A patient presents with acute knee pain and swelling following a twisting injury during sports activity. Physical examination reveals joint effusion and tenderness along the joint line. Which structure is most likely injured in this scenario?
- A. Anterior cruciate ligament (ACL)
- B. Medial collateral ligament (MCL)
- C. Meniscus
- D. Patellar tendon
Correct Answer: C
Rationale: The scenario described is suggestive of a meniscus injury. A twisting injury during sports activity leading to acute knee pain and swelling, accompanied by joint effusion and tenderness along the joint line, is commonly associated with meniscus tears. The meniscus is a C-shaped cartilage structure located between the femur and tibia in the knee joint, providing cushioning and stability. The symptoms of a meniscus tear typically include pain, swelling, joint line tenderness, and sometimes mechanical symptoms like locking or clicking. Treatment may involve rest, physical therapy, or in some cases, surgery to repair or remove the torn meniscus.

In as much as the research may have some risks on the part of the subject who is 21 years old, Nurse Carmi must assure the subject of her anonymity, confidentiality and respect for her human rights. ONE ABSOLUTE WAY is to get an informed and written consent from whom?
- A. Parents
- B. Husband
- C. Guardians
- D. Subject herself Situation
Correct Answer: D
Rationale: In research involving adults who are capable of providing informed consent, such as a 21-year-old subject, the absolute way to ensure autonomy and respect for the individual's rights is to obtain informed and written consent directly from the subject herself. The subject's autonomy and right to self-determination should be respected, and obtaining consent directly from the subject ensures that they are fully informed about the research, its risks, benefits, and their rights regarding anonymity and confidentiality. In this case, Nurse Carmi must explain the research process clearly to the 21-year-old subject, obtain her informed consent in writing, and ensure that her anonymity, confidentiality, and human rights are protected throughout the study.
One of the post-caesarian patients has a private duty nurse and is responsible for providing holistic care to her patient during the shift. What modality of nursing care is implemented?
- A. Primary
- B. Total care
- C. Team
- D. Functional
Correct Answer: B
Rationale: Total care nursing is a nursing care delivery model where one nurse is assigned to provide comprehensive care to a patient for an entire shift. In this case, the private duty nurse is providing holistic care to the post-caesarian patient during the shift, which aligns with the principles of total care nursing. This approach allows the nurse to focus on the individual needs of the patient and provide all aspects of care, promoting continuity and personalized attention. Total care nursing ensures that the patient receives consistent and dedicated care from the same nurse, enhancing the patient's overall experience and outcomes.
A patient presents with redness, pain, and photophobia in the left eye. Slit-lamp examination reveals ciliary injection, corneal edema, and a mid-dilated pupil with fixed reaction to light. Which of the following conditions is most likely responsible for this presentation?
- A. Anterior uveitis
- B. Acute angle-closure glaucoma
- C. Endophthalmitis
- D. Corneal abrasion
Correct Answer: A
Rationale: The presentation described in the question is most consistent with anterior uveitis. Anterior uveitis, also known as iritis, is characterized by redness, pain, and photophobia in the affected eye. Slit-lamp examination typically reveals ciliary injection (reddening of the conjunctiva and episclera), corneal edema, and a mid-dilated pupil with a fixed reaction to light (miosis). This occurs due to inflammation within the anterior chamber of the eye involving the iris and ciliary body.
A patient presents with watery diarrhea, abdominal cramps, and nausea after consuming contaminated water from a stream during a camping trip. Laboratory tests reveal oocysts in the stool sample. Which of the following parasites is most likely responsible for this infection?
- A. Giardia lamblia
- B. Entamoeba histolytica
- C. Cryptosporidium parvum
- D. Cyclospora cayetanensis
Correct Answer: C
Rationale: The patient is likely infected with Cryptosporidium parvum based on the symptoms of watery diarrhea, abdominal cramps, and nausea after consuming contaminated water. Cryptosporidium is a protozoan parasite that can be transmitted through contaminated water sources, such as streams. Laboratory tests revealing oocysts in the stool sample further support the diagnosis of Cryptosporidium infection, as these oocysts are characteristic of this parasite. Giardia lamblia is another common protozoan parasite that can cause similar symptoms but is usually associated with more foul-smelling, greasy diarrhea. Entamoeba histolytica causes amoebic dysentery, which presents with bloody diarrhea and abdominal pain. Cyclospora cayetanensis also causes watery diarrhea, but it is usually associated with foodborne outbreaks rather than waterborne transmission.
Which of the following are essential components of informed consent? I. explanation of the procedure and alternatives to the procedure II. discussion of potential risks and benefits of the procedure III. confirmation that the patient understands the risks, benefits, and any alterations
- A. I, III
- B. II, III
- C. I, II
- D. I, II, III
Correct Answer: D
Rationale: All of the components -explanation of the procedure and alternatives to the procedure (I), discussion of potential risks and benefits of the procedure (II), and confirmation that the patient understands the risks, benefits, and any alterations (III) -are essential parts of informed consent. Providing information about the procedure and its alternatives, disclosing potential risks and benefits, and ensuring that the patient comprehends this information are crucial to obtaining valid informed consent prior to any medical procedure.
