Nokea
Which of the following is NOT an opioid or NSAID?
- A. Morphine
- B. Ibuprofen
- C. Hydromorpho
- D. Acetaminoph en
Correct Answer: D
Rationale: Acetaminophen is not an opioid or NSAID. It is a pain reliever and fever reducer, but it works in a different way compared to opioids and NSAIDs. Unlike opioids, acetaminophen does not have the same risk of physical dependence or addiction. And unlike NSAIDs, acetaminophen does not have anti-inflammatory properties. It is often used for mild to moderate pain relief and as a fever reducer. Be cautious when taking acetaminophen, as high doses can be harmful to the liver.

What is a side effect of Heparin?
- A. nausea
- B. diarrhea
- C. bleeding
- D. bronchospasms
Correct Answer: C
Rationale: A common side effect of Heparin, which is an anticoagulant medication, is the risk of bleeding. Heparin works by preventing the formation of blood clots, which can lead to a bleeding risk as it inhibits the normal clotting process. Patients taking Heparin should be monitored closely for signs of bleeding, such as easy bruising, prolonged bleeding from minor cuts, or blood in the urine or stools. It is important for healthcare providers to closely monitor patients on Heparin therapy and adjust the dosage as needed to minimize the risk of excessive bleeding.
A patient asks how to apply transdermal nitroglycerin. What is the nurse™s best response?
- A. Always apply the transdermal patch over the area of your chest where your heart is.
- B. Keep the previous patch on for 1 full day so you always have two patches on at a tim
- C.
- D. Apply the patch to hairless areas of the body.
Correct Answer: D
Rationale: Transdermal nitroglycerin patches should be applied to clean, dry, hairless areas of the body to ensure proper absorption of the medication. Hair can interfere with the absorption of the medication through the skin. Commonly recommended areas for application include the chest, upper arm, or abdomen. It is important to rotate application sites to prevent skin irritation and to follow the specific instructions provided by the healthcare provider or pharmacist.
The following are anticoagulants that do not require monitoring of INR:
- A. Rivaroxaban
- B. Apixaban
- C. Dabigatran
- D. All of the above
Correct Answer: D
Rationale: These are direct oral anticoagulants (DOACs), which do not require regular INR monitoring.
An overwhelmed nursing student asks the instructor whether there are any tips that will make learning pharmacology easier. The instructor gives an example of the anticoagulant heparin. The instructor indicates that knowing heparin and comparing other drugs to it will facilitate learning the many anticoagulants. Which approach is the instructor using?
- A. Mechanism of action approach
- B. Generic name approach
- C. Trade name approach
- D. Prototype drug approach
Correct Answer: D
Rationale: The prototype approach uses a representative drug like heparin to learn a class (anticoagulants), comparing others to its traits-mechanism, effects, side effects-simplifying study. Mechanism of action is narrower. Generic or trade names focus on nomenclature, not learning strategy. Prototype leverages a familiar example, a proven method for mastering drug groups.
The nurse administering the phosphodiesterase inhibitor milrinone (Primacor) recognizes that this drug will have a positive inotropic effect. Which result reflects this effect?
- A. Increased heart rate
- B. Increased blood vessel dilation
- C. Increased force of cardiac contractions
- D. Increased conduction of electrical impulses across the heart
Correct Answer: C
Rationale: Milrinone is a phosphodiesterase inhibitor that works by increasing the levels of cyclic adenosine monophosphate (cAMP) within cardiac myocytes. This leads to enhanced calcium influx into the cells, ultimately resulting in increased force of cardiac contractions (positive inotropic effect). This increased contractility helps improve cardiac output without necessarily increasing heart rate or affecting blood vessel dilation.
