Which of the following structures is responsible for propelling food from the oral cavity to the stomach through coordinated muscular contractions?
- A. Tongue
- B. Pharynx
- C. Esophagus
- D. Epiglottis
Correct Answer: C
Rationale: The esophagus is responsible for propelling food from the oral cavity to the stomach through a series of coordinated muscular contractions. These contractions are known as peristalsis. The esophagus is a muscular tube connecting the throat (pharynx) to the stomach and plays a crucial role in moving food bolus from the mouth to the stomach for digestion. The tongue helps in the chewing and swallowing of food, the pharynx is involved in the passage of food and air, and the epiglottis helps prevent food from entering the airways during swallowing. However, it is the esophagus that actively moves the food to the stomach.

A patient presents with chest pain, dyspnea, and signs of hypotension. An echocardiogram reveals right ventricular dilation and hypokinesis. Which cardiovascular disorder is most likely responsible for these symptoms?
- A. Pulmonary embolism
- B. Pericardial effusion
- C. Acute myocardial infarction
- D. Aortic dissection
Correct Answer: A
Rationale: The presentation of chest pain, dyspnea, hypotension, right ventricular dilation, and hypokinesis on echocardiogram is highly suggestive of a pulmonary embolism. In pulmonary embolism, a blood clot obstructs the pulmonary artery or one of its branches, leading to increased pressure in the right ventricle, which can cause right ventricular dilation and dysfunction. This results in the classic signs of right heart strain on echocardiogram. The patient may also present with symptoms of acute right heart failure, such as chest pain, dyspnea, and signs of hypotension. It is crucial to consider pulmonary embolism as a potential cause of these symptoms, given the high morbidity and mortality associated with this condition.
Which IMPORTANT Information the nurse should inform the public about rabies?
- A. It could be prevented
- B. It is an ordinary disease
- C. Rabies is not deadly
- D. It kills
Correct Answer: A
Rationale: The nurse should inform the public that rabies can be prevented. This is an extremely important piece of information to help raise awareness about the disease and promote preventive measures such as timely vaccination of both animals and humans. Rabies is a deadly viral infection that affects the central nervous system, and prevention through vaccination is highly effective in controlling its spread. By emphasizing the preventability of rabies, the nurse can educate the public on the importance of taking proactive steps to avoid contracting the disease.
A nurse is caring for a patient with limited English proficiency. What action should the nurse take to ensure effective communication with the patient?
- A. Speak loudly and slowly to help the patient understand
- B. Use medical jargon to convey information more efficiently
- C. Obtain interpreter services or language assistance as needed
- D. Ignore the patient's language barriers and focus on nonverbal communication
Correct Answer: C
Rationale: The nurse should obtain interpreter services or language assistance as needed to ensure effective communication with a patient who has limited English proficiency. Using an interpreter will facilitate clear and accurate communication between the nurse and the patient, enabling the patient to fully understand their care, treatment, and any instructions provided. Speaking loudly or slowly, using medical jargon, or ignoring the language barriers are not effective strategies for communicating with a patient who has limited English proficiency. Utilizing interpreter services demonstrates respect for the patient's language and cultural needs, which is essential for providing high-quality care.
Which of the following research designs is MOST APPROPRIATE for this study if the aim is to find a relationship between two variables in the study?
- A. Phenomenological study
- B. Exploratory
- C. Experimental
- D. Correlational
Correct Answer: D
Rationale: A correlational research design is most appropriate when the aim is to find a relationship between two variables. Correlational studies examine how variables are related to each other without manipulating them. This design allows researchers to determine the strength and direction of the relationship between variables, providing valuable insights into the potential associations between different factors. Phenomenological studies focus on understanding individuals' experiences, exploratory studies investigate a topic without predefined hypotheses, and experimental studies involve manipulating variables to observe their effects. Therefore, in the context of aiming to find a relationship between two variables, a correlational research design is the most suitable choice.
When Nurse Sarah distributed a Patient satisfaction' survey form to be filled by the consumer upon discharge in a hospital setting is in compliance to what quality standards?
- A. Organizational structure and professional ethics.
- B. Identification of Patient right and welfare.
- C. Improving performance, of health care personnel.
- D. Human resource management and staffing pattern.
Correct Answer: B
Rationale: When Nurse Sarah distributed a Patient satisfaction survey form to be filled by the consumer upon discharge in a hospital setting, it aligns with the quality standard of identifying Patient rights and welfare. Patient satisfaction surveys aim to gather feedback from patients about their experiences with the health care services provided. By distributing such surveys, the hospital is demonstrating its commitment to ensuring the rights and welfare of patients by seeking their feedback, understanding their concerns, and incorporating their suggestions for improvement. This initiative helps in enhancing the quality of care provided to patients and ultimately contributes to improving overall patient outcomes and satisfaction.
