Which of the following is transmitted through direct contact with the blood or body fluid of someone who is infected (usually through unprotected sex, sharing needles, or passed from a mother to a baby at birth)? Symptoms may take 10 years or more to show. Once they appear, the person is susceptible to life-threatening infections.
Herpes simplex virus
Human papillomavirus
Human immunodeficiency virus
Cytomegalovirus
The Correct Answer is C
Choice A reason: Herpes simplex virus is incorrect because it is not the infection described in the question. It is transmitted through direct contact with the skin or mucous membranes of someone who is infected, usually through oral or genital sex. Symptoms include painful blisters and sores in the mouth or genitals. It does not cause life-threatening infections, but it can increase the risk of other sexually transmitted infections.
Choice B reason: Human papillomavirus is incorrect because it is not the infection described in the question. It is transmitted through direct contact with the skin or mucous membranes of someone who is infected, usually through genital sex. Symptoms include genital warts and cervical cancer. It does not cause life-threatening infections, but it can increase the risk of other cancers.
Choice C reason: Human immunodeficiency virus is correct because it is the infection described in the question. It is transmitted through direct contact with the blood or body fluid of someone who is infected, usually through unprotected sex, sharing needles, or passed from a mother to a baby at birth. Symptoms may take 10 years or more to show. Once they appear, the person is susceptible to life-threatening infections, such as pneumonia, tuberculosis, or cancer. This condition is also known as acquired immunodeficiency syndrome (AIDS).
Choice D reason: Cytomegalovirus is incorrect because it is not the infection described in the question. It is transmitted through direct contact with the saliva, urine, or breast milk of someone who is infected, usually through kissing, sexual contact, or breastfeeding. Symptoms are usually mild or absent in healthy people, but they can be serious in people with weakened immune systems or unborn babies. It does not cause life-threatening infections, but it can cause birth defects, hearing loss, or vision problems.

Correct Answer is B
Explanation
Choice A reason: This is too short of a time frame for seroconversion to occur. Seroconversion is the process of developing antibodies to HIV, which can be detected by a blood test. It usually takes several weeks for the immune system to produce enough antibodies to be measurable.
Choice B reason: This is the typical time frame for seroconversion to occur. Most people will develop antibodies to HIV within 6 to 12 weeks after exposure. However, some people may take longer, up to 6 months or more.
Choice C reason: This is the upper limit of the time frame for seroconversion to occur. Some people may have a delayed antibody response to HIV, especially if they have a weakened immune system or take antiretroviral drugs. Therefore, it is recommended to repeat the HIV test after 6 months of exposure to confirm the diagnosis.
Choice D reason: This is an arbitrary time frame that does not reflect the average or the range of seroconversion. It is neither too short nor too long, but it is not accurate.
Correct Answer is B
Explanation
Choice A reason: Reducing stress level is a good practice for a pregnant client, as it can lower the risk of complications such as preterm labor, hypertension, and low birth weight. Therefore, this statement does not indicate a need for further teaching.
Choice B reason: Using only nonprescription medications while pregnant is a dangerous and incorrect practice, as some over-the-counter drugs can harm the fetus or cause birth defects. The client should always consult with their doctor before taking any medication, whether prescription or nonprescription. Therefore, this statement indicates a need for further teaching.
Choice C reason: Monitoring weight gain during pregnancy is a recommended practice, as it can help the client and the doctor assess the health and growth of the fetus. The client should follow the guidelines for appropriate weight gain based on their pre-pregnancy body mass index (BMI). Therefore, this statement does not indicate a need for further teaching.
Choice D reason: Telling the doctor before using home remedies for nausea is a prudent practice, as some herbal or natural remedies can interact with medications or cause adverse effects on the fetus. The client should also avoid self-medication and seek medical advice for persistent or severe nausea. Therefore, this statement does not indicate a need for further teaching.
