Which of the following definition MOST accurately describes meningomyelocele? It is _______.
- A. Spinal cord tumor containing nerve roots.
- B. Complete exposure of the spinal cord and meninges.
- C. Herniation of spinal cord, cerebro-spinal fluid and meninges into a sac.
- D. Sac formation containing meninges and spinal fluid.
Correct Answer: C
Rationale: Meningomyelocele is a type of neural tube defect where there is a protrusion of the spinal cord, cerebrospinal fluid, and meninges through a defect in the vertebrae, forming a sac on the surface of the back. This condition occurs during fetal development when the neural tube fails to close completely, leading to the exposure of the spinal cord and its coverings. This herniation can result in a range of neurological deficits and complications, requiring surgical repair shortly after birth to prevent further damage and infections.

A postpartum client presents with persistent, severe abdominal pain, distention, and absent bowel sounds. Which nursing action is most appropriate?
- A. Encouraging the client to ambulate to promote bowel function
- B. Providing a heating pad to alleviate abdominal discomfort
- C. Notifying the healthcare provider immediately
- D. Administering a laxative to promote bowel evacuation
Correct Answer: C
Rationale: The most appropriate nursing action in this situation is to notify the healthcare provider immediately. The symptoms the postpartum client is experiencing - persistent, severe abdominal pain, distention, and absent bowel sounds - are concerning and could indicate a serious underlying issue such as bowel obstruction or other complications. Prompt communication with the healthcare provider is crucial to ensure the client receives the necessary assessment, intervention, and treatment. Encouraging ambulation, providing a heating pad, or administering a laxative are not appropriate actions in this case without first consulting with the healthcare provider due to the severity and potential complexity of the client's symptoms.
A nurse is preparing to assist with a transurethral resection of the prostate (TURP) procedure for a patient with benign prostatic hyperplasia (BPH). What action should the nurse prioritize to prevent fluid overload during TURP?
- A. Monitoring the patient's serum electrolyte levels during the procedure
- B. Administering diuretic medications to the patient before the procedure
- C. Limiting the duration of irrigation fluid instillation during TURP
- D. Adjusting the irrigation fluid temperature to promote hemostasis
Correct Answer: C
Rationale: During a transurethral resection of the prostate (TURP), fluid irrigation is commonly used to distend the bladder and flush out tissue debris. However, it is important to prioritize preventing fluid overload in the patient. Limiting the duration of irrigation fluid instillation is a crucial action to prevent excessive fluid absorption and subsequent fluid overload. Prolonged irrigation may lead to an increased risk of fluid overload and electrolyte imbalances, which can result in serious complications such as hyponatremia and fluid volume excess. Monitoring the patient's serum electrolyte levels can be important, but limiting the duration of irrigation is a more immediate and proactive measure to prevent fluid overload. Administering diuretic medications before the procedure may not be appropriate without assessing the patient's specific fluid status and needs. Adjusting the irrigation fluid temperature, while important for hemostasis, does not directly
A woman in active labor is receiving intravenous antibiotics for group B streptococcus (GBS) prophylaxis. What maternal assessment finding indicates a potential adverse reaction to the antibiotics?
- A. Respiratory depression
- B. Urticaria and pruritus
- C. Hypertension
- D. Decreased uterine contractility
Correct Answer: B
Rationale: Urticaria (hives) and pruritus (itching) are common signs of an allergic reaction to antibiotics, including those used for GBS prophylaxis during labor. Other signs of an adverse reaction may include flushing, fever, chills, and anaphylaxis. It is important to monitor the woman closely for any signs of an allergic reaction and to intervene promptly if one occurs to ensure the safety of both the mother and the baby.
A client has undergone a lymph node biopsy. The nurse anticipates that the report will reveal which result if the client has Hodgkin's Lymphoma?
- A. Reed-Sternberg cells
- B. Philadelphia chromosome
- C. Epstein-barr virus
- D. Herpes simplex virus
Correct Answer: A
Rationale: Reed-Sternberg cells are large, abnormal lymphocytes that are characteristic of Hodgkin's Lymphoma. They are typically found in the affected lymph nodes of individuals with Hodgkin's Lymphoma when examined under a microscope. Identifying Reed-Sternberg cells in a lymph node biopsy is a key diagnostic feature of Hodgkin's Lymphoma. This distinguishes Hodgkin's Lymphoma from other types of lymphomas that do not have Reed-Sternberg cells.
A patient presents with gradual-onset memory loss, confusion, and difficulty with complex tasks such as managing finances and planning. Over time, the patient develops disorientation to time and place and requires assistance with activities of daily living. Which of the following neurological conditions is most likely responsible for these symptoms?
- A. Alzheimer's disease
- B. Parkinson's disease
- C. Huntington's disease
- D. Frontotemporal dementia
Correct Answer: A
Rationale: The patient's presentation of gradual-onset memory loss, confusion, difficulty with complex tasks, disorientation, and functional decline are all classic features of Alzheimer's disease. Alzheimer's disease is a progressive neurodegenerative disorder characterized by the accumulation of abnormal protein deposits in the brain, leading to widespread neuronal damage and cognitive decline. As the disease progresses, patients typically experience worsening memory loss, cognitive impairment, and deficits in activities of daily living, ultimately requiring full-time care and assistance. Other neurodegenerative diseases such as Parkinson's disease, Huntington's disease, and frontotemporal dementia may present with cognitive impairment and behavioral changes, but the specific constellation of symptoms described in the case is most indicative of Alzheimer's disease.
