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.

When there is respiratory depression resulting from drug overdose, the nurse have to watch for which of the following?
- A. Hyperventilation
- B. Biot's respiration
- C. Tachypnea
- D. Bradypnea Situation
Correct Answer: D
Rationale: Respiratory depression resulting from drug overdose typically leads to a decrease in the respiratory rate, known as bradypnea. This is characterized by abnormally slow breathing, which can be dangerous as it may lead to decreased oxygen levels in the blood. Bradypnea indicates a slowing down of the respiratory drive, in contrast to hyperventilation, biot's respiration, or tachypnea. It is crucial for the nurse to monitor a patient experiencing respiratory depression for signs of bradypnea and intervene promptly to prevent further complications.
Which of the following are essential components of informed consent? I. explanation of the procedure and alternatives to the procedure II. discussion of potential risks and benefits of the procedure III. confirmation that the patient understands the risks, benefits, and any alterations
- A. I, III
- B. II, III
- C. I, II
- D. I, II, III
Correct Answer: D
Rationale: All of the components -explanation of the procedure and alternatives to the procedure (I), discussion of potential risks and benefits of the procedure (II), and confirmation that the patient understands the risks, benefits, and any alterations (III) -are essential parts of informed consent. Providing information about the procedure and its alternatives, disclosing potential risks and benefits, and ensuring that the patient comprehends this information are crucial to obtaining valid informed consent prior to any medical procedure.
Nurse Angie added that oral contraceptives also contains progesterone. Which of the following is the action of progesterone in contraception? It inhibits _______.
- A. Testosterone production
- B. GnRH thereby inhibiting FSH and LH productions.
- C. Luteinising Hormone (LH) thereby inhibiting ovulation.
- D. Follicle Stimulating Hormone (FSH) thereby inhibiting maturation of ovum.
Correct Answer: C
Rationale: Progesterone in oral contraceptives works primarily by inhibiting ovulation. It suppresses the secretion of luteinizing hormone (LH) from the pituitary gland, which is essential for triggering the release of an egg (ovulation) from the ovary. By blocking ovulation, progesterone helps prevent pregnancy by making it less likely for a mature egg to be available for fertilization. This mechanism of action is a key factor in the effectiveness of progesterone-containing contraceptives in preventing pregnancy.
Upon data collection he had been failing three times in his math class and Korino was known for substance dependent for three years. What is the MOST APPROPRIATE nursing diagnosis for him?
- A. Alteration in perception.
- B. Ineffective individual coping.
- C. Alteration in social interaction.
- D. Impaired judgment.
Correct Answer: B
Rationale: The most appropriate nursing diagnosis for the individual described is "Ineffective individual coping." This is because the individual has been facing challenges in both academic (failing math class) and personal (substance dependence) aspects of his life. The repeated failures in his math class and the substance dependence for three years indicate that he might be struggling to cope with stressors and challenges in his life effectively. By identifying this nursing diagnosis, the nurse can focus on helping the individual develop effective coping strategies to manage and overcome these difficulties.
A patient with chronic obstructive pulmonary disease (COPD) is prescribed albuterol (salbutamol) inhaler as a rescue medication. Which of the following best describes the pharmacological action of albuterol?
- A. Anticholinergic
- B. Beta-adrenergic agonist
- C. Corticosteroid
- D. Methylxanthine
Correct Answer: B
Rationale: Albuterol, also known as salbutamol, is a beta-adrenergic agonist medication commonly used for the treatment of conditions such as asthma and COPD. As a beta-adrenergic agonist, albuterol binds to beta-2 adrenergic receptors in the lungs, causing bronchodilation, which helps to relieve bronchospasms and improve airflow to the lungs. This action leads to the relaxation of smooth muscle in the airways, thus making breathing easier for patients with COPD or asthma. Anticholinergics, corticosteroids, and methylxanthines have different mechanisms of action and are not directly related to the pharmacological action of albuterol in COPD treatment.
