A 24-year-old patient who is an intravenous drug user asks the nurse about preventing acquired immunodeficiency syndrome (AIDS). The nurse informs the patient that the risk of developing the human immunodeficiency virus (HIV) infection from drug use can be reduced by:
not having sexual intercourse under the influence of drugs.
asking those who they share equipment with to be tested for HIV.
participating in a needle exchange program.
cleaning syringe with betadine before use.
The Correct Answer is C
A. Avoiding sexual intercourse under the influence of drugs reduces certain risks but does not address the specific risk of needle transmission.
B. Asking others to be tested for HIV may be unrealistic and does not prevent HIV transmission through shared equipment.
C. Participating in a needle exchange program reduces the risk of HIV transmission by providing sterile needles, lowering the likelihood of infection from shared or contaminated needles.
D. Cleaning needles with betadine is not effective for HIV prevention; only sterile, unused needles should be used.

A. Metoprolol, a beta-blocker, decreases the heart rate and reduces myocardial oxygen demand by lowering the workload on the heart, which is beneficial for managing unstable angina.
B. While metoprolol has some vasodilatory effects, its primary action is to reduce heart workload, not to dilate coronary arteries.
C. Although beta-blockers can reduce the risk of arrhythmias, the main purpose in angina management is to decrease cardiac workload.
