Correct Answer: B

Rationale: When a patient is unable to talk, the nurse can best communicate with the patient by using picture cards. Picture cards can help the patient convey their needs, feelings, or responses by pointing to the corresponding pictures. This method allows for effective communication and understanding between the patient and the nurse, even when verbal communication is not possible. It promotes patient autonomy and ensures that their needs are accurately communicated and addressed. Additionally, picture cards can be a useful tool in reducing frustration and anxiety for patients who are unable to communicate verbally.

Correct Answer: B

Rationale: The ethical principle of autonomy emphasizes respecting the patient's right to make their own decisions regarding their treatment. In this scenario, the patient has the right to refuse treatment, and the nurse should respect that decision while also providing information and guidance to help the patient make informed choices. By upholding the principle of autonomy, the nurse can support the patient's decision-making process and work collaboratively with them to address any concerns or barriers to compliance with the treatment regimen. This approach honors the patient's right to self-determination and promotes a trusting relationship between the nurse and the patient.

Correct Answer: C

Rationale: When the nurse collects data at one point in time, it is referred to as a cross-sectional study. Cross-sectional studies are observational research designs that provide a snapshot of a population or a sample at a specific point in time. This type of study can help identify associations or relationships between variables at a single time point but cannot establish causality or determine changes over time. In contrast, time series involve collecting data over multiple time points, longitudinal studies follow individuals or samples over time to track changes or outcomes, and crossover studies involve multiple interventions or treatments over different periods.

Correct Answer: C

Rationale: In the case of Mang Luis, who has been diagnosed with chronic obstructive pulmonary disease (COPD) and is experiencing exacerbation, the most crucial health intervention to include in the teaching plan is to reduce the risk for infection. COPD exacerbations are commonly triggered by respiratory infections such as pneumonia and bronchitis. Preventing infections is essential in managing COPD as they can lead to worsening of symptoms and increased healthcare utilization. Therefore, educating Mang Luis on strategies to reduce the risk of infection, such as proper hand hygiene, avoiding exposure to sick individuals, getting vaccinated, and managing environmental factors, is paramount in his care plan.

Correct Answer: C

Rationale: When a postpartum client exhibits signs of wound infection, such as erythema, warmth, and purulent drainage from a cesarean incision, it is essential to notify the healthcare provider immediately. Wound infections can lead to serious complications if not promptly addressed. The healthcare provider will assess the infection, possibly order further diagnostic tests, and determine the appropriate course of treatment, which may include antibiotics or additional wound care measures. Applying a dressing or irrigating the wound may be part of the treatment plan prescribed by the healthcare provider, but the first step is always to seek guidance from the provider.
