A patient presents with well-demarcated, hypopigmented macules with fine scaling, affecting the trunk and proximal extremities. The patient reports a history of sun exposure and outdoor activities. Which of the following conditions is most likely responsible for this presentation?

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: B

Rationale: One of the signs and symptoms of Benign Prostatic Hyperplasia (BPH) is not pain on urination. BPH is a non-cancerous enlargement of the prostate gland which can cause urinary symptoms such as frequency of urination, dribbling of urine, hesitancy in starting urination, weak urine flow, feeling of incomplete bladder emptying, and increased urination at night (nocturia). Pain on urination is not typically associated with BPH, and it may suggest other urinary tract issues such as a urinary tract infection or a different medical condition.

Correct Answer: C

Rationale: The most effective strategy in preventing more incidence of dengue infection is to target the breeding places of the Aedes mosquitoes, which are the vectors responsible for transmitting the dengue virus. By eliminating stagnant water sources where these mosquitoes breed, such as uncovered containers, flower pots, and discarded tires, the mosquito population can be significantly reduced. This, in turn, helps to lower the risk of dengue transmission to humans. While healthy nutritious food, burning of leaves and garbage, and adequate rest and sleep are important for overall health and immune function, they do not directly address the primary cause of dengue transmission, which is the Aedes mosquito population.

Correct Answer: D

Rationale: Public Health Nursing is a specialized field of nursing that focuses on promoting and protecting the health of populations and communities rather than individuals. One of the key principles of Public Health Nursing is the emphasis on health promotion and disease prevention strategies. This involves educating and empowering individuals, families, and communities to adopt healthy behaviors and lifestyles in order to prevent illness and improve overall well-being. Public Health Nurses work to address the root causes of health disparities and advocate for policies and programs that promote the health of entire populations. While providing care to sick individuals may be a component of Public Health Nursing, the primary focus is on preventing illness and promoting health at the community level.

Correct Answer: D

Rationale: The most appropriate oxygen delivery device for a patient with chronic respiratory failure secondary to severe restrictive lung disease requiring continuous supplemental oxygen is a non-rebreather mask. A non-rebreather mask is designed to deliver high-flow oxygen and is typically used for short-term medical treatment in emergency situations or for critically ill patients. It is ideal for providing the highest concentration of oxygen available for inhalation, making it suitable for patients with severe hypoxemia.

Correct Answer: B

Rationale: Assisting the client to a seated position on the toilet should be implemented first. This position promotes relaxation of the pelvic floor muscles and can help facilitate urinary elimination. It is a non-invasive and least intrusive intervention compared to performing intermittent catheterization or administering diuretic medication. Encouraging the client to drink plenty of fluids is important for promoting overall urinary function, but in this case, the priority is to aid the client in attempting to void first.

Correct Answer: A

Rationale: The primary intervention that should be prioritized for managing a catheter-related bloodstream infection (CRBSI) associated with a central venous catheter is to remove the central venous catheter. CRBSI is a serious complication that can lead to severe infections and sepsis. The removal of the catheter is crucial to eliminate the source of the infection and prevent further dissemination of the pathogens into the bloodstream. Once the catheter is removed, the healthcare team can consider other interventions such as administering targeted antibiotics based on culture results, performing blood cultures to identify the causative organism, and implementing sterile dressing changes and catheter care protocols. However, immediate removal of the catheter takes precedence in managing CRBSI to prevent worsening of the infection and improve patient outcomes.

Correct Answer: C

Rationale: The health care team will try the oral route first for Ms. C for delivering nutrition and fluid because it is the most natural and least invasive method. If the patient is able to tolerate oral intake and has adequate oral intake, it is typically the preferred route. Only if she is unable to meet her nutritional needs orally or has difficulty swallowing, then alternative routes such as nasogastric tube, gastrostomy tube, or intravenous routes may be considered. It's important to promote oral intake whenever possible to maintain the patient's quality of life and prevent complications associated with more invasive methods.

Correct Answer: C

Rationale: Calcium is essential for maintaining strong and healthy bones. Osteoporosis is a condition characterized by weakened bones, making them more prone to fractures. Consuming calcium-rich foods such as dairy products, leafy greens, and fortified foods can help prevent osteoporosis development. Additionally, incorporating calcium supplements under the guidance of a healthcare provider can further support bone health and reduce the risk of osteoporosis. Regular intake of adequate calcium is considered a crucial preventive measure for osteoporosis.
