The nurse is caring for a child after heart surgery. What should the nurse do if evidence of cardiac tamponade is found?
- A. Increase analgesia
- B. Apply warming blankets
- C. Immediately report this to physician
- D. Encourage child to cough, turn, and breathe deeply
Correct Answer: C
Rationale: If evidence of cardiac tamponade is found in a child after heart surgery, it is crucial for the nurse to immediately report this to the physician. Cardiac tamponade is a serious condition where excess fluid or blood accumulates in the pericardial sac, compressing the heart and affecting its ability to pump effectively. Prompt recognition and intervention are essential to prevent potential life-threatening outcomes. The physician would need to assess the child's condition, consider performing procedures to relieve the tamponade such as pericardiocentesis, and provide appropriate treatment to stabilize the child. Delaying reporting and action in cases of cardiac tamponade can lead to further complications and worsen the child's condition.

A client has a serum calcium level of 7.2mg/dl. During the physical examination, the nurse expects to assess:
- A. Trousseau's sign
- B. Hegar's sign
- C. Homan's sign
- D. Goodell's sign
Correct Answer: A
Rationale: A client with a low serum calcium level (hypocalcemia) is at risk for exhibiting Trousseau's sign. Trousseau's sign is a clinical manifestation of hypocalcemia characterized by carpal spasm induced by inflating a blood pressure cuff on the arm above the systolic pressure for a few minutes. This spasm occurs due to the increased neuromuscular irritability caused by low calcium levels. Therefore, a nurse assessing a client with a serum calcium level of 7.2mg/dl should expect to assess Trousseau's sign.
The parents of a 3-month-old infant report that their infant sleeps supine (face up) but is often prone (face down) while awake. What knowledge should the nurse's response should be based?
- A. Unacceptable because of the risk of sudden infant death syndrome (SIDS)
- B. Unacceptable because it does not encourage achievement of developmental milestones
- C. Acceptable to encourage fine motor development
- D. Acceptable to encourage head control and turning over
Correct Answer: D
Rationale: The correct knowledge that the nurse's response should be based on is that it is acceptable to encourage head control and turning over. At 3 months of age, encouraging the infant to be prone while awake can help promote the development of head control, neck strength, and eventually facilitate the ability to turn over. This practice is considered safe and beneficial for infants within the appropriate age range, as long as the infant is supervised during the awake period. It is important to promote safe sleep practices for infants to reduce the risk of Sudden Infant Death Syndrome (SIDS), but allowing supervised tummy time for an awake infant is beneficial for their motor development.
