Mr. Jefferson is a 59-year-old male who presents to the emergency department complaining of severe abdominal pain. His medical history is significant for dyslipidemia, and he takes 40 mgof simvastatin daily. He admits to drinking 6 to 10 bottles of beer nightly and to smoking 1 packs of cigarettes a day. He denies any history of chest pain or cardiovascular disease. He was in his usual state of good health until a couple of hours ago, when he developed this acute onset of severe pain in the upper abdomen. He says that he tried to wait it out at home but it was so bad he finally came in. His vital signs are as follows temperature 99.1F, pulse 129 bpm, respirations 22 breaths per minute, and blood pressure 13784 mm Hg. The abdomen is diffusely tender to palpation with some guarding but no rebound tenderness. The AGACNP anticipates that which of the following laboratory tests will be abnormal?

Correct Answer: A

Rationale: The correct answer is A: A complete blood count and RBC differential. In this case, Mr. Jefferson presents with severe abdominal pain, which could indicate various conditions like pancreatitis, a possible complication of his heavy drinking. A complete blood count (CBC) with RBC differential can help assess for signs of inflammation or infection, which may be elevated in conditions like pancreatitis. The RBC differential can also provide insights into potential causes of abdominal pain, such as anemia or other blood disorders. Summary: - B: Liver function enzymes may be affected in conditions like alcoholic liver disease, but in this case, the focus should be on investigating acute abdominal pain. - C: Serum amylase, lipase, and glucose are typically checked in cases of suspected pancreatitis, but a CBC with RBC differential would provide a more comprehensive initial assessment. - D: A basic metabolic panel may not directly address the underlying cause of the acute abdominal pain and is not the most appropriate test to anticipate

Correct Answer: D

Rationale: The correct answer is D: Escherichia coli. E. coli is the most common causative organism of pyelonephritis due to its prevalence in the gastrointestinal tract. It has specific virulence factors that enable it to ascend the urinary tract and cause infection. Streptococcus faecalis, Proteus vulgaris, and Staphylococcus pyogene are less commonly associated with pyelonephritis compared to E. coli.

Correct Answer: B

Rationale: The correct answer is B: Face presentation. Vaginal delivery is possible in face presentation as the baby's head is extended, allowing for descent through the birth canal. Brow presentation (A) and shoulder presentation (C) may require cesarean delivery due to the atypical presentation of the baby. Unstable lie (D) refers to the baby being in a transverse position, which also necessitates a cesarean section. Face presentation is the only option where vaginal delivery may be possible due to the extended position of the baby's head.

Correct Answer: C

Rationale: The correct answer is C: Homeopathy. Homeopathy involves using highly diluted substances to stimulate the body's natural healing processes. In labor, homeopathy can help manage pain and support relaxation. Entonox (A) and Diamorphine (D) are pharmacological measures, while Cyclothane (B) is not a recognized pain relief option in labor. Homeopathy aligns with non-pharmacological approaches, making it the most suitable choice for pain relief in labor.

Correct Answer: C

Rationale: The correct answer is C: Multiple gestation. Preterm birth is more common in multiple gestation pregnancies due to the increased strain on the mother's uterus and cervix. This can lead to early labor and delivery. Social habits (choice A) and genetic factors (choice B) may play a role in preterm birth but are not highly associated. Chronic conditions (choice D) can also contribute to preterm birth, but multiple gestation is a stronger predictor.

Correct Answer: D

Rationale: The correct answer is D because placenta praevia can lead to life-threatening bleeding during labor due to the placenta partially or completely covering the cervix. This condition poses a high risk of morbidity and mortality to both the mother and the baby. A: Incorrect. Bleeding in placenta praevia is not related to the segment preparing for labor. B: Incorrect. While bleeding is due to placental issues, it is specifically due to the placenta's abnormal positioning, not a pathological process. C: Incorrect. Bleeding can occur before 37 weeks in cases of placenta praevia, and the timing of bleeding is not linked to gestational age.

Correct Answer: C

Rationale: Correct Answer: C - Fine needle aspiration does not allow grading of tumors. Rationale: 1. Fine needle aspiration (FNA) collects cells for cytology evaluation, not tissue for grading. 2. Grading requires evaluation of tissue architecture, which is not possible with FNA. 3. FNA is useful for diagnosis but not for determining tumor grade. Summary: A: Incorrect - Excisional biopsy is preferred over incisional biopsy to obtain the entire tumor for diagnosis and grading. B: Incorrect - Core needle biopsy has a lower false positive rate compared to fine needle aspiration. D: Incorrect - Core needle and incisional biopsies differ in the amount of tissue sampled and potential for false results.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Cognitive ability is important for decision-making during surgery. 2. Functional status helps assess the patient's ability to recover post-surgery. 3. Competency assessment ensures the patient can consent to surgery. 4. Frailty score predicts surgical outcomes in geriatric patients. 5. Cognitive ability is not typically assessed preoperatively in the ACS/NSQIP guidelines. Summary: - A: Cognitive ability is not typically part of preoperative evaluation. - B: Functional status is important for post-surgery recovery. - C: Competency assessment is crucial for informed consent. - D: Frailty score helps predict surgical outcomes in geriatric patients.

Correct Answer: D

Rationale: The correct answer is D: Short acting insulin. In gestational diabetes, short acting insulin is preferred as it provides immediate control over blood sugar levels after meals. This is crucial in managing the condition to prevent complications for both the mother and the baby. Therapeutic diet alone (choice A) may not be sufficient to control blood sugar levels, while long-acting insulin (choice B) may not provide the rapid response needed after meals. Oral hypoglycemics (choice C) are generally avoided in pregnancy due to potential risks to the fetus. Therefore, short acting insulin is the most appropriate therapy for managing gestational diabetes effectively.
