A nurse is caring for a child who has pertussis, also known as whooping cough, which is caused by Bordetella pertussis bacteria. Which of the following types of isolation should the nurse use for this patient?

Choice A reason: Asking the patient to tell their name and date of birth is a way to confirm their identity and match it with the medication order. This is one of the steps of the "five rights" of medication administration, which are the right patient, the right drug, the right dose, the right route, and the right time.

Choice B reason: Asking the patient about their allergies or adverse reactions to medications is important, but it is not a way to ensure patient safety in terms of identification. The nurse should have checked the patient's allergy status before preparing the medication.

Choice C reason: Asking the patient how they feel today and if they have any pain or discomfort is a way to assess their condition and provide comfort measures, but it is not a way to ensure patient safety in terms of identification. The nurse should have done this assessment earlier in the shift or during the medication administration process.

Choice D reason: Asking the patient what is the name of the medication and why they are taking it is a way to educate them about their treatment and check their understanding, but it is not a way to ensure patient safety in terms of identification. The nurse should have done this education before or after giving the medication.

Choice A reason: The MMR vaccine, which protects against measles, mumps, and rubella, is given in two doses, but not before starting school. The first dose is given at 12 to 15 months of age, and the second dose is given at 4 to 6 years of age.

Choice B reason: The DTaP vaccine, which protects against diphtheria, tetanus, and pertussis, is given in five doses, but not at age 11. The first three doses are given at 2, 4, and 6 months of age, the fourth dose is given at 15 to 18 months of age, and the fifth dose is given at 4 to 6 years of age. A booster dose of Tdap, which is a similar vaccine for older children and adults, is given at 11 to 12 years of age.

Choice C reason: The hepatitis B vaccine, which protects against hepatitis B virus infection, is given in three doses in the first year of life. The first dose is given at birth, the second dose is given at 1 to 2 months of age, and the third dose is given at 6 to 18 months of age.

Choice D reason: The varicella vaccine, which protects against chickenpox, is given in two doses, but not at age 12. The first dose is given at 12 to 15 months of age, and the second dose is given at 4 to 6 years of age.
