A patient presents with palpitations, dizziness, and syncope. An electrocardiogram (ECG) shows ventricular tachycardia. Which cardiovascular disorder is most likely responsible for these symptoms?

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,

Correct Answer: A

Rationale: The correct answer is A because a viral illness few weeks before can trigger Guillain-Barre Syndrome (GBS) due to the body's immune response attacking the peripheral nerves. Encephalitis (B), severe bacterial infection (C), and meningitis (D) are not directly linked to GBS pathophysiology. Viral infections are known to precede GBS development, making choice A the most appropriate option.

Correct Answer: A

Rationale: Rationale: A is the correct answer as it demonstrates therapeutic communication by encouraging Annie to express her feelings and fears. It shows empathy and understanding, allowing Annie to elaborate on her concerns. B is incorrect as it dismisses Annie's fears and implies blame on her parenting. C is incorrect as it focuses on the behavior of the children rather than addressing Annie's emotions. D is incorrect as it places the responsibility on the children to make Annie feel comfortable, rather than addressing her concerns directly.

Correct Answer: A

Rationale: The correct answer is A: Anterior uveitis. This condition presents with redness, pain, and photophobia due to inflammation of the uveal tract. Ciliary injection, corneal edema, and mid-dilated pupil with fixed reaction to light are classic signs of anterior uveitis. The other choices can be ruled out based on specific findings: B: Acute angle-closure glaucoma would present with a high intraocular pressure, not fixed dilated pupil. C: Endophthalmitis typically presents with severe pain, hypopyon, and vitreous inflammation. D: Corneal abrasion would not cause ciliary injection or fixed dilated pupil.

Correct Answer: B

Rationale: The correct answer is B because actively listening, acknowledging the patient's concerns, and working towards rebuilding trust through transparency and reliability are essential steps in addressing distrust. By validating the patient's experiences and actively involving them in the process, the nurse can foster a supportive and trusting relationship. Choice A is incorrect because dismissing the patient's concerns can further damage trust and undermine the patient's feelings. Choice C is incorrect as ignoring the distrust can lead to a breakdown in communication and trust. Choice D is incorrect because telling the patient to trust the healthcare system without addressing their concerns is dismissive and unhelpful.

Correct Answer: D

Rationale: The correct answer is D because confirming the insertion site and direction using imaging guidance ensures precise placement of the chest tube, minimizing the risk of complications. Imaging guidance allows the nurse to visualize the exact location of the pneumothorax and guide the tube insertion accurately. A: Positioning the patient in a semi-Fowler's position with arms elevated may be beneficial for comfort but does not directly ensure proper chest tube placement. B: Marking the insertion site with a pen may help as a reference point but does not guarantee accurate placement. C: Administering analgesia is important for the patient's comfort but does not impact the placement of the chest tube. In summary, choice D is the most critical step to ensure the chest tube is correctly placed and effectively treats the pneumothorax.

Correct Answer: B

Rationale: The correct answer is B: How the nurse will behave. Standards of nursing care refer to the expected behaviors and practices that nurses should adhere to in providing quality care to patients. This encompasses ethical principles, professional conduct, and best practices in nursing. It is essential for nurses to follow these standards to ensure patient safety and quality outcomes. Explanation: - A: What protects the nurse. This choice is incorrect because standards of nursing care primarily focus on patient care and outcomes, rather than protecting the nurse. - C: How much work is done. This choice is incorrect as it does not directly relate to the behaviors and practices expected of nurses in providing quality care. - D: Ask the local officials. This choice is unrelated to the concept of standards of nursing care and is not relevant to the question.

Correct Answer: C

Rationale: The correct answer is C: Cryptosporidium parvum. This parasite is the most likely cause of the infection due to its presentation with watery diarrhea, abdominal cramps, and nausea after consuming contaminated water. Laboratory tests revealing oocysts in the stool sample further support this diagnosis as Cryptosporidium parvum is known to produce oocysts in the stool. Giardia lamblia (choice A) presents with similar symptoms but does not typically produce oocysts. Entamoeba histolytica (choice B) is more associated with bloody diarrhea and liver abscesses. Cyclospora cayetanensis (choice D) is also associated with watery diarrhea but is less common in this scenario. Thus, based on the symptoms and laboratory findings, Cryptosporidium parvum is the most likely culprit.

Correct Answer: C

Rationale: The correct answer is C because independence for the elderly means they have the freedom to make choices and decisions about their own lives. This empowers them to live according to their preferences and values. Choice A is incorrect because it doesn't consider individual circumstances; choice B is important but doesn't capture the essence of independence; choice D is too broad and doesn't specifically address the concept of personal autonomy and agency for the elderly.
