After a transurethral resection of the prostate (TURP), a client has bloody urine output with large clots. The nurse implements the postoperative prescription to irrigate the indwelling catheter PRN to maintain the catheter's patency. Which action should the nurse implement?

- B. Manually irrigate the catheter with sterile saline as prescribed

A client is brought to the ED by ambulance in cardiac arrest with cardiopulmonary resuscitation (CPR) in progress. The client is intubated and is receiving 100% oxygen per self-inflating (ambu) bag. The nurse determines that the client is cyanotic, cold, and diaphoretic. Which assessment is most important for the nurse to obtain?
- A. Breath sounds over bilateral lung fields.
- B. Carotid pulsation during compressions
- C. Deep tendon reflexes
- D. Core body temperature
Correct Answer: A
Rationale: Assessing breath sounds ensures that the endotracheal tube is properly placed and that ventilation is effective, which is critical in a cardiac arrest situation.
Which intervention should the nurse plan to decrease cardiac demands in an infant with congestive heart disease (CHD)?
- A. Organize nursing activities to allow for uninterrupted sleep.
- B. Allow the infant to sleep through feedings during the night.
- C. Wait for the infant to cry to show definite signs of hunger.
- D. Discourage parents from rocking the infant.
Correct Answer: A
Rationale: The infant requires rest and conservation of energy for feeding. Every effort is made to organize nursing activities to allow for uninterrupted periods of sleep. Whenever possible, parents are encouraged to stay with their infant to provide the holding, rocking, and cuddling that help children sleep more soundly. To minimize disturbing the infant, changing bed linens and complete bathing are done only when necessary. Feeding is planned to accommodate the infant’s sleep and wake patterns. The child is fed at the first sign of hunger, such as when sucking on fists, rather than waiting until he or she cries for a bottle because the stress of crying exhausts the limited energy supply. Because infants with CHD tire easily and may sleep through feedings, smaller feedings every 3 hours may be helpful.
