After a few hours in the Emergency Room, Mr. Dizon is admitted to the ward with an order of hourly monitoring of blood pressure. The nurse finds that the cuff is too narrow and this will cause the blood pressure reading to be:

Correct Answer: C

Rationale: In this scenario, the correct answer is option C) higher than what the reading should be. When the blood pressure cuff is too narrow for the patient's arm circumference, it will result in increased resistance to blood flow, leading to a falsely elevated blood pressure reading. This occurs because the cuff exerts excessive pressure on the artery, causing an artificial constriction that does not reflect the true blood pressure. Option A) inconsistent is incorrect because the reading will consistently be higher due to the cuff size issue. Option B) low systolic and high diastolic is incorrect as a narrow cuff typically leads to an overestimation of both systolic and diastolic pressures. Option D) lower than what the reading should be is also incorrect in this case. Educationally, understanding the importance of using the correct size blood pressure cuff is crucial in obtaining accurate blood pressure measurements. Incorrect cuff size can lead to misdiagnosis, unnecessary treatments, or inappropriate adjustments in medication dosages. Healthcare professionals must ensure proper cuff selection based on the patient's arm size to obtain precise blood pressure readings for accurate clinical assessment and treatment decisions.

Correct Answer: C

Rationale: In the context of pharmacology and medical practice, understanding the importance of endotracheal (ET) tubes is crucial for healthcare professionals. The GAUGE size of an ET tube specifically determines the length of the tube. This is because the GAUGE size refers to the diameter of the tube. The correct answer, option C, is the length of the tube because GAUGE size is a measurement of the diameter, not the circumference or volumetric capacity. The diameter of the tube is a critical factor in ensuring proper ventilation and airway management for patients requiring intubation. Option A, the external circumference of the tube, is incorrect because GAUGE size does not pertain to the external measurement but rather the internal diameter. Option B, the internal diameter of the tube, is partially correct in concept but the question specifically asks for what the GAUGE size determines, which is the length of the tube, making option B incorrect. Understanding the specifics of ET tube sizing is essential for healthcare professionals to effectively select the appropriate tube for patient care. It ensures proper airway management and ventilation, contributing to positive patient outcomes in clinical settings.

Correct Answer: D

Rationale: In the context of an emergency like a fire breaking out in a unit, the best leadership style suited is Laissez-Faire (Option D). This is because in such critical situations where immediate action is needed, a Laissez-Faire approach allows individuals on the team to take quick decisions and act autonomously without waiting for explicit instructions. This can be crucial in ensuring swift and effective responses to the emergency. Autocratic leadership (Option A) may not be suitable in this scenario as it involves a top-down approach where the leader makes decisions without input from others. In emergencies, quick thinking and collaboration are often essential, which an autocratic style may hinder. Participative (Option B) and Democratic (Option C) leadership styles involve more collaboration and input from team members, which may not be practical in a time-sensitive emergency where immediate actions are needed. These styles could slow down decision-making processes and impede quick responses to the crisis at hand. In an educational context, understanding different leadership styles and their appropriate applications in various situations, including emergencies, is crucial for healthcare professionals like nurses. By knowing when to adopt a Laissez-Faire approach in emergencies, nurses can effectively lead their teams and respond promptly to critical situations, ensuring the safety and well-being of patients and staff.

Correct Answer: B

Rationale: In this scenario, the correct answer is B) Stay with Mang Carlos and do nothing. This is the appropriate action because Mang Carlos has a standing Do Not Resuscitate (DNR) order in place. A DNR order means that the individual has made the decision to not receive life-saving measures in the event of cardiac or respiratory arrest. By honoring the DNR order, you are respecting Mang Carlos' autonomy and wishes regarding his end-of-life care. Option A) Give extraordinary measures to save Mang Carlos goes against his expressed wishes and the DNR order he has in place. Administering life-saving measures would be unethical and a violation of his autonomy. Option C) Call the physician is not the correct action in this situation because the standing DNR order takes precedence over contacting the physician. The DNR order is a clear directive that should be followed immediately in the event of a medical emergency. Option D) Activate Code Blue is also not the appropriate response because it would initiate a full resuscitation protocol, which is contrary to the DNR order. Activating a Code Blue would result in medical interventions that Mang Carlos has explicitly declined. This scenario underscores the importance of understanding and respecting patients' advance directives, such as DNR orders. Healthcare providers must be knowledgeable about these directives and be prepared to act in accordance with them to uphold patient autonomy and dignity, even in challenging situations like this one.

Correct Answer: B

Rationale: In the study on the "effects of effective nurse-patient communication in decreasing anxiety of postoperative patients," the dependent variable is "Anxiety level" (Option C). The dependent variable is the outcome that is being measured or observed in an experiment or study. In this case, the researchers are investigating how nurse-patient communication affects the anxiety levels of postoperative patients. Therefore, anxiety level is the variable that is dependent on the level of nurse-patient communication. Option A, "Effective Nurse-patient communication," is incorrect as it is the independent variable in this study, meaning it is the variable that is being manipulated or controlled by the researchers to observe its effect on the dependent variable. Option B, "Communication," is too broad and does not specify the specific aspect of communication that is being measured in the study. It is not the specific outcome variable of interest. Option D, "Postoperative patient," is also incorrect as it is not the variable being measured but rather the population or group being studied. Understanding the distinction between dependent and independent variables is crucial in research and pharmacology as it helps in designing experiments, analyzing results, and drawing meaningful conclusions about the relationship between variables. By correctly identifying the dependent variable, researchers can determine the effectiveness of interventions and make informed decisions in clinical practice to improve patient outcomes.
