Take the drug on an empty stomach.

Take the drug along with a meal.

Take the drug along with milk or fruit juice.

Take the drug immediately after meals.

Answer and Explanation

The Correct Answer is A

A. Take the drug on an empty stomach is correct because tetracycline should be taken without food for optimal absorption, ideally 1 hour before or 2 hours after meals.

B. Take the drug along with a meal is incorrect as it can reduce the absorption of tetracycline.

C. Take the drug along with milk or fruit juice is incorrect because calcium and magnesium can bind to tetracycline, decreasing its effectiveness.

D. Take the drug immediately after meals is also incorrect as food can hinder absorption, making this timing ineffective for treatment.

Correct Answer is A

Explanation

A. Spontaneous bleeding after taking an anticoagulant is a secondary action that occurs due to the anticoagulant's effect on blood clotting, which is an undesired effect when it leads to excessive bleeding.

B. Dizziness after starting an antihypertensive is a common secondary action related to the lowering of blood pressure, which can lead to hypotension and resultant dizziness.

C. Drowsiness after taking an antihistamine is a well-known secondary action, especially with first-generation antihistamines, which can cause sedation as a side effect.

D. Diarrhea after taking an antibiotic is a secondary action that can occur due to disruption of the normal gut flora, leading to gastrointestinal upset. All these examples illustrate secondary effects of medications.

A. A 47-year-old female with hypertension B. A 52-year-old male with adult-onset diabetes C. A 17-year-old female with symptoms of an upper respiratory infection D. A 62-year-old male with gout

Correct Answer is A

Explanation

A. Phenylephrine is a decongestant that can raise blood pressure, making it contraindicated for individuals with hypertension. Advising a patient with hypertension to avoid phenylephrine is essential to prevent potential cardiovascular complications.

B. While patients with diabetes should be cautious about certain medications, phenylephrine is not specifically contraindicated in this condition.

C. A 17-year-old female with an upper respiratory infection typically does not have contraindications for phenylephrine unless there are underlying conditions not mentioned.

D. Gout does not have a direct contraindication for phenylephrine use, so the patient may not need to avoid it unless other health issues are present.
