Nokea
A patient presents with severe sore throat, fever, and enlarged tonsils with exudate. Rapid antigen testing confirms group A beta-hemolytic Streptococcus (GAS) infection. Which of the following medications is the first-line treatment for this condition?
- A. Amoxicillin
- B. Azithromycin
- C. Cephalexin
- D. Clindamycin
Correct Answer: A
Rationale: The correct answer is A: Amoxicillin. Amoxicillin is the first-line treatment for GAS pharyngitis due to its effectiveness against Streptococcus bacteria. It is a penicillin-class antibiotic recommended by guidelines. Azithromycin is an alternative for patients allergic to penicillin. Cephalexin is not the first-line choice for GAS. Clindamycin is reserved for patients allergic to both penicillin and macrolides.

Nurse Pedrito is teaching a client with Parkinson's disease on ways to prevent curvatures of the spine associated with the disease. To prevent spinal flexion, the nurse should tell the client to _________.
- A. Rest in supine position with his head elevated.
- B. Sleep only in dorsal recumbent position.
- C. Periodically lie in prone position without a neck pillow.
- D. Sleep on either side, but keep his back straight.
Correct Answer: C
Rationale: The correct answer is C: Periodically lie in prone position without a neck pillow. This position helps to prevent spinal flexion by promoting extension of the spine and stretching of the hip flexors. Prone positioning also helps maintain alignment of the spine and prevents contractures. Resting in supine position (choice A) with the head elevated does not promote spinal extension. Sleeping only in dorsal recumbent position (choice B) may lead to spinal flexion. Sleeping on either side (choice D) does not specifically address spinal flexion prevention.
Which of the following is an example of a PRIMARY) source in a research study?
- A. A textbook of medical-surgical nursing
- B. A doctoral dissertation that critiques all research in the area of attention deficit disorder
- C. A published commentary on the findings of another study
- D. A journal article about a study that used large, previously unpublished databases generated
Correct Answer: D
Rationale: The correct answer is D because a journal article about a study using large, previously unpublished databases is a primary source as it presents original research findings firsthand. It contributes new knowledge to the field. A textbook (A) compiles existing information, not original research. A doctoral dissertation (B) critiques research but is not a primary source. A published commentary (C) interprets others' findings, making it a secondary source.
A Patients to take regularly Lithium after discharged. The MOST important information to impart to the patient and his family is that the patient should
- A. not eat foods which has high tyramine content like cheese, wine, liver
- B. limit his fluid intake
- C. have a limited intake of sodium
- D. have an adequate intake of sodium
Correct Answer: C
Rationale: The correct answer is C, to have a limited intake of sodium. Lithium can lead to increased sodium levels in the body, potentially causing toxicity. By limiting sodium intake, the patient can maintain a balance and prevent adverse effects. Choice A is incorrect as tyramine content is not directly related to lithium intake. Choice B is incorrect as fluid intake does not have a significant impact on lithium levels. Choice D is incorrect because an adequate intake of sodium can lead to worsening lithium toxicity.
Patient Ximena sought referral to an abort ion clinic from the nurse. She reasons out that her pregnancy a burden to her work and daily routines. What should be the BEST RESPONSE of the nurse?

Choices B, C, and D are incorrect because they do not directly address the patient's reasons for seeking an abortion. Choice B imposes moral and legal judgments, which can be insensitive. Choice C is not relevant to the patient's stated reason. Choice D imposes religious beliefs, which may not align with the patient's own beliefs.
A patient presents with palpitations, dizziness, and syncope. An electrocardiogram (ECG) shows ventricular tachycardia. Which cardiovascular disorder is most likely responsible for these symptoms?
- A. Stable angina
- B. Unstable angina
- C. Atrial fibrillation
- D. Ventricular tachycardia
Correct Answer: D
Rationale: The correct answer is D: Ventricular tachycardia. Ventricular tachycardia is a serious arrhythmia that can lead to palpitations, dizziness, and syncope due to the rapid and abnormal heart rhythm originating in the ventricles. This arrhythmia can be life-threatening if not promptly treated.
A: Stable angina is characterized by chest discomfort or pain due to reduced blood flow to the heart muscle, usually during physical exertion or stress. It does not typically present with palpitations, dizziness, or syncope.
B: Unstable angina is a more severe form of angina where symptoms occur even at rest. While it can lead to serious complications like heart attack, it does not commonly present with palpitations, dizziness, or syncope.
C: Atrial fibrillation is a common arrhythmia originating in the atria, leading to an irregular and often rapid heartbeat. While it can cause palpitations and dizziness,
