The nurse is teaching a group of clients about modifiable risk factors for cardiovascular disease. Which of the following should the nurse include in the teaching? (Select all that apply)

A. Fifth left intercostal space at the midclavicular line:

Explanation: The apical pulse, or the point of maximal impulse (PMI), is typically located at the fifth intercostal space at the midclavicular line on the chest. This is the area where the heartbeat is best heard using a stethoscope in most adults.

B. Third left intercostal space at the midclavicular line:

Explanation: This location is too high for the apical pulse. The heart's apex is generally not found at the third intercostal space; it's lower, closer to the fifth intercostal space.

C. Fourth left intercostal space at the sternal border:

Explanation: This location is not the typical site for auscultating the apical pulse. The PMI is usually heard at the midclavicular line, not at the sternal border.

D. Under the left breast at the midclavicular line:

Explanation: This position is not precise enough for auscultating the apical pulse. The specific intercostal space (fifth) and midclavicular line are crucial for accurate assessment.

A. Inform the client that his breast enlargement is benign, and normal for a man of his age:

This choice is not appropriate because while gynecomastia can be benign, it should not be assumed without a proper medical evaluation. Gynecomastia can have various causes, including hormonal imbalances or underlying medical conditions. It's crucial to identify the cause through a medical assessment.

B. Explain that this condition may be the result of hormonal changes, and recommend that he see his physician:

This is the correct choice. Gynecomastia can indeed be caused by hormonal changes, but it can also be due to medications, certain health conditions, or hormonal imbalances. Therefore, the nurse should recommend a medical evaluation to determine the underlying cause and appropriate management.

C. Recommend that he alter his diet to include fewer fats and more lean proteins:

This choice is not relevant to gynecomastia. Gynecomastia is not typically caused by dietary factors, so altering the diet would not be a suitable response to this situation.

D. Explain that gynecomastia in men is usually associated with prostate enlargement and recommend that he be thoroughly screened:

This choice is incorrect. Gynecomastia is not directly associated with prostate enlargement. While both conditions can occur in older men, they are distinct medical issues. Screening for prostate enlargement is not indicated based solely on the presence of gynecomastia. Proper evaluation and assessment of each condition are necessary.
