K. W. is a 50-year-old woman who presents for surgical resection of the liver for treatment of metastatic colon cancer. Preoperatively, the surgeon tells her that he is planning to remove 50 to 75 of her liver. The patient is concerned that she will not be able to recover normal liver function with that much removed. The AGACNP counsels her that
- A. Such a high-volume resection is utilized only in people with markedly compromised hepatic function
- B. Major regeneration occurs within 10 days, and the process is complete by 5 weeks
- C. Liver function will probably recover to 50% baseline, but that is enough for normal function
- D. Up to 95% of the liver can be removed without any apparent consequence to the patient
Correct Answer: A
Rationale: The correct answer is A because high-volume liver resection is typically performed in individuals with significantly compromised hepatic function to ensure adequate liver remnant. Removing 50 to 75% of the liver in a patient with metastatic colon cancer may be necessary for tumor clearance but carries risks due to potential impairment of liver function postoperatively. Choices B and C provide inaccurate information regarding the timeline and extent of liver regeneration following resection. Choice D is incorrect as removing up to 95% of the liver would lead to severe consequences, such as liver failure. Hence, option A is the most appropriate advice given the patient's situation.

Presence of severe epigastric pain in preeclampsia is associated with hyperacidity.
- A. TRUE
- B. FALSE
- C. -
- D. -
Correct Answer: B
Rationale: The correct answer is B: FALSE. In preeclampsia, epigastric pain is typically associated with liver and/or HELLP syndrome, not hyperacidity. Hyperacidity is more commonly seen in conditions like gastritis or peptic ulcers. Therefore, severe epigastric pain in preeclampsia is not related to hyperacidity. Other choices are not applicable as they do not provide relevant information to the question.
Justin F. is seen in the emergency department with an 8-cm jagged laceration on the dorsal surface of his right forearm. He says he was working with his brother-in-law yesterday morning building a deck on the back of his home. A pile of wooden planks fell on top of him, and he sustained a variety of cuts and superficial injuries. He cleaned the wound with soap and water but didnt want to go to the emergency room because he didnt want to risk being in the waiting room for hours. He wrapped up his arm and went back to work, and then took a normal shower and went to bed last night. This morning the cut on his arm was still flapping open, and he realized he needed sutures. The appropriate management of this patient includes
- A. Proper cleansing and covering of the laceration, along with antibiotic therapy
- B. Local anesthesia, cleansing, and wound exploration for foreign bodies
- C. Local anesthesia, cleansing, and suture repair
- D. Cleansing, covering, antibiotic therapy, and tetanus prophylaxis
Correct Answer: C
Rationale: The correct answer is C: Local anesthesia, cleansing, and suture repair.
1. Local anesthesia is needed to minimize pain during the procedure.
2. Cleansing is crucial to remove contaminants and reduce the risk of infection.
3. Suture repair is necessary for a jagged laceration of this size to promote proper wound healing and minimize scarring.
Summary of other choices:
A: Antibiotic therapy is not routinely needed for clean lacerations, and covering alone may not provide adequate wound closure.
B: While wound exploration for foreign bodies is important, it is not the immediate priority for this patient with an open, flapping laceration.
D: While cleansing, covering, and tetanus prophylaxis are important, antibiotic therapy is not routinely needed for clean lacerations.
Arched back and tightly clenched teeth are among the features of which stage of eclampsia:
- A. Clonic
- B. Tonic
- C. Premonitory
- D. Coma
Correct Answer: B
Rationale: The correct answer is B: Tonic. During the tonic stage of eclampsia, the muscles go into a prolonged contraction leading to an arched back and tightly clenched teeth. This is due to sustained muscle rigidity. In contrast, the clonic stage involves rhythmic muscle contractions and relaxations, not sustained rigidity. The premonitory stage is characterized by warning signs like headaches and visual disturbances, not specific physical postures. Coma is a severe stage of unconsciousness, not associated with specific physical postures or muscle rigidity seen in the tonic stage of eclampsia.
Effects of pregnancy on malaria are
- A. Development of severe anaemia and severe jaundice
- B. Blood smear is always positive and severe anaemia
- C. Therapy limitation and few parasites in severe cases
- D. Loss of pregnancy and severe condition in few parasites
Correct Answer: A
Rationale: Step-by-step rationale for why choice A is correct:
1. Pregnancy can lead to severe anaemia due to increased demand for iron and folate.
2. Pregnancy-induced physiological changes can exacerbate malaria-related anaemia.
3. Severe jaundice may occur in pregnant women with malaria due to liver dysfunction.
4. These effects are common during pregnancy and can worsen with malaria infection.
Summary of why other choices are incorrect:
- Choice B: Blood smear positivity is not always guaranteed in malaria, and severe anaemia is not the only effect.
- Choice C: Therapy limitations can occur, but the presence of few parasites in severe cases is not a defining feature.
- Choice D: Loss of pregnancy can happen, but it is not a universal effect of malaria during pregnancy, and severity is not based on parasite count alone.
Delivery of the head in a complete breech presentation is usually accomplished through
- A. Lovset maneuver
- B. Mauriceau-Smellie-Veit
- C. Burns Marshall method
- D. Gentle traction of the neck
Correct Answer: B
Rationale: The correct answer is B: Mauriceau-Smellie-Veit. This method involves flexing the hips, extending the thighs, and applying suprapubic pressure to deliver the head in a complete breech presentation. This technique helps to avoid hyperextension of the neck and potential spinal cord injury. The Lovset maneuver (A) is used for delivering the arms in a breech presentation. The Burns Marshall method (C) involves performing an episiotomy and delivering the baby by flexion and traction on the legs. Gentle traction of the neck (D) is not recommended as it can cause spinal cord injury. Mauriceau-Smellie-Veit is the preferred method for safe delivery of the head in a complete breech presentation.
