Question 1 of 5
Which of the following is described as the fastest route of drug administration?
Correct Answer: A
Rationale: Intravenous (I.V.) administration is described as the fastest route of drug administration because the medication is directly delivered into the bloodstream. This allows for immediate systemic circulation and rapid onset of action, making it the most efficient route for drugs to reach their target organs or tissues. In contrast, other routes such as intramuscular (I.M), oral, rectal, and intradermal have slower absorption rates and may involve additional barriers before reaching the bloodstream, causing a delay in onset of action compared to intravenous administration.
Question 2 of 5
The nurse is caring for a patient who is taking warfarin. The nurse notes the presence of gross hematuria and large areas of bruising on the patient's body. The nurse notifies the health care prescriber and anticipates what medication will be ordered?
Correct Answer: C
Rationale: Gross hematuria and bruising are signs of excessive anticoagulation, likely due to warfarin. Phytonadione (Vitamin K) is the antidote for warfarin toxicity and will be ordered to reverse its effects. Heparin sulfate (
A) and protamine sulfate (
B) are used for heparin reversal, and potassium supplements (
D) are unrelated to warfarin toxicity.
Question 3 of 5
While assessing a patient who is taking a beta blocker for angina, the nurse knows to monitor for which adverse effect?
Correct Answer: C
Rationale: Beta blockers are medications commonly used to treat angina by reducing the heart's workload and oxygen demand. One common side effect of beta blockers is bradycardia, which is a slower than normal heart rate. Since beta blockers work by blocking the effects of adrenaline on the heart, they can slow down the heart rate. It is important for the nurse to monitor the patient for signs and symptoms of bradycardia, such as fatigue, dizziness, and confusion, especially when assessing a patient taking beta blockers for angina.
Question 4 of 5
_______________ is the main glucocorticoid produced by the adrenal glands.
Correct Answer: B
Rationale: Hydrocortisone is the main glucocorticoid produced by the adrenal glands. Glucocorticoids are a class of corticosteroid hormones that are involved in regulating metabolism and immune responses. Hydrocortisone, also known as cortisol, plays a crucial role in the body's response to stress, inflammation, and maintaining blood pressure. It is essential for various physiological functions, including regulating blood sugar levels and suppressing the immune system's inflammatory responses. While other glucocorticoids like dexamethasone and prednisone are commonly used in clinical practice for their anti-inflammatory and immunosuppressive effects, hydrocortisone is the primary glucocorticoid naturally produced by the adrenal glands.
Question 5 of 5
A 22-year-old woman ingests an entire bottle of acetaminophen in an attempted suicide. She unexpectedly feels well; and when her boyfriend discovers what she has done, he takes her to the emergency department. Which of the following drugs should be given in the ER?
Correct Answer: B
Rationale: Acetaminophen overdose needs acetylcysteine , replenishing glutathione to detoxify NAPQI, preventing liver damage. Aspirin , bicarbonate , fomepizole , and penicillamine (E) don't apply. Early administration reverses her silent toxicity.
