Correct Answer: B

Rationale: The correct answer is B because disclosing a patient's HIV status to family members violates the patient's right to privacy and confidentiality. Patient confidentiality is a fundamental aspect of the Patient's Bill of Rights, ensuring that personal health information is protected. The other choices (A, C, D) do not directly violate the Patient's Bill of Rights. Choice A relates to transparency in billing, choice C is about honesty in communication, and choice D is about timely communication with the physician, all of which are in line with patient rights and quality care.

Correct Answer: C

Rationale: The correct answer is C: Macrophages. Macrophages are antigen-presenting cells that engulf pathogens and present their antigens to T cells, initiating an immune response. They express major histocompatibility complex (MHC) molecules necessary for T cell recognition. B cells also present antigens but primarily to B cells for antibody production. NK cells are involved in killing infected cells, not antigen presentation. Eosinophils are mainly involved in allergic responses and defense against parasites, not antigen presentation.

Correct Answer: C

Rationale: The correct answer is C because checking the completeness of the charting by doctors and nurses ensures that all necessary information is accurately documented, facilitating proper patient care and treatment. This step helps identify any missing or incorrect information that may impact patient safety. A: Storing the charts in respective shelves is a routine task that does not involve verifying the accuracy or completeness of the information. B: Separating medico-legal charts is important but does not directly address the completeness of charting by doctors and nurses. D: Binding the charts immediately is not necessary before ensuring the completeness and accuracy of the information documented.

Correct Answer: B

Rationale: The correct answer is B: Prevents postpartum hemorrhage. Methylergonovine maleate is a uterotonic medication used to prevent and treat postpartum hemorrhage by causing strong uterine contractions, which help to control bleeding after delivery. It is not used to reduce lochia drainage (choice A), decrease uterine contractions (choice C), or maintain normal blood pressure (choice D). By understanding the pharmacological action of methylergonovine maleate in preventing postpartum hemorrhage, we can confidently select choice B as the correct answer.

Genetic factors can impact an individual's susceptibility to certain diseases and conditions. 3. Health beliefs and practices may be influenced by knowledge of one's genetic predispositions. 4. Family structure, socioeconomic status, and living situation are external variables that may influence health but are not inherent to the individual like genetics.
