Correct Answer: A

Rationale: The presentation of well-demarcated, hypopigmented macules with fine scaling on the trunk and proximal extremities is classic for tinea versicolor. Tinea versicolor is a common superficial fungal infection caused by Malassezia spp., which leads to hypo- or hyperpigmented patches on the skin. The condition often occurs in individuals with increased sebum production due to factors such as hot and humid climates, sweating, and oily skin. History of sun exposure and outdoor activities is also commonly reported by patients with tinea versicolor. Treatment usually involves antifungal medications applied topically or taken orally to eliminate the fungus. Differentiating tinea versicolor from other skin conditions, such as vitiligo, pityriasis rosea, or seborrheic keratosis, is important for appropriate management.

Correct Answer: A

Rationale: Placing the mother in a hands-and-knees position can help facilitate fetal rotation from occiput posterior to the desired occiput anterior position. This position utilizes gravity to assist in the repositioning of the baby, ultimately helping to alleviate back pain and promoting more efficient labor progress. It allows the baby's head to descend properly into the pelvis, potentially reducing the risk of a prolonged labor or the need for instrumental delivery. Additionally, being in this position can help the mother feel more comfortable and empowered during labor. Overall, assisting the mother into a hands-and-knees position is a non-invasive, low-risk intervention that can have a positive impact on both the mother and baby's well-being during labor.

Correct Answer: B

Rationale: In an educational program conducted by a nurse, it is crucial to involve the patient, their family, and significant others. This approach ensures holistic care by considering the patient's psychosocial environment, family dynamics, and support system. Including these individuals in the educational program fosters collaboration, strengthens the patient-nurse relationship, and equips family members with the knowledge and skills needed to provide optimal care at home. Furthermore, involving the patient's support system can enhance adherence to treatment plans and contribute to better health outcomes. Therefore, the presence and cooperation of the patient, family, and significant others are essential elements of a successful educational program led by a nurse.

Correct Answer: B

Rationale: Beta-blockers work by blocking the effects of adrenaline on beta receptors in the body. One common adverse effect of beta-blockers is bradycardia, or a slowed heart rate. Since the patient is being prescribed a beta-blocker for migraine headaches, it is important for the nurse to monitor closely for signs and symptoms of bradycardia such as dizziness, fatigue, and fainting. Monitoring the heart rate regularly and reporting any significant decrease to the healthcare provider is essential to prevent complications associated with bradycardia. Compared to the other options, bradycardia is the most relevant adverse effect to monitor in a patient prescribed a beta-blocker.

Correct Answer: B

Rationale: The positive practice environment (PPE) in a health care setting typically includes components such as waste management, infection control, and peer review. However, electrical wires are not a standard component of the PPE in a work setting. Electrical safety is important in a healthcare facility, but it is usually addressed in a separate set of guidelines and protocols focusing specifically on electrical safety and maintenance. Therefore, among the given options, electrical wires are not considered a component of the positive practice environment in the work setting.
