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.

Explanation
Indicated:
Titrate the rate of infusion to maintain the client’s blood pressure at least 90/60 mmHg: - The client is hypotensive (76/45 mmHg), likely due to acute blood loss anemia from a gastrointestinal (GI) bleed. Adjusting the transfusion rate helps stabilize BP while preventing volume overload.
Stay with the client for the first 15 minutes of the transfusion: The highest risk of a transfusion reaction (e.g., hemolysis, anaphylaxis, febrile reaction) occurs within the first 15 minutes, so the nurse must remain with the client for close monitoring.
Obtain the first unit of packed RBCs from the blood bank: The client’s condition (hypotension, tachycardia, history of melena) suggests GI bleeding and significant blood loss. RBC transfusion is required to restore oxygen-carrying capacity and improve perfusion.
Document the blood product transfusion in the client’s medical records: Proper documentation includes blood product type, volume infused, time started and completed, client response, and any adverse reactions. This ensures compliance with safety protocols.
Not Indicated:
Start an IV bolus of lactated Ringer’s solution: Lactated Ringer’s (LR) is incompatible with blood products because it contains calcium, which can cause clotting in the IV line. Normal saline (0.9% NaCl) should be used instead.

Explanation
To calculate how many tablets of levothyroxine the nurse should administer, we'll need to convert the dose to the same unit as the available tablets. Here's the step-by-step process:
Convert the desired dose to milligrams (mg): 50 micrograms (mcg) = 50 / 1000 mg (since 1 mg = 1000 mcg) 50 mcg = 0.05 mg
Now, find out how many tablets of 0.025 mg each are required to achieve the desired dose: Number of tablets = Desired dose (in mg) / Tablet strength (in mg) Number of tablets = 0.05 mg / 0.025 mg Number of tablets = 2 tablets
Therefore, the nurse should administer 2 tablets per dose.
