A nurse is preparing to administer the measles, mumps, and rubella (MMR) vaccine to an adolescent. Which of the following should the nurse identify as a contraindication to administering this vaccine?

Current pregnancy.

Mild ear infection.

Family history of seizures.

Severe peanut allergy.

Answer and Explanation

The Correct Answer is A

Choice A rationale:
Correct Choice. Current pregnancy is a contraindication to administering the measles, mumps, and rubella (MMR) vaccine. The MMR vaccine contains live attenuated viruses, and it is generally contraindicated during pregnancy due to the potential risk to the developing fetus. Pregnant individuals should wait until after giving birth to receive the MMR vaccine.
Choice B rationale:
Mild ear infection is not a contraindication to administering the MMR vaccine. Mild illnesses, such as mild upper respiratory infections or low-grade fevers, are not typically considered contraindications for vaccination. In fact, immunization might be recommended in these cases to ensure protection against preventable diseases.
Choice C rationale:
A family history of seizures is not a contraindication to administering the MMR vaccine. Seizures are not known to be associated with the MMR vaccine. Therefore, a family history of seizures would not preclude an individual from receiving the vaccine.
Choice D rationale:
Severe peanut allergy is not a contraindication to administering the MMR vaccine. Allergies, including severe peanut allergies, are not considered contraindications for the MMR vaccine. Only individuals with a known severe anaphylactic allergy to a vaccine component (such as gelatin or neomycin) would have a contraindication to receiving the vaccine.

Correct Answer is A

Explanation

Choice A rationale:
A positive leukocyte esterase test indicates the presence of white blood cells (leukocytes) in the urine, which can be an indicator of a urinary tract infection (UTI). White blood cells are part of the body's immune response and their presence in the urine suggests inflammation and infection in the urinary tract.
Choice B rationale:
Deep gold-colored urine is not typically associated with a urinary tract infection. Normally, urine color can vary based on hydration, diet, and other factors, but color alone is not a reliable indicator of a UTI.
Choice C rationale:
The osmolality of 700 mOsm/L is not a specific finding related to urinary tract infections. Osmolality measures the concentration of particles in the urine and can vary based on hydration status. While it might be elevated in a concentrated urine sample, it is not a direct indicator of a UTI.
Choice D rationale:
A specific gravity of 1.015 is within the normal range and does not necessarily indicate a urinary tract infection. Specific gravity measures the concentration of solutes in the urine and can be influenced by hydration levels and kidney function. A UTI would primarily be indicated by the presence of white blood cells and other signs of infection in the urine.

A. 8.6 to 9.5 kg (19 to 21 lb). B. 4.1 to 5 kg (9 to 11 lb). C. 6.8 to 7.7 kg (15 to 17 lb). D. 10.4 to 11.3 kg (23 to 25 lb).

Correct Answer is C

Explanation

The correct answer is choice C. 6.8 to 7.7 kg (15 to 17 lb).

Choice A rationale:

This weight range is above the average for a 6-month-old infant. According to growth charts, the 50th percentile weight for a 6-month-old male is approximately 7.9 kg (17 lb 8 oz), and for a female, it’s about 7.3 kg (16 lb 1 oz). Therefore, 8.6 to 9.5 kg would be considered above average and not the anticipated weight for most infants.

Choice B rationale:

This weight range is below the average for a 6-month-old infant. The average weight at 6 months is significantly higher than 4.1 to 5 kg, as infants are expected to double their birth weight by 5 months of age. Therefore, an infant weighing between 9 to 11 lb at 6 months would be considered underweight.

Choice C rationale:

This weight range is within the average for a 6-month-old infant. As mentioned, the 50th percentile weights for 6-month-old infants are approximately 7.9 kg for males and 7.3 kg for females. This choice falls within the expected weight gain trajectory where an infant is anticipated to double their birth weight by 5 months and then gain an additional pound or so by 6 months.

Choice D rationale:

This weight range is significantly above the average for a 6-month-old infant. It is well above the 95th percentile for this age group and would be considered unusual without underlying health conditions that could contribute to such a weight at this age. An infant weighing between 23 to 25 lb at 6 months would be exceptionally rare and likely indicative of an abnormal growth pattern.
