ATI RN Pharmacology Proctored Exam 2023 Questions
Question 1 of 5
Diazepam (Valium) is prescribed to a client with alcohol withdrawal. Which of the following statements made by the client indicates an understanding of the treatment regimen?
Correct Answer: C
Rationale: The statement "I'll have my physician lower my dosage once I start to feel okay" indicates an understanding of the treatment regimen because Diazepam is typically used as a short-term treatment for alcohol withdrawal symptoms. Once the client starts to feel okay, it is important to gradually taper off the medication under the guidance of a healthcare provider to prevent withdrawal symptoms. This demonstrates the client's understanding of the appropriate course of treatment and the need for medical supervision throughout the process.
Question 2 of 5
An 18-year-old male is being evaluated for hypogonadism. The nurse would evaluate which physical findings as supporting that tentative diagnosis?
Correct Answer: A
Rationale: Hypogonadism in males, marked by low testosterone, delays secondary sexual characteristics, like facial hair, which remains minimal, soft, and light due to insufficient androgen stimulation of follicles. Absent pubic hair aligns with this, reflecting poor pubertal development from gonadal dysfunction. Decreased subcutaneous fat is less typical-hypogonadism often increases fat due to estrogen dominance from low testosterone. Small testicles directly indicate testicular failure, a hallmark of primary hypogonadism, reducing hormone and sperm output. Minimal facial hair is a visible, assessable sign tied to androgen deficiency, distinguishing it from normal variation, and supports the diagnosis alongside other findings like testicular size, reflecting the condition's impact on masculinization and reproductive maturity.
Question 3 of 5
A woman who wishes to become pregnant is concerned about the drugs she must take in order to treat a serious medical condition. The nurse reviewing the drug list would be most concerned about which kind of drug?
Correct Answer: A
Rationale: Long half-life drugs (e.g., diazepam) linger, risking fetal exposure post-conception, a pharmacokinetic worry for serious conditions. No active metabolites reduce risk. High protein-binding limits free drug, less concern. As-needed use minimizes exposure. Long half-life heightens teratogenic potential, critical in planning.
Question 4 of 5
The client receives diphenhydramine (Benadryl) to control allergic symptoms. Which common symptom does the nurse teach the client to report to the physician?
Correct Answer: D
Rationale: Diphenhydramine's anticholinergic effects include urinary hesitancy , a serious symptom risking retention, needing physician reporting. Sedation is expected. Diarrhea and vomiting aren't typical. D prioritizes significant complications, making it the key symptom.
Question 5 of 5
A patient is receiving heparin therapy as part of the treatment for a pulmonary embolism. The nurse monitors the results of which laboratory test to check the drug™s effectiveness?
Correct Answer: B
Rationale: The nurse monitors the aPTT to check the effectiveness of heparin therapy in preventing and treating blood clots. Heparin acts by inhibiting the clotting cascade, specifically by enhancing the activity of antithrombin III, which inactivates clotting factors such as thrombin and factor Xa. The aPTT measures the intrinsic pathway of the clotting cascade, which is affected by heparin therapy. By monitoring the patient's aPTT levels, the nurse can ensure that the patient is within the therapeutic range for heparin therapy to be effective in preventing further clot formation. Monitoring bleeding times, PT/INR, or vitamin K levels is not typically done to assess heparin therapy effectiveness.
