Question 1 of 5
A nurse should suspect which disorder when a client is able to move his arm in private but states to others that his arm is paralyzed?
Correct Answer: C
Rationale: Personality disorder: Personality disorders involve enduring patterns of behavior and inner experiences that deviate from the norm, but they do not typically include symptoms like claimed paralysis. Hypochondriasis: Hypochondriasis (now classified as illness anxiety disorder) involves excessive worry about having a serious illness but does not involve actual loss of function. Conversion disorder: Conversion disorder involves neurological symptoms that cannot be explained by medical evaluation. Symptoms can include paralysis, blindness, or other neurological deficits that are inconsistent with medical findings and often arise in response to psychological stress. Cyclothymic disorder: Cyclothymic disorder involves chronic fluctuating moods but does not typically include conversion symptoms like paralysis.
Question 2 of 5
A nurse is assessing the therapeutic International Normalized Ratio (INR) range for a patient receiving Warfarin. Which INR range below is therapeutic?
Correct Answer: A
Rationale: INR 2.0–3.0 is the standard therapeutic range for warfarin in conditions like atrial fibrillation or DVT, balancing clot prevention and bleeding risk. 4.0–5.0 and 3.0–4.9 risk bleeding; 1.0–2.0 is subtherapeutic, risking clots. 2.0–3.0 aligns with clinical guidelines.
Question 3 of 5
A nurse is caring for a client who has a prescription for digoxin 0.25 mg PO daily. The amount available is digoxin 0.125 mg/tablet. How many tablets should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 2
Rationale: Prescribed dose: 0.25 mg; available: 0.125 mg/tablet. Calculation: 0.25 ÷ 0.125 = 2 tablets. Digoxin treats heart failure; accurate dosing prevents toxicity (therapeutic range 0.5–2 ng/mL). Rounded to whole number as instructed.
Question 4 of 5
A nurse is collecting data from a client who has venous insufficiency. Which of the following findings should the nurse expect?
Correct Answer: D
Rationale: Pitting edema is a hallmark of venous insufficiency due to fluid leakage from high venous pressure. Thickened toenails (
A) are fungal-related, shiny skin (
B) and dusky color (
C) indicate arterial insufficiency. Edema reflects venous stasis.
Question 5 of 5
The use of cocaine is higher in which group of people?
Correct Answer: B
Rationale: Hispanic Americans: While substance use varies among populations, Hispanic Americans do not have the highest reported rates of cocaine use. Whites: In terms of drug use by race, White Americans have the highest rates of drug use and abuse. This is likely due to a variety of factors, including socio-economic status, access to drugs, and cultural factors. Asian Americans: Asian Americans typically report lower rates of cocaine use compared to other groups. African Americans: African Americans report lower lifetime use of cocaine, at 8.5%, compared to White Americans (17.6%) and Hispanics (11.1%).
