Correct Answer: A

Rationale: The nurse should prioritize screening the patient for contraindications to MRI, such as metal implants or claustrophobia, to ensure procedural safety. Metallic objects can be hazardous in an MRI environment as they can be attracted to the magnet, potentially causing harm to the patient or staff. Claustrophobia can also be a significant issue for patients undergoing an MRI scan, and identifying this beforehand allows for appropriate measures to be taken to address the patient's anxiety or discomfort. Prioritizing this screening step helps ensure the safety and well-being of the patient during the MRI procedure.

Correct Answer: D

Rationale: The appropriate nursing diagnosis for this situation is "Ineffective coping" because the patients with hypertension who stop taking their medications despite feeling good may be using this behavior as a maladaptive coping mechanism. It suggests that they might not fully understand the importance of medication adherence or are struggling to accept their diagnosis. By not adhering to their prescribed treatment, they are putting themselves at risk for complications associated with uncontrolled hypertension. Therefore, the nursing diagnosis of "Ineffective coping" addresses the patients' inability to deal with their condition in a healthy manner, leading to noncompliance with their treatment regimen.

Correct Answer: B

Rationale: Marlene opening up to the nurse about their financial difficulty indicates that she feels comfortable enough to share personal information with the nurse. This signals the establishment of a trusting relationship between Marlene and the nurse, as Marlene feels safe and supported enough to disclose sensitive information. Building trust is a crucial aspect of any professional relationship, especially in healthcare settings, as it fosters open communication, encourages honesty, and ultimately leads to better outcomes for the patient. It is an essential foundation for providing effective care and support to individuals in need.

Correct Answer: C

Rationale: The nurse should prioritize removing the old dressing and applying a new dressing using sterile technique to minimize the risk of infection during a central venous catheter (CVC) dressing change. This is because the most critical step in preventing infection is maintaining a clean and sterile environment around the CVC insertion site. By using sterile technique, the nurse can reduce the introduction of microorganisms that could potentially lead to infection. Wearing sterile gloves and cleaning the insertion site with an alcohol-based antiseptic solution are important steps as well, but the key priority lies in applying the new dressing using sterile technique to prevent contamination and reduce the risk of infection.

Correct Answer: B

Rationale: The scenario described in the question is most indicative of endometriosis. Endometriosis is a gynecological condition in which tissue similar to the lining of the uterus grows outside of the uterus. Classic symptoms of endometriosis include cyclic pelvic pain, dysmenorrhea (painful periods), and infertility. The presence of a "chocolate cyst" (also known as an endometrioma) within the ovary on pelvic ultrasound is a characteristic finding in endometriosis. These cysts are filled with old blood, giving them a dark, chocolate-like appearance on imaging. Polycystic ovary syndrome (PCOS) typically presents with irregular periods, signs of hyperandrogenism, and multiple small follicles on ultrasound. Ovarian torsion and ovarian cyst rupture would present with acute-onset symptoms and may not necessarily be associated with cyclic pelvic pain and dysmenorrhea as described in the
