Teratogenic causes of congenital abnormalities include
- A. Medical conditions and pesticides
- B. Prescription drugs and chromosomes
- C. Radiation and substances of abuse
- D. Disordered genes and medical conditions
Correct Answer: C
Rationale: The correct answer is C because radiation and substances of abuse are known teratogenic causes of congenital abnormalities. Radiation exposure can lead to genetic mutations and developmental issues in the fetus. Substances of abuse like alcohol, tobacco, and illicit drugs can also negatively impact fetal development.
A: Medical conditions and pesticides may have negative effects on pregnancy outcomes, but they are not typically classified as teratogenic causes of congenital abnormalities.
B: Prescription drugs can be teratogenic in some cases, but not all prescription drugs have harmful effects on fetal development. Chromosomes are not typically considered teratogenic causes.
D: Disordered genes can lead to congenital abnormalities, but they are not classified as teratogenic causes. Medical conditions are not universally teratogenic.

Delivery of breech with an extended head is accomplished through
- A. Burns Marshall maneuver
- B. Lovset maneuver
- C. Mauriceau-Smellie-Veit
- D. McRobert’s maneuver
Correct Answer: C
Rationale: The correct answer is C: Mauriceau-Smellie-Veit maneuver for delivery of breech with an extended head. This maneuver involves flexing the head while still in the vagina to allow for easier delivery. The Burns Marshall maneuver (A) is for impacted fetal shoulders, Lovset maneuver (B) is for shoulder dystocia, and McRobert's maneuver (D) is for shoulder dystocia as well. The Mauriceau-Smellie-Veit maneuver is specifically designed for delivering a breech with an extended head, making it the correct choice in this scenario.
A neonate whose birth weight is 1201 grams is regarded as
- A. Genetically small neonate
- B. Low birth weight neonate
- C. Very low birth weight neonate
- D. Extremely low birth weight neonate
Correct Answer: C
Rationale: The correct answer is C: Very low birth weight neonate. This designation is given to infants whose birth weight is less than 1500 grams. In this case, the neonate's weight of 1201 grams falls within the criteria for very low birth weight. Choice A is incorrect because being genetically small does not necessarily equate to low birth weight. Choice B is incorrect as low birth weight typically refers to infants weighing between 1500-2499 grams. Choice D is incorrect as extremely low birth weight pertains to infants weighing less than 1000 grams.
During neonatal resuscitation, dry wiping is aimed at
- A. Preventing hypothermia and facilitating tactile stimulation
- B. Preventing hemorrhage and clearing of the airway
- C. Preventing infection and facilitating tactile stimulation
- D. Improving the appearance and preventing infection
Correct Answer: A
Rationale: The correct answer is A: Preventing hypothermia and facilitating tactile stimulation. Dry wiping during neonatal resuscitation helps prevent hypothermia by removing wetness from the baby's skin. It also facilitates tactile stimulation, which can help stimulate the baby's breathing.
Summary:
B: Preventing hemorrhage and clearing of the airway - Dry wiping does not prevent hemorrhage or clear the airway directly.
C: Preventing infection and facilitating tactile stimulation - While dry wiping can help prevent infection, its primary aim during neonatal resuscitation is to prevent hypothermia.
D: Improving the appearance and preventing infection - Dry wiping is not done for cosmetic reasons; its main purpose is to prevent hypothermia.
Placenta praevia is also referred to as unavoidable haemorrhage because
- A. Bleeding results as the segment prepares for true labour
- B. Bleeding results from pathological processes of the placenta
- C. Bleeding always occurs after a gestation of 37 complete weeks
- D. Of the high morbidity and mortality rate to the mother and neonate
Correct Answer: D
Rationale: The correct answer is D because placenta praevia can lead to severe bleeding during childbirth, posing high risks to both the mother and the baby. This condition occurs when the placenta partially or completely covers the cervix, leading to bleeding as the cervix dilates during labor. Choice A is incorrect because bleeding in placenta praevia is not related to the segment preparing for labor. Choice B is incorrect as bleeding is primarily due to the abnormal placement of the placenta, not from pathological processes. Choice C is incorrect as bleeding can occur before 37 weeks in cases of placenta praevia.
The AGACNP is covering an internal medicine service and is paged by staff to see a patient who has just pulled out his ET tube. After the situation has been assessed, it is clear that the patient will go into respiratory failure and likely die if he is not reintubated. The patient is awake and alert and is adamant that he does not want to be reintubated. The AGACNP is concerned that there is not enough time to establish a DNRthe patient needs to be reintubated immediately and already is becoming obtunded. Which ethical principles are in conflict here?
- A. Veracity and beneficence
- B. Beneficence and nonmalfeasance
- C. Autonomy and beneficence
- D. Justice and autonomy
Correct Answer: C
Rationale: The correct answer is C: Autonomy and beneficence. Autonomy refers to the patient's right to make their own decisions regarding their healthcare. In this case, the patient is refusing reintubation, exercising his autonomy. However, beneficence, the duty to act in the patient's best interest, also comes into play as the patient's refusal could lead to respiratory failure and death. The conflict arises from balancing the patient's autonomy with the healthcare provider's duty to provide beneficial care.
Choices A, B, and D are incorrect because they do not accurately capture the ethical conflict present in the scenario. Veracity (A) refers to truthfulness, which is not the primary issue here. Nonmalfeasance (B) is the duty to do no harm, which is not directly relevant to the conflict between the patient's autonomy and the need for beneficial care. Justice (D) relates to fairness in resource allocation and is not the primary issue in this case.
