A patient presents with fever, chills, and costovertebral angle tenderness. Urinalysis reveals pyuria and bacteriuria. Which of the following conditions is most likely?

Correct Answer: A

Rationale: Acute pyelonephritis is the most likely condition based on the patient presentation and urinalysis findings described. Acute pyelonephritis is an infection of the renal parenchyma and pelvis, typically caused by ascending bacteria from the lower urinary tract. The classic symptoms include fever, chills, flank pain, and costovertebral angle tenderness (tenderness over the kidneys). The presence of pyuria (pus in the urine) and bacteriuria (bacteria in the urine) on urinalysis further supports the diagnosis of acute pyelonephritis. It is crucial to diagnose and treat acute pyelonephritis promptly to prevent complications and recurrent infections.

Correct Answer: D

Rationale: Escherichia coli (E. coli) is the MOST common causative agent of urinary tract infection (UTI), accounting for approximately 80-85% of all cases. E. coli is a type of bacteria that naturally resides in the gastrointestinal tract and can easily migrate to the urinary tract, causing infection. Its prevalence in UTIs is due to various factors such as its ability to adhere to the uroepithelial cells and form biofilms, leading to persistent infections. Therefore, E. coli is the most common organism responsible for UTIs in both community and healthcare settings.

Correct Answer: A

Rationale: The nurse sharing Mr. Steve's medical records with a group of visiting members of a medical mission team violates his right to expect that all communications and records pertaining to his care should be treated as confidential. Patient confidentiality is a fundamental ethical principle in healthcare that protects a patient's privacy and sensitive information. Sharing medical records without the patient's consent breaches this confidentiality and can lead to legal and ethical consequences. It is important for healthcare providers to maintain the confidentiality of patient information to uphold trust between patients and healthcare professionals.

Correct Answer: A

Rationale: Nulliparity, which refers to never having given birth to a child, is the most common risk factor for the development of ovarian cancer. Women who have never been pregnant have a higher risk of developing ovarian cancer compared to those who have had children. This association is believed to be related to the uninterrupted ovulation cycles that nulliparous women experience, leading to changes in the surface epithelium of the ovary that predispose them to cancer development. Conversely, factors like early menarche, late menopause, and a family history of breast cancer are also associated with an increased risk of ovarian cancer but are not as commonly observed as nulliparity in the general population.

Correct Answer: B

Rationale: The symptoms described such as memory loss, impaired judgment, personality changes, difficulty with language, motor function, and coordination all point towards Alzheimer's disease. Alzheimer's is a progressive neurodegenerative disease that primarily affects memory and cognitive functions. Over time, it leads to severe impairment in daily activities and overall functioning. While Parkinson's disease, Huntington's disease, and ALS can also present with neurological symptoms, the combination of gradual-onset memory loss, cognitive decline, and functional impairments seen in this scenario is most characteristic of Alzheimer's disease.

Correct Answer: A

Rationale: If visible residue is noticed on the surgical instruments, it is crucial to re-sterilize them before using them for any procedure. Visible residue may indicate that the instruments are not sterile and could potentially introduce contaminants into the patient during the procedure, leading to infection or other complications. It is essential to maintain the highest standards of cleanliness and sterility in healthcare settings to ensure patient safety. Therefore, the nurse should take immediate action to re-sterilize the instruments before proceeding with any surgical procedure.

Correct Answer: A

Rationale: Participating in professional organizations can be a valuable way for Nurse Bea to enhance her career in nursing aside from enrolling in graduate school. Professional organizations provide networking opportunities, access to resources and information, opportunities for professional development through workshops and conferences, and a platform for engaging in advocacy efforts to promote the nursing profession. By being an active member of a professional organization, Nurse Bea can further her knowledge, skills, and connections within the nursing field, which can contribute to her career advancement.

Correct Answer: A

Rationale: When planning for a client's care, a primary consideration is to prevent problems related to immobility. Immobility can lead to a range of complications such as pressure ulcers, muscle weakness, joint contractures, and decreased circulation. To maintain the client's overall health and well-being, it is essential to address mobility issues and implement strategies to prevent complications associated with immobility. By prioritizing interventions that promote movement and prevent immobility-related problems, the client's quality of life can be improved and potential health risks mitigated.

Correct Answer: D

Rationale: Thyroid nodules are abnormal growths of thyroid cells that form a lump within the thyroid gland. When a thyroid nodule becomes large enough, it can cause compressive symptoms such as difficulty swallowing and breathing. The presence of colloid nodules on fine-needle aspiration biopsy indicates a benign and common type of thyroid nodule. In this case, the symptoms are likely due to the physical pressure exerted by the thyroid nodule, rather than an underlying endocrine disorder like Hashimoto's thyroiditis, Graves' disease, or diabetes mellitus. Therefore, the most likely cause of the patient's symptoms is the thyroid nodule itself.
