Which is the most common symptom of lung cancer?
Fatigue
Hoarseness
Anorexia
Persistent cough
The Correct Answer is D
A. Fatigue: While fatigue can occur in lung cancer patients, it is not the most common symptom. Fatigue is more of a generalized symptom that can be seen in many diseases, not specific to lung cancer.
B. Hoarseness: Hoarseness can be a symptom of lung cancer, particularly if a tumor is affecting the laryngeal nerves. However, it is less common than a persistent cough and is not usually the initial symptom.
C. Anorexia: Anorexia (loss of appetite) can occur in patients with advanced cancer, including lung cancer, but it is not the most common presenting symptom. Weight loss due to anorexia is more common in later stages.
D. Persistent cough: This is the correct answer. A persistent cough is the most common symptom of lung cancer, especially in the early stages. The cough may be dry or productive and is often overlooked or mistaken for a chronic respiratory condition. It is frequently one of the first signs that leads to further investigation and diagnosis.

Correct Answer is C
Explanation
A. Furosemide is a diuretic that is used to reduce fluid overload and manage conditions like heart failure or kidney disease. It is not indicated in anaphylaxis.
B. Methylprednisolone is a corticosteroid used for its anti-inflammatory properties and can be used in anaphylaxis to reduce inflammation and prevent delayed reactions. However, it is not the first-line treatment in acute anaphylactic shock.
C. Epinephrine is the first-line treatment for anaphylactic shock. It works by rapidly reversing the effects of anaphylaxis, such as bronchoconstriction, vasodilation, and edema, by stimulating alpha and beta receptors. Epinephrine should be administered as soon as anaphylaxis is suspected to stabilize the patient’s condition.
D. Dobutamine is a medication used to manage shock by increasing cardiac output, but it is not used in the management of anaphylactic shock. The priority is epinephrine to reverse the anaphylactic response.
Correct Answer is D
Explanation
A. Insulin detemir is a long-acting basal insulin used for maintenance therapy, not for the rapid reduction of blood glucose levels in acute conditions like diabetic ketoacidosis (DKA).
B. NPH insulin is an intermediate-acting insulin used for long-term blood glucose control, but it is not appropriate for immediate treatment of DKA.
C. Insulin glargine is also a long-acting insulin that works over a prolonged period, making it unsuitable for emergency situations like DKA.
D. Regular insulin is the preferred choice for treating diabetic ketoacidosis. It is a short-acting insulin that can rapidly reduce blood glucose levels and is used intravenously for immediate intervention in DKA.
