Correct Answer: A

Rationale: The correct answer is A: Administer epinephrine. Epinephrine is the first-line treatment for anaphylaxis, a severe allergic reaction. It works by constricting blood vessels, increasing heart rate, and opening airways, which can reverse the life-threatening effects of an allergic reaction. Antihistamines (B) may help with mild symptoms but are not sufficient for severe reactions. Corticosteroids (C) are used to reduce inflammation but work too slowly for immediate relief. Beta-blockers (D) can worsen allergic reactions by blocking the effects of epinephrine.

Rationale: The correct answer is D because stopping medication once blood pressure returns to normal can lead to a relapse of hypertension. Step 1: Educate the patient that hypertension is a chronic condition requiring long-term management. Step 2: Explain the importance of continuing medication even when blood pressure is controlled. Step 3: Emphasize the risks of stopping medication abruptly. Other choices are incorrect because they promote positive behaviors for hypertension management: A: Monitoring blood pressure is essential. B: Taking medication consistently is crucial. C: Avoiding high-sodium foods helps control blood pressure.

Correct Answer: D

Rationale: The correct answer is D: Huntington's chorea. Huntington's chorea is a genetic disorder characterized by involuntary, writhing, and twisting movements of the face and limbs, known as chorea. This is due to degeneration of certain brain cells. Epilepsy (A) involves seizures, not specific movements. Parkinson's (B) is characterized by tremors and rigidity, not chorea. Multiple sclerosis (C) affects the central nervous system, causing a variety of symptoms, but not typically chorea.

Correct Answer: B

Rationale: The correct answer is B because critical thinking involves anticipating potential issues to provide proactive care. By predicting potential problems, nurses can prevent complications and tailor interventions accordingly. This step is essential in the nursing process to ensure comprehensive and effective care. Continuing to reassess (A) is important but not the primary focus of a nursing diagnosis. Checking the appropriateness of goals (C) is crucial but comes after identifying the problem and predicting potential issues. Modifying the diagnosis if necessary (D) is a part of critical thinking but not the immediate next step after identifying the actual problem.

Correct Answer: D

Rationale: The correct answer is D because palliative care aims to improve the quality of life for patients with serious illnesses like cancer. Severe pain and nausea (A) are common symptoms that palliative care helps manage. Uncontrolled symptoms despite treatment (B) indicate the need for specialized palliative care interventions. Psychosocial support needs (C) are also addressed in palliative care to address emotional and social aspects of the patient's well-being. Therefore, all of the above (D) are indicative of the need for palliative care as it focuses on holistic symptom management and support for the patient.
