A patient presents with watery diarrhea, abdominal cramps, and nausea after consuming contaminated water from a stream during a camping trip. Laboratory tests reveal oocysts in the stool sample. Which of the following parasites is most likely responsible for this infection?

Correct Answer: C

Rationale: The correct answer is C: Cryptosporidium parvum. This parasite is the most likely cause of the infection due to its presentation with watery diarrhea, abdominal cramps, and nausea after consuming contaminated water. Laboratory tests revealing oocysts in the stool sample further support this diagnosis as Cryptosporidium parvum is known to produce oocysts in the stool. Giardia lamblia (choice A) presents with similar symptoms but does not typically produce oocysts. Entamoeba histolytica (choice B) is more associated with bloody diarrhea and liver abscesses. Cyclospora cayetanensis (choice D) is also associated with watery diarrhea but is less common in this scenario. Thus, based on the symptoms and laboratory findings, Cryptosporidium parvum is the most likely culprit.

Correct Answer: C

Rationale: The correct answer is C: Renal colic due to ureteral calculus. The sudden-onset severe colicky flank pain radiating to the groin along with tenderness over the costovertebral angle and hematuria are classic symptoms of kidney stones (ureteral calculus). The pain results from the obstruction of urine flow by the stone, leading to increased pressure and spasm in the ureter. Acute pyelonephritis (choice A) presents with fever, chills, and systemic symptoms. Renal artery embolism (choice B) typically presents with acute onset severe flank pain but is associated with risk factors like atrial fibrillation. Renal infarction (choice D) presents with sudden-onset severe flank pain but is less likely than ureteral calculus in a patient with a history of nephrolithiasis.

Correct Answer: D

Rationale: The correct answer is D: Bronchodilator therapy. Bronchodilators help to relax and open up the airways, which can improve airflow and reduce symptoms such as cough, sputum production, and dyspnea in patients with chronic bronchitis. This intervention can help manage the patient's symptoms and improve their quality of life by making it easier for them to breathe. A: Smoking cessation counseling is important for overall management of chronic bronchitis, but it does not directly address the patient's current symptoms. B: Oral antibiotic therapy may be indicated if there is evidence of a bacterial infection, but it is not the first-line treatment for managing chronic bronchitis symptoms. C: Home oxygen therapy may be necessary for patients with severe hypoxemia, but it is not typically the first intervention for managing symptoms of chronic bronchitis without evidence of significant oxygen desaturation.

Correct Answer: C

Rationale: The correct answer is C: Malpractice. Malpractice refers to professional negligence or failure to perform duties according to accepted standards of practice. In this scenario, the surgeon's act of cutting the patient's bladder during an appendectomy could be considered a breach of duty and failure to provide the expected standard of care, which falls under malpractice. Battery (A) involves intentional harmful or offensive contact without consent. Negligence (B) is the failure to exercise reasonable care, but in this case, it was more than just a lack of care. Tort (D) refers to a civil wrong that causes harm, but malpractice is a specific type of tort related to professional negligence.

Correct Answer: A

Rationale: Demonstrating breastfeeding positions that minimize pressure on the incision site should be the nursing intervention prioritized to address the client's concerns. This is important because it ensures that the client can breastfeed comfortably while also protecting the healing incision. By showing the client appropriate positions, such as the football hold or side-lying position, the nurse can help minimize discomfort and promote successful breastfeeding without compromising the cesarean incision's healing process. It is crucial to support the client in establishing a good latch and positioning to encourage proper milk transfer and bonding while being mindful of the incision site.

Correct Answer: C

Rationale: The correct answer is C: Notify the anesthesia provider for further assessment. This is the most appropriate action because an anesthesia provider is trained to assess and manage changes in blood pressure during surgery. Administering antihypertensive medication (A) without proper assessment can be dangerous. Documenting the readings (B) is important but not the immediate action. Continuing to monitor closely (D) is necessary but notifying the anesthesia provider for further assessment should be the priority.

Correct Answer: C

Rationale: The scenario described in the question is consistent with acute cholecystitis, which is inflammation of the gallbladder usually caused by an impacted gallstone in the cystic duct. The key clinical features of acute cholecystitis include fever, chills, right upper quadrant abdominal pain (which can be localized to the right upper quadrant), tenderness in the right upper abdomen, and a positive Murphy's sign (pain and inspiratory arrest upon palpation of the right upper quadrant). This condition is more common in pregnant women due to hormonal changes that can lead to gallstone formation and subsequent inflammation of the gallbladder. Ectopic pregnancy, pelvic inflammatory disease, and ovarian torsion typically present with different clinical features compared to those described in acute cholecystitis.

Correct Answer: B

Rationale: The correct answer is B because an empowered nurse feels in control and valued, leading to job satisfaction. Enthusiasm shows motivation and engagement with their work. Being ethical indicates a commitment to moral principles, contributing to a sense of fulfillment. Choice A is incorrect as competitiveness and self-centeredness do not necessarily equate to job satisfaction. Euphoria may not be a sustainable indicator of satisfaction. Choice C is incorrect because being a loner and egoistic are not traits associated with job satisfaction. Reactivity may suggest a lack of control or frustration. Choice D is incorrect as being outgoing and competitive might not directly translate to job satisfaction. Sensitivity alone does not guarantee satisfaction in the workplace.

Correct Answer: B

Rationale: The correct answer is B: 20-Gauge. The smaller the gauge number, the larger the diameter of the catheter. Blood transfusions typically require a larger catheter size to prevent hemolysis and ensure proper flow. A 20-Gauge catheter is larger than 22-Gauge, 18-Gauge, and 12-Gauge, making it suitable for administering blood. 22-Gauge is too small and can cause hemolysis, 18-Gauge is smaller than the recommended size for blood transfusions, and 12-Gauge is too large and can cause damage to the vein.
