Correct Answer: A

Rationale: Digoxin is a medication commonly used to treat infants with heart conditions. One of the primary concerns with digoxin therapy is the risk of toxicity, which can lead to serious cardiac arrhythmias. Bradycardia, or a heart rate less than 60 beats per minute, is a common sign of digoxin toxicity. Therefore, if a 6-month-old infant receiving digoxin has an apical pulse rate of less than 60 beats/min, the nurse should notify the practitioner and withhold the medication to prevent further complications.

Correct Answer: D

Rationale: According to the American Cancer Society guidelines, women with average risk for breast cancer should start getting mammograms every 2 years starting at age 40. Since the client is not considered at high risk for breast cancer, this recommendation applies to her. Regular mammograms are important for early detection of breast cancer, even in those at average risk. It is also important for the client to perform monthly breast self-exams and report any changes or concerns to her healthcare provider.

Correct Answer: B

Rationale: For effective defibrillation, the paddles should be placed at the apex and right infraclavicular area, ensuring optimal current flow through the heart to terminate life-threatening arrhythmias.
