Rationale: ORNAP stands for Operating Room Nurses Association of the Philippines. As Merle has been assigned in the Operating Room for 3 years and is interested in actively joining a professional organization related to this field, ORNAP would be the most appropriate choice. ORNAP focuses on promoting excellence in perioperative nursing practice through education, research, and collaboration. By joining ORNAP, Merle can further enhance her knowledge and skills in the Operating Room setting, as well as network with other professionals in the same field.

Correct Answer: B

Rationale: Enamel hypoplasia is a common oral manifestation of celiac disease characterized by defects in the enamel of the teeth. These defects can appear as horizontal or vertical grooves on the teeth. Enamel hypoplasia is caused by disruptions in the formation of enamel during tooth development, leading to thin enamel or localized pitting. It can affect the appearance and strength of the teeth, making them more prone to sensitivity and breakdown. In individuals with celiac disease, enamel hypoplasia may occur due to malabsorption of essential nutrients like calcium and vitamin D. Therefore, when observing oral manifestations such as enamel defects with grooves, it is important to consider the possibility of celiac disease as an underlying cause.

Correct Answer: B

Rationale: The nurse's best approach to address a patient's concerns about the potential side effects of a prescribed medication is to provide the patient with accurate information about potential side effects and management strategies. It is important for the nurse to acknowledge the patient's concerns, listen attentively, and offer clear explanations to help alleviate any fears or uncertainties. Providing accurate information can empower the patient to make informed decisions about their healthcare and feel more confident in taking the prescribed medication. Dismissing or ignoring the patient's concerns can lead to mistrust and non-adherence to the treatment plan. It is essential for the nurse to prioritize open communication and patient education to ensure the patient's well-being and compliance with the prescribed medication regimen.

Correct Answer: C

Rationale: In the early stages of multiple myeloma (MM), abnormal values are often seen in the levels of immunoglobulins. This is due to the abnormal proliferation of plasma cells in the bone marrow, leading to overproduction of monoclonal immunoglobulins (M proteins). These abnormal immunoglobulins can be detected in blood tests and are a key diagnostic feature of MM. Changes in red blood cells, white blood cells, and platelets are not typically early indicators of multiple myeloma.

Correct Answer: C

Rationale: Opioid analgesics are known to suppress the respiratory centers in the brain, leading to respiratory depression as a side effect. This adverse effect is particularly dangerous and potentially life-threatening, especially in patients who are opioid-naive or when high doses are administered. Therefore, it is crucial for the nurse to closely monitor the patient's respiratory rate, depth, and effort while on opioid analgesic therapy to detect early signs of respiratory depression and intervene promptly to prevent complications. Hypertension, hypoglycemia, and hyperkalemia are not commonly associated with opioid analgesics.
