After reviewing the child's immunization record, which scheduled vaccine should the nurse prepare to administer next?

Correct Answer: D

Rationale: The correct answer is DTaP. DTaP is administered at 2, 4, and 6 months of age; between 15 and 18 months of age; and between 4 and 6 years of age. Since the child has only received three doses of this vaccine, the next dose of DTaP should be administered. The other options are incorrect because Hib is administered at 2, 4, and 6 months of age and between 12 and 15 months; IPV is administered at 2, 4, and 6 months of age and between 4 and 6 years of age; MMR is administered between 12 and 15 months of age and again between 4 and 6 years of age.

Correct Answer: D

Rationale: The correct answer is hepatitis A. DTaP, MMR, and Hib are all part of the regular schedule of immunizations for children to protect them against diseases like diphtheria, tetanus, pertussis, measles, mumps, rubella, and Haemophilus influenzae type b. Hepatitis A vaccine is not included in the routine childhood immunization schedule but may be recommended in certain situations or regions where the disease is more prevalent. Hepatitis A is generally considered an optional vaccine for children but can be administered based on specific risk factors or regional guidelines.

Correct Answer: A

Rationale: In this scenario, the Rh-negative woman has been sensitized, posing a risk to any Rh-positive fetus she delivers. The most appropriate nursing action is to provide emotional support to help the family cope with the infant's condition. This includes addressing potential outcomes like death or neurological damage. Administering MICRhoGam (Choice B) to a sensitized woman is not recommended; it is only given post-abortion or ectopic pregnancy to prevent sensitization. Rh-immune globulin is not administered to the newborn (Choice C) in this case. Analyzing the maternal Direct Coombs' test (Choice D) is unnecessary; instead, an Indirect Coombs' test is used to assess sensitization. Therefore, the correct nursing action is to offer emotional support to the family, acknowledging the challenges they may face.

Correct Answer: A

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

Correct Answer: B

Rationale: Head lag should be completely resolved by 4 months of age. Continuing head lag at 6 months of age indicates the need for further developmental or neurological evaluation. Laying the infant on his stomach promotes muscle development of the neck and shoulder muscles, but because of the age of this child, a referral should be the first action. The findings are abnormal for a 6-month-old infant. Significant head lag can be seen in infants with Down syndrome and hypoxia, as well as neurological and other metabolic disorders. While some of these disorders might include developmental delays, stating this to the parents without a proper evaluation can cause unnecessary distress. The priority is to identify the cause of the head lag through a medical evaluation before discussing potential outcomes with the parents.
