Upon arriving at a scene where a patient has been involved in a minor car accident, she reports feeling faint and states that she has a history of diabetes. Given this information, what is the primary concern that the patient is expressing?

Correct Answer: A

Rationale: The correct answer is A: Her blood sugar levels are likely unstable. Given the patient's history of diabetes and feeling faint after a minor car accident, the primary concern is hypoglycemia, which can occur due to stress or delayed food intake. Symptoms may include feeling faint, weakness, and confusion. It is important to address this immediately as untreated hypoglycemia can lead to serious complications. Choice B is incorrect as a headache is not typically a primary concern for a diabetic patient feeling faint. Choice C is incorrect as hypertension is not directly related to the symptoms described. Choice D is incorrect as nausea is not a typical symptom of hypoglycemia in this context. It is crucial to focus on the patient's diabetic history and potential hypoglycemia in this scenario.

Correct Answer: D

Rationale: The correct answer is D: Trachea position. This is the key observation to prioritize during the neck examination because in a patient presenting with noticeable swelling in the neck area and difficulty breathing, a deviated trachea indicates a potential emergency situation such as a mediastinal mass or tension pneumothorax. Assessing the trachea position helps in identifying any life-threatening conditions that may be causing the respiratory distress. A: Thyroid fullness may indicate thyroid issues, but in this case, the focus should be on the trachea position due to the acute presentation of difficulty breathing. B: Pulsation may be relevant in other contexts but is not the priority when assessing a patient with difficulty breathing and neck swelling. C: Respiratory difficulty is already mentioned in the patient presentation, and the focus should be on identifying the cause of this difficulty, which is best assessed by evaluating the trachea position.

Correct Answer: C

Rationale: The correct diagnosis is C: Parkinson's disease. The symptoms of confusion, tremors, and bradykinesia are classic features of Parkinson's disease, a neurodegenerative disorder affecting movement. The typical onset age aligns with the patient's age. Alzheimer's disease (A) primarily affects memory and cognition, Huntington's disease (B) presents with involuntary movements and cognitive decline, and Multiple sclerosis (D) involves the immune system attacking the central nervous system causing a variety of symptoms. Parkinson's is the most appropriate choice based on the symptom presentation and age of the patient.

Correct Answer: A

Rationale: The correct answer is A: Lisinopril. Lisinopril is an ACE inhibitor commonly prescribed for patients with hypertension and chronic kidney disease. It helps to reduce blood pressure and protect the kidneys by dilating blood vessels and improving blood flow. Furosemide (B) is a diuretic used to treat fluid retention but not specifically indicated for chronic kidney disease. Metoprolol (C) is a beta-blocker primarily used for heart conditions. Spironolactone (D) is a potassium-sparing diuretic and is not the first-line treatment for hypertension in patients with chronic kidney disease.

Correct Answer: B

Rationale: The correct answer is B: Dry mouth and skin. Dehydration in older adults can lead to dry mouth and skin due to the lack of proper hydration. This is an early sign as the body starts to lose water. Weight gain (A) is not indicative of dehydration, as it typically occurs with fluid retention. Decreased urine output (C) is a later sign of dehydration, as the body conserves water. Increased thirst (D) is a response to dehydration but not an early sign. Therefore, dry mouth and skin are the most relevant early indicators of dehydration in older adults.
