ATI Pharmacology Exam Practice Questions
Question 1 of 5
When educating a patient about Regular Insulin, you should include which instruction:
Correct Answer: D
Rationale: When educating a patient about Regular Insulin, you should include the instruction to inject the insulin subcutaneously. Regular insulin is a short-acting insulin that should be injected into the subcutaneous tissue rather than intramuscularly or intravenously. Subcutaneous injection ensures proper absorption and effectiveness of the insulin. It is important to educate the patient on the correct injection technique and site rotation to optimize insulin absorption and minimize the risk of lipodystrophy.
Question 2 of 5
Pregnancy advise is given in what Part of the MIMS:
Correct Answer: A
Rationale: Pregnancy advice is typically provided under the "Preg. Cat." section in the MIMS (Monthly Index of Medical Specialities) guide or database. This section specifically categorizes medications based on their safety profiles during pregnancy, providing healthcare professionals with essential information to make informed decisions regarding drug use in pregnant patients. It includes details on pregnancy categories that classify drugs according to their potential risks during pregnancy, guiding healthcare providers on the appropriateness of prescribing certain medications to pregnant individuals. Therefore, for pregnancy-related advice in the context of medication safety, referring to the "Preg. Cat." section in the MIMS is the most relevant source of information.
Question 3 of 5
A solution for the eyes
Correct Answer: D
Rationale: Collyria refers to eye drops or an eye lotion that is used to treat eye conditions. When the question is asking for a solution for the eyes, collyria is the most appropriate choice among the options given. Effervescent, mucilage, and spirits do not specifically relate to eye treatments. Collodion is a type of liquid adhesive used in medical settings, but it is not primarily intended for eye-related issues. Therefore, collyria is the correct solution for the eyes.
Question 4 of 5
Which of the following most accurately describes the antibacterial mechanism of penicillin:
Correct Answer: B
Rationale: Penicillin is a type of antibiotic that works by inhibiting bacterial cell wall synthesis. Peptidoglycan is a critical component of the bacterial cell wall, providing structural support and preventing the cell from bursting. Penicillin specifically targets the final step in peptidoglycan synthesis, known as cross-linking, by binding to and inhibiting the enzyme transpeptidase. Without proper cross-linking of peptidoglycan, the bacterial cell wall becomes weak and compromised, leading to cell lysis and bacterial death. This mechanism makes penicillin highly effective in combating bacterial infections.
Question 5 of 5
A patient diagnosed with cancer is scheduled to receive vincristine. Which nursing assessment will have the highest priority when providing care for this patient?
Correct Answer: D
Rationale: Vincristine is known to cause peripheral neuropathy, a common and potentially debilitating side effect. The nurse should prioritize assessing for signs of neuropathy, such as tingling, numbness, or weakness in the extremities. Alopecia, while distressing, is not as critical as neuropathy, which can affect the patient's mobility and quality of life. Vincristine does not typically cause significant changes in digoxin or phenytoin levels, making these assessments less relevant. Early detection of neuropathy allows for dose adjustments or supportive interventions to minimize long-term damage.
