A client with B negative blood requires a blood transfusion during surgery. If no B negative blood is available, the client should be transfused with:
- A. A positive blood
- B. B positive blood
- C. O negative blood
- D. AB negative blood
Correct Answer: C
Rationale: O negative blood is the universal donor type, safe for all recipients, including B negative, as it lacks A, B, and Rh antigens, minimizing transfusion reactions.

The nurse is teaching a group of prenatal clients about the effects of cigarette smoke on fetal development. Which characteristic is associated with babies born to mothers who smoked during pregnancy?
- A. Low birth weight
- B. Large for gestational age
- C. Preterm birth,but appropriate size for gestation
- D. Growth retardation in weight and length
Correct Answer: A
Rationale: Smoking during pregnancy restricts placental blood flow leading to low birth weight. Babies are not typically large and while preterm birth or growth retardation may occur low birth weight is the most consistent finding.
A client delivered a term infant 1 hour ago. Her uterus on assessment is boggy and is U+1 in contrast to the previous assessment of U-2. The immediate nursing response is to:
- A. Administer methergine IM
- B. Remove the retained placental fragments
- C. Assist the client to the bathroom and provide cues to stimulate urination
- D. Massage the fundus until firm
Correct Answer: D
Rationale: Methergine is given following placental delivery to promote uterine contractions and prevent hemorrhage. Methergine may be administered in this clinical situation, but fundal massage would be the first response. Removal of retained placental fragments is done by the physician and is not the first response. If the fundus rises and is deviated, particularly to the right, the nurse should suspect bladder distention secondary to bladder and urethral trauma associated with birth and decreased bladder tone following delivery. Therefore, women have a diminished sensation to void. A boggy fundus rises and is indicative of blood pooling, predisposing the woman to clot formation. Massage the uterus until firm. Too vigorous massage will result in atonia. Clots may be expelled by a kneading motion of the uterus by the nurse.
The nurse is assessing a client with suspected deep vein thrombosis (DVT). Which finding is most indicative?
- A. Bilateral leg edema
- B. Warm, red, swollen calf
- C. Mild leg cramping
- D. Pale, cool foot
Correct Answer: B
Rationale: A warm, red, swollen calf is a classic sign of DVT due to clot-related inflammation. Bilateral edema (A) suggests heart failure, cramping (C) is nonspecific, and pale/cool foot (D) indicates arterial occlusion.
An 18-year-old girl is admitted to the hospital with a depressed skull fracture as a result of a car accident. If the nurse were to observe a rising pulse rate and lowering blood pressure, the nurse would suspect that the client:
- A. Has a sudden and severe increase in intracranial pressure
- B. Has sustained an internal injury in addition to the head injury
- C. Is beginning to experience a dangerously high level of anxiety
- D. Is having intracranial bleeding
Correct Answer: B
Rationale: Rising pulse rate and lowering blood pressure are indicative of hypovolemia, which is consistent with an internal injury causing blood loss.
The client is admitted with a diagnosis of gastroenteritis. Which precaution should the nurse implement?
- A. Standard precautions
- B. Contact precautions
- C. Droplet precautions
- D. Airborne precautions
Correct Answer: B
Rationale: Gastroenteritis is often caused by pathogens like norovirus, requiring contact precautions to prevent fecal-oral transmission. Standard precautions are insufficient, and droplet or airborne are not indicated.
