Which of the following dental conditions is characterized by the involuntary grinding or clenching of teeth, often leading to tooth wear, muscle pain, and temporomandibular joint dysfunction?
- A. Dental caries
- B. Attrition
- C. Bruxism
- D. Periodontitis
Correct Answer: C
Rationale: Bruxism is the dental condition characterized by the involuntary grinding or clenching of teeth, often occurring during sleep. This habitual behavior can lead to tooth wear, muscle pain, headaches, and temporomandibular joint dysfunction. Dental caries (choice A) refers to tooth decay, while attrition (choice B) specifically refers to the wearing down of teeth due to forces like chewing. Periodontitis (choice D) is a condition involving inflammation and infection of the gums and supporting structures of the teeth. Among the choices provided, bruxism is the most fitting description for the condition characterized by tooth grinding and clenching.

A patient presents with sudden-onset severe headache, altered mental status, and focal neurological deficits. Imaging reveals a hemorrhagic lesion within the subarachnoid space. Which of the following neurological conditions is most likely responsible for these symptoms?
- A. Ischemic stroke
- B. Subdural hematoma
- C. Intracerebral hemorrhage
- D. Subarachnoid hemorrhage
Correct Answer: D
Rationale: A subarachnoid hemorrhage is characterized by bleeding within the subarachnoid space, the area between the arachnoid mater and the pia mater surrounding the brain. Patients typically present with a sudden-onset severe headache, altered mental status, and focal neurological deficits due to the mass effect of the blood in the subarachnoid space. Imaging, such as a CT scan, can confirm the presence of the hemorrhagic lesion. Ischemic stroke results from a blockage in the blood vessels supplying the brain, leading to tissue infarction and neurological deficits. Subdural hematoma is a collection of blood between the dura mater and the arachnoid mater, commonly seen following head trauma. Intracerebral hemorrhage involves bleeding within the brain tissue itself, often leading to focal neurological deficits.
A patient presents with delayed puberty, short stature, and a childlike appearance. Laboratory tests reveal low levels of growth hormone (GH) and insulin-like growth factor 1 (IGF-1). Which endocrine disorder is most likely responsible for these symptoms?
- A. Hyperthyroidism
- B. Hypothyroidism
- C. Diabetes mellitus
- D. Growth hormone deficiency
Correct Answer: D
Rationale: The patient mentioned in the scenario presents with delayed puberty, short stature, and a childlike appearance. These symptoms are indicative of growth hormone deficiency (GHD). GHD is a condition where the pituitary gland does not produce enough growth hormone, which is crucial for normal growth and development.
A primigravida at 40 weeks gestation is in active labor. The nurse notes late decelerations on the fetal monitor tracing. What action should the nurse take first?
- A. Administer oxygen to the mother.
- B. Change the mother's position.
- C. Prepare for immediate delivery.
- D. Discontinue oxytocin infusion.
Correct Answer: D
Rationale: Late decelerations on the fetal monitor tracing indicate a potential uteroplacental insufficiency, which could be caused by decreased oxygen supply to the fetus. One common cause of late decelerations is uterine hyperstimulation due to excessive use of oxytocin. By discontinuing the oxytocin infusion, the nurse can help alleviate the stress on the fetus and decrease the likelihood of further late decelerations. This action should be prioritized before other interventions such as changing the mother's position or administering oxygen. Immediate delivery may be necessary if the fetus continues to show signs of distress despite discontinuing the oxytocin infusion.
Which of the following is the PRIMARY goal of collaboration
- A. Less numbebr of people is needed
- B. Camaraderie
- C. ACOMPLISH GOALS
- D. Work is faster
Correct Answer: C
Rationale: The primary goal of collaboration is to accomplish shared goals and objectives. When individuals work together towards a common purpose, they can combine their different skills, perspectives, and resources to achieve outcomes that could not be accomplished by working alone. Collaborating enables team members to leverage each other's strengths and expertise, leading to more innovative and effective solutions. While camaraderie and efficiency are important aspects of collaboration, the ultimate aim is to successfully achieve the desired goals.
The ER nurse clarifies the doctor's prescription on the dose of the pain medication based on the pain scale assessment and patient's age. which ethical principle is applied?
- A. Fidelity
- B. Truthfulness
- C. Justice
- D. Non-maleficence
Correct Answer: D
Rationale: Non-maleficence is the ethical principle that emphasizes the obligation to avoid causing harm to patients. In this scenario, the ER nurse clarifies the doctor's prescription to ensure the correct dosage of the pain medication based on the pain scale assessment and the patient's age. By doing so, the nurse is ensuring that the medication is safe and effective for the patient, thus adhering to the principle of non-maleficence. This action demonstrates the nurse's commitment to preventing harm and promoting the well-being of the patient through proper medication management.
