A nurse is teaching a client about using transdermal scopolamine to treat motion sickness.
Which of the following instructions should the nurse include?
"Store unused patches in the refrigerator.”
"Apply the patch prior to traveling.”
"Place the patch on your upper arm.”
"Replace a dislodged patch onto the same location.”
The Correct Answer is B
Choice A rationale:
Storing unused patches in the refrigerator is not necessary for transdermal scopolamine patches. Refrigeration is not a requirement for their storage.
Choice B rationale:
Applying the patch prior to traveling is the correct choice. Transdermal scopolamine patches are used to prevent motion sickness. Applying the patch before the journey allows the medication to be absorbed before exposure to motion, ensuring its effectiveness during travel.
Choice C rationale:
Placing the patch on the upper arm is a specific and correct instruction for applying transdermal scopolamine patches. The patch should be placed on a clean, dry, and hairless area of the skin, preferably behind the ear or on the upper arm.
Choice D rationale:
Replacing a dislodged patch onto the same location is incorrect. If the patch becomes dislodged, it should be replaced with a new patch on a different, clean, and dry area of the skin. Reapplying a dislodged patch to the same spot may result in uneven absorption and reduced effectiveness.

Correct Answer is D
Explanation
Choice A rationale:
An increase in heart rate by 10 beats per minute when moving from a supine to a sitting position is a normal physiological response to compensate for decreased venous return and maintain cardiac output. This response does not indicate orthostatic hypotension.
Choice B rationale:
An increase in diastolic blood pressure by 10 mm Hg when moving from a supine to a sitting position is a normal response to compensate for the effects of gravity on blood flow. It helps maintain perfusion to vital organs and does not indicate orthostatic hypotension.
Choice C rationale:
Heart palpitations can occur due to various reasons, including anxiety or arrhythmias, but they are not specific signs of orthostatic hypotension. This symptom alone does not confirm the presence of orthostatic hypotension.
Choice D rationale:
A decrease in systolic blood pressure by 25 mm Hg or more when moving from a supine to a sitting position indicates orthostatic hypotension. Orthostatic hypotension is defined as a drop in systolic blood pressure of 20 mm Hg or more or a drop in diastolic blood pressure of 10 mm Hg or more within 3 minutes of standing up. This condition can cause dizziness, lightheadedness, or fainting and can be a side effect of antihypertensive medications or other underlying medical conditions.
Correct Answer is D
Explanation
A. Penicillin G should be infused slowly over a period of 10 to 15 minutes to prevent adverse reactions such as seizures.
B. Incorrect. Checking for a sulfa allergy is not relevant to the administration of penicillin, as sulfa and penicillin are different types of antibiotics.
C. Incorrect. Refrigeration is not typically required for penicillin G after reconstitution.
D. IDiarrhea can be a sign of a serious condition called antibiotic-associated colitis, which requires immediate medical attention.
