The main feature in the initial stage of shock is
- A. Cyanosis
- B. Tachycardia
- C. Sweat beads
- D. Hypotension
Correct Answer: B
Rationale: The correct answer is B: Tachycardia. In the initial stage of shock, the body tries to compensate for decreased perfusion by increasing heart rate to maintain blood flow to vital organs. Cyanosis (A) is a late sign of shock due to inadequate oxygenation. Sweat beads (C) are a non-specific response and not a defining feature of shock. Hypotension (D) typically occurs in the later stages of shock as the body's compensatory mechanisms start to fail. Tachycardia is the earliest and most consistent sign of shock, reflecting the body's attempt to maintain cardiac output.

A condition of trial of scar is
- A. Estimated fetal weight of less than 3600g
- B. Availability of a level one hospital nearby
- C. Not more than two previous caesarean section scars
- D. An adequate pelvis with true conjugate 10.5cm
Correct Answer: C
Rationale: Rationale for Correct Answer (C): A trial of scar is indicated when a woman has had no more than two previous caesarean sections. This is because the risk of uterine rupture increases with each subsequent caesarean section due to scar tissue weakening. Limiting the number of previous scars reduces this risk. Therefore, option C is correct.
Summary of Incorrect Choices:
A: Estimated fetal weight is not a determining factor for a trial of scar.
B: Availability of a level one hospital nearby is important for emergency situations but not a criteria for trial of scar.
D: Adequate pelvis with true conjugate 10.5cm is important for vaginal delivery but not a specific requirement for a trial of scar.
A client is declared fit for a vaginal birth after cesarean section if
- A. Her previous C/S was due to cephalopelvic disproportion
- B. The current pregnancy is confirmed a multiple pregnancy
- C. Previous delivery was via cesarean section
- D. Previous delivery was via spontaneous vertex delivery
Correct Answer: D
Rationale: The correct answer is D because a client is declared fit for a vaginal birth after cesarean section if their previous delivery was via spontaneous vertex delivery. This indicates that the client has successfully given birth vaginally before, reducing the risk associated with a vaginal birth after cesarean section.
A, B, and C are incorrect:
A: Cephalopelvic disproportion was the reason for the previous C/S, indicating potential difficulty in vaginal delivery.
B: Confirmation of a multiple pregnancy does not impact the client's eligibility for a vaginal birth after cesarean section.
C: Previous cesarean section does not necessarily mean the client is fit for a vaginal birth after cesarean section.
How can Braxton Hicks contractions be differentiated from true labor?
- A. By timing
- B. By intensity
- C. By duration
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D - All of the above. Braxton Hicks contractions can be differentiated from true labor by timing, intensity, and duration. Timing refers to the regularity of contractions, intensity relates to the strength of contractions, and duration indicates how long contractions last. By considering all three factors together, one can determine whether contractions are Braxton Hicks (practice contractions) or true labor contractions. Choices A, B, and C alone provide only partial information, which may lead to misinterpretation. Therefore, choosing all three factors collectively (D) is essential for accurate differentiation.
Flexion-distraction injuries of the thoracolumbar spine are most commonly caused by
- A. Blunt trauma
- B. Rotational injury
- C. Seat belts
- D. Gunshot wounds
Correct Answer: B
Rationale: The correct answer is B: Rotational injury. Flexion-distraction injuries of the thoracolumbar spine are often caused by rotational forces that occur during accidents such as motor vehicle collisions or falls. These forces lead to the spine being twisted, causing separation of the vertebrae. Blunt trauma (A) can cause various spinal injuries but is not specific to flexion-distraction injuries. Seat belts (C) are designed to prevent spinal injuries by restraining the body during a collision. Gunshot wounds (D) can cause spinal cord injuries but are not commonly associated with flexion-distraction injuries of the thoracolumbar spine.
Deep transverse arrest is
- A. Where flexion is always well maintained.
- B. Caused by strong uterine contractions throughout labor.
- C. Caused by a sacrum that is well curved.
- D. Where the level of the occiput and the sinciput is the same.
Correct Answer: D
Rationale: The correct answer is D because deep transverse arrest occurs when the level of the occiput and the sinciput is the same, leading to a failure of descent of the fetal head through the pelvis. This alignment issue hinders the progress of labor despite adequate contractions.
A: Incorrect. Flexion being well maintained is not a defining characteristic of deep transverse arrest.
B: Incorrect. While strong uterine contractions can contribute to labor challenges, deep transverse arrest is specifically related to the alignment of the fetal head.
C: Incorrect. The curvature of the sacrum is not directly related to deep transverse arrest.
