Which of the following dental conditions is characterized by a localized collection of pus resulting from a bacterial infection of the tooth pulp?
- A. Dental caries
- B. Periodontitis
- C. Dental abscess
- D. Oral candidiasis
Correct Answer: C
Rationale: A dental abscess is characterized by a localized collection of pus that results from a bacterial infection of the tooth pulp, leading to swelling, pain, and inflammation. The infection typically occurs when bacteria enter the tooth through a cavity, crack, or other dental injury. The abscess can cause significant pain and discomfort and must be treated promptly by a dentist to prevent further complications. Dental caries refer to tooth decay or cavities that result from the breakdown of tooth structure by acids produced by bacteria. Periodontitis is a severe gum infection that damages the soft tissue and destroys the bone that supports the teeth. Oral candidiasis is a fungal infection that affects the mouth and throat.

Patient Haydee comes to the perinatal unit of Hospital DEE. Nurse Arcee does through SCREENING assessment. Which is the Least screening assessment to be used by the nurse/
- A. Physical examination
- B. Radiologic procedures
- C. Interview
- D. Laboratory review
Correct Answer: B
Rationale: Radiologic procedures are typically not used as the least screening assessment by nurses in a perinatal unit. The nurse's initial screening assessments usually focus on gathering information through techniques such as physical examination, interviews, and reviewing laboratory results. Radiologic procedures, such as X-rays or CT scans, are usually ordered by physicians once a more specific diagnostic need has been identified, based on the initial screening assessments performed by the nurse. Therefore, in this scenario, the least screening assessment to be used by the nurse would be radiologic procedures.
A patient presents with gradual-onset weakness, spasticity, hyperreflexia, and positive Babinski sign. Imaging reveals demyelinating plaques in the white matter of the brain and spinal cord. Which of the following neurological conditions is most likely responsible for these symptoms?
- A. Amyotrophic lateral sclerosis (ALS)
- B. Multiple sclerosis (MS)
- C. Guillain-Barré syndrome (GBS)
- D. Myasthenia gravis
Correct Answer: B
Rationale: The symptoms described - gradual-onset weakness, spasticity, hyperreflexia, positive Babinski sign, and demyelinating plaques in the white matter of the brain and spinal cord - are indicative of multiple sclerosis (MS). MS is an autoimmune disease where the body's immune system attacks the myelin sheath, leading to the formation of plaques in the central nervous system. The characteristic symptoms of MS include weakness, spasticity (stiffness in muscles), hyperreflexia (exaggerated reflex responses), and positive Babinski sign (upward movement of the big toe). While ALS (Amyotrophic lateral sclerosis) presents with progressive muscle weakness and atrophy without sensory involvement and demyelinating plaques, Guillain-Barré syndrome (GBS) is typically an acute inflammatory demyelinating polyneuropathy affecting peripheral nerves rather than the central nervous system, and myast
Which of the following actions is appropriate for managing a conscious patient with a suspected stroke?
- A. Administering aspirin immediately.
- B. Placing the patient in a supine position.
- C. Encouraging the patient to eat and drink.
- D. Activating emergency medical services (EMS) for rapid transport to a stroke center.
Correct Answer: D
Rationale: Activating emergency medical services (EMS) for rapid transport to a stroke center is the most appropriate action for managing a conscious patient with a suspected stroke. Time is critical in stroke care, and receiving specialized treatment at a stroke center as soon as possible can significantly improve outcomes for stroke patients. EMS providers are trained to recognize the signs of stroke and can begin essential pre-hospital care measures while en route to the hospital. Administering aspirin immediately is not recommended without medical evaluation, as certain types of strokes (such as hemorrhagic strokes) can be worsened by aspirin. Placing the patient in a supine position may not be ideal, as maintaining an elevated position can help prevent aspiration in stroke patients. Encouraging the patient to eat and drink is not appropriate, as swallowing difficulties are common in stroke patients and can lead to aspiration pneumonia.
A patient with a history of heart failure presents with dependent edema in the lower extremities. Which nursing action is most appropriate for managing the patient's edema?
- A. Applying compression stockings
- B. Elevating the legs above heart level
- C. Administering diuretics as prescribed
- D. Encouraging increased fluid intake
Correct Answer: C
Rationale: The most appropriate nursing action for managing a patient with dependent edema in the lower extremities is to administer diuretics as prescribed. Diuretics help the body remove excess fluid, reducing swelling and edema in the extremities. It is important to follow the healthcare provider's orders for administering diuretics to ensure the patient's fluid balance is managed effectively. While elevating the legs above heart level and applying compression stockings may provide temporary relief, addressing the underlying cause of fluid retention with diuretics is essential for long-term management of the edema in a patient with heart failure. Encouraging increased fluid intake would not be appropriate in this case, as the focus should be on reducing fluid overload rather than increasing fluid intake.
Which of the following dental conditions is characterized by inflammation and destruction of the supporting structures of the teeth, including the gingiva, periodontal ligament, and alveolar bone?
- A. Dental caries
- B. Gingivitis
- C. Periodontitis
- D. Dental abscess
Correct Answer: C
Rationale: Periodontitis is the dental condition characterized by inflammation and destruction of the supporting structures of the teeth, including the gingiva (gums), periodontal ligament, and alveolar bone. It is usually caused by untreated gingivitis, where plaque buildup along the gumline leads to bacterial infection and inflammation, resulting in destruction of the tissues that support the teeth. If left untreated, periodontitis can lead to tooth loss and other complications. Gingivitis, on the other hand, is inflammation of the gums without involvement of the supporting structures, while dental caries refer to tooth decay or cavities in the enamel. Dental abscess is a localized collection of pus caused by a bacterial infection.
