Which of the following structures is responsible for transporting food from the oral cavity to the esophagus during swallowing?
- A. Tongue
- B. Pharynx
- C. Esophagus
- D. Epiglottis
Correct Answer: B
Rationale: The pharynx is the structure responsible for transporting food from the oral cavity to the esophagus during swallowing. When food is chewed and mixed with saliva in the oral cavity, it forms a bolus that is propelled to the pharynx by the tongue. The pharynx serves as a common passageway for both air and food, allowing the bolus to pass into the esophagus while preventing it from entering the trachea. The epiglottis, although important in preventing food from entering the airway, is not directly involved in the transportation of food from the oral cavity to the esophagus.

With diagnosis of hemorrhagic stroke, the nurse teaches the caregiver that with position of the bed should be in what position?
- A. High-Fowler's
- B. Prone
- C. Fowler
- D. Flat
Correct Answer: A
Rationale: For a patient diagnosed with a hemorrhagic stroke, the caregiver should ensure that the bed is positioned in a High-Fowler's position. This position involves elevating the head of the bed between 60 to 90 degrees. Elevating the head of the bed helps to reduce intracranial pressure and promote optimal cerebral perfusion. It also assists in maintaining proper ventilation and oxygenation, which are essential for the patient's recovery. It is important to avoid positioning the patient flat or in a prone position as these may exacerbate the condition and lead to further complications.
A patient presents with gross hematuria, flank pain, and a palpable abdominal mass. Imaging reveals a large heterogeneous renal mass with areas of necrosis and calcifications. Which of the following conditions is most likely?
- A. Renal cell carcinoma
- B. Renal cyst
- C. Renal abscess
- D. Renal angiomyolipoma
Correct Answer: A
Rationale: The clinical presentation of gross hematuria, flank pain, palpable abdominal mass, along with imaging findings of a large heterogeneous renal mass with necrosis and calcifications are highly suggestive of renal cell carcinoma (RCC). RCC is the most common type of kidney cancer in adults. The presence of necrosis and calcifications are characteristic features of RCC. Imaging modalities such as CT scans or MRI can confirm the diagnosis by showing the typical features of RCC, including a solid mass with areas of necrosis and calcifications. It is important to further evaluate this patient, likely with a biopsy, to confirm the diagnosis and determine the extent of the disease for appropriate management.
Which of the following terms refers to the process by which antibodies coat the surface of pathogens, marking them for destruction by phagocytes or complement proteins?
- A. Opsonization
- B. Neutralization
- C. Agglutination
- D. Precipitation
Correct Answer: A
Rationale: Opsonization refers to the process by which antibodies bind to the surface of pathogens, marking them for destruction by phagocytes or complement proteins. This coating of antibodies enhances the ability of the immune system to recognize and eliminate the pathogens effectively. Phagocytes (such as macrophages and neutrophils) are better able to engulf and digest pathogens that have been opsonized, as the antibodies attached to the pathogen surface signal to the phagocytes that they are foreign invaders. This process is crucial in the body's immune response to infections and helps in clearing pathogens from the system.
Which is the best strategy to control Incidence of Rabies in the community
- A. Impound dogs
- B. Kill stray dogs
- C. Responsible pet owner
- D. Fine the owner
Correct Answer: C
Rationale: The best strategy to control the incidence of rabies in the community is to promote responsible pet ownership. Responsible pet owners ensure that their pets are vaccinated against rabies, kept on a leash or within a confined area, and are not allowed to roam freely. By doing so, the chances of their pets contracting and spreading rabies are greatly reduced. This approach focuses on prevention rather than reactive measures such as impounding or killing dogs, which may not effectively tackle the root cause of the problem. Additionally, fining the owner may serve as a deterrent, but it does not address the overall issue of preventing rabies transmission. Encouraging responsible pet ownership is a sustainable and humane way to reduce the incidence of rabies in the community.
Right after endorsement and during the rounds, the incoming nurse observes that the IV fluid is at 800 cc level and not 400cc, as endorsed. What is the CORRECT information that she will chart?
- A. Anything goes, nobody reads the charting anyway.
- B. Record the 400 cc.
- C. Chart that she received 800
- D. Refer to the Head Nurse on what to do.
Correct Answer: C
Rationale: The correct information that the incoming nurse should chart is that she received 800 cc of IV fluid. It is crucial for the charting to accurately reflect the actual situation to provide an accurate record for the patient's care. In this scenario, the discrepancy between the endorsed amount (400 cc) and the observed amount (800 cc) should be documented to ensure transparency and continuity of care. This deviation from the expected amount should be clearly recorded for proper monitoring and evaluation of the patient's condition.
