1. What is one characteristic of human immunodeficiency virus (HIV)?

Correct answer: C

Rationale: The correct answer is C. HIV integrates its genetic material into the host cell's DNA. The virus uses the enzyme reverse transcriptase to make a DNA copy of its RNA, which is then inserted into the genetic material of the infected cell. Choice A is incorrect because the presence of antibodies does not indicate immunity to HIV but rather exposure to the virus. Choice B is incorrect as HIV replication occurs intracellularly, inside the host cell. Choice D is irrelevant to the characteristics of HIV.

2. A nurse working in a surgical unit notices a patient experiencing SOB, calf pain, and warmth over the posterior calf. All of these symptoms may indicate which of the following medical conditions?

Correct answer: A

Rationale: The correct answer is that the patient may have a DVT (Deep Vein Thrombosis). SOB (Shortness of Breath), calf pain, and warmth over the posterior calf are classic signs and symptoms of DVT. DVT is a serious condition where a blood clot forms in a deep vein, commonly in the legs. Choices B, C, and D are incorrect because dermatitis does not typically present with these symptoms, late stages of CHF would manifest with other signs, and anxiety after surgery usually does not produce these specific symptoms.

3. The emergency department charge nurse is reviewing the clients triaged in the last 30 minutes. The nurse is required to obtain a social service consult from which of the following clients?

Correct answer: A

Rationale: For children under 7 years, most states have laws that mandate reporting certain situations to social services or child protection, such as ingestions of toxic substances, fractures, suspected neglect, or abuse, and burns. In this scenario, the 6-year-old who drank diluted bleach falls under the category that requires a social service consult. The other choices involve injuries or conditions that may warrant medical attention but do not necessarily mandate a social service consult based on age-related legal requirements.

4. An infection in a central venous access device is not eliminated by giving antibiotics through the catheter. How might bacterial glycocalyx contribute to this?

Correct answer: A

Rationale: Bacterial glycocalyx is a viscous polysaccharide or polypeptide slime that covers microbes. It plays a significant role in protecting bacteria by enhancing adherence to surfaces, resisting phagocytic engulfment by white blood cells, and preventing antibiotics from contacting the microbe. Choice A is correct because glycocalyx shields the bacteria from both antibiotics and the immune system, allowing the infection to persist. Choices B, C, and D are incorrect because glycocalyx does not neutralize antibiotics, compete for binding sites with antibiotics, or provide nutrients for microbial growth.

5. Which hormone is responsible for amenorrhea in the pregnant woman?

Correct answer: A

Rationale: Correct! Progesterone is the hormone responsible for amenorrhea in pregnant women. Progesterone plays a crucial role in maintaining the uterine lining for implantation and supporting early pregnancy. High levels of progesterone during pregnancy suppress the normal menstrual cycle, leading to amenorrhea. Estrogen, FSH, and hCG do not directly cause amenorrhea in pregnant women. Estrogen is involved in the development of female secondary sexual characteristics, FSH is involved in the growth and maturation of ovarian follicles, and hCG is produced by the placenta to support the production of progesterone during pregnancy.
