The client has been receiving clonidine 0.1 mg via transdermal patch once every 7 days. The NA removes the patch with morning cares. Eight hours later, the nurse discovers that the clonidine patch is no longer present. Which assessment finding should be most concerning to the nurse?

- B. Client reports having an excruciating headache.
- C. Blood pressure is noted to be 182/100 mm Hg.
- D. The ECG monitor shows a heart rate of 120 bpm.
Correct Answer: C
Rationale: A: Although a skin tear is concerning and may have occurred during removal, it is not the most concerning. B: Headache can occur from the abrupt removal of clonidine but is not the most concerning. C: Clonidine (Catapres) is an antihypertensive medication. Rebound hypertension occurs from abrupt withdrawal. Immediate intervention is required to lower the BP. D: Tachycardia is an adverse effect of clonidine.

The LPN needs to determine the client's respiratory rate. What is the best technique to do this?
- A. Tell the client you need to count their respiratory rate.
- B. Subtly watch the client from across the room when they are doing an activity.
- C. Ask the client to sit still for 30 seconds.
- D. Count respirations while pretending to check the client's pulse.
Correct Answer: D
Rationale: You should not tell the client you are counting their respirations, as this may cause them to alter their breathing pattern. Pretending to check a pulse allows you to get close to the client without cluing them in to what you are assessing. Standing across the room is not the best way to assess for respirations as they may be difficult to see.
