When examining a patient with abdominal pain, the AGACNP knows that tenderness to percussion is analogous to

Correct Answer: A

Rationale: The correct answer is A: Tympany. Tenderness to percussion is analogous to tympany as both indicate the presence of gas-filled structures. When a patient experiences tenderness to percussion in the abdomen, it suggests that there is gas or air present in the abdomen, leading to a hollow, drum-like sound upon percussion, which is characteristic of tympany. Guarding (B) is the involuntary contraction of abdominal muscles to protect the underlying organs, not related to percussion. Rebound tenderness (C) is the pain experienced when pressure is released during palpation, not percussion. Somatic pain (D) refers to pain originating from the skin, muscles, or bones, not related to percussion findings.

Correct Answer: D

Rationale: The correct answer is D because the placenta performs multiple crucial roles in pregnancy. Firstly, it produces hormones essential for maintaining the pregnancy. Secondly, it provides nutrients and oxygen to the fetus for growth and development. Lastly, it removes waste products from the fetus to ensure a healthy environment. Choices A, B, and C individually do not cover all the functions of the placenta, making them incorrect. Selecting option D acknowledges the comprehensive functions of the placenta during pregnancy.

Correct Answer: A

Rationale: Rationale: A needle biopsy is appropriate for definitive diagnosis of hepatic hemangiomas, ruling out other liver lesions. It helps determine if they are benign or malignant. This will guide further management decisions. Summary: B: Annual ultrasound is unnecessary for benign hemangiomas. C: Surgery is not indicated for asymptomatic hepatic hemangiomas. D: Documenting the finding is important but not the appropriate next step in management.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): A trial of scar is indicated when a woman has had no more than two previous caesarean sections. This is because the risk of uterine rupture increases with each subsequent caesarean section due to scar tissue weakening. Limiting the number of previous scars reduces this risk. Therefore, option C is correct. Summary of Incorrect Choices: A: Estimated fetal weight is not a determining factor for a trial of scar. B: Availability of a level one hospital nearby is important for emergency situations but not a criteria for trial of scar. D: Adequate pelvis with true conjugate 10.5cm is important for vaginal delivery but not a specific requirement for a trial of scar.

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.
