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.

Which of the following BEST describes the PRIMARY goal of CO-PAR?
- A. Enhances the skills of the nurse in research
- B. Makes the community empowered and self -reliant
- C. Increases funding of the community programs
- D. Helps clean-up and beautify the community
Correct Answer: B
Rationale: The PRIMARY goal of CO-PAR (Community-based Participatory Action Research) is to make the community empowered and self-reliant. CO-PAR emphasizes collaboration between researchers and the community members to address issues that directly affect the community. This approach prioritizes community empowerment, leading to sustainable solutions and positive changes within the community. The goal is not just about enhancing individual skills, increasing funding, or beautifying the community, but rather about fostering community ownership and self-reliance in problem-solving and decision-making processes.
A patient is prescribed a calcium channel blocker for the management of hypertension. Which adverse effect should the nurse monitor closely in the patient?
- A. Hypoglycemia
- B. Peripheral edema
- C. Hypokalemia
- D. Tachycardia
Correct Answer: D
Rationale: Calcium channel blockers are often prescribed for the management of hypertension because they can help relax blood vessels and slow the heart rate, thus reducing blood pressure. One of the major adverse effects associated with calcium channel blockers is bradycardia (slow heart rate) or even more rarely, tachycardia (fast heart rate). Therefore, in a patient prescribed a calcium channel blocker for hypertension, the nurse should closely monitor for any signs and symptoms of tachycardia as it can be a serious adverse effect that needs prompt evaluation and intervention to prevent complications.
A patient presents with redness, pain, and photophobia in the left eye. Slit-lamp examination reveals ciliary injection, corneal edema, and a mid-dilated pupil with fixed reaction to light. Which of the following conditions is most likely responsible for this presentation?
- A. Anterior uveitis
- B. Acute angle-closure glaucoma
- C. Endophthalmitis
- D. Corneal abrasion
Correct Answer: A
Rationale: The presentation described in the question is most consistent with anterior uveitis. Anterior uveitis, also known as iritis, is characterized by redness, pain, and photophobia in the affected eye. Slit-lamp examination typically reveals ciliary injection (reddening of the conjunctiva and episclera), corneal edema, and a mid-dilated pupil with a fixed reaction to light (miosis). This occurs due to inflammation within the anterior chamber of the eye involving the iris and ciliary body.
A patient presents with a small, painless, well-defined nodule on the lateral aspect of the neck, just above the clavicle. Fine-needle aspiration cytology reveals clusters of polygonal cells with abundant granular cytoplasm. Which of the following conditions is most likely responsible for this presentation?
- A. Thyroglossal duct cyst
- B. Branchial cleft cyst
- C. Lymphadenopathy
- D. Parathyroid adenoma
Correct Answer: D
Rationale: The presentation described is characteristic of a parathyroid adenoma. Parathyroid adenomas are benign neoplasms that can present as painless, well-defined nodules usually located in the lower pole of the thyroid gland or in close proximity, such as the lateral aspect of the neck above the clavicle. Fine-needle aspiration cytology of a parathyroid adenoma typically reveals polygonal cells with abundant granular cytoplasm, often referred to as chief cells. This is key in differentiating it from other conditions mentioned in the question.
Upon further assessment, you notices that she had any scratches on her right ankle, a resulting infection, and cellulitis. When you asked her about the scratches, the patient states, "Oh, my cat might have been using my leg as a scratiching post again and I did not even feel it." Which diabetic complicatons suspect the patient to have?
- A. Neuropathy
- B. Retinopathy
- C. Macroangiopathy
- D. Nephropathy
Correct Answer: A
Rationale: The patient's lack of sensation in her right leg, allowing her cat to scratch her without her noticing, is indicative of neuropathy. Neuropathy is a common diabetic complication characterized by nerve damage that can result in loss of sensation or altered sensation in different parts of the body, including the extremities. In this case, neuropathy has likely affected the patient's right lower extremity, leading to her inability to feel the cat scratching her leg and resulting in the unnoticed scratches, infection, and subsequent cellulitis.
