Which test for HIV is used primarily as a confirmatory test rather than a generalized screening test?
Enzyme immunoassay.
Western Blot.
White blood cell differential.
CD4+ cell count.
The Correct Answer is B
A. Enzyme immunoassay. The enzyme immunoassay (EIA), also known as the ELISA test, is used as a primary screening test for HIV. If the EIA test is positive, a confirmatory test, such as the Western Blot, is performed to ensure accuracy.
B. Western Blot. The Western Blot is a confirmatory test for HIV used to verify positive results from an initial screening test. It detects specific HIV antibodies and is highly specific, reducing the likelihood of false positives.
C. White blood cell differential. A white blood cell (WBC) differential assesses the overall immune response but does not diagnose HIV. While some HIV patients may show low WBC counts, this test is not specific for HIV infection.
D. CD4+ cell count. CD4+ cell count is used to monitor disease progression and immune function in HIV-positive patients, but it is not a confirmatory test for diagnosing HIV. A low CD4+ count suggests HIV progression toward AIDS rather than initial diagnosis.

Correct Answer is C
Explanation
A. Dedicated breastfeeding for 6 months. Exclusive breastfeeding for at least 6 months is recommended by the American Academy of Pediatrics (AAP) and is associated with a lower risk of childhood obesity. Breastfeeding helps regulate appetite and metabolism.
B. Consumption of whole milk as a toddler. Whole milk is recommended from ages 1 to 2 years for brain development and growth. While excessive milk intake may contribute to weight gain, it is not a primary risk factor for early childhood obesity.
C. Introduction of fortified cereal before 4 months of age. Introducing solid foods before 4 months is linked to an increased risk of childhood obesity. Early introduction may disrupt natural hunger and satiety cues, leading to overeating later in life. The AAP recommends introducing solid foods around 6 months of age.
D. Exclusive soy-based formula for the first year of life. Soy-based formula is nutritionally comparable to cow's milk-based formula. While formula feeding in general has been associated with a slightly higher risk of obesity than breastfeeding, soy formula itself is not a direct risk factor for obesity.
Correct Answer is ["A","B","C"]
Explanation
A. Monitor the client's white blood cell count. An elevated white blood cell (WBC) count indicates infection and inflammation. Since MRSA is a bacterial infection, monitoring WBC levels helps assess the severity of the infection and response to treatment.
B. Send wound drainage for culture and sensitivity. A wound culture and sensitivity test confirm the presence of MRSA and determine the most effective antibiotic therapy. This is essential to ensure appropriate treatment and prevent antibiotic resistance.
C. Institute contact precautions for staff and visitors. MRSA is transmitted via direct contact, especially through wound drainage. Contact precautions include wearing gloves and gowns when handling the patient or contaminated materials to prevent the spread of infection.
D. Explain the purpose of a low bacteria diet. A low-bacteria diet (neutropenic diet) is used for immunocompromised patients, such as those undergoing chemotherapy, but it is not relevant for MRSA. The focus should be on infection control and wound care rather than dietary restrictions.
E. Use standard precautions and wear a mask. While standard precautions should always be followed, a mask is not necessary unless performing aerosol-generating procedures or if MRSA is present in the respiratory tract. In this case, contact precautions (gown and gloves) are the primary infection control measures.
