Which antiparkinsonian drug is associated with the on-off phenomenon and the wearing-off effect?
- A. Amantadine
- B. Levodopa
- C. Benztropine
- D. Pramixole
Correct Answer: B
Rationale: Levodopa is the antiparkinsonian drug associated with the on-off phenomenon and the wearing-off effect. The on-off phenomenon refers to the sudden and unpredictable fluctuations between periods of symptom control (on) and periods of symptom re-emergence (off) in patients with Parkinson's disease receiving levodopa therapy. This can happen as the disease progresses and the brain becomes less responsive to the medication.

Which of the ff finding would confirm that a female client has mastitis? Choose all that apply
- A. A crack in the nipple or the areola
- B. Multiple lumps within the breast tissue
- C. Swollen, firm, and hard breasts
- D. Enlargement of the axillary lymph nodes
Correct Answer: C
Rationale: Mastitis is an inflammatory condition of the breast tissue, often caused by an infection. Common symptoms of mastitis in a female client include swollen, firm, and hard breasts. These changes in breast tissue texture are indicative of inflammation and infection. Other possible signs of mastitis may include redness, warmth, and tenderness in the affected breast. The presence of swollen, firm, and hard breasts would confirm the diagnosis of mastitis in a female client.

An elderly patient, Mr. Cruz is being cared for by nurse Bennie because of pulmonary embolism. Nurse Bennie would anticipate an order for immediate administration of:
- A. warfarin
- B. heparin
- C. dexamethazone
- D. protamine sulfate
Correct Answer: B
Rationale: In the scenario of an elderly patient like Mr. Cruz with suspected pulmonary embolism, the nurse would anticipate an order for the immediate administration of heparin. Heparin is an anticoagulant medication that works quickly to prevent the further development of blood clots. It is often used as the initial treatment for pulmonary embolism to prevent existing blood clots from getting larger and reduce the risk of new clots forming. Heparin is preferred over warfarin initially because it has a more rapid onset of action. Warfarin, which is a commonly used anticoagulant for longer-term management, takes several days to reach its full effect and requires monitoring of the prothrombin time (INR). Therefore, in Mr. Cruz's acute situation, heparin would be the most appropriate choice for immediate intervention to address the pulmonary embolism.
A patient had a lumbar injury. Which neurological test by the nurse would be affected?
- A. Rhine's test
- B. Pupillary reaction
- C. Romberg's test
- D. Patellar reflex
Correct Answer: C
Rationale: Romberg's test is a neurological test that assesses the function of the dorsal columns of the spinal cord, which are responsible for proprioception and vibration sensations. A lumbar injury can affect these dorsal columns, leading to impaired proprioception. Therefore, the Romberg's test would be affected due to the compromised sensory input from the lower extremities. This test usually involves asking the patient to stand with feet together and eyes closed to assess balance and proprioception.
