Question 1 of 5
A nurse is monitoring a client who has diabetes mellitus and a glucose level of 384 mg/dL. Which of the following findings should the nurse identify as an indication of metabolic acidosis?
Correct Answer: C
Rationale: Increased respiratory rate (Kussmaul breathing) compensates for acidosis in diabetic ketoacidosis.
Question 2 of 5
A nurse is reviewing the results of a client's fecal occult blood screening test. Which of the following findings from the client's history should the nurse identify as potentially causing a false-positive result?
Correct Answer: B
Rationale: Fecal occult blood tests detect hidden blood in stool, often for colorectal cancer screening, but false positives can skew results. Ibuprofen, an NSAID, irritates the gastric mucosa, causing microbleeding that may appear in stool, unrelated to colonic sources. Citrus juice doesn't affect heme detection vitamin C may cause false negatives, not positives, and 3 days prior minimizes impact. A hemorrhoidectomy 1 year ago is healed, unlikely to bleed now unless complications persist, which isn't suggested. Breast cancer history doesn't influence gastrointestinal bleeding unless metastatic, an unlikely scenario here. Ibuprofen's known GI side effects align with testing guidelines (e.g., avoiding NSAIDs pre-test), making it the most likely false-positive trigger, requiring the nurse to clarify timing and adjust interpretation.
Question 3 of 5
A nurse is reinforcing teaching with a client who wants to lose 0.9 kg (2 lb.) of body fat per week. The nurse knows that 0.45 kg (1 lb.) of body fat is equal to 3,500 calories. The nurse should instruct the client to reduce his daily caloric intake by how many calories? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 1000
Rationale: Calculation: 2 lb × 3,500 cal/lb = 7,000 cal/week. 7,000 ÷ 7 days = 1,000 cal/day reduction to lose 2 lb weekly.
Question 4 of 5
An occupational health nurse is interpreting the results of a tuberculin skin test for a group of clients who received the test 48 hr ago. Which of the following clients should the nurse identify as having a positive test result?
Correct Answer: C
Rationale: An induration of 15 mm after 48 hours indicates a positive TB skin test, suggesting exposure or infection. Smaller indurations, scabbing, or bruising do not meet the criteria for a positive result.
