### Laboratory and Diagnostic Tests
1. QUESTION: Which laboratory result should immediately be
reported by the nurse to the primary care provider (PCP)?
a. Hemoglobin: 15.6
b. Hematocrit: 32%
c. Red blood cells: 5.3
d. White blood cells: 6000
Answer: b
Rationale: The document provides "b" (Hematocrit: 32%).From your previous document, "types of lab/diagnostic testing to determine infection" lists "CBC" and "Differential WBC (normal range 5k-10k/mm3)," implying hematocrit is part of CBC. 32% is below typical normal (38-50%), suggesting anemia or blood loss, requiring immediate reporting.Hemoglobin 15.6 g/dL (a), RBC 5.3 million/mm³ (c), and WBC 6000/mm³ (d, within 5k-10k) are normal.
2. QUESTION: The patient states that she has been taking
warfarin, an anticoagulant, for several years. The nurse notices several bruised areas on her arms. Which of the following
- | P a g e
laboratory results is the most clinically significant for this medication?
a. Platelets: 450,000
b. Prothrombin time: 24.2 seconds
c. Activated partial thromboplastin time: 30 seconds
d. Fibrinogen: 350 mg/dL
Answer: b
Rationale: The document provides "b" (Prothrombin time: 24.2 seconds). Warfarin prolongs PT (normal 11-13.5 seconds), and 24.2 seconds indicates excessive anticoagulation, explaining bruising. Platelets 450,000/mm³ (a) is slightly high, APTT 30 seconds (c) is normal (25-35 seconds, heparin-related), and fibrinogen 350 mg/dL (d) is normal (200-400 mg/dL), less relevant to warfarin.
3. QUESTION: The patient tells the nurse that she has been on a
high-protein, low-carbohydrate diet for the past 6 months.Which blood test results could be influenced by her diet?
- Bilirubin
- Creatinine
- Blood urea nitrogen
- Creatine kinase
Answer: c
- | P a g e
Rationale: The document provides "c" (Blood urea nitrogen).
BUN reflects protein metabolism, rising with high-protein intake. "A patient is admitted with advanced liver disease" lists BUN (18 mg/dL), linking it to metabolism. Bilirubin (a, liver), creatinine (b, kidney/muscle), and creatine kinase (d, muscle damage) are less diet-affected.
4. QUESTION: The nurse is working at a health fair and
providing information about reducing the risk of heart disease.A male asks what his ideal numbers should be for cholesterol and triglycerides. Which of the following are recommended levels for lipid?
a. Total cholesterol: >200 mg/dL
b. HDL: >45 mg/dL
c. LDL: >100 mg/dL
d. Triglycerides: >160 mg/dL
Answer: b
Rationale: The document provides "b" (HDL: >45 mg/dL).HDL >45 mg/dL is desirable for men to reduce heart risk. Total cholesterol >200 mg/dL (a), LDL >100 mg/dL (c), and triglycerides >160 mg/dL (d) exceed typical targets (<200, <100, <150 mg/dL, respectively).
5. QUESTION: The nurse is preparing a patient for a barium
swallow test. Which statements by the patient indicate that the
- | P a g e
patient has understood the nurse's teaching? (Select all that apply.)
- "The doctor will be able to view my stomach and intestines
- "I should increase fluids after the test."
- "I will have to drink a contrast agent."
- "Barium can cause constipation and I may need a mild
- "I will be NPO for 8 hours after the test."
- "My stools may turn black for a few days afterward."
during the test."
laxative."
Answer: a, b, c, d
Rationale: The document provides "a, b, c, d." Barium
swallow uses contrast (c) to view the stomach (a). Post-test fluids (b) and laxatives (d) address barium’s constipating effect.NPO post-test (e) is incorrect (required before), and black stools (f) indicate bleeding, not barium (which whitens stools).
6. QUESTION: A patient has a 24-hour urine specimen ordered
for creatinine clearance. Which instruction is correct?
- "Collect all urine from the time the collection begins until it
- "Save only a sample from each voiding."
- "Clean the perineal area three times before you begin to
ends."
urinate."
