A nurse at a provider's office is collecting data from a client who reports taking pseudoephedrine for sinus problems. The nurse should recognize that which of the following conditions from the client's history places the client at risk for harm while taking pseudoephedrine?
Overweight
Migraine headaches
Eczema
Hypertension
The Correct Answer is D
A. Overweight. While weight can affect medication metabolism, it does not specifically increase risk with pseudoephedrine.
B. Migraine headaches. Migraine headaches are not contraindicated with pseudoephedrine, although some stimulants can increase headaches.
C. Eczema. Pseudoephedrine does not typically affect eczema.
D. Hypertension. Pseudoephedrine is a decongestant that can increase blood pressure, so it should be used with caution in clients with hypertension.

B. Myoglobin: Myoglobin rises within hours but returns to normal within 24 hours after MI.
C. Creatinine kinase-MB (CK-MB): CK-MB peaks 12-24 hours post-MI and returns to baseline within 2-3 days.
D. Troponin T: Troponin T remains elevated for up to 10-14 days after an MI, providing long-term evidence of myocardial injury.
Correct Answer is D
Explanation
A. Schedule deep tissue massage with physical therapy. Massaging the area is contraindicated in cases of suspected deep vein thrombosis (DVT), as it can dislodge the clot, leading to a pulmonary embolism.
B. Monitor Homan's sign. Homan’s sign (pain in the calf upon dorsiflexion) is no longer considered a reliable or safe assessment for DVT due to the risk of dislodging a clot.
C. Obtain platelet aggregation studies. Platelet aggregation studies are not specific to diagnosing a DVT; instead, imaging is preferred.
D. Arrange for a venous duplex ultrasound. A venous duplex ultrasound is a non-invasive test that can confirm the presence of a DVT in the affected extremity.
