A nurse is caring for a patient who expresses concerns about the potential side effects of a prescribed medication. What action should the nurse take to address the patient's concerns?

Correct Answer: B

Rationale: The nurse should provide accurate information about the medication, including potential side effects, to address the patient's concerns. It is important for the nurse to listen to the patient's worries and provide them with the knowledge they need to make an informed decision about their treatment. By educating the patient about the medication and its potential side effects, the nurse empowers the patient to be actively involved in their care and promotes shared decision-making. Disregarding the patient's concerns, encouraging them to stop taking the medication, or minimizing the importance of their worries are not appropriate responses and may negatively impact the patient-nurse relationship and the patient's adherence to the prescribed treatment.

Correct Answer: D

Rationale: Using aseptic technique and sterile equipment during catheter insertion is crucial for minimizing the risk of infection during bladder catheterization. Aseptic technique involves maintaining a sterile field, washing hands thoroughly, using sterile gloves, and ensuring that all equipment used is sterile. By following these practices, the nurse can prevent introducing bacteria into the urinary tract, reducing the likelihood of infection in the patient. While cleansing the perineal area with antiseptic solutions is important for general hygiene, the priority for infection prevention during catheterization lies in maintaining a sterile environment during the procedure. Administering prophylactic antibiotics is not routinely recommended for catheterization unless there are specific risk factors present.

Correct Answer: B

Rationale: The most critical action to prioritize for ensuring patient safety during a cardiopulmonary exercise stress test is to monitor the patient's electrocardiogram (ECG) rhythm continuously during the test (Option B). This monitoring allows the healthcare team to promptly detect any abnormal heart rhythms or signs of cardiac distress, enabling timely intervention if necessary. Continuous ECG monitoring is essential during exercise testing as it helps in assessing the heart's response to physical activity and identifying any potential cardiac abnormalities or complications that may arise during the test. By closely monitoring the ECG rhythm, the nurse can ensure the patient's safety and well-being throughout the procedure. Administering a beta-blocker medication before the test (Option A) may be indicated in some cases but is not as crucial as continuous ECG monitoring during the test. Encouraging the patient to consume a heavy meal before the test (Option C) is contraindicated as it can interfere with the accuracy of the results

Correct Answer: A

Rationale: The described presentation of a pruritic, annular rash with central clearing and a raised, scaly border that spreads outward in a centrifugal pattern is characteristic of tinea corporis, commonly known as ringworm. This fungal infection affects the skin and is typically ring-shaped, with a well-defined, slightly raised, and scaly border. The central area often clears as the lesion enlarges peripherally, resembling a ring. It is important to note that ringworm is not caused by a worm but by a fungus. Treatment typically involves antifungal medications applied topically or taken orally, depending on the severity of the infection.

Correct Answer: B

Rationale: Molluscum contagiosum is a viral skin infection caused by the poxvirus. It typically presents as multiple dome-shaped, translucent papules with central umbilication on the face and trunk. The lesions are usually asymptomatic but can be itchy. Molluscum contagiosum is a common infection in children but can also occur in adults, especially those who are immunocompromised. The lesions can gradually increase in number over time. Basal cell carcinoma, sebaceous hyperplasia, and keratoacanthoma do not typically present with the characteristic features of molluscum contagiosum.
