Inadequate levels of surfactant in a neonate leads to a condition referred to as
- A. Meconium aspiration syndrome
- B. Intranatal pneumonia
- C. Respiratory distress syndrome
- D. Congenital pneumothorax
Correct Answer: C
Rationale: The correct answer is C: Respiratory distress syndrome. Surfactant is essential for reducing surface tension in the alveoli, preventing their collapse. Inadequate levels of surfactant in a neonate result in respiratory distress syndrome. Meconium aspiration syndrome (A) is due to inhalation of meconium by the neonate. Intranatal pneumonia (B) is an infection acquired during birth. Congenital pneumothorax (D) is the presence of air in the pleural space, not directly related to surfactant levels.

Which of the following statements is true with respect to adrenal tumors that produce gender symptoms?
- A. Feminizing adrenal tumors are almost always carcinomas
- B. Feminizing adrenal tumors are the most common type of adrenal tumor
- C. Virilizing tumors in women are most often localized to the adrenal cortex
- D. Virilizing adrenal tumors are more likely to be malignant in children
Correct Answer: D
Rationale: The correct answer is D because virilizing adrenal tumors are more likely to be malignant in children. This is due to the fact that virilizing tumors can be associated with conditions like adrenocortical carcinoma, which is a malignant tumor. In contrast, feminizing adrenal tumors are not always carcinomas (choice A) and are not the most common type of adrenal tumor (choice B). Additionally, virilizing tumors in women can be localized to different parts of the adrenal gland, not just the cortex (choice C). Therefore, choice D is the most accurate statement among the options provided.
K. T. presents for a routine wellness examination, and the review of systems is significant only for a markedly decreased capacity for intake and a vague sense of nausea after eating. K. T. denies any other symptoms the remainder of the GI review of systems is negative. His medical history is significant for complicated peptic ulcer disease that finally required resection for a perforated ulcer. The AGACNP advises the patient that
- A. He will need endoscopy to evaluate the problem
- B. Chronic gastroparesis is a known complication of ulcer surgery
- C. Medication is unlikely to help, and he may need another surgery
- D. His symptoms occur in 5 to 10% of people after ulcer surgery
Correct Answer: D
Rationale: The correct answer is D: His symptoms occur in 5 to 10% of people after ulcer surgery. This is the correct answer because the patient's symptoms of decreased capacity for intake and nausea after eating are common post-operative complications following ulcer surgery. By stating this fact to the patient, the AGACNP is providing reassurance that these symptoms are not unusual.
Explanation for why the other choices are incorrect:
A: Endoscopy is not necessary at this point since the symptoms described by the patient are known post-operative complications and do not indicate an urgent need for endoscopy.
B: While gastroparesis can be a complication of ulcer surgery, there is no information in the case to suggest that the patient has chronic gastroparesis.
C: Jumping to the conclusion that medication is unlikely to help and another surgery may be needed is premature and not supported by the information provided in the case.
Excessive traction and twisting of the neck during delivery of the shoulders in SVD could lead to
- A. Erb’s palsy
- B. Radial palsy
- C. Torticollis
- D. Ecchymosis
Correct Answer: A
Rationale: The correct answer is A: Erb’s palsy. Excessive traction and twisting of the neck during shoulder delivery can stretch or tear the brachial plexus nerves, leading to Erb’s palsy. This results in weakness or paralysis of the arm. Radial palsy (B) involves injury to the radial nerve, not typically caused by shoulder delivery. Torticollis (C) is a condition characterized by neck muscle contracture, not caused by excessive traction during delivery. Ecchymosis (D) refers to bruising and is not directly related to neck traction during delivery. In summary, Erb’s palsy is the correct choice due to the specific nerve injury pattern associated with excessive neck traction during shoulder delivery.
The appropriate time to perform external cephalic version in a breech presentation is at
- A. 36 gestational weeks
- B. 38 gestational weeks
- C. 42 gestational weeks
- D. 40 gestational weeks
Correct Answer: A
Rationale: Rationale for correct answer (A): At 36 weeks, the baby has enough room to move, reducing risks of complications during external cephalic version. Earlier intervention also allows for possible repeat attempts if needed. This timing aligns with guidelines for optimal success rates.
Summary of other choices:
B: 38 weeks may be too late as the baby may have less space to turn.
C: 42 weeks is post-term and poses risks for both the baby and the mother.
D: 40 weeks is close to full term and may not allow for adequate time for successful version.
What are the risks of cesarean sections?
- A. Infection
- B. Blood loss
- C. Prolonged recovery
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D because all the choices (A, B, and C) are risks associated with cesarean sections. Infection can occur at the incision site, blood loss is a common concern during surgery, and cesarean sections typically have a longer recovery time compared to vaginal delivery. Therefore, all of these risks are potential complications of undergoing a cesarean section. The other choices (A, B, and C) are incorrect individually because they only represent a subset of the risks associated with cesarean sections, while choice D encompasses all potential risks.
