Question 1 of 5

While participating in sports, it is not uncommon for people to be subjected to sudden rotational injuries that result in the abrupt rotation of the cerebral cortex around the more fixed midbrain structures. This can interrupt input and outflow from the reticular activating system and result in what clinical phenomenon?

Correct Answer: A

Rationale: The correct answer is A: Epidural hematoma. 1. Sudden rotational injuries can cause tearing of the middle meningeal artery, leading to an epidural hematoma. 2. The hematoma can compress the brain, disrupting the reticular activating system, causing altered consciousness. 3. Uncal herniation (B) involves herniation of the uncus, not rotation-related. 4. Concussion (C) is a mild traumatic brain injury, not directly related to rotational injuries. 5. Contrecoup injury (D) is when the brain impacts the opposite side of the skull due to sudden deceleration, not rotation-induced.

Question 2 of 5

The AGACNP is covering an internal medicine service and is paged by staff to see a patient who has just pulled out his ET tube. After the situation has been assessed, it is clear that the patient will go into respiratory failure and likely die if he is not reintubated. The patient is awake and alert and is adamant that he does not want to be reintubated. The AGACNP is concerned that there is not enough time to establish a DNRthe patient needs to be reintubated immediately and already is becoming obtunded. Which ethical principles are in conflict here?

Correct Answer: A

Rationale: The correct answer is A: Veracity and beneficence. Veracity refers to truthfulness, and the AGACNP is facing a conflict between being honest with the patient about the need for reintubation (veracity) and providing beneficence by ensuring the patient receives necessary medical care to prevent harm. The patient's autonomy and right to make decisions are not directly in conflict since the patient is conscious, and autonomy is respected by honoring the patient's wishes. Justice is also not in conflict here as it does not pertain to the immediate ethical dilemma of reintubation. Autonomy and beneficence are not in direct conflict as the patient's autonomy is being respected by allowing them to make an informed decision. Nonmalfeasance is not directly applicable in this scenario.

Question 3 of 5

Neonate born of a diabetic mother is fed within the first 15 minutes to prevent

Correct Answer: B

Rationale: The correct answer is B: Hypoglycaemia. Neonates born to diabetic mothers are at risk of hypoglycaemia due to high insulin levels in utero. Feeding the newborn within the first 15 minutes helps maintain blood glucose levels. Hypocalcaemia, hyponatraemia, and hypokalaemia are not typically immediate concerns in neonates born to diabetic mothers.

Question 4 of 5

Jennifer is an RN applicant for a staff nurse position in the surgical ICU. She has had a screening PPD and comes back in 48 hours to have it read. There is a 12-mm induration at the site of injection. A chest radiograph is negative. The AGACNP knows that the next step in Jennifers evaluation and management should include

Correct Answer: A

Rationale: The correct answer is A: No further care, because the chest radiograph is negative. In this scenario, Jennifer has a positive PPD test with a 12-mm induration but a negative chest radiograph, indicating latent TB infection. The negative chest radiograph rules out active TB disease. As a result, Jennifer does not require further evaluation or treatment for active TB. The positive PPD alone does not warrant further investigations such as Quantiferon assay (B) or prophylactic therapy (C) as these are not indicated for latent TB infection without active disease. Beginning therapy for pulmonary TB (D) is unnecessary and potentially harmful as Jennifer does not have active TB. Thus, the correct course of action is to provide no further care based on the negative chest radiograph.

Question 5 of 5

A fetal associated risk of prolonged pregnancy includes

Correct Answer: A

Rationale: The correct answer is A: Fetal macrosomia. Prolonged pregnancy increases the risk of fetal macrosomia due to continued fetal growth beyond the normal term. This can lead to complications during delivery, such as shoulder dystocia and birth injuries. Placental dysfunction and cesarean section are possible outcomes of prolonged pregnancy but are not directly associated with fetal risks in this context. Shoulder dystocia is a potential complication of fetal macrosomia but is not a direct fetal risk of prolonged pregnancy.
