Correct Answer is B

Explanation

A. The low blood pressure (90/64) may indicate hypovolemia or shock but is not specific for ICP concerns.

B. This set of vital signs is concerning due to the extremely high blood pressure (220/46) combined with a very low heart rate (30) and low respiratory rate (6), which can indicate an autonomic response to increased ICP, potentially leading to Cushing's triad (hypertension, bradycardia, and irregular respirations).

C. Although the blood pressure is high (200/94), the heart rate is normal and the respiratory rate is stable, making this less alarming compared to option B.

D. The elevated temperature and abnormal heart rate (132) indicate potential fever and tachycardia, but the blood pressure (82/50) is low and does not directly indicate increased ICP.

A. Sharing eating utensils B. Sharing a razor C. Kissing on the mouth D. Using the same toilet

Correct Answer is B

Explanation

A. Sharing eating utensils does not transmit HIV, as the virus is not spread through saliva.

B. Sharing razors is a high-risk activity for transmitting HIV because it can involve direct blood-to-blood contact if the razor causes cuts.

C. HIV transmission through kissing is highly unlikely due to low levels of the virus in saliva.

D. HIV cannot be spread through shared toilets, as the virus does not survive on surfaces and is not spread through casual contact.
