Question 1 of 9

The recommended number of chest compressions for neonatal resuscitation is

Correct Answer: A

Rationale: The correct answer is A: 60 compressions coordinated with 30 breaths per minute. In neonatal resuscitation, the recommended compression-to-ventilation ratio is 3:1. This means 3 compressions are given followed by 1 breath. With a target compression rate of 120 per minute, this translates to 60 compressions coordinated with 30 breaths per minute. Each compression should be at a depth of about one-third the anterior-posterior diameter of the chest. This ratio and rate are crucial for maintaining adequate circulation and oxygenation during neonatal resuscitation. Choice B: 3 compressions coordinated with 1 breath per minute is too slow and would not provide enough support for the neonate's circulation. Choice C: 1 compression coordinated with 3 breaths per minute would not provide sufficient compressions to maintain circulation. Choice D: 90 compressions coordinated with 30 breaths per minute would result in an incorrect compression-to-vent

Question 2 of 9

Mr. Costigan is a 50-year-old male patient who recently had a screening colonoscopy because it was recommended by his primary care provider as a screening measure. He received a report that noted inflammatory polyps. He is concerned because one of his friends had polyps that turned into cancer. While advising Mr. Costigan, the AGACNP tells him that

Correct Answer: B

Rationale: Step 1: Family history of colon cancer is a significant risk factor for developing colon cancer. Step 2: By discussing with his parents, Mr. Costigan can determine if there is a family history of colon cancer. Step 3: Knowing this information can help assess his own risk and guide appropriate screening and preventive measures. Step 4: The primary danger for Mr. Costigan lies in potential genetic predisposition rather than the presence of inflammatory polyps. Step 5: Therefore, discussing with family members about any history of colon cancer is crucial for his overall risk assessment and management. Summary: - Choice A is incorrect as the frequency of colonoscopy should be individualized based on the patient's risk factors. - Choice C is incorrect as all polyps have the potential to become cancerous, especially inflammatory polyps. - Choice D is incorrect as consulting an oncologist at this stage is premature without first assessing family history.

Question 3 of 9

Flexion-distraction injuries of the thoracolumbar spine are most commonly caused by

Correct Answer: B

Rationale: The correct answer is B: Rotational injury. Flexion-distraction injuries of the thoracolumbar spine are often caused by rotational forces that occur during accidents such as motor vehicle collisions or falls. These forces lead to the spine being twisted, causing separation of the vertebrae. Blunt trauma (A) can cause various spinal injuries but is not specific to flexion-distraction injuries. Seat belts (C) are designed to prevent spinal injuries by restraining the body during a collision. Gunshot wounds (D) can cause spinal cord injuries but are not commonly associated with flexion-distraction injuries of the thoracolumbar spine.

Question 4 of 9

R. R. is a 71-year-old female who presents with left lower quadrant pain that started out as cramping but has become more constant over the last day. She reports constipation over the last few days but admits that for as long as she can remember she has had variable bowel habits. Her vital signs are normal, but physical examination reveals some tenderness in the left lower quadrant. Which diagnostic test is most likely to support the leading differential diagnosis?

Correct Answer: D

Rationale: The correct diagnostic test for the patient is a barium enema. This test is commonly used to evaluate the colon and rectum for conditions such as colonic obstruction, inflammatory bowel disease, or colorectal cancer. In this case, the patient's presentation of left lower quadrant pain with a history of constipation and variable bowel habits suggests a possible colonic obstruction, which can be visualized through a barium enema. A CT scan with contrast may be helpful in some cases but may not provide as clear a view of the colon as a barium enema. CBC with WBC differential is a general blood test and would not directly aid in diagnosing colonic issues. Colonoscopy, while a valuable tool for evaluating the colon, may not be suitable for this patient initially due to the acute nature of the presentation and the need to first rule out a potential obstruction.

Question 5 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 6 of 9

The MAIN aim of encouraging plenty of fluids to a postnatal client with urinary tract trauma is to

Correct Answer: A

Rationale: The correct answer is A: Keep client well hydrated. Encouraging plenty of fluids helps prevent dehydration, maintain adequate urine output, and promote flushing of the urinary tract to prevent infections, all crucial for postnatal clients with urinary tract trauma. Proper hydration also supports overall health and aids in the healing process. B: Maintain proper fluid balance - While important, the main aim is to keep the client well hydrated to support healing. C: Facilitate proper healing - Proper hydration does facilitate healing, but the primary aim is to keep the client well hydrated. D: Control growth of organisms - While hydration can help in preventing infections, the main aim is to keep the client well hydrated.

Question 7 of 9

The main diagnostic feature of puerperal pyrexia is

Correct Answer: A

Rationale: The correct answer is A: Fever ≥ 38°C for three consecutive occasions. Puerperal pyrexia is defined as fever occurring after childbirth. The key diagnostic feature is the presence of fever (≥ 38°C) on three consecutive occasions, indicating a persistent infection. Choice B is incorrect because it doesn't specify the need for consecutive occasions. Choice C is incorrect as it extends the duration of fever to three weeks, which is too long for typical puerperal pyrexia. Choice D is incorrect as it mentions "occasionally" instead of "consecutively," which is not indicative of a consistent fever pattern seen in puerperal pyrexia.

Question 8 of 9

Causes of puerperal pyrexia are entirely obstetrically related.

Correct Answer: B

Rationale: Step 1: Puerperal pyrexia refers to fever occurring after childbirth. Step 2: Causes can be obstetric (infection) or non-obstetric (e.g., urinary tract infection). Step 3: Non-obstetric causes are also common postpartum. Step 4: Therefore, puerperal pyrexia is not entirely obstetrically related. Step 5: Hence, the correct answer is B (FALSE).

Question 9 of 9

The baby dies immediately after birth due to the presence of

Correct Answer: C

Rationale: The correct answer is C: Truncus arteriosus. In this congenital heart defect, a single large blood vessel arises from the heart instead of the normal two separate vessels (aorta and pulmonary artery). This results in mixing of oxygenated and deoxygenated blood, leading to severe cyanosis and inadequate oxygen supply to the body. This condition is incompatible with life, causing immediate death after birth. A: Pulmonary stenosis and B: Aortic coarctation are also congenital heart defects but do not typically result in immediate death after birth. Pulmonary stenosis obstructs blood flow to the lungs, while aortic coarctation causes narrowing of the aorta. D: Ductus arteriosus is a normal fetal blood vessel that connects the pulmonary artery and the aorta but usually closes shortly after birth. Failure of closure can lead to health issues, but it is not typically a cause of immediate death after birth.
