A nurse is preparing a client who has a small bowel obstruction for insertion of a nasogastric tube. Which of the following equipment should the nurse gather prior to the procedure?

The nurse should clarify the prescription for cefazolin with the provider. Cefazolin is a cephalosporin antibiotic, and there is a risk of cross-reactivity in individuals who have an allergy to penicillin.

a) Doxycycline and b) Vibramycin (which is another name for doxycycline) are tetracycline antibiotics and are not related to penicillin.

d) Gentamicin is an aminoglycoside antibiotic and is also not related to penicillin.

Placenta previa is a condition where the placenta partially or completely covers the opening of the cervix. One of the hallmark signs of placenta previa is painless vaginal bleeding, typically bright red in color. This bleeding can occur spontaneously or during activities that put pressure on the uterus, such as sexual intercourse or physical exertion.

A rigid abdomen is not typically associated with placenta previa. It may indicate other conditions, such as peritonitis or abdominal muscle rigidity, but it is not a characteristic finding of placenta previa.

Persistent uterine contractions are not typically associated with placenta previa. Placenta previa is more commonly associated with painless bleeding rather than contractions. However, if placenta previa is complicated by other factors, such as placental abruption, contractions and abdominal pain may be present.

Fetal movement is not directly related to placenta previa. Fetal movement can vary from person to person and does not specifically indicate placenta previa. However, it is important for the nurse to assess fetal well-being in clients with placenta previa as bleeding can impact the oxygen supply to the fetus.
