The client's arterial blood gases reveal the following results: pH 7.51, PaO2 80 mmHg, PaCO2 28 mmHg, HCO3 24 mEq/L, O2 saturation 92%. The nurse interprets this blood gas result as:

Table 9.9 Normal Arterial Blood Gas Values

ABG Value	Normal Range
PH	7.35-7.45
PaCO2	35-45 mm Hg
HCO3-	22-26 mEq/L
Base excess	-2 to +2
PaO2	80-95 mm Hg
SaO2	>95%

A. Using a cold compress is typically employed for reducing swelling or discomfort, but it does not address the visual deficits associated with homonymous hemianopia. This intervention would not assist the client in compensating for their visual field loss.
B. Teaching scanning techniques involves training the client to actively search for visual information from their affected side. This can include turning their head and using their eyes to scan to the left (for right homonymous hemianopia) or to the right (for left homonymous hemianopia). This compensatory strategy is crucial for helping the client navigate their environment safely and effectively during rehabilitation.
C. Applying an eye patch is not appropriate for homonymous hemianopia, as it may further limit visual input. In fact, patching could exacerbate difficulties by reducing overall vision and is generally more relevant for conditions like amblyopia or for treating diplopia (double vision), rather than compensating for a visual field deficit.
D. Using eye drops is typically for treating dry eyes, redness, or other ocular conditions, and does not directly address the issues related to homonymous hemianopia. This intervention would not help the client learn to compensate for their visual field loss.

A. This option is not the most relevant for penile cancer detection. While swelling and ulcerated areas may be associated with various conditions affecting the scrotum, they are not specifically indicators of penile cancer. Penile cancer is more typically associated with changes in the penis itself rather than the scrotum.
B. Early signs of penile cancer may include a nodular or wart-like growth on the penis, especially on the glans (head) or shaft. These growths can be painless, making regular self-examination important for early detection. This statement demonstrates an understanding of one of the key indicators of penile cancer.
C. While penile discharge can indicate various conditions, including infections or sexually transmitted diseases, it is not a specific sign of penile cancer. This response does not reflect a direct understanding of the early detection of penile cancer.
D. Pain during urination can be caused by many conditions, such as infections or urinary tract issues, and is not a definitive sign of penile cancer. Additionally, many cases of penile cancer may not present with pain at all, particularly in the early stages.
