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.

What is the qualitative method that attempts to construct the meaning of the lived experience of human phenomena?
- A. Phenomenology
- B. Ethnography
- C. Grounded theory
- D. Case study
Correct Answer: A
Rationale: Phenomenology is the qualitative method that attempts to construct the meaning of the lived experience of human phenomena. It focuses on understanding and describing individual experiences as they are lived and perceived by the person. Phenomenological research aims to uncover the essence or fundamental elements of a phenomenon by exploring the subjective experiences and perspectives of participants without imposing preconceived theories or assumptions. In essence, phenomenology seeks to capture the subjective reality and consciousness of individuals in their everyday lives.
Which of the following conditions does the nurse explain to the patient the contributory factor that slows uterine involution?
- A. Full bladder during labor
- B. Difficult birth
- C. Prolonged labor
- D. Infection during pregnancy
Correct Answer: C
Rationale: Prolonged labor is a condition in which labor lasts for an extended period, typically more than 20 hours for first-time mothers and more than 14 hours for experienced mothers. Prolonged labor can contribute to slowing down uterine involution because the prolonged pressure and strain on the uterus can affect its ability to return to its pre-pregnancy size and position. The prolonged contractions and stretching of the uterine muscles can hinder the normal process of uterine involution, leading to a delay in the uterus shrinking back to its non-pregnant state. Additionally, prolonged labor can increase the risk of postpartum complications such as excessive bleeding and infection, which can further impact uterine involution. Therefore, it is crucial for healthcare providers to monitor labor progress closely to prevent prolonged labor and its potential effects on uterine involution.
A postpartum client reports severe perineal pain and difficulty passing stools following a vaginal delivery. Which nursing intervention should be implemented?
- A. Administering a stool softener as ordered
- B. Encouraging the client to refrain from defecation until pain subsides
- C. Applying ice packs to the perineum for pain relief
- D. Providing education on proper perineal hygiene
Correct Answer: A
Rationale: Administering a stool softener as ordered is the most appropriate nursing intervention for a postpartum client experiencing severe perineal pain and difficulty passing stools following a vaginal delivery. Stool softeners help to soften the stool, making it easier for the client to pass without straining, which can exacerbate perineal pain. It is important to follow the healthcare provider's orders when administering medications to ensure proper dosing and effectiveness. Encouraging the client to refrain from defecation may lead to constipation and worsen the situation. Applying ice packs to the perineum can provide temporary pain relief, but addressing the underlying issue of constipation with a stool softener is more effective in the long term. Providing education on proper perineal hygiene is important for overall postpartum care, but addressing the immediate issue of constipation with a stool softener takes precedence in this scenario.
Cell-mediated immunity is NOT usually associated with what condition:
- A. Rejection of tissue graft
- B. Production of antibodies
- C. Skin hypersensitivity reaction
- D. Surveying for malignant cells
Correct Answer: B
Rationale: Cell-mediated immunity is a type of immune response that involves the activation of cytotoxic T cells and other immune cells to directly target and destroy infected or abnormal cells. It does not involve the production of antibodies, which are the primary component of humoral immunity. Antibodies are produced by B cells and are responsible for targeting extracellular pathogens such as bacteria and viruses. In contrast, cell-mediated immunity is more focused on targeting intracellular pathogens, cancerous cells, and other cells that have been compromised. So, production of antibodies is not usually associated with cell-mediated immunity.
A patient presents with sudden-onset severe headache, vomiting, and altered mental status. Imaging reveals a hyperdense lesion within the brain parenchyma, suggestive of acute bleeding. Which of the following neurological conditions is most likely responsible for these symptoms?
- A. Ischemic stroke
- B. Subdural hematoma
- C. Intracerebral hemorrhage
- D. Subarachnoid hemorrhage
Correct Answer: C
Rationale: Intracerebral hemorrhage is characterized by bleeding directly into the brain parenchyma, leading to the sudden onset of severe headache, vomiting, altered mental status, and neurological deficits. The hyperdense lesion seen on imaging is caused by the presence of blood within the brain tissue. This condition is often associated with hypertension and can be life-threatening if not promptly diagnosed and managed. Subdural hematoma is an accumulation of blood between the brain and its outermost covering (dura mater), typically presenting with a slower onset of symptoms compared to intracerebral hemorrhage. Subarachnoid hemorrhage involves bleeding into the space between the arachnoid membrane and the pia mater (subarachnoid space), commonly caused by the rupture of an aneurysm. Ischemic stroke results from the blockage of a blood vessel supplying the brain, leading to a lack of oxygen and nutrients to
