What is the role of the placenta in pregnancy?
- A. Produces hormones
- B. Provides nutrients and oxygen to the fetus
- C. Removes waste products from the fetus
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D because the placenta performs multiple crucial roles in pregnancy. Firstly, it produces hormones essential for maintaining the pregnancy. Secondly, it provides nutrients and oxygen to the fetus for growth and development. Lastly, it removes waste products from the fetus to ensure a healthy environment. Choices A, B, and C individually do not cover all the functions of the placenta, making them incorrect. Selecting option D acknowledges the comprehensive functions of the placenta during pregnancy.

Placental parasitation is associated with
- A. Candidiasis prenatally
- B. Tuberculosis prenatally
- C. Multiple gestation
- D. Malaria prenatally
Correct Answer: D
Rationale: Placental parasitation is associated with Malaria prenatally because the Plasmodium parasite can infect the placenta through the bloodstream, leading to severe complications for both the mother and the fetus. This infection can result in low birth weight, preterm birth, and even stillbirth. Candidiasis, Tuberculosis, and Multiple gestation are not directly associated with placental parasitation. Candidiasis is a fungal infection, Tuberculosis is a bacterial infection, and Multiple gestation refers to carrying more than one fetus during pregnancy. Therefore, the correct answer is D, Malaria prenatally, due to the direct impact of Plasmodium parasite on the placenta and its implications on pregnancy outcomes.
The fetal head retracting against the perineum is a
- A. Gaskin sign
- B. Turtle sign
- C. Klumpke sign
- D. Chignon sign
Correct Answer: B
Rationale: The correct answer is B: Turtle sign. This sign refers to the fetal head retracting against the perineum during delivery. It indicates shoulder dystocia, a complication where the baby's shoulders get stuck after the head is delivered. This can lead to serious complications for both the baby and the mother if not managed promptly.
A: Gaskin sign is incorrect as it refers to a position where the mother is on her hands and knees during labor.
C: Klumpke sign is incorrect as it is a neurological condition affecting the lower arm and hand.
D: Chignon sign is incorrect as it is not a recognized medical term related to childbirth.
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: C
Rationale: Rationale for Correct Answer (C):
1. The patient's symptoms of decreased capacity for intake and nausea after eating suggest gastroparesis, a common complication post-ulcer surgery.
2. Given the history of complicated peptic ulcer disease and prior surgery, medication may be ineffective, necessitating potential reoperation.
3. The AGACNP advises that another surgery may be needed, indicating that medication alone may not suffice to address the issue.
Summary of Incorrect Choices:
A: Endoscopy is not necessary at this point as the symptoms are likely indicative of a functional issue rather than a structural problem.
B: While gastroparesis can occur post-ulcer surgery, the patient's symptoms are more suggestive of gastroparesis rather than chronic gastroparesis as a known complication.
D: The frequency of occurrence of symptoms after ulcer surgery is not relevant to the current management of the patient's symptoms.
The factor indicative of an abnormal labour pattern on vaginal examination is
- A. The vagina is warm and moist
- B. Cervical canal is long and thick
- C. Cervical canal is short and thin
- D. The vagina is hot and dry
Correct Answer: C
Rationale: Step 1: In normal labor, the cervix undergoes effacement and dilation.
Step 2: A short and thin cervical canal indicates progression towards labor.
Step 3: Long and thick cervical canal suggests a delay in labor progress.
Step 4: Choice C, short and thin cervical canal, is indicative of abnormal labor.
Summary: A, B, and D do not reflect changes in the cervix seen in labor, making them incorrect choices.
The comprehensive serologic assessment of a patient with Cushings syndrome is likely to produce which constellation of findings?
- A. Low potassium, high glucose, high white blood cell count
- B. High sodium, polycythemia, low BUN
- C. Low sodium, low potassium, high BUN
- D. High sodium, high chloride, high RBCs
Correct Answer: C
Rationale: The correct answer is C. In Cushing's syndrome, there is excess cortisol production leading to sodium retention, potassium loss, and increased protein breakdown. Low sodium and potassium levels along with high BUN are commonly seen in patients with Cushing's syndrome.
A: Low potassium and high glucose are possible findings, but high white blood cell count is not typically associated with Cushing's syndrome.
B: High sodium and polycythemia are not typical findings in Cushing's syndrome, and low BUN is not consistent with the protein breakdown seen in this condition.
D: High sodium and high chloride levels can be seen, but high RBCs are not typically associated with Cushing's syndrome.
