Correct Answer: B

Rationale: Attrition is the dental condition characterized by the abnormal wearing away of tooth structure due to factors such as bruxism (grinding or clenching of teeth) or acidic erosion. Bruxism can cause tooth-to-tooth contact that leads to the wearing down of the tooth enamel and eventually can affect deeper layers of the tooth. Acidic erosion, on the other hand, is caused by the direct contact of teeth with acidic substances, which can lead to the gradual loss of tooth structure over time. Dental caries refers to tooth decay caused by bacteria, abrasion involves wearing away of tooth structure due to external factors like improper brushing habits, and erosion specifically relates to the loss of tooth structure caused by acidic substances.

Correct Answer: D

Rationale: In this scenario, the mother, who is 35 years old and illiterate but with on and off seizure, is the best candidate to sign the informed consent for a surgical procedure for the child. The mother is the primary caregiver and decision-maker for the child in most cases, and her relationship to the child is most crucial in this situation. Despite her illiteracy, she can still comprehend the importance of the procedure for her child's well-being. Additionally, accommodations can be made for an illiterate person to sign the consent form by using an "X" as a signature. It is important that the person signing the consent form has a clear understanding of the risks and benefits involved, as well as the ability to make decisions in the best interest of the child.

Correct Answer: B

Rationale: Uterine atony is caused by the markedly distended uterus and intermittent uterine contractions within 2 to 3 days after birth. It is characterized by the inability of the uterus to contract after delivery, leading to excessive bleeding postpartum. This condition is a significant risk factor for postpartum hemorrhage. Treatment may involve massage of the uterus, administration of uterotonics, and in severe cases, surgical interventions such as a hysterectomy. Retained placenta refers to incomplete expulsion of the placenta after delivery. Afterpains are the discomfort felt by some women as their uterus contracts and returns to its normal size after childbirth. A boggy uterus is another term for a uterus that feels soft, lax, or lack firm tone, which can be a sign of uterine atony.

Correct Answer: D

Rationale: Taking off the room lights and drawing the window shades would provide a calm and soothing environment for the five-year-old patient admitted due to pneumonia with symptoms of cough, respiratory distress, anxiety, and dehydration. By creating a dim and quiet atmosphere, it can help reduce the child's anxiety levels, promote rest and relaxation, and potentially aid in the management of distress caused by pneumonia. Providing a quiet and dark environment can also support the child's comfort and recovery process during the hospital stay.

Correct Answer: C

Rationale: Excessive bleeding during a surgical procedure is a critical situation that requires immediate attention. The surgeon should be notified promptly so that appropriate interventions can be initiated to control the bleeding, such as applying pressure, administering hemostatic agents, or performing additional surgical measures. The surgeon is ultimately responsible for addressing the source of bleeding and ensuring the patient's safety during the procedure. It is important for the nurse to communicate effectively and collaborate with the surgical team to manage the situation efficiently and effectively.
