Midwifery Exam Practice Questions Questions
Question 1 of 9
The comprehensive serologic assessment of a patient with Cushings syndrome is likely to produce which constellation of findings?
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.
Question 2 of 9
During induction of labor with syntocinon, drops increase is stopped prematurely on
Correct Answer: C
Rationale: Step-by-step rationale for choice C: 1. Progressive cervical dilatation indicates effective labor progress. 2. Stopping the syntocinon drops prematurely allows natural labor progression. 3. Prematurely stopping drops before reaching full dilation may hinder labor. 4. Achieving cervical dilatation is a crucial indicator for successful labor. Summary: A: Contractions should be strong, not just moderate. B: Maternal observations alone do not determine labor progress. D: Fetal-related observations are important but not the primary indicator for stopping drops.
Question 3 of 9
How can Braxton Hicks contractions be differentiated from true labor?
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.
Question 4 of 9
What is the role of the placenta in pregnancy?
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.
Question 5 of 9
Based upon an understanding of the normal relationship between gastrin levels and acid secretion, the AGACNP recognizes that which of the following combinations is almost diagnostic of gastrinoma?
Correct Answer: A
Rationale: The correct answer is A: Hypogastrinemia and acid hyposecretion. Gastrinoma is a tumor that secretes excessive gastrin, leading to hypergastrinemia and increased acid secretion. However, due to a negative feedback mechanism, chronic exposure to high gastrin levels can cause downregulation of gastrin receptors on parietal cells, leading to decreased acid secretion. Therefore, in gastrinoma, despite high gastrin levels, acid secretion may be reduced due to this negative feedback loop. Choices B, C, and D are incorrect because they do not align with the expected relationship between gastrin levels and acid secretion in gastrinoma.
Question 6 of 9
How does the maternal microbiome influence the health of the fetus during pregnancy?
Correct Answer: B
Rationale: The correct answer is B: By altering immune development. The maternal microbiome plays a crucial role in shaping the fetal immune system during pregnancy. Microbes in the mother's body can influence the development of the fetus's immune system through various mechanisms, such as immune cells crossing the placenta. This interaction helps the fetus develop tolerance to maternal antigens. Choice A (By increasing fetal weight) is incorrect because the maternal microbiome's influence is not primarily related to weight gain. Choice C (By reducing placental oxygen levels) is incorrect as it does not directly relate to the immune system development. Choice D (By enhancing amniotic fluid) is incorrect as the main influence is on the immune system rather than amniotic fluid enhancement.
Question 7 of 9
When caring for a mother following an assisted vaginal delivery, it’s MOST important to remember that
Correct Answer: D
Rationale: The correct answer is D because additional nursing interventions are necessary to ensure an uncomplicated postpartum period. After an assisted vaginal delivery, the mother may experience increased pain, perineal trauma, and a higher risk of postpartum hemorrhage. Nursing interventions such as pain management, wound care, monitoring for signs of infection, and emotional support are crucial for the mother's recovery. A is incorrect because both vacuum extractors and forceps can cause trauma to the baby and mother's perineum, and the safety of one over the other depends on various factors. B is incorrect as the development of a cephalhematoma is not a normal expected outcome of assisted vaginal delivery and should be monitored and managed appropriately if it occurs. C is incorrect as the use of instruments during childbirth, while not as common as spontaneous vaginal deliveries, is not rare and can be necessary in certain situations to ensure the safety of the mother and baby.
Question 8 of 9
A condition of trial of scar is
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.
Question 9 of 9
Complete placenta praevia is also referred to as
Correct Answer: A
Rationale: Placenta praevia is classified into four types based on the degree of coverage of the cervix by the placenta. Complete placenta praevia, where the internal os is completely covered by the placenta, is referred to as Type 4. This is the correct answer as it accurately describes the specific condition. Choices B, C, and D are incorrect as they do not correspond to the classification system for placenta praevia.
