Correct Answer: C

Rationale: The correct answer is C - the circulating and scrub nurse first assistant. The circulating nurse is responsible for counting needles, sponges, and instruments during the closing of the surgical incision to ensure nothing is left inside the patient. The scrub nurse first assistant also plays a crucial role in this process by assisting in the counting and keeping track of the items used during the procedure. The other choices are incorrect because the surgeon and anesthesiologist (A) are not typically involved in counting items during the surgical closure, the surgeon and the registered (B) may not have the necessary training for accurate counting, and the anesthesiologist and anesthetist (D) are not directly involved in the surgical closing process.

Correct Answer: C

Rationale: The most pertinent nursing diagnosis for the patient with a right femur fracture stabilized in a full leg cast is "Acute pain" (Choice C). The rationale for this is as follows: 1. The patient is experiencing moderate discomfort due to the fracture and immobilization in the cast, indicating a need for pain management. 2. Acute pain is a priority in this situation as it can impact the patient's comfort, mobility, and overall recovery. 3. Managing pain effectively is crucial for promoting healing, preventing complications, and improving the patient's quality of life. 4. Posttrauma syndrome (Choice A) may be a consideration in the long term but is not the immediate priority. Constipation (Choice B) is not the most pertinent nursing diagnosis in this scenario. Anxiety (Choice D) may be present but addressing pain is more urgent and directly related to the patient's current condition.

Correct Answer: D

Rationale: The correct answer is D: Human papilloma virus (HPV) infection at age 32. HPV is a known risk factor for cervical cancer as it can lead to cellular changes in the cervix. Here's the rationale: 1. HPV is a sexually transmitted infection that can cause abnormal cell growth in the cervix. 2. Persistent HPV infection is a major risk factor for developing cervical cancer. 3. Age 32 is within the typical age range for HPV infection and the development of cervical cancer. 4. Choices A, B, and C are unrelated to the primary risk factor for cervical cancer, which is HPV infection.

Correct Answer: B

Rationale: The correct answer is B: Protein. Antibodies are a type of protein produced by the immune system to help identify and neutralize pathogens like bacteria and viruses. Proteins are composed of amino acids, which are the building blocks of proteins. Antibodies have a specific structure that allows them to bind to specific antigens. Fat (A), Sugar (C), and Carbohydrates (D) are not primary components of antibodies and do not play a significant role in their structure or function.

Correct Answer: D

Rationale: The correct answer is D: leukocytosis. Carbamazepine can cause bone marrow suppression, leading to leukocytosis. Monitoring for elevated white blood cell count is essential to detect this potential complication early. A: Adult respiratory distress syndrome is not a common complication of carbamazepine. B: Elevated levels of phenytoin is not a direct complication of carbamazepine use. C: Diplopia is a common side effect of carbamazepine, not a potential complication like leukocytosis.
