A nurse is providing teaching to the parent of an infant about car seat safety. Which of the following statements by the parent indicate an understanding of the teaching?

A. Dry mouth: Dry mouth is not a common adverse effect of cefazolin. It is more commonly associated with other medications, such as anticholinergic drugs. While dry mouth may be uncomfortable, it is not typically considered a serious adverse effect of cefazolin that requires immediate reporting.

B. Constipation: Constipation is also not a common adverse effect of cefazolin. It is more commonly associated with other medications, dietary factors, or underlying medical conditions. Similar to dry mouth, constipation is not typically considered a serious adverse effect of cefazolin that requires immediate reporting.

C. Back pain: Back pain is not a common adverse effect of cefazolin. While musculoskeletal adverse effects can occur with some antibiotics, back pain is not typically associated with cefazolin. However, if severe or persistent back pain occurs, it should be reported to the healthcare provider for evaluation.

D. Urticaria: Urticaria, also known as hives, is a potential adverse effect of cefazolin and other antibiotics. It is characterized by raised, itchy welts on the skin and can be a sign of an allergic reaction. Urticaria should be reported to the healthcare provider immediately, as it may indicate a serious allergic reaction requiring prompt medical attention.

A. Temperature of 38°C (100.4°F):A mild fever is not a contraindication for the MMR vaccine. In fact, a low-grade fever is common after immunizations and does not warrant withholding the vaccine.

B. Family history of sudden unexpected infant death (SUID): While a family history of SUID may be concerning, it is not a contraindication for administering the MMR vaccine. This history would not directly impact the safety or effectiveness of the vaccine.

C. Taking an antihistamine for seasonal allergies: Taking an antihistamine for seasonal allergies does not typically contraindicate the administration of the MMR vaccine. Antihistamines are generally safe to use with vaccines, and they do not interfere with the immune response to the vaccine.

D. Receiving prednisone for nephrotic syndrome:Prednisone is an immunosuppressive medication. Children receiving high-dose corticosteroids (such as prednisone) should avoid live vaccines like MMR
