WGU D027 EXAM 1
A patient has a disorder affecting ventricular depolarization. What ECG finding with the nurse associate with this?
- Absence of P waves
- Short PR interval
- QT interval variability
- Prolonged QRS interval - ANSWER-D. Prolonged QRS interval
--The QRS complex represents the sum of all ventricular muscle cell depolarization therefore a prolonged QRS interval would be suggestive ventricular depolarization abnormalities. For example, heart failure or bundle branch block or myocardial infarction.

Which of the following conditions is contraindicated in using thrombotic therapy?
- History of hemorrhagic stroke
- Peptic ulcer disease
- Concurrent use of Coumadin

A patient with chronic migraines arrives for a neurological evaluation. The neurologist recommends preventative therapy. Which one (1) of the following medications is used to prevent the frequency of chronic migraines?
- Verapamil
- Dihydroergotamine
- Naproxen
- Sumatriptan - ANSWER-A. Verapamil
-- Calcium channel blockers have demonstrated efficacy in investigative use for prophylaxis of migraine and cluster headaches. In particular, verapamil, with its low side-effect profile, appears to be a promising alternative to the currently available agents for prophylactic treatment of chronic recurring headaches.
Which of the following antihypertensive mediations should the nurse practitioner avoid when treating a patient with emphysema?
- Calcium channel blockers
- Beta blockers
- Angiotensin converting enzyme inhibitors
- Diuretics - ANSWER-B. Beta blockers
- / 4
--Beta blockers, specifically the beta-2 blockers result in bronchoconstriction therefore they should be avoided in patients with chronic respiratory conditions.

4 Which vitamin may be used as concomitant therapy in managing a patient with schizophrenia?
- Vitamin B1
- Vitamin C
- Vitamin D
- Vitamin E - ANSWER-A. Vitamin B1

A 29 yo pregnant patient presents with a pulmonary embolus (PE). Which medication should the nurse anticipate giving?

- Fondaparinux
- Unfractionated heparin
- Vitamin K - ANSWER-C. Unfractionated heparin
