1. What is one characteristic of human immunodeficiency virus (HIV)?
- A. The presence of circulating antibodies that neutralize HIV is evidence of exposure to HIV.
- B. HIV replication occurs intracellularly.
- C. HIV integrates its genetic material into the host cell's DNA.
- D. DNA replication is irrelevant to 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. The factor that most determines drug distribution is:
- A. vascular perfusion of the tissue or organ.
- B. salt form.
- C. drug interactions.
- D. steady state.
Correct answer: A
Rationale: The correct answer is 'vascular perfusion of the tissue or organ.' Drug distribution is primarily determined by how well the circulatory system delivers the drug to various tissues and organs. Adequate perfusion ensures proper distribution of the drug throughout the body. While the salt form (choice B), drug interactions (choice C), and steady state (choice D) can influence drug efficacy and metabolism, they are not as crucial as vascular perfusion for the initial distribution of a drug.
3. Support systems during the grieving process include all of the following except:
- A. a despondent friend.
- B. a nurse.
- C. a social worker.
- D. a family member.
Correct answer: B
Rationale: During the grieving process, it is essential to have a support system in place. Options B, C, and D - a nurse, a social worker, and a family member, respectively, are individuals who can provide comfort, guidance, and practical assistance to someone who is grieving. However, a despondent friend, as stated in the question, is not an ideal choice for support during this period. A despondent friend is someone who is feeling extremely unhappy and discouraged, and may not have the emotional capacity to provide the needed support to a grieving individual. It is important for someone who is grieving to have support from individuals who can offer understanding, empathy, and strength, which a despondent friend may struggle to provide.
4. One day postoperative, the client complains of dyspnea, and his respiratory rate (RR) is 35, slightly labored, and there are no breath sounds in the lower-right base. The nurse should suspect:
- A. cor pulmonale.
- B. atelectasis.
- C. pulmonary embolism.
- D. cardiac tamponade.
Correct answer: B
Rationale: The correct answer is atelectasis. The absence of breath sounds in the lower-right base is a key finding in atelectasis, which occurs when a portion of the lung collapses. The other symptoms such as dyspnea and increased respiratory rate could be present in various pulmonary conditions. Cor pulmonale is typically associated with chronic lung disease, pulmonary embolism presents with sudden onset dyspnea and chest pain, and cardiac tamponade manifests with Beck's triad of hypotension, distended neck veins, and muffled heart sounds.
5. Melissa Smith came to the Emergency Department in the last week before her estimated date of confinement complaining of headaches, blurred vision, and vomiting. Suspecting PIH, the nurse should best respond to Melissa's complaints with which of the following statements?
- A. "The physician will probably want to admit you for observation."?
- B. "The physician will probably order bedrest at home."?
- C. "These are really dangerous signs."?
- D. "The physician will probably prescribe some medicine for you."?
Correct answer: B
Rationale: Pregnancy-induced hypertension (PIH) is a hypertensive disorder of pregnancy that can present after 20 weeks gestation. It is characterized by symptoms like edema, hypertension, and proteinuria, which can progress to conditions like pre-eclampsia and eclampsia. The best approach for a client with advanced PIH is rest, and home provides the most suitable environment for it. Hospitalization is not typically necessary for PIH unless there are severe complications. Medication alone is not the primary intervention for PIH; management often involves monitoring, rest, and close medical supervision. Therefore, advising bedrest at home is the most appropriate response to help manage PIH symptoms and prevent further complications, such as pre-eclampsia or eclampsia. The other options, like hospitalization for observation, emphasizing the danger of the signs without providing guidance, or assuming medication as the primary solution, are not in line with the standard management approach for PIH.
