Which of the ff is the result of central nervous system manifestations?
- A. Congestive Heart Failure c.Valve damage
- B. Chorea
- C. Pericarditis
Correct Answer: B
Rationale: Chorea is the result of central nervous system manifestations. Chorea is a movement disorder characterized by involuntary, brief, random, and irregular muscle movements that are often seen in neurological conditions such as Huntington's disease. The central nervous system is responsible for controlling and coordinating movements, so any dysfunction in the central nervous system can lead to movement disorders like chorea. Therefore, chorea is directly related to central nervous system manifestations, unlike congestive heart failure, valve damage, or pericarditis which are primarily related to cardiovascular issues.

A patient with abnormal sodium losses is receiving a house diet. To provide 1,600mg sodium daily, the nurse could supplement the patient's diet with:
- A. One beef cube and 8oz of tomato juice
- B. One beef cube and 16oz of tomato juice
- C. Four beef cubes and 8oz of tomato juice
- D. One beef cube and 12oz tomato juice
Correct Answer: D
Rationale: One beef cube typically contains about 800mg of sodium, and 8oz of tomato juice contains approximately 480mg of sodium. Therefore, to provide a total of 1,600mg of sodium daily, the nurse could supplement the patient's diet with one beef cube (800mg sodium) and 12oz of tomato juice (720mg sodium). This combination would effectively provide the required 1,600mg of sodium per day for the patient with abnormal sodium losses.
Why place an undershirt between the skin and the Pavlik harness?
- A. To keep the skin moist
- B. To prevent infection caused by pins of the Pavlik harness
- C. To prevent skin abrasions and irritation by the harness
- D. To keep the skin clean
Correct Answer: C
Rationale: Placing an undershirt between the skin and the Pavlik harness is done to prevent skin abrasions and irritation caused by the harness rubbing directly against the skin. The undershirt acts as a protective layer, reducing the likelihood of skin sensitivity or damage due to the continuous contact with the harness. This is particularly important for infants or young children who may have delicate skin that is more prone to irritation. By using an undershirt, caregivers can help ensure greater comfort for the child while wearing the Pavlik harness and reduce the risk of any skin-related complications.
Children with ALL who carry poor outcome include all the following EXCEPT
- A. age younger than 1 year and older than 10 year
- B. T-cell immunophenotype
- C. hyperdiploidy chromosomal abnormality
- D. initial leukocyte count of > 50,000
Correct Answer: C
Rationale: Hyperdiploidy is generally associated with a favorable prognosis in ALL, unlike other listed factors.
You are assigned to evaluate the outcome of fecal occult blood test as a screening test for patients with bowel cancer. The total number of patients who underwent the test is 2030; in those whom the disease is confirmed are 30. The results of fecal occult blood test are as follows: in 20 patients who has a confirmed bowel cancer (truly positive), and in 180 patients who don't have the disease (falsely positive); in 10 patients who truly has the disease (falsely negative), and in 1820 patients who are not affected by the disease (truly negative). All the following statements are true EXCEPT
- A. the prevalence of the disease for those population is 1.48%
- B. the sensitivity of the test is 67%
- C. the specificity of the test is 91%
- D. the positive predictive value is 20%
Correct Answer: A
Rationale: Prevalence = (Total cases / Total population) * 100 = (30 / 2030) * 100 ≈ 1.48%. This statement is correct, so it is the exception as the question asks for the incorrect statement.
During a breast examination, which finding most strongly suggests that the client has breast cancer?
- A. Slight asymmetry of the breasts
- B. A fixed nodular mass with dimpling of the overlying skin
- C. Bloody discharge from the nipple
- D. Multiple firm, round, freely movable masses that change with the menstrual cycle
Correct Answer: B
Rationale: A fixed nodular mass with dimpling of the overlying skin is the finding that most strongly suggests breast cancer. This presentation is concerning for an invasive carcinoma that has invaded into the surrounding tissues, leading to the dimpling of the skin. Breast cancer typically presents as a painless, hard, irregularly shaped, non-mobile mass. Dimpling of the skin overlying the mass is a sign of advanced disease and is often associated with a poor prognosis. Therefore, this finding should raise suspicion for breast cancer and prompt further evaluation and workup.
