Question 1 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 2 of 9

The main feature in the initial stage of shock is

Correct Answer: B

Rationale: The correct answer is B: Tachycardia. In the initial stage of shock, the body tries to compensate for decreased perfusion by increasing heart rate to maintain blood flow to vital organs. Cyanosis (A) is a late sign of shock due to inadequate oxygenation. Sweat beads (C) are a non-specific response and not a defining feature of shock. Hypotension (D) typically occurs in the later stages of shock as the body's compensatory mechanisms start to fail. Tachycardia is the earliest and most consistent sign of shock, reflecting the body's attempt to maintain cardiac output.

Question 3 of 9

Deep transverse arrest is

Correct Answer: D

Rationale: The correct answer is D because deep transverse arrest occurs when the level of the occiput and the sinciput is the same, leading to a failure of descent of the fetal head through the pelvis. This alignment issue hinders the progress of labor despite adequate contractions. A: Incorrect. Flexion being well maintained is not a defining characteristic of deep transverse arrest. B: Incorrect. While strong uterine contractions can contribute to labor challenges, deep transverse arrest is specifically related to the alignment of the fetal head. C: Incorrect. The curvature of the sacrum is not directly related to deep transverse arrest.

Question 4 of 9

Which of the following is NOT a source of pain in labour?

Correct Answer: B

Rationale: Step 1: Uterine contractions are a physiological process in labor causing pain due to muscle contractions. Step 2: Cervical dilatation involves the opening of the cervix, which can cause pain and discomfort. Step 3: Pelvic floor stretching occurs as the baby moves through the birth canal, leading to pain. Step 4: Socio-cultural norms do not directly cause physical pain in labor, making choice B the correct answer. Other choices directly relate to physical processes causing pain.

Question 5 of 9

Obstructed labor MAINLY results due to

Correct Answer: B

Rationale: The correct answer is B: Cephalopelvic disproportion. This condition occurs when the baby's head is too large to pass through the mother's pelvis during labor. This leads to obstructed labor, causing complications for both the mother and the baby. Maternal exhaustion (A) may occur as a result of prolonged labor but is not the primary cause of obstructed labor. Microsomic fetus (C) refers to a small baby and would not typically cause obstructed labor. Fetal exsanguination (D) is the loss of blood from the fetus and is not a common cause of obstructed labor. Cephalopelvic disproportion is the most common reason for obstructed labor as it directly affects the passage of the baby through the birth canal.

Question 6 of 9

TB in pregnancy predisposes a mother to premature labour due to

Correct Answer: D

Rationale: The correct answer is D. TB in pregnancy can lead to premature labor due to the fever experienced. Fever increases the risk of premature labor by triggering uterine contractions. Poor maternal appetite (A) and severe anemia (B) may impact the mother's health but are not directly linked to premature labor. Adverse reactions of anti-TB drugs (C) could potentially affect the mother's health but are not a direct cause of premature labor.

Question 7 of 9

Placental parasitation is associated with

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.

Question 8 of 9

Congenital retraction of the prepuce, so that the glans is permanently exposed, is known as

Correct Answer: B

Rationale: Congenital retraction of the prepuce, leading to permanent glans exposure, describes paraphimosis. This condition occurs when the foreskin is pulled back and cannot return to its normal position, causing pain and swelling. Phimosis (A) is the inability to retract the foreskin over the glans. Hypospadias (C) is a urethral opening on the underside of the penis. Hermaphroditism (D) is a rare condition of having both male and female reproductive organs. Paraphimosis (B) is the specific term for the given scenario.

Question 9 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.
