Use an additional form of contraception: Erythromycin can potentially decrease the effectiveness of oral contraceptives due to its effect on liver enzymes and drug metabolism. It is advisable to use an additional form of contraception to prevent unintended pregnancy while taking erythromycin.

A. Perform a bladder scan. B. Obtain daily weights. C. Assess urine output. D. Monitor blood pressure.

Correct Answer is D

Explanation

A. Perform a bladder scan:
This intervention is useful for assessing urinary retention or post-void residual volumes but is not specifically related to monitoring the adverse effects of tamsulosin.

B. Obtain daily weights:
Daily weights are typically used to monitor fluid balance and signs of fluid retention, not specifically for adverse reactions to tamsulosin.

C. Assess urine output:
While monitoring urine output can be important in managing BPH, it is not specifically targeted to identify adverse reactions to tamsulosin.

D. Monitor blood pressure:
Tamsulosin, an alpha-1 blocker, can cause orthostatic hypotension (a drop in blood pressure when standing up) and dizziness. Monitoring blood pressure helps detect this potential adverse effect, ensuring the client is not experiencing significant drops in blood pressure.
