1. What is a chemical reaction between drugs before their administration or absorption known as?

• A. a drug incompatibility
• B. a side effect
• C. an adverse event
• D. an allergic response

Correct answer: A

Rationale: A chemical reaction between drugs before their administration or absorption is termed a drug incompatibility. This phenomenon commonly happens when drug solutions are mixed before intravenous administration, but it can also occur with orally administered drugs. Choices B, C, and D are incorrect because side effects, adverse events, and allergic responses occur after the administration and absorption of drugs, not prior to it.

2. A patient has suffered a left CVA and developed severe hemiparesis resulting in a loss of mobility. The nurse notices on assessment that an area over the patient's left elbow appears as non-blanchable erythema, and the skin is intact. The nurse should score the patient as having which of the following?

• A. Stage I pressure ulcer
• B. Stage II pressure ulcer
• C. Stage III pressure ulcer
• D. Stage IV pressure ulcer

Correct answer: A

Rationale: Erythema with the skin intact is characteristic of a Stage I pressure ulcer. At this stage, the skin is not broken, but there is localized redness that does not blanch when pressed. Stage II pressure ulcers involve partial-thickness skin loss, Stage III pressure ulcers have full-thickness skin loss, and Stage IV pressure ulcers extend to deeper tissues, including muscle and bone. In this case, the non-blanchable erythema with intact skin aligns with the characteristics of a Stage I pressure ulcer.

3. When choosing a needle gauge for an intramuscular injection in a 12-year-old boy, which of the following gauges would you choose?

• A. 27 gauge
• B. 25 gauge
• C. 22 gauge
• D. 20 gauge

Correct answer: C

Rationale: The correct answer is 22 gauge. A 22-gauge needle is recommended for school-age children, toddlers, and adolescents due to their muscle mass and tolerance. In infants, a smaller gauge (23-25) is preferred as their muscles are less developed and more sensitive. Choice A, 27 gauge, is too thin for an intramuscular injection in a 12-year-old boy. Choice B, 25 gauge, is more suitable for infants than for a 12-year-old. Choice D, 20 gauge, is too thick and not typically used for intramuscular injections in children.

4. A nurse is weighing a breastfed 6-month-old infant who has been brought to the pediatrician's office for a scheduled visit. The infant's weight at birth was 6 lb 8 oz. The nurse notes that the infant now weighs 13 lb. What action should the nurse take?

• A. Tell the mother to decrease the daily number of feedings because the weight gain is excessive.
• B. Tell the mother that the infant's weight is increasing as expected.
• C. Tell the mother that the infant should continue with breast milk as the weight gain is adequate.
• D. Tell the mother that semisolid foods should not be introduced until the infant's weight stabilizes.

Correct answer: B

Rationale: The correct answer is to inform the mother that the infant's weight gain is normal. Infants typically double their birth weight by 6 months, which is precisely the case here, with the infant's weight increasing from 6 lb 8 oz to 13 lb. This weight gain indicates healthy growth and development. Therefore, there is no need to decrease feedings. The infant should continue with breast milk as it is providing adequate nutrition. Additionally, introducing semisolid foods is usually recommended between 4 and 6 months of age, so there is no indication to delay based on the infant's weight gain.

5. The test used to differentiate sickle cell trait from sickle cell disease is:

• A. Sickle cell preparation.
• B. Peripheral smear.
• C. Sickledex.
• D. Hemoglobin electrophoresis

Correct answer: D

Rationale: The correct test to differentiate between sickle cell trait and sickle cell disease is hemoglobin electrophoresis. This test separates different types of hemoglobin based on their electrical charge, allowing for the identification of specific hemoglobin variants like HbS in sickle cell disease. Sickle cell preparation and Sickledex are not specific tests for this differentiation. While a peripheral smear can show sickle cells, it does not provide a definitive differentiation between the trait and the disease as it doesn't identify the specific hemoglobin variant present.
