Correct Answer: D

Rationale: The correct answer is D because the licensure examination aims to assess if candidates meet the expected competency standards to practice nursing safely and effectively. This process ensures that only qualified individuals enter the profession, maintaining high standards of care. Choice A is incorrect because the exam goes beyond applying theory to include practical skills. Choice B is incorrect as protecting the public is the outcome of ensuring competency. Choice C is incorrect as the exam evaluates the full scope of nursing practice, not just its application.

Correct Answer: B

Rationale: The correct answer is B: pulse rates. Pulse rates can be analyzed on the ratio level of measurement because they have a true zero point and allow for meaningful ratios to be calculated. This means that we can perform operations such as addition, subtraction, multiplication, and division on pulse rate data. In contrast, the other options (A: eye color, C: ethnicity, D: gender) are categorical data that do not have a true zero point and therefore cannot be analyzed on the ratio level. Eye color, ethnicity, and gender are all examples of nominal data which only allow for qualitative classification and do not have a numerical value that can be used in mathematical operations.

Correct Answer: A

Rationale: The correct answer is A: Initiate non-invasive positive pressure ventilation (NIPPV). This intervention is prioritized as it helps improve oxygenation and ventilation in COPD exacerbation without the need for invasive mechanical ventilation, reducing the risk of ventilator-associated complications. NIPPV also decreases the work of breathing and can prevent the need for intubation. Administering bronchodilator medications (B) is important in COPD exacerbation but may not address the immediate need for ventilatory support. Endotracheal intubation (C) should be reserved for cases of respiratory failure not responding to NIPPV. Chest physiotherapy (D) may be beneficial in some cases but is not the first-line intervention for managing acute COPD exacerbation.

Correct Answer: A

Rationale: The correct answer is A: Identify and count cases. In the initial stages of an outbreak investigation, it is crucial to identify and count cases to understand the scope and magnitude of the outbreak. By counting cases, Nurse Rona and her team can track the spread of the disease, identify common characteristics among those affected, and determine the extent of the outbreak. This step helps in guiding further investigation and control measures. Summary of other choices: B: Define and identify cases - While defining cases is important, it is not the initial step in outbreak investigation. C: Verify diagnosis - Verifying diagnosis is important but comes after identifying and counting cases. D: Prepare for field work - Field work is important in outbreak investigations, but it typically comes after the initial step of identifying and counting cases.

Correct Answer: D

Rationale: The correct answer is D, Broad opening. Nurse Rica should use this communication technique to encourage the patient to freely express themselves without leading or interrupting. This technique helps build rapport and trust, setting a positive tone for the conversation. A: Clarifying may be too direct and might make the patient feel pressured. B: Challenging can create defensiveness and hinder open communication. C: Restating may not be as effective in initiating a conversation as broad opening. In summary, broad opening allows for a more open and relaxed conversation, fostering a conducive environment for effective communication with the patient.
