liver failure

renal failure

respiratory failure

heart failure

Answer and Explanation

The Correct Answer is D

A. Liver failure does not have a direct contraindication with bronchodilators, though careful monitoring is needed.

B. Renal failure is not a direct contraindication for bronchodilator use; however, kidney function can affect drug metabolism and clearance.

C. Respiratory failure may necessitate bronchodilator therapy rather than caution, especially in conditions like COPD or asthma where bronchodilators are crucial for management.

Correct Answer is A

Explanation

A. An INR of 5.0 indicates a significantly increased risk of bleeding, and administering vitamin K is the appropriate antidote for reversing the effects of warfarin. This is a critical intervention to restore coagulation.

B. Increasing the dose of warfarin is inappropriate in this scenario because the INR is already elevated; it would further increase bleeding risk.

C. While heparin can be used for anticoagulation, it is not appropriate to administer it while the INR is dangerously high without reversing the warfarin first.

D. Continuing warfarin is unsafe at this INR level due to the high risk of bleeding; monitoring for symptoms without intervention is not adequate care.

A. "Milk helps the medication absorb more quickly." B. "You should avoid milk and dairy products when taking tetracycline, as they reduce its effectiveness." C. "It is safe to take milk with tetracycline, as long as you increase your water intake." D. "It is fine to drink milk if taken at least 1 hour before or 2 hours after."

Correct Answer is B

Explanation

A. Milk does not enhance the absorption of tetracycline; rather, it contains calcium, which can bind to the antibiotic and reduce its absorption.

B. Avoiding milk and dairy products while taking tetracycline is essential as they reduce the medication's effectiveness by forming insoluble complexes with the drug.

C. Taking milk with tetracycline is not safe due to the risk of decreased absorption; simply increasing water intake does not negate this interaction.

D. While spacing the intake of milk and tetracycline might seem beneficial, it is best to avoid dairy entirely during the treatment to ensure maximum efficacy of the medication.
