The practical nurse (PN) believes that a prescription for a child is incorrect because the dosage prescribed is the usual adult dosage. Which action should the PN take?
Ask another nurse if adult dosages are ever given to children.
Call the healthcare provider and clarify the prescription.
Request verification of the prescription by the charge nurse.
Tell the pharmacy to send an accurate child's dosage.
The Correct Answer is B
Choice A rationale:
Asking another nurse about administering adult dosages to children may provide some insights, but it is not a reliable or definitive source of information. The PN should directly communicate with the healthcare provider who wrote the prescription to ensure accuracy and safety.
Choice B rationale:
Call the healthcare provider and clarify the prescription.
Choice C rationale:
While requesting verification from the charge nurse is reasonable, the charge nurse may not have the authority to change or clarify the prescription. The most appropriate action is to directly contact the healthcare provider responsible for the child's care.
Choice D rationale:
Telling the pharmacy to send an accurate child's dosage assumes that the pharmacy made an error, which may not be the case. The PN should confirm the prescription with the healthcare provider to avoid potential mistakes or misunderstandings.

Correct Answer is A
Explanation
Glaucoma is a group of eye diseases that damage the optic nerve and cause vision loss. It is often associated with increased intraocular pressure, which can compress the nerve fibers and reduce blood flow to the retina. The most common type of glaucoma, open-angle glaucoma, causes gradual loss of peripheral vision.
The other options are not correct because:
A. Macular edema is a condition that causes swelling and fluid accumulation in the macula, the central part of the retina that is responsible for sharp and detailed vision. It can cause blurred or distorted vision, but it does not affect the optic nerve or the peripheral vision.
B. Cataract is a condition that causes clouding of the lens, which is the transparent structure that focuses light onto the retina. It can cause blurred, dim, or yellowed vision, but it does not affect the optic nerve or the intraocular pressure.
C. Diabetic retinopathy is a complication of diabetes that damages the blood vessels in the retina and causes bleeding, leakage, or scarring. It can cause blurred, fluctuating, or darkened vision, but it does not affect the optic nerve or the intraocular pressure.
Correct Answer is A
Explanation
The correct answer is choice A: Never scratch under the cast.
Choice A rationale:
It is important not to scratch under the cast because inserting objects can lead to skin injury and infection. If itching occurs, blowing cool air from a hair dryer into the cast is recommended.
Choice B rationale:
While mild swelling and some discomfort are common after a cast is applied, patients should not expect an increase in pain. Persistent or severe pain could indicate complications such as increased swelling, decreased blood flow, or pressure on nerves and should be evaluated by a healthcare provider.
Choice C rationale:
Applying a cold pack to “hot spots” on the cast is not recommended as it can lead to moisture accumulation and skin problems. Instead, to manage swelling and discomfort, ice can be applied over the cast, covered with a thin towel, for 20 minutes every two hours while awake during the first 48 hours.
Choice D rationale:
Keeping the injured leg in a dependent position is not advised because it can increase swelling and pain. The affected limb should be elevated above the level of the heart to reduce swelling and promote healing.
