The MAIN function of surfactant factor is to
- A. Prevent alveoli of the lungs from collapsing
- B. Initiate breathing of the neonate at birth
- C. Enhance maturity of respiratory centre in the brain
- D. Regulate breathing immediately the baby is born
Correct Answer: A
Rationale: The correct answer is A: Prevent alveoli of the lungs from collapsing. Surfactant reduces surface tension in the alveoli, preventing them from collapsing during exhalation and maintaining lung compliance. B, C, and D are incorrect because surfactant primarily affects lung mechanics, not the initiation of breathing, maturity of the respiratory center, or immediate regulation of breathing upon birth.

Which one of the following clinical features indicates neonatal intracranial injury?
- A. An oedematous swelling on the newborn’s scalp that resolves in 48 hours
- B. Notable bleeding between the epicranial aponeurosis & the periosteum
- C. Evidence of excessive molding or abnormal stretching of the fetal head
- D. Peripheral cyanosis as noted by the midwife on the neonate’s peripheries
Correct Answer: C
Rationale: Rationale for choice C:
1. Excessive molding or abnormal stretching of the fetal head can indicate neonatal intracranial injury due to the trauma during birth.
2. This feature suggests possible compression or trauma to the baby's head during delivery.
3. It may lead to intracranial hemorrhage or other injuries, requiring close monitoring and medical intervention.
Summary of other choices:
A. An oedematous swelling resolving in 48 hours is likely a normal finding (cephalohematoma) and not specific to intracranial injury.
B. Notable bleeding between the epicranial aponeurosis & periosteum may indicate cephalohematoma or caput succedaneum, not necessarily intracranial injury.
D. Peripheral cyanosis is related to oxygenation and circulation, not specific to intracranial injury.
A client diagnosed with gestational diabetes at 24 weeks is scheduled for ANC care every
- A. Weekly up to 28 weeks
- B. Two weekly up to 28 weeks
- C. Four weekly up to 28 weeks
- D. Three weekly up to 28 weeks
Correct Answer: C
Rationale: The correct answer is C: Four weekly up to 28 weeks. Gestational diabetes requires close monitoring of blood sugar levels and fetal well-being. ANC care every four weeks up to 28 weeks ensures proper management and early detection of any complications. Weekly or two weekly visits (options A and B) may be too frequent and unnecessary at this stage unless there are specific concerns. Three weekly visits (option D) may not provide adequate monitoring intervals. Therefore, option C is the most appropriate choice for the optimal management of gestational diabetes at this stage of pregnancy.
The AGACNP knows that treatment for this likely will include
- A. Observation
- B. Hyperextension casting
- C. Jewett brace
- D. Surgical intervention
Correct Answer: B
Rationale: The correct answer is B: Hyperextension casting. The AGACNP knows that this treatment is appropriate for a condition that requires immobilization and support while allowing controlled movement. Hyperextension casting provides stability and support while promoting healing. Observation (A) would not provide adequate treatment for a condition requiring immobilization. Jewett brace (C) is typically used for spinal fractures, not for conditions that require hyperextension casting. Surgical intervention (D) would be considered if conservative measures like casting have failed.
A patient admitted for management of sepsis is critically ill and wants to talk with a hospital representative about donating her organs if she dies. She has a fairly complex medical history that includes traumatic brain injury, breast cancer, and dialysis-dependent renal failure. The patient is advised that she is ineligible to donate due to her
- A. Renal failure
- B. Traumatic brain injury
- C. Gram negative infection
- D. Breast cancer
Correct Answer: C
Rationale: The correct answer is C: Gram negative infection. In sepsis, especially with a Gram negative infection, organ donation may pose a risk of transmitting the infection to the recipient. This can be life-threatening for the organ recipient. Renal failure (choice A), traumatic brain injury (choice B), and breast cancer (choice D) are not direct contraindications to organ donation. Renal failure may limit the suitability of certain organs, but it does not automatically disqualify a patient from donating other organs. Traumatic brain injury may impact brain donation but does not rule out other organ donation. Breast cancer may affect eligibility for certain organs but does not universally disqualify a patient from organ donation.
In eclampsia, violent contraction and relaxation of the whole body occurs in
- A. Clonic stage
- B. Coma stage
- C. Premonitory stage
- D. Tonic stage
Correct Answer: A
Rationale: The correct answer is A: Clonic stage. In eclampsia, the clonic stage is characterized by violent contraction and relaxation of the whole body due to generalized seizures. During this stage, rhythmic jerking movements occur. The other choices are incorrect because:
B: Coma stage - In this stage, the individual is unconscious and not experiencing violent body movements.
C: Premonitory stage - This stage includes warning signs like headache and visual disturbances, but not the violent body movements seen in eclampsia.
D: Tonic stage - This stage involves sustained muscle contractions without relaxation, unlike the alternating contraction and relaxation seen in the clonic stage of eclampsia.
