Correct Answer: A

Rationale: Shoulder dystocia is an obstetric emergency where one of the baby's shoulders becomes impacted behind the mother's pubic bone after the head delivers. This can lead to compression of the umbilical cord and compromise fetal oxygenation. The most critical nursing intervention in managing shoulder dystocia is applying suprapubic pressure to dislodge the impacted shoulder and allow for delivery of the baby. By gently pushing downwards on the mother's abdomen just above the pubic bone, the shoulder can be released, and the baby can be delivered successfully. This intervention should be prioritized to prevent potential complications for both the mother and the baby. Episiotomy may be considered if necessary, but it is secondary to addressing the shoulder dystocia. Oropharyngeal airway insertion and administering magnesium sulfate are not indicated in the immediate management of shoulder dystocia.

Correct Answer: A

Rationale: In cases of poisoning, the main goals are to inactivate the poison to prevent further harm, administer the specific antidote if available to counteract the effects of the poison, and support vital organ functions to help the patient recover. Inducing the patient to vomit (III) is not always recommended as it can potentially cause more harm, especially if the ingested substance is corrosive. Therefore, the most appropriate goals in poisoning are to inactivate the poison, administer the specific antidote, and support vital organ functions.

Correct Answer: A

Rationale: The presentation described with sudden-onset, painless vision loss, a cherry-red spot at the macula, and attenuated retinal vessels is classic for central retinal artery occlusion (CRAO). CRAO occurs when the central retinal artery, which supplies blood to the inner retinal layers, becomes occluded. The cherry-red spot is due to the exposure of the underlying choroid, which still appears red as it is not affected by the blockage. Attenuated retinal vessels and a pale retina may also be seen due to ischemia. In contrast, central retinal vein occlusion (choice B) presents with sudden painless vision loss, retinal hemorrhages, dilated retinal veins, and cotton-wool spots. Retinal detachment (choice C) typically presents with flashes, floaters, and a curtain-like shadow across the vision. Acute angle-closure glaucoma (

Correct Answer: B

Rationale: In this scenario, the nurse is asking the patient to elaborate on their feelings and thoughts related to the upcoming surgery. By asking, "What do you fear MOST about your surgery tomorrow?" the nurse is seeking clarification to better understand the patient's concerns and enable effective communication. Seeking clarification involves asking open-ended questions that encourage the patient to express themselves more fully, allowing the healthcare provider to address their specific worries or needs more effectively.

Correct Answer: A

Rationale: For a preschooler, it is recommended that they get more than 8 hours of sleep each day. Adequate sleep is crucial for their physical development, overall health, and cognitive function. Preschoolers typically need around 10-13 hours of sleep per day to support their growth and development. Getting less than the recommended amount of sleep can lead to issues such as behavioral problems, difficulty concentrating, and poor physical development. Therefore, ensuring that a preschooler gets enough sleep is vital for their physical well-being.
