What does the surgical closure of the ductus arteriosus do?
- A. Stop the loss of unoxygenated blood to the systemic circulation
- B. Decrease the edema in legs and feet
- C. Increase the oxygenation of blood
- D. Prevent the return of oxygenated blood to the lungs
Correct Answer: A
Rationale: The ductus arteriosus is a fetal blood vessel that allows blood to bypass the lungs while in utero. After birth, the ductus arteriosus should close to redirect blood flow through the lungs for oxygenation. Surgical closure of the ductus arteriosus is performed to prevent the shunting of unoxygenated blood from the pulmonary artery to the aorta, therefore stopping the loss of unoxygenated blood to the systemic circulation. This helps to ensure that oxygenated blood is properly circulated to the body tissues and organs.

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 52-year old female tells the nurse that she has found a painless lump in her right breast during her monthly self- examination. Which assessment finding would strongly suggest that this client's lump is cancerous?
- A. Eversion of the right nipple and mobile mass
- B. Mobile mass that is soft and easily
- C. Non-mobile mass with irregular edges delineated
- D. Non palpable right axillary lymph nodes
Correct Answer: C
Rationale: The assessment finding that strongly suggests that the client's lump is cancerous is a non-mobile mass with irregular edges delineated. Generally, cancerous breast lumps tend to have irregular shapes/edges and lack mobility. This finding is concerning for malignancy because it indicates that the lump is fixed in place and possibly invading nearby tissues, which are characteristics often associated with cancerous tumors. It's essential for the client to undergo further diagnostic tests, such as a biopsy, to confirm the presence of cancer and establish a proper treatment plan.
Which of the ff. would the nurse explain to a patient is the main purpose of a hearing aid?
- A. Amplify background noise
- B. Amplify musical sounds
- C. Occlude the ear
- D. Improve ability to hear
Correct Answer: D
Rationale: The main purpose of a hearing aid is to improve the patient's ability to hear. Hearing aids are devices designed to amplify sound for individuals with hearing loss or difficulty hearing. They do not amplify background noise or musical sounds specifically; instead, they are meant to enhance the overall perception of sounds to help individuals better understand speech and communicate effectively. Moreover, hearing aids do not occlude the ear, but rather are used to transmit sound into the ear canal to make sounds louder and clearer for the wearer.
