The healthcare provider changes a patient’s prescription of warfarin from 5.0 mg to 7.5 mg PO for thromboembolic unit.

The medication available on the unit is 2.5 mg per tablet and the patient already received two tablets.

How many additional tablets should the Practical Nurse (PN) administer to complete the newly prescribed dose? (Enter the numerical value only.

If rounding is required, round to the whole number.)
Answer and Explanation

The Correct Answer is ["1"]

Step 1 is: Calculate the total amount of warfarin required. The healthcare provider has prescribed 7.5 mg of warfarin.

Step 2 is: Subtract the amount of warfarin already administered. The patient has already received 2 tablets, each containing 2.5 mg of warfarin, for a total of 5 mg.

Step 3 is: Calculate the additional amount of warfarin required. The total amount required (7.5 mg) minus the amount already administered (5 mg) equals 2.5 mg.

Step 4 is: Determine the number of additional tablets required. Since each tablet contains 2.5 mg of warfarin, the patient should receive 1 additional tablet.

Correct Answer is B

Explanation

Choice A rationale

Montelukast does not increase the production of mucus in the lungs. In fact, it helps to reduce inflammation and may be used to prevent asthma attacks.

Choice B rationale

Montelukast is a leukotriene modifier that helps to reduce inflammation and prevent asthma attacks and exercise-induced bronchoconstriction. It works by blocking the action of leukotriene D4 in the lungs resulting in decreased inflammation and relaxation of smooth muscle. This prophylactic limitation of the inflammatory response to allergens is a key function of montelukast.

Choice C rationale

Montelukast does not contract the smooth muscles located in the respiratory tract. Instead, it helps to relax the smooth muscles in the lungs, reducing inflammation and making it easier to breathe.

Choice D rationale

Montelukast does not directly repair damaged tissue in the base of the lungs. Its primary function is to prevent and manage symptoms of asthma and allergies by reducing inflammation in the airways.

Explanation

Choice A rationale

Mouth dryness is not a typical therapeutic result of minoxidil. It’s not listed as a common side effect either.

Choice B rationale

Dizziness is a known side effect of minoxidil. It can occur when the medication causes a drop in blood pressure, leading to lightheadedness or dizziness.

Choice C rationale

An elevated blood glucose level is not related to the administration of minoxidil. It could be an unrelated finding, possibly indicating another condition like diabetes.

Choice D rationale

Pain rated at 1/10 is not directly related to the therapeutic effect or side effects of minoxidil. It could be an unrelated finding.
