Nokea
A patient presents with a painless, slowly enlarging mass in the right neck, just above the clavicle. Fine-needle aspiration cytology reveals clusters of polygonal cells with clear cytoplasm and centrally located nuclei. Which of the following conditions is most likely responsible for this presentation?
- A. Parathyroid adenoma
- B. Thyroglossal duct cyst
- C. Lymphadenopathy
- D. Thyroid carcinoma
Correct Answer: A
Rationale: The described presentation of a painless, slowly enlarging mass in the right neck just above the clavicle, along with the cytology findings of clusters of polygonal cells with clear cytoplasm and centrally located nuclei, is classic for parathyroid adenoma. Parathyroid adenomas are benign tumors arising from one of the parathyroid glands, which are typically located in the neck region close to the thyroid gland. The clear cytoplasm and centrally located nuclei of the cells are characteristic histological features of parathyroid adenomas. This condition can often lead to hyperparathyroidism, characterized by increased levels of parathyroid hormone (PTH) and hypercalcemia. Treatment involves surgical removal of the adenoma.

A patient is prescribed a proton pump inhibitor (PPI) for the treatment of peptic ulcer disease. Which adverse effect should the nurse monitor closely in the patient?
- A. Constipation
- B. Hypokalemia
- C. Diarrhea
- D. Clostridium difficile infection
Correct Answer: B
Rationale: Proton pump inhibitors (PPIs) are commonly prescribed for conditions involving excessive stomach acid production, such as peptic ulcer disease. One of the potential adverse effects of PPIs, such as omeprazole or pantoprazole, is the risk of hypokalemia. Hypokalemia is a condition characterized by low levels of potassium in the bloodstream. Prolonged use of PPIs can inhibit the absorption of potassium in the intestines, leading to a decrease in potassium levels in the body. Hypokalemia can present with symptoms such as muscle weakness, fatigue, irregular heartbeat, and in severe cases, it can result in life-threatening complications like cardiac arrhythmias. Therefore, it is essential for the nurse to closely monitor the patient for signs and symptoms of hypokalemia while on PPI therapy, especially if the patient is at risk for developing electrolyte imbalances.
A patient presents with a sudden onset of severe vertigo, nausea, vomiting, and nystagmus. The patient reports a recent upper respiratory tract infection. Which of the following conditions is most likely responsible for this presentation?
- A. Vestibular neuritis
- B. Benign paroxysmal positional vertigo (BPPV)
- C. Ménière's disease
- D. Acoustic neuroma
Correct Answer: A
Rationale: The patient's sudden onset of severe vertigo, nausea, vomiting, and nystagmus following a recent upper respiratory tract infection is consistent with vestibular neuritis. Vestibular neuritis is characterized by acute onset vertigo, often severe, which is typically associated with nausea, vomiting, and nystagmus. The condition is thought to be caused by inflammation of the vestibular nerve, often viral in nature, which can occur following an upper respiratory tract infection. This inflammation leads to dysfunction of the vestibular system in the inner ear, resulting in the symptoms described. Benign paroxysmal positional vertigo (BPPV), characterized by brief episodes of vertigo triggered by specific head movements, is less likely in this case given the sudden onset of symptoms not triggered by head movements. Meniere's disease is characterized by recurrent episodes of vertigo accompanied by hearing loss, tinnitus, and a feeling of fullness
A patient presents with grouped vesicles on an erythematous base, affecting the lips and perioral region. The patient reports a history of similar episodes triggered by sunlight exposure and stress. Which of the following conditions is most likely responsible for this presentation?
- A. Herpes simplex labialis (cold sores)
- B. Perioral dermatitis
- C. Angular cheilitis
- D. Allergic contact dermatitis
Correct Answer: A
Rationale: The patient's presentation with grouped vesicles on an erythematous base affecting the lips and perioral region, triggered by sunlight exposure and stress, is classic for herpes simplex labialis, commonly known as cold sores. Herpes simplex virus type 1 (HSV-1) is responsible for cold sores and is highly contagious. Recurrent episodes can be triggered by factors like UV exposure, stress, illness, and hormonal changes. Symptoms typically start with tingling or burning sensations before progressing to grouped vesicles that rupture, forming crusts. Treatment may involve antiviral medications to reduce the severity and duration of symptoms. Perioral dermatitis typically presents with papules and pustules around the mouth, while angular cheilitis involves fissures and inflammation at the corners of the mouth. Allergic contact dermatitis would present with erythema, pruritus, and possibly vesicles in
As a nurse you are guided that pain is usually described BEST as a phenomenon which is a ________.
- A. Neurologic activation nociceptors
- B. Subjective unpleasant experience
- C. Adaptive mechanism to a stimulus
- D. Creation of one's imagination
Correct Answer: B
Rationale: Pain is best described as a subjective unpleasant experience because it is unique to each individual and is influenced by a variety of factors including emotional, psychological, and cultural elements. Pain cannot be objectively measured or quantified, and therefore it is considered a subjective experience that is reported by the person experiencing it. This is why pain is often assessed using self-report scales and tools to capture the individual's perception of their pain intensity and quality.
