In myelodysplastic syndromes, the primary indications for splenectomy include
- A. Major hemolysis unresponsive to medical management
- B. Severe symptoms of massive splenomegaly
- C. Sustained leukocyte elevation above 30,000 cells/µL
- D. Portal hypertension
Correct Answer: C
Rationale: The correct answer is C. In myelodysplastic syndromes, splenectomy is indicated for sustained leukocyte elevation above 30,000 cells/µL to manage symptomatic splenomegaly and cytopenias. This is because an enlarged spleen can sequester and destroy blood cells, leading to low blood cell counts. Choices A, B, and D are incorrect as splenectomy is not typically indicated for major hemolysis unresponsive to medical management, severe symptoms of massive splenomegaly, or portal hypertension in the context of myelodysplastic syndromes.

Prior to taking a patient for an emergency cesarean section, it is MOST important to assess that:
- A. A signed informed consent has been given
- B. A Foley’s catheter has been inserted
- C. An intravenous line has been started
- D. The perineal area has been shaved adequately
Correct Answer: C
Rationale: The correct answer is C because establishing an intravenous line is essential for immediate access to administer fluids, medications, and blood products during the emergency cesarean section. This step ensures that the patient's vital signs can be supported, and any emergent interventions can be readily delivered.
A: While informed consent is important, in an emergency situation, the priority is to ensure the patient's immediate medical needs are met.
B: Inserting a Foley's catheter may be necessary during the procedure, but it is not the most critical assessment prior to the cesarean section.
D: Shaving the perineal area is not a priority in an emergency situation and may be done during the preparation for surgery.
Neonatal injury to nerve roots C8 & T1 causes one of the following
- A. Klumpke’s palsy
- B. Erb’s palsy
- C. Phrenic injury
- D. Radial palsy
Correct Answer: A
Rationale: Neonatal injury to nerve roots C8 & T1 leads to Klumpke's palsy due to damage to the lower brachial plexus. This results in weakness of the hand and forearm muscles. Erb's palsy is from injury to C5-C6 roots causing upper brachial plexus damage. Phrenic injury affects the diaphragm due to C3-C5 roots. Radial palsy involves the radial nerve, typically from injury at the spiral groove of the humerus. Therefore, the correct answer is A as it directly correlates with the specific nerve roots affected in Klumpke's palsy.
The baby dies immediately after birth due to the presence of
- A. Pulmonary stenosis
- B. Aortic coarctation
- C. Truncus arteriosus
- D. Ductus arteriosus
Correct Answer: C
Rationale: The correct answer is C: Truncus arteriosus. In this congenital heart defect, a single large blood vessel arises from the heart instead of the normal two separate vessels (aorta and pulmonary artery). This results in mixing of oxygenated and deoxygenated blood, leading to severe cyanosis and inadequate oxygen supply to the body. This condition is incompatible with life, causing immediate death after birth.
A: Pulmonary stenosis and B: Aortic coarctation are also congenital heart defects but do not typically result in immediate death after birth. Pulmonary stenosis obstructs blood flow to the lungs, while aortic coarctation causes narrowing of the aorta.
D: Ductus arteriosus is a normal fetal blood vessel that connects the pulmonary artery and the aorta but usually closes shortly after birth. Failure of closure can lead to health issues, but it is not typically a cause of immediate death after birth.
Neoadjuvant chemotherapy treatment for cancer is given to facilitate surgical resection. When the outcomes of cancer therapies are evaluated, the terms complete response and partial response often are used. Partial response means that
- A. 50% of the patients treated with a given regimen demonstrate remission
- B. 50% of the patients treated survive to the 5-year point
- C. The tumor mass has reduced by > 50%
- D. In 50% of cases, the tumor converts from unresectable to resectable
Correct Answer: D
Rationale: The correct answer is D because in the context of neoadjuvant chemotherapy, a partial response means converting an unresectable tumor to a resectable one. This is crucial as it allows for successful surgical removal of the tumor. Choices A, B, and C do not accurately define partial response in the context of cancer therapy. A, stating 50% of patients demonstrating remission, is not specific to the change in resectability. B, mentioning 50% survival at 5 years, is more related to overall survival rather than the response to treatment. C, stating a reduction in tumor mass by >50%, does not necessarily imply a change in resectability status. Therefore, option D is the most appropriate definition of partial response in the given scenario.
When caring for a mother following an assisted vaginal delivery, it’s MOST important to remember that
- A. A vacuum extractor is safer than forceps because it causes less trauma to the baby & the mother’s perineum
- B. The baby will develop a cephalhematoma as a result of the instrumentation which is a normal expected outcome
- C. The use of instruments during the birth process is a fairly rare occurrence for women
- D. Additional nursing interventions are needed to ensure an uncomplicated postpartum
Correct Answer: D
Rationale: The correct answer is D because additional nursing interventions are necessary to ensure an uncomplicated postpartum period. After an assisted vaginal delivery, the mother may experience increased pain, perineal trauma, and a higher risk of postpartum hemorrhage. Nursing interventions such as pain management, wound care, monitoring for signs of infection, and emotional support are crucial for the mother's recovery.
A is incorrect because both vacuum extractors and forceps can cause trauma to the baby and mother's perineum, and the safety of one over the other depends on various factors.
B is incorrect as the development of a cephalhematoma is not a normal expected outcome of assisted vaginal delivery and should be monitored and managed appropriately if it occurs.
C is incorrect as the use of instruments during childbirth, while not as common as spontaneous vaginal deliveries, is not rare and can be necessary in certain situations to ensure the safety of the mother and baby.
