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.)

A. A quiet, restful environment:
While a quiet and restful environment may be beneficial for general comfort, it does not specifically address the visual issues related to the use of mydriatic medications. Mydriatics cause pupil dilation, which can increase sensitivity to light, so a dimly lit room is more appropriate for managing light sensitivity.

B. A dimly lit room:
A dimly lit room is best for a client receiving mydriatic medication because mydriatics cause pupil dilation, which can lead to increased sensitivity to light and difficulty with bright environments. Reducing light exposure helps manage these symptoms and improve comfort.

C. A warm room temperature:
While maintaining a comfortable room temperature is important, it does not specifically address the visual discomfort caused by mydriatic medications. The primary concern here is light sensitivity, which is better managed with dim lighting rather than room temperature.

D. Cool, humidified air:
Cool, humidified air can be helpful for certain respiratory conditions or comfort but does not directly address the issue of light sensitivity associated with mydriatic medication use. The focus should be on managing light exposure rather than air quality.

A) Check for correct placement of the patch behind the client's ear: While ensuring correct placement is important for the effectiveness of transdermal patches, the scopolamine patch is primarily used for motion sickness and nausea, not for pain relief. Checking placement does not address the client's pain, which is not the intended use of the medication.

B) Explain that the medication is not given to prevent pain: Scopolamine is used to prevent nausea and motion sickness, not to manage pain. The client’s pain is unrelated to the patch’s intended purpose. Educating the client about the medication's purpose and recommending appropriate pain management would address the issue effectively.

C) Advise the client that the effects of the medication have worn off: The scopolamine patch's effects for nausea or motion sickness would not typically wear off within four hours. The medication was not intended to address pain, so advising the client about its effectiveness for nausea rather than pain would be more appropriate.

D) Offer to apply a new transdermal patch to relieve the pain: Applying a new patch would not be effective for pain management, as scopolamine is not designed for pain relief. Instead, the focus should be on addressing the client's pain with suitable analgesics and explaining the purpose of the scopolamine patch.
