An early sign of a ruptured uterus includes
- A. Maternal dehydration
- B. Maternal pyrexia >38˚C
- C. Maternal oliguria
- D. Failure of cervix to dilate
Correct Answer: D
Rationale: The correct answer is D. A ruptured uterus can lead to fetal distress and necessitate a cesarean section. Failure of the cervix to dilate is indicative of a potential uterine rupture, as the uterus may not be able to contract effectively due to the rupture. Maternal dehydration (A), pyrexia (B), and oliguria (C) are not specific signs of a ruptured uterus and may be present in various other conditions. Therefore, failure of the cervix to dilate is the most relevant early sign in this scenario.

The birth weight of a very low birth weight baby ranges between
- A. 1000-500 gm
- B. 500-1500 gm
- C. 1001-1500 gm
- D. 1500-2000 gm
Correct Answer: B
Rationale: The correct answer is B (500-1500 gm) because very low birth weight babies typically weigh less than 1500 grams at birth. This range encompasses the common weight range for these babies. Option A (1000-500 gm) is too narrow and excludes babies weighing below 500 grams. Option C (1001-1500 gm) is incorrect as it includes babies weighing over 1500 grams. Option D (1500-2000 gm) is incorrect as it includes babies above the typical weight range for very low birth weight babies.
The congenital abnormality of the respiratory tract, associated with abnormal apical position, is
- A. Laryngeal stridor
- B. Diaphragmatic hernia
- C. Choanal atresia
- D. Tracheo-bronchi fistula
Correct Answer: C
Rationale: The correct answer is C: Choanal atresia. The congenital abnormality of the respiratory tract with abnormal apical position is typically associated with choanal atresia, which is a blockage or narrowing of the back of the nasal passage. This condition can lead to respiratory distress in newborns due to difficulty breathing through the nose.
Explanation:
1. Laryngeal stridor (Choice A) is a high-pitched noise during breathing and is not typically associated with abnormal apical position.
2. Diaphragmatic hernia (Choice B) is a defect in the diaphragm that allows abdominal organs to move into the chest cavity, but it is not related to abnormal apical position.
3. Tracheo-bronchi fistula (Choice D) is an abnormal connection between the trachea and bronchi, which is not associated with abnormal apical position.
In summary, choanal atresia is the correct answer because it fits the description of
While reviewing the head CT scan of a patient following a motor vehicle accident, the AGACNP appreciates a crescent-shaped fluid collection. This most likely represents
- A. Acute subdural hematoma
- B. Acute epidural hematoma
- C. Acute uncal herniation
- D. Acute brainstem compression
Correct Answer: B
Rationale: The correct answer is B: Acute epidural hematoma. A crescent-shaped fluid collection seen on a head CT scan following trauma is indicative of an epidural hematoma, which typically occurs due to an arterial bleed between the dura mater and the skull. This collection appears biconvex due to the restriction of the hematoma by the dura mater and is often associated with a lucid interval followed by rapid deterioration.
Explanation for Incorrect Choices:
A: Acute subdural hematoma typically presents as a crescent-shaped collection but is located between the dura mater and arachnoid mater, not between the dura mater and skull as seen in epidural hematomas.
C: Acute uncal herniation involves displacement of the uncus of the temporal lobe, leading to compression of the brainstem, but it does not manifest as a crescent-shaped fluid collection.
D: Acute brainstem compression does not typically present as a distinct crescent-shaped
Achalasia is a risk factor for
- A. Squamous cell carcinoma
- B. Gastroesophageal reflux disease
- C. Esophageal atrophy
- D. Malabsorption syndromes
Correct Answer: B
Rationale: The correct answer is B: Gastroesophageal reflux disease (GERD). Achalasia is a motility disorder characterized by impaired esophageal peristalsis and lower esophageal sphincter relaxation. This dysfunction can lead to stagnant food in the esophagus, causing regurgitation and increased intra-esophageal pressure, which can trigger GERD. Squamous cell carcinoma (choice A) is not directly linked to achalasia. Esophageal atrophy (choice C) is not a typical consequence of achalasia. Malabsorption syndromes (choice D) are not directly associated with achalasia.
Classical caesarean section is indicated for
- A. An anteriorly situated placenta praevia
- B. A posteriorly situated placenta praevia
- C. A gestation of more than 32 weeks
- D. Aesthetic purpose on maternal request
Correct Answer: A
Rationale: The correct answer is A because in cases of anteriorly situated placenta praevia, where the placenta partially or completely covers the cervix, a classical caesarean section is indicated to prevent severe bleeding during delivery. For choice B, a posteriorly situated placenta praevia does not necessitate a classical caesarean section. Choice C, gestation of more than 32 weeks, does not specifically indicate the need for a classical caesarean section. Choice D, aesthetic purpose on maternal request, is not a valid medical indication for a classical caesarean section.
