2. The most frequent indication for late termination of pregnancy is brain abnormalities in the fetus.
3. Feticide can be safely achieved with ultrasound-guided intracardiac injection of potassium chloride to ensure that a viable fetus with lethal congenital abnormalities is stillborn.
4. Up to 40% of patients with HIV infection will develop a neurological disorder.
5. Human T-cell lymphotropic virus type 1 (HTLV-1) is a retrovirus endemic to tropical areas.
6. Spinal cord atrophy occurs in HTLV-1-associated myelopathy.
7. Of people infected with HTLV-1, approximately 10% will develop myelopathy ('tropical spastic paraparesis').
8. In public health hospitals, mortality is steadily decreasing.
9. Organophosphates (contained in regulated agricultural insecticides and ingested to attempt suicide) cause harm by inhibiting function of the cholinesterase enzyme.

16. HIV-positive patients with high viral loads and high CD4 counts are particularly at risk of developing lymphoma.
17. The minimum requirements for basic office spirometers include forced vital capacity (FVC), forced expiratory volume (FEV) and peak expiratory flow (PEF).
18. Large-airway obstruction gives rise to a strikingly abnormal flow volume loop with the shape of a hamburger.
19. Spirometry is indicated for monitoring the course of chronic obstructive airways disease.
20. Concerning spirometers, provided in-line filters are used, special precautions for patients with transmissible infections such as tuberculosis are unnecessary.
