Question 1 of 5
When taking Nitroglycerine (transdermal), you should have how many hours nitrate free each day?
Correct Answer: D
Rationale: When using Nitroglycerine transdermal patches, it is recommended to have a nitrate-free period of at least 10-12 hours each day to prevent the development of tolerance to the medication. Continuous exposure to nitrates can lead to a decrease in efficacy over time. By having a nitrate-free interval each day, the body has a chance to "reset" and maintain the effectiveness of the medication for angina control. It is crucial to follow this dosing schedule as directed by a healthcare provider to ensure optimal benefits and reduce the risk of tolerance.
Question 2 of 5
The nurse has a patient demonstrate self-administration of eyedrops. Place the steps in the order in which the patient will perform them.
Correct Answer: B
Rationale: The correct order for self-administering eyedrops is: 1. Wash hands (g). 2. Remove the cap (d). 3. Gently shake the bottle to evenly distribute the drug (b). 4. Tilt the head backward and look upward (e). 5. Pull the lower lid away from the eye so that a pouch is formed (a). 6. Place the dropper just above the pouch without touching the tip to the eye or finger (f). 7. Gently squeeze one drop of medicine into the pouch (h). 8. Press a finger against the inner corner of the eye for 2 to 3 minutes (c). This sequence ensures proper administration and minimizes the risk of contamination or systemic absorption.
Question 3 of 5
A 40-year-old patient experiencing periods of mania and periods of depression would most likely benefit from which of the following?
Correct Answer: D
Rationale: Carbamazepine, a mood stabilizer, treats bipolar mania/depression-per psychiatry-unlike atomoxetine (ADHD), amitriptyline (depression), or methylphenidate (ADHD). It fits cycles, per evidence.
Question 4 of 5
The pharmacokinetic elimination half-life of the following drugs mirrors their pharmacodynamic duration and intensity of action:
Correct Answer: C
Rationale: Dobutamine's pharmacodynamic effects closely match its short half-life, as it is rapidly metabolized and its action declines quickly.
Question 5 of 5
When administering heparin subcutaneously, the nurse will follow which procedure?
Correct Answer: D
Rationale: When administering heparin subcutaneously, the nurse should use a - to -inch, 25- to 30-gauge needle to inject the medication into the subcutaneous tissue. This needle size is appropriate for delivering the medication effectively and safely in the subcutaneous layer rather than deeper into the muscle. Using the correct needle size helps ensure proper absorption and reduces the risk of complications such as bleeding or bruising at the injection site.
