Correct Answer: C

Rationale: Nitroglycerin sublingual tablets are meant to be dissolved under the tongue to allow for rapid absorption into the bloodstream. Placing the tablet under the tongue helps to bypass the first-pass metabolism in the liver, leading to a quicker onset of action and chest pain relief. Chewing, swallowing, or applying the tablet to the skin will result in decreased effectiveness or delayed onset of action. Therefore, it is important for the patient to be instructed to place the nitroglycerin tablet under the tongue and allow it to dissolve for optimal therapeutic benefit.

Correct Answer: A

Rationale: Betamethasone (Celestone) is a corticosteroid medication that is commonly used to promote fetal lung maturity in pregnant women at risk of preterm delivery. Administering betamethasone to the mother helps accelerate the production of surfactant in the fetal lungs, which is essential for proper lung function and development. This medication is typically given to pregnant women between 24 and 34 weeks of gestation to reduce the risk of respiratory distress syndrome in preterm infants. It does not prevent premature closure of the ductus arteriosus, delay delivery, or stop premature uterine contractions.

Correct Answer: D

Rationale: When someone is bitten by a dog, the most important first aid step is to wash the wound thoroughly with running water. This helps to remove any dirt or bacteria from the wound, reducing the risk of infection. Washing the wound with garlic (choice A) is not recommended as it can irritate the skin and may not effectively clean the wound. Feeding the dog (choice B) is not relevant to treating the bite wound. Bleeding the bitten area (choice C) is also not necessary and can actually increase the risk of infection. Therefore, the best advice the nurse should give in case of a dog bite is to wash the wound thoroughly with running water.

Correct Answer: D

Rationale: After childbirth, the uterus undergoes involution, which is the process of returning to its pre-pregnant size and location. Initially, the fundus is firm and located at or just below the level of the umbilicus immediately after delivery. Over the next 24 hours, the fundus should gradually decrease in height as involution progresses. By the day after delivery, the nurse would expect the fundal assessment to be in line with the umbilicus or slightly below it, indicating normal involution of the uterus. If the fundus remains high or deviates from this expected progression, further assessment and intervention may be needed to prevent complications such as postpartum hemorrhage.

Correct Answer: B

Rationale: Administering ice packs to the perineum is the priority nursing intervention to provide relief for perineal pain and discomfort in a postpartum client. Ice packs help to reduce swelling and inflammation in the perineal area, which can help alleviate pain. It is a safe and effective method to provide immediate relief and promote comfort for the client. Other interventions such as encouraging ambulation, administering analgesics, and recommending warm sitz baths can also be beneficial, but in the initial management of perineal pain, ice packs are the most appropriate choice.
