ATI Nursing 100 Day Exam 4 Fundamentals Questions
Extract:
Question 1 of 5
The nurse is giving vancomycin to a client and must hold the dose until the results of the trough level are known. This term is associated with the point at which the:
Correct Answer: C
Rationale: The correct answer is C: Blood serum drug concentration is lowest. A trough level is the lowest concentration of a drug in the bloodstream before the next dose is given. Holding the dose until the trough level is known ensures the drug is not given too soon, preventing toxicity and maintaining therapeutic levels.
Choice A is incorrect as it describes the concept of half-life, not trough level.
Choice B is incorrect as toxicity is not specifically related to trough levels.
Choice D is incorrect as it refers to peak concentration, not trough level.
Question 2 of 5
A client is diagnosed with chronic constipation. The nurse is given an order by the physician to administer a glycerin suppository. What abbreviation will be written in the physician's order for the administration route for the suppository?
Correct Answer: D
Rationale: The correct answer is D: PR. "PR" stands for "per rectum," which means the suppository will be administered through the rectum. This route is appropriate for glycerin suppositories as they are designed to stimulate bowel movement by irritating the rectal mucosa. The other choices are incorrect: A: S/P means status post, B: RS is not a standard abbreviation for a suppository route, and C: R is not a recognized abbreviation for the rectal route.
Therefore, PR is the correct abbreviation for the physician's order.
Question 3 of 5
The nurse is caring for a client who is at high risk for development of pressure injury. The client is able to move independently but has been placed on bedrest. The client has experienced two episodes of urinary incontinence. Which intervention(s) should the nurse include in the care plan?
Correct Answer: A,D,E
Rationale: The correct interventions are A, D, and E. A is correct because frequent weight shifting promotes circulation and reduces pressure on skin. D is important to protect the skin from moisture-related damage. E is necessary to prevent pressure injuries by using appropriate support surfaces. B is incorrect as it does not directly address pressure injury prevention. C is incorrect as massaging bony prominences can increase the risk of pressure injuries.
Question 4 of 5
A client has a serum potassium level of 6.3 mEq/L. The nurse recognizes that the highest priority intervention(s) for this client are to:
Correct Answer: C,E
Rationale: The correct answers are C and E. A serum potassium level of 6.3 mEq/L indicates hyperkalemia, which can lead to serious complications like cardiac arrhythmias.
Choice C is correct because assessing the client for muscle weakness and flaccid paralysis helps to monitor for potential cardiac issues.
Choice E is also correct as obtaining a physician's order for cardiac monitoring is crucial to continuously monitor the client's cardiac status.
Choices A, B, and D are incorrect.
Choice A is not a priority as diluting potassium elixir does not address the immediate risk of hyperkalemia.
Choice B is not the highest priority as it does not address the urgent need to monitor for cardiac complications.
Choice D is incorrect as encouraging intake of potassium-rich foods can worsen hyperkalemia.
Question 5 of 5
The nurse knows that which form of medication delivery results in the most predictable onset and most bioavailability to the client?
Correct Answer: A
Rationale: The correct answer is A: Intravenous. Intravenous administration delivers medication directly into the bloodstream, resulting in rapid onset and 100% bioavailability. This route bypasses first-pass metabolism, ensuring the entire dose reaches the systemic circulation. Subcutaneous and transdermal routes have slower onset and lower bioavailability due to absorption limitations. Oral route has variable onset and bioavailability due to factors like gastrointestinal pH and metabolism. Intravenous administration offers the most predictable and efficient drug delivery.
