Question 1 of 5
Which factors affect the gastrointestinal absorption of medicines? (Select all that apply.) Select 4 options.
Correct Answer: A,C,D,E
Rationale: The factors that affect gastrointestinal absorption of medicines include:
A) Blood flow of the mucous lining of the stomach and intestines - Increased blood flow enhances absorption.
C) Enzyme activity - Enzymes can either enhance or inhibit absorption.
D) Gastric pH - pH affects drug solubility and absorption. E) Gastric emptying time - Faster emptying can reduce absorption. These factors directly influence the rate and extent of drug absorption in the gastrointestinal tract. Blood flow affects the transport of drugs, enzymes play a role in drug metabolism and availability, gastric pH influences drug dissolution, and gastric emptying time affects drug exposure to absorption sites. Other choices (B, F, G) are not directly related to gastrointestinal absorption of medicines and are therefore incorrect.
Question 2 of 5
Which type of nursing action occurs when the nurse administers a medication to a patient?
Correct Answer: A
Rationale: The correct answer is A: Dependent. Administering medication is considered a dependent nursing action because it requires a healthcare provider's order or prescription. Nurses must follow the specific instructions provided by a physician or other authorized prescriber when administering medications to patients. This action is not within the independent scope of nursing practice, as nurses cannot initiate medication administration without a valid order. Interdependent and collaborative actions involve working with other healthcare professionals, but do not directly relate to medication administration. Independent actions refer to nursing interventions that nurses can initiate without needing an order.
Question 3 of 5
The nurse is preparing to administer morning medications. Which action(s) does the nurse implement to identify the patient before administering medications? (Select all that apply)
Correct Answer: A
Rationale: The correct answer is A: Checks the patient's identification band. This action is crucial as it directly verifies the patient's identity through a reliable method. The identification band typically includes the patient's name, date of birth, and other essential information, ensuring accurate medication administration. Asking another nurse (
B) may introduce potential errors. Checking the name on the foot of the bed (
C) is not a reliable method as it can be outdated or incorrect. Asking the roommate (
D) is not appropriate as they may not have accurate information. It's essential to rely on the patient's identification band for accurate identification.
Question 4 of 5
Which action should be implemented next when a patient states they are allergic to the medication the nurse is ready to administer?
Correct Answer: C
Rationale: Rationale for
Choice C: Withholding the medication and notifying the prescriber is the correct action. This ensures patient safety by preventing harm from potential allergic reactions. The prescriber needs to be informed promptly to reassess the medication order and provide an alternative, if necessary. This approach follows the principle of patient advocacy and prioritizes patient well-being.
Summary of Other
Choices:
A: Giving the medication despite the patient's allergy statement is unsafe and disregards patient's concerns.
B: Checking the drug insert alone may not provide immediate guidance on how to proceed with the administration.
D: Giving the medication and monitoring for adverse effects without addressing the allergy issue can lead to serious consequences.
Question 5 of 5
A nurse is preparing to administer amoxicillin 500 mg PO. Available is amoxicillin 250 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: The correct answer is A: 2 tablets.
To achieve a total dose of 500 mg, the nurse needs to administer 2 tablets of 250 mg each (250 mg x 2 = 500 mg). This ensures the patient receives the prescribed dose accurately.
Choices B to G are incorrect as they do not align with the required dosage calculation.
