The correct answer is choice A, B, C, D and E.

The virus is most commonly transmitted from mother to child during birth and delivery, as well as through contact with blood or other body fluids during sex with an infected partner, unsafe injections or exposures to sharp instruments.

Choice A is correct because unprotected sexual contact can expose a person to the blood, semen, or vaginal fluids of an infected partner.

Choice B is correct because sharing drugs, needles, or “works” when using drugs can expose a person to the blood of an infected person.

Choice C is correct because poor infection control practices in medical settings can expose a person to contaminated needles or syringes or sharp objects that have been used on an infected person.

Choice D is correct because sharing of blood sugar (diabetes) testing equipment can expose a person to the blood of an infected person.

Correct Answer is C

Explanation

The correct answer is choice C. Document this as a normal finding.According to the American Academy of Family Physicians, bleeding from the dorsal slit after circumcision using a Gomco clamp is usually minimal and will stop once the clamp is in place.

Therefore, a small amount of blood on the diaper 12 hours after the procedure is not a cause for concern and does not require any intervention.

Choice A is wrong because applying gentle pressure to stop bleeding is not necessary and may cause more trauma to the wound.

Choice B is wrong because changing the diaper more frequently may also disturb the healing process and increase the risk of infection.Choice D is wrong because notifying the physician is not indicated unless there is excessive or persistent bleeding, signs of infection, or other complications.

A. Factor II B. Factor V C. Factor VIII D. Factor XI

Correct Answer is A

Explanation

The correct answer is choice A.Factor II, also known as prothrombin, is one of the coagulation factors that are activated by vitamin K.Vitamin K is a cofactor for the carboxylation of specific glutamic acid groups in coagulation factors II, VII, IX, and X.

This process is essential for the activation of these factors in the coagulation cascade.

Choice B is wrong because factor V is not a vitamin K-dependent coagulation factor.

Factor V is activated by thrombin and acts as a cofactor for factor Xa in the conversion of prothrombin to thrombin.

Choice C is wrong because factor VIII is not a vitamin K-dependent coagulation factor.

Factor VIII is activated by thrombin and acts as a cofactor for factor IXa in the activation of factor X.

Choice D is wrong because factor XI is not a vitamin K-dependent coagulation factor.

Factor XI is activated by factor XIIa and activates factor IX in the intrinsic pathway of coagulation.

Normal ranges for coagulation factors are:

• Factor II: 70-120% of normal activity

• Factor V: 50-150% of normal activity

• Factor VIII: 50-150% of normal activity

• Factor IX: 50-150% of normal activity

• Factor X: 70-140% of normal activity

• Factor XI: 70-150% of normal activity
