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 home care nurse is providing teaching for a 59-year-old patient taking a nonselective beta-blocker. The nurse teaches the patient the importance of notifying the prescribing physician when what occurs related to this medication?
Correct Answer: B
Rationale: Bronchospasm, cough, rhinitis, and bronchial obstruction are related to loss of bronchodilation of the respiratory tract and vasodilation of mucous membrane vessels so a sudden onset of a cough or difficulty breathing should be immediately reported to the health care provider. Other options may need to be reported but not in relation to the nonselective beta-blocking medication. The nurse should educate the patient about potential adverse effects and the importance of timely reporting.
Question 3 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 4 of 5
Gold salt toxicity can be reversed using which medication?
Correct Answer: B
Rationale: Dimercaprol is a chelating agent used to treat heavy metal toxicity, including gold salt toxicity. It binds to the gold ions, forming a complex that can be excreted from the body. Acetaminophen, calcium salts, and hydroxocobalamin are not used for this purpose. Prompt administration of dimercaprol is essential to prevent severe complications of gold salt toxicity.
Question 5 of 5
A female client who has a history of seizures went to a healthcare facility to ask the nurse regarding the use of birth control pills while on phenytoin therapy. The nurse correctly states to the client that:
Correct Answer: A
Rationale: Phenytoin induces liver enzymes that increase the metabolism of oral contraceptives, reducing their effectiveness. This increases the risk of unintended pregnancy. Pregnancy is not prohibited, but effective contraception is essential. Discontinuing phenytoin is not recommended without medical advice. Therefore, the nurse should inform the client about the decreased effectiveness of birth control pills.
